Introduction

Accurate cost estimating is essential for the effective management of the New York City, Department of Environmental Protection’s Capital Program. To ensure consistency across all projects and to facilitate review and approval of all cost estimates prepared for the Capital Program, the Bureau of Engineering Design and Construction (BEDC) has developed this Cost Estimating Manual. Key objectives of Manual include the following:

• Standardization in engineering inputs (scope) at all estimating milestones to drive consistency in the expected accuracy range of cost estimates • Standardization of estimating format to facilitate development, review, and historical data capture • Guidance on development of appropriate contingency levels to facilitate better transparency and decision-making in Capital Program budgeting • Standardization in the submittal of estimate supporting documentation including sources of information and assumptions used to develop the estimate • Minimum quality requirements for estimate review prior to submittal to BEDC

The Manual identifies requirements of the entire estimating process covering the following eight major steps in cost estimating:

Estimating Framework

The estimating framework described in this Manual is largely based on the Association for the Advance- ment of Cost Engineering (AACE) Recommended Practice No. 18R-97: Cost Estimate Classification Sys- tem – As Applied in Engineering, Procurement and Construction for the Process Industries. This AACE Recommended Practice has been adapted and expanded to the specific needs and characteristics of the BEDC Capital Program. A copy of this Practice can be obtained from the AACE website at www.aacei.org/ technical/rp.shtml and is included as Attachment 1-1 to this Manual.

AACE Practice 18R-97 utilizes a five level Class System (5, 4, 3, 2, and 1) which corresponds to estimate types prepared at various stages of project development. Type 5 cost estimates are developed a project conception when little project information or scope has been developed. Type 1 estimates are complete detailed unit cost and take off estimates with complete or near complete scope definition. For planning and budgeting purposes, BEDC requires development of project cost estimates at the various milestones within the project life cycle. The correlation between the estimates produced at each of the key BEDC project life cycle milestones and AACE estimate classes is shown in Figure 1.1. For each delivery milestone, the generally accepted estimating methods, expected level of accuracy, level of scope definition, and the key scope content requirements necessary to develop the estimate are identified.

Recommended Practice No. 18R-97 Cost Estimate Classification System – As Applied in Engineering, Procurement, and Construction for the Process Industries

June 15, 1998

PURPOSE

As a recommended practice of AACE International, the Cost Estimate Classification System provides guidelines for applying the general principles of estimate classification to project cost estimates (i.e., cost estimates that are used to evaluate, approve, and/or fund projects). The Cost Estimate Classification System maps the phases and stages of project cost estimating together with a generic maturity and quality matrix, which can be applied across a wide variety of industries. This addendum to the generic recommended practice provides guidelines for applying the principles of estimate classification specifically to project estimates for engineering, procurement, and construction (EPC) work for the process industries. This addendum supplements the generic recommended practice (17R-97) by providing:

• a section that further defines classification concepts as they apply to the process industries; • charts that compare existing estimate classification practices in the process industry; and • a chart that maps the extent and maturity of estimate input information (project definition deliverables) against the class of estimate.

As with the generic standard, an intent of this addendum is to improve communications among all of the stakeholders involved with preparing, evaluating, and using project cost estimates specifically for the process industries. It is understood that each enterprise may have its own project and estimating processes and terminology, and may classify estimates in particular ways. This guideline provides a generic and generally acceptable classification system for process industries that can be used as a basis to compare against. It is hoped that this addendum will allow each user to better assess, define, and communicate their own processes and standards in the light of generally-accepted cost engineering practice.

INTRODUCTION

For the purposes of this addendum, the term process industries is assumed to include firms involved with the manufacturing and production of chemicals, petrochemicals, and hydrocarbon processing. The common thread among these industries (for the purpose of estimate classification) is their reliance on process flow diagrams (PFDs) and piping and instrument diagrams (P&IDs) as primary scope defining documents. These documents are key deliverables in determining the level of project definition, and thus the extent and maturity of estimate input information. Estimates for process facilities center on mechanical and chemical process equipment, and they have significant amounts of piping, instrumentation, and process controls involved. As such, this addendum may apply to portions of other industries, such as pharmaceutical, utility, metallurgical, converting, and similar industries. Specific addendums addressing these industries may be developed over time. This addendum specifically does not address cost estimate classification in nonprocess industries such as commercial building construction, environmental remediation, transportation infrastructure, “dry” processes such as assembly and manufacturing, “soft asset” production such as software development, and similar industries. It also does not specifically address estimates for the exploration, production, or transportation of mining or hydrocarbon materials, although it may apply to some of the intermediate processing steps in these systems. The cost estimates covered by this addendum are for engineering, procurement, and construction (EPC) work only. It does not cover estimates for the products manufactured by the process facilities, or for research and development work in support of the process industries. This guideline does not cover the significant building construction that may be a part of process plants. Building construction will be covered in a separate addendum.

June 15, 1998 This guideline reflects generally-accepted cost engineering practices. This addendum was based upon the practices of a wide range of companies in the process industries from around the world, as well as published references and standards. Company and public standards were solicited and reviewed by the AACE International Cost Estimating Committee. The practices were found to have significant commonalities that are conveyed in this addendum.

COST ESTIMATE CLASSIFICATION MATRIX FOR THE PROCESS INDUSTRIES

The five estimate classes are presented in figure 1 in relationship to the identified characteristics. Only the level of project definition determines the estimate class. The other four characteristics are secondary characteristics that are generally correlated with the level of project definition, as discussed in the generic standard. The characteristics are typical for the process industries but may vary from application to application. This matrix and guideline provide an estimate classification system that is specific to the process industries. Refer to the generic standard for a general matrix that is nonindustry specific, or to other addendums for guidelines that will provide more detailed information for application in other specific industries. These will typically provide additional information, such as input deliverable checklists to allow meaningful categorization in those particular industries.

Notes: [a] The state of process technology and availability of applicable reference cost data affect the range markedly. The +/- value represents typical percentage variation of actual costs from the cost estimate after application of contingency (typically at a 50% level of confidence) for given scope. [b] If the range index value of “1” represents 0.005% of project costs, then an index value of 100 represents 0.5%. Estimate preparation effort is highly dependent upon the size of the project and the quality of estimating data and tools.

June 15, 1998 CHARACTERISTICS OF THE ESTIMATE CLASSES

The following charts (figures 2a through 2e) provide detailed descriptions of the five estimate classifications as applied in the process industries. They are presented in the order of least-defined estimates to the most-defined estimates. These descriptions include brief discussions of each of the estimate characteristics that define an estimate class. For each chart, the following information is provided.

• ANSI Standard Reference (1972) Name: this is a reference to the equivalent estimate class in the existing ANSI standards. • Alternate Estimate Names, Terms, Expressions, Synonyms: this section provides other commonly used names that an estimate of this class might be known by. These alternate names are not endorsed by this Recommended Practice. The user is cautioned that an alternative name may not always be correlated with the class of estimate as identified in the chart. • Description: a short description of the class of estimate, including a brief listing of the expected estimate inputs based on the level of project definition. • Level of Project Definition Required: expressed as a percent of full definition. For the process industries, this correlates with the percent of engineering and design complete. • End Usage: a short discussion of the possible end usage of this class of estimate. • Estimating Methods Used: a listing of the possible estimating methods that may be employed to develop an estimate of this class. • Expected Accuracy Range: typical variation in low and high ranges after the application of contingency (determined at a 50% level of confidence). Typically, this results in a 90% confidence that the actual cost will fall within the bounds of the low and high ranges. • Effort to Prepare: this section provides a typical level of effort (in hours) to produce a complete estimate for a US$20,000,000 plant. Estimate preparation effort is highly dependent on project size, project complexity, estimator skills and knowledge, and on the availability of appropriate estimating cost data and tools.

Figure 4 maps the extent and maturity of estimate input information (deliverables) against the five estimate classification levels. This is a checklist of basic deliverables found in common practice in the process industries. The maturity level is an approximation of the degree of completion of the deliverable. The degree of completion is indicated by the following letters.

• None (blank): development of the deliverable has not begun. • Started (S): work on the deliverable has begun. Development is typically limited to sketches, rough outlines, or similar levels of early completion. • Preliminary (P): work on the deliverable is advanced. Interim, cross-functional reviews have usually been conducted. Development may be near completion except for final reviews and approvals. • Complete (C): the deliverable has been reviewed and approved as appropriate.

Introduction

This Chapter describes the key inputs to the cost estimating process and focuses primarily on the transmittal of project scope definition to the estimating team. Scope definition is consistently identified as the most important factor in estimating accuracy. Scope communication between the engineering and estimating teams is particularly critical in the early stages of project development when little scope is physically shown in the documents. The engineer is expected to work closely with the estimating team throughout the planning and design phases of the project to ensure effective communication of the scope including both what is shown and not shown in the documents. An integrated design and estimating team will help facilitate the scope transfer and cost estimate development process.

The primary cost estimating inputs covered in this chapter are: • General Estimate Preparation • Estimate Work Breakdown Structure • Project Scope (Reports, Drawings, Specifications, etc.) – Scope Definition – Gap Analysis – Scope Change Log • Project Risks • Project Schedule • Pre-Estimate Preparation Meeting

Estimate Preparation Services

In some instances, the engineer is rushed to make a deliverable date and the estimating team may not be given sufficient time to prepare a quality estimate. In other cases, the estimating team may be stretched with workload and not apply adequate time to develop a proper estimate. Independent of cause, a hasty estimate can obviously result in greater estimating error.

The estimating team is encouraged to develop a cost estimating model that can be used to quickly determine the level of effort and cost to provide adequate cost estimating services, meeting all of the requirements outlined in this Manual. Factors that should be considered in the model include but are not limited to the following:

• Cost estimate class (5, 4, 3, 2, or 1) • Estimated total construction cost • Project complexity • Estimated No. of Drawings

2-1 Cost Estimating Manual June 2008

• Availability of effective parametric cost models (for early estimates) • Effectiveness of coordination and communication of design team with estimating team • Average hourly rates of estimating staff

The AACE has an example cost estimating services model that can be downloaded from the website and calibrated based on each estimating team’s historical estimating experience. This model only includes cost and time for the cost estimating function. It does not include the level of effort required of the engineering team to develop the deliverables and coordinate with the estimating team.

To ensure adequate management of the schedule and budget of all estimating services, the consultant engineer shall provide the following information:

• At the beginning of both the facility planning and the design phase of all BEDC projects, the design and estimating team must identify the amount of time required, the number of estimators required, and the schedule for preparation of all estimates. This information must be summarized in the Project Manage- ment Plan and incorporated into the Engineer’s baseline project schedule. Any projected schedule variation or any significant change in the overall project scope should be reported to the estimating team so that the estimating services plan can be adjusted as necessary to ensure adequate time and budget for preparation of a sound cost estimate at all submittal milestones. • In the cover letter for all cost estimates submitted to BEDC, the engineer of record must document the date that the scope package was delivered to the estimating team, the date the project team met with the estimating team to review the information, the date the estimate was returned to the engineer for review, and the date the estimate was submitted to BEDC. The lead estimator should be copied on the correspondence to BEDC. • The consultant’s monthly invoice should include a separate task for cost estimating support and services. The invoice must include an itemized list of the name and corresponding number of hours devoted to cost estimating services during the billing period.

Estimate Work Breakdown Structure (WBS)

The WBS is a hierarchal listing of elements that organizes and defines the scope of the project into man- ageable and definable areas and packages of work. A standard WBS must be created prior to initiating any cost estimating services. The WBS provides the structure in which to produce the estimate and must remain constant throughout each of the project estimating phases. An established WBS provides the following benefits:

1. Drives consistency in the elements and line items included in the cost estimates. 2. Acts as a checklist to ensure all required elements are included in the estimate. 3. Provides a communication tool between the designer and estimator for scope definition at each estimating interval. 4. Provides a framework for allocating costs to scope items not shown at various cost estimating intervals. 5. Facilitates cost reconciliation from one estimate to the next by isolating areas of cost increase. 6. Facilitates review and comparison of cost estimates at both a gross level and detailed level across multiple capital projects.

2-2 Chapter 2 Inputs to Estimating Process

A standard six-level WBS structure has been established for BEDC Capital Projects and is as shown below: Level 1 – Area Level 2 – Process Level 3 – System Level 4 – Group/Division Level 5 – Work Package Level 6 – Assembly

Level 1 – Area Area is the highest level of the WBS and represents a geographical area of the site with a defined boundary that may include one or more process units. Areas may also included non-process parts of a plant including roads, walkways, landscaping, buildings, etc. Examples of typical areas include Headworks, Solids Handling, Primary Clarification, or Effluent Pump Station. The boundaries for an area are generally defined as the footprint of all the process elements that are co-located in the same discrete area. Interconnecting piping and other utilities (between process units) should be assigned to the “General/Site” area.

Level 2 - Process A process unit typically changes the physical properties of whatever enters it or it can be a utility process that enhances or improves the efficiency of the process function. Examples of processes include Primary Clarification, Screening, or Thickening. Depending on the facility, a process under an Area can be one in the same. For example, the Filtration process can be located in the Filtration area along with other processes such as the Filtration Backwash Waste Basin. In other cases the processes can be different from the area. For example, the Screening process is typically located in the Headworks area, along with other processes such as Coarse Solids Reduction, Grit Processing, etc. Many of the elements within any given area are required to complete the facility, but are not necessarily part of any given process. For consistency, items not shown on the P&ID’s (Process and Instrumentation Diagrams) or not directly attributable to systems shown on the P&ID’s, should be assigned to the “General/Building” designation at WBS Level 2. Support elements, such as electrical service, instrumentation, SCADA, that can be attributed to a process and/or system should be assigned to that process/system. To make this distinction, determine if the element would be eliminated if the process/system was eliminated.

Level 3 – System A system is a component of a process that is required in order to achieve the process objective. Examples of systems include Grit Cyclone for the grit removal process, Backwash Pump System for the filtration process, or Chlorine Contact Tank for the Disinfection Process. Capacity and/or sizing information for each system is also provided by the design team. The distinction between a “process” and a “system” can also be explained by the following:

• A process is what is being done to the material in the process stream. • Systems are the physical components that enable the process.

2-3 Cost Estimating Manual June 2008

Since some systems may be optional, depending on process design, and the different types of systems may also accomplish the same purpose with the process, it is essential that the design team define all systems required for a given process.

For items assigned to the “General/Buildings” designation at WBS Level 2, system designations at WBS Level 3 should follow Uniformat II for Major Group Items as defined by ASTM E1557-05 designations. These include:

A – Substructure B – Shell C – Interiors D – Services E – Equipment and Furnishings F – Special Construction and Demolition G – Sitework

For incorporation into the overall WBS for a treatment plant project, the code should be linked together to include the abbreviation for the General/Buildings process as shown below:

G/B-A – Substructure G/B-B – Shell etc.

Level 4 – Group/Division Level 4 organizes project elements into groups (Group Elements in ASTM E1557) and/or CSI major divisions (Divisions 1 through 17).

Level 5 – Work Package The Work Package level is largely where the work packages are broken down based on the discipline, trade, or crew. Work packages are generally the scope of work within each system that would be performed by a specialty subcontractor to the general contractor or by a separate trade discipline/crew within the general contactor’s forces. (In ASTM E 1557 Work Packages are identified as Individual Elements). Examples of Work Packages include Mass Excavation, Structural Excavation, Equipment, Process Piping, Yard Piping, Plumbing, Structural Concrete, Structural Steel, Miscellaneous Metal, Masonry, Electrical, Painting and Coating, etc. A standard list of Work Packages organized by CSI division is included as Attachment 2-1 to this Manual.

Level 6 – Assembly Assembly is the lowest level of the WBS and is where the detailed quantity take-off is performed. Assemblies are used to convert the dimensional information available on the plan to detailed line item quantities in order to calculate the cost of labor, materials, equipment, subcontracts, etc. for the elements shown on the design

2-4 Chapter 2 Inputs to Estimating Process drawings. For example, given the dimensions and rebar sizing/spacing for a slab on grade, the estimator can determine quantities for the detailed line items such as:

• Fine grading/subgrade preparation • Volume of aggregate base (if required) • Vapor barrier (if required) • Formwork area • Concrete volume to buy and place • Surface area of concrete requiring finishing • Quantity of reinforcing steel to buy and install

A partial sample of a WBS for a portion of a wastewater treatment plant is shown below: Level 1(Area) – Headworks Level 2 (Process) - General Level 2 (Process) - Screening Level 2 (Process) – Coarse Solids Reduction Level 2 (Process) – Odor Collection Level 2 (Process) – General/Buildings Level 2 (Process) – Grit/Debris Processing Level 3 (System) – Grit Classifications/Separation and Washing Level 3 (System) - Grit Conveyance Level 3 (System - Grit Receptacle Level 3 (System) – Grit Removal Level 4 (Group/Discipline) – Equipment/Division 11 Level 4 (Group/Discipline) – Piping/Division 15 Level 4 (Group/Discipline) – Electrical/Division 16 Level 5 (Work Package) – Electrical Service and Distribution Level 6 (Assembly) – Equipment Connection Detail Estimate Line Items (included in the assembly): Conduit Wire/Cable Flex Motor Connection Local VFD/Control Station Disconnects Heat Trace

In the example above, multiple processes exist within the same area. Accordingly, systems that are a child of the area (building substructure, building services, building superstructure), but are common to and sup-

2-5 Cost Estimating Manual June 2008 port multiple processes would be assigned to “General/Buildings” at Level 2 as shown below:

Level 1 (Area) – Headworks Level 2 (Process) – Screening Level 2 (Process) – Coarse Solids Reduction Level 2 (Process) – Grit/Debris Processing Level 2 – General/Buildings Level 3 – G/B-A; Substructure Level 4 (Work Package) – Structure Excavation Level 4 (Work Package) – Foundation Level 3 – G/B- Services Level 4 – (Group/Division) – Electrical/Division 17 Level 4 – (Group/Division) – Plumbing/Division 15 Level 4 – (Group/Division) – HVAC/Division 15 Level 4 – (Group/Division) – Fire Protection/Division 15 Level 3 – G/B - Shell Level 4 - (Group/Division) – Exterior Enclosure/Division 3 Level 5 – Exterior Walls Level 6 – (Assembly) – CIP Concrete Walls Assembly includes these detail items: Concrete Construction Joints Waterstop Formwork Placement Reinforcing Embedded Items Strip Forms Finish Cure

In the example above, the Level 3 items do not support any given process and therefore they are assigned to “General” at Level 2. This same rationale applies whenever a WBS value at any level is not specific to any given WBS element at the higher (parent) level. If the element cannot be specifically assigned to a unique element at the higher level, it is assigned to the “General” value at the higher level. Another way to determine whether an element belongs to a specific element at a higher level is to evaluate whether or not the lower level element is required if the higher level element is deleted. If the lower level element is still required (even though it may be downsized), it should be assigned to the “General” WBS value at the higher

2-6 Chapter 2 Inputs to Estimating Process level. Conversely, if the lower level element is no longer required if the higher level element is eliminated, it should be assigned specifically to the corresponding higher element.

An example WBS for typical wastewater facilities can be discerned in the Example Cost Estimating Output Reports included as Attachments 4-1 and referenced in Chapter 4 of this Manual. Level 5 (Work Package) and Level 6 (Assembly) WBS values, organized by CSI specification division for use on all types of DEP projects are included in Attachment 2-1 of this Manual.

WBS Development by Deliverable Milestone and Estimate Class Table 2-1 provides a summary of the minimum and desirable level of the WBS that must be developed for each cost estimate at each delivery milestone. The minimum and desirable levels of the WBS reflect the range of scope definition that may be available at each estimating interval. Levels 1 through 3 of the WBS should be defined by the engineer of record while levels 4 and 5 can be developed jointly by the engineer and the estimating team with the engineer likely providing the initial definition and the estimating team verifying this information. Level 6, and the detailed estimate line items below Level 6, are defined and generated by the estimating team.

Project Scope

To ensure that the estimate accurately includes all elements of the approved project scope, the design team shall transmit a project scope definition package to the estimating team at each estimating milestone. The project scope definition package shall include, at a minimum, the following documents:

• WBS • Scope Documents (Reports, Memos, Drawings, Specifications, etc.) • Gap Analysis • Scope Change Log Work Breakdown Structure The WBS will be used by the engineering team to communicate a detailed itemized scope of the overall project to the estimating team. This is a particularly valuable tool to communicate scope shown and scope not shown. Often the engineer has an understanding of the scope of the project beyond what has been

2-7 Cost Estimating Manual June 2008 documented to date via the planning documents or the design drawings and specifications. On the other hand, the estimator’s understanding of the scope is somewhat limited to what is shown in the physical documents.

The estimating team will use the WBS transmitted by the engineer to structure the development and pre- sentation of the cost estimate. The estimating team will develop line item costs at the lowest level available in the WBS for each area. Depending on what level this is, the line item estimate could be based on results of parametric modeling (e.g. Level 2), estimated allocations (Level 1, 2, 3, or 4), or quantities shown or assumed (e.g. Level 6). The WBS should be as detailed as possible based on the engineer’s understanding of the ultimate project scope. The more detailed the WBS can be developed, the more powerful a tool it will be to the estimating team to allocate costs to the project, and the more valuable to the engineer in reviewing the estimate. As estimates are developed through the life cycle and additional scope is shown, costs associated with unquantified items will shift from allocations to more detailed (and correspondingly more accurate) take-offs.

Scope Definition Project scope definition is the most critical element in successful cost estimating. A minimum level of scope definition is required for each AACE Estimating Class. If the necessary scope definition is not provided at each milestone, the estimating team can not develop the associated class of estimate with the expected range of accuracy. The BEDC has developed a summary of the scope requirements for each deliverable milestone and associated AACE Estimating Class (See Attachment 2-2). The table is a significant expansion of Figure 4 in the AACE Recommended Practice No. 18R-97 (see page 8 of Attachment 1-1) tailored largely to the municipal water and wastewater industries. The engineer is required to review the content table and ensure that as many items as possible are included with each associated deliverable. Areas that could not be developed due to lack of information shall be flagged to the estimating team and should be a focus of the Gap Analysis described in the next section.

In any project, certain elements of the project will have the most significant effect on the final construction cost. As a rule of thumb, about 20% of the elements of a project can comprise 80% of the total cost. These elements or “cost drivers” should be identified as early in the project life cycle as possible and the design team should focus progress on design development based on the key cost drivers. This will improve the expected accuracy of the cost estimates at early stages of project development. In general, the content requirements for each class of estimate shown in Attachment 2-2 of this Manual are intended to capture the key cost drivers at early stages of project development.

2-8 Chapter 2 Inputs to Estimating Process

Cost drivers vary depending on the type of project and the project-specific scope. For water and wastewater treatment plant work, key cost drivers in early stages of project development typically include the following:

Table 2-2 Key Cost Drivers in Early Project Development Es t i m a t e Cl a s s Ke y Co s t Dr i v e r s Class 5 Capacity Site Selection Process Selection Class 4 Major Process Design Criteria Preliminary Site Plan Preliminary Geotechnical Information Preliminary Hydraulic Profile Preliminary Equipment List Preliminary Electrical Loads Preliminary Building, Structure, and Process Area Elevations, Plans and Major Sections (Archi- tectural and Mechanical Disciplines with approximately structural dimensions) Class 3 Final Geotechnical Plan Site Hazard Assessment Final Site Plan and Hydraulic Profile (Site Civil Works) Building and Process Area Plans and Major Sections Preliminary Concrete and Reinforcing Steel Quantities Mechanical Equipment and Valves Large Piping Electrical Equipment and Distribution (Single Line Drawings) Architectural Elevations Process and Instrumentation Drawings Construction Duration (General Conditions)

Gap Analysis A Gap Analysis is a systematic review and evaluation of the design documents against the approved scope. In performing the Gap Analysis, the current design deliverables are reviewed to assess the elements of the design scope that are and are not illustrated. The “gap” items convey scope elements known by the engineer to ultimately be required to complete the project but are not yet shown in the unfinished contract documents. The estimators use the Gap Analysis to develop as complete a price as possible by including unshown items identified in the Analysis. In general, the more comprehensive the Gap Analysis, the less uncertainty in the cost estimate.

The Gap Analysis is performed by the project design team. The lead designers should identify areas of the design that require further development, as well as elements that will be required, but have yet to be designed. As part of the Gap Analysis, the engineer should provide guidance on how to close the scope gap in the estimating process. Where possible, one or more of the following strategies should be used to close the identified scope gaps and communicate information to the estimating team:

2-9 Cost Estimating Manual June 2008

• Itemized list (with reference to drawing number) of scope items needed but not shown (e.g. structural footing drain pipe, pea gravel, geotextile, and observation manhole). • Hand mark-up on the documents delivered to the engineer with either sketches or notes of items that will be added in subsequent deliverable milestones and include a list of these items in the Gap Analysis narrative. • Hand mark-ups of existing facility drawings describing the change or elements to be replaced/ repaired. • Hand mark-ups of drawings of similar scope items from other projects showing modified dimensions and notes communicating the differences between the “go-by” design and the current project. (e.g. modify clarifier diameter from 50 to 70 feet and influent/effluent pipe diameter from 12 to 18-inch) • Provide cut sheets or other manufacturer’s information for major equipment and supplies and when available, vendor phone quotes.

Regardless of the estimate class being performed, the estimators should use the most detailed design information available at the time the estimate is being prepared. Prioritization of available design data to be used for input into the estimate (in descending order) is:

• Quantities from detailed engineering design documents for the current project including hand markups where possible • Quantities from “Go-by” detail designs from a similar project • Cost estimating relationships (capacity factors, equipment factors, etc.) Scope Change Log Each project team is required to maintain a scope change log throughout the design phase of the project. The scope change log is a tool to record all changes to the defined project scope. During the Design Phase, the Scope Change Log should maintain a record of any changes to the project that were either not defined or not anticipated at the initiation of the Design phase. Typically, the scope of a project during the Facility Planning Phase is captured in a Basis of Design Report (BODR). It is particularly important to document all scope items that were not accounted for in the previous estimate to help direct the estimating team to the new scope items. The most recent version of the Scope Change Log shall be submitted to the estimating team with each project scope definition package to assist in quickly identifying areas of change since the previous estimate was developed.

Project Risks

Each project team is required to maintain a Risk Register throughout the life cycle of the project. The Risk Register is a tool to record all identified project risks that could impact the budget or schedule of the project. The Register includes an estimate of the probability of occurrence and quantification of the potential schedule and/or budget impact of each identified risk. Additional detail on how the Risk Register should be incorporated into the cost estimate is included in Chapter 5 – Contingency.

2-10 Chapter 2 Inputs to Estimating Process

Project Schedule

Accurate, realistic construction schedules are a critical element for developing accurate cost estimates. In addition to facilitating calculation of time-related costs, an accurate schedule validates the time allotted for construction of the project in the bid documents. At a minimum, the project design team must provide the estimating team with significant milestones, anticipated contract dates, constraints, and phasing requirements for the project. The level of detail required in the project schedule to prepare a proper estimate increases with estimate class. A basic schedule of construction start, substantial completion and final completion is sufficient for preparation of a Class 5 estimate while a detailed critical path method Gantt schedule aligned to at least level 3 of the WBS is necessary to prepare a Class 1 estimate. The estimating and design team should work together to validate the durations and logic shown.

Pre-Estimate Meeting

Prior to development of a project estimate, a meeting shall be held with the key project stakeholders including the design team (Project Manager and technical leads, key subconsultants as appropriate), BEDC (Project Manager and a representative of the Cost Estimating Division), and the estimating team (lead estimators). The meeting should be held within approximately one week of the estimator’s receipt of the Scope Package from the engineer. The main purpose of the meeting is to ensure that the estimating team has a thorough understanding of the project scope. Key discussion items of the meeting shall include but not be limited to the following areas:

Design Team: • Review overall project scope • Review WBS • Review project scope not physically shown but necessary for the project (Gap Analysis) • Review specific areas of change since the previous estimate (recorded on Scope Change Log) • Review identified project risks (Risk Register) • Provide any historical cost data that may be relevant to project

Estimating Team: • Describe proposed estimating methodology and related assumptions • Describe proposed estimate WBS • Describe sources of data (labor, materials, escalations, etc.)

The meeting shall be documented in a set of meeting minutes highlighting key decisions and action items. All action items shall have an assigned responsible party and due date. The minutes shall be distributed to key project stakeholders.

Chapter 3 Estimate Preparation

Chapter 3 – Estimate Preparation This chapter describes the general approach to estimate preparation to be used for all BEDC cost estimating and includes subsections on the following subjects: • Estimating System Requirements • Estimating Methodology • Estimate Structure and Definitions • Estimating System Rates and Supporting Calculations • Estimate Inputs • Escalation of Construction Cost Inputs • Estimate Sections

Estimating System Requirements

All Class 4, 3, 2 and 1 estimates prepared for BEDC projects with an estimated construction cost of $25M or greater shall be produced using an estimating system with the minimum features listed below: • Multiple standard and custom reports using filter, sort, and subtotal features • Resource reports (labor, equipment, materials, etc.) • Variance reports able to compare estimates prepared at various stages of project development • On-screen review capability, including summary/drill-down features • Multiple resource rate tables • Update the entire estimate by changing a resource price or rate • Apply adjustment factors to portions of the estimate based on a selection criteria

Spreadsheet software may be used for Class 5 and 4 estimates and for supporting calculations of Class 3, 2, and 1 estimates. However, the body of Class 3, 2, and 1 estimates must be prepared using an estimating system with the capabilities listed above, as well as the capability of producing the reports listed in Chapter 4 of this Manual. Estimating systems used to prepare BEDC Class 3, 2 and 1 estimates shall be one of the following, or an approved equal: • Sage; Timberline Estimating Extended • MC2 (Management Computer Controls); ICE • Heavy Construction Systems Specialists (HCSS); Heavy Bid • Bid2Win Software • Hard Dollar • WinEstimator; WinEst

Approval to use any estimating system other than those listed above must be obtained in writing from the BEDC Cost Estimating Division.

3-1 Cost Estimating Manual June 2008

Estimates shall be submitted to the BEDC in hard-copy and electronic format. Electronic copies must provide BEDC Cost Estimating Division staff the ability to manipulate the estimate (sort, summarize, drill-down) as well as produce custom reports, but not necessarily revise the estimate.

Estimating Methodology

When submitting an estimate to BEDC, the estimator must identify the type of estimating methodology that will be used for the various components of the estimate and provide back-up material as required to support the accuracy of the method. There are a variety of industry standard techniques to develop estimates. The choice of technique is dictated largely by the level of scope definition and the end use of the estimate. In most estimates, multiple methodologies are used to account for the varying degrees of scope definition for different project elements. In general, top-down estimates are used in early stages of project development when less than about 15 to 20% of the total scope is defined and are typically limited in application to Class 5 and 4 estimates. Top-down estimates use rules of thumb, parametric models, analogies, or other cost estimating relationships (CERs) to estimate the total cost. These types of estimating methodologies can be highly inaccurate and proper levels of contingency must be applied to account for this estimating risk. Bottoms-up methods are characterized by a thorough, detailed analysis of scope and task components which can be “rolled-up” to produce an estimate of the entire project. This requires a detailed work breakdown structure and pricing of each work package that comprises the project. This method requires a higher level of scope definition and is typically reserved for Class 3, 2 and 1 estimates.

Definitions of the various estimating methods typically used in projects is listed below. Where available, definitions were quoted from the AACE Recommended Practice No. 10S-90 Cost Engineering Terminol- ogy. The methodologies are listed in the order of acceptable use based on scope definition. For example, Judgment, Gross Capacity-factored, and Parametric Models should only be used in early estimates (Class 5 or 4) while Detailed Unit Cost with Detailed Quantity Take-Offs are reserved for later estimates (Class 3, 2, and 1):

Judgment – Judgment is an estimating method based on historical experience with similar type facilities adjusted for known project complexities and size or capacity differences.

Gross Capacity-Factored – “A cost estimating method in which the cost of a new facility or facility component is derived from the cost of a similar item or facility of a known, but usually different capacity. In this method, the ratio of costs between two similar facilities is equal to the ration of the capacities taken to an exponential factor.” Capacity-factored estimating methods are typically based on a very limited amount of high level project definition such as average dry weather and peak wet weather flow (ADWF or PWWF) for a secondary wastewater treatment facility. A gross capacity-factored estimate could be based on a unit cost per capacity developed based on historical cost data of similar facilities adjusted for location and time.

3-2 Chapter 3 Estimate Preparation

Discipline-Factored – In early estimates, the various major trades of a project are sometimes calculated as a percentage of the total project costs. Discipline costs such as site civil works, electrical, instrumentation, and landscaping generally fall within a percent range of the total project. For example, instrumentation is typically in the range of 4 to 8% of the total project cost of a typical water treatment plant project while electrical systems are generally in the range of 8 to 15% of the total project costs.

Parametric Model – “In estimating practice, describes estimating algorithms or cost estimating relationships that are highly probabilistic in nature. Typical parametric algorithms include, but are not limited to, factoring techniques, gross unit costs, and cost models. Parametric estimates can be as accurate as definitive estimates.” Example inputs of a parametric model for a secondary clarifier cost model might include PWWF, maximum surface loading rate, and allowable water depth. Based on these high level inputs, the general dimensions of the facility can be estimated and when combined with unit costs of the elements, a parametric-based cost estimate can be developed.

Parametric models can also be used to price components of the project based on the output of preliminary design information. For example, after equipment requirements have been defined, power distribution can be estimated based on the total connected horsepower of the equipment; building lighting and receptacle/ branch wiring costs can be estimated based of the square footage of floor area of buildings.

Semi-Detailed Unit Costs with Assembly-Level Line Items – Both the takeoff and the estimate is done at the “assembly level” vs. the “line-item level”. This practice is typical of Class 4 estimates and for some elements of Class 3 estimates. In cases where portions of the design documents have not progressed to a point to allow detailed takeoff, and a “go-by” design from a similar project is not available, it may be necessary to use composite unit costs for certain elements of the projects. For example, if the only information available for a building is the square footage and the use of the building, it may be appropriate to use a “unit price factor”, which in the case of a building would be $/square foot of building. Factors such as this are known as “composite” prices as they include all the cost for the elements at the lower WBS levels. In this case, the composite square foot price for a building ($/square foot), includes the cost for all of the elements that make up a complete building (structural, architectural, plumbing, HVAC, electrical, etc.), and the estimate is done at WBS Level 2 only. As the design progresses, and more detail becomes available, it will be possible to include more detail in the estimate for WBS Levels 3 through 6, but by pricing at WBS Level 2 only, it is understood that the cost for all elements below this level are included in the composite price.

Detailed (Line Item) Unit Cost with Forced (Line Item) Quantity Take-Offs – If the class of estimate requires more detail than a capacity factor or composite price, “forced” takeoff, using cost estimating relationships, can be used to estimate the quantities at the lower WBS levels. For instance, cost estimating relationships for the average square feet of interior partition per square foot of building or the number of sprinkler heads per square foot of building can be used to estimate quantities for these elements, as well the remaining building elements. Another example of forced takeoff is pricing for a concrete wall - if the wall

3-3 Cost Estimating Manual June 2008 dimensions are available but the rebar details are not available, the formwork and concrete volume could be determined using line item detail and the rebar quantity could be determined using an average lbs/cy factor (pounds of rebar per cubic yard of concrete).

Detailed (Line Item) Unit Cost with Detailed (Line Item) Quantity Take-Offs – Complete detailed takeoff and line item estimating with 100% design drawings and documents.

Definition Assembly-Level and Detailed (Line-Item) Quantity Take-Offs –The difference between assembly-level and line-item detail as referenced in the discussion of estimating methodology above can be demonstrated by the example of cast-in-place concrete. At the assembly level, the takeoff quantity would be cubic yards, and the estimate detail would be manhours/labor per cubic yard, material per cubic yard, equipment cost per cubic yard, etc. At the detailed line level, takeoff quantities would include formwork, construction joints, waterstop, buy/place concrete, buy place reinforcing steel, embedded items, cure, etc.

The design and estimating team must work together to select the most appropriate estimating methodologies based on the scope definition and availability of historical cost data and parametric models, again keeping in mind that various methodologies can be used for various project elements or components. The team should strive to use the most advanced methodologies where possible to reduce estimating error. The estimating team is required to report on the estimating methodologies used in developing the estimate as part of the Basis of Estimate Report (See Chapter 4 –Estimate Outputs).

Estimate Structure and Definitions

In order to ensure consistency and to facilitate review and capture of historical cost data, all cost estimates prepared for BEDC Capital Projects must be prepared using a consistent format. This section describes the general organization of the estimate including required Cost Types, Fields (or Columns), Estimate Sections, and Line Item Coding. Cost Types Standard cost types/categories to be used in all estimates are: • Labor • Material • Equipment (Construction ) • Subcontracts • Other

3-4 Chapter 3 Estimate Preparation

These cost categories are typically the major column headings in all estimates, and all costs in the estimate must fall into one of these categories. Each cost type/category is defined below:

Labor – All craft and staff labor (both hourly and salaried employees) required to complete the project. Man-hours is the basic unit of measure for labor and regardless of how labor costs are estimated (by crew hours, man-months, man-weeks, etc.), total man-hours should also be calculated and included in the estimate.

Equipment – The cost for construction equipment utilized for construction of the project. Costs include: • Rental/depreciation • Maintenance/repair costs • Operating costs (fuel, oil, grease)

Labor to operate the equipment is not included in the equipment cost type. Labor for major maintenance/ repair of the equipment is included in the equipment cost. Labor for daily servicing should be included in the labor category, but as an indirect cost.

Material – All permanent and temporary material used in the project. Material is further subdivided into the following categories: • Permanent material – all material that becomes part of the completed facility other than process equipment • Process equipment – all equipment that becomes part of the completed facility and is shown on the equipment list • Temporary material – all material used and/or consumed during construction of the project that does not become part of the completed facility. Examples include plywood for concrete formwork, lumber for temporary scaffolding or walkways, and materials for temporary roadways.

Subcontracts – The cost of specialty work performed by subcontractors to the prime contractor. For all estimates prepared for BEDC, only subcontract items performed on an hourly or true unit-price basis should be included in the subcontract category. Prices in the subcontract column should be “all-in” prices, including subcontractor overhead and profit. All other costs (not procured on a true unit-price basis), even if performed by a subcontractor, should be estimated with the typical cost categories (labor, equipment, material, and other), but identified as a subcontracted item. This allows better analysis of on-site manpower levels, risk, escalation, markup, and other factors that may affect the total price of the project. Prices in the labor, equipment, material, and other cost type columns should not include subcontractor overhead and profit. Subcontractor overhead and profit can be added in the markup section of the estimate as described later in this chapter.

Other – All other costs that do not fit into one of the other cost categories (labor, equipment, materials, subcontracts).

3-5 Cost Estimating Manual June 2008

Fields/Columns in Estimates In addition to separate columns for the dollar amount for each of the cost types/categories noted in the previous section, the estimating system must contain additional fields (columns) to provide additional data to each line item estimate including quantities, how the line item is priced, and codes to allow the estimate to be sorted and summarized in various combinations. Not all columns will be used in any given report. Chapter 4 describes the standard estimate reports and which columns are included in each report. The fields and their functions are described below. The actual names of any given field may vary depending on the estimating system being used as long as the field performs the same function and provides the information listed. Field names in italics in the list below are “unit of measure” descriptions associated with a specific value field. The header for these fields may be combined with the header with the associated value field. For example the header for the “Estimated Productivity” value may be combined with the header for the “Productivity Unit” as long as the “Productivity Unit” is shown for each line item (e.g 250 cy/day or 0.15 mh/sf).

3-9 Cost Estimating Manual June 2008

Estimating System Rates and Supporting Calculations

This section describes the requirements of the various rate tables and supporting calculations that are part of the estimating system. Labor Productivity There are three basic methods for estimating labor costs: 1. Unit Price – Labor cost (dollar amount) per unit, not based on manhours and a labor rate. For example, the unit-price method for labor would use an historical price of $2.50/sf for an item, vs. using an historical production rate of 0.05 manhours per square foot, extended by a labor rate of $50.00 per manhour. The unit-price method for pricing labor shall not be used in estimates prepared for BEDC. 2. Manhour Pricing – Manhours per unit or unit per manhour; for example 5 manhours/each or 8 sf per manhour. 3. Crew Pricing – In this method, a crew is built up using multiple resources (labor and equipment), and extended against a production rate (example; cubic yards per hour, square feet per day, days per each, etc.).

Manhour pricing is typically used for labor-intensive work such as mechanical, electrical, concrete formwork, etc. Manhour pricing can performed the same way as crew pricing; by using a single labor resource as the crew. However, when using manhour pricing, a crew should still be used to account for a working foreman. This can be done by either adding a fraction foreman to a crew with a single journeyman or by composing the crew for the anticipated foreman ration. For example, with a journeyman-to-working foreman ratio of four-to-one, the crew could either consist of one journeyman and 0.25 foreman or four journeymen and one foreman.

Crew pricing is typically used for civil work and other equipment-intensive work because equipment resources can be assigned to the crew. In addition, crew pricing allows for the possibility of the need to augment the basic crew with additional resources. For example, it may be necessary to add a flagger to an excavation crew to account for traffic conditions around the excavation. In this case, the production rate can stay the same, but the manhours per unit and labor cost will go up since the crew is larger.

Another example is trucking associated with an excavation operation. The production rate is typically controlled by the capacity of the equipment performing the excavation, but the haul distance to the disposal affects the number of trucks required to support the operation (as the haul distance increases, more trucks are required). Labor Rates Manhour labor rates should be established by craft in the estimating system. Bare wages rates and fringe benefits should be obtained from published prevailing wages rates as covered by the New York State Labor Law Statutes 220 & 230. Prevailing Wage Rate tables are published for New York City and on a county-by- county basis in the remainder of the state. Labor rates should be fully-burdened to include payroll taxes and payroll-based insurance such as workers compensation. Craft-specific workers compensation rates should

3-10 Chapter 3 Estimate Preparation be used. For payroll tax and insurance rates that are employer-specific (based on experience factors), the default published rate should be used. An example labor rate calculations table is included as Attachment 3-1 to this Manual. Overtime Calculations Labor costs must be increased to account for planned and/or incidental overtime. Planned overtime occurs when the contractor plans to work other than a 40-hour work-week, (such as five 10-hour days per week, six 8-hour days per week, etc.) for some or all work activities. Incidental overtime occurs when crews must work past regularly scheduled work hours to finish a critical activity, such as a concrete pour. Overtime should be included in the estimate using add-on factors. (See the section titled “Estimate Sections” later in this chapter for instructions on using add-on factors.) The add-on calculation for overtime keys off the “Work Week” code assigned to each line item in the estimate.

Possible factors include: 42 hours/week – 5% incidental overtime 44 hours/week – 10% incidental overtime 48 hours/week – schedule six 8-hour days per week 50 hours/week – scheduled five 10-hour days per week 60 hours/week – scheduled six 10-hour days per week

Other overtime possibilities to consider would be 12-hour days. This situation might occur when supporting a 24-hr per day operation and changing crews twice per day (three, 8-hour shifts) is not feasible. Overtime factors should also take into account shift premiums such as 8-hours pay for 7 hours of work for swing or night shifts, or other premiums not included in the normal straight-time rates. These rules are normally identified in the union labor agreements. An example work week differential table for various overtime options is included as Attachment 3-2 to this Manual. Material Pricing Most construction materials may be grouped into three general categories: 1. Commercially-Available Commodities. Off-the-shelf items that are commercially available and not subject to significant regional variation in price such as: – Electrical commodities – Mechanical commodities – Building commodities 2. Location-Specific Commodities. Materials required in substantial quantities that are manufactured locally or regionally and subject to regional pricing/availability such as: – Concrete – Aggregates – Earthwork fill material – Rebar – Fabricated structural steel

3-11 Cost Estimating Manual June 2008

3. Project-Specific Equipment/Materials. Commonly large or custom (not “off-the-shelf”) items that are not manufactured locally and are subject to national or international availability such as: – Large fabricated pipe – Major Equipment – Large and specialty valves

The cost estimator is required to obtain telephone quotes or have in possession current invoices for all commercially available commodities. For location-specific and project-specific commodities, budgetary quotes from vendors are required. Decomposition of Composite Prices When composite unit prices are used, there should be a detailed estimate that calculates that unit price. The detailed estimate should document the assumptions for cost estimating relationships (for example lbs/ cy of rebar, sf of partitions per sf of floor area, etc.), as well as labor productivity, labor rates, material pricing, etc. In addition, when using composite unit prices, the price should still be broken into the basic cost types (labor, equipment, materials, subcontracts, and other) as well as manhours. This allows the unit prices in the assembly to be adjusted for escalation, wage rates, and productivity. Equipment Rates (Construction) If actual equipment rental rates and operating costs are not available, rates should be established using the most current data from the Associated Equipment Distributors (AED) Green Book. When using hourly rates for equipment that will be assigned to a work activity continuously, the hourly rates should be calculated as the monthly rental rate divided by 173 hours per month (40 hours per week times 52 weeks per year divided by 12 months per year). Blue Book weekly, daily, and hourly rental rates should only be used when the equipment will be used for durations consistent with such rates. Equipment rate tables should be set up with separate categories for ownership and operating costs to allow adjustments and/or escalation for operating costs due the potential volatility of fuel costs.

Estimate Inputs

Attachment 3-3 summarizes estimator inputs for each class of estimate for the typical cost drivers in municipal water and wastewater work. These key cost drivers include the following: • Equipment (Attachment 3-3A) • Earthwork (Attachment 3-3B) • Structural Concrete (Attachment 3-3C) • Electrical (Attachment 3-3D) • Process Piping (Attachment 3-3E) • Indirect Costs (Attachment 3-3F)

3-12 Chapter 3 Estimate Preparation

The tables in Attachment 2-1 show the description of each assembly, the unit of measure, and the required input for estimate Classes 2, 3, and 4. For Class 5 estimates, assembly level detail is not typically used. Class 1 estimates will typically use line item level of detail. The “required input” column is based on the design information that is typically available at the stage of the project development that corresponds with that estimate class. Where the required input is less than what is required for complete detailed takeoff using the assembly, the estimator may either use a composite price as described above, or generate the required input using forced takeoffs.

Escalation of Construction Cost Inputs

Escalation of construction cost inputs shall be included in all estimates. The assumed escalation is considered an element of the base cost estimate and not contingency. Escalation contingency is added to account for the possibility that the amount of escalation included in the base estimate will be exceeded.

Due to the volatility of various key construction materials, labor and material escalation should be calculated independently. Base cost estimates should included current labor and material prices with escalation calculated and shown separately as outlined below. Escalation calculations are to be included in the Basis of Estimate Report (See Chapter 4 – Estimate Outputs). Material Escalation The base estimate should be prepared using current prices for all materials and supplies included in the estimate. As noted earlier in this chapter, all material items in the estimate shall be assigned to a material class that corresponds to its associated PPI (Producer Price Index) escalation index. Producer Price Index classifications are maintained by the U.S. Department of Labor, Bureau of Labor Statistics and are available on the Bureau’s website, http://www.bls.gov/ppi/.

Different classes of material that represent a significant portion of the estimate may be subject to different market volatility and should be escalated using different rates. As part of this analysis, a material resource report by material class should be prepared and included with the estimate backup. Materials for which a specific escalation index is not available and are not a significant portion of the total material cost, may be assigned to a general escalation index, as long as a minimum of 80% of the total material cost in the estimate is assigned to a specific escalation index. Escalation for materials shall be based on data from a recognized provider of pricing data, such as Global Insight, or a similar service acceptable to the BEDC Cost Estimating Division. Forecast data must be updated at least annually but preferably quarterly, especially for critical materials. Updates shall be obtained to correspond with the anticipated duration of the project or for the period in which the materials are expected to be purchased by the contractor.

Material escalation shall also be analyzed using the proposed construction schedule. Different material and equipment items may require different escalation factors, depending on the anticipated purchase date. For instance, long-lead time specialty equipment will typically be purchased by the contractor shortly after

3-13 Cost Estimating Manual June 2008 receiving a Notice to Proceed. In this case, the estimated cost for the equipment does not need to be escalated past this date. Other materials may be subject to escalation throughout the duration of the project. For example, ready-mix concrete prices are typically subject to escalation at least annually, even if the contractor has committed to the entire concrete required for the work at the beginning of the project.

Material escalation shall be shown as separate line items on the estimate summary sheet, one line per escalation percentage, and the supporting calculations shall be included in the Basis of Estimate Report (see Chapter 4 – Estimate Outputs). Labor Escalation If available, labor rates should be escalated based on future increases included in the appropriate union labor agreements. If this information is not available or if contracts will expire prior to the scheduled end of the project, forecasts of labor rate increases prepared by a recognized industry forecast service (e.g Global Insight) should be used. Escalation should be based on an estimate of the number of manhours that will be expended during each wage period, typically annually.

Labor escalation shall be shown as a separate line item on the estimate summary sheet and the supporting calculations shall be included in the Basis of Estimate document (see Chapter 4 – Estimate Outputs). Escalating Composite Prices Where the estimate, or portions of the estimate, are not prepared at the line item detail level (for early estimates based on factoring or composite unit prices only), escalation should be calculated by decompos- ing the price to the same labor and material components that correspond to the escalation factors used in detail line item estimates. Completed estimates from historical projects should be used to facilitate the decomposition of the prices. A similar method should be used for escalating historical composite prices to current pricing.

Estimate Sections

All estimates should be structured with separate sections for each of the following major cost classifications: 1. Direct Costs 2. Indirect Project Costs 3. Add-ons 4. Contractor Markup 5. Contractor Bonds/Insurance 6. Project Contingency

3-14 Chapter 3 Estimate Preparation

Definitions for each of these cost classifications are shown below. Direct Costs Per AACE Recommended Practice 10S-90, direct costs are: “Costs of completing work that are directly attributable to its performance and are necessary for its completion. 1) In construction: the cost of installed equipment, material, labor and supervision directly or immediately involved in the physical construction of the permanent facility.”

Direct costs include all craft labor extending from the working foreman level down, that are directly associated with the physical work activity. Non-working craft supervision above the working foreman level (general foreman, master mechanics, shop stewards, superintendents, etc.) and all other staff supervision should be included in indirect project costs.

All permanent materials (materials that become part of the completed facility/project) are included in direct costs. In addition, temporary materials/supplies that are directly associated with a physical work item are included in direct costs. Examples of temporary materials/supplies that are included in direct costs include: • Materials/supplies for concrete formwork • Concrete curing compound • Lumber and structural steel used for temporary supports and falsework • Shoring for a structure excavation and recovered when no longer needed

Temporary materials and supplies that are not directly associated with a physical work item are included in indirect project costs. Examples include: • Scaffolding/walkways used by all crafts for various work items • Temporary enclosures and heating for all crafts for various work items • Materials for a temporary bridge constructed for access to the site

Construction equipment that can be directly attributed to the physical work and assigned to the crew is considered a direct cost. Examples of equipment that should be in included in direct costs include: • Excavating equipment • Cranes assigned directly to a specific crew and used for a specific work activity • Compressors assigned to an individual crew

Examples of equipment that should be included in indirect project costs are: • Forklifts at a common staging facility that supports all work activities • Cranes (fixed and mobile) that support multiples crafts and work activities • Flatbed trucks used for general purposes • Centralized compressed air systems • Centralized temporary power facilities

3-15 Cost Estimating Manual June 2008

Indirect Project Costs AACE Recommended Practice 10S-90 defines indirect costs as; “Cost not directly attributable to the completion of an activity.” In construction, all cost which do not become a final part of the installation, but which are required for the orderly completion of the installation and may include, but are not limited to, field adminis- tration, direct supervision, capital tools, startup costs, etc.” Indirect project costs are sometimes referred to as “general conditions costs”, “general expense costs”, “field overhead costs”, etc. For consistency, these costs should always be identified as “indirect project costs” in estimates prepared for BEDC.

Indirect project costs cannot be allocated to physical work items as they are either not related to the overall volume of work or cannot logically be allocated to any one physical work item. Essentially they are all project-related costs (other than bonds and insurance) that cannot be attributed directly to a physical work activity and generally include: • Mobilization/demobilization • Job-site staff (management, engineering, supervision, quality control, safety, support, etc.) • Temporary facilities and structures (offices, warehouses, safety/first-aid, tool sheds, fuel/repair facilities, etc.) • Temporary support facilities and utilities (barricades/fencing, parking/roadways, storage yards, signs, scaffolding, enclosures, etc.) • Temporary utilities (telephone, water, power, compressed air) • Job office expenses • Finance expenses

Not all indirect project costs will be incurred/expended at the project site. Depending on the size of the project and the contractor’s organization, some project-related functions may be performed at the contractor’s home office (e.g. project controls, change order estimating, project accounting, etc.). Even though these functions are performed at the home office, since they are directly related to the project, they are still considered project-related costs and should be included in the estimate as indirect project costs.

Many indirect costs are one-time costs (mobilization/demobilization) or strictly time-related costs (e.g. rent of office trailers or security guards) and are independent of the volume of work performed during any given period. A comprehensive checklist of all potential indirect project costs to be included in the estimate can be found in Attachment 3-4 of this Manual.

Some indirect costs are very easily calculated as percentages of other costs and are therefore included in the “Add-ons” section of the estimate summary.

3-16 Chapter 3 Estimate Preparation

Add-Ons Add-ons are used in estimates to calculate costs of items that are typically a percentage of other costs. Sales tax as a percentage of materials in an example. Other examples include: • Small tools and supplies as a % of labor or as a dollar per manhour rate • Overtime as a percentage of labor cost • Subcontractor markup • Escalation

Add-ons are useful because they automatically recalculate the amount of the add-on if the cost on which it was based changed. They also allow quick recalculation of an estimate if the rate associated with the add-on changes (escalation increased from 6% to 8% for instance).

Add-ons can also be used to calculate contractor markup/profit, as well as bond, and revenue-related insurance costs. However, these costs should be shown in their respective sections and not in the add-ons section of the estimate summary. Contractor Markup An amount included in the contractor’s bid price in addition to all project-related direct and indirect costs to account for profit/fee and to cover a portion of the company’s home office overhead. Contractor Bonds/Insurance This estimate section includes the cost to provide payment and performance bonds as well as the revenue- based insurance (typically builders risk and general liability insurance). Worker’s compensation insurance should be included in the labor rates. Contingency Estimating contingency is included as a separate chapter to this Manual (Chapter 5 – Contingency).

Attachment 3-3A Equipment In process plants, equipment is one of the most significant cost drivers and must therefore be identified and defined early in the design phase. In addition to being identified on the drawings, equipment must be defined using the followings: • Equipment List • Equipment Specifications

Equipment List

The equipment list should be started no later than the Class 4 estimate phase and updated as required throughout the remainder of design. At a minimum, the following equipment must be included on the equipment list: • All equipment shown on the Process Flow Diagrams and Process and Instrumentation Diagrams • All valves of >6-inches in diameter, gates, and meters • All equipment shown on the electrical Single-Line Diagrams • All equipment shown on HVAC schematics

The equipment list should include the item title, type of equipment, installation location, equipment number (from P&ID) drive type (rotating equipment), actuator type (for valves and gates) power requirements, key design criteria (size, dimensions, capacity, etc.), specification section, and P&ID Reference Sheet.

Minimum requirements for the Equipment List and Specifications for all equipment by estimate class are shown in the table below:

Attachment 3-3B Earthwork

General

Depending on the particular scope of the project, earthwork can be a major cost driver in construction. Be- cause of the wide range of existing site conditions, soil types, groundwater, staging/phasing requirements, and construction methods/equipment, earthwork is also a major source of variability in estimates. In addition, due to the potential for encountering unknown or unanticipated conditions, even after geotechnical investigations have been completed, earthwork represents a major risk factor.

Major Earthwork Work Packages

Work packages within the general “earthwork” classification can be grouped into three categories: • Mass Excavation & Fill/Site Preparation/Overlot Grading • Major Structure Excavation and Backfill (per structure) • Other (roadways, sitework finishes, etc.)

As the majority of the cost will typically be in the first two categories for treatment plant work, this section focuses on those categories only.

The “Mass Excavation/Site Preparation” work package includes all work required to adjust the site elevations to approximate final grade (or lower if structure excavation will be wasted on site). “Major Structure Excavation and Backfill” includes the excavation/backfill specific to a given structure or area after the mass excavation has been performed. Excavation and backfill specific to other project elements (pipe, ductbank, small structures, etc) is included with each structure or element.

Excavation Production Table

To facilitate estimate review, an Excavation Production Table should be completed and included in the Basis of Estimate document for all major excavation estimates. The Excavation Production Table summarizes the quantities determined by the detailed excavation takeoff and documents the assumptions (method, crew, and productivity) for the major elements of the excavation estimate: • Excavate • Load and Haul • Place and Compact

Line items in the Excavation Production Table should be structured to allow the reviewer to determine where the excavation occurs, where the material is transported, excavation methods, placement/compaction methods, and associated production rates. Total quantity should be based on the amount to be excavated and/or fill required. Individual line item within the table represent quantities for separate areas or

2 Attachment 3-3 Estimator Inputs structures that will use the same methods, crew, production rates, haul distances, disposal methods, etc. For example, material that will be moved to a temporary stockpile location should be on a separate line item than material that will go straight to a permanent fill location, or be hauled to an offsite disposal area. Only quantities that use the same method, crew, disposition, and production rates should be on the same line.

The combination of the various methods for these elements will depend on a number of factors, including: • Distance between excavation site and spoil/stockpile site • Timing of excavation vs. backfill • Material type • Equipment availability

If material must disposed off-site, any required disposal/tipping fee per cubic yard or ton should be shown for each affected line. If the fee is on a per ton basis, the conversion from cubic yards should also be shown in this column.

Depending on the conditions, not all of the elements may be applicable to a given operation. For example, if the excavation for a small structure is performed by a backhoe that is able to simply sidecast the material which is later used for backfill at the same location, there may not be a load/haul component. In other cases, the excavator may be able to place the material directly in the hauler such that a separate loading operation is not required.

In cases where all three elements (excavate, load/haul, place/compact) are performed simultaneously and at the same rate, this could theoretically be considered as a single crew. In this case, individual crew members and equipment should still be assigned to each element to facilitate production analysis and review. Only in cases where the same piece of equipment performs multiple elements (such as a scraper operation) should the crews be combined.

Site conditions may require additional processing of the material in addition to the three typical operations (excavate, load/haul, place/compact). Additional operations may include: • Screening • Drill/Blast • Soil Conditioning • Disking/Drying • Mixing • Shoring / Soil Stabilization

These additional operations should be shown as separate line items in the Excavation Production Table, and since they represent “double handling” of the material, the quantities will be in addition to typical excavation quantities.

3 Attachment 3-3 Estimator Inputs

Support Operations

Many other items that are not necessarily driven by the excavation quantities must also be included in the earthwork estimate. These include: • Erosion Control • Haul road development • Haul road maintenance • Dust control • Stockpile maintenance • Weed control • Dewatering

Since these items may not be “quantity-driven” (not proportional to the excavation quantities) they will typically not be included in a unit price for excavation, and are not included in the Excavation Production Table.

Structure Excavation Table

A Structure Excavation Table should be created for all major structure excavation and backfill to document the assumptions made for quantity takeoffs (excavation depth, side slopes, side clearance, etc.), and to serve as a checklist to ensure all required elements have been included. For simply-shaped excavations, the table may also be used to perform the quantity takeoff. Quantities and assumptions generated by the Structure Excavation Table should be posted to the Excavation Production Table.

Quantity Determination for Each Estimate Class

Since earthwork represents a major cost driver, estimates should be prepared using the most detailed information available. The minimum level of detail that should be used for each estimate class is summarized below.

Class 5 – Earthwork quantities can be assumed using a “go-by” design, historical data, or may be included in the capacity factor used to price the work.

Class 4 – Major earthwork quantities may be determined using the preliminary site grading and facility layout plans coupled with the hydraulic profile.

Class 3 – Major earthwork quantities can typically be finalized at this point. Preliminary quantities for other earthwork packages (roads, finishes) should be estimated at least at the assembly level.

Class 1/2 – All earthwork quantities should be finalized in the Class 2 estimate.

Attachment 3-3C Structural Concrete Structural concrete typically represents a significant cost driver for water and wastewater facilities. The percentage of the total cost associated with concrete will vary depending on the particular project scope. Where concrete will be a significant cost driver, the estimate should be based on the most detailed information available. Whenever possible, estimates for structural concrete should be based on detailed takeoffs, either from the design documents from the actual project, or documents from a similar facility (“go-by” design) adjusted to approximate the actual project.

Forced Takeoff for Structural Concrete

If details are not available, either from the design documents or “go-by” design documents, it may be necessary to use “forced takeoff” (cost estimating relationships) to calculate concrete quantities. Typically, there are two levels of forced takeoff: • Volume of concrete based on a project design parameter • Quantity of concrete-related components based on concrete volume

Components for Structural Concrete

Estimates done at line-item detail level should contain at a minimum the following components: • Concrete volume (cy) • Formwork (sf) • Shoring (cf) • Finishing (sf) • Reinforcing (tons) • Accessories – Waterstop (lf) – Embedded misc. metal, including anchor bolts (lbs) – Expansion/contraction joints (lf) – Vapor Barrier (sf) – Hardner / Sealer (sf) – Formliners – Admixtures – Keyways – Blockouts In addition to the components listed above, line items should be identified by the following categories: • Concrete by : – Strength/mix design – Placement method

• Buggy • Truck • Crane • Pumped – Assembly • Walls – Straight – Circular – Battered • Slab on Grade • Elevated Slabs – Suspended Formed – Slab on Metal Deck • Beams (if not integral with slabs) • Columns – Square – Round • Footings – Continuous – Pad • Equipment Pads • Stairs (cast in place concrete) • Curbs and Miscellaneous • Formwork by type – Walls • Gang • Handset • Straight • Circular • Battered – Elevated slabs – Slab on Grade • <12” • 12” to 24” • >24” (Raft Type) – Columns • Square • Round

6 Attachment 3-3 Estimator Inputs

– Beams (integral or non-integral) – Footings • Continuous • Pad – Stairs – Equipment pads – Curbs • Finishing by type – Horizontal • Float • Trowel – Vertical • Point and Patch • Sack Rub

Composite Prices

When details are not available to perform takeoff at the assembly or component level, composite prices may be generated. Composite prices per cubic yard of concrete are generated by using an average quantity for the various components, and pricing the average quantities with current labor and material rates. This composite cost is then extended against the concrete quantity to obtain the total cost.

Typical composite prices include: • Cost per cubic yard for all structural concrete, when quantities by assembly are not available. • Cost per cubic yard by assembly type.

Composite prices should be generated to allow calculation of all cost types (labor, permanent material, equipment, supplies, etc.) and man-hours. Also, because of the possibility of large swings in material prices, concrete and reinforcing steel should be itemized separately for all estimates (i.e., even though a composite price is used to generate costs, the quantity and cost of reinforcing steel should be broken out separately). If composite prices are used, the supporting calculations and pricing should be included in the Basis of Estimate documents.

Assemblies

In order to facilitate scope and pricing reviews, concrete takeoffs and estimates should be performed and summarized by the following assemblies (WBS Level 4). Small/insignificant quantities may be summarized in the “other” assembly category. Large/significant quantities may require an additional designation. Total and unit costs should be shown at the assembly level, with cubic yards as the unit.

Takeoff/Estimating Requirements by Estimate Class

Target requirements for concrete takeoff and pricing are listed below for each estimate class. These are the targeted requirements and whenever possible, revert to the following preferences: • Detailed takeoff of all components (DTO) • Detailed takeoff of volume and formwork; forced takeoff (FTO) of remaining components based on concrete volume

Attachment 3-3D Electrical Electrical systems typically represent a significant cost in treatment plant construction. Because the electrical design is highly dependent on the process design and especially the equipment selection, the input available for estimating the electrical systems typically lags behind other disciplines. Accordingly, early estimates must rely more heavily on cost estimating relationships and/or “go-by” designs. Electrical work in treatment plants generally falls into three major categories: • Process-related systems that supply power to the major process equipment • Building and site services (lighting, receptacle power, etc.) • Communication and security systems

Horsepower of the process equipment is the cost driver for the process-related systems while the square footage of the buildings and facilities drives the other systems. Minimum required input and the associated estimating methodology for each class of estimate are listed below. See Appendix 2-1 for the input requirements for electrical assemblies. Class 5 If “go-by” design information is not available for the Class 5 estimate, electrical systems may either be included in the capacity factor, or based on a cost estimating relationship (typically equipment-factored based on the anticipated horsepower of the equipment) and the square footage of the facilities. Class 4 At Class 4, the P&ID drawings are “advanced” and should show all process equipment and the preliminary equipment list should be available including all horsepower requirements. From this information, the total power requirements for each process area may be determined and cost estimating relationships or “go-by” design of electrical systems can be used for estimating purposes. In addition, the preliminary site plan and architectural floor plans are available for forced takeoffs of building and site electrical services (e.g. sight lighting). Class 3 At Class 3, the electrical single-line diagrams are advanced and any electrical systems not shown on the single-line diagrams should be noted in the Gap Analysis provided by the design team. Together with the mechanical, structural, and architectural floor plans, all of the process-related electrical systems and the majority of the remaining electrical systems can be estimated at line item detail by using assemblies (see Appendix for a list of assemblies). For the building/site services, and communications/security systems, forced takeoff on a square foot basis may be required to generate quantities for the assemblies. Class 2 and 1 At Class 2, all systems have at least a preliminary design available and all electrical should be estimated at a line-item level of detail with only minor adjustments required for the class 1 estimate.

Attachment 3-3E Process Piping Process piping is normally a significant cost item in treatment plant work and includes all piping shown on the P&ID drawings. It does not include plumbing (domestic water and sanitary waste piping). The majority of the cost for process piping will be around the process equipment as this is where the majority of the valves, fittings, and in-line devices are located. Complete P&ID (Process and Instrumentation Diagram) drawings are essential for accurate piping estimates.

Piping takeoffs should be organized and identified by system, service, and size within each process area. Process piping outside the battery limits of a given process area (typically identified as “yard piping”) should be included in the “General Site” area in the WBS.

Assemblies for process piping should include all valves and in-line devices as well as hangers, supports, and other ancillary items (nut/bolt sets, gaskets, fittings, etc.). Minimum required input and the associated estimating methodology for each class of estimate are listed below. Class 5 If “go-by” design information is not available for the Class 5 estimate, process piping may either be included in the capacity factor or based on a cost estimating relationship (typically equipment-factored based on the value or capacity of the equipment) in each process area. Class 4 At Class 4, the P&ID drawings are “advanced” and should show all process piping so takeoffs may be done from the P&ID drawings with estimated lengths and assumed fitting densities (number of elbows, tees, etc., per lineal foot of pipe). Any piping not shown on the P&ID drawings should be noted in the Gap Analysis provided by the design team. Class 3 P&ID drawings are complete at this point, so all process piping will be shown. In addition, most large diameter pipe will be shown on the mechanical plans and sections. Pipe not shown on the mechanical plans/sections may be estimated from the P&I drawings using the same methodology as for the Class 4 estimate. Class 2 AND 1 At Class 2, all large-bore process piping (4” diameter and greater) is shown on the mechanical drawings and complete takeoffs can be included in the estimate. Small-bore pipe (less than 4” diameter) may not be shown on the mechanical drawings so takeoff is performed using assumed routing, lengths, and fitting densities.

Attachment 3-3F Indirect Project Costs Indirect cost may be estimated as a percentage of direct cost for all projects with an estimated construction of less than $50M for all estimate classes and for all project greater than $50M for class 5 and 4 estimates. For projects greater than $50M or with construction schedules that exceed 24 months, a detailed estimate of Indirect Project Cost should be performed using the checklist included in Attachment 3-4.

Since many of the Indirect Project Costs are time-related, the anticipated construction schedule should be used when estimating these costs. Personnel costs represent a major portion of the time-related Indirect Project Cost, and the average and peak staff manpower on site also drives other costs such as office space requirements, relocation and per-diem cost, etc. On all projects over $50M, a personnel schedule should be included as part of the Basis of Estimate document. For each individual, the schedule should indicate: • Anticipated start date • Anticipated completion date • Relocation required (yes/no) • Per diem required (yes/no) • Vehicle (yes/no) • Cell phone (yes/no) • Personal computer (yes/no)

The personnel may be done in a spreadsheet or by other means, but should be capable of calculating the total months or weeks for each individual, and the average and peak manpower.

Basic Estimate Reports

It is imperative that estimating reports be delivered to BEDC in a consistent format to facilitate review by the BEDC Cost Estimating Division. This section describes the desired format of estimate submittals to BEDC. Each of the estimating reports to be submitted by the estimating team at each estimating interval is described below and examples of each are contained in Attachment 4-1 of this Manual.

1. Summary Reports – summarized to the following WBS Levels (one line per summary level): 1a. WBS Level 1 Summary Report (Attachment 4-1A) 1b. WBS Level 2 Summary Report (Attachment 4-1B) Summary reports should include the following columns: • WBS Level • Labor Manhours • ”Amount” columns for: – Labor – Equipment – Material – Subcontracts – Other – Total • Percentage of Total (optional)

2. Scope Review Reports 2a. Scope Review Report - organized by Assembly showing all cost types, summarized to WBS Level 5 (Work Package), sorted by Area/Process/System/Work Package/Assembly and with the following columns (See Attachment 4-1C):

• Sort Level (to delineate • Labor Cost/Unit • Subcontract Cost/Unit sort/subtotal levels) • Labor Amount • Subcontract Amount • Notes • Equipment Cost/Unit • Other Cost/Unit • Takeoff Quantity • Equipment Amount • Other Amount • Unit Of Measure • Material Cost/Unit • Total Cost/Unit • Labor Manhours • Material Amount • Total Amount

4-1 Estimate Output June 2008

2b. Scope Review Report - with Line Item Detail using same format as above with estimate line (See Attachment 4-1D). NOTE: this is an optional report to BEDC and only required if requested by the Cost Estimating Division. This report can be submitted as part of the estimate review package, or a single copy can be available at the scope review meeting with the project team. Alternately, this level of detail may be reviewed during the review meeting with a live copy of the estimate “on-screen” using a laptop computer and screened projection.

3. Labor/Productivity and Pricing Reports 3a. Labor/Productivity Detail Report Organized by Assembly. This report is used for review of content and labor productivity/pricing within assemblies (See Attachment 4-1E). The report is sorted by assembly with line item detail for the items within the assembly. Like assemblies are combined in this report (quantities and amounts for like assemblies are combined into a single assembly). Columns as shown below:

• Assembly/ • Estimated Productivity • Material Cost/Unit Database Level 2 • Labor Cost/Unit • Material Amount • Item Description • Labor Amount • Subcontract Cost/Unit • Database Level 3 • Equipment Cost/Unit • Subcontract Amount • Takeoff Quantity • Equipment Amount • Other Price • Unit Of Measure • Material Conversion Factor • Other Cost/Unit • Crew • Material Waste (yes/no) • Other Amount • Labor Manhours • Material Waste % • Total Cost/Unit • Base Productivity • Material Quantity • Total Amount • Productivity Adjustment • Material Price

3b. Labor/Productivity Detail Report (Item). This report is used for review of labor pricing, labor productivity, and material pricing of individual estimate line items (See Attachment 4-1F). The report is sorted by Database Level 3/Database Level 2 with like items combined (items of the same work scope and same production rate combined into a single line item; quantities and amounts represent the total of all like items). Columns as shown below:

• Database Level 2/3 • Labor Rate Table • Material Tax (yes/no) • Item Description • Labor Amount • Subcontract Cost/Unit • Takeoff Quantity • Equipment Cost/Unit • Subcontract Amount • Unit Of Measure • Equipment Amount • Other Price • Crew • Material Conversion Factor • Other Cost/Unit • Labor Manhours • Material Waste (yes/no) • Other Amount • Base Productivity • Material Waste % • Other Tax (yes/no) • Productivity Adjustment • Material Quantity • Total Cost/Unit • Estimated Productivity • Material Price • Total Amount

• Labor Cost/Unit • Material Cost/Unit • Labor Price • Material Amount

4-2 Chapter 4 Estimate Output

4. Labor and Equipment Resource Reports 4a. Labor Resource Report organized by labor classification (See Attachment 4-1G). One line per labor classification with columns for: • Description of Labor Classification • Manhours • Labor Amount ($) • Average $/Manhour Total labor amount for the report should be equal to the total labor amount on the summary section of the various estimate reports noted previously. Average $/Manhour for each labor classification should be compared to the labor rate listing in the basis of estimate report to make sure the rates are consistent.

4b. Equipment Resource Report organized by piece of equipment (See Attachment 4-1H). One line per piece of equipment with columns for: • Description of equipment • Total equipment hours • Equipment Amount ($) • Average $/Equipment-Hour The total equipment amount for the report should be equal to the total equipment amount on the summary section of the various estimate reports noted above. Average $/Equipment-Hour Manhour should be compared to the labor rate listing in the basis of estimate report to make sure the rates are consistent. In addition, this report may be used to make an “equipment adjustment”. This may be necessary when certain pieces of equipment may be required on the site, but not fully utilized. The hours for the piece of equipment may need to be adjusted to a “time-phased” basis in lieu of the total hours utilized in the estimate.

Basis of Estimate Report

In addition to the estimate reports noted above, all estimates prepared at each stage in the project development with a value over $25M shall include a comprehensive Basis of Estimate Report (BOE) Report. The Report must be prepared in accordance with AACE Recommend Practice 34R-05 Basis of Estimate as modified herein. A copy of the document is included as Attachment 4-2 of this Manual or may be obtained at http://www.aacei.org/tcm/. Specific requirements for BOE Reports prepared for BEDC are detailed below. In some cases, the recommendations in AACE 34R-05 have been adopted and quoted in whole.

The BOE Report communicates the rationale, assumptions, pricing sources, and other inputs to the estimating process used by the team in development of the cost estimate. This document consolidates information prepared from multiple sources which are used to establish the basis of the cost forecast. Each BOE Report shall address the topics, as applicable, described in this section. If there are no applicable items for the section, of if for any reason the section does not apply, the section heading should still be included in the document, and the text should read “NONE”, or “N/A” (not applicable).

4-3 Estimate Output June 2008

Project Scope Description Provide a brief narrative describing the major project components. The section should generally be limited to no more than one page.

Estimating Methodology Indicate the primary estimating methodology used to prepare the cost estimate. Where different methodologies were used for major elements of the estimate or different work packages, give a brief description of each, organized by WBS. Identify the percentages of the total direct cost wherein the quantities were determined by the various estimating methods. These percentages can be determined by running an estimate report sorted by the Quantity Source Code as defined in Chapter 3.

1) Detailed takeoff off design drawings 2) “Forced” takeoff from partially complete design drawings 3) Takeoff from a “go-by” design (design drawings from a previously-designed facility similar in size in nature) 4) Factored using a cost estimating relationship 5) Assumed by estimator (no drawings or cost estimating relationship available)

Estimate Classification Identify the AACE estimate classification for the entire estimate based on the quality of the design documents used to prepare the estimate and the estimating methods used. Where different elements of the estimate fall within different AACE classifications, the estimate should only be assigned to a given classification if at least 75% of the estimated cost is supported by scope definition and estimating methodologies falling within that classification. If the completed estimate does not meet the criteria for the AACE estimate class as further defined in this Manual required by the corresponding life-cycle stage, identify the reasons and/or justification why the estimate does not meet the specified class.

Design Basis Reference all documents provided to the estimating team to convey the scope of the project. As a minimum, the following documents should be referenced in the BOE and attachments provided where noted:

• Updated log of all reports, design drawings, specifications, equipments lists, and other design information used in preparing the estimate. Typically this list should be prepared and kept up to date by the design team. • Compare the required design content summarized in Attachment 2-2 (see Chapter 2) to the actual design content delivered to the estimating team. Include comments of the completeness and adequacy of the documents for the class of estimate proposed. • If material take-off’s (MTO’s) are provided to the estimating team, identify specifically who developed the MTO’s and the methodology used. Also a summary of these quantities as an attachment to the BOE. • Gap Analysis including disposition of the items by the estimating team (Attachment).

4-4 Chapter 4 Estimate Output

• Meeting minutes of the Pre-Estimate Preparation Meeting and any additional meetings held with the project team during estimate preparation and review. Planning Basis Include a brief description of the contracting and procurement plan/strategy provided to the estimating team by the project team. The plan should include any provisions for pre-purchase of equipment or materials by the Owner or Owner’s agent, use of specialized construction equipment, modularization, etc.

Identify key project milestones, both those supplied to the estimating team by other members of the project team and those assumed by the project team. If multiple contracts are to be awarded, the dates for all contracts should be included. At a minimum, key milestones should include the anticipated dates for:

• Advertisement • Bid Date • Notice of Award • Begin Mobilization • Specified Contractual Interim Milestones • Substantial Completion Date • Final Completion Date • Start and completion of major phases of the work • Startup/commissioning of major systems • Other significant milestones in the construction schedule

Document and discuss scheduling assumptions used in preparing the schedule and estimate including but not limited to:

• Work-week schedule (hour worked per day, days worked per week, shifts worked per day, etc.) • Planned use of overtime • Provision for “incidental” overtime • Constraints on “seasonal” work due to temperature, inclement weather, assumptions for lost work days due to inclement weather, etc. • Identify which key work activities will be affected by the above

Reference and attach a copy of the construction schedule used to estimate the work. The schedule provided to the estimating team with the project definition package for each estimate should be validated for logic and durations by the estimating team. List any recommended changes to the engineer’s proposed schedule based on the estimating effort.

4-5 Estimate Output June 2008

Cost Basis Identify and describe the cost basis, factors, and pricing sources for the following:

Material Pricing. Pricing sources for all major equipment and significant commodities shall be identified. Include a Bill of Material report sorted by the Material Source Code and Material Class. Include any quotes for major equipment and significant commodities in the attachments. Discuss calculation of freight costs for any materials where freight is not included in the base price. If desired, freight may be included as an add-on cost (see Chapter 3). Labor and Equipment Rates. Calculation sheet documenting all wage and equipment rates used including craft rates, crew mix, equipment rates, etc. Include a crew detail report to identify the crew mix and a rate table report. Include all items included in the rates. For labor include the base rate, fringes, payroll taxes, workers compensation and other insurance. For equipment, include rental/depreciation rate and hourly operating cost). Labor Productivity. Discuss source of labor productivity rates used in the estimate (source of database, historical data, etc.) and source and rationale for any adjustment factors applied for each major Work Package. Include an estimate report sorted by Work Package (WBS Level 5) and Productivity Table to identify and quantify productivity adjustments included in the estimate. Indirect Cost. Pricing source and methodology for estimating project indirect costs. If the indirect costs are calculated by percentage, provide the rationale and identify the source Taxes and Duties. Identify all taxes and duties, including their rate and basis, included in the estimate. Escalation. Describe indices used, basis for application, to what items they were applied and the method of calculation (including duration). Contractor Markup/Profit. Discuss the basis for the contractor markup/profit used in the estimate, including the influence of local market conditions. Other Factors. Identify any unusual pricing factors or external influence that may have a significant impact on the project that are not described elsewhere in the report. Examples include: • Currency exchange rate for equipment/materials purchased outside the country. If currency exchange rates were used to calculate portions of the estimate, list currency exchange fluctuations as a potential in the risk log. • Temporary surcharges • Price and productivity factors for an unusual location, restricted access, restricted work hours, etc.

Allowances Describe any allowances (per the definition below) included in the estimate, the amount of those allowances, and where they are included in the estimate. The definition of allowances from AACE 10S-90 and adopted by BEDC is as follows:

“Resources included in estimates to cover the cost of known but undefined requirements for an individual activity, work item, account or sub account. (6/07)” (emphasis added)

Do not include other items referenced in the allowance section of AACE RP 34-05 (material take-off allowance, overbuy allowances, congestion allowances, working allowances) as these do not fit the definition of allowances. These types of costs should be detailed in the cost section of the BOE document.

4-6 Chapter 4 Estimate Output

Assumptions Any assumptions made by the estimator but not documented elsewhere in the estimate basis should be included in this section. Assumptions should be grouped into two basic categories:

1. Scope. Assumptions made by the estimator where the design documents did not provide adequate detail to do a proper quantity take-off, site conditions not defined, etc. 2. Pricing. Assumptions that would affect pricing of materials, availability of labor, etc. Examples include adequate source of fill material located within 50 miles of the project site or adequate supply of labor without supplementing with resources from other areas. Add-Ons Include a report to show how all add-ons (see Chapter 3) have been applied (basis, range, etc.).

Exclusions In this section, the estimator should document all potential items of cost which a reviewer might associate with the project, but for which no costs have been included in the estimate. Asbestos abatement, removal of hazardous wastes, acquisition of land, taxes, financing costs, licensing costs, etc., are examples of potential items that need to be identified.

Exceptions The estimator should identify any anomalies or variances to the BEDC’s standard estimating practices.

Risks and Opportunities Any areas of the estimate containing significant risk or opportunity should be identified and itemized in this section. As a minimum, the project risk log should be attached to the BOE. For projects that require a complete risk analysis, the summary report should be attached to the BOE. See Chapter 5 – Contingency for additional details on estimating project risks.

Contingencies The methods used to determine the contingency amount should be described.

Reconciliation All BOE documents should reference and include as an attachment a reconciliation report WBS 2 level showing the previous estimate (estimate prepared at the previous stage of the project life cycle), the current estimate and the difference by cost type (labor, equipment, material, other, total). Additional reports at a lower WBS level may be necessary to highlight certain changes. Provide an overview of the major difference between the current estimate and the last-published estimate.

If there are major differences between the current estimate, and the previous estimate, a detailed reconciliation may be necessary. Detailed reconciliations should be organized by WBS and cover all aspects of project documentation (cost estimate, basis of estimate, schedule, and risks). In general, reconciliation should

4-7 Estimate Output June 2008 recognize or highlight specific changes in scope, basis of estimate, schedule, and risks. Identify the cost impact due to scope changes, pricing updates, labor productivity adjustments, estimate refinements, etc.

Estimate Quality Assurance Identify all estimate reviews that have taken place to date and any additional reviews that are proposed to take place subsequent to delivery to BEDC.

Estimating Team Include a list of the estimator responsible for each Work Package (WBS Level 5) in the estimate.

AACE International Recommended Practice No. 34R-05 BASIS OF ESTIMATE TCM Framework: 7.3 – Cost Estimating and Budgeting

May 2, 2007

PURPOSE

AACE International’s Total Cost Management (TCM) Framework identifies a basis of estimate (BOE) document as a required component of a cost estimate. As a Recommended Practice (RP) of AACE International, the template outlined in the following sections provides guidelines for the structure and content of a cost basis of estimate.

In the TCM Framework, the BOE is characterized as the one deliverable that defines the scope of the project, and ultimately becomes the basis for change management. When prepared correctly, any person with capital project experience can use the BOE to understand and assess the estimate, independent of any other supporting documentation. A well-written BOE achieves those goals by clearly and concisely stating the purpose of the estimate being prepared (i.e. cost study, project options, funding, etc.), the project scope, pricing basis, allowances, assumptions, exclusions, cost risks and opportunities, and any deviations from standard practices. In addition the BOE is a documented record of pertinent communications that have occurred and agreements that have been made between the estimator and other project stakeholders.

A well prepared basis of estimate will:

• Document the overall project scope. • Communicate the estimator’s knowledge of the project by demonstrating an understanding of scope and schedule as it relates to cost. • Alert the project team to potential cost risks and opportunities. • Provide a record of key communications made during estimate preparation. • Provide a record of all documents used to prepare the estimate. • Act as a source of support during dispute resolutions. • Establish the initial baseline for scope, quantities and cost for use in cost trending throughout the project. • Provide the historical relationships between estimates throughout the project lifecycle. • Facilitate the review and validation of the cost estimate. This RP is intended to be a guideline, not a standard. It is understood that not all organizations that prepare estimates employ the same processes and practices, and therefore, may opt to use this information either in part or in its entirety.

RECOMMENDED PRACTICE

The primary intent of this RP is to provide a guideline for the topics and contents to be included in typical BOE. However, before describing the template contents there are a few points of significance worth noting:

• Be factually complete, but be concise. • Be able to support your facts and findings. • Identify estimating team members and their roles. • Describe the tools, techniques, estimating methodology, and data used to develop the cost estimate. • Identify other projects that were referenced or benchmarked during estimate preparation. • Develop the cost estimate and the BOE concurrently. • The BOE establishes the context of the estimate, and supports review and validation.

Basis of Estimate 2 of 6

May 2, 2007 • Qualify any rates or factors that are referenced either in the estimate or BOE; e.g. productivity can be expressed as either units/time (linear feet/hour) or time/units (hours/linear foot). The following describes the suggested topics and contents included in a typical BOE.

Purpose In this initial section of a basis of estimate, the estimator should provide a brief and concise description for the total project. The type of project should be identified (i.e., new facilities, addition to existing, revamp of existing, etc.), as well as the type and capacity of the process units, the location of the facility, and the overall timing of the project.

Project Scope Description This section of the estimate basis should be organized to correspond with the project’s work breakdown structure (i.e., plant, building, floor, etc.). A semi-detailed description of the scope of work should be provided for each major segment of the project. Identify any major pieces of process equipment or components. It’s also good practice to indicate the primary trades that will be involved with the project. Be as thorough as necessary, without being overly descriptive, so as to adequately explain the scope of work being estimated.

Methodology The BOE should indicate the primary estimating methodology used to prepare the cost estimate. This should include documentation of the use of cost resources, historical data and project benchmarking. Documenting the level of effort or man-hours used in preparation of the estimate may also be helpful.

Estimate Classification The AACE International estimate classification should be identified, along with reasons or justification used in the selection of the estimate classification.

Design Basis Company standards will typically specify the technical and project information required for the classification of the estimate that is being prepared. In this section, the estimator will identify the types and status of engineering and design deliverables that were provided to prepare the estimate including any design basis assumptions. Two attachments to the estimate basis should be referenced: 1) an estimate deliverables checklist that is aligned with the company’s standard project process; and 2) a listing of all engineering drawings (including revision number and date), a well as other design information, such as specifications, equipment lists, units of measure (imperial vs. metric), etc.

In addition it may be useful to document specific quantity metrics for particular projects, such as overall excavation and backfill quantities, overall concrete volumes, overall piping quantities, etc. These may be organized by facilities, process train or manufacturing unit.

If material take-off’s (MTO’s) are provided to the estimator, identify specifically who developed the MTO’s and the methodology used.

Planning Basis This section documents the project management, engineering, design, procurement, fabrication, and construction approaches to the project. The contracting and resource strategies should be identified, as well as any assumptions that were made with regard to the workweek schedule (hours worked per day, days worked per week, shifts worked per day, etc.) and planned use of overtime. Any assumptions made regarding constructability, modularization, use of specialized construction equipment should also be noted here.

The overall project schedule and key milestones should be identified.

Basis of Estimate 3 of 6

May 2, 2007 Cost Basis Describe the methods and sources used for determining all material, labor and subcontract pricing. Identify the following:

• Pricing sources for all major equipment (vendor quotes, historical data, etc,). • Bulk material and commodity pricing sources, including any discount strategies. • The pricing source for all labor hours, and all labor productivity adjustments. Provide appropriate detail if productivities vary by trade and/or location within the project (plant, etc.). • All wage rates used (including crew/craft rates, craft mix, etc.). Identify all items included in all-in rates (if used). • Pricing source and methodology for construction indirects. • Pricing source for all start-up costs. • Pricing source and methodology for all home office costs (project management, engineering, design, etc.). Document the basis for any contractor fee costs. • Pricing source and methodology for costs such as freight, taxes, duties, etc. • Pricing source for any owner’s costs included in the estimate. • Currency exchange rates if applicable, as well as the stability and/or volatility of rates. • Escalation indices used, and the method of calculation (including duration). • Contingency development and basis. • Location factors used and the basis for these factors. • Influence of local market conditions. • Capital costs vs. expense costs, or other categorization as necessary. • Any other pricing factors or external influences that may have a significant impact on project cost should be identified. Allowances In this section, identify the level and types of allowances used in the estimate. Describe the basis for the common estimating allowances such as material take-off allowances, overbuy allowances, design allowances for engineered equipment, congestion allowances, working height allowances, etc.

This section should also describe any other costs that have not been detailed in the body of the estimate, such as lump-sum allowances for specific areas of scope or any other factored costs not described elsewhere in the estimate basis.

Assumptions Any other assumptions made by the estimator but not documented elsewhere in the estimate basis should be included in this section. This may include such assumptions as an adequate labor supply being available, adequate funding available, site conditions, etc. Small assumptions can change into major assumptions throughout the life of the project. Therefore, it is better to document assumptions then not to document at all.

Exclusions In this section, the estimator should document all potential items of cost which a reviewer might associate with the project, but for which no costs have been included in the estimate. Asbestos abatement, removal of hazardous wastes, acquisition of land, taxes, financing costs, licensing costs, etc. are examples of potential items that may need to be identified.

Exceptions The estimator should identify any anomalies or variances to your organization’s standard estimating practices. This section should document any significant deviations from the project and/or engineering deliverables normally required for the applicable class of estimate. A good practice is to provide a checklist as an attachment to the BOE that will document any exceptions that are identified. This checklist should correspond to the company’s standard estimating practices.

May 2, 2007 Risks and Opportunities Any areas of the estimate containing significant risk or opportunity should be identified. If a formal risk analysis study has been prepared then it should be described (e.g. methodology, technique, etc.). In particular, this section should identify those cost elements that have been identified with high or very high risk or opportunity values. The risk analysis report (or summary) should be provided as an attachment to the BOE.

Contingencies Contingency is a cost element of the estimate used to cover the uncertainty and variability associated with a cost estimate, and unforeseeable elements of cost within the defined project scope. Contingency covers inadequacies in complete project scope definition, estimating methods, and estimating data. Contingency specifically excludes changes in project scope, and unforeseen major events such as earthquakes, prolonged labor strikes, etc. The amount of contingency included in the estimate should be identified, as well as the methods used to determine the contingency amount. If risk analysis techniques were utilized to develop the contingency amount, the associated confidence level should also be identified.

Management Reserve Contingency is not intended to cover the costs associated with changes in project scope. If the project needs to provide an allowance for anticipated changes in scope, or to cover the costs for items that may be required but have not yet been specifically identified as being included in the current project scope, then that amount of cost, typically referred to as management reserve, should be identified here.

The intended purpose and use of management reserve should be clearly identified. The approval process, management and tracking of the management reserve should also be clearly identified.

Reconciliation Provide an overview of the major differences between the current estimate and the last published estimate prepared for this project. Identify the cost impacts due to scope changes, pricing updates, labor productivity adjustments, estimate refinement, etc. A more detailed reconciliation or cost trending report can be provided as an additional attachment if necessary.

Benchmarking This section should document any comparisons of overall estimate metrics, ratios, and factors with similar projects, historical data, and industry data. Projects used in the benchmark comparisons should be similar in process type and overall value. If significant variations of the estimated project costs versus the benchmarks exist, those inconsistencies should be identified and commented upon. A more detailed benchmark analysis report may be included as an attachment to the BOE.

Estimate Quality Assurance Since estimate reviews are the means for testing the quality of the estimate, this section of the BOE should identify all estimate reviews that have taken place to date, and any additional reviews that are proposed to take place. All review comments or analysis should be included as an attachment to the BOE.

Estimating Team In this final section, all members of the estimating team should be identified, including roles and responsibilities.

Attachments Several supporting documents will generally be included with the basis of estimate. 1) Attachment A: Estimate Deliverables Checklist Attachment A: Estimate Deliverables Checklist

Identify the revisions and date of issue for key documents.

Additional Attachments Include any other attachments that may be necessary or required (reconciliation report, benchmarking report, risk analysis report, escalation calculations, etc.).

LEVEL OF DEATIL IN THE BASIS OF ESTIMATE

It is often not a simple matter to determine just how much detail should be provided in a BOE. Several factors may come into play during the preparation of the cost estimate that will help determine that answer but, it is the estimator’s best judgment that will ultimately decide the appropriate level of detail in the BOE.

Level of Project Definition Estimates are prepared at various stages of a project. A more detailed estimate will generally require a more detailed BOE, however that is not always the case. A conceptual estimate will probably be based on a limited amount of scope but may require a more detailed basis of estimate. It's not uncommon for a BOE for a conceptual estimate to be more thorough than one prepared for a more detailed estimate because there are often more assumptions made at the conceptual stage of a project that require greater documentation.

Conversely, there may be times when the project definition is so complete or simplistic that a BOE does not require a great amount of detail. A three or four page document may be sufficient to convey the BOE.

Cost Value of the Project Typically, a more expensive a project will require a more detailed BOE. However, projects of lesser cost can require an extensive BOE to fully communicate major assumptions that constrain or reduce the cost.

Type of Project The type of project can also affect the BOE. For example, the BOE for a direct purchase (e.g., single piece of large equipment) may be less detailed than for a construction project

Other Factors Other factors that affect the level of detail in a BOE are: work breakdown structure (WBS), consideration for new technologies, contracting strategy, etc.

The BOE should contain a concise level of detail to fully support the review of the estimate by those that have not been a part of the preparation of the estimate. The BOE provides a definition of the scope of the project as estimated, and should establish the basis for change management subsequent to publication of the estimate.

Chapter 5 – Contingency

Introduction

The cost of constructing large capital projects can be subject to significant risks and variability that if not properly managed and addressed, can result in significant estimating errors. This risk must be managed through the proper use of allowances, contingencies, and management reserve to help minimize variations in cost estimates as the project advances through the different stages of development. While applying contingency to cost estimates cannot guarantee that a budget established at some milestone during project development will not be exceeded when the project is bid, properly applied contingency can decrease this probability.

Allocation of contingency at every phase of cost estimating should be based on sound cost estimating practices and must be allocated based on established risk factors. The amount of contingency needed and the risk factors that this contingency addresses shifts throughout project development and the estimate must reflect these shifts. For example, in the early stages of estimating, project definition level is the most important factor in cost estimating risk and a significant amount of contingency must be applied to offset this risk. In later stages of project development, project definition is often well-established and other risk factors such as market conditions or material escalation rise in importance. Fixed contingency allocations at various stages of project development often lead to substantial estimating error and do not necessarily reflect the measurable project risks.

Industry best practice dictates that all cost estimates, regardless of the phase in the project development cycle, carry some level of funding for unknown project conditions. This funding is typically termed contingency, and may affect the ultimate cost of the project. When evaluating contingency, impacts of delays to the project schedule must also be considered as they may significantly affect the final cost of a project.

Levels of contingency may vary as project development progresses, and the methods for determining contingency amounts may differ Figure 5-1 E x a m p l e o f E s t i m a t e from project to project, but a Distribution at E a c h E s t i m a t e C l a s s structured approach for de- in the Project Life Cycle termining contingency must What is Shown be followed and documented What is Know but Not Shown during estimate preparation. 250 Contingency As the design progresses, the 200 required contingency should 150 normally decrease reflecting 100 the increased certainty in the 50 project scope and the oppor- ENGINEER’S ESTIMATE ($M) ENGINEER’S ESTIMATE 0 tunity to mitigate risks. 5 4 3 2 1 ESTIMATE CLASS

Adding contingency to cost estimates does not guarantee that the budget established during the estimating process will not be exceeded by bid prices. Contingency amounts are inversely proportional to the probability of a budget being exceeded (i.e. the more contingency included, the lower the chance of exceeding the budget). Through statistical analysis of bidding history coupled with specific information about the project at hand and current market conditions; a probability curve of the expected bid price can be developed (See Figure 5-2). It becomes a management function to decide on an acceptable probability of a budget overrun and thus the level of contingency to be included in the budget.

Contingency Definitions

Many industries, agencies, and companies define the amount carried for project unknowns differently. Common terms include contingency, allowances, and reserves. To avoid confusion over the terminology used to define these elements in the estimate, the following standard industry terms and their definitions (AACE International Recommended Practice 10S-90, June 2007) and shall be used in all estimate-related documents and correspondence.

Allowances: “Resources included in estimates to cover the cost of known but undefined requirements for an individual activity, work item, account or sub account.”

Contingency: “An amount added to an estimate to allow for items, conditions, or events for which the state, occurrence, and/or effect is uncertain and that experience shows will likely result, in aggregate, in additional costs. Typically estimated using statistical analysis or judgment based on past asset or project experience. Contingency usually excludes:

5-2 Chapter 5 Contingency

1) Major scope changes such as changes in end product specification, capacities, building sizes, and locations of the asset or project; 2) Extraordinary events such as major strikes and natural disasters; 3) Management reserves; and 4) Escalation and currency effects.

Some of the items, conditions, or events for which the state, occurrence and/or effect is uncertain include, but are not limited to, planning and estimating errors and omissions, minor price fluctuations (other than general escalation), design developments and changes within the scope, and variations in market and environment conditions. Contingency must be included in all estimates and the expectation is that this contingency will be expended.”

Management Reserve: “An amount added to an estimate to allow for discretionary management purposes outside of the defined scope of the project, as otherwise estimated. Use of Management Reserve requires a change to the project scope and the cost baseline, while the use of contingency funds is within the project’s approved budget and schedule baseline.” The responsibility for assigning management reserves resides with the BEDC Management and therefore is not covered in this Manual.

Key Sources of Risk and Variability

There are five key factors that contribute most significantly to variability in cost estimating. These five factors include: 1. Project Definition Level 2. Estimating Methodology 3. Project-Related Risks 4. Escalation of Construction Cost Inputs 5. Construction Market Conditions

It should be noted that “scope creep” (the addition of scope items to a project) can be a significant con- tributor to escalating cost estimates through the project phases but this factor is not included in the list. Management of scope creep is the responsibility of the project management team and the allocation of funds to address scope creep is through a management reserve. The amount of management reserve needed must be assigned by the project management team and dictated to the estimating team. The cost estimator has no information to assess this source of variability and therefore can not be held accountable for the cost implications of unforeseen scope additions.

Each of these five main sources of estimating risk and variability have different levels of emphasis at different phases of a project and thus the amount of contingency allocation to each of the items will shift as the estimate is advanced. While the relevance of each major source of risk will vary due to the nature a given project, the matrix below summarizes the general visibility of each of these factors aligned to each of the five AACE estimating classes.

+ highly visible risk o moderately visible risk - less visible risk

The influence of the various key risk factors is largely based on the ability to predict and quantify each risk at the various stages of project development. For example, in the early stages of a project when construction may be years out, project definition risk may be high and construction market conditions risk may be relatively unknown or unpredictable. As the project progresses, scope definition risk declines while the potential impacts of market conditions become more visible.

Further details on the nature of each of these sources risk and variability are discussed below. Methods for setting contingency are defined in the section following the risk source discussion. Project Definition Level and Estimating Methodology Industry research consistently recognizes project definition as the key factor in the ability to accurately forecast construction costs, particularly in the early phases of project development. Accordingly, the project team must collectively ensure that the project definition level is appropriate for the size, complexity and importance of the project, as well as phase of project development.

Project definition and estimating methodology are intrinsically linked since the level of project definition dictates the appropriate estimating methodology, and therefore, these two factors should be evaluated together when assigning contingency to the estimate. Both project definition and estimating methodology are controlled by the collective project team. By utilizing consistent, structured procedures, the variability of these two controlling elements can be minimized. Project-Specific Risks Project-specific risks refer to conditions or situations specific to a particular project that lack proper definition at any given time during the project development. Project-related risks are present during all stages of project of development, but become better defined and more significant in the later stages of the project.

5-4 Chapter 5 Contingency

Examples of project specific risks include: • Possibility that the selected site may not be available, which could potentially increase the costs for property acquisition, site development costs, conveyance facilities, permit costs, and the associated schedule delays. • Unusual and/or unknown site soil conditions • Other unusual site conditions that could increase costs; proximity to existing facilities, restricted site access, potential environmental mitigation requirements, etc. • Unknown process risks; the possibility that the results a required pilot study may significantly affect the process design, require additional systems, etc. • Permitting risks associated with complicated or lengthy permit processes • Scope risks from public involvement processes that may require implementation of undetermined mitigation measures

Project-related risks should be identified in the risk register on a line item basis and have a contingency amount assigned for each potential risk. In the risk register, the project team should estimate the full cost of the risk (what is the full cost the project would experience) if the risk event did occur, and an associated occurrence probability expressed as a percentage. Risks that have a relatively high probability of occurring should typically be included in the base estimate and not added as a risk factor. Such risks can be listed in the risk register and noted as potential savings, but the cost should be included the base estimate.

The following risks should always be considered and calculated in order to determine the estimate variability. • Material Quantities; the risk that the material quantities have been underestimated due to poor scope definition and/or the method used to determine the quantities. • Material Price; risk associated with material unit prices used in the estimate are inaccurate. • Labor Productivity; risk that labor productivity anticipated by the bidders is less than that included used in the estimate. • Labor Price; risk that labor rates used in the estimate are lower than what will be anticipated by the bidders.

NOTE: Risk for labor and material prices is NOT to account for anticipated escalation. Anticipated escalation should be calculated and included in the base estimate (see Chapter 3). Labor/material price risk is calculated to account for the possibility that the base rates in the estimate are inadequate and abnormal escalation caused by market factors (shortages, etc.).

Amounts to be used as the cost basis for calculating material and labor risk can be extracted from the estimate using the estimate line item codes defined in Chapter 3. Suggested percentages to be used in the analysis are shown in Attachment 5-1. In these tables the (+) percentages should be used to determine risk amounts to be added to the estimate. The (+) and ( – ) percentages should only be used for Monte- Carlo type simulations where range estimating is employed.

When using the above risk factors, the following points must be considered:

5-5 Estimate Review and Approval June 2008

1) Material and labor factors will compound as additional material quantities will require additional installation labor. 2) Factors must be applied before contractor markups (overhead, insurance, profit, etc.). 3) If using these factors for range estimating or Monte-Carlo type analyses, both plus and minus factors should be used. Escalation Risk for Construction Inputs As noted in Chapter 3, “anticipated escalation” is to be included in the base cost of the estimate. “Escalation risk” is the risk that the anticipated escalation included in the base bid will be exceeded due to unforeseen market conditions for a particular resource. For example, if steel prices are projected to increase 4 % per year over the length of the project, this amount of escalation should be included in the base bid. Escalation risk is the risk that steel prices will escalate beyond the 4% per year included in the base estimate.

It is also important to distinguish between “escalation of construction inputs” and “construction market conditions”. Construction inputs include the labor, materials, process equipment, supplies, fuel, etc., that are required to complete the project. Construction market conditions (see below) are reflective of the volume of work available to contractors and affect the overall bid price in addition to the pricing of construction inputs. Construction Market Conditions At later stages in the project development, the construction market is the principal factor leading to variations between cost estimates and bid prices. The “construction service” performed by the general contactor and subcontractors must be viewed as a commodity in itself and analyzed for market conditions that may affect the overall bid price for the project. Current construction market activity and future trends of total construction volume in the local and national market need to be monitored and taken into account when forecasting bid prices. For the local market, DEP can network with other large public agencies in the area (Ports Authority, DDC, etc.), labor unions, trade associations (AGC of New York, General Contractors Association), etc. to gauge the level of upcoming construction activity. In addition, commercially-available local and national forecasts can be used which include McGraw-Hill Construction Research and Analytics and Global Insight.

A variety of factors may lead to market conditions that result in above-normal bid prices. These factors include: • Number of bidders • Bidders perception of risk associated with the project • Length of time between bid and anticipated Notice to Proceed (increases escalation risk to bidders) • Ability to obtain performance bonds • Level of construction activity in the national and local market

Due to the variability and significant impact construction market conditions may have on bid prices, base cost estimates should be priced with standard (typical) contractor markups for risk, profit, and overhead.

5-6 Chapter 5 Contingency

Any adjustments to the standard markup should be carried as a separate item in the estimate for visibility and should be referenced to and explained in the Basis of Estimate document. The estimating team should recommend an adjustment based on their experience with the local market, but BEDC Management should make the final determination on the amount of any adjustment to the standard markups. A detailed discussion of various methods for monitoring market conditions is included at the end of this chapter.

As standard markups for subcontractor profit/overhead, contractor overhead/profit, insurance/bonds, and normal escalation may vary according to economic and market conditions, they should be obtained from the BEDC Cost Estimating Division prior to finalizing an estimate. See estimate procedures and formats in Chapters 3 and 4 for instructions on calculating and summarizing adjustments to the standard markups.

Other than research on the number of bidders vs. bid prices (discussed below), little published research ex- ists that can be used to predict variances in bid results due to “construction market” conditions, particularly at the local level. The estimating team and other members of the project team must analyze both the global and local market conditions to determine recommended general contractor and subcontractor markup percentages to be used in cost estimates. Analysis methods that can be employed by the estimating team include: • “Feels like” surveys of other owners and entities receiving bid prices • Re-pricing historical bids from different time frames • Statistical analysis of bid results

“Feels like” Surveys “Feels like” surveys are non-technical and simply involve gathering the opinion of a number of owners, contractors, estimating professionals, and others involved in receiving bid prices, to formulate an intuitive sense “gut feel” for how bid prices compare to “normal” market conditions. While this is a relatively inexpensive method, it is obviously highly subjective.

Re-pricing of Historical Data Use of this method involves several distinct steps as listed below: 1) Identify two similar projects, one that is a historical project bid prior to the onset of the current market conditions. 2) Extract fully-burdened unit prices (unit prices with all contractor markups included) from an historical internal estimate that used “typical” markups and that has been reconciled to the actual received bid. 3) Adjust these extracted, fully burdened unit prices for the known escalation of construction inputs (labor, materials, etc.). 4) Use these adjusted prices to estimate a recently bid project similar in nature to the historical project. 5) By comparing the estimate of the recently bid project (using the adjusted prices from the historical project), to the actual bid of the recent project gives a qualitative indication of the change in the construction market.

Obviously this method requires identification of projects with enough similarity that the comparison is valid. It is important to note that this process of evaluating construction market conditions is very labor intensive.

5-7 Estimate Review and Approval June 2008

Bid Prices vs. Number of Bidders One of the factors to consider when establishing adjustments to estimated contractor markups is the number of anticipated bidders. Numerous studies have documented the tendency for an increase in bid prices as the number of bidder’s decreases. Many factors affect the number of bidders that will ultimately propose on a given project. Among these, project size, potential risk, and complexity of the project are typically the most influential.

Comparison of the data from the various studies suggests that although the effect of the number of bidders on bid prices is “universal”, the data sets do not support a single mathematical model. Variance between the studies is likely due to factors associated with the construction type, location, and other owner-specific variables. Even with the variance between the studies, they can be used to formulate suggested guidelines on the potential effect on bid prices of a lower than normal number of bidders. When evaluating construction market conditions, the following guidelines should be considered when less than four bidders are anticipated: 3 bidders – up to 15% of the total estimated bid price 2 bidders – 20 to 30% of the total estimated bid price 1 bidder – 25 to 40% of the total estimated bid price

The above percentages should be considered approximate guidelines only, as results from individual projects may vary significantly above or below these ranges.

Methods for Setting Contingency

There are a variety of methods for establishing contingency for construction projects. Most methods can be grouped into three main categories as shown in the table below: Table 5-2 S u m m a r y o f T y p i c a l C o n t i n g e n c y Estimating Methodologies Ca t e g o r y Me t h o d Pre-Determined Percentages Qualitative Expert Opinion Standard Risk Model Risk Analysis Simplified Monte Carlo Risk Model Integrated Cost/Model Risk Model

Which method, or combination of methods, used will depend on the available historical data and the nature of the project, (size, complexity, significance). This decision must be agreed upon by the project team and documented in the Basis of Estimate Report. Each method for setting contingency is described later in this chapter.

5-8 Chapter 5 Contingency

The table below summarizes the minimum requirements for contingency setting methods to be for all estimates prepared for BEDC based on the estimated project value and estimate class. Methods are described in detail in the following section.

Notes: 1) Regardless of the method(s) used to analyze contingency, pre-determined percentages shall also be established by the estimating team. The amount of contingency included in the estimate shall not be less than that calculated by the pre-determined percentages appropriate for the class of estimate unless approved by the BEDC project manager. 2) Where a formal risk analysis is performed, the risk register shall also be prepared and used as input for a portion of the risk analysis.

Pre-Determined Percentages One commonly used practice is to add contingency to the base Es t i m a t e AACE Rec o m m e n d e d cost estimate using pre-determined percentages such as those Cl a s s Co n t i n g e n c y recommended in AACE Recommended Practice 18R-97. Us- L: -20% to -50% 5 ing pre-determined percentages is the minimum requirement for H: +30% to +100% L: -15% to -30% determining contingency amounts. Pre-determined percentages 4 H: +20% to +50% may need to be supplemented with other methods depending on L: -10% to -20% 3 the nature of the job. H: +10% to +30% L: -5% to -15% Recommend percentages in AACE 18R-97 were determined from 2 H: +5% to +20% industry research, including regression analysis of historical proj- L: -3% to -10% 1 ect data. However, since they represent average results, simply H: +3% to +15% applying them to base cost estimates without further analysis may not provide an adequate picture of project risk. The expected accuracy ranges listed in AACE 18R-97 are defined as the “… typical variation in low and high range after the application of contingency (determined at a 50% level of confidence). Typically, this results in a 90% confidence that the actual cost will fall within the bound of the low and high ranges.”

5-9 Estimate Review and Approval June 2008

The AACE recommended contingency percentages are a range for each estimate class. Determination of the value included in the estimate should be done by evaluating a number of factors, including: • Level of project definition; poorly-defined projects require higher contingency • Complexity of the project; more complex projects require higher contingency • State of the technology involved with the project; new technology represents higher risk • Experience of the estimating team with the particular type of project • Time allowed to prepare the estimate • Quality of the cost data available • Overall quality of the estimate

In addition to the project team evaluating the above factors and recommending a contingency percentage to be included in the estimate, the significance of the project in terms of impact to the overall DEP capital program. Projects that cannot be delayed due to consent decrees or other obligations or considerations, should carry a higher contingency (closer to the high end of the recommended range), even if the other factors would justify a contingency at the lower end of the range. Expert Opinion Contingency may be set based on the experience of the estimators and other members of the project team. This method takes the nature of the project and specific risk factors into account, and therefore may provide a more realistic projection than pre-determined percentages. However, it is very subjective and heavily reliant on the availability of experts with a background relevant to the particular project. The level of detail and structure when using the expert opinion approach can vary widely, from assigning an overall project contingency, to assigning a contingent amount to discrete WBS elements and additional risk drivers. This method should only be used when experts with specific, relevant experience with all aspects of the project are available, and only with specific approval from the BEDC project manager. Risk Analysis Risk analysis can be used to evaluate appropriate levels of contingency for a project. In addition, risk analysis sessions add value to the project development process since they require the project team to identify risks and analyze options to mitigate these risks to reduce the overall project impact. In addition to generating a recommended value for contingency, risk analysis sessions provide feedback on: 1) Areas of the design that might require additional development 2) Risk mitigation strategies 3) Identified risk items that may require involvement by management

Risk analysis methods vary in complexity and effort required to employ them. Common methods include: • Standard Risk Model • Simplified Monte Carlo Risk Model • Integrated Cost/Schedule Risk Analysis

Standard Risk Model One of the simplest risk analysis methods, sometimes referred to as the “standard risk model”, consists of the following steps: 1) Assemble a risk register by identifying and listing each risk elements associated with project completion. 2) Assign an estimated cost and schedule impact to each risk element (cost to the project should the risk element occur). 3) Assign a probability (percent chance) that the risk element will occur. 4) Calculate the expected net risk by multiplying the cost and schedule impact of each risk element times the associated probability. 5) Sum the expected net risk of each risk element to calculate the total risk for the project.

This method is also known as Expected Value and Expected Net Risk. One disadvantage of this method is that it produces a “single point” contingency that does not provide a probability of the calculated contingency being exceeded. Use of the risk register to support risk identification and management is detailed in the BEDC Project Delivery Manual and a copy of the latest standard risk register template should be obtained from your BEDC PM at the initiation of every project.

Simplified Monte Carlo Risk Model The standard risk model can be enhanced to generate probabilities on whether a given contingency amount will be exceeded. For each line item in the risk register, minimum, most likely, and maximum values of budget and schedule impact are determined to create a triangular distribution for each line item. Using the triangular distributions and associated probability of occurrence for each line item as input, a simple Excel- based Monte Carlo simulation generates an estimated project cost (base estimate cost plus contingency) for a range of probability values (50%, 60%, 70% 80%, 90%, etc.). The results can be presented as a probability distribution curve or in a table format.

As an example of this method, the base estimate for a project may be $100M. By adding a contingency of $30M, the probability of not exceeding the total projected cost of $130M might be increased to 80%. By adding contingency of $50M (total projected cost of $150M) the chance of not exceeding the total projected amount might be increased to 90%.

In general, the required input consists of: • Base estimate amount (cost and schedule) • Estimate certainty (base estimated cost and schedule) • Assignment of a probability that the risk will happen. • Assignment of individual line items in the risk log with separate minimum amounts, most likely amounts, and maximum amounts. • Schedule impact in months (minimum, maximum, most likely)

Detailed instructions for using the Simplified Monte Carlo Risk Model, along with a template and sample, should be obtained from your BEDC Project Manager at the initiation of a project.

Integrated Cost/Schedule Risk Model The Integrated Cost/Schedule Risk Model uses Monte Carlo simulation techniques to generate the most likely outcome of the combination of all the risk items (both cost and schedule) associated with a project. Commercial off-the-shelf software is available to perform Monte Carlo simulations. A complete Monte Carlo simulation requires extensive involvement from the project team and should be facilitated by an individual experienced with the process.

One common approach is to use Monte Carlo simulation in conjunction with range estimating. Under this approach, line items at a certain WBS level in the estimate are assigned ranges as opposed to a single cost amount. This requires the estimator to assign a minimum cost, a most likely cost, and a maximum cost for each line in the WBS. Based on the theory that neither the “best case” nor the “worst case” will happen for all line items, the simulation runs multiple iterations of possible cost combinations and possible final values for each line item, and calculates a probability distribution. From this probability distribution, the project team can select a required contingency amount based on the desired confidence level. The desired confidence level translates into the probability that the contingency amount will not be exceeded.

Recent studies have indicated that Monte Carlo-type simulations are not effective in calculating realistic probability distributions on poorly-defined jobs. Without realistic probability distributions, selecting a reasonable contingency becomes impossible. These studies point to several factors that lead to poor simulation results: • Failure to recognize the dependencies between risk items and account for this in the simulation.. • At the early stages of project development, project-specific risk drivers are not readily definable. • Lack of project definition (especially at the early stages of project development) typically leads to over optimistic estimates of project cost and risk. Because of the shortfalls of simulation techniques, they should be used only under the following conditions: • Project definition has progressed to the point where risks are readily definable, and valid range estimates can be performed. • Personnel experienced in Monte Carlo methods are available to facilitate a risk session. • Project size and significance justify the effort required to complete the evaluation.

Chapter 6 Estimate Review and Approval

Chapter 6 – Estimate Review and Approval

Introduction

Three levels of review are required for each cost estimate prepared for BEDC Capital Projects prior to submittal to the BEDC Project Manager. These three levels include:

• Cost estimating team review • Project management and design team review • Consultant senior management review and endorsement

The scope and purpose of these reviews is described in this section.

All reviews shall be performed using the Basis of Estimate (BOE) Report as the reference document and the primary basis for the agenda (see Chapter 5 for details on the BOE Report). In addition to the BOE Report, a complete copy of the project definition package (drawings, specifications, gap analysis, and other related information) should be made available for each review team and shall be available during every review session.

The meeting minutes and notes addressing the disposition of items identified shall be included in the Estimating Quality Assurance section of the BOE document.

The remainder of this chapter describes the quality reviews of the cost estimate

Cost Estimating Team Review Purpose An independent lead estimator that was not involved in preparing the estimate should perform a peer review of the estimate. This review should be performed before the estimate is submitted to the project management and design team.

Areas of Focus The estimate should include a detailed scope review and a detailed pricing review using the following reports:

• Scope Review Report organized by Assembly • Scope Review Report with Line Item Detail • Labor/Productivity Detail Report (Assembly) • Labor/Productivity Detail Report (Item) Labor and Equipment Resource Reports See Chapter 4 – Estimate Outputs for descriptions and samples of these reports.

Outputs The Management Team prepares a cover letter for transmittal of the estimate to BEDC. The cover letter must include the following language:

“We have reviewed the attached project cost estimate. We believe that the estimate conforms to the accepted standard of care for professional practice, that it is complete in terms of scope, schedule, cost of materials, and labor. It is based on current market conditions and an anticipate level of competition and reasonably expected future trends, assuming no outside adverse project impacts or delays. This cost estimate has been escalated on a straight line extrapolation to the midpoint of construction based on the projected start year of construction. The goal was to develop an estimate that would be the second lowest bid if submitted by a contractor in a competitive bid.”

The letter must be signed by the Project Director for all estimates under $200 million in construction value and by the president of the firm (or of each joint venture) for all estimates over $200 million in construction value.
