Transition to Construction Plan 3 Schedule Management This topic covers the following: • Learning Objectives • Why does the PDP include a Schedule Management Plan? • Example of a Schedule Management Plan • What is the PM’s Role in Schedule Management? • How do you create a Schedule Management Plan? • Project Management Tool: The CPM Schedule • Class Exercises & Quiz • Summary 4 Learning Objectives Participants will: • Recognize the value and purpose of a Schedule Management Plan • Be able to complete a Schedule Management Plan • Be familiar with the Preconstruction Schedule Template 5 Why Include a Schedule Management Plan? Accurately estimating and managing project schedules is important to managing CDOT’s construction program. • The schedule indicates whether a project will make the Ad Date. The “Start Construction” and “End Construction” milestones predict when construction funds will be spent. • Managing expenditures helps CDOT to honor commitments to the Transportation Commission, the contracting community, and the public. • Bye-bye SPI ! Hello Ad-date Float! 6 Why Include a Schedule Management Plan? The Project Schedule provides estimated completion dates for project milestones in SAP. These milestones are used to report project progress. The PM enters milestone dates in the SAP Project Portal, populating the Forecast column. SAP milestones are used by the Region to track whether projects will achieve Ad dates. Note: CAPP is the Construction Agreed Price Proposal and it applies to CM/GC contracts. 7 Why Include a Schedule Management Plan? How does it work? The amount of “float” available to the Ad Date is reviewed monthly by the Region and the PMO. Float is the amount of time that an Ad Date can change without impacting the construction schedule. Monitoring float changes from month to month is used to predict expenditures and monitor the Annual Spending Target (set on first working day in January and reviewed monthly). 8 Example Schedule Management Plan 9 What is the PM’s Role in Schedule Management? Develop a Schedule Management Request status from the team Plan. Create the initial Project and update the schedule with Schedule. actual dates. Monitor changes and analyze impacts to the schedule. Use change control when appropriate. 10 How do you create a Schedule Management Plan? The Schedule Management Plan describes the process for developing and managing the project schedule, including: • Roles and responsibilities for updating, and monitoring and controlling the schedule. • The timing of schedule reviews and updates. 11 How do you create a Schedule Management Plan? The Schedule Management Plan consists of: • A narrative or table that describes the development and management of the Schedule and assigns responsibilities for reporting project status • A critical path method (CPM) project schedule that uses a standardized schedule template 12 Project Management Tool: The CPM Schedule A few key scheduling terms: • Activity- A task needed for the accomplishment of a project • Duration- The amount of time needed to complete an activity • Logic – The dependency and sequencing between activities • Float or Slack – The amount of time an activity can be delayed without delaying the project For an introduction to MS Project scheduling, please see the “CPM Scheduling: MS Project 2013 Basic eLearning” course in the LMS. 13 Project Management Tool: The CPM Schedule What is the Preconstruction Schedule Template? A CPM schedule created in MS Project that: • Includes preconstruction activities common to most projects, • Has logic ties and typical durations, and • Needs to be customized with project specific information. 14 Project Management Tool: The CPM Schedule Why can’t I just use a list of milestones or a bar chart? • CPM scheduling calculates the critical path and float or slack. — Recall, float/slack is the amount of time an activity can be delayed without delaying the project. • A CPM analysis provides a basis for discussing realistic dates and schedule risks with your RE. • A CPM schedule can be used to analyze the impact of changes (i.e. adding scope) and help make fact-based decisions. 15 Project Management Tool: The CPM Schedule Can a “one-size” template really fit all projects? • Developed by several Region folks to be representative of a “typical” project • Durations can, and should, be adjusted to be project-specific • Has built-in logic to save development time • Promotes consistency and supports portfolio analyses • Supports future implementation of new PM software tools 16 Project Management Tool: The CPM Schedule The Template: • Can be customized by activating/deactivating activities (we advise against adding/deleting activities) • Is pre-programmed with logic ties • Is organized using key project milestones • Includes the six Milestones needed for SAP 17 Project Management Tool: The CPM Schedule To use the Schedule Template, the PM will: • Need MS Project (contact the Service Desk) • Consult with groups and Specialty Units that have a role in the project • Determine the work required to complete the project: — Determine applicable activities (de-activate unneeded activities; don’t delete them, because you might need them later and/or it could impact schedule logic!) — Estimate activity durations — Tailor the schedule template 18 Project Management Tool: The CPM Schedule How do you estimate durations? • Utilize your past experience • Engage the Team – Team members need to provide durations for their activities (or concur with durations in template) – Note, they are often balancing commitments to multiple projects – Asking team members to help create the schedule helps to get buy-in (specialty units, stakeholders, etc.). – Involved team members are more likely to be committed to meeting the schedule 19 Project Management Tool: The CPM Schedule Other ways to estimate durations: • Get Advice / Phone a Friend — An experienced PM in your Region • Use Analogous Estimates – Research durations used in similar projects • Use Parametric Estimates – Extract quantities and time durations/unit 20 Project Management Tool: The CPM Schedule At FIR, the current schedule becomes the baseline or plan. • Changes after this point may require formal change control • Analyze the critical path and the completion date to determine if your project is on track to be advertised as planned • Use the schedule when changes are contemplated and analyze impacts; use “what if” analyses to help make decisions (hint: when doing “what if” scenarios, use a temporary copy of the file) • Update the schedule when changes have been approved 21 Project Management Tool: The CPM Schedule Update the schedule to reflect: • Actual completion dates – Make sure “auto schedule” is the default • New activities and/or estimated durations due to changes (Recommend using activate/deactivate feature for changes to scope) 22 Demonstration of Template Schedule Demo showing: • How to use Activate/Inactivate • How to Hide/Unhide activities There are two templates available on the website: • A fully expanded version, with all activities active • A “Simple” version with nearly half of the activities de- activated and hidden 23 Baseline Schedule Exercise Open the file Schedule Template -- workshop exercise #1.mpp on your desktop • The oldest person in the group is the “driver” • Verify Ad-date = 11/03/2020 (line #146) • In mid-October 2020, the ROW Manager informs you: — It has become all too clear that CDOT will need to proceed to condemnation from a landowner for ROW needed to flatten a curve — The condemnation will delay the ROW clearance until mid-December-2020 (30 additional working days on line #137 are anticipated) 24 Anticipated Ad-date? What is your new Ad-date? • Correct answer = 12/17/2020 Anyone see anything unusual on the Ad-date line? Any thoughts on what the PM should do? 25 Schedule Maintenance/Upkeep Exercise Open the file Schedule Template -- workshop exercise #2.mpp on your desktop • The youngest person in the group is the “driver” • Verify Ad-date = 11/03/2020 (line #146) • Modify using info below: — In mid-March 2019, the design consultants inform you their FIR plans were so clean that it took only a couple of weeks to finalize the FOR plans — They will be ready to have the FOR Meeting on 04-01-2019 rather than 07-26-2019 — After speculating that witchcraft must have been involved, you decide to do a “what if” scenario by entering an Actual Finish of 04-01-2019 for the FOR Meeting. (line #105) 26 Anticipated Ad-date? What is your new Ad-date? • Correct answer = 07/08/2020 • It was originally 11/03/2020 Assuming the PM is 100% convinced the consultant’s information and assessment is accurate, any thoughts on what the PM might consider doing? 27 When to Create and Maintain Schedule? When should the PM create the schedule? • At/prior to Design Scoping Review Meeting At what point of the project should maintenance of the schedule occur? • Throughout the design phase 28 Summary The Schedule Management Plan provides the framework for creating and managing the project schedule. • Engaging the team to develop the schedule helps create buy-in with schedule commitments. • CPM scheduling provides a valuable tool that can be used to track progress and evaluate impacts from changes. 29 Questions/Discussion 30.

  • Overview of Project Scheduling Following the Definition of Project Activities, the Activities Are Associated with Time to Create a Project Schedule
    Project Management Planning Development of a Project Schedule Initial Release 1.0 Date: January 1997 Overview of Project Scheduling Following the definition of project activities, the activities are associated with time to create a project schedule. The project schedule provides a graphical representation of predicted tasks, milestones, dependencies, resource requirements, task duration, and deadlines. The project’s master schedule interrelates all tasks on a common time scale. The project schedule should be detailed enough to show each WBS task to be performed, the name of the person responsible for completing the task, the start and end date of each task, and the expected duration of the task. Like the development of each of the project plan components, developing a schedule is an iterative process. Milestones may suggest additional tasks, tasks may require additional resources, and task completion may be measured by additional milestones. For large, complex projects, detailed sub-schedules may be required to show an adequate level of detail for each task. During the life of the project, actual progress is frequently compared with the original schedule. This allows for evaluation of development activities. The accuracy of the planning process can also be assessed. Basic efforts associated with developing a project schedule include the following: • Define the type of schedule • Define precise and measurable milestones • Estimate task duration • Define priorities • Define the critical path • Document assumptions • Identify risks • Review results Define the Type of Schedule The type of schedule associated with a project relates to the complexity of the implementation. For large, complex projects with a multitude of interrelated tasks, a PERT chart (or activity network) may be used.

  • Scheduling: Introduction
    7 Scheduling: Introduction By now low-level mechanisms of running processes (e.g., context switch- ing) should be clear; if they are not, go back a chapter or two, and read the description of how that stuff works again. However, we have yet to un- derstand the high-level policies that an OS scheduler employs. We will now do just that, presenting a series of scheduling policies (sometimes called disciplines) that various smart and hard-working people have de- veloped over the years. The origins of scheduling, in fact, predate computer systems; early approaches were taken from the field of operations management and ap- plied to computers. This reality should be no surprise: assembly lines and many other human endeavors also require scheduling, and many of the same concerns exist therein, including a laser-like desire for efficiency. And thus, our problem: THE CRUX: HOW TO DEVELOP SCHEDULING POLICY How should we develop a basic framework for thinking about scheduling policies? What are the key assumptions? What metrics are important? What basic approaches have been used in the earliest of com- puter systems? 7.1 Workload Assumptions Before getting into the range of possible policies, let us first make a number of simplifying assumptions about the processes running in the system, sometimes collectively called the workload. Determining the workload is a critical part of building policies, and the more you know about workload, the more fine-tuned your policy can be. The workload assumptions we make here are mostly unrealistic, but that is alright (for now), because we will relax them as we go, and even- tually develop what we will refer to as ..

  • Scheduling College Classes Using Operations Research Techniques Barry E
    A03 - 2008 Scheduling College Classes Using Operations Research Techniques Barry E. King, Butler University, Indianapolis, IN Terri Friel, Roosevelt University, Chicago, IL ABSTRACT This paper outlines efforts taken at Butler University’s College of Business Administration to construct semester class schedules using a mixed integer linear programming problem to develop a schedule of classes and an assignment procedure to assign faculty to the schedule. It also discusses our experiences with the effort and suggestions for improvement. INTRODUCTION At Butler University, multiple sections of classes are scheduled in an attempt to give students a wide choice of options in constructing their individual class schedule. Many constraints are imposed such as not having senior level classes on Fridays so seniors can better participate in internship activities and not having junior and senior classes in the same discipline offered at the same day and time. There is also desire from administration to spread the classes out during the day to avoid an unusual number of classes being offered during the prime late morning and early afternoon hours thus better using classroom facilities. BACKGROUND The literature is full of course scheduling research. An early work by Shih and Sullivan [4] discusses course scheduling via zero-one programming but the work was hampered by the lack of adequate solvers of the time. Mooney, Rardin, and Parmenter [3] discuss large-scale classroom scheduling at Purdue University. Dinkel, Mote, and Venkataramanan [1] and Fizzano, and Swanson [2] discuss heuristics for classroom and course scheduling. Wang [5] uses a genetic algorithm to solve a course scheduling problem. Our work departs from these previous efforts in that it takes a two-stage optimization approach to the problem faced at Butler University and solves the problem with solvers available through SAS.

  • Critical Path Method (CPM) Scheduling Terminology
    Critical path Method (CPM) Scheduling Terminology Activity: A task or process to be accomplished in a set period of time as part of working toward a larger project goal. An Activity can be assigned to a resource(s) and have an associated cost. Activities are ordered with logic links. Activity Code: An alphanumeric value by which activities can be grouped and filtered. A code is assigned to each activity. Activity Relationship: An ordered link between 2 activities representing the order of execution. There 4 relationship types are: FS – Finish to Start SS – Start to Start FF – Finish to Finish SF – Start to Finish Baseline Schedule: A Baseline Schedule is a fixed CPM schedule that reflects the original scope of work for the project, and the Contractors’ intended sequence for completing the original scope of work that is the standard by which project performance is measured. Constraint: A date restriction imposed on an activity’s start or finish date in scheduling software. Applying a constraint will swap the computed date to a date imposed by the user. Often used to imposed deadlines or to delay activities in a schedule. Contract Completion Date: The date established by the Contract for completion of all work for the project. Critical Activity: An activity that is on the project’s critical path. Critical Path: The critical path is the longest continuous path of activities through the contractual completion milestones in the CPM schedule that establishes the project scheduled completion date. The critical path is typically the path of activities with the least total float. The critical path may follow different paths of activities at different times during the performance of the work due to the progress of the work or revisions made to the schedule.
