Question Set 5 Northern Construction Service, Inc. e-mail dated January 3, 2019

Question 5-1) This contract contains item 183.11 Treatment of Contaminated Groundwater, paid by the lump sum. Treatment of groundwater is typically paid under item 183.1, which is paid per gallon. A lump sum pay item for this work puts all the risk on the contractor because of unknown subsurface conditions. The amount of water that needs to be handled and treated on this particular project could be a very large quantity or could be minimal depending on testing and actual field conditions at the time of construction. If the item remains a lump sum, this risk will need to be built into the project which could result in higher than anticipated pricing. We therefore request that the department change the payment of this item to a per gallon price to reduce the risk to the contractor due to these unknown conditions.

Response 5-1) The amount of water that needs to be handled is highly dependent on the Contractor’s means and methods as well as the Contractor’s proposed schedule and dewatering system design. The amount of groundwater that requires Treatment of Contaminated Groundwater is dependent on the testing performed by the Contractor, the Contractor’s site management, layout of potential onsite recharge pits, and seasonal fluctuation in groundwater levels. Information on groundwater elevations can be found in the geotechnical report dated December 3, 2015 (A00804-3). Determination of contamination levels of groundwater are to be determined by the Contractor. Basic treatment of groundwater for total suspended solids is included in item 991.1. Item 183.11 is intended to capture the cost of mobilization, operation, and maintenance of the contingency treatment system (if required as determined by the Engineer it is necessary to comply with a Remediation General Permit (RGP)).

Question Set 6 Baltazar Construction, Inc. e-mail dated January 4, 2019

Question 6-1) Plan Sheet #10 calls out for the removal of SMH 18B7 & SMH 18B6, removal of existing 42” RCP and two (2) locations to cut & plug RCP. How are these items to be paid?

Question 19-1) On the above referenced project, Under Item # 824.211 there is an item for an Infrared Pedestrian Detection System specified. The equipment required to meet this specification is extremely complicated and so costly it more than doubles the cost of the entire system. The City of Springfield currently has numerous RRFB crosswalk systems which our company had supplied on DOT contracts that are activated by pedestrians using a push button. Mass DOT specifications for RRFB crossings in Springfield typically require pedestrian push buttons for activation (see attached) therefore would it be acceptable to remove the requirement for the Infrared Pedestrian Detection System and replace it with your standard specification?

Response 19-1) The City of Springfield has agreed to the elimination of the Infrared Pedestrian Detection System and instead install the typical push button controls. Updated special provision and plan are attached to this Addendum.

COMMONWEALTH OF MASSACHUSETTS PUBLIC EMPLOYMENT LAWS Revised February 20, 2019

The Contractor's attention is directed to Massachusetts General Laws, Chapter 149, Sections 26 through 27H, and 150A. This contract is considered to fall within the ambit of that law, which provides that in general, the Prevailing Rate or Total Rate must be paid to employees working on projects funded by the Commonwealth of Massachusetts or any political subdivision including Massachusetts Department of Transportation (MassDOT).

A Federal Aid project is also subject to the Federal Minimum Wage Rate law for construction. When comparing a state minimum wage rate, monitored by the Massachusetts Attorney General, versus federal minimum wage rate, monitored by the U.S. Department of Labor Wage and Hour Division, for a particular job classification the higher wage is at all times to be paid to the affected employee.

Every contractor or subcontractor engaged in this contract to which sections twenty-seven and twenty-seven A apply will keep a true and accurate record of all mechanics and apprentices, teamsters, chauffeurs and laborers employed thereon, showing the name, address and occupational classification of each such employee on this contract, and the hours worked by, and the wages paid to, each such employee, and shall furnish to the MassDOT's Resident Engineer, on a weekly basis, a copy of said record, in a form approved by MassDOT and in accordance with M.G.L. c. 149, § 27B, signed by the employer or his/her authorized agent under the penalties of perjury.

Each such contractor or subcontractor shall preserve its payroll records for a period of three years from the date of completion of the contract.

The Prevailing Wage Rate generally includes the following:

Minimum Hourly Wage + Employer Contributions to Benefit Plans = Prevailing Wage Rate or Total Rate

Any employer who does not make contributions to Benefit Plans must pay the total Prevailing Wage Rate directly to the employee.

Any deduction from the Prevailing Wage Rate or Total Rate for contributions to benefit plans can only be for a Health & Welfare, Pension, or Supplementary Unemployment plan meeting the requirements of the Employee Retirement Income Security Act (ERISA) of 1974. The maximum allowable deduction for these benefits from the prevailing wage rate cannot be greater than the amount allowed by Executive Office of Labor (EOL) for the specified benefits. Any additional expense of providing benefits to the employees is to be borne by the employer and cannot be deducted from the Minimum Hourly Wage. If the employer's benefit expense is less than that so provided by EOL the difference will be paid directly to the employee. The rate established must be paid to all employees who perform work on the project.

When an employer makes deductions from the Minimum Hourly Wage for an employee's contribution to social security, state taxes, federal taxes, and/or other contribution programs, allowed by law, the employer shall furnish each employee a suitable pay slip, check stub or envelope notifying the employee of the amount of the deductions.

No contractor or subcontractor contracting for any part of the contract week shall require or permit any laborer or mechanic to be employed on such work in excess of forty hours in any workweek unless such laborer or mechanic receives compensation at a rate not less than one and one-half times his basic rate of pay for all hours worked in excess of forty hours in such workweek, whichever is the greater number of overtime hours.

Apprentice Rates are permitted only when there is an Apprentice Agreement registered with the Massachusetts Division of Apprentice Training in accordance with M.G.L. c. 23, § 11E-11L.

00860 - 1 Massachusetts Department Of Transportation Highway Division Proposal No. 607589-105920 Addendum No. 5, March 1, 2019

The Prevailing Wage Rates issued for each project shall be the rates paid for the entire project. The Prevailing Wage Rates must be posted on the job site at all times and be visible from a public way.

In addition, each such contractor and subcontractor shall furnish to the MassDOT's Resident Engineer, within fifteen days after completion of its portion of the work, a statement, executed by the contractor or subcontractor or by any authorized officer or employee of the contractor or subcontractor who supervises the payment of wages, in the following form:

STATEMENT OF COMPLIANCE

Date: ______

I , ______do hereby state: (Name of signatory party) (Title)

That I pay or supervise the payment of the persons employed by:

______(Contractor or Subcontractor)

on the ______(MassDOT Project Location and Contract Number)

and that all mechanics and apprentices, teamsters, chauffeurs and laborers employed on said project have been paid in accordance with wages determined under the provisions of sections twenty-six and twenty-seven of chapter one hundred and forty-nine of the General Laws.

Signature ______

Title ______

The above-mentioned copies of payroll records and statements of compliance shall be available for inspection by any interested party filing a written request to the MassDOT's Resident Engineer for such inspection and copying.

Massachusetts General Laws c. 149, §27, requires annual updates to prevailing wage schedules for all public construction contracts lasting longer than one year. MassDOT will request the required updates and furnish them to the Contractor. The Contractor is required to pay no less than the wage rates indicated on the annual updated wage schedules.

MassDOT will request the updates no later that two week before the anniversary of the Notice to Proceed date of the contract to allow for adequate processing by the Department of Labor Standards (DLS). The effective date for the new rates will be the anniversary date of the contract (i.e. the notice to proceed date), regardless of the date of issuance on the schedule from DLS.

All bidders are cautioned that the aforementioned laws require that employers pay to covered employees no less than the applicable minimum wages. In addition, the same laws require that the applicable prevailing wages become incorporated as part of this contract. The prevailing minimum wage law establishes serious civil and criminal penalties for violations, including imprisonment and exclusion from future public contracts. Bidders are cautioned to carefully read the relevant sections of the Massachusetts General Laws.

CONTRACTUAL MILESTONES

This Contract contains the following Contractual Milestones that are to be included in the Contractor’s Baseline Contract Progress Schedule submission. The Contractor shall identify the completion of the work pertaining to each Contractual Milestone through the inclusion of a Finish Milestone and hammock activities in the accepted baseline Contract Progress Schedule using the stated description.

MS#01 – Relief Sewer Relocation MS#02 – Precast Box Culvert & Approach Slab Installation MS#03 – Stage 1 Cast In Place Boat Section Construction MS#04 – Backfill Box Culvert and Prepare Rail Subgrade MS#04 – Stage 2 Cast In Place Boat Section Construction MS#05 – Drainage Pump Station & Force Main Construction MS#07 – Plainfield Street Mid-Block Crossing & RRFB Installed

SUBSECTION 8.06 – LIMITATIONS OF OPERATIONS

The Contractor shall review the outage work window and confirm with Pan Am, MassDOT, Amtrak, and Railroad Operations for agreement and approval. Changes to the work window will require approval of all railroad entities. Any cost associated with additional outages or time shall be borne by the Contractor. The Contractor shall comply with the limits of work window and shall clear the tracks and return the site to The Railroad before the specified time. The site and the tracks shall be in the exact condition the contractor received and allow for trains to operate safely. The Engineer shall be the sole judge of the condition of the site and tracks.

In no event shall the total amount of liquidated damages for failure to complete the above specified work within the windows specified exceed $54,100.00 for any one day. The justification for determining this amount of $850/hr as an average hourly liquidated damage is based on the requirements for loss of revenue from Pan Am. Amtrak damages are based on loss of revenue as well, estimated as a per passenger per day cost, which is $5,700 per day, as well as the cost of bussing for the additional time at $28,000 per day.

The following assumptions were assumed:

A00801 - 4 Massachusetts Department Of Transportation Highway Division Proposal No. 607589-105920

VALUE ENGINEERING CHANGE PROPOSAL (Continued)

g. MassDOT’s Designer of Record will remain the Designer-of-Record for the entire Project. Any costs incurred in the use of MassDOT’s Designer-of-Record by MassDOT or Contractor associated with the review of a VECP are to be included in the calculated net savings.

C. Approval of the VECP shall not occur until a Contract Modification, incorporating the VECP, is issued by MassDOT and properly executed by the Contractor. MassDOT may accept or reject part or all of any VECP at any time prior to an executed Contract Modification for the applicable VECP. The decision of MassDOT, concerning acceptance or rejection of any VECP, shall be final and shall not be subject to dispute resolution.

It is expected that several weeks may go by before the final VECP documentation has been executed with a Contract Modification. Therefore, MassDOT intends to make certain that the initial cost estimate information has not changed before entering into a Contract Modification. As the VECP evaluation process is finalized, and prior to the signed Contract Modification for the VECP, the Contractor and MassDOT must re- certify the current status of the originally proposed cost and/or schedule savings.

Until a contract modification is issued and schedule and cost/savings re-certification is complete and accepted by MassDOT, the Contractor shall remain obligated to perform the Work in accordance with the terms and conditions of the original Contract Documents.

Upon completion of the work associated with the VECP, MassDOT may require verification that the VECP savings has been achieved.

D. VECPs will be processed (distributed, reviewed, commented upon, accepted or rejected) expeditiously (pursuant to M.G.L. c. 30, § 39R); however, as this is an elective modification to the contract, MassDOT shall not be liable for any delay or cost in the review and acceptance of the VECP. During the review of the VECP, the Contractor remains obligated to progress the original Contract scope, and schedule, as planned; until a Contract Modification, accepting the Contractor re-certified VECP, has been executed by MassDOT.

The Contractor has the right to withdraw part, or all of any VECP, prior to acceptance by MassDOT. Such withdrawal shall be made in writing to the Engineer. The Contractor shall state the period of time, from the date of the initial VECP submittal, that the VECP shall remain valid and feasible. Revision of this validity and feasibility period shall be allowed only by mutual agreement of the Contractor and the Engineer in writing.

If the Contractor desires to withdraw the proposal prior to the expiration of this period for non-technical reason, MassDOT reserves the right to recover all actual costs that have been incurred to MassDOT.

A00801 - 43 Massachusetts Department Of Transportation Highway Division Proposal No. 607589-105920

 Addendum No. 5, March 1, 2019

VALUE ENGINEERING CHANGE PROPOSAL (Continued)

If the Contractor withdraws the VEC Proposal, MassDOT reserves the right to proceed with the VECP or any portion of the VECP as a normal change and the Contractor waives any right it may have had to share in net savings thereunder.

For purposes of this provision, expiration of the time established by the Contractor for approval shall be considered as withdrawal by the Contractor if MassDOT requests an extension of that time and the Contractor does not provide a written extension.

E. With regard to unknown conditions or sub-surface work, in general, the expectation is that the Contractor and MassDOT will strive to gain enough knowledge about the risks in order to provide a forward-priced Change Proposal. Therefore, any costs to fully evaluate the proposal, such as additional borings and/or test pits, must be considered in the cost evaluation of whether the VECP is worth pursuing. However, if it is impractical to gather conclusive exploratory information, before the VECP is executed, MassDOT may consider provisions in the VECP that clearly identifies the risk sharing (cost and time) related specifically to the unknown/sub-surface conditions. If these VECP provisions are acceptable to MassDOT they are to include supplemental language to provide a determination of the final savings/cost, and time impacts, no later than 45 days after the sub-surface work is completed. All other aspects of the VECP, unrelated to these Provisions, will be binding upon execution of the VECP.

 The RRFBs shall consist of two and three-sided units with rapidly and alternately flashing rectangular yellow indications having LED-array based pulsing light sources, and shall be designed, located, and operated with the detailed requirements specified herein and on the plans. For Item 824.21.1 the RRFB shall be three-sided units (2 indications per side for vehicle traffic in both directions, and 1 indication visible to pedestrians in the crosswalk to give confirmation that the RRFB is operational).

 Each LED-array, for vehicles, shall be a minimum of approximately 5 inches wide by approximately 2 inches high.

 The front of each RRFB unit shall be approximately 22 inches wide by approximately 4 inches high.

 Each RRFB shall be located between the bottom of the S1-1 or W11-2 sign and the top of the supplemental downward diagonal arrow sign (W16-7p) unless otherwise noted on the plans.

Beacon Flashing Requirements:

 When activated, the RRFB indications shall flash in a rapidly alternating “wig-wag” flashing sequence (left light on, then right light on).

 As a specific exception to the 2009 MUTCD Section 4L.01 requirements for the flash rate of beacons, RRFBs shall have a much faster flash rate. Each of the yellow indications of an RRFB shall have 70 to 80 periods of flashing per minute and shall have alternating but approximately equal periods of rapid pulsing light emissions and dark operation.

During each of its 70 to 80 flashing periods per minute, the yellow indication on the left side of the RRFB shall emit two slow pulses of light after which the yellow indications on the right shall emit four rapid pulses of light followed by a long pulse.

 The flash rate of each individual yellow indication, as applied over the full on-off sequence of a flashing period of the indication, shall not be between 5 and 30 flashes per second, to avoid frequencies that might cause seizures.

 The light intensity of the yellow indications shall meet the minimum specifications of Society of Automotive Engineers (SAE) standard J595 (Directional Flashing Optical Warning Devices for Authorized Emergency, Maintenance, and Service Vehicles) dated January 2005.

 Addendum No. 5, March 1, 2019 ITEM 824.211 (Continued)

Beacon Operation:  The RRFBs, normally dark, shall initiate operation passively via an infrared pedestrian detection system each and every time that a pedestrian is detected, and shall cease operation at a predetermined time limit. This time limit shall be initially set as noted on the plans. The following example is provided to clarify this operation:

If the predetermined flash period is set for 20 seconds and a new actuation is received when the RRFBs have already been flashing for 12 seconds, a new 20- second period will immediately commence, thus resulting in a continuous flashing duration of 32 seconds. If the predetermined flash period is set for 20 seconds and a new actuation is received 1 second after the RRFBs have ceased flashing, a new 20-second period will immediately commence, thus resulting in a flashing duration of 41 seconds with a 1-second interruption.

 All RRFBs associated with a given crosswalk shall, when activated, simultaneously commence operation of their alternating rapid flashing indications and shall cease operation simultaneously.

  The RRFBs shall be activated by ADA compliant pedestrian pushbutton as shown on the plans. The amount of time that the RRFBs remain activated shall be user programmable from 0 to 60 seconds.

 Pedestrian Push Buttons

 The push button shall be and ADA compliant pedestrian push button assembly and require no more than 2 lbs of pressure for activation. The button must be designed so that ice cannot form such that it would impede the function of the button.

 The pushbutton shall incorporate visual feedback to indicate the button has been pressed and the displays are active. Once the pushbutton is pressed, the LED must stay on for the full duration of the beacons active phase.

 The pushbutton shall have transient surge protection that shall include at a minimum a resistor and TVS diode at the input connection. The pushbutton assembly shall be vandal resistant designed to withstand impact from heavy objects. The button bosy must have raised ridges on all sides to protect the button cap against side impacts. The button shall be designed so that it cannot be made to stay on. In the event the button is pressed for longer than 10 seconds, it shall reset itself and work normally even if it is still being held in.

 The button shall be completely sealed and the electronics shall be encapsulated so that the button can function even after being immersed in water for an extended period of time.

The pushbutton shall be capable of continuous operation over a temperature range of -30 degree F to 165 degree F.

ACTIVITY AND USE LIMITATION OPINION

In accordance with the requirements of 310 CMR 40.1074, the Activity and Use Limitation Opinion has been prepared for a parcel of land owned by Curtis Universal Joint and located at 4 Bimie Avenue in Springfield, Massachusetts. As of the date of this Activity and Use Limitation (AUL), the parcel is located in an industrial area and is occupied by a manufacturing facility.

Site History

The Site currently operates as Curtis Universal Joint Company Inc. located at 4 Bimie Avenue, Springfield, Massachusetts. The Site has operated as a manufacturing plant since it was constructed in approximately 1900. The Site property is approximately 1.03 acres in size and is primarily surfaced with an asphalt parking lot. Two buildings are located on the Site, the manufacturing building in the center of the Site and masonry garage to the east.

On December 14, 2006, a 72-hour reportable condition was encountered during the removal of a #2 fuel oil underground storage tank (UST). Immediate Response Action (IRA) activities were conducted under the supervision of an LSP to remedy the release including excavation of fuel oil contaminated soil for off-site disposal. During the characterization of soils for disposal, lead and chromium were detected in stockpiled soil. Subsequent response actions were conducted to fully characterize the metals at the Site. Metals were determined to be present primarily in shallow soils at concentrations exceeding the Method 1 Standards. Polycyclic aromatic hydrocarbons (PAHs) were detected in shallow soils based on laboratory analytical results at the site following visual observations of coal ash in soil and were present above the Method I Standards.

|Note: The "MCP Method I Cleanup Standards" refer to numerical standardsfor chemical contaminants in soil and groundwater which are published in the MCP. The soil standards are broken into three soil categories: S-1, S-2, and S-3. The S-1 Soil Standards are the most strict, or lowest, numerical values since they were derived to be protective of a residential exposure scenario by considering a receptor's incidental ingestion and dermal exposures to soil while gardening and playing. The S-2 and S-3 numerical standards are less strict and therefore higher, having been developed using passive recreational and construction-related exposure scenarios, respectively.I

Reason for Activity and Use Limitation

Due to the presence of contaminants above S-1 standards including Extractable Petroleum Hydrocarbons, PAHs and lead, an AUL is needed to eliminate exposure pathways. The AUL eliminates all exposure pathways except for visitor/trespassers and construction/utility workers. For these exposure pathways that could not be eliminated, a Method 3 Risk Characterization was conducted to evaluate risks posed by contamination remaining in soil at the Site. Based on the Method 3 Risk Characterization, the site poses No Significant Risk for activities and uses consistent with commercial and industrial uses of the site and potential exposures to construction/utility workers, and visitors/trespassers.

[Note: Refer to Exhibit B, a sketch plan showing the relationship of the area subject to the A UL ("Area ofA UL") to the boundaries of the parcel and the disposal site.]

Consistent Activities and Uses

This Opinion provides that a condition of No Significant Risk to health, safety, public welfare or the environment exists for any foreseeable period of time pursuant to 310 CMR 40.0000 so long as any of the following activities and uses occur on the Property:

(i) Activities and uses of the Property including, commercial and/or industrial use, which are not identified by the Notice as being inconsistent with maintaining a condition of No Significant Risk;

Inconsistent Activities and Uses

Activities and uses which are inconsistent with the objectives of this Notice of Activity and Use Limitation, and which, if implemented at the Property, may result in a significant risk of harm to health, safety, public welfare or the environment or in a substantial hazard, are as follows:

(i) Uses that allow children to be present on the property on a high frequency, and/or high intensity basis.

(ii) Relocation of the contaminated soil from the AUL area unless an LSP renders an Opinion which states that such relocation is consistent with maintaining a condition of No Significant Risk.

(iii) Use of the property for residential, daycare, agricultural, playground or non-adult educational use.

Obligations and Conditions

Obligations and/or conditions to be undertaken and/or maintained at the Property to maintain a condition of No Significant Risk shall include the following: i) A Soil Management Plan (the Plan) must be prepared by an LSP and implemented prior to commencement of any activity that is likely to disturb the contaminated soil at the Site. The Plan

A00804-1339.12 Proposal No. 607589-105920 Addendum No. 5, March 1, 2019

must describe appropriate soil excavation, handling, storage, transport and disposal procedures and include a description of the engineering controls and air monitoring procedures necessary to ensure that workers and receptors in the vicinity are not affected by vapors, fugitive dust or particulates. On-Site construction/excavation workers must be informed of the requirements of the Plan and the Plan must be available on Site throughout the course of the project.
