CONTRACTOR/SUBCONTRACTOR CERTIFICATION – CONTRACT COMPLIANCE
(Revision 03-23-10)
Pursuant to 23 C.F.R. § 633.101 et seq., the Federal Highway Administration requires each
Contractor to “insert in each subcontract, except as excluded by law or regulation, the required
Contract provisions contained in Form FHWA–1273 and further requires their inclusion in any
lower tier subcontract that may in turn be made. The required Contract provisions of Form
FHWA–1273 shall not be incorporated by reference in any case. The prime Contractor shall be
responsible for compliance by any Subcontractor or lower tier Subcontractor with the requirements
contained in the provisions of Form FHWA–1273.” The prime Contractor shall therefore comply
with the reporting and certification requirements provided in MassDOT’s
CONTRACTOR/SUBCONTRACTOR CERTIFICATION Form (DOT-DIST-192) certifying
compliance with 23 C.F.R. § 633.101 for each subcontract agreement entered into by the
Contractor. The Contractor shall provide a fully executed original copy of said
CONTRACTOR/SUBCONTRACTOR CERTIFICATION Form to MassDOT upon execution of
any subcontract agreement. Failure to comply with the reporting and certification requirement of
the CONTRACTOR/SUBCONTRACTOR CERTIFICATION Form may result in action against
the prequalification status of the prime Contractor with MassDOT.
SUBSECTION 4.04 CHANGED CONDITIONS.
This Subsection is revised by deleting the two sequential paragraphs near the end that begin “The
Contractor shall be estopped…” and “Any unit item price determined …” (1/6/2006).
PROTECTION OF UNDERGROUND FACILITIES
The Contractor's attention is directed to the necessity of making his own investigation in order to
assure that no damage to existing structures, drainage lines, traffic signal conduits, etcetera, will
occur.
The Contractor shall notify Massachusetts DIG SAFE and procure a Dig Safe Number for each
location prior to disturbing existing ground in any way. Contact the Dig Safe Call Center by
dialing 811 or 1-888-344-7233 or online at www.digsafe.com.

SUBSECTION 8.14 UTILITY COORDINATION, DOCUMENTATION, AND
MONITORING RESPONSIBILITIES
A. GENERAL
In accordance with the provisions of Section 8.00 Prosecution and Progress, utility coordination is
a critical aspect to this Contract. This section defines the responsibility of the Contractor and
MassDOT, with regard to the initial utility relocation plan and changes that occur as the
prosecution of the Work progresses. The Department, with assistance from the Contractor shall
coordinate with Utility companies that are impacted by the Contractor’s operations. To support
this effort, the Contractor shall provide routine and accurate schedule updates, provide notification
of delays, and provide documentation of the steps taken to resolve any conflicts for the temporary
and/or permanent relocations of the impacted utilities. The Contractor shall provide copies to the
Department of the Contractor communication with the Utility companies, including but not limited
to:
Providing advanced notice, for all utility-related meetings initiated by the Contractor.
Providing meeting minutes for all utility-related meetings that the Contractor attends.
Providing all test pit records.
Request for Early Utility work requirements of this section (see below).
Notification letters for any proposed changes to Utility start dates and/or sequencing.
Written notification to the Department of all apparent utility delays within seven (7)
Calendar Days after a recognized delay to actual work in the field – either caused by a
Utility or the Contractor.
Any communication, initiated by the Contractor, associated with additional Right-of-Way
needs in support of utility work.
Submission of completed Utility Completion Forms.
B. PROJECT UTILITY COORDINATION (PUC) FORM
The utility schedule and sequence information provided in the Project Utility Coordination Form
(if applicable) is the best available information at the time of the bid and has been considered in
setting the contract duration. The Contractor shall use all of this information in developing the bid
price and the Baseline Schedule Submission, inclusive of the individual utility durations
sequencing requirements, and any work that has been noted as potentially concurrent utility
installations.
C. INITIATION OF UTILITY WORK
The Department will issue all initial notice-to-proceed dates to each Utility company based on
either the:
1) Contractor’s accepted Baseline Schedule
2) An approved Early Utility Request in the form of an Early Utility sub-net schedule (in
accordance with the requirements of this Subsection)
3) An approved Proposal Schedule
C.1 - BASELINE SCHEDULE – UTILITY BASIS
The Contractor shall provide a Baseline Schedule submission in accordance with the requirements
of Subsection 8.02 and inclusive of all of the information provided in the PUC Form that has been
issued in the Contract documents. This is to include the utility durations, sequencing of work,
allowable concurrent work, and all applicable considerations that have been depicted on the PUC
Form.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 9
SUBSECTION 8.14 (Continued)
C.2 – EARLY UTILITY REQUEST – (aka SUBNET SCHEDULE) PRIOR TO THE BASELINE
All early utility work is defined as any anticipated/required utility relocations that need to occur
prior to the Baseline Schedule acceptance. In all cases of proposed early utility relocation, the
Contractor shall present all known information at the pre-construction conference in the form of a
‘sub-net’ schedule showing when each early utility activity needs to be issued a notice-to-
proceed. The Contractor shall provide advance notification of this intent to request early utility
work in writing at or prior to the Pre-Construction meeting. Prior to officially requesting approval
for early utility work, the Contractor shall also coordinate with MassDOT and all utility companies
(private, state or municipal) which may be impacted by the Contract. If this request is acceptable
to the Utilities and to MassDOT, the Department will issue a notice-to-proceed to the affected
Utilities, based on these accepted dates.
C.3 – PROPOSAL SCHEDULE - CHANGES TO THE PUC FORM
If the Contractor intends to submit a schedule (in accordance with MassDOT Standard
Specifications, Division I, Subsection 8.02) that contains durations or sequencing that vary from
those provided in the Project Utility Coordination (PUC) Form, the Contactor must submit this as
an intended change, in the form of a Proposal Schedule and in accordance with MassDOT Standard
Specifications, Division I, Subsection 8.02. These proposed changes are subject to the approval of
the Department and the impacted utilities, in the form of this Proposal Schedule and a proposed
revision to the PUC form. The Contractor shall not proceed with any changes of this type without
written authorization from the Department, that references the approved Proposal Schedule and
PUC form changes. The submission of the Baseline Schedule should not include any of these
types of proposed utility changes and should not delay the submission of the Baseline
Schedule. As a prerequisite to the Proposal Schedule submission, and in advance of the utility
notification(s) period, the Contractor shall coordinate the proposed utility changes with the
Department and the utility companies, to develop a mutually agreed upon schedule, prior to the
start of construction.
D. UTILITY DELAYS
The Contractor shall notify the Department upon becoming aware that a Utility owner is not
advancing the work in accordance with the approved utility schedule. Such notice shall be
provided to the Department no later than seven (7) calendar days after the occurrence of the event
that the Contractor believes to be a utility delay. After such notice, the Department and the
Contractor shall continue to diligently seek the Utility Owner’s cooperation in performing their
scope of Work.
In order to demonstrate that a critical path delay has been caused by a third-party Utility, the
Contractor must demonstrate, through the requirements of the monthly Progress Schedule
submissions and the supporting contract records associated with Subsection 8.02, 8.10 and 8.14,
that the delays were beyond the control of the Contractor.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 10
SUBSECTION 8.14 (Continued)
All documentation provided in this section is subject to the review and verification of the
Department and, if required, the Utility Owner. In accordance with MassDOT Specifications,
Division I, Subsection 8.10, a Time Extension will be granted for a delay caused by a Utility, only
if the actual duration of the utility work is in excess of that shown on the Project Utility
Coordination Form, and only if;
1) proper Notification of Delay was provided to MassDOT in accordance with the time
requirements that are specified in this Section
2) the utility delay is a critical path impact to the Baseline Schedule (or most recently
approved Progress Schedule)
E. LOCATION OF UTILITIES
The locations of existing utilities are shown on the Contract drawings as an approximation only.
The Contractor shall perform a pre-construction utility survey, including any required test pits, to
determine the location of all known utilities no later than thirty (30) calendar days before
commencing physical site work in the affected area.
F. POST UTILITY SURVEY – NOTIFICATION
Following completion of a utility survey of existing locations, the Contractor will be responsible
to notify the Department of any known conflicts associated with the actual location of utilities
prior to the start of the work. The Department and the Contractor will coordinate with any utility
whose assets are to be affected by the Work of this Contract. A partial list of utility contact
information is provided in the Project Utility Coordination Form.
G. MEETINGS AND COOPERATION WITH UTILITY OWNERS
The Contractor shall notify the Department in advance of any meeting they initiate with a Utility
Owner’s representative to allow MassDOT to participate in the meeting if needed.
Prior to the Pre-Construction Meeting, the Contractor should meet with all Utility Owners who
will be required to perform utility relocations within the first 6 months of the project, to update the
affected utilities of the Project Utility Coordination Form and all other applicable Contract
requirements that impact the Utilities. The Contractor shall copy the Department on any
correspondence between the Utility Owner and the Contractor.
H. FORCE ACCOUNT / UTILITY MONITORING REQUIREMENTS
The Department will be responsible for recording daily Utility work force reports. The start,
suspension, re-start, and completion dates of each of the Utilities, within each phase of the utility
relocation work, will be monitored and agreed to by the Department and the Contractor as the work
progresses.
I. ACCESS AND INSPECTION
The Contractor shall be responsible for allowing Utility owners access to their own utilities to
perform the relocations and/or inspections. The Contractor shall schedule their work accordingly
so as not to delay or prevent each utility from maintaining their relocation schedule.

the Contractor shall obtain the Engineer’s approval prior to modifying to this setting.
K. COST AND RESOURCE LOADING (Types A and B only)
For all Type A and B Schedules, the Contractor shall provide a cost and resource-loaded schedule
with an accurate allocation of the costs and resources necessary to complete the Work. The costs
and resources shall be assigned to all schedule activities in order to enable the Contractor to
efficiently execute the Contract requirements and the Engineer to validate the original plan, monitor
progress, provide cash flow projections and analyze delays.
1. Each schedule activity shall have an assigned cost that accurately represents the value of
the Work. Each schedule activity shall have its resources assigned to it by craft and the
anticipated hours to accomplish the work. Each schedule activity’s equipment resources
shall be assigned to it by equipment type and hours operated. Front-loading or other
unbalancing of the cost distribution will not be permitted.

that is applicable to a specific bid item (cost account.) The total cost for each cost account
must equal the bid item price.
8. For Type A Schedules, each month, the Contractor will be paid using the Cost-loaded
CPM activities for Lump Sum payment items. This requirement supersedes any
requirements elsewhere in this Contract regarding partial payments of schedule-of-
values for all Lump Sum items.
L. NOT TO BE USED IN THE CONTRACTOR’S CPM SCHEDULE
1. Milestones or constraint dates not specified in the Contract
2. Scheduled work not required for the accomplishment of a Contract Milestone
3. Use of activity durations, logic ties and/or sequences deemed unreasonable by the

722.63. Progress Schedule Requirements
A. Baseline Schedule
The Baseline Schedule shall be due thirty (30) Calendar Days after Notice to Proceed (NTP.)
The Baseline Schedule shall only reflect the Work awarded to the Contractor and shall not include
any additional work involving Extra Work Orders or any other type of alleged delay. The Baseline
Schedule shall be prepared and submitted in accordance with Subsections 722.61 - Schedule Content
and Preparation Requirements and 722.62 - Submittal Requirements. Once the Baseline Schedule
has been accepted by the Engineer, with or without comments, it shall represent the as-planned
schedule for the Work and become the Contract Progress Schedule of Record until such time as the
schedule is updated or revised under Subsections 722.63.C - Contract Progress Schedules / Monthly
Updates, 722.64.C - Recovery Schedules and 722.64.D - Proposal Schedules.
The Cost and Resource-Loading information (Types A and B only) shall be provided by the
Contractor within forty-five (45) Calendar Days after NTP.
The Engineer’s review comments on the Baseline Schedule and the Contractor’s responses to
them will be maintained for the duration of the Contract and will be used by the Engineer to monitor
the Contractor’s work progress by comparing it to the Contract Progress Schedule / Monthly Update.
B. Interim Progress-Only Schedule Submissions
The first monthly update of the Contract Progress Schedule/Monthly Update is due within
seventy (70) Calendar Days after Notice to Proceed (NTP.) The Baseline Schedule review period
ends at sixty (60) Calendar Days after NTP, see Subsection 722.60.B - Schedule Reviews by the
Department. If the Baseline Schedule has not been accepted within sixty (60) Calendar Days after
NTP, an Interim Progress-Only Schedule shall be due within seventy (70) Calendar Days after NTP.

Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 23
SECTION 722 (Continued)
C. Contract Progress Schedules / Monthly Updates (Types A, B, C and D)
The first Contract Progress Schedule shall be submitted by the Contractor no later than seventy
(70) Calendar Days after NTP. The data date for this first Progress Schedule shall be sixty (60)
Calendar Days after NTP. Subsequent Progress Schedules shall be submitted monthly.
Each Contract Progress Schedule shall reflect progress up to the data date. Updated progress
shall be limited to as-built sequencing and as-built dates for completed and in-progress activities.
As-built data shall include actual start dates, remaining Work Days and actual finish dates for each
activity, but shall not change any activity descriptions, the Original Durations, or the Original
Resources (as planned at the time of bid), without the acceptance of the Engineer. If any activities
have been completed out-of-sequence, the Contractor shall propose new logic ties for affected in-
progress and future activities that accurately reflect the previously-approved sequencing.
Alternatively, the Contractor may submit to the Engineer for approval an explanation of why an out-
of-sequence activity does not require a correction and an adequate demonstration that the changes
accurately represent how the activities will be built, including considerations for resources,
dependencies and previously approved production rates. Once approved by the Engineer, the
Contractor may incorporate the changes in the next Contract Progress Schedule/Monthly Update
with the affected activities clearly identified and explained in the Schedule Narrative.
No revisions to logic ties; sequence, description or duration of future activities; or planned
resource costs shall be made without prior approval by the Engineer.
Any proposed logic changes for in-progress or future activities shall be submitted to the Engineer
for approval before being incorporated into a Contract Progress Schedule. The logic changes must
be submitted using a Proposal Schedule or a schedule fragnet submission. Once approved by the
Engineer, the Contractor may incorporate the logic in the next Contract Progress Schedule/Monthly
Update with the affected activities clearly identified and explained in the Schedule Narrative.
For any proposed changes to the original sequence, description or duration of future activities,
the Contractor shall submit to the Engineer for approval an explanation of how the proposed
description or duration change reflects how the activity will be progressed, including considerations
for resources and previously approved production rates. Any description or duration change that
does not accurately reflect how the activity will be progressed will not be approved by the Engineer.
Once approved by the Engineer, the Contractor may incorporate the changes in the next Contract
Progress Schedule/Monthly Update with the affected activities clearly identified and explained in
the Schedule Narrative.
Except as otherwise designated by a Contract Modification, no Contract Progress Schedule that
extends performance beyond the Contract Time and/or beyond any Contract Milestone shall be
approved by the Engineer. The Contractor shall submit a Recovery Schedule if any Contract
Progress Schedule/Monthly Update indicates a failure to meet the Contract Dates.
D. Short-Term Construction Schedule
The Contractor shall provide a Short-Term Construction Schedule that details daily work
activities, including any multiple shift work that the Contractor intends to conduct, in a bar chart
format. The daily activities shall directly correspond to the Contract Progress Schedule activities,
with a matching reference to the activity identification number in the Contract Progress Schedule,
and may be at a greater level of detail.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 24
SECTION 722 (Continued)
The Short-Term Construction Schedule shall be submitted every two weeks. It shall display all
work for a thirty-five (35) Calendar Day period consisting of completed work for the two (2) week
period prior and all planned work for the following three (3) week period. The initial submission
shall be provided no later than thirty (30) Calendar Days after NTP or as required by the Engineer.
The Contractor shall be prepared to discuss the Short-Term Construction Schedule, in detail,
with the Engineer in order to coordinate field inspection staff requirements, the schedule of work
affecting abutters and any corresponding work with affected utilities. Short-Term Construction
Schedules shall be prepared and submitted in accordance with Subsections 722.61 - Schedule
Content and Preparation Requirements and 722.62 - Submittal Requirements.
Failure to submit Short-Term Construction Schedules every two (2) weeks may result in
withholding of full or partial payments by the Engineer.
722.64 Impacted Schedule Requirements
A. Notice of Delay
The Contractor shall notify the Engineer in writing, with copies to the District and State
Construction Engineers, within three (3) Calendar Days of the start of any delays to the Critical Path
that are caused by actions or inactions that were not within the control of the Contractor. Delay
notifications that are not provided in a letter to the Engineer, such as a delay notification in the
schedule narrative, will not be recognized as contractual notice in the determination of any Time
Extension related to the impacts to the work associated with this specific alleged delay. Should such
delay continue for more than one (1) week, the Contractor shall note it in the Schedule Narrative
until the delay is no longer impacting the Critical Path for the completion of the Contract Milestones.
The Engineer will evaluate the alleged delay and its impact and will respond to the Contractor within
ten (10) Calendar Days after receipt of a notice of delay.
B. Time Entitlement Analysis
A Time Entitlement Analysis (TEA) shall consist of a descriptive narrative, prepared in
accordance with Subsection 722.62.A - Narratives, and an as-built CPM schedule, which may be in
the form of a schedule fragnet ( that has been developed from the project’s Contract Progress
Schedule of Record, and illustrates the impact of a delay to the Critical Path, Contract Milestones
and/or Contract Completion Date as required in Subsection 8.10 - Determination and Extension of
Contract Time for Completion. TEAs shall also be used to determine the schedule impact of
proposed Extra Work Orders (EWO) as also required in Subsection 8.10.
TEAs shall be prepared and submitted in accordance with the requirements of Subsections
722.61 - Schedule Content and Preparation Requirements and 722.62 - Submittal Requirements and
shall be based on the Contract Progress Schedule of Record applicable at the start of the delay or
impact from an EWO. A TEA fragnet must start with a specific new activity describing the work
contained in either a Notice of Delay previously submitted to the Department per Subsection
722.64.A - Notice of Delay or an EWO.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 25
SECTION 722 (Continued)
TEAs shall be submitted:
1. as part of any Extra Work Order that may impact Contract Time,
2. with a request for a Time Extension,
3. within fourteen (14) Calendar Days after a request for a TEA by the Engineer for any other
reason.
A TEA shall be submitted to the Engineer before any Time Extension is granted to the
Contractor. Time Extensions will not be granted unless the TEA accurately reflects an evaluation
of all past delays and the actual events that occurred that impacted the Critical Path. The TEA must
also demonstrate a plan for the efficient completion of all of the remaining work through an
optimized CPM Schedule. The analysis shall include all delays, including Contractor-caused delays,
and shall be subdivided into timeframes and causes of delays.
TEAs shall incorporate any proposed activities, logic ties, resource considerations, and activity
costs required to most efficiently demonstrate the schedule impacts in addition to detailing all
impacts to existing activities, logic ties, the Critical Path, Contract Milestones and the Contract
Completion Date. In addition, TEAs shall accurately reflect any changes made to activities, logic
ties, restraints and activity costs, necessitated by an Extra Work Order or other schedule impact, for
the completion of the remaining work. The Contractor shall provide TEAs that demonstrate that all
delays have been mitigated to the fullest extent possible without requiring an Equitable Adjustment
to the original bid basis.
All TEAs shall clearly indicate any overtime hours, additional shifts and the resource that are
proposed to be incorporated in the schedule. The Engineer shall have final discretion over the use
of overtime hours and additional shifts. The Engineer shall have the right to require that overtime
hours and/or additional shifts be used to minimize the duration of Time Extensions if it is determined
to be in the best interest of the Department to do so.
When accepted, the changes included in a TEA shall be incorporated into the next Contract
Progress Schedule per the requirements of Subsection 722.63.C - Contract Progress Schedules /
Monthly Updates.
During the review of any TEA, all Contract Progress Schedules shall continue to be submitted
as required.
The Engineer may request that the Contractor prepare a Proposal Schedule or a Recovery
Schedule to further mitigate any delays that are shown in the accepted TEA/Contract Progress
Schedule.
C. Recovery Schedules
The Contractor shall promptly report to the Engineer all schedule delays during the prosecution
of the Work. Except as otherwise designated by a Contract Modification, no Contract Progress
Schedule that extends performance beyond the Contract Time and/or beyond any Contract Milestone
shall be approved by the Engineer. The Contractor shall submit a Recovery Schedule within fourteen
(14) Calendar Days of a Contract Progress Schedule submission that shows failure to meet the
Contract Dates. This requirement is critical to the Department’s ability to make informed decisions
regarding Contract Time and costs.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 26
SECTION 722 (Continued)
During the prosecution of the Work, should the Contractor’s progress on a critical operation
clearly not meet anticipated production, without cause by fault of the Department, or should a critical
activity or series of activities not be staffed in accordance with the Contractor’s approved Baseline
Schedule resource planning, the Contractor shall be obligated to recover such delay. Recovery
Schedules shall be prepared and submitted in accordance with Subsections 722.61 - Schedule
Content and Preparation Requirements and 722.62 - Submittal Requirements within fourteen (14)
Calendar Days of any of the cases listed above.
Recovery Schedules shall clearly indicate any proposed overtime hours, additional shifts, and
the resources that are proposed to be incorporated in to the schedule. The Engineer shall have final
discretion over the use of overtime hours and additional shifts and shall have the right to require that
overtime hours and/or additional shifts be used to minimize the duration of Time Extensions, without
additional compensation for any Contractor delays, if it is determined to be in the best interest of the
Department to do so.
During the review of any Recovery Schedule, all Contract Progress Schedules shall continue to
be required every month.
The Engineer may request that the Contractor prepare a Recovery Schedule to further mitigate
any delays that are shown in an accepted TEA/Contract Progress Schedule.
Changes represented in accepted Recovery Schedules shall be incorporated into the next
Contract Progress Schedule.
D. Proposal Schedules
A Proposal Schedule is an alternative schedule used to evaluate proposed changes to the Contract
scope or significant alternatives to previously approved approaches to complete the Work, which
may include changes to activity durations, logic and sequence. For Types A and B Schedules, the
Proposal Schedule shall be cost and resource-loaded.
A Proposal Schedule may be requested by the Department at any time or may be offered by the
Contractor. The Engineer may request that the Contractor prepare a Proposal Schedule to further
mitigate any delays that are shown in an accepted TEA/Contract Progress Schedule.
The Contractor shall submit the Proposal Schedule within thirty (30) Calendar Days of a request
from the Department.
The Proposal Schedule shall not be considered a Schedule of Record until the logic, durations,
narrative and basis of the Proposal Schedule have been accepted by the Engineer. If the Proposal
Schedule took the form of a fragnet, it must be incorporated into the Contract Progress Schedule of
Record showing the current progress of all other activities and the impacts/results of the changes
made by the Proposal Schedule before the Proposal Schedule is accepted by the Department.
Proposal Schedules shall clearly indicate any proposed overtime hours, additional shifts, and the
resources that are proposed to be incorporated in the schedule. The Engineer shall have final
discretion over the use of overtime hours and additional shifts.
Changes represented in accepted Proposal Schedules shall be incorporated into the next Contract
Progress Schedule. During the review of any Proposal Schedule, all Contract Progress Schedules
shall continue to be required every month.

COMPENSATION
722.80 Method of Measurement and Basis of Payment (Types A, B, C and D)
The Special Provisions will specify the fixed-price amount to be paid to the Contractor for the
Project Schedule requirements contained herein. Each bidder shall include this lump-sum, fixed-
price bid item amount in his/her bid. Failure to do so may be grounds for the rejection of the bid.
All required schedule-related work, including, but not limited to computers, computer software,
the planning and coordination with utilities, training, schedule preparation and schedule submittals
will be paid for under the fixed price amount.
This fixed price amount is for payment purposes only and is separate from what the Department
considers to be the Contractor’s General Condition costs. If the Contractor deems it necessary to
include additional costs to provide all of the requirements of this section, these additional costs shall
be included in the Contractor’s overall bid price.
Twenty percent (20%) of this pay item will be paid upon the Engineer’s acceptance of the
Contractor’s Baseline Schedule, prepared and submitted in accordance with Subsection 8.02.C.
The remaining eighty percent (80%) of this pay item will be paid in equal monthly installments
distributed across the Contract Duration from Notice to Proceed (NTP) to Contractor Field
Completion (CFC), less the 2 months required for the submittal and review of the Baseline Schedule
in accordance with the following formula:
Remaining Fixed Price amount (80% of Item 100.)
Monthly Payment =
Contract Duration in whole months – 2 months
The timely and accurate submission of the Baseline Schedule is critical to the Contract and the
Department’s ability to make informed decisions. Only payments under Item 740 - Engineer’s Field
Office and Item 748 – Mobilization will be made until the Baseline Schedule is accepted by the
Engineer.

SECTION 722 (Continued)
No payment for any other pay item will be processed beyond seventy-five (75) Calendar Days
from Notice to Proceed (NTP) until the Baseline Schedule is accepted by the Engineer. Until the
Engineer’s acceptance of the Baseline Schedule, the combined total of all payments made to the
Contractor will be limited to an amount no greater than the total price for Item 748 - Mobilization
or 3% of the contract price, whichever is less.
All Contract Progress Schedule Updates submitted later than ten (10) Calendar Days after the
CQE (Contract Quantity Estimate) completion date, or greater than forty (40) Calendar Days from
the Data Date of the previous submission, will be deemed to be no longer useful and will not qualify
for payment. Late submittal of missed Contract Progress Monthly Updates will not result in recovery
of the previously forfeited portion of the Schedule of Operations Fixed Price Payment Item.
Failure to submit schedules as and when required may result in the forfeiture of that portion of
the Schedule of Operations Fixed Price Payment and/or the withholding of the full or partial CQE
payments by the Engineer.
Failure to submit schedules that are acceptable to the Engineer may result in the forfeiture of that
portion of the Schedule of Operations Fixed Price Payment and/or the withholding of the full or
partial CQE payments by the Engineer.
The Schedule of Operations pay item will be adjusted to pay for only the actual quantity of
schedules that have been submitted in accordance with this section.
The Contractor's failure or refusal to comply with the requirements of this Section shall be
reasonable evidence that the Contractor is not prosecuting the Work with due diligence and may
result in the withholding of full or partial payments by the Engineer.
Should there be a Time Extension granted to the Contractor, the Engineer may provide an
Equitable Adjustment for additional Contract Progress Schedule Updates at intervals directed by the
Engineer. Item 100. will be the basis for this Equitable Adjustment.

VALUE ENGINEERING CHANGE PROPOSAL
This Subsection defines the conditions and requirements which apply to Value Engineering
Change Proposals (“VECPs”). The purpose of this provision is to encourage the Contractor to
propose changes in certain project requirements that will maintain the project’s functional
requirements at a savings in contract time, contract price, or both. The net savings obtained by
using a VECP that meets the conditions and requirements set forth here will be shared by the
Contractor and MassDOT.
VECP’s under this provision are to be initiated, developed and submitted to MassDOT by the
Contractor. The VECP must show the contemplated changes to the Drawings, Specifications and
other requirements in the Contract. When a VECP submitted pursuant to this section is fully
accepted by MassDOT, the VECP will be implemented by the Contractor and paid using the
current cost and resource loaded schedule. Contractor shall demonstrate that the VECP is equal to,
or better than, the original design or material; that there is an interest in public safety within the
VECP; that there is a life-cycle cost benefit; and/or that end users will benefit from the shortened
schedule. VECPs shall be consistent with the MassHighway/MassDOT Standard Specifications
for Highways and Bridges and other applicable reference documents and directives. Any proposed
deviation from these documents will need to be clearly identified in the VECP Proposal
Documents, and must be approved by MassDOT’s Chief Engineer before accepting this VECP.
A. In order to be considered for MassDOT review each VECP shall:
1. Be clearly labeled pursuant to this Subsection;
2. Yield a net savings at least two hundred and fifty thousand (250,000.00) Dollars and/or
a net saving of contract completion duration of at least three (3) months;
3. The proposed changes to contract items must:
a. maintain the specified items’ required functions (service life, reliability);
b. meet applicable safety regulations and codes;
c. material substitutions must be in accordance with DOT prequalified/preapproved
products and must be tested in accordance with standard material specs/testing
methods ( and considering all relevant environmental, load, and other relevant
factors);
d. show economy of operation, ease of maintenance, ease of construction, and
necessary standardized features and appearance; and
4. Shall not require an extension of Contract Time or Contract Milestones, with the
exception of cases when there are anticipated significant cost saving.

Project No. 606555
A00801 - 30
VALUE ENGINEERING CHANGE PROPOSAL (Continued)
The thresholds above are considered to be a general guideline. MassDOT will consider VECPs
outside of these thresholds if a significant benefit is demonstrated. Additionally, notwithstanding
this VECP process, MassDOT will consider minor revisions in the form of a Contract
Modification.
Further, any VECP submitted shall be in sufficient detail to clearly define the proposed change.
The Contractor's failure to provide information of the type, detail and in a format to facilitate the
MassDOT's review, may be grounds for rejection of the VECP. Additionally, the Contractor will
not be entitled to any equitable adjustment or increased Time, due to any aspect of any of the
proposed VECP including permitting, right of way, utility coordination or delayed responses by
MassDOT. If, after the progression of the work associated with the executed Contract Modification
for the VECP, any additional costs are realized by the Contractor or any of the sub- consultants,
sub-contractors, or suppliers, the Contractor shall be obligated to pay for any and all costs.
B. The following initial items shall be provided by the Contractor for MassDOT’s review.
Items 1-6 need to be submitted prior to the start of MassDOT’s review of the VECP and
item 7 is an important consideration for the pricing of the VECP and the timeline of the
proposed VECP schedule.
1. VECP Description: A description of the difference between the existing and the
proposed Contract requirements, and the comparative advantages and disadvantages of
each;
2. VECP Change Listing: A listing of the Contract requirements that will need to be
changed, modified, or reviewed as well as the proposed Contract document changes in
the Instructions to Bidders, Contract, Standard Specifications, General Requirements
and Special Provisions required by the VECP.
3. Construction Schedule Update: Any changes in the Contract Time(s) or Contract
Milestone(s), that will result from acceptance of the VECP, shall be accompanied by a
contemporaneous schedule analysis (i.e, the Contractor’s baseline schedule
submission, all past/required monthly schedule updates, a detailed assessment of all
past delays, and a resource loaded Critical Path Method schedule as specified in
Section 8.0 / Subsection 8.02 of this Contract) of the projected Work that remains
including the proposed VECP related schedule changes (inclusive of the timeline to
review accept the VECP and the timeline for implementing the design changes) in the
remaining work. This shall be submitted in the form of a Proposal Schedule until the
VECP has been formally accepted. Note: All of this information is to be updated,
recertified, and formally accepted by MassDOT before final acceptance of this this
VECP is issued.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 31
VALUE ENGINEERING CHANGE PROPOSAL (Continued)
4. Date for MassDOT’s Acceptance: A statement that clearly justifies the date by which
the VECP must be accepted to obtain the maximum price reduction, noting any effect
upon the Contract Time(s) and/or Contract Milestone(s). This statement must include
a narrative that demonstrates the most recent construction schedule has been utilized to
justify that proposed acceptance date (e.g. “in order to start to fabricate critical
materials, authorization must be provided to work on the shop drawings by no later
than [date]”). The Contractor should allow for at least sixty (60) to ninety (90) days
for acceptance by MassDOT once all of the VECP documentation has been provided.
Acceptance shall mean that MassDOT has received a finalized and executed contract
modification. However, this is a proposed Contract change.
The Contractor is fully obligated to progress the Work of the original Contract and
MassDOT is not liable for any delays or costs that may occur in the review phase of
any VECP proposal.
5. Cost and Savings Estimates: A detailed estimate of the anticipated net savings,
calculated as follows:
a. Original Scope: Isolate the cost of performing the original contract construction
activities, in accordance with the original Contract Documents, as originally bid by
the Contractor, that are anticipated to be superseded by the VECP. This cost is to
include any original contract scope that is anticipated to be altered or eliminated
by the VECP such as, shop drawing preparation, inspection work, testing,
maintenance of traffic, or any other original contract costs, that have yet to have
been performed at the time of this VECP submission.
b. New VECP Scope: Calculate the cost of performing the comparable construction
activities associated with the VECP.
c. Contractor’s Engineer & Inspection: Calculate the cost of engineering, inspection,
and design work by the Contractor’s Engineer/Designer. This should be a realistic
estimate of the costs of any required engineering, design and review work by the
Contractor’s Engineer.
d. MassDOT’s Costs: MassDOT's estimate of costs to perform engineering/design
reviews, cost estimate reviews, schedule reviews, and any other administrative costs
to review and recommend implementation of the proposed VECP. (including all
anticipated increased costs to MassDOT on other Contracts and all anticipated
follow-on increased costs to MassDOT, if any) as provided by MassDOT.
MassDOT’s estimated costs must be included the VECP calculation and will be
provided by MassDOT in support of the VECP evaluation process.
e. Other Costs: Estimated costs associated with any revisions to other project related
costs, such as Environmental Permits or Right of Way acquisitions, including other
agency or municipality costs, as provided by MassDOT.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 32
VALUE ENGINEERING CHANGE PROPOSAL (Continued)
Net Savings:
The net savings to be split between MassDOT and the Contractor shall be calculated
using the items above as follows: a - (b+c+d+e) = net savings
6. The Contractor shall also provide:
a. A proposed Change Order, which explains and justifies any required Equitable
Adjustment in the Contract Price.
b. The Contractor's actual costs expended for developing the VECP as of the date of
the VECP submission;
7. Design Changes and Drawings: The costs that are outlined above should be inclusive
of the following design and engineering responsibilities.
a. Design changes shall be prepared and stamped by the Contractor’s professional
designer and/or engineer. In addition, in the development of the VECP; the
Contractor is responsible for anticipating and managing all aspects associated with
any VECP design work that must be performed by a licensed Engineer.
b. The Contractor’s engineer must analyze and stamp all components of any aspect of
the project that has been redesigned, changed, or altered as a result of this VECP.
c. The Contractor’s engineer shall provide all calculations and supporting
design/engineering documentation that was utilized to develop the changes and
stamped drawings. These will be used by MassDOT’s Designer-of-Record to
review the VECP changes. The Contractor is limited to selecting only those
engineer’s that have been pre-qualified by MassDOT’s A&E Board.
d. MassDOT’s Designer-of-Record will review and respond to all completed design
submissions related to this VECP within thirty (30) calendar days, unless
determined to be a non-critical path item.
e. MassDOT will be responsible for estimating and managing MassDOT’s Designer-
of-Record during the VECP review and implementation. Should any significant
conflicts arise, between the Contractor’s Engineer and MassDOT’s Designer-of-
Record, the DOT and the Contractor will work expeditiously to resolve the conflict.
Should this type of conflict continue for greater than five (5) days, the Contractor
is to bear all financial and time related impacts of such delay and must seek to
resolve the design conflict, in an acceptable manner to MassDOT. The resolution
of this conflict will be funded at the Contractor’s expense – exclusive of the net
saving that was agreed to at the execution of the contract modification for this
VECP.
f. The Contractor’s Engineer may also be required to inspect the construction work.
The Contractor is to include such anticipated inspection costs in the initial VECP.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 33
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.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 34
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.

(Supplementing Subsections 7.01(D) Plant Pest Control and 7.13 Protection and Restoration of
Property)
The Contractor shall ensure that no invasive plant species, as defined and listed by the
Massachusetts Invasive Plant Advisory Group, are introduced or moved around the site by
construction activities either by improperly cleaned construction equipment or importation of
infected materials such as borrow, compost, nursery stock, seed, or hay bales. Corrective
measures, if necessary, shall be made by the Contractor as directed by the Engineer. The
Contractor shall be solely responsible for all costs associated with ensuring that invasive species
are not introduced or moved around the site by construction activities and for all corrective
measures required for as long as necessary to eliminate the introduced invasive plant species and
prevent re-establishment of same.
EMERALD ASH BORER ADVISORY
To the extent possible, all trees and brush shall be disposed on site, typically chipped and spread
in place. When trees or brush must be removed, such as in urban, or otherwise populated areas,
Contractor shall identify proposed location for disposal, and provide written notification to the

Mains
The chlorinated water is to remain in the new pipeline for at least 24-hours. After a contact time
of 24-hours there should be a free chlorine concentration of not less than 10 mg/L (PPM).
During this period, proper precautions are to be taken to prevent this chlorinated water from
flowing back into the existing system.
All valves and hydrants within the treated section shall be operated to ensure disinfection of the
appurtenances.
The Tablet Method consisting of placing calcium hypochlorite granules or tablets in the water
main as it is being installed and then filling the main with potable water and allowing it to set for
a contact period is not acceptable.
The interior of all pipe, fittings and valves used in making a repair or tie-in shall be swabbed or
sprayed with a one percent (1%) hypochlorite solution before they are installed.
Final Flushing
Following the chlorination period, all treated water shall be flushed from the lines at their
extremities and replaced with water from the distribution system.
Flushing the main is to be accomplished at as high a velocity as possible consistent with the
ability of the Contractor to collect the discharge water for proper disposal.
All treated water flushed from the lines shall be disposed of by discharging to the nearest
sanitary sewer or by other approved means provided in AWWA C651 and acceptable to the City.

ITEMS 302.06 through 384. (continued)
Flushing shall be done in strict conformance with all applicable local, state and federal
regulations. No discharge of chlorinated water to any storm sewer or natural watercourse will be
allowed.
Bacteriological analyses
After the 24-hour disinfection period and all chlorine solution has been thoroughly flushed, the
bacteriological sampling and analysis of the replacement water may then be performed.
Bacteriological sampling shall be made by the Contractor’s competent person(s) in full
accordance with AWWA C651- Section 5, Bacteriological Tests and under the supervision of the
Engineer.
Analysis shall be performed by an independent commercial laboratory certified by the State
Department of Environmental Protection and U.S. Environmental Protection Agency for
analyzing public drinking water supplies. All results shall be provided to the Engineer for
review.
Two consecutive sets of acceptable samples, taken at least 24-Hours apart, are required prior to
placing the main into service. Failure of any one of the bacteriological test samples shall require
re-chlorination and retesting by the Contractor.
The line shall not be placed in service until the bacteriological requirements of AWWA C651 are
met.
Hydrostatic Testing
For water mains, the pressure test shall not be conducted until the new main has been flushed
clean, disinfected in accordance with paragraph 12 and the chlorinated water properly disposed
of. After acceptable completion of the water system disinfection, the Contractor may commence
pressure testing of the new water main.
Run pressure test and leakage test simultaneously in accordance with ANSI/AWWA C600.
Test pressure shall not be less than 200 PSI. Test pressure shall not exceed pipe or thrust-
restraint design pressures.
The hydrostatic test shall be of at least 2-hour duration or until such time as the Engineer
indicates acceptance of the pipeline.
Test pressure shall not vary by more than ±5 psi (35 MPa or 0.35 bar) for the duration of the test.
On pipelines where the elevation along the route of construction varies substantially, the
Engineer reserves the right to valve off and test portions of the line. On extensive construction
jobs, the Engineer reserves the right to require the testing of individual portions of the line as
construction proceeds rather than await completion of the entire project in order to undertake a
pressure or leakage test.

A00801 - 64
ITEMS 302.06 through 384. (continued)
Do not operate valves in either direction at differential pressure exceeding the rated valve
working pressure. Use of a test pressure greater than the rated valve pressure can result in
trapped test pressure between the gates of a double-disc gate valve. For tests at these pressures,
the test setup should include a provision, independent of the valve, to reduce the line pressure to
the rated valve pressure on completion of the test. The valve can then be opened enough to
equalize the trapped pressure with the line pressure, or fully opened if desired.
Test pressure shall not exceed the rated pressure of the valves when the pressure boundary of the
test section includes closed, resilient-seated gate valves or butterfly valves.
No pipeline is to be placed under pressure or subjected to hydrostatic pressure until at least 5
days have elapsed after the concrete thrust blocks have been installed. If high early strength
concrete is used in the concrete thrust blocks, the hydrostatic pressure can be applied to the main
after 2 days have elapsed from time of construction of the thrust blocks.
The Contractor will be allowed to complete backfilling as hereinbefore specified, prior to
undertaking the leakage and pressure tests. Backfilling prior to conducting tests will be at the
option of the Contractor with the exception of intersections, driveways, crosswalks and other
such locations where holding open the trench may adversely affect the public.
Pipelines may be subjected to hydrostatic pressure and inspected for leakage at any convenient
time after the trench has been partially backfilled. Partial backfilling shall consist of filling along
the center of the pipe length and leaving the joint open for inspection.
Operation of Existing Water System
Do not operate any valve or other control device on the existing water system for any purpose.
Do not make any tap or cut-in to the existing water system without the approval of the Engineer
and unless an authorized representative of the Owner is present.
When the Contractor's operations require the adjustment of any hydrant, valves, or other control
device on the existing system, the Owner will provide authorized personnel for the purpose of
supervising the operation of these control devices. Provide the personnel for the operation of
these devices.
Preparation
Conduct connections to the existing system under the Engineer’s direction.
Foreign materials left in pipelines during installation often results in valve or hydrant seat
leakage during pressure tests. Thorough flushing is recommended prior to a pressure test by
partially opening and closing valves and hydrants several times under expected line pressure,
with flow velocities adequate to flush foreign material out of the main, valves and hydrants.

Procedure
On completion of the pipeline or any valved section thereof, fill pipeline with water and test.
Draw water from the existing water system under the direction of the Engineer and the Water
Department.
Before applying the specified test pressure, expel air completely from the pipe, valves, and
hydrants. If permanent air vents are not located at all high points, install corporation cocks at
such points so that the air can be expelled as the line is filled with water. After all the air has
been expelled, close the corporation cocks and apply the test pressure. At the conclusion of the
pressure test, either remove and plug or leave in place the corporation cocks at the discretion of
the Owner.
Slowly fill each valved section of pipe with water, and apply the specified test pressure by means
of a pump connected to the pipe in a manner satisfactory to the Engineer. Valves shall not be
operated in either the opening or closing direction at differential pressures above the rated
pressure. The system shall be stabilized at the test pressure before conducting the leakage test.
Examination Under Pressure
Examine exposed pipes, fittings, valves, hydrants, and joints carefully during the test.
Repair or replace any cracked or defective pipe, fittings, valves, hydrants, or joints that are
discovered following the pressure tests with sound material, and repeat the test until it is
satisfactory to the Engineer.
Leakage Test
Leakage is defined as the quantity of water that must be supplied into the newly laid pipe, or any
valved section thereof to maintain pressure after the pipe has been filled with water and the air
has been expelled. Testing shall include all hydrants and hydrant branches. Leakage shall not be
measured by a drop in pressure in a test section over a period of time.
No pipe installation will be accepted if the leakage is greater than that determined by the
following formula:
000,148
PSD=L
L = allowable leakage, in gallons per hour
S = length of pipe tested, in feet
D = nominal diameter of the pipe, in inches
P = average test pressure during the leakage test, in pounds per square inch (gauge)
This formula is based on an allowable leakage of 10.5 gpd/mi/in of nominal diameter at a
pressure of 150 psi.
Massachusetts Department of Transportation Highway Division
Project No. 606555
A00801 - 66
ITEMS 302.06 through 384. (continued)
When testing against closed metal-seated valves, an additional leakage per closed valve of
0.0078 gph/in. of nominal valve size will be allowed.
When hydrants are in the test section, the test shall be made against the closed main valve in the
hydrant.
Acceptance of Installation - acceptance will be determined on the basis of allowable leakage. If
any test of laid pipe discloses leakage greater than that specified in this section, locate and make
approved repairs as necessary until the leakage is within the specified allowance at no additional
cost to the Owner.
Visible leaks are to be repaired, regardless of the amount of leakage.

(g) A means of effectively limiting the amount of dust escaping from the milling and removal
operation in accordance with local, State, and Federal air pollution control laws and
regulations.
When milling smaller areas or areas where it is impractical to use the above described equipment,
the use of a smaller or lesser-equipped milling machine may be permitted when approved by the
Department.
Sweeper Equipment Requirements
The Contractor shall provide a sufficient number of mechanical sweepers to ensure that the milled
surface is free of millings and debris at the end of each day’s milling operations. Each sweeper
shall be equipped with a water tank, spray assembly to control dust, a pick-up broom, a dual gutter
broom, and a dirt hopper. The sweepers shall be capable of removing millings and loose debris
from the textured pavement.
Milling Operations
The milling operations shall be scheduled to minimize the duration and placement of traffic on the
milled surface. The milling operations shall not proceed more than 3 miles ahead of the paving
operations. Under no circumstances shall the milled surface be left exposed to traffic for a period
exceeding seven days. The Department may allow the Contractor to adjust the above limitations
on milling production when necessary.
The Contractor shall coordinate milling and paving operations to minimize the exposure of milled
surfaces to traffic. The Contractor shall ensure that milled surfaces are overlaid in a timely manner
to avoid damage to the pavement structure. Any damage to the pavement structure resulting from
extended exposure of the milled surface to traffic shall be repaired as directed by the Department
at the Contractor’s expense.
The existing pavement shall be removed to the average depth shown on the plans, in a manner that
will restore the pavement surface to a uniform cross-section and longitudinal profile. The
longitudinal profile of the milled surface shall be established using a 30-foot mobile ski, mobile
string line, or stationary string line. The cross-slope of the milled surface shall be established by a
second sensing device or by an automatic cross-slope control mechanism. The Contractor will be
responsible for providing all grades necessary to remove the material to the proper line, grade,
cross section, superelevation, and transitions shown on the plans or as directed by the Department.
The requirement for automatic grade or slope controls may be waived by the Department in

Special Concrete Finishing
After completion of the primary floating, the finish the entire surface as follows:
Color Hardener shall be applied evenly to the plastic surface by the dry-shake method
using a minimum of 64 lbs and a maximum of 75 lbs per 12 square yard. It shall be
applied in two or more shakes, floated after each and troweled only after the final
floating.
Fresh concrete shall be carefully and continuously monitored and tested during partial
setting up so that proper consistency for patterning is achieved. Air temperature,
humidity, wind conditions, and other factors affecting setting rate shall be considered in
determining the start of patterning operations.
Release agent shall be applied evenly to surface.
While the concrete is still in the plastic stage of set, the imprinting tools shall be applied
to create the surface pattern. The long axis of the running bond pattern shall be
perpendicular to the adjacent travel lanes.
Full patterns shall be used to the maximum extent possible. Care shall be taken to ensure
continuity of the pattern and to maintain proper relationships to direction of travel, edges,
cut route, curbs, and other opportunities.
Where full patterns cannot be used, such as at corners, narrow areas, angles, ramps, or
obstructions, hand detailing tools and methods shall be used to continue the intended
pattern to the limit of the area. The Filler tools or hand methods shall match as closely
as possible the pattern, color, and texture of the full pattern area.
Carefully lift and remove the polyethylene sheet.
At all edges of globes, hooks of curbing, and principal obstructions, smooth and finish
the patterned art concrete with a metal edging tool, having a 3 inch plate width and a ½
inch radius. A principal obstruction shall be, for example, a light or signal standard, catch
basin, manhole, or planting area, but shall not be a water gate, fire hydrant, parking
meter, sign post, or similar incidental opportunity.
Once the concrete has attained a compressive strength of 3,000 psi (and cured for a minimum of
twenty-four (24) hours), the surface of the concrete shall be carefully power washed to remove
any debris without removing the release agent and thereafter sealed.
Repairs and Protection
Protect concrete from damage until acceptance of work and exclude traffic from pavement until
the concrete has attained a compressive strength of 3,000 psi and at least 1 day of curing time. The
pavement shall be kept free of stain and other damage. Pavement shall be swept and washed free
of stains, discolorations, dirt, and other foreign material just prior to final inspection. The Engineer
shall determine when the concrete shall be opened to traffic.

ITEM 756. NPDES STORMWATER POLLUTION PREVENTION PLAN LUMP SUM
This Item addresses the preparation and implementation of a Storm Water Pollution Prevention
Plan required by the National Pollutant Discharge Elimination System (NPDES) and applicable
Construction General Permit (CGP) issued by the U.S. Environmental Protection Agency (EPA).
Pursuant to the Federal Clean Water Act, construction activities which disturb one acre or more
are required to apply to the EPA for coverage under the NPDES General Permit for Storm Water
Discharges from Construction Activities. On February 16, 2012 (77 FR 12286), EPA issued the
final NPDES Construction General Permit (CGP) for construction activity. The Contractor shall
be fully responsible for compliance with the CGP. Should a fine or penalty be assessed against it,
or MassDOT, as a result of a local, state, or federal enforcement action due to non-compliance
with the CGP, the Contractor shall take full responsibility.
The NPDES CGP requires the submission of a Notice of Intent (NOI) to the EPA prior to the start
of construction (defined as any activity which disturbs land, including clearing and grubbing).
There is a 14-day review period commencing from the date on which EPA enters the
Notice into their database. The Contractor is advised that, based on the review of the NOI, EPA
may require additional information, including but not limited to, the submission of the Storm
Water Pollution Prevention Plan (SWPPP) for review. Work may not commence on the project
until final authorization has been granted by EPA. Any additional time required by EPA for review
of submittals will not constitute a basis for claim of delay.
In addition, if the project discharges to an Outstanding Resource Water, vernal pool, or is within a
coastal ACEC as identified by the Massachusetts Department of Environmental Protection (DEP),
a separate notification to DEP is required. DEP may also require submission of the Storm Water
Pollution Prevention Plan for review and approval. Filing fees associated with the notification to
DEP and, if required, the SWPPP filing to DEP shall be paid by the Contractor.
The CGP also requires the preparation and implementation of a SWPPP in accordance with the
afore-mentioned statutes and regulations. The Plan will include the CGP conditions and detailed
descriptions of controls of erosion and sedimentation to be implemented during construction. It is
the responsibility of the Contractor to prepare the SWPPP to meet the requirements of the most
recently issued CGP. The Contractor shall submit the Plan to the Department for approval at least
4 weeks prior to any site activities. It is the responsibility of the Contractor to comply with the
CGP conditions and the conditions of any state Wetlands Protection Act Order, Water Quality
Certification, Corps of Engineers Section 404 Permit and other environmental permits applicable
to the project and to include in the SWPPP the methods and means necessary to comply with
applicable conditions of said permits (reference to Part 9.1.1 of the 2012 CGP).
It is the responsibility of the Contractor to complete the SWPPP in accordance with the EPA CGP,
provide all information required, and obtain any and all certifications as required by the CGP. Any
amendments to the SWPPP required by site conditions, schedule changes, revised work,
construction methodologies, and the like are the responsibility of the Contractor. Amendments
will require the approval of the Department prior to implementation.
Massachusetts Department of Transportation Highway Division
Proposal No. 606555
A00801 - 97
ITEM 756. (continued)
Included in the CGP conditions is the requirement for inspection of all erosion controls and site
conditions on a weekly basis as well as after each incidence of rainfall exceeding 0.25 inches in
twenty-four hours. For multi-day storms, EPA requires that an inspection must be performed
during or after the first day of the event and after the end of the event. The CGP requires that
inspections be performed by a qualified individual. MassDOT requires proof of completion of a
4-hour minimum sedimentation and erosion control training class current to the latest CGP. This
individual can be, but not limited to, someone that is either a certified inspector, certified
professional, or certified storm water inspector. The documentation shall be included as an
appendix in the SWPPP. The Department must approve the Contractor’s inspector. This
individual shall be on-site during construction to perform these inspections. In addition, if the
Department determines at any time that the inspector’s performance is inadequate, the Contractor
shall provide an alternate inspector. Written weekly inspection forms, storm event inspection
forms, and Monthly Summary Reports must be completed and provided to the Department.
Monthly Summary Reports must include a summary of construction activities undertaken during
the reporting period, general site conditions, erosion control maintenance and corrective actions
taken, the anticipated schedule of construction activities for the next reporting period, any SWPPP
amendments, and representative photographs.
The Contractor is responsible for preparation of the Plan, all SWPPP certifications, inspections,
reports and any and all corrective actions necessary to comply with the provisions of the CGP.
Work associated with performance of inspections is not included under this Item. The Standard
Specifications require adequate erosion control for the duration of the Contract. All Control
measures must be properly selected, installed, and maintained in accordance with manufacturer
specifications and good engineering practices. If periodic inspections or other information
indicates a control has been used inappropriately or is no longer adequate, it is the responsibility
of the Contractor to replace or modify the control for site conditions at no additional cost to the
Department. The Contractor must maintain all control measures and other protective measures in
effective operating condition and shall consider replacement of erosion controls for each
construction season.
This Item addresses acceptable completion of the SWPPP, any revisions/amendments required
during construction, and preparation of monthly reports. In addition, any erosion controls beyond
those specified in bid items elsewhere in this Contract which are selected by the Contractor to
facilitate and/or address the Contractor’s schedule, methods and prosecution of the work shall be
considered incidental to this item.
The Contractor is advised The CGP provides specific requirements for temporary and final
stabilization. This shall be incorporated into the project schedule. The permit defines specific
deadline requirements for Initial Stabilization (“immediately”, i.e., no later than the end of the next
work day following the day when earth-disturbing activities have temporarily or permanently
ceased) and for Complete Stabilization Activities (no later than 14 calendar days after the initiation
of stabilization). Stabilization criteria for vegetative and non-vegetative measures are provided in
the CGP.
Massachusetts Department of Transportation Highway Division
Proposal No. 606555
A00801 - 98
ITEM 756. (continued)
The CGP requires the submission of a Notice of Termination (NOT) from all operators when final
stabilization has been achieved, as well as removal and proper disposal of all construction
materials, waste and waste handling devices, removal of all equipment and construction vehicles,
removal of all temporary stormwater controls, etcetera. Approval of final stabilization by the
Department and confirmation of submission of the NOT will be required prior to submission of
the Department’s Final Estimate. The permittee is required to use EPA’s electronic NOI system
or “eNOI system” to prepare and submit NOT. The electronic NOT form can be found at
www.epa.gov/npdes/stormwater/cgpenoi. If approval is given by the EPA Regional Office to use
a paper NOT, the form in Appendix K of the 2012 CGP must be completed.
Measurement and Payment
Payment for all work under this Item shall be made at the Contract unit price, lump sum, which
shall include all work detailed above, including plan preparation, required revisions/addenda
during construction, monthly reports and filing fees.
Payment of 50% of the Contract price shall be made upon acceptance of the Storm Water Pollution
Prevention plan. Payment of 40% of the Contract price shall be made in equal installments for
implementation of the Stormwater Pollution Prevention plan. Payment of the final 10% of the
Contract price shall be paid upon satisfactory submissions of a Notice of Termination (NOT) when
final stabilization has been achieved.

diameter. Tube material shall be a knitted mesh with 1/8” - 3/8” openings and made of 100%
biodegradable (cotton, hemp or jute) materials. Additional tubes shall be used at the direction of
the Department.
Stakes for anchors, if required, shall be nominal 2 x 2 stakes.
Construction Methods
Tubes of compost may be filled on site or shipped. Tubes shall be placed, filled and staked in
place as required to ensure stability against water flows. All tubes shall be tamped to ensure
continuous contact with the soil. Stakes shall not puncture compost tube fabric.
The Contractor shall ensure that the filter tubes function as intended at all times. Tubes shall be
inspected after each rainfall and at least daily during prolonged rainfall. The Contractor shall
immediately correct all deficiencies, including, but not limited, to washout, overtopping, clogging
due to sediment, and erosion. The contractor shall review location of tubes in areas where
construction activity causes drainage runoff to ensure that the tubes are properly located for
effectiveness. Where deficiencies exist, such as overtopping or wash-out, additional staking or
compost material shall be installed as directed by the Department. Contractor shall remove
sediment deposits as necessary to maintain the filters in working condition. The functional
integrity of filter tubes shall be maintained in sound condition at all times. Filter tubes that are
decomposing, cut, or otherwise compromised shall be repaired or replaced as directed by the
Department and be incidental to this item. At specific locations, such as at gully points, steep

reinforced by either staked hay bales and/or silt fence at the direction of the Department. Such
reinforcing shall be incidental to the cost of this item and shall not exceed 10 percent of the overall
length of compost filter tube required for the project.
Stakes shall be removed by the Contractor when site conditions are sufficiently stable to prevent
surface erosion, and after receiving permission to do so from the Department. The Contractor shall
cut the tube longitudinally and empty the compost. The tube fabric shall be removed and properly
disposed of and the Contractor shall rake out compost so that it blends evenly and is no greater
than 1-2 inches in depth on soil substrate. Raked compost shall then be seeded with a mix
appropriate to the surrounding vegetation.

ITEMS 866.206, 866.212, 867.206 & 867.212 (continued)
Construction Methods for Installation of Groove
Prior to cutting out the grooves for all recessed lines, the Contractor shall use a chalk line or other
suitable method to layout the proposed pavement markings on the surface course so that the
Engineer can inspect the locations. Once the Engineer has inspected and approved the proposed
striping layout, the grooves for the proposed pavement markings may be cut. No pavement
grooving shall be done without the prior approval of the Engineer.
Groove position shall be a minimum of 4 inches from the edge of the pavement marking to any
longitudinal pavement joints. The groove shall not be installed on bridge joints, on drainage
structures, or in other areas identified by the Engineer. The groove shall not be installed
continuously for intermittent pavement markings, but only where markings are to be applied.
The use of gang stacked diamond cutting blades to grind a smooth square slot is required for
producing all grooves. The spacers between blade cuts shall be such that there will be less than a
10 mil rise in the finished groove between the blades. The acceptability of the surface texture will
be determined by the Engineer.
The diamond grinder shall have an articulating head so that the slots are installed correctly on
grades and super elevated sections.
Grooves that are ground deeper or wider than the specified allowable limits shall be repaired per
the direction of the Engineer at no additional cost. Grooves that are ground too shallow, too narrow,
or with unacceptable rises between blade cuts shall be reground to the correct size, depth, and
surface finish at no additional cost. Slots ground out of alignment shall be patched using an
approved method and materials.
Grooves shall be 1 inch ± ¼ inch wider than the pavement marking material. Groove depth shall
be 100 mils ±5 mils, unless otherwise approved by the Engineer. Depth shall be consistent across
the full width of the groove. Depth plates shall be provided by the Contractor to the Engineer to
assure that desired groove depth is achieved.
Grooves shall be clean, dry and free of laitance, oil, dirt, grease, paint or other foreign
contaminants. Shrouds and a vacuum apparatus shall be included as part of the grinder to remove
larger pieces of pavement that are ground out. If water is used to clean the groove or the grooving
process takes place during rainfall, a minimum of 24 hours of dry time is required prior to the
placement of pavement markings.
After the depth, width, length, and surface condition has been approved by the Engineer, an air
lance shall be used to remove fine particles from the groove. Air compressors shall initially be
blown out away from the application area to prevent compressor condensation build-up from
entering the groove. The Contractor shall prevent traffic from traversing the grooves and re-clean
grooves, as necessary, prior to application of pavement markings at no additional cost to the
Department.
All grooves must be given final approval by the Engineer prior to the placement of pavement
markings.

Construction Methods for Installation of Durable Pavement Markings
Installation of wet reflective polyurea pavement markings shall conform to the Manufacturer’s
specifications and the following:
Application rate for binder and all beads and elements shall consider final pavement surface
composition and smoothness in advance of application to ensure proper wet film thickness and
embedment of all beads and elements. The Contractor shall provide the Engineer with
documentation from the Manufacturer with all recommended application rates (and conformance
to initial dry and wet reflectivity requirements) in advance of any pavement marking installation.
The minimum uniform wet thickness for the polyurea binder shall be 25-30 mils. The line thickness
shall be met across at least the middle ⅔ of the pavement marking width. Depth plates shall be
provided by the Contractor to the Engineer to assure that desired thickness is achieved.
The finished white color shall be free from tint, with good opacity and visibility under both
daylight and artificial light. The finished yellow color shall be defined by Federal Test Standard
595 - Color Chip Number 13538, using Federal Test Standard 141 (Method 4252). The finished
lines shall be uniform in color and have clean, well-defined edges.
First and second drop beads and/or elements shall be applied in a manner that does not induce
rolling or bouncing, to ensure that exposed portions of beads are free of binder material. Beads
and elements should be embedded in the binder to a depth of approximately 50% of their diameter.
Drop rate for first drop bead or element shall be per the Manufacturer’s specifications.
Drop rate for second drop glass bead shall be 6.4-10.2 lbs. per gallon.
Newly installed pavement markings shall be protected from tracking during the setting period per
Subsection 860.63.
Incidental to the cost of these items, the Contractor shall measure the average retroreflectance of
the pavement markings, and report the results to the Engineer. The Contractor shall take
retroreflectance measurements
1.ASTM E1710 (Standard Test Method for Measurement of Retroreflective Pavement
Marking Materials with CEN-Prescribed Geometry Using a Portable Retroreflectometer);
and
2.ASTM E2177 (Standard Test Method for Measuring the Coefficient of Retroreflected
Luminance (RL) of Pavement Markings in a Standard Condition of Wetness).
The average initial retroreflectance readings shall exceed the following minimum values:
*White Markings *Yellow Markings
ASTM E1710 (Dry) 475 mcd/lux/m2 375 mcd/lux/m2
