1.2 CORRELATION AND INTENT OF THE CONTRACT DOCUMENTS 1.2.1 The intent of the Contract Documents is to include all items necessary for the proper execution and completion of the Work by the Contractor. The Contract Documents are complementary, and what is required by one shall be as binding as if required by all; performance by the Contractor shall be required only to the extent consistent with the Contract Documents and reasonably inferable from them as being necessary to produce the indicated results. All work mentioned or indicated in the Contract Documents shall be performed by the Contractor as part of the Contract unless it is specifically indicated in the Contract Documents that such Work is to be done by others. 1.2.1.1 In the event of conflict in or between the Contract Documents, the Contractor shall be held to the highest standard therein. Where compliance with two or more industry standards or set of requirements is specified, and overlapping of those different standards or requirements established different or conflicting minimums or level of quality, the most stringent requirements is intended. 1.2.1.2 In the event of a conflict between any provision or language of the Construction Contract and any provision or language of the contract documents, the provision or language of the Construction Contract shall control. In the event of any conflict or inconsistency between this contract, the Contract Documents and any Governing Laws and Building Code, the Governing Laws and Building Code shall prevail. 1.2.2 Organization of the Specifications into divisions, sections and articles, and arrangement of Drawings shall not control the Contractor in dividing the Work among Subcontractors or in establishing the extent of Work to be performed by any trade except sections designated for Filed Sub-Bids as otherwise required by law. The General Contractor and all Subcontractors shall refer to all of the Drawings, including those showing primarily the work of the mechanical, electrical, and other specialized trades, and to all of the sections of the specifications, and shall perform all Work reasonably inferable therefrom as being necessary to produce the indicated results. 1.2.3 Unless otherwise stated in the Contract Documents, words that have well-known technical or construction industry meanings are used in the Contract Documents in accordance with such recognized meanings. 1.2.4 The Drawings and Specifications are intended to supplement one another. Materials and workmanship described are not necessarily found in both. Drawings are not intended to be scaled or to act as shop drawings. Inadvertent discrepancies or omissions shown on one drawing but not on others shall not be cause for additional charges or claims. In case of discrepancies, figured dimensions shall take precedence over smaller scale drawings. Specifications shall take precedence over Drawings for quality of materials and general performance of the work. 1.2.5 Whenever an item is specified and/or shown on the Drawings by details or reference, it shall be considered typical for other items which are obviously intended to be the same even though not so designated or specifically named but do serve the same function for this project.

1.2.6 Where the terms “necessary,” “as directed,” “when directed,” “satisfactory,” good and sufficient,” “approved,” or other general qualifying terms are used on the Drawings, they are deemed to be followed by the words ‘in the opinion of the Designer” or “by the Designer” as the case may be. 1.2.7 The terms “approval,” “approved,” “approved equal,” “or equal,” or “other approved” mean as approved by the Designer. 1.2.8 Where reference is made to ASTM Specifications, it shall mean the standard specific specifications of the International Society for Testing and Materials of the most recent designation. 1.2.9 Similarly, where reference is made to Specifications, Standards or requirements of A.S.M.E. or A.S.H. & V.E., they shall mean respectively those American Society for Mechanical Engineers and the American Society for Heating and Ventilating Engineers, and shall be from the latest editions. 1.2.10 Any material specified by reference to the number, symbol, or title of a specific standard, such as a Commercial Standard, a Federal Specification, a trade association standard, or other similar standard, shall comply with the requirements in the latest revision thereof and any amendment or supplement thereto in effect on the date indicated on the specifications, except as limited, or modified in such reference. Where compliance with two or more industry standards or set of requirements is specified, and overlapping of those different standards or requirements established different or conflicting minimums or level of quality, the most stringent requirements is intended. 1.2.11 The standards referred to, except as modified in the Contract Documents, shall have full force and effect as though printed in the Contract Documents. These standards are not furnished to the Contractor for the reason that the manufacturers and trades involved are assumed to be familiar with their requirements.

The “Drawings” are the graphic and pictorial portions of the Contract Documents showing the design, location and dimensions of the Work, generally including plans, elevations, sections, details, schedules and diagrams. 2.4 Specifications. The “Specifications” are that portion of the Contract Documents consisting of the written requirements for materials, equipment, systems, standards and workmanship for the Work, and performance of related services. 2.5 Site. The word “site” shall mean the project site, the parameters of which are indicated on the Contract Drawings. 2.6 Governing Laws and Building Code. The term “governing laws and building code,” whenever used, shall mean all laws, ordinances, rules, regulations, and lawful orders of any public authority, federal, state, or local bearing on the performance of the Work and the building code or codes legally applicable to work. 2.7 Claim.

3.4 Liquidated Damages for Delay in Substantial Completion: Because both parties recognize (1) that the time for completion of this Contract is of the essence, (2) that the Owner will suffer loss if the work is not completed in accordance with the phasing requirements and within the contract time specified, plus any extensions thereof allowed in accordance with the provisions of this Contract, and (3) that there are significant delays, expense and difficulties associated with a legal proceeding to determine the actual loss suffered by the Owner if the work is not completed on time; therefore, it is agreed that the Contractor will pay the Owner, as liquidated damages, the sum of Five Hundred Dollars ($500.00) per day for each and every day thereafter that it fails to deliver such Work completed according to the requirements of the Contract Documents. Such liquidated damages shall be paid not as a penalty, but to partially cover losses and expenses to the Owner, including intangible costs and losses that are or may be impracticable to ascertain. Allowing the Contractor to continue to finish the work (or any portion of the work) after the time specified for completion of the Work shall not operate as a waiver on the part of the Owner of any of its rights under the Contract Documents or otherwise under law or equity. The Owner’s right to impose liquidated damages shall in no way prohibit or restrict the Owner’s right to bring legal action for damages in lieu of its option to impose liquidated damages from money due the Contractor, and if such money is insufficient to cover the liquidated damages, then the Contractor shall pay the amount due. 3.5 The Contractor hereby agrees that if he fails to commence the work, carryon the work with reasonable speed or stops work altogether without due cause, as determined in each case by the Town, the Town may give notice to the Contractor in writing to proceed with the work as per the schedule or to carry on the work with reasonable speed.

Upon request by the Owner, the Contractor shall make available to the Owner such audited and unaudited financial statements of the Contractor as the Owner may reasonably request. The Contractor shall promptly advise the Owner of any occurrence, event, fact, or other matter that has had, will have, or might reasonably be predicted to have a material adverse effect upon the financial condition of the Contractor.

5.2 Review of Contract and Field Conditions. Execution of the Contract by the Contractor is a representation that the Contractor has visited the site, become thoroughly familiar with all the existing conditions at the site, has taken all such conditions into consideration as they may affect the Work under his Contract, and correlated personal observations with requirements of the Contract Documents. No allowance will be made in the Contract or the Work under the Contract for failure of the Contractor to visit the site. 5.2.1 Should any omissions, error or conflict be found in the Contract Documents, during the bidding period and prior to the times set forth in the Instructions for Bidders for receipt of such inquiries, the bidders shall request in writing that such conditions be explained by the Designer in the method described therein. 5.2.2 Should the work proceed, after the discovery of errors, conflict, or omissions by the Designer and clarification has not been received from the Designer, the Contractor will be held fully responsible for replacement or correction of the affected area, as directed by the Designer, at the Contractor’s expense. 5.2.3 Before ordering any material or doing any work, each trade shall verify all measurements at this project and shall be responsible for the correctness of the same.

Any structural or mechanical changes made necessary to accommodate products or materials substituted as an "or equal” shall be at the expense of the Contractor. "Approved equal" shall mean an item with respect to which the Owner shall have issued a written statement to the Contractor to the effect that the item is, in the Owner’s opinion, equal within the meaning of this paragraph to that prescribed in the Contract Documents. 5.19.2 The Contractor shall be responsible for providing the Designer with any information and test results that the Designer reasonably requires to determine whether or not a material is equal to a material named or described in the Contract Documents. 5.19.3 Whenever the Contractor submits a material for approval as a substitute for a material named or described in the Contract Documents, such submission shall be made at least one hundred twenty (120) days prior to the date the materials will be used in the Work. In no event shall the Contractor maintain a claim for delays based upon the Designer's review of such substituted materials if the Contractor has failed to comply with the one hundred twenty (120) day submission requirement. 5.19.4 The Contractor shall save the written calculations, pricing information, and other data that the Contractor used to calculate the General Bid (the "Bid Pricing Materials") for at least six years after the Owner makes Final Payment under this Contract Agreement. No increase in the Contract Sum shall be allowed for any material later found to have been improperly rejected as not being equal unless the Contractor can show persuasive evidence that the rejection increased the Contractor's costs over those provided for in the Bid Pricing Materials, net of all savings the Contractor obtained by substituting other "or-equal" items. Without limiting the foregoing, if the Owner rejects a proposed substitution on the basis that the item is not equal and if after the

16 | P a g e

Contractor complies with the appeal procedures required by law and by the Contract Documents, the appropriate authority finds that the proposed substitution was equal, the Contract Sum may be increased only to the extent that (1) the item that the Contract Documents specifically require costs more than the item later approved as equal, (2) the Bid Pricing Materials prove that the Contractor calculated its bid using the cost of the item later found as equal, (3) any increase is reduced by any cost that the Contractor would have incurred for structural or mechanical changes necessary to accommodate the substitute item, (4) the Contractor shall not be entitled to any adjustment for overhead and profit, (5) any increase must exceed the aggregate amount that the Contractor saved using products or materials that the Owner approved as equal under this Contract Agreement. In calculating the Contractor's aggregate saving under the preceding clause (5), the Contractor shall provide the Owner with the Bid Pricing Materials and a calculation based on the Bid Pricing Materials that compare the price (stated in the Bid Pricing Materials) of each item replaced with an "or equal" item, with the cost of the approved equal item, specifically describes all costs that Contractor would have incurred making structural or mechanical changes to include within the Work the item later found to have been improperly rejected and copies of all plans, specifications, shop Drawings, and other design documents that the Owner deems necessary or desirable. 5.20 Delivery and Storage of Materials 5.20.1 Materials and equipment shall be progressively delivered to the Site so that there will be neither delay in the progress of the Work nor an undue accumulation of materials that are not to be used within a reasonable time and so that their security, quality, and fitness of the materials for the Work is preserved. 5.20.2 Materials stored off Site shall be insured and stored at the expense of the Contractor so as to guarantee the preservation of their security, quality and fitness for the Work. Without derogating from the Contractor's responsibilities in the previous sentence, when necessary to avoid deterioration or damage, material (on or off Site) shall be placed on wooden platforms or other hard clean surfaces and not on the ground and shall be properly protected. 5.20.3 Expenses for inspection of material by the Designer and/or the Owner including travel, quarters, and subsistence shall be borne by the Contractor requesting the inspection of material stored outside the Commonwealth of Massachusetts as part of the Contract Price. The policy of the Owner precludes the payment for material stored outside the boundaries of Massachusetts except in extremely limited circumstances with the express written consent of the Owner. If the Contractor requests an inspection of material stored outside the Commonwealth of Massachusetts, the Owner will initially pay for all expenses of inspecting the material incurred by the Designer and/or Owner’s personnel including travel, quarters, and subsistence. The Owner will then give Contractor an invoice for those costs and the Contractor shall submit a credit Change Order for the amount of those expenses. 5.20.4 Stored materials either at the Site or at some other location agreed upon in writing shall be so located as to facilitate prompt inspection and even though approved before storage, may again be inspected prior to their use in the Work. 5.20.4.1 All storage sites shall be restored to their original condition by the Contractor at the Contractor’s expense. 5.20.5 The Contractor shall take charge of and be liable for any loss of or injury to the materials for his use delivered to or in the vicinity of the place where the Work is being done, whether furnished by the Owner or otherwise; the Contractor shall notify the Designer as soon as any such materials are so delivered, allow them to be examined by the Designer, and furnish workers to assist therewith. 5.21 Defective and Damaged Materials 5.21.1 The Designer may reject materials if the Designer reasonably determines that such materials do not conform to the Contract Documents in any manner, including but not limited to

17 | P a g e

materials that have become damaged or deteriorated from improper storage whether or not such materials have previously been accepted. The Contractor at its own expense shall remove rejected materials from the Work. No rejected material, the defects of which have been subsequently corrected, shall be used except with the written permission of the Designer. Should the Contractor fail to remove rejected material within a reasonable time, the Designer and/or Owner may, in addition to any other available remedies, remove and/or replace the rejected material, and to deduct the cost of such removal and/or replacement from any moneys due or to become due the Contractor. No extra time shall be allowed for completion of Work by reason of such rejection. The inspection of the Work shall not relieve the Contractor of any of its obligations herein prescribed, and any defective Work shall be corrected. Work not conforming to the Contract Documents may be rejected notwithstanding that such Work and materials have been previously overlooked or misjudged by the Designer and accepted for payment. If the Work or any part thereof shall be found defective at any time before Final Acceptance of the whole Work, the Contractor shall forthwith make good such defect in a manner satisfactory to the Designer. Nothing in the Contract shall be construed as vesting in the Contractor any property rights in the materials used after they have been attached or affixed to the Work or the Site; but all such materials shall upon being so attached or affixed become a property of the Owner. 6. PAYMENT 6.1 Schedule of Values. Before the first application for payment the Contractor shall submit to the Designer and the Owner a schedule of values allocated to various portions of the Work in sufficient detail to reflect the various major components of each trade (with filed Subcontractors as well as MBE/WBE noted), including quantities when requested, aggregating the total Contract Price and divided so as to facilitate payments for work under each section of the Specifications. The schedule shall be prepared in such form and supported by such data to substantiate its accuracy as the Designer or the Owner may require. Each item in the schedule shall include its proper share of overhead and profit. When Approved by the Designer and the Owner, it shall constitute the Schedule of Values and shall be used only as a basis for the Contractor's requests for payments. 6.2 Applications for Payment. At least fifteen days before the date established for each progress payment, the Contractor shall submit to the Architect and Owner an itemized Application for Payment prepared in accordance with the schedule of values for completed portions of the Work. Such application shall be notarized, if required, and supported by such data substantiating the Contractor’s right to payment as the Owner or Architect may require, such as copies of requisitions from Subcontractors and material suppliers, and shall reflect retainage. 6.2.1 PENCIL REQUISITION: In order to expedite monthly payments during the course of the Project, the Contractor shall review with the Architect a preliminary draft of each Application for Payment before final copies the application are typed and formally submitted. The Architect shall then review the Contractor’s formal, notarized Application for Payment, supported by such data substantiating the Contractor’s Application for Payment as the Owner or Architect may require, and certify in writing the total value of Work completed, including an allowance for the value of materials delivered and suitably stored at the site at the time of such Application. 6.3 Based upon Applications for Payment submitted by the Contractor and Certificates for Payment issued by the Designer, the Owner shall make progress payments on account of the Contract Sum to the Contractor as provided below and elsewhere in the Contract Documents.

18 | P a g e

6.4 Payment to the Contractor shall be made by the Town in accordance with in accordance with M.G.L. c. 30, Sec. 39K:

Within fifteen days (30 days in the case of the commonwealth, including local housing authorities) after receipt from the contractor, at the place designated by the awarding authority if such a place is so designated, of a periodic estimate requesting payment of the amount due for the preceding month, the awarding authority will make a periodic payment to the contractor for the work performed during the preceding month and for the materials not incorporated in the work but delivered and suitably stored at the site (or at some location agreed upon in writing) to which the contractor has title or to which a subcontractor has title and has authorized the contractor to transfer title to the awarding authority, upon certification by the contractor that he is the lawful owner and that the materials are free from all encumbrances, but less (1) a retention based on its estimate of the fair value of its claims against the contractor and less (2) a retention for direct payments to subcontractors based on demands for same in accordance with the provisions of section thirty-nine F, and less (3) a retention not exceeding five per cent of the approved amount of the periodic payment. After the receipt of a periodic estimate requesting final payment and within sixty-five days after (a) the contractor fully completes the work or substantially completes the work so that the value of the work remaining to be done is, in the estimate of the awarding authority, less than one per cent of the original contract price, or (b) the contractor substantially completes the work and the awarding authority takes possession for occupancy, whichever occurs first, the awarding authority shall pay the contractor the entire balance due on the contract less (1) a retention based on its estimate of the fair value of its claims against the contractor and of the cost of completing the incomplete and unsatisfactory items of work and less (2) a retention for direct payments to subcontractors based on demands for same in accordance with the provisions of section thirty-nine F, or based on the record of payments by the contractor to the subcontractors under this contract if such record of payment indicates that the contractor has not paid subcontractors as provided in section thirty-nine F. If the awarding authority fails to make payment as herein provided, there shall be added to each such payment daily interest at the rate of three percentage points above the rediscount rate than charged by the Federal Reserve Bank of Boston commencing on the first day after said payment is due and continuing until the payment is delivered or mailed to the contractor; provided, that no interest shall be due, in any event, on the amount due on a periodic estimate for final payment until fifteen days (twenty-four days in the case of the commonwealth) after receipt of such a periodic estimate from the contractor, at the place designated by the awarding authority if such a place is so designated. The contractor agrees to pay to each subcontractor a portion of any such interest paid in accordance with the amount due each subcontractor.

The payment shall be in full less 5% retainage for furnishing all materials, supplies, labor, services, supervision, tools and equipment and use thereof. Acceptance of periodic payments by the Contractor shall constitute a waiver of claims known or knowable at the time by the Contractor except those previously made in writing and identified by the Contractor as unsettled at the time of periodic payment.

19 | P a g e

6.5 Each Application for Payment or periodic estimate requesting payment shall be accompanied by a certificate signed by each Subcontractor under pains and penalties of perjury stating that the Subcontractor has been paid all amounts due the Subcontractor on the basis of the previous periodic payment to the Contractor, or else stating the amount not so paid and the reason for the discrepancy. In the event of any such discrepancy, the Contractor shall furnish the Contractor’s own written explanation to the Owner through the Engineer. Such waiver or certificate shall be in a form acceptable to the Owner. The Contractor warrants that title to all work covered by an application for payment will pass to the Owner either by incorporation into the construction or upon the receipt of payment by the Contractor, whichever occurs first, free and clear of all liens, claims, security interests, or encumbrances, hereinafter referred to in this article as ‘liens.’ The Contractor further agrees that the submission of any application for payment shall conclusively be deemed to waive all liens with respect to set work to which the Contractor may then be entitled, provided that such waiver of the lien rights shall not waive the Contractor’s right to payment for such work. 6.6 The period covered by each Application for Payment shall be one calendar month ending on the last day of the month. 6.7 Retainage shall be withheld until Substantial Completion of the entire project. The Owner will pay ninety-five percent (95%) of the amount due the Contractor on account of progress payments. This retainage of five percent (5%), less any amount due from the Contractor for Liquidated Damages and applicable costs of the Designer, and Designer’s Consultants, and less amounts based on the established value of punch list items and any other Owner claims or back-charges against the Contractor, will be paid within sixty-five (65) days of Substantial Completion in accordance with M.G.L. c.30, §39K. Acceptance of periodic payments by the Contractor shall constitute a waiver of claims known or knowable at the time by the Contractor except those previously made in writing and identified by the Contractor as unsettled at the time of periodic payment. 6.8 If at any time there shall be evidence of any lien or other claim for which, if established, the Owner may become liable, directly or indirectly, and which is chargeable to the Contractor, the Owner may retain out of the payment then due or thereafter to become due, an amount sufficient to completely indemnify it against any such claim. If there proves to be any such claims after all the payments are made, the Contractor shall refund to the Owner all moneys that the Owner pays in discharging such claim in consequence of the Contractor’s default. 6.9 The Contractor warrants that title to all Work (including materials and equipment) covered by an Application for Payment will pass to the Owner either by incorporation in the Work or upon the receipt of payment by the Contractor, whichever occurs first, free and clear of all liens, claims, security interests or encumbrances. 6.10 Unless otherwise provided in the Contract Documents, payments shall be made on account of materials and equipment delivered and suitably stored at the site for subsequent incorporation in the Work. If approved in advance by the Owner, payment may similarly be made for materials and equipment suitably stored off the site at a location agreed upon in writing. Payment for materials and equipment stored on or off the site shall be conditioned upon compliance by the Contractor with procedures satisfactory to the Owner to establish the Owner’s

20 | P a g e

title to such materials and equipment or otherwise protect the Owner’s interest, and shall include the costs of applicable insurance, storage and transportation to the site for such materials and equipment stored off the site. 6.11 The Contractor warrants that title to all Work (including materials and equipment) covered by an Application for Payment will pass to the Owner either by incorporation in the Work or upon the receipt of payment by the Contractor, whichever occurs first, free and clear of all liens, claims, security interests or encumbrances. 6.12 The Contractor, his Subcontractors and Sub-subcontractors shall obtain prior written approval from the Owner through the Designer for permission to store materials to be incorporated in the Work, for which Progress Payments will be requested, at off-site locations. In no case shall stored materials or equipment, whether stored at the site or at some other location, be considered payment unless, in the sole judgment of the Owner, the materials or equipment are ready for and actually scheduled for prompt use. Written request for payment of stored material must be made thirty days in advance of the due date for the Application for Payment. Any and all charges for storage, including insurance, shall be borne solely by the General Contractor. Before approval, the Owner will require proper proof of insurance and a letter in which is furnished: (a) the name of the Contractor and/or the Subcontractor or Sub-subcontractor leasing the storage area; (b) the location of such leased space; (c) the leased area (the entire premises or certain areas of a warehouse given the number of floors or portions thereof); (d) the date on which the material is first stored; and (e) the value of the material stored. 6.12.1 The General Contractor, his Subcontractors and Sub-subcontractors shall notify the Designer and the Owner to inspect, at least once each month, the materials being stored at any location. 6.12.2 The General Contractor, his Subcontractors and Sub-subcontractors shall mark each sealed carton with the name of the Project and the Designer. 6.12.3 A perpetual inventory shall be maintained for all materials held in storage for which payment has been requested. 6.12.4 Payment for materials stored off site shall be at the sole discretion of the Owner. Any additional costs to the Owner resulting from storage of material off site for which payment is requested, such as, but not limited to, travel expenses and time for inspectors, shall be charged to, and paid by, the General Contractor. 6.13 The Contractor shall submit four (4) copies of its Application for Payment. 6.14 Certificates for Payment 6.14.1 The Designer will, within seven days after receipt of the Contractor’s Application for Payment, either issue to the Owner a Certificate for Payment, with a copy to the Contractor, for such amount as the Designer determines is properly due, or notify the Contractor and Owner in writing of the Designer’s reasons for withholding certification in whole or in part as provided herein.

21 | P a g e

6.14.2 The issuance of a Certificate for Payment will constitute a representation by the Designer to the Owner, based on the Designer’s evaluation of the Work and the data comprising the Application for Payment, that, to the best of the Designer’s knowledge, information and belief, the Work has progressed to the point indicated and that the quality of the Work is in accordance with the Contract Documents. The foregoing representations are subject to an evaluation of the Work for conformance with the Contract Documents upon Substantial Completion, to results of subsequent tests and inspections, to correction of minor deviations from the Contract Documents prior to completion and to specific qualifications expressed by the Designer. However, the issuance of a Certificate for Payment will not be a representation that the Designer has (1) made exhaustive or continuous on-site inspections to check the quality or quantity of the Work, (2) reviewed construction means, methods, techniques, sequences or procedures, (3) reviewed copies of requisitions received from Subcontractors and material suppliers and other data requested by the Owner to substantiate the Contractor’s right to payment, or (4) made examination to ascertain how or for what purpose the Contractor has used money previously paid on account of the Contract Sum. 6.14.3 The Designer may withhold a Certificate for Payment in whole or in part, to the extent reasonably necessary to protect the Owner, if in the Designer’s opinion the representations to the Owner required by Section 6.12.2 cannot be made. If the Designer is unable to certify payment in the amount of the Application, the Designer will notify the Contractor and Owner as provided in Section 6.12.1. If the Contractor and Designer cannot agree on a revised amount, the Designer will promptly issue a Certificate for Payment for the amount for which the Designer is able to make such representations to the Owner. The Designer may also withhold a Certificate for Payment or, because of subsequently discovered evidence, may nullify the whole or a part of a Certificate for Payment previously issued, to such extent as may be necessary in the Designer’s opinion to protect the Owner from loss for which the Contractor is responsible, including loss resulting from acts and omissions described in Section 5.8.2, because of

1. defective Work not remedied; 2. third party claims filed or reasonable evidence indicating probable filing of such

claims unless security acceptable to the Owner is provided by the Contractor; 3. failure of the Contractor to make payments properly to Subcontractors or for labor,

materials or equipment; 4. reasonable evidence that the Work cannot be completed for the unpaid balance of

the Contract Sum; 5. damage to the Owner or a separate contractor; 6. reasonable evidence that the Work will not be completed within the Contract Time,

and that the retainage currently held by the Owner would not be adequate to cover actual or liquidated damages for the anticipated delay; or

7. failure to carry out the Work in accordance with the Contract Documents. 8. failure of mechanical trade or electrical trade, or any other trade, subcontractor to

comply with mandatory requirements for maintaining record drawings. The Contractor shall check record drawings each month. Written confirmation that the record drawings are current will be required by the Designer before approval of the Contractor’s monthly payment requisition.

6.14.4 When the above reasons for withholding certification are removed, certification will be made for amounts previously withheld, and which are properly due the Contractor.

22 | P a g e

6.14.5 If the Designer withholds certification for payment under Section 6.12.3, the Owner may, at its sole option, issue joint checks to the Contractor and to any Subcontractor or material or equipment suppliers to whom the Contractor failed to make payment for Work properly performed or material or equipment suitably delivered. If the Owner makes payments by joint check, the Owner shall notify the Designer and the Designer will reflect such payment on the next Certificate for Payment. 6.14.6 A Certificate for Payment, a progress payment, or partial or entire use or occupancy of the Project by the Owner shall not constitute acceptance of Work not in accordance with the Contract Documents. ARTICLE 7: PAYMENT OF SUBCONTRACTORS 7.1 The Contractor shall make payment to subcontractors in accordance with M.G.L. c. 30, § 39F, which is quoted in this section below. For purposes of this Agreement, the word “forthwith” appearing in paragraph (1)(a) of the quoted provision shall be deemed to mean “within five (5) business days.” The Contractor shall, at the Owner’s request, furnish satisfactory evidence that all such obligations have been paid, discharged, or waived. M.G.L. c. 30, § 39F provides:

(1) Every contract awarded pursuant to sections forty-four A to L, inclusive, of chapter one hundred and forty-nine shall contain the following subparagraphs (a) through (i) and every contract awarded pursuant to section thirty-nine M of chapter thirty shall contain the following subparagraphs (a) through (h) and in each case those subparagraphs shall be binding between the general contractor and each subcontractor. (a) Forthwith after the general contractor receives payment on account of a periodic estimate, the general contractor shall pay to each subcontractor the amount paid for the labor performed and the materials furnished by that subcontractor, less any amount specified in any court proceedings barring such payment and also less any amount claimed due from the subcontractor by the general contractor. (b) Not later than the sixty-fifth day after each subcontractor substantially completes his work in accordance with the plans and specifications, the entire balance due under the subcontract less amounts retained by the awarding authority as the estimated cost of completing the incomplete and unsatisfactory items of work, shall be due the subcontractor; and the awarding authority shall pay that amount to the general contractor. The general contractor shall forthwith pay to the subcontractor the full amount received from the awarding authority less any amount specified in any court proceedings barring such payment and also less any amount claimed due from the subcontractor by the general contractor. (c) Each payment made by the awarding authority to the general contractor pursuant to subparagraphs (a) and (b) of this paragraph for the labor performed and the materials furnished by a subcontractor shall be made to the general contractor for the account of that subcontractor; and the awarding authority shall take reasonable steps to compel the general contractor to make each such payment to each such subcontractor. If the awarding authority has received a demand for direct payment from a subcontractor for

23 | P a g e

any amount which has already been included in a payment to the general contractor or which is to be included in a payment to the general contractor for payment to the subcontractor as provided in subparagraphs (a) and (b), the awarding authority shall act upon the demand as provided in this section. (d) If, within seventy days after the subcontractor has substantially completed the subcontract work, the subcontractor has not received from the general contractor the balance due under the subcontract including any amount due for extra labor and materials furnished to the general contractor, less any amount retained by the awarding authority as the estimated cost of completing the incomplete and unsatisfactory items of work, the subcontractor may demand direct payment of that balance from the awarding authority. The demand shall be by a sworn statement delivered to or sent by certified mail to the awarding authority, and a copy shall be delivered to or sent by certified mail to the general contractor at the same time. The demand shall contain a detailed breakdown of the balance due under the subcontract and also a statement of the status of completion of the subcontract work. Any demand made after substantial completion of the subcontract work shall be valid even if delivered or mailed prior to the seventieth day after the subcontractor has substantially completed the subcontract work. Within ten days after the subcontractor has delivered or so mailed the demand to the awarding authority and delivered or so mailed a copy to the general contractor, the general contractor may reply to the demand. The reply shall be by a sworn statement delivered to or sent by certified mail to the awarding authority and a copy shall be delivered to or sent by certified mail to the subcontractor at the same time. The reply shall contain a detailed breakdown of the balance due under the subcontract including any amount due for extra labor and materials furnished to the general contractor and of the amount due for each claim made by the general contractor against the subcontractor. (e) Within fifteen days after receipt of the demand by the awarding authority, but in no event prior to the seventieth day after substantial completion of the subcontract work, the awarding authority shall make direct payment to the subcontractor of the balance due under the subcontract including any amount due for extra labor and materials furnished to the general contractor, less any amount (i) retained by the awarding authority as the estimated cost of completing the incomplete or unsatisfactory items of work, (ii) specified in any court proceedings barring such payment, or (iii) disputed by the general contractor in the sworn reply; provided, that the awarding authority shall not deduct from a direct payment any amount as provided in part (iii) if the reply is not sworn to, or for which the sworn reply does not contain the detailed breakdown required by subparagraph (d). The awarding authority shall make further direct payments to the subcontractor forthwith after the removal of the basis for deductions from direct payments made as provided in parts (i) and (ii) of this subparagraph. (f) The awarding authority shall forthwith deposit the amount deducted from a direct payment as provided in part (iii) of subparagraph (e) in an interest-bearing joint account in the names of the general contractor and the subcontractor in a bank in Massachusetts selected by the awarding authority or agreed upon by the general contractor and the subcontractor and shall notify the general contractor and the subcontractor of the date of

24 | P a g e

the deposit and the bank receiving the deposit. The bank shall pay the amount in the account, including accrued interest, as provided in an agreement between the general contractor and the subcontractor or as determined by decree of a court of competent jurisdiction. (g) All direct payments and all deductions from demands for direct payments deposited in an interest-bearing account or accounts in a bank pursuant to subparagraph (f) shall be made out of amounts payable to the general contractor at the time of receipt of a demand for direct payment from a subcontractor and out of amounts which later become payable to the general contractor and in the order of receipt of such demands from subcontractors. All direct payments shall discharge the obligation of the awarding authority to the general contractor to the extent of such payment. (h) The awarding authority shall deduct from payments to a general contractor amounts which, together with the deposits in interest-bearing accounts pursuant to subparagraph (f), are sufficient to satisfy all unpaid balances of demands for direct payment received from subcontractors. All such amounts shall be earmarked for such direct payments, and the subcontractors shall have a right in such deductions prior to any claims against such amounts by creditors of the general contractor. (i) If the subcontractor does not receive payment as provided in subparagraph (a) or if the general contractor does not submit a periodic estimate for the value of the labor or materials performed or furnished by the subcontractor and the subcontractor does not receive payment for same when due less the deductions provided for in subparagraph (a), the subcontractor may demand direct payment by following the procedure in subparagraph (d) and the general contractor may file a sworn reply as provided in that same subparagraph. A demand made after the first day of the month following that for which the subcontractor performed or furnished the labor and materials for which the subcontractor seeks payment shall be valid even if delivered or mailed prior to the time payment was due on a periodic estimate from the general contractor. Thereafter the awarding authority shall proceed as provided in subparagraph (e), (f), (g) and (h).

7.2 The Owner has the right to request written evidence from the Contractor that the Contractor has properly paid Subcontractors and material and equipment suppliers amounts paid by the Owner to the Contractor for subcontracted Work. If the Contractor fails to furnish such evidence within seven days, the Owner shall have the right to contact Subcontractors to ascertain whether they have been properly paid. Neither the Owner nor Designer shall have an obligation to pay or to see to the payment of money to a Subcontractor, except as may otherwise be required by law. ARTICLE 8: DIFFERING SITE CONDITIONS; CONTRACT CLAIMS AND DISPUTES 8.1 As required by M.G.L. c. 30, Section 39N, the parties hereby agree:

If, during the progress of the work, the contractor or the awarding authority discovers that the actual subsurface or latent physical conditions encountered at the site differ substantially or materially from those shown on the plans or indicated in the contract

25 | P a g e

documents either the contractor or the contracting authority may request an equitable adjustment in the contract price of the contract applying to work affected by the differing site conditions. A request for such an adjustment shall be in writing and shall be delivered by the party making such claim to the other party as soon as possible after such conditions are discovered. Upon receipt of such a claim from a contractor, or upon its own initiative, the contracting authority shall make an investigation of such physical conditions, and, if they differ substantially or materially from those shown on the plans or indicated in the contract documents or from those ordinarily encountered and generally recognized as inherent in work of the character provided for in the plans and contract documents and are of such a nature as to cause an increase or decrease in the cost of performance of the work or a change in the construction methods required for the performance of the work which results in an increase or decrease in the cost of the work, the contracting authority shall make an equitable adjustment in the contract price and the contract shall be modified in writing accordingly.

8.2 CLAIMS AND DISPUTES 8.2.1 Notice of Claims. Claims against the Owner must be initiated within seven (7) days after occurrence of the event giving rise to such Claim or within seven (7) days after the Contractor first recognizes the condition giving rise to the Claim, whichever is later. Claims must be initiated by written notice to the Designer and the other party. 8.2.1.1 The Contractor’s failure to provide written notice in strict accordance with this paragraph will result in the Contractor’s having waived its Claim. Written notice submitted by the Contractor must include pricing of the Claim. 8.2.1.2 The Contractor shall furnish the Designer with such additional documentation as the Designer may request to evaluate the Claim. 8.2.2 Claims shall be referred to the Initial Decision Maker for initial decision. The Designer will serve as the Initial Decision Maker, unless otherwise indicated in the Contract Documents. An initial decision shall be required as a condition precedent to mediation of any Claim arising prior to the date final payment is due, unless 30 days have passed after the Claim has been referred to the Initial Decision Maker with no decision having been rendered. 8.2.2.1 The Initial Decision Maker will review Claims and within ten days of the receipt of a Claim take one or more of the following actions: (1) request additional supporting data from the claimant or a response with supporting data from the other party, (2) reject the Claim in whole or in part, (3) approve the Claim, (4) suggest a compromise, or (5) advise the parties that the Initial Decision Maker is unable to resolve the Claim if the Initial Decision Maker lacks sufficient information to evaluate the merits of the Claim or if the Initial Decision Maker concludes that, in the Initial Decision Maker’s sole discretion, it would be inappropriate for the Initial Decision Maker to resolve the Claim. 8.2.2.1.1 If the Initial Decision Maker requests a party to provide a response to a Claim or to furnish additional supporting data, such party shall respond, within ten days after receipt of

26 | P a g e

such request, and shall either (1) provide a response on the requested supporting data, (2) advise the Initial Decision Maker when the response or supporting data will be furnished or (3) advise the Initial Decision Maker that no supporting data will be furnished. Upon receipt of the response or supporting data, if any, the Initial Decision Maker will either reject or approve the Claim in whole or in part. 8.2.2.2 The Initial Decision Maker will render an initial decision approving or rejecting the Claim, or indicating that the Initial Decision Maker is unable to resolve the Claim. This initial decision shall (1) be in writing; (2) state the reasons therefor; and (3) notify the parties and the Designer, if the Designer is not serving as the Initial Decision Maker, of any change in the Contract Sum or Contract Time or both. The initial decision shall be final and binding on the parties but subject to mediation and/or litigation of the claim as provided herein. 8.2.3 Regardless of the disposition or status of a Claim, (except as otherwise agreed in writing or as provided elsewhere in the Contract Documents), the Contractor shall proceed diligently with performance of the Contract. The Designer will prepare Change Orders and issue Certificates for Payment in accordance with the decisions of the Initial Decision Maker. 8.2.4 Claims for Additional Cost. If the Contractor wishes to make a Claim for an increase in the Contract Sum, written notice as provided herein shall be given before proceeding to execute the Work. Prior notice is not required for Claims relating to an emergency endangering life or property. 8.2.4.1 Contractor hereby acknowledges that the Owner has the contractual right to delay the Work. Such right may not be exercised unreasonably. In addition, Contractor shall not be entitled to additional compensation as a result of delay, even if caused by the Owner or those for whom the Owner is responsible. The Contractor’s sole remedy for any delay is an extension of time, notwithstanding the above. Furthermore, the Contractor acknowledges that the Construction Schedule reflects the Contractor’s schedule expectations, based upon the Contract Documents, tests, surveys or plans heretofore submitted to the Contractor and Contractor’s visual inspection of the Project Site. The Contractor hereby agrees that is has taken these factors into account and the Contractor shall have no entitlement to an increase in the Contract Sum or any other additional costs, expenses or damages of whatsoever nature as they may relate to or otherwise arise from any delay, impact, or acceleration, except as and to the extent expressly provided under M.G.L. c.30, § 39O. The Contractor acknowledges that the Contractor’s sole remedy for any such delay and/or suspension will be an extension of time provided the Contractor complies with notice requirements contained in Section 8.2.1. 8.2.5 Claims for Additional Time. If the Contractor wishes to make a Claim for an increase in the Contract Time, written notice as provided herein shall be given. In the case of a continuing delay, only one Claim is necessary. 8.2.5.1 No increase in the Contract Time will be allowed for Work that is delayed as a result of the Contractor’s failure to timely submit, revise or resubmit shop drawings, product data, and/or samples.

27 | P a g e

8.2.5.2 No extension of time shall be granted because of seasonal, normal or abnormal variations in temperature, humidity, or precipitation, which conditions shall be wholly at the risk of the Contractor, whether occurring within the time originally scheduled for completion or within the period of any extension granted. Any additional cost of operations or conditions resulting therefrom shall be the responsibility of the Contractor. 8.2.5.3 The Owner shall not extend the Contract Time due to a delay until all Contract Float is used. 8.2.5.4 The Contractor shall have the burden of demonstrating the effect of the claimed delay on the Contract Time and shall furnish the Designer with such documentation relating to the claim as the Designer may reasonably require. The Progress schedule in the format required by the Contract Documents shall be used for determining the Contractor’s Rights to an extension of time under Section 9.2. The Designer will not be obligated to grant an extension of time unless the Contractor can demonstrate that the schedule has been negatively affected for reasons allowable under Section 9.3. If requested to do so by the Designer, the Contractor shall furnish additional hard copy print-outs of the revised Schedules and charts reflecting the actual or estimated time changes resulting from Change Orders or other events or actions which are the basis for the Claim for Additional Time. 8.2.6 The Contractor waives Claims against the Owner for consequential damages arising out of or relating to this Contract. This waiver includes damages incurred by the Contractor for principal office expenses including the compensation of personnel stationed there, for losses of financing, business and reputation, and for loss of profit except anticipated profit arising directly from the Work. This waiver is applicable, without limitation, to all consequential damages due to either party’s termination in accordance with the Contract Documents. 8.2.7 Claims, disputes or other matters in question between the parties to this Contract Agreement arising out of or relating to this Contract Agreement or breach thereof shall be subject to and decided by the Superior Court of Massachusetts in Middlesex County, if jurisdiction exists, and if jurisdiction does not exist in the Superior Court, said action shall be brought in the Woburn District Court of Massachusetts. A claim, dispute or other matter may be submitted to mediation, in accordance with the provisions of the American Arbitration Association, at the sole discretion of the Owner. 8.2.7.1 In the event that the Owner elects to demand mediation to settle any claim, dispute or matter in question, the parties shall share the mediator’s fee and any filing fees equally. The mediation shall be held in the place where the Project is located, unless another location is mutually agreed upon. Agreements reached in mediation shall be enforceable as settlement agreements in any court having jurisdiction thereof. 8.2.8 In the event of a Claim against the Contractor, the Owner may, but is not obligated to, notify the surety, if any, of the nature and amount of the Claim. If the Claim relates to a possibility of a Contractor’s default, the Owner may, but is not obligated to, notify the surety and request the surety’s assistance in resolving the controversy.

ARTICLE 9: PROGRESS OF WORK, SUBSTANTIAL COMPLETION, FINAL COMPLETION 9.1 Time limits stated in the Contract Documents are of the essence. The Contractor and its Subcontractors shall perform and coordinate all Work without delay. By executing the Agreement the Contractor confirms it has reviewed the Contract Documents and that the Contract Time is a reasonable period for performing the Work. The Contractor shall proceed expeditiously with adequate forces and shall achieve Substantial Completion within the Contract Time. 9.2 The term “Substantial Completion” as used in this Contract shall mean the point at which, as certified in writing by the Designer, the Designer has determined that the Project is at a level of completion in strict compliance with this Contract such that the Owner or its designee can enjoy beneficial use and can use or operate it in all respects for its intended purpose and only minor items which can be corrected or completed without any material interference with the Owner’s use of the Work remain to be corrected or completed. Partial use of the Project shall not result in the Project being deemed substantially complete, and such partial use shall not be evidence of substantial completion. 9.2.1 The Contractor shall submit, prior to requesting substantial completion, written certification that: (a) Equipment and systems have been tested in the presence of the Owner’s Representative and are operational; (b) Owner’s designated staff have been instructed on all equipment and systems and an Owner signed receipt has been furnished to the Designer; (c) Operational and Maintenance Manuals and record drawings have been submitted to and reviewed by the Designer and have been delivered to the Owner with required corrections. Submit copies of receipts signed by Owner’s representative; (d) Owner has received the specified guarantees and spare parts and the Owner has signed a receipt for same; and (e) Project has been completed and is ready for final inspection and an appropriate Certificate of Occupancy has been issued. 9.2.1.2 The Contractor shall also submit the following: (a) Contractor’s Affidavit of Payments for Debts and Claims; (b) Contractor’s Affidavit of Release of Liens; (c) Consent of Surety to Final Payment; and (d) Maintenance Guarantee. 9.2.2 The Contractor shall obtain and deliver promptly to the Designer any Occupancy Permit and any certificates of final inspection of any part of the Contractor’s Work and operating permits for any mechanical apparatus, such as elevators, escalators, boilers, and air compressors, which may be required by law to permit full use and occupancy of the premises by the Owner. Receipt of such permits or certificates by the Designer shall be a condition precedent to determining that the Work is Substantially Complete. 9.2.3 Punch List. When the Contractor considers that the Work, or a portion thereof which the Owner agrees to accept separately, is substantially complete, the Contractor shall prepare and submit to the Designer a comprehensive list, organized by room and trade, of items to be completed or corrected prior to final payment. Failure to include an item on such list does not alter the responsibility of the Contractor to complete all Work in accordance with the Contract

29 | P a g e

Documents. The punch list is to be complied with and in a process of active completion at the time of Substantial Completion, prior to the de-mobilization of major subcontractors. 9.2.3.1 Upon receipt of the Contractor’s list, the Designer and Owner will make an inspection to determine whether the Work or designated portion thereof is substantially complete. If the Designer’s inspection discloses any item, whether or not included on the Contractor’s list, which is not sufficiently complete in accordance with the Contract Documents so that the Owner can occupy or utilize the Work or designated portion thereof for its intended use, the Contractor shall, before issuance of the Certificate of Substantial Completion, complete or correct such item upon notification by the Designer. In such case, the Contractor shall then submit a request for another inspection by the Designer to determine Substantial Completion. 9.2.4 When the Work or designated portion thereof is substantially complete (in accordance with this Section 9.2), the Owner, with the advice and recommendation of the Designer, will determine the date of Substantial Completion, and the Designer will prepare a Certificate of Substantial Completion reflecting such date of Substantial Completion that shall establish the responsibilities of the Owner and Contractor for security, maintenance, heat, utilities, damage to the Work and insurance, and shall fix the time within which the Contractor shall finish all items on the list accompanying the Certificate. 9.2.4.1 The Certificate of Substantial Completion shall be submitted to the Owner and Contractor for their written acceptance of responsibilities assigned to them in such Certificate. Upon such acceptance and consent of surety, if any, the Owner shall make payment of retainage applying to such Work or designated portion thereof. Such payment shall be adjusted for Work that is incomplete or not in accordance with the requirements of the Contract Documents. 9.3 Partial Occupancy or Use. The Owner may occupy or use any completed or partially completed portion of the Work at any stage when such portion is designated by separate agreement with the Contractor. Such partial occupancy or use may commence whether or not the portion is substantially complete, provided the Owner and Contractor have accepted in writing the responsibilities assigned to each of them for payments, retainage, if any, security, maintenance, heat, utilities, damage to the Work and insurance, and have agreed in writing concerning the period for correction of the Work and commencement of warranties required by the Contract Documents. When the Contractor considers a portion substantially complete, the Contractor shall prepare and submit a list to the Designer as provided under Section 9.2. Consent of the Contractor to partial occupancy or use shall not be unreasonably withheld. The stage of the progress of the Work shall be determined by written agreement between the Owner and Contractor or, if no agreement is reached, by decision of the Designer. 9.3.1 Immediately prior to such partial occupancy or use, the Owner, Contractor and Designer shall jointly inspect the area to be occupied or portion of the Work to be used in order to determine and record the condition of the Work. 9.3.2 Unless otherwise agreed upon, partial occupancy or use of a portion or portions of the Work shall not constitute acceptance of Work not complying with the requirements of the Contract Documents.

30 | P a g e

9.4 Final Completion and Payment. Upon receipt of the Contractor’s written notice that the Work is ready for final inspection and acceptance and upon receipt of a final Application for Payment, the Designer and Owner will promptly make such inspection and, when the Owner, after consultation with the Designer, finds the Work acceptable under the Contract Documents and the Contract fully performed, will request the Designer to promptly issue a final Recommendation for Payment stating that to the best of the Designer’s knowledge, information and belief, and on the basis of the Designer’s on-site visits and inspections, the Work has been completed in accordance with terms and conditions of the Contract Documents, and that the entire balance found to be due the Contractor and noted in the final Certificate is due and payable. 9.4.1 Contractor shall submit, prior to requesting final inspection, written certification that: (a) Work has been completed in accordance with Contract Documents; and (b) Project has been inspected for compliance with Contract Documents. If the Designer or Owner does not consider the work finally complete, the Contractor will be notified, in writing, with the reasons stated. The Contractor will take immediate steps to correct the stated deficiencies and then submit a second written certification to the Designer and Owner. 9.4.2 Warranties required by the Contract Documents shall commence on the date of Final Completion of the Work or designated portion thereof unless otherwise provided in the Certificate of Substantial Completion. 9.4.3 Reinspection Costs. Should the Designer be required to reinspect the work because of failure of the Contractor to comply with the certification listed in 9.4.1, the Designer will bill the Owner for all related cost incurred, such cost will be deducted from the Contractor’s payment. 9.4.4 Neither final payment nor any remaining retained percentage shall become due until the Contractor submits to the Designer (1) an affidavit that payrolls, bills for materials and equipment, and other indebtedness connected with the Work for which the Owner or the Owner’s property might be responsible or encumbered (less amounts withheld by Owner) have been paid or otherwise satisfied, (2) a certificate evidencing that insurance required by the Contract Documents to remain in force after final payment is currently in effect and will not be canceled or allowed to expire until at least 30 days’ prior written notice has been given to the Owner, (3) a written statement that the Contractor knows of no substantial reason that the insurance will not be renewable to cover the period required by the Contract Documents, (4) consent of surety, if any, to final payment and (5), if required by the Owner, other data establishing payment or satisfaction of obligations, such as receipts, releases and waivers of liens, claims, security interests or encumbrances arising out of the Contract, to the extent and in such form as may be designated by the Owner. If a Subcontractor refuses to furnish a release or waiver required by the Owner, the Contractor may furnish a bond satisfactory to the Owner to indemnify the Owner against such lien. 9.4.5 Acceptance of final payment by the Contractor, a Subcontractor or material supplier shall constitute a waiver of claims by that payee.

31 | P a g e

9.4.6 One-Year Warranty Repair List and Inspection. Approximately thirty (30) days prior to the expiration of the comprehensive one-year warranty period, the Contractor shall schedule an appointment with the Owner for a re-inspection of the Work with the Owner, and shall thereafter inspect the work at the time scheduled. Based on this inspection and on prior inspections, the Owner shall issue a “Warranty Repair List” of items to be corrected by the Contractor. The Contractor shall make the repairs and/or replacements listed within thirty (30) days of the issuance of the Warranty Repair List unless otherwise agreed by the Owner in writing. ARTICLE 10: CHANGES IN THE WORK 10.1 Upon the request of the Owner or the Designer, the Contractor shall, within 15 days (sooner if necessary to avoid delays in work) and without cost to the Owner, submit to the Designer, in such form as the Designer may require, an accurate written Change Order Proposal for the cost of any proposed extra work or change. The estimate shall indicate the quantity in unit cost of each item of materials, and the numbers of hours of work and an hourly rate for each class of labor, as well as the description in amounts of all other costs sought by the Contractor and chargeable under the terms of this article. Unit labor costs for the installation of each item of materials shall be shown if required by the Designer. The Contractor shall promptly revise and resubmit such estimate if the Designer determines that it is not in compliance with the requirements of this article, or that it contains errors of fact or determines that it is not in compliance with the requirements of this article, or that it contains errors of fact or mathematical errors. If required by the Designer in order to establish the exact cost of the new work added or of previously required work omitted, the Contractor shall obtain and furnish to the Designer bona fide proposals from subcontractors and suppliers for furnishing any labor and material included in such work. Such estimates shall be furnished promptly so as to occasion no delay in the work and be furnished at the Contractor’s expense. The Contractor shall state in the estimate any extension of time required for the completion of the work if the change or extra work is ordered. Percentages for overhead and profit included in the proposal shall be in accordance with Paragraph 10.2. 10.1.2 Change Order Proposals shall be complete and definitive, and the amount of the adjustment in the Contract Sum and the Contract Time, if any, shall be stated in the proposal for all Work affected by the proposed Change. Once a Change Order is executed, the Contractor shall be required to perform all of the Work required therein (including incidental work and changes to related Work which may be required to complete the Change Order) in accordance with the Contract Documents, for the amounts stated in the Change Order. 10.1.3 Contractor’s requests for changes or substitutions shall be subject to the same requirements as change initiated by the Designer or Owner. 10.2 Where the value of work performed directly by the Contractor under a Change Order or a Construction Change Directive is determined by either a lump sum proposal or by actual cost of work as it progresses, the Contractor will be allowed an additional amount of five percent (5%) of the total cost of material and labor, as combined overhead, superintendence, and profit. Cost of the work shall include the cost at prevailing rates for direct labor, material and use of equipment, plus the cost of workmen’s compensation insurance, liability insurance, federal social security and Massachusetts unemployment compensation. Mark-up for overhead,

32 | P a g e

superintendence, and profit shall include (and no additional payment shall be made for) general conditions, management, supervision, coordination, insurance, bonds, mobilization, record drawings, engineering/layout, small tools/computers, “tools of the trade,” transit staging/scaffolding, lifting, hoisting, dumpster, handling, clean-up, temporary weather protection, temporary heat and utilities, shipping/receiving, administration, accounting, punch list, O & M manuals, estimator time, schedule updating, safety protection, certified payrolls, street sweeping, police barricades, signs, construction fences, and the like. Surcharges for subcontracted work, where required or permitted, shall be as follows: (a) To the Subcontractor or Sub-subcontractor performing the work, five percent (5%) of the total cost of labor and materials; (b) To payments made to a Sub-subcontractor, the Subcontractor will be allowed an additional five percent (5%); (c) To the total payment made to the Subcontractor, the Contractor will be allowed an additional five percent (5%) to cover increased overhead and profit; (d) On any changes involving the Contractor, application of the percentage allowed for the Contractor’s overhead and profit; (e) No additional costs will be allowed of any lower tier of Subcontractors. 10.2.1 If deductions are ordered, the credit shall be computed as net cost. 10.2.2 The General Contractor shall not sublet any work under a Change Order or a Construction Change Directive unless work under the basic Contract of a similar type was previously subcontracted; and Subcontractors will not be allowed to further sublet any work under a Change Order unless the work under the basic Contract of a similar type was previously sublet by them, without the written approval and acceptance of the Owner. 10.2.3 All changes in the Work shall be in accordance with provisions of the M.G.L. c. 30, § 39I. 10.3 The Contractor agrees to perform all Work as directed by the Owner, and if the Owner determines that certain Work that the Contractor believes to be or to warrant a Change Order under this Article does not represent a change in the Work, the Contractor shall perform said Work. The Contractor shall be deemed to have concurred with the Owner’s determination as aforesaid unless the Contractor shall perform Work under protest in compliance with the following subsections 10.3.1 and 10.3.2, below. 10.3.1 If the Contractor claims compensation for a change in the Work that is not deemed by the Owner to be a change or to warrant additional compensation as claimed by the Contractor, the Contractor shall on or before the first working day following the commencement of any such work or the sustaining of any such damage submit to the Designerand the Owner a written statement of the nature of such work or claim. The Contractor shall not be entitled to additional compensation for any work performed or damage sustained for which written notice is not given within the time limit specified in the preceding sentence, even though similar in character to work or damage with respect to which notice is timely given. 10.3.2 On or before the second working day after the commencement of such work or the sustaining of such damage, and daily thereafter, the Contractor shall file to the extent possible with the Designer and the Owner itemized statements on forms reasonably acceptable to the Town of the details and costs of such work performed or damage sustained. If the Contractor shall fail to

33 | P a g e

make such statements to the extent possible, then the Contractor shall not be entitled to additional compensation for any such work or damages 10.4 CHANGE ORDERS 10.4.1 A Change Order is a written instrument prepared by the Designer and signed by the Owner, Contractor and Designer stating their agreement upon all of the following: (a) the change in the Work; (b) the amount of the adjustment, if any, in the Contract Sum; and (c) the extent of the adjustment, if any, in the Contract Time. 10.4.2 As provided in M.G.L., c. 30, § 39P, whenever the Town, awarding authority, engineer or architect is requested to make a decision on interpretation of the specifications, approval of equipment, material or any other approval, or progress of the work, he shall make that decision promptly and, in any event, no later than thirty days after the written submission for decision. However, if such decision requires extended investigation and study, the person making the decision shall, within thirty days after receipt of the submission, give the party making the decision written notice of the reasons why the decision cannot be made within the thirty day period and the date by which the decision will be made. 10.4.3 A Change Order signed by the Contractor indicates the Contractor’s agreement therewith, including any adjustment in the Contract Sum and Contract Time. 10.4.4 M.G.L. c. 44, Sec. 31 C provides that no change order that results in additional cost shall be deemed to have been given until the accountant or other officer of the Town having similar duties has certified thereon that an appropriation in the amount of such order is available therefore; but such certificate shall not be construed as an admission by the Town of its liability to pay for such work; rather, such certification shall bar any defense by the Town on the grounds of insufficient appropriation. 10.5 CONSTRUCTION CHANGE DIRECTIVES 10.5.1 A Construction Change Directive is a written order prepared by the Designer or the Owner and signed by the Owner and Designer, directing a change in the Work prior to agreement on adjustment, if any, in the Contract Sum or Contract Time, or both. The Owner may by Construction Change Directive, without invalidating the Contract, order changes in the Work within the general scope of the Contract consisting of additions, deletions or other revisions, the Contract Sum and Contract Time being adjusted accordingly. 10.5.2 A Construction Change Directive shall be used in the absence of total agreement on the terms of a Change Order. 10.5.3 If the Construction Change Directive provides for an adjustment to the Contract Sum, the adjustment shall be based on one of the following methods: (a) mutual acceptance of a lump sum properly itemized and supported by sufficient substantiating data to permit evaluation; (b) unit prices stated in the Contract Documents or subsequently agreed upon; (c) cost to be determined

34 | P a g e

in a manner agreed upon by the parties and, if required or permitted, an additional amount or surcharge as provided in Section 10.2; or (d) As provided in Section 10.7. 10.5.4 A Construction Change Directive signed by the Contractor indicates the Contractor’s agreement therewith, including adjustment in Contract Sum and Contract Time or the method for determining them. Such agreement shall be effective immediately and shall be recorded as a Change Order. 10.6 Upon receipt of a Construction Change Directive, the Contractor shall promptly proceed with the change in the Work involved and advise the Designer and Owner of the Contractor’s agreement or disagreement with the method, if any, provided in the Construction Change Directive for determining the proposed adjustment in the Contract Sum or Contract Time. 10.7 If the Contractor does not respond promptly or disagrees with the method for adjustment in the Contract Sum, the Owner, after obtaining the recommendation of the Designer shall determine the method and the adjustment on the basis of reasonable expenditures and savings of those performing the Work attributable to the change, including, in case of an increase in the Contract Sum, an amount for combined overhead, superintendence and profit as set forth in Section 10.2. In such case, and also under Section 10.5.3(d), the Contractor shall keep and present, in such form as the Designer may prescribe, an itemized accounting together with appropriate supporting data. Unless otherwise provided in the Contract Documents, costs for the purposes of this Section 10.7 shall be limited to the following: (a) costs of labor, including social security, old age and unemployment insurance, fringe benefits required by agreement or custom, and workers’ compensation insurance; (b) costs of materials, supplies and equipment, including cost of transportation, whether incorporated or consumed; and (c) rental costs of machinery and equipment, exclusive of hand tools, whether rented from the Contractor or others. 10.8 The amount of credit to be allowed by the Contractor to the Owner for a deletion or change that results in a net decrease in the Contract Sum shall be actual net cost as confirmed by the Designer and agreed by the Owner. When both additions and credits covering related Work or substitutions are involved in a change, the allowance for overhead and profit shall be figured on the basis of net increase, if any, with respect to that change 10.9 Pending final determination of the total cost of a Construction Change Directive to the Owner, the Contractor may request payment for Work completed under the Construction Change Directive in Applications for Payment. The Designer will make an interim determination for purposes of monthly certification for payment for those costs and certify for payment the amount that the Designer determines, in the Designer’s professional judgment, to be reasonably justified. The Designer’s interim determination of cost shall adjust the Contract Sum on the same basis as a Change Order, subject to the right of either party to disagree and assert a Claim in accordance with this Contract Agreement. 10.10 When the Owner and Contractor agree with a determination made by the Designer concerning the adjustments in the Contract Sum and Contract Time, or otherwise reach agreement upon the adjustments, such agreement shall be effective immediately and the

35 | P a g e

Designer will prepare a Change Order. Change Orders may be issued for all or any part of a Construction Change Directive. 10.11 Minor Changes in Work. The Designer has authority to order minor changes in the Work not involving adjustment in the Contract Sum or extension of the Contract Time and not inconsistent with the intent of the Contract Documents. Such changes will be effected by written order signed by the Designer and shall be binding on the Owner and Contractor. ARTICLE 11: NONPERFORMANCE 11.1 In the case of any default on the part of the Contractor with respect to any of the terms of this Agreement, the Town shall give written notice thereof, and if said default is not made good within such time as the Town shall specify in writing, the Town shall notify the Contractor in writing that there has been a breach of the Agreement and thereafter the Town shall have the right to secure the completion of the work remaining to be done on such terms and in such manner as the Town shall determine, and the Contractor shall pay for the completion of such work and reimburse the Town for all expenses incurred by reason of said breach. The Contractor in case of such breach shall be entitled to receive payment only for work completed satisfactorily prior to said breach, so long as the total paid hereunder does not exceed the Contract sum, and the amount of any balance due the Contractor shall be determined by the Town and certified to the Contractor. The Contractor shall reimburse the Town for the cost of additional services required by the Town in the case of a breach. 11.2 If the Contractor defaults or neglects to carry out the Work in accordance with the Contract Documents and fails within a ten-day period after receipt of written notice from the Owner to immediately correct such default or neglect with diligence and promptness, the Owner may, without prejudice to other remedies the Owner may have (including Termination in accordance with the Contract Documents), correct such deficiencies. In such case an appropriate Construction Change Directive shall be issued deducting from payments then or thereafter due the Contractor the reasonable cost of correcting such deficiencies, including Owner’s expenses and compensation for the Project Manager’s and Designer’s additional services made necessary by such default, neglect or failure. If payments then or thereafter due the Contractor are not sufficient to cover such amounts, the Contractor shall pay the difference to the Owner. In the event that the Contractor’s failure to prosecute the Work causes (in the opinion of the Owner), a risk of harm to the public, the Owner shall have the right to carry out the Work without notice at the Contractor’s cost and/or deduct such sums from monies due the Contractor. 11.3 If the Contractor fails to correct Work that is not in accordance with the requirements of the Contract Documents as required herein or fails to carry out Work in accordance with the Contract Documents, the Owner may in addition to any other remedy it may have herein, terminate in accordance with this Agreement or issue a written order to the Contractor to stop the Work, or any portion thereof, until the cause for such order has been eliminated; however, the right of the Owner to stop the Work shall not give rise to a duty on the part of the Owner to exercise this right for the benefit of the Contractor or any other person or entity. ARTICLE 12: TERMINATION

36 | P a g e

12.1 The Owner may, at any time, terminate the Contract for the Owner’s convenience and without cause. Further, if the Contractor is adjudged a bankrupt, or if the Contractor makes a general assignment for the benefit of the Contractor’s creditors, or if a receiver is appointed on account of the Contractor’s insolvency, or if the Contractor consistently or repeatedly refuses or fails, excepting cases of which extension of time is appropriated, to supply enough properly skilled workmen or proper materials, or if the Contractor fails to make prompt payment to the Subcontractors of for materials or labor, or persistently disregards law, ordinances, rules, regulations, or orders of any public authority having jurisdiction or disregards an instruction, order or decision of the Designer, or otherwise is guilty of a substantial violation of any provision of the contract, then the Contractor shall be in default, and the Owner may, without prejudice to any other right or remedy and upon written notice to the Contractor, take possession of all materials, tools, appliances, equipment, construction equipment, and machinery and vehicles, offices and other facilities on the project site and all material intended for the work, wherever stored, and seven days after such notice may terminate the employment of the contract, accept assignment of any or all Subcontractor’s contracts, and furnish the work by whatever method the Owner may deem expedient. The Owner shall be entitled to collect from the Contractor all direct, indirect, consequential damages suffered by the Owner of behalf of the Contractor’s defaults, including without limitations additional services and expenses of the Designer and/or the Designer’s consultants made necessary thereby. The Owner shall be entitled to hold all amounts due to Contractor at the date of termination until all of the Owner’s damages have been established, and to apply such amounts to such damages. 12.1.2 The Owner shall incur no liability by reason of such termination. 12.2 Upon receipt of written notice from the Owner of termination for the Owner’s convenience, the Contractor shall: (a) cease operations as directed by the Owner in the notice; (b) take actions necessary, or that the Owner may direct, for the protection and preservation of the Work; and (c) except for Work directed to be performed prior to the effective date of termination stated in the notice, terminate all existing subcontracts and purchase orders and enter into no further subcontracts and purchase orders. 12.3 In case of termination for the Owner’s convenience, the Contractor shall be entitled to receive payment only for work executed and to the extent approved and to the extent recommended by the Designer and approved by the Owner. Contractor waives all claims for damages, including loss of anticipated overhead recovery or profits, on account of such termination. The payments provided for herein shall be Contractor’s sole rights and remedy in the event of termination for convenience or for cause. Provisions of the Contract Documents that by their nature survive final acceptance of the Work shall remain in full force and effect after such termination to the extent therein provided. 12.4 The Contractor shall not be relieved of liability to the Owner by virtue of any termination of this Contract, and any claim for damages against the Contractor relating to the Contractor’s performance under this Contract shall survive any termination hereunder. ARTICLE 13: SUBCONTRACTING

37 | P a g e

13.1 Unless otherwise stated in the Contract Documents or the bidding requirements, the Contractor, as soon as practicable after award of the Contract, shall furnish in writing to the Owner and the Designer the names of persons or entities (including those who are to furnish materials or equipment fabricated to a special design) proposed for each principal portion of the Work. The Designer may reply within 14 days to the Contractor in writing stating (1) whether the Owner or the Designer has reasonable objection to any such proposed person or entity or (2) that the Designer requires additional time for review. Failure of the Owner or Designer to reply within the 14-day period shall constitute notice of no reasonable objection. 13.2 The Contractor shall not contract with a proposed person or entity to whom the Owner or Designer has made reasonable and timely objection. The Contractor shall not be required to contract with anyone to whom the Contractor has made reasonable objection. 13.3 If the Owner, or Designer has reasonable objection to a person or entity proposed by the Contractor, the Contractor shall propose another to whom the Owner or Designer has no reasonable objection. If the proposed but rejected Subcontractor was reasonably capable of performing the Work, the Contract Sum and Contract Time shall be increased or decreased by the difference, if any, occasioned by such change, and an appropriate Change Order shall be issued before commencement of the substitute Subcontractor’s Work. However, no increase in the Contract Sum or Contract Time shall be allowed for such change unless the Contractor has acted promptly and responsively in submitting names as required. 13.4 The Contractor shall not substitute a Subcontractor, person or entity previously selected if the Owner, or Designer makes reasonable objection to such substitution. 13.5 The provisions of Sections 12.1 through 12.4 shall not apply to the designated filed Sub-Bidders under this Contract. Such Subcontracts shall be in accordance with Chapter 149, Sections 44A through 44I inclusive of the General Laws of Massachusetts as amended. 13.6 The subcontract for Filed Sub-Bidders shall be the FORM FOR SUBCONTRACT included in the Contract Documents or, if not published with these specifications, it shall be the form and language established by Chapter 149 of the Massachusetts General Laws. 13.7 By appropriate agreement, written where legally required for validity, the Contractor shall require each Subcontractor, to the extent of the Work to be performed by the Subcontractor, to be bound to the Contractor by terms of the Contract Documents, and to assume toward the Contractor all the obligations and responsibilities, including the responsibility for safety of the Subcontractor’s Work, which the Contractor, by these Documents, assumes toward the Owner and Designer. Each subcontract agreement shall preserve and protect the rights of the Owner and Designer under the Contract Documents with respect to the Work to be performed by the Subcontractor so that subcontracting thereof will not prejudice such rights, and shall allow to the Subcontractor, unless specifically provided otherwise in the subcontract agreement, the benefit of all rights, remedies and redress against the Contractor that the Contractor, by the Contract Documents, has against the Owner. Where appropriate, the Contractor shall require each Subcontractor to enter into similar agreements with Sub-subcontractors. The Contractor shall make available to each proposed Subcontractor, prior to the execution of the subcontract

38 | P a g e

agreement, copies of the Contract Documents to which the Subcontractor will be bound, and, upon written request of the Subcontractor, identify to the Subcontractor terms and conditions of the proposed subcontract agreement that may be at variance with the Contract Documents.

The Contractor shall cooperate fully with other contractors, afford other contractors reasonable opportunity for the introduction and storage of their material and the execution of their work, and carefully fit its own work to that of other contracts as may be directed by the Contracting Officer. The Contractor shall not commit or permit any acts which will interfere with the performance of work by any other contractor. 14.1.2 If such separate Contractor sues or initiates an arbitration proceeding against the Owner on account of any damage alleged to have been caused by the Contractor, the Owner shall notify the Contractor, who shall defend such proceedings at the Owner’s expense, and if any judgment or award against the Owner arises therefrom the Contractor shall pay or satisfy it and shall reimburse the Owner for all attorney’s fees and court or arbitration costs which the Owner has incurred. 14.1.3 The Owner reserves the right to access any part of the Project at any time to install other Work, either with its own forces or with separate contractors hired by the Owner.

The Contractor shall permit the Owner to place and install furniture, equipment and other acceptance of the Work or any portion thereof. 14.1.4 The Contractor shall afford the Owner and separate contractors reasonable opportunity for introduction and storage of their materials and equipment and performance of their activities, and shall connect and coordinate the Contractor’s construction and operations with theirs as required by the Contract Documents. 14.2 If part of the Contractor’s Work depends for proper execution or results upon construction or operations by the Owner or a separate contractor, the Contractor shall, prior to proceeding with that portion of the Work, promptly report to the Designer apparent discrepancies or defects in such other construction that would render it unsuitable for such proper execution and results. Failure of the Contractor so to report shall constitute an acknowledgment that the Owner’s or separate contractor’s completed or partially completed construction is fit and proper to receive the Contractor’s Work, except as to defects not then reasonably discoverable. 14.3 The Contractor shall reimburse the Owner for costs the Owner incurs that are payable to a separate contractor because of the Contractor’s delays, improperly timed activities or defective construction. 14.4 The Contractor shall promptly remedy damage the Contractor causes to completed or partially completed construction or to property of the Owner or separate contractors. 15.

Information about Prevailing Wage Schedules for Awarding Authorities and Contractors

• This wage schedule applies only to the specific project referenced at the top of this page and uniquely identified by the

“Wage Request Number” on all pages of this schedule.

• An Awarding Authority must request an updated wage schedule from the Department of Labor Standards (“DLS”) if it has

not opened bids or selected a contractor within 90 days of the date of issuance of the wage schedule. For CM AT RISK

projects (bid pursuant to G.L. c.149A), the earlier of: (a) the execution date of the GMP Amendment, or (b) the bid for the

first construction scope of work must be within 90-days of the wage schedule issuance date.

• The wage schedule shall be incorporated in any advertisement or call for bids for the project as required by M.G.L. c. 149,

§ 27. The wage schedule shall be made a part of the contract awarded for the project. The wage schedule must be posted in a

conspicuous place at the work site for the life of the project in accordance with M.G.L. c. 149 § 27. The wages listed on the

wage schedule must be paid to employees performing construction work on the project whether they are employed by the

prime contractor, a filed sub-bidder, or any sub-contractor.

• All apprentices working on the project are required to be registered with the Massachusetts Department of Labor

Standards, Division of Apprentice Standards (DLS/DAS). Apprentice must keep his/her apprentice identification card on

his/her person during all work hours on the project. An apprentice registered with DAS may be paid the lower apprentice

wage rate at the applicable step as provided on the prevailing wage schedule. Any apprentice not registered with DLS/DAS

regardless of whether or not they are registered with any other federal, state, local, or private agency must be paid the

journeyworker's rate for the trade.

• The wage rates will remain in effect for the duration of the project, except in the case of multi-year public construction

projects. For construction projects lasting longer than one year, awarding authorities must request an updated wage schedule.

Awarding authorities are required to request these updates no later than two weeks before the anniversary of the date the

contract was executed by the awarding authority and the general contractor. For multi-year CM AT RISK projects, awarding

authority must request an annual update no later than two weeks before the anniversary date, determined as the earlier of: (a)

the execution date of the GMP Amendment, or (b) the execution date of the first amendment to permit procurement of

construction services. Contractors are required to obtain the wage schedules from awarding authorities, and to pay no less than

these rates to covered workers. The annual update requirement is not applicable to 27F “rental of equipment” contracts.

• Every contractor or subcontractor which performs construction work on the project is required to submit weekly payroll

reports and a Statement of Compliance directly to the awarding authority by mail or email and keep them on file for three

years. Each weekly payroll report must contain: the employee’s name, address, occupational classification, hours worked, and

wages paid. Do not submit weekly payroll reports to DLS. A sample of a payroll reporting form may be obtained at

• Contractors with questions about the wage rates or classifications included on the wage schedule have an affirmative

obligation to inquire with DLS at (617) 626-6953.

• Employees not receiving the prevailing wage rate set forth on the wage schedule may report the violation to the Fair Labor

Division of the office of the Attorney General at (617) 727-3465.

• Failure of a contractor or subcontractor to pay the prevailing wage rates listed on the wage schedule to all employees who

perform construction work on the project is a violation of the law and subjects the contractor or subcontractor to civil and

criminal penalties.
