ARTICLE X COMPLIANCE WITH LAWS

The Contractor shall keep himself fully informed of all existing and future State and National Laws and municipal ordinances and regulations in any manner affecting those engaged or employed in the work, or the materials used in the work, or in any way affecting the conduct of the work, and of all such orders and decrees of bodies or tribunals having any jurisdiction or authority over the same.

ARTICLE XV TIME OF COMMENCEMENT

Except as herein provided, the Contractor shall commence work at such points as the Engineer may approve, within ten (10) days after the execution of the contract by the Awarding Authority.

ARTICLE XVI DELAY BY AWARDING AUTHORITY

The Awarding Authority may delay the beginning of the work or any part thereof, if the necessary lands or rights-of-way for such work shall not have been obtained or if materials or equipment to be furnished by the Awarding Authority are not delivered. The Contractor shall not have claim for damages on account of such delay but shall be entitled to so much additional time wherein to perform and complete this contract on his part, as the Engineer shall certify in writing to be just.

ARTICLE XVII TIME OF COMPLETION

The rate of progress shall be such that the work shall be performed in accordance with the terms of this contract to substantial completion within 365 calendar days after the date of execution of the contract stipulated in the proposal, unless and, except as any part may be delayed under the provisions of this contract. It is agreed that the rate of progress herein required has been purposely made low enough to allow for the ordinary delays incident to construction work of this character. No extension of time will be made for ordinary delays, inclement weather and accidents, and the occurrence of such will not relieve the Contractor from the necessity of maintaining this rate of progress. If delays are caused by acts of nature, acts of Government or State, strikes, extra work, floods, or there are contingencies clearly beyond the control or responsibilities of the Contractor, the Contractor shall be entitled to so much additional time wherein to perform and complete this contract on his part as the Awarding Authority may grant, after certification thereto by the Engineer. The time in which this contract is to be performed and completed is of the essence of this Agreement.

ARTICLE XVIII LIQUIDATED DAMAGES

In case the Contractor fails satisfactorily to complete the entire work contemplated and provided for under this contract on or before the date of completion determined as described above, the Awarding Authority shall deduct from the payments due the Contractor each month the sum of Two Thousand dollars {$2,000.00) plus engineering charges for each calendar day {Sundays and legal holidays excluded) of delay, which sum is agreed upon not as a penalty but as fixed and liquidated damages for each day of such delay, to be paid in full and subject to no deduction. If the payments due the Contractor are less than the amount of such liquidated damages, said damages shall be deducted from any other monies due or to become due the Contractor, and in case such damages shall exceed the amount of all monies due or to become due the Contractor, then the Contractor or his surety shall pay the balance to the Awarding Authority. In addition to the above, if the contract is not completed within the time specified, and no extension of time is authorized by the Awarding Authority, the Contractor shall indemnify the Awarding Authority for costs to the Awarding Authority of Inspection of the work during any such extension period.

ARTICLE XIX EMPLOY COMPETENT WORKERS

The Contractor shall employ only competent persons to do the work, and whenever the Awarding Authority or Engineer shall notify the Contractor in writing that any worker on the work is, in his opinion, incompetent, unfaithful, disorderly, or otherwise unsatisfactory, such worker shall be discharged from the work and shall not again be employed on it, except with the consent of the Awarding Authority or Engineer.

ARTICLE XX EMPLOY SUFFICIENT LABOR AND EQUIPMENT

If, in the opinion of the Engineer, the Contractor is not employing sufficient labor and equipment to complete this contract within the time specified, said Contractor is to employ such additional labor and equipment as may be necessary to enable said work to properly progress.

ARTICLE XXI INTOXICATING LIQUORS The Contractor shall not sell and shall neither permit nor suffer the introduction or use of intoxicating liquors upon or about the work embraced in this contract.

ARTICLE XXII ACCESS TO WORK

The Awarding Authority and the Engineer, and their agents and employees, may, for purposes already specified and for any other purpose, enter upon the work and the premises used by the Contractor, and the Contractor shall provide safe and proper facilities therefore.

ARTICLE XXIII EXAMINATION OF WORK

The Engineer shall be furnished with every reasonable facility for ascertaining that the work is in accordance with the requirements and intention of this contract, even to the extent of uncovering or taking down portions of finished work. Should the work thus exposed or examined prove satisfactory, the uncovering or taking down and the restoring and replacing of the material and rebuilding the part shall be considered as extra work, unless the original work was done in the absence of the Engineer or his inspector without his written authorization, in which case the cost shall be borne by the Contractor. Should the work exposed or examined prove unsatisfactory, the uncovering, taking down, replacing, and making good shall be at the expense of the Contractor.

ARTICLE XXIV DEFECTIVE WORK

The inspection of the work shall not relieve the Contractor of any of his obligations to fulfill his contract as herein prescribed, and defective work shall be made good and unsuitable material shall be rejected, notwithstanding that such work and materials have been previously overlooked by the Engineer and accepted or estimated for payment. If the work or any part thereof shall be found defective at any time before the final acceptance of the whole work, the Contractor shall forthwith make good such defect, in a manner satisfactory to the Engineer, and if any material brought upon the ground for use in the work, or selected for the same, shall be condemned by the Engineer as unsuitable or not in conformity with the specifications, the Contractor shall forthwith remove such materials from the vicinity of the work, and any material furnished by the Awarding Authority which shall be damaged or rendered defective by the handling or improper installation by the Contractor, his agent, or employees, shall be made good and replaced at the Contractor's own expense.

ARTICLE XXV PROTECTION AGAINST WATER AND STORM

The Contractor shall take all precaution to prevent damage to the work by storms or by water entering the site of the work directly or through the ground. In case of damage by storm or water, the Contractor shall make repairs or replacements or rebuild such parts of the work as the Engineer may require in order that the finished work may be completed as required by the drawings and specifications. The Engineer may prohibit the carrying out of any work at any time when, in his judgment, the conditions are not suitable or the proper precautions are not being taken, whatever the weather may be, in any season.

ARTICLE XXVI MISTAKES OF CONTRACTOR

The Contractor shall pay to the Awarding Authority all expenses, losses, and damages as determined by the Engineer, incurred in consequence of any defect, omission, or mistake of the Contractor, or his employees, or the making good thereof.

ARTICLE XXVII RIGHT TO MATERIALS

Nothing in this contract shall be construed as vesting in the Contractor any right of property in the materials used after they have been attached or affixed to the work or the soil, but all such materials shall, upon being so attached or affixed, become the property of the Awarding Authority.

ARTICLE XXVIII INTERPRETATION OF CONTRACT AS TO LIMITATIONS OF WORK

Should it be deemed necessary in the execution of the work, by reason of any condition or circumstances arising or discovered after the making of the contract, to make any minor variation desirable or necessary for the stability, safety, economy or betterment of the work, which variations increase or decrease the quantities of the work specified, or change the location thereof to an extent not unreasonably affecting the condition of the work, and further interpreted by the Engineer as involving no classes of work other than those called for by the contract, the Contractor shall, upon written order from the Engineer to that effect, make such minor variations. If such minor variations diminish the quantity of work to be done, no claim for damages or for anticipated profits on the work that may be dispensed with shall thereby accrue to the Contractor, and the value of the work dispensed with will not be included in any payments made to the Contractor. If such minor variations increase the amount of work, the value of such increase shall be determined and fixed by the Engineer in accordance with the quantity of such work actually done, and at the unit prices stipulated in the contract.

Such alterations or changes as are mentioned in this section shall not vitiate or annul the obligations of the contract or the agreement for the work.

Should the Contractor consider himself entitled to extra compensation on account of the before-mentioned alterations or changes, he shall notify the Awarding Authority by making his claim in writing to the Engineer before proceeding with the work in question.

Should the Contractor proceed with the said work in compliance with the order of the Engineer, it is to be construed as his acceptance of the order and of the stipulated compensation for the said work. Should, in the opinion of the Engineer, any contemplated change in the quantities of the work or alterations thereof, materially change the character of the work or any part thereof, or materially affect the compensation for some, then the work shall be classified as extra work.

ARTICLE XXIX EXTRA WORK

The Contractor shall do any work incidental to the proper completion of the contract not herein otherwise provided for when and as ordered in writing by the Engineer and approved by the Awarding Authority. The amount of compensation to be paid to the Contractor for any extra work, as so ordered, shall be determined as follows:

1 By such applicable unit prices, if any, as are set forth in the contract; or 2 If no such unit prices are so set forth, then by unit prices or by a lump sum mutually agreed by the Awarding Authority and the Contractor; or 3 If no such unit prices are so set forth and if the parties cannot agree upon unit prices or a lump sum then by the actual net cost in money to the Contractor as approved by the Engineer of the materials and of the wages of applied labor required for such extra work, plus such rental of plant and equipment (other than small tools) required and approved for such extra work, plus fifteen per cent (15%}. No extra work will be paid for unless specifically ordered as such by the Engineer in writing.

The Contractor shall, when requested by the Engineer so, furnish itemized statements of the cost of the work ordered and give the Engineer access to the accounts, bills, and vouchers relating thereto.

The Engineer shall include in the cost of extra work under (3) as stated above, the reasonable cost to the Contractor or all materials used, of all labor, common and skilled, of foreman, and the fair rental of all machinery used upon the extra work for the period of such use.

The fair rental of all machinery shall be based upon the most recent edition of "Compilation of Rental Rates for Construction Equipment," as published by the Associated Equipment Distributors or similar publication approved by the Engineer. Rental for machinery that was upon the work immediately before, or which shall be required by or used upon the work after the extra work is done, shall be based upon an appropriate fraction of the approved monthly rate schedule. If said work requires the use of machinery not upon the work site and not contemplated to be used upon the work, then the cost of transportation, not exceeding a distance of 100 miles, of such machinery to and from the work shall be added to the fair rental as accepted by the Engineer in writing prior to the rental of the machine.

The Engineer shall include in the cost of extra work the cost to the Contractor of additional premiums paid on the required insurance on account of such extra work, and the cost of Social Security or other direct assessment upon the Contractor's payroll by Federal or other properly authorized public agencies. The Engineer shall not include in the cost of extra work any cost or rental of small tools, buildings, or any portion of the time of the Contractor or his superintendent, or any allowance for use of capital or the premium on the bond as assessed upon the amount of extra work, these items being considered as being covered by the fifteen percent added to the reasonable cost.

ARTICLE XXX EXTENTSION OF TIME ON ACCOUNT OF EXTRA WORK

When extra work is ordered near the completion of the contract, or when extra work is ordered at any time during the progress of the work, which requires, in the opinion of the Engineer, an unavoidable increase of time for the completion of the contract, a suitable extension of the time of completion shall be made, only upon approval of the Awarding Authority.

ARTICLE XXXI CHANGES NOT TO AFFECT BOND

It is distinctly agreed and understood that any changes made in the drawings and specifications for this work (whether such changes increase or decrease the amount thereof) or any change in the manner or time of payments made by the Awarding Authority to the Contractor, shall in no way annul, release, or affect the liability and surety on the bond given by the Contractor.

ARTICLE XXXII CLAIMS FOR DAMAGES

If the Contractor claims compensation for any damages sustained by breach of contract or otherwise, be the same based on claims that are due and full credit has not been given the Contractor for work performed or material furnished in accordance with the terms of the contract or for any other cause, he shall promptly, after the sustaining of any such damage, make a written statement of the nature of the damage sustained, to the Engineer, and shall on or before the fifteenth day of the month following that in which the damage shall have been sustained, file with the Engineer an itemized statement of the details and amount of such damage, and unless such statement is made as thus required, his claim for compensation shall be forfeited and invalidated, and he shall not be entitled to payment on account of any such damage.

ARTICLE XXXIII ABANDONMENT OF WORK

If the work to be done under this contract shall be abandoned, or if this contract or any part thereof shall be sublet without the previous written consent of the Awarding Authority, or if the contract or any claim there under shall be assigned by the Contractor otherwise than as herein specified, or if at any time the Engineer shall be of the opinion and shall so certify in writing that the condition herein specified as to the rate of progress are not fulfilled, or that the work or any part thereof is unnecessarily or unreasonably delayed, or that the Contractor has violated any of the provisions of this contract, the Awarding Authority may notify the Contractor by a written order, with a copy mailed to the home office of the Surety, to discontinue all work, or any part thereof. Thereupon the Contractor shall discontinue such work or such part thereof as the Awarding Authority may designate, and the Awarding Authority may thereupon by contract or otherwise, as it may determine, complete the work, or any such part thereof, and charge the entire expenses of so completing the work or part thereof to the Contractor; and for such completion, the Awarding Authority, for itself or its contractors, may take possession of and use or cause to be used in the completion of the work, or part thereof, any of such materials, equipment, machinery, implements, and tools of every description as may be found at the location of said work.

All expenses charged under this article shall be deducted and paid by the Awarding Authority out of any monies then due or to become due the Contractor under this contract, or any part thereof; and in such accounting, the Awarding Authority shall not be held to obtain the lowest figures for the work of completing the contract or any part thereof, or for ensuring its proper completion, but all sums actually paid therefore shall be charged to the Contractor. In case the expenses so charged are less than the sum which would have been payable under this contract, if the same had been completed by the Contractor, the Contractor shall be entitled to receive the difference; and in case such expenses shall exceed the said sum, the Contractor shall pay the amount of the excess to the Awarding Authority.

ARTICLE XXXIV PRICES FOR WORK

The Awarding Authority shall pay and the Contractor shall receive the prices stipulated in the proposal attached hereto as full compensation for everything furnished and done by the Contractor under this contract, including all work required, but not specifically mentioned, and also for all loss or damage arising out of the nature of the work aforesaid, or from the action of the elements, or from any unforeseen obstruction or difficulty encountered in the prosecution of the work, and for all risks of every description connected with the work, and for all expenses incurred by or in consequence of the suspension or discontinuance of the work as herein specified, and for well and faithfully completing the work and the whole thereof, as herein provided.

ARTICLE XXXV MONEY MAY BE RETAINED

The Awarding Authority may keep any monies which would otherwise be payable at any time hereunder and apply the same, or so much as may be necessary therefore, to the payment of any expenses, losses, or damages, incurred by the Awarding Authority and determined as herein provided, and may retain, until all claims are settled, so much of such money as the Awarding Authority shall be of the opinion will be required to settle all claims filed with the Awarding Authority, its officers, and agents, relating to this contract.

ARTICLE XXXVI PARTIAL PAYMENTS

The Contractor shall prepare payment requisitions to submit to the Awarding Authority or his representative by the fifth day of each month. This payment requisition shall include all quantities of materials at unit bid prices constructed complete and in place during the previous month. The estimate shall be just and fair, based on actual quantities used to complete the work and the materials incorporated into the work during the previous calendar month. Payment may at any time be withheld if the work is not proceeding in accordance with this contract. Upon such estimate being made and certified by the Awarding Authority’s representative, the Awarding Authority will pay to the Contractor ninety (90) per cent of the amount stated in such estimate or certificate to be the value of the work therein certified to have been done, but the Awarding Authority may at all times reserve and retain out of any or all of said partial payment, all such sums as it is or may be authorized to reserve or retain. The making of any such estimates or payment thereon shall not be taken or construed as an approval or acceptance by the Awarding Authority of any work as estimated. All such payments shall be considered tentative only, subject to correction in the final estimate, and need not be based upon an accurate measurement. The Contractor shall be responsible for any loss or damage to any such material or equipment until the same has been completely installed, tested and accepted. ARTICLE XXXVII APPROVAL AND ACCEPTANCE OF WORK

Following the completion of this contract as such completion is defined herein and as soon thereafter as practicable, the Engineer will inspect the entire work in all parts and details, and if said work and all contract performances are found to be satisfactory and in accordance with the provisions and terms of the contract and specifications, the Engineer will certify the work as completed and will accept it upon behalf of the Awarding Authority but conditional upon the subsequent remedying of defects which may become manifest within a period of twelve (12) months following completion and as herein required. The certification of completion and the said acceptance of the work will be a pre-requisite to final payment hereunder.

Twelve months after the date of the certificate of acceptance as herein before set forth and as soon thereafter as practicable, the Engineer shall make a review and re- inspection of the work and performances and work shall be found satisfactory and the work not to have deteriorated through defects of workmanship or material, then the Engineer shall certify the release of the guarantee herein elsewhere specified, and such certification shall be a prerequisite to the release of the surety on the Contract Bond.

If, however, the review and re-inspection as herein set forth or any prior inspection discloses defects due to the non-fulfillment of this contract, or non-compliance with its requirements, the Engineer shall so notify the Contractor in writing and thereupon the Contractor shall, at his own expense, repair or replace and shall make good all defects of workmanship, materials and guarantee, and shall recite any noncompliance, and such repairs and fulfillment shall be a pre-requisite to the release of the guarantee and to the release of the surety of the Contract Bond. If, however, the Contractor shall, after the notice, refuse or neglect to make good the defects as notified and to the satisfaction of the Engineer, then the Awarding Authority may and is empowered to proceed in the manner prescribed in the event of abandonment or forfeiture of the work by the Contractor, and completion by the Awarding Authority and the payment of claims for material and labor and other expense as provided in such procedures shall be a prerequisite to the termination of guarantee, to the release of guarantee and to the release of the surety on the Bond.

ARTICLE XXXVIII SEMI-FINAL AND FINAL PAYMENT Within 65 days after the work has been completed to the satisfaction of the Engineer, he will make a final estimate of the amount of work done by the Contractor and of the value thereof. Such final estimate shall include the value of all work performed under the contract and all retained percentage, after deducting there from the total of all previous periodic or partial payments and all amounts to be retained to satisfy any and all outstanding claims or liens that have been duly filed against the Contractor. All prior estimates shall be subject to correction by this final estimate. After preparation, a copy of said final estimate shall be submitted to the Contractor for his approval and agreement.

If, after final inspection has been made, there are any payment or extra work items that are in dispute, either as to the quantity or value of the work performed hereunder, such items or claims may be excluded from the final estimate and payment for such disputed items may be deferred until such time as an agreement has been reached between the Contractor and the Awarding Authority or until such time as the claim has been adjudicated. In such cases, a semi-final estimate shall be prepared within the said period of 65 days after completion, covering the value of all work performed and all retained percentage on all items of the contract that are not in dispute but subject to the same deductions and retainers as set forth above and with all disputed items or claims excluded.

In the event that the work has been substantially completed and the project has been opened to public use by order of the Awarding Authority or its duly authorized agents, but final acceptance of the work is subject to delay because of minor uncompleted items which do not impair the usefulness of the project, a semi-final estimate shall be prepared within a like period of 65 days after such contract has been substantially completed and placed in public use. Such semi-final estimate shall include an estimate of the value of all work performed in accordance with the terms of the contract, including the amount of retained percentage withheld from previous partial payments but excluding the same deductions and retainers as set forth above; an estimate of the value of the work remaining to be performed and any items of work that may be in dispute. Payment for such excluded items or portions thereof may be deferred until such time as the remaining work has been satisfactorily completed or in the case of disputed items or claims until such time as an agreement has been reached.

If the Engineer delays or fails to prepare any final or semi-final estimate within the period of time specified herein, interest on the amount due the Contractor on any such final or semi-final estimate shall be computed and paid by the Awarding Authority at the rate of five (5%) percent per annum, beginning 66 days after the contract has been satisfactorily completed or the project has been substantially completed and opened to public use, as the case may be, and running until the date such estimate has been prepared and submitted to the Contractor for acceptance. The amount of such interest shall be included in the estimate when prepared.

Such final or semi-final estimates, however, shall not serve as a release of the Contractor or of his sureties from the required guarantee against defects of materials, workmanship, or other contract performances for a period of one (I) year from the date of acceptance.

ARTICLE XXXIX CLAIM FOR LABOR MATERIALS AND DAMAGE

The Contractor shall from time to time, as required by the Awarding Authority, furnish the said Awarding Authority with affidavits and satisfactory evidence that all persons who have done work or furnished materials under this contract, or have suffered damage on account of the Contractor's operations, have been fully paid or secured; and in case such evidence be not furnished as aforesaid, such amount as said Awarding Authority may consider necessary to meet the lawful claims of the persons aforesaid will be retained from the monies otherwise due said Contractor, until the liabilities aforesaid have been fully satisfied. It is understood and agreed, however, that the Awarding Authority hereby assumes no obligation toward such claimants, nor in any way undertakes to pay such claims out of any funds due or that may become due the Contractor, or out of its own funds.

ARTICLE XL WAVIERS

Neither the inspection of the Awarding Authority nor any of its agents, nor any orders, measurements, or certificate by the Engineer, nor any order by the Awarding Authority for the payment of money nor any payment for, nor acceptance of, the whole or any part of the work by the Awarding Authority, nor any extension of time nor any possession taken by the Awarding Authority or its employees, shall operate as a waiver of any provision of this contract, or of any power herein reserved to the Awarding Authority, or any right to damages herein provided, nor shall any waiver of any breach of this contract be held to be a waiver of any other or subsequent breach. Any remedy provided in this contract shall be taken and construed as cumulative; that is, in addition to each and every other remedy herein provided, and in addition to all other suits, actions or legal proceedings, the Awarding Authority shall also be entitled as of right to a writ of injunction against any breach of any of the provisions of this contract.

ARTICLE XLI LIABILITY OF AWARDING AUTHORITY

No person, firm or corporation, other than the signer of this contract as Contractor, now has any interest hereunder and no claim shall be made or be valid, and neither the Awarding Authority, nor any agent of the Awarding Authority, shall be liable for or be held to pay any money, except as herein provided. The acceptance by the Contractor of the payment of the final estimate shall operate as and shall be a release to the Awarding Authority, and every agent of the Awarding Authority, from all claim and liability to the Contractor for anything done or furnished for or relating to the work, or for any act or neglect of the Awarding Authority or of any person relating to or affecting the work, except the claim against the Awarding Authority for the remainder, if any there be, of the amounts kept or retained as herein provided.

ARTICLE XLII GUARANTY

The Contractor guarantees that the work to be done under this contract, and the materials to be furnished by him for use in the construction of the same, will be free from defects or flaws. This guaranty shall be for a period of one year from and after the date of completion. It is hereby, however, specially agreed and understood that this guaranty shall not include any repairs made necessary by any cause or causes other than defective work or materials furnished by the Contractor. The Contractor shall at all times within said period of guaranty keep the surface of the ground over this work, or adjacent thereto, in the position and condition required by this contract, and refill any settlement or erosion in the backfilling or any surface graded by him, due to any cause whatsoever, when so directed by the Engineer, should he fail to do so, the Awarding Authority may have said work done as described in Article XXXVIII. ARTICLE XLIII LEGAL ADDRESS OF CONTRACTOR

Both the address given in the bid and proposal submitted by the Contractor and the Contractor's office at or near the site of the work are hereby designated as places to either of which notices, letters, and other communications to the Contractor shall be certified, mailed, or delivered. The delivering at the above-named place, or depositing in a post-paid wrapper directed to the first-named place, in any post office box regularly maintained by the Post Office Department, of any notice, letter, or other communication to the Contractor, shall be deemed sufficient service thereof upon the Contractor, and data of said service shall be the date of such delivery or mailing. The first-named address may be changed at any time by an instrument in writing executed, and acknowledged by the Contractor and delivered to the Engineer. Nothing herein contained shall be deemed to preclude or render uncooperative the service of any notice, letter, or other communication upon the Contractor personally.

ARTICLE XLIV RESPONSIBILTY FOR UTILITY PROPERTY AND SERVICE

At points where the Contractor's operations are adjacent to properties or railway, telegraph, telephone, and power companies, or are adjacent to other property, damage to which might result in considerable expense, loss, or inconvenience, work shall not be commenced until all arrangements necessary for the protection thereof have been made. The Contractor shall cooperate with the owners of any underground or overhead utility lines in their removal and rearrangement operations in order that these operations may progress in a reasonable manner, and that duplication of rearrangement work may be reduced to a minimum, and that service rendered by those parties will not be unnecessarily interrupted. The approximate locations of the existing major utilities are shown on the drawings. In addition to these, there may be others that are not shown on the drawings. It shall be the responsibility of the Contractor to cooperate closely with all utility companies involved and shall ascertain the exact locations of all utilities prior to excavation. All existing utilities shall be protected from damage during construction and, if damaged, shall be repaired by the Contractor at his own expense.

IN WITNESS WHEREOF, Town of Acton has caused these present, and five other original duplicate contracts of like tenor and date, to be signed in its name and behalf, and its official seal hereunto affixed by its officers thereunto duly authorized; and the said Contractors of like tenor and date, to be signed in its name and behalf, and its official seal hereunto affixed by

The work to be done under this Item consists of the monitoring and protection of turtles during the construction of highways and bridges or other areas designated by the Engineer and inaccordance with applicable environmental permits.

This Item is applicable to the site of Br. No. A-02-009 which lies withinthe Wood Turtle estimated habitat.

Construction Methods This work shall consist of three (3) primary tasks as follows:

1. Monitoring of Active Construction Areas:

Prior to the start of any construction activity, the contractor shall submit to the Engineer for approval the name and qualifications of the proposed Turtle Monitorfor the project. The Turtle Monitor (Monitor) shall be a qualified biologist approved by the Natural Heritage and Endangered Species Program (NHESP) that has experience in rare turtle ecology and turtle management during construction projects. The primary objective of the Turtle Monitor is to ensure that impacts to the wood turtle are avoided to the greatest extent possible during the reconstruction. The Monitor shall acquire a Scientific Collection permit from the NHESP to capture, handle and relocate wood turtles and other state-listed species, as appropriate.

Prior to construction within and in proximity to turtle habitat, and prior to any re-start of construction after a temporary shut-down, the Monitor shall be responsible for searching the work areas (inside all erosion and sedimentation barriers and cofferdams and along the outer edge) for any turtles and, pursuant to a Scientific Collection permit, shall relocate any turtles or protected species to a suitable habitat outside of the work zone during the turtle active season (April15 through October15) as detailed below.

Land Under Water — The Monitor shall be present as in-water barriers are installed (eg, cofferdams.) Once installed, the Turtle Monitor shall search withinthe cofferdams and inthe vicinityto remove any turtles encountered and, again, afterthe area(s) are de-watered. Wood Turtles may be encountered inthe water throughout the active season. Work shall be avoided during the turtle inactive season (October 15 through April 15).

Bank — Wood Turtles over-winter in overhanging banks and can be difficultto see in these areas. The Monitor shall visually search the areas immediately prior to any work including physical bank alteration and vegetation cutting. Work shall be avoided during turtle inactive season (October 15 through April 15). To the extent possible, clearing and grubbing shall be conducted between May 1 and August 31.

Vegetated Areas within 200 feet of the Stream — Wood turtles forage and rest in vegetated areas along the stream. In any area where machinery willenter over vegetated ground, the Monitorshould sweep for turtles in advance of machinery moving intoand out of areas near the stream. If vegetation will be cut or vegetation will be herbicided, the Monitor must sweep through prior to work and remove any turtle. The frequency of sweeps is tied to the number of initiations of vegetation alteration and can be minimized by phasing allvegetation afteration into a single event. Work shall be avoided during turtle inactive season (October15 through April 15). To the extent possible, clearing and grubbing shall be conducted between May 1 and

16 August31.

Stockpiles of dirt,loam, sand— From June 1through July 1, stockpiles should be fullyencircled during non-work hours with a turtle barrier to prevent turtles from nesting in this material.

Work stoppage greater than 48 hours during month of June and month of September— Turtle Monitor shall search in work zone for turtles and provide guidance about potential additional protective measures as noted above in “stockpiles...” to prevent turtles from nesting in work zones or to accommodate discovered nest.

SymbolicBarrier— For large projects that willinvolvemany contractors and vehides coming to the site, it may be beneficial to install symbolic barriers to define parking areas and areas that must be avoided. Such barriers may also be required to protect nesting found withinthe work zone.

Inthe event of finding an injured turtle, the turtle shall be transported to a suitable veterinarian. In the event of finding a turtle with a radio transmitter, NHESP and the contact on the transmitter shall be alerted immediately.

A written report shall be provided to the Engineer followingeach inspection. Any and all rare species encountered at the site should be reported to NHESP on the rare Animal Observation Form as soon as possible. Furthermore, the NHESP shall receive a report notifyingthem ofthe initiationof work and after the completion of work indicating the dates of all searches, species observed, and any corrective measures taken. The Turtle Monitormay modifythe above noted plan, with NHESP written approval, to accommodate specific construction sequencing details of a particular project.

2. Implementation of a Worker Training Program and Notification Procedure:

There shall be the implementation of a site worker training program. This training program shall be developed and presented by the Turtle Monitor prior to the start of the wood turtle active period (i.e., prior to April 15). Construction crews, project foreman, and site engineers shall participate in a special training session aimed at making them aware of the ongoing rare species concerns and the various protective measures in place to safeguard the wood turtle.

To help facilitate learning of the important concepts presented during the training, the Turtle Monitorshall produce a laminated ‘informationalsheet’ on the wood turtle to be distributed to the workers during the training session and posted at conspicuous locations at the project site. This informational sheet shall include representative photographs and diagnostic features of the wood turtle to aid identification, an outline of the notification procedure, and contact information for the Turtle Monitor, NHESP, and the specialty care facilities presented in the previous section.

3. Installation of Appropriate Barrier Fencing:

Barrier fencing is an integral part of the protection plan strategy as it serves to intercept migrating turtles before they reach the work area, thus reducing the potential for mortality or injuryfrom the construction activity. Turtles willfrequently tum around when they encounter an impassable object that directs them ina direction that is opposite (e.g., 180 degrees from)their desired destination.

17 Smaller gauge (e.g., 5/8-inch) mesh sift fencing shall be used for the turtle barrier.
