The determination of the Engineer and Director shall be final upon all questions of the amount and value of extra work. If a unit price does not exist, payment for extra work will be actual cost plus fifteen (15%) per cent. No allowance will be made for overhead costs.

The Contractor hereby agrees that 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 Director, or if the Contract or any claim thereunder shall be assigned by the Contractor otherwise than as herein specified, or at any time the Director shall be of the opinion that the work is unnecessarily or unreasonably delayed, or that the Contractor is willfully violating any of the conditions or agreements of this Contract, or is not executing the Contract in good faith, or is not making such progress in the execution of the work as to indicate its completion within the required time, the Director shall have the power and right to notify the Contractor to discontinue all work or any part thereof under this Contract. Thereupon the Contractor shall discontinue the work or any such parts thereof as the Director shall have the power, by contract with or without advertising, day labor or otherwise as he/she may determine, to employ such labor and obtain such tools and appliances as he/she may deem necessary to work at and be used to complete the work herein described or such parts thereof as the Director may deem necessary, and to use such tools and materials of every description as may be found upon the line of work, and to procure other materials for the completion of the same, and to charge the expense of said labor, tools and materials to the Contractor; and the expense so charged shall be deducted and paid by the City out of such monies as may be due or may become due the Contractor under this Contract or any part thereof. In case such expense is more than the sum which would have been payable under this Contract, if the same had been completed by the Contractor, then the Contractor shall pay the amount owed by the City under this Contract at the time the Contractor is notified in writing to discontinue the work or any part thereof, plus the amount of the Bond executed by the Contractor for the performance of the Contract.

20.34 PAYMENT FOR MATERIALS:

Payments will be made in accordance with the price stated in the Contract. The Contractor may include requests for payment of material delivered to the job site when such requests are accompanied by invoices substantiating the requests for material payment satisfactory to the City.

If at any time within the period of the guaranty, any other part of the work constructed under the terms of this Contract shall in the opinion of the Director of Public Works require repairing, the Director shall notify the Contractor in writing to make the required repairs. If the Contractor shall neglect to make such repairs to the satisfaction of the Director within the time limit as set forth in the notice in writing to the Contractor of the required repairs, then the Director of Public Services may make the necessary repairs, by contract or otherwise, and the City shall have a claim against the Contractor in the amount of the expense incurred by the City in making such repairs.

It is hereby, however, specifically agreed and understood that this guaranty shall not include any repairs made necessary by any cause or causes other than defective work or materials.

A work day shall be any day, other than a State of Maine legal holiday or Sunday, on which weather and working conditions permit the Contractor to make effective use of not less than seventy-five (75%) per cent of the hours during the regular work day.

The length of any open excavation shall not exceed fifty (50) linear feet, unless authorized by the Engineer. If the excavation becomes a hazard, or if it excessively restricts traffic at any point, the Engineer may require special construction procedures such as limiting the length of open excavation, prohibiting the stacking of excavated material in the street, and/or requiring

30-1 that the excavation shall not remain open overnight. The Contractor shall hold the City harmless from all liability related to open excavations.

Open excavations will be allowed overnight, except they shall be backfilled for weekends, when they are within one hundred and fifty (150) feet of an intersection, or if they present a hazard to traffic as determined by the Engineer.

The Contractor shall take precautions to prevent injury to the public due to open excavations. All excavations, excavated material, equipment, or other obstacles that could be dangerous to the public shall be well lighted at night. Open excavations shall be allowed overnight, except on heavily traveled streets, or when ordered by the Engineer.

30.05 MAINTENANCE OF TRAFFIC

The Contractor shall perform his/her work to maintain at least one lane available for the use of traffic and emergency vehicles at all times. Completely closing the traffic lanes will not be permitted except under special permission from the Director of Public Works, Fire Chief and the Police Chief.

In case of cutting or unavoidable damage to branches, limbs, and trunks of trees, the cut or damaged portions shall be neatly trimmed and covered with an application of grafting wax or tree healing paint, as directed.

Cultivated hedges, shrubs, and plants that might be damaged by the Contractor’s operations shall be protected by suitable means, or shall be dug up and temporarily replanted and cared for. After the construction operations have been substantially completed, they shall be replanted in their original positions and cared for until growth is re-established. If cultivated hedges, shrubs and plants are injured to such a degree as to affect their growth or diminish their usefulness, they shall be replaced by items of kind and quality at least equal to that existing at the commencement of work. This work shall be performed at the expense of the Contractor. All work shall be inspected and approved by the City Arborist, and it shall not be considered complete until the Contractor has completed all work to his/her satisfaction.

The Contractor shall preserve all property pins and monuments which are located outside the work area. If property pins or monuments are encountered in the work area where side slopes extend to or beyond the right-of way line, the Contractor shall halt work in the immediate area long enough for the Engineer to take such data as necessary to re-establish the location of the pin or monument. The Engineer will reset such pin or monument after completion of the work at no expense to the Contractor. If, however, pins or monuments outside the work area become damaged or lost, the restoration or replacement of such items shall be done by a licensed surveyor and shall be the Contractor’s responsibility.

Posts will be spaced a maximum of 10 feet apart at the barrier location and driven securely into the ground (minimum of 12 inches). When extra strength fabric is used without the wire support fence, post spacing will not exceed 6 feet. e. A trench will be excavated approximately 4 inches wide and 4 inches deep along the line of posts and upslope from the barrier. f. When standard strength filter fabric is used, a wire mesh support fence will be fastened securely to the upslope side of the posts using heavy duty wire stapled at least 1 inch long, tie wires or hog rings. The wire will extend more than 36 inches above the original ground surface. g. The standard strength of filter fabric will be stapled or wired to the fence, and 8 inches of the fabric will be extended into the trench. The fabric will not extend more than 36 inches above the original ground surface. Filter fabric will not be stapled to existing trees. h. When extra strength filter fabric and closer post spacing are used, the wire mesh support fence may be eliminated.

Mulch: Mulch with weed free hay or straw at 1.0 - 2.0 tons per acre. f. Anchor mulch with mulch netting installed per manufacturers recommendations. g. If permanent vegetated stabilization cannot be established due to the season of the year, all exposed and disturbed areas not to undergo further disturbance are to have dormant seeding applied and be temporarily mulched to protect the site. 3. The following methods may be used to perform a dormant seeding: a. Prepare the seedbed, add the required amounts of lime and fertilizer, then mulch and anchor. After the first killing frost and before snow fall, broadcast or hydroseed the selected seed mixture. Double the regular seeding rates for this type of seeding. b. When soil conditions permit, between the first killing frost and before snow fall, prepare the seedbed, lime and fertilize, apply the selected seed mixture, and mulch and anchor. Double the regular seeding rates for this type of seeding. c. Dormant seedings need to be anchored extremely well on slopes, ditch bases and areas of concentrated flows. d. Dormant seeding requires inspection and reseeding as needed in the spring. All areas where cover is inadequate must be immediately reseeded and mulched as soon as possible.

C. No dry cement or mixture of sand and cement shall be applied to surface of any concrete slab to absorb moisture.

3.10 CURING AND PROTECTION:

A. Protect newly placed concrete against low and high temperature effects and against rapid loss of moisture. Cure all concrete for at least seven days at a temperature of at least 50 degrees F by curing methods approved by the Landscape Architect.

B. Acceptable methods for curing vertical or near vertical surfaces may be: by maintaining wood forms continuously wet during curing period, by wrapping with continuous .006" polyethylene with taped joints or as approved by the Landscape Architect.

3.11 FORM REMOVAL:

A. Forms shall be removed without damage to concrete. The Contractor shall be responsible for the safety of the construction during and after form removal. No act of the Landscape Architect shall relieve him of this responsibility.

B. Protect corners from damage after form removal by boxing, corner boards or other means approved by the Landscape Architect.

C. Formwork for piers, pilasters, walls, beam sides and other parts not supporting the weight of concrete may be removed as soon as the concrete has reached 30% of its specified 28- day strength, but not before 2 days, provided it is properly cured and protected thereafter.

D. Re-shoring shall remain in place until concrete has reached its specified 28-day strength and until members can safely support their weight and the load thereon. Until the 28-day strength has been achieved, all concrete shall be protected from shock, vibration and heavy loads.

3.12 CUTTING OF HOLES:

A. Cut holes required by other trades in any cast-in-place concrete which did not receive sleeves. Use a core drilling process or sawing process which produces clean sharp edges and the minimum hole size which accommodates the piping, conduit, or equipment requiring the opening.

B. Obtain approval of Landscape Architect before cutting any holes for any trades.
