105.04 Coordination of Specifications. The General Provisions, Special Provisions, Plans, Supplemental Specifications, Standard Specifications, and all supplemental documents affecting the work, duly issued by the Engineer to the Contractor, are essential parts of the contract, and a requirement occurring in one is as binding as if occurring in all. They are intended to be complementary and to describe and provide for a complete work. In case of discrepancy, numerical dimensions will prevail over scaled dimensions and the parts of the contract will prevail in the following order:

1. General Provisions (SF 23A)

2. Special Provisions

3. Plans

4. Supplemental Specifications

5. Standard Specifications

In Clause 2, of SF 23A the term "specifications” is interpreted to mean job specifications of a nature corresponding to "special provisions”, as defined in subsection 101.02 and not the standard specifications that are of general application.

The Contractor shall take no advantage of any apparent error or omission in the plans or specifications. In the event the Contractor discovers such an error or omission, he shall immediately notify the Engineer. The Engineer will then make such corrections and interpretations as may be deemed necessary for fulfilling the intent of the plans and specifications.

The Government will notify all utility companies, all pipe line owners or other parties affected, and endeavor to have all necessary adjustments of the public or private utility fixtures, pipe lines, and other appurtenances within or adjacent to the limits of construction, made as soon as practicable.

Water lines, gas lines, wire lines, service connections, water and gas meter boxes, water and gas valve boxes, light standards, cableways, signals, and all other utility appurtenances within the limits of the proposed construction which are to be relocated or adjusted are to be moved by others at their expense, unless otherwise provided in the contract.

It is understood and agreed that the Contractor has considered in his bid all of the permanent and temporary utility appurtenances in their present or relocated positions as shown on the plans and that no additional compensation will be allowed for any delays, inconvenience, or damage sustained by him due to any interference from the said utility appurtenances or the operation of moving them.

Note: The contract may indicate various utility items, certain of which are to be relocated or adjusted by the utility owner and others

which are to be relocated or adjusted by the Contractor. The provisions will indicate the means of adjudication, if any, in failure by the utility owners to comply with their responsibi relocating or adjusting their facility.

105.07 Other Contracts.

See SF23A General provisions.

105.08 Construction Stakes, Lines and Grades. The En will set such initial construction stakes establishing lines, slope continuous profile-grade in road work, and reference lines and marks for bridge work, culvert work, protective and accessory tures and appurtenances as he may deem necessary, and will f the Contractor with all necessary information relating to lines, and grades. These stakes and marks will constitute the field con and in accordance with which the Contractor shall establish necessary controls and perform the work.

The Contractor will be held responsible for the preservation stakes and marks, and if any of the construction stakes or mark been carelessly or willfully destroyed or disturbed by the Cont the cost to the Government of replacing them may be charged a him and may be deducted from the payment for the work.

The Contractor shall notify the Engineer of apparent erro covered in initial stakeout before the affected work is begun. S work be performed in accordance with inaccurate initial stakeout by the Engineer and not discovered by the Contractor, payme such work and any directed correction thereof will be made at a ble unit prices of the contract unless such work differs substa from that described on the plans or in the specifications, in whic the provisions of subsection 109.03 or 109.04 will apply.

Section 106.-CONTROL OF MATERIAL

106.01 Source of Supply and Quality Requirements.

Unless otherwise provided, all materials used on the work shall be furnished by the Contractor from sources of his choice, except for Borrow, Case 1, which shall be obtained in accordance with subsection 203.03 (1). In order to expedite the inspection and testing of materials, the Contractor shall notify the Engineer of his proposed sources of

materials at the earliest date possible. If it is found after trial that sources of supply for previously approved materials do not produce uniform and satisfactory products or if the product from any source proves unacceptable at any time, the Contractor shall furnish materials from other sources.

106.02 Local Material Sources.

Possible sources of local materials may be shown on the plans or described in the special provisions. The quality of material in such deposits will be acceptable in general, but the Contractor shall determine for himself the amount of equipment and work required to produce a material meeting the specifications. It shall be understood that it is not feasible to ascertain from samples the limit for an entire deposit, and that variations shall be considered as usual and are to be expected. The Engineer may order procurement of material from any portion of a deposit and may reject portions of the deposit as unacceptable.

Unless otherwise provided, the Government will acquire and make available to the Contractor the right to take materials from the sources shown on the plans or described under special provisions, together with the right to use such property as may be specified, for plant site, stockpiles and hauling roads.

If the Contractor elects to use material from sources other than those shown on the plans or described in the special provisions, he shall acquire the necessary rights to take materials from the sources and shall bear all costs related thereto including those for development and exploration and any costs which may result from an increase in length of haul. The use of material from such sources will not be permitted until the Engineer determines, from representative samples obtained and tested at the expense of the Contractor, that an adequate amount of satisfactory materials are available in the source. Additional samples may be required of the Contractor for inspection and testing at Government expense, prior to approval of and authorization to use the

source.

If crushed aggregate is produced from local gravel pits, all oversize material encountered therein with diameters of 12 inches (305 mm) or less shall be crushed and used.

When work areas, gravel pits or other than commercially operated borrow pits are located in or adjacent to live streams or other bodies of water, operations at the sites shall be so controlled, both during and after completion of the work, that erosion will be minimized and sediment will not enter streams or other bodies of water. This may require segregating such areas by a dike or other barrier, treatment of pollutants by filtration, a settling basin or other means sufficient to reduce the sediment content to not more than that of the body of water into which it is discharged.
