104.07Coordination of Contract Documents. The FAR, TAR, Special Contract Requirements ( SCR) , plans, and Standard Specifications are contract documents. A requirement in one document is binding as though occurring in all the contract documents. The contract documents are intended to be complementary and to describe and provide for a complete contract. In case of discrepancy, calculated and shown dimensions govern over scaled dimensions. The contract documents govern in the following order:

(a)FAR;

(b)TAR;

(c)SCR;

(d)Plans; and

(e)Standard Spec ifications .

104.08Load Restrictions . Follow the requirements of FAR Clause 52.236- 10 Operations and Storage Areas. Comply with legal load restrictions while hauling material and equipment on public roads and bridges to and from the project. Regardless of the legal or posted load limit, control loads to prevent damage to existing and new infrastructure within the project limits. Obtain necessary oversize or overweight vehicle permits and escorts for moving oversized or overweight loads. Provide a copy of the permits and associated loading calculations for roads and bridges within the project limits . A special permit does not relieve the Contractor of liability for damage resulting from moving or using material or equipment to or within the job site. Unless otherwise permitted, do not operate equipment or vehicles that exceed the legal load limits over new or existing structures, or pavements within the project. Ensure loads do not damage subgrade or utilities. Replace or restor e infrastructure damaged during operations to original condition.

104.09Construction Loading of Structures. Protect new and existing structures within the project limits from construction loads. Construction loads include, but are not limited to, the weight of cranes, trucks, paving equipment, other heavy construction, or material delivery equipment, as well as the delivery or storage of materials placed on or adjacent to the structure or parts thereof during the various stages (phases) of the work. If construction loads are planned to be located on or adjacent to a structure to be protected, determine the anticipated construction load, the construction loading capacity of the structure, and the effects the 25 construction load will have on the structure. Con sider the sequencing of the work, including construction phasing. If the loading capacity of the structure is not provided, determine the appropriate loading capacity information. Submit drawings and calculations for approval according to Subsection 104.06(a)(1) that bear the seal and signature of a professional engineer who is proficient in the applicable design field before starting work.

104.10Inspec tion at the Plant. Work may be inspected at the point of production or fabrication. Manufacturing plants may be inspected for compliance with specified manufacturing methods. Material samples may be obtained for laboratory testing for compliance with qual ity requirements. Allow entry at all times to the parts of the plant producing the work.

104.11Other Contracts. Follow the requirements of FAR Clause 52.236- 8 Other Contracts.
