TC-3.01GOVERNING ORDER OF CONTRACT DOCUMENTS

The Contract Documents, including but not limited to the Standard Specifications, the Special Provisions Inserts, the Plans, Special Provisions, and all supplementary documents are essential parts of the Contract, and a requirement occurring in one is as binding as though occurring in all. They are intended to be complementary and to describe and provide for a complete work. In the event of any discrepancy between the drawing and figures written thereon, the figures, unless obviously incorrect, will govern over scaled dimensions. In the event of any discrepancy between the various Contract Documents, the governing order from highest to lowest shall be Special Provisions, Plans, Special Provisions Inserts, and Standard Specifications. General Provisions will govern over all Contract Documents unless expressly provided for in the Contract.

TC-3.03RIGHTS IN THE USE OF MATERIALS FOUND ON THE

When these materials are used for select, capping, modified, or common borrow and conform to the pertinent materials Specifications, payment will only be made at the Contract unit price for the class of excavation from which the materials are obtained. In the event these materials are processed through a crushing, screening, washing, or sorting plant for use as another pay item, the Contractor will be paid both for the excavation of such materials at the Contract unit price and at the Contract unit price for which the material is used. The Contractor shall replace with other acceptable material all of the portion of the excavated material removed and used that was needed for use in the embankments, backfills, approaches, or otherwise, at no additional cost to the Administration. 85 TC - SECTION 3: SCOPE OF WORK If however, these materials are not processed and paid for as described in the preceding paragraph, and their use creates a shortage of embankment, backfill, approaches, or other material, the Contractor shall provide acceptable replacement material for all the material needed for embankments, backfills, approaches, or otherwise. In this case, the replacement material shall be paid for at the unit price for the item the Class 1 Excavation is used for, or the unit price bid for the Class 1 Excavation, whichever is the lower unit price bid.

The Contractor shall adhere to all applicable MOSH regulations. The Contractor shall have approved detecting devices available and shall conduct tests for oxygen content and presence of gases, such as combustible gas, carbon dioxide, methane, carbon monoxide, and hydrogen sulfide whenever any fabrication, erection, or inspection operations are to be performed within the confined spaces.
