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-3.02CONSTRUCTION DOCUMENTS TO SUCCESSFUL BIDDER
The bidders on each Contract advertised by the Administration are responsible to download the Plans, Invitation for Bids Books, Cross Sections (if provided), and As-Built Plans (if provided) during the bidding process from the websites listed elsewhere in the Invitation for Bids. Upon award and if requested, the Administration will provide the successful bidder electronic copies of Plans, Invitation for Bids Books Cross Sections (if included), and As-Built Plans (if included).
TC-3.03RIGHTS IN THE USE OF MATERIALS FOUND ON THE
PROJECT The Contractor, with the approval of the Engineer may use on the project any excavated stone, gravel, sand, or other material conforming to the requirements of the Contract Documents. 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 not excavate nor remove any material that is not within the limits of excavation, as indicated by the slope and grade lines, without written authorization from the Engineer.
TC-3.04SAFETY HAZARDS IN CONFINED SPACES
The Contractor shall be responsible for gas detection in and ventilation of confined spaces. When procedures require workers to enter confined spaces such as steel or concrete box section type superstructures, particularly when the interior is closed off at both ends, the Contractor shall be cognizant of the potential health hazards. 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. The Contractor shall apply mechanical ventilation continuously to the confined space during occupancy to maintain the proper oxygen content and shall conduct air tests periodically during the occupancy. 86
