State highways shall be constructed or improved by contract. Upon the completion and final adoption or approval, as provided by law, of the plans and specifications for the construction or improvement of a state highway, contracts therefor shall be executed as provided herein.
When such order on contract provides for similar items of work or materials which increase or decrease the itemized quantity provided for in the primary contract, the price to be paid therefor shall not exceed the unit bid price in the primary contract for such items. Agreed prices for new items of work or materials may be incorporated in the order on contract as the commissioner of transportation may deem them to be just and fair and beneficial to the state.
Whenever the commissioner of transportation also determines that in the cases herein provided it is impracticable for him to ascertain in advance the just and fair price to be paid by the state for new items of work or materials, the order on contract therefor may provide for performance of the work and the furnishing of the materials and equipment, in which event the contractor shall keep and shall make available at all times to the commissioner of transportation such accounting records, data and procedure as may be required by the commissioner of transportation. An estimate of the value of such work and the furnishing of materials and equipment shall be submitted by the commissioner of transportation to the state comptroller who is hereby empowered to approve such estimate. Partial and final payments shall be made upon proper records and data itemized as hereinbefore indicated.
Before any final accounting shall become effective, a supplemental contract and final agreement shall first be approved by the comptroller, and filed in his office. The director of the budget may at his discretion require the commissioner of transportation to submit periodic summaries of and reports on the scope and status of highway projects in such form and at such intervals as he may require, including any and all contract documents.
Any amount fixed in the determination to be paid to the contractor shall be deemed to be a special item to be incorporated in a final supplemental contract and shall be payable from monies available for construction and reconstruction of state highways, on the audit and warrant of the comptroller on vouchers approved by the commissioner of transportation.
