(A) With respect to award of any contract for the construction, reconstruction, improvement, enlargement, alteration, repair, painting, or decoration of a public improvement made by the state, or any county, township, municipal corporation, school district, or other political subdivision, or any public board, commission, authority, instrumentality, or special purpose district of or in the state or a political subdivision or that is authorized by state law, the award, and execution of the contract, shall be made within sixty days after the date on which the bids are opened. The failure to award and execute the contract within sixty days invalidates the entire bid proceedings and all bids submitted, unless the time for awarding and executing the contract is extended by mutual consent of the owner or its representatives and the bidder whose bid the owner accepts and with respect to whom the owner subsequently awards and executes a contract. The public owners referred to in this section shall include, in the plans and specifications for the project for which bids are solicited, the estimate of cost. The bid for which the award is to be made shall be opened at the time and place named in the advertisement for bids, unless extended by the owner or its representative or unless, within seventy-two hours prior to the published time for the opening of bids, excluding Saturdays, Sundays, and legal holidays, any modification of the plans or specifications and estimates of cost for the project for which bids are solicited is issued and mailed or otherwise furnished to persons who have obtained plans or specifications for the project, for which the time for opening of bids shall be extended one week, with no further advertising of bids required. The contractor, upon request, is entitled to a notice to proceed with the work by the owner or its representative upon execution of the contract. No contract to which this section applies shall be entered into if the price of the contract, or, if the project involves multiple contracts where the total price of all contracts for the project, is in excess of ten per cent above the entire estimate thereof, nor shall the entire cost of the construction, reconstruction, repair, painting, decorating, improvement, alteration, addition, or installation, including changes and estimates of expenses for architects or engineers, exceed in the aggregate the amount authorized by law.
The unit or lump sum price stated in the contract shall be used in determining the amount to be paid and shall constitute full and final compensation for all the work.
Partial payment to the contractor for work performed under the lump sum price shall be based on a schedule prepared by the contractor and approved by the architect or engineer who shall apportion the lump sum price to the major components entering into or forming a part of the work under the lump sum price.
Partial payments to the contractor for labor performed under either a unit or lump sum price contract shall be made at the rate of ninety-two per cent of the estimates prepared by the contractor and approved by the architect or engineer. All labor performed after the job is fifty per cent completed shall be paid for at the rate of one hundred per cent of the estimates submitted by the contractor and approved by the architect or engineer.
The amounts and time of payments of any public improvements contract made by the state or any county, township, municipal corporation, school district, or other political subdivision, or any public board, commission, authority, instrumentality, or special purpose district of or in the state or a political subdivision or that is authorized by state law, except as provided insection 5525.19 of the Revised Code, shall be governed by this section and sections 153.13and 153.14 of the Revised Code. If the time for awarding the contract is extended by mutual consent, or if the owner or its representative fails to issue a timely notice to proceed as required by this section, the owner or its representative shall issue a change order authorizing delay costs to the contractor, which does not invalidate the contract. The amount of such a change order to the owner shall be determined in accordance with the provisions of the contract for change orders or force accounts or, if no such provision is set forth in the contract, the cost to the owner shall be the contractor’s actual costs including wages, labor costs other than wages, wage taxes, materials, equipment costs and rentals, insurance, and subcontracts attributable to the delay, plus a reasonable sum for overhead. In the event of a dispute between the owner and the contractor concerning such change order, procedures shall be commenced under the applicable terms of the contract, or, if the contract contains no provision for resolving the dispute, it shall be resolved pursuant to the procedures for arbitration in Chapter 2711. of the Revised Code, except as provided in division (B) of this section. Nothing in this division shall be construed as a limitation upon the authority of the director of transportation granted in Chapter 5525. of the Revised Code
(B) If a dispute arises between the state and a contractor concerning the terms of a public improvement contract let by the state or concerning a breach of the contract, and after administrative remedies provided for in such contract and any alternative dispute resolution procedures provided in accordance with guidelines established by the executive director of theOhio facilities construction commission are exhausted, the contractor may bring an action to the court of claims in accordance with Chapter 2743. of the Revised Code. The state or the contractor may request the chief justice of the supreme court to appoint a referee or panel of referees in accordance with division (C)(3) of section 2743.03 of the Revised Code.
