Ohio Revised Code Title VII. Municipal Corporations § 735.06

Bids for work under the supervision of the department of public service shall be opened at the time, date, and place specified in the notice to bidders or specifications and shall be publicly read by the director of public service or a person designated by him. The time, place, and date of bid openings may be extended to a later date by the director of public service, provided that written or oral notice of the change shall be given to all persons who have received or requested specifications no later than ninety-six hours prior to the original time and date fixed for the opening.

Each bid shall contain the full name of each person interested in it and shall be accompanied by a sufficient bond or certified check, cashier's check, or money order on a solvent bank or savings and loan association that if the bid is accepted a contract will be entered into and its performance properly secured unless the bid is for a contract for the construction, demolition, alteration, repair, or reconstruction of a public improvement, in which case it shall meet the requirements of section 153.54 of the Revised Code. If the work bid embraces both labor and material, such items shall be separately stated with the price thereof.

The director may reject any bid. Where there is reason to believe there is collusion or combination among bidders, the bids of those concerned therein shall be rejected.
