Ohio Rev. Code § 167.081
A regional council may enter into a contract that establishes a unit price for, and provides upon a per unit basis, materials, labor, services, overhead, profit, and associated expenses for the repair, enlargement, improvement, or demolition of a building or structure if the contract is awarded pursuant to a competitive bidding procedure of a county, municipal corporation, or township or a special district, school district, or other political subdivision that is a council member; a statewide consortium of which the council is a member; or a multistate consortium of which the council is a member.
A public notice requirement pertaining to the contract shall be considered as having been met if the public notice is given once a week for at least two consecutive weeks in a newspaper of general circulation within a county in this state in which the council has members and if the notice is posted on the council's internet web site for at least two consecutive weeks before the date specified for receiving bids.
A county, municipal corporation, or township and a special district, school district, or other political subdivision that is a council member may participate in a contract entered into under this section. Purchases under a contract entered into under this section are exempt from any competitive selection or bidding requirements otherwise required by law. A county, municipal corporation, or township or a special district, school district, or other political subdivision that is a member of the council is not entitled to participate in a contract entered into under this section if it has received bids for the same work under another contract, unless participation in a contract under this section will enable the member to obtain the same work, upon the same terms, conditions, and specifications, at a lower price.
