Okla. Stat. tit. 74, § 74-581: Contracts by department or institution with another for

work - Payment - Disposition of proceeds.

That any department of the state government or any state

institution may contract with any other department of state

government or institution having under its control the personal

services, labor and equipment, machinery or other facilities to

perform needed work for or on behalf of the state or its

subdivisions, department or institutions, when such work may be

performed by the use of machinery, equipment, material and/or labor

of the department or institution under its control contracting to

furnish such service by the use of such facilities of its own, or

those of any institution of the state under its control. The

department or institution or subdivision obtaining and receiving

such services shall pay or otherwise compensate the department or

institution performing the work for the fair value thereof,

including the cost of material used and proper compensation by

payment or exchange for any personal services, labor, equipment and

material employed in performing such work or services; which said

funds shall be deposited in a special depository account to be kept

separately from all other collections and may be expended by the

departments, subdivisions or institutions performing the services by

voucher issued by said department or institution and drawn on the

State Treasurer; provided, however, that when such services are

performed by any department or institution having a revolving fund,

such payments may be credited to and become a part of such revolving

fund.
