Okla. Stat. tit. 11, § 11-36-225: Replacement bonds - Repairs

Upon acceptance of the improvements and before the final payment

of the contract price, the governing body shall require the

contractor performing the work to make and execute a good and

sufficient surety bond, or deposit sufficient securities or

obligations of the United State of America or of the State of

Oklahoma or some municipal subdivision thereof, to be approved by

the governing body in the sum as determined by the governing body,

but in no case to be less than ten percent (10%) of the contract

price. The bond shall be conditioned for the immediate

reimbursement to the municipality by the contractor for the

maintenance of the improvements against any failure due to defective

workmanship or materials for a period of three (3) years from the

time of its completion and acceptance. Whenever any repairs of the

improvements due to defective workmanship or materials are deemed

necessary by the governing body, they shall order the same to be

made under the supervision of the municipal engineer and the costs

thereof certified to by the engineer. When such repairs have been

approved by the governing body, the contractor and his bondsmen

shall be notified of the amount expended and shall immediately

become liable therefor.
