Iowa Statutes § 73A.8 Enforcement of performance

After any contract for any public improvement has been completed and any five persons interested request it, the appeal board shall examine into the matter as to whether or not the contract has been performed in accordance with its terms, and if on such investigation it finds that said contract has not been so performed, and so reports to the body letting such contract, it shall at once institute proceedings on the contractor's bond for the purpose of compelling compliance with the contract in all of its provisions.
