Iowa Code § 26.15

A governmental entity may enter into annual contracts with multiple contractors for structure demolition projects, with each project having a total estimated cost of one hundred thousand dollars or less, or each project having a total estimated cost equal to or less than the competitive bid threshold as established in section 314.1B. The governmental entity shall solicit contractors by publishing a notice as provided in section 362.3. A contractor is eligible to perform structure demolition work for the governmental entity after the contractor executes an annual demolition contract in a form satisfactory to the governmental entity, including a bond and insurance. For the twelve-month period following execution of the contract or contracts, the governmental entity may obtain competitive proposals from each eligible contractor as necessary for the demolition of structures. The contractor submitting the lowest responsible proposal shall enter into a contract addendum to perform the work.
