This section shall not be construed to prohibit a governmental entity in the award of a contract for a public improvement or a governing body of a city utility from providing, in the award of a contract for a public improvement, an enhancement of payments upon early completion of the public improvement if the availability of the enhancement payments is included in the notice to bidders, the enhancement payments are competitively neutral to potential bidders, the enhancement payments are considered as a separate item in the public hearing on the award of contract, and the total value of the enhancement payments does not exceed ten percent of the value of the contract.2A governmental entity shall not require a potential bidder on a public improvement to provide any information which the potential bidder may deem to be confidential or proprietary as a requirement for being deemed a responsive, responsible bidder. This subsection shall not be construed to prohibit a governmental entity from obtaining information from the lowest responsive bidder to determine the bidder’s responsibility relating to the bidder’s experience, number of employees, and ability to finance the cost of the public improvement. However, a governmental entity shall require nonresident bidders to comply with section 8A.311B, subsection 4.2006 Acts, ch 1017, §9, 42, 43; 2017 Acts, ch 65, §1, 9, 1026.10Opening and considering bids.1The date and time that each bid is received by the governmental entity, together with the name of the person receiving the bid, shall be recorded on the envelope containing the bid.

All bids received after the deadlines for submission of bids as stated in the project specifications shall not be considered and shall be returned to the late bidder unopened. The governmental entity shall open, announce the amount of the bids, and file all proposals received, at the time and place specified in the notice to bidders. The governmental entity may, by resolution, award the contract for the public improvement to the bidder submitting the lowest responsive, responsible bid, determined as provided in section 26.9, or the governmental entity may reject all bids received, fix a new date for receiving bids, and order publication of a new notice to bidders. The governmental entity shall retain the bid security furnished by the successful bidder until the approved contract form has been executed, a bond has been filed by the bidder guaranteeing the performance of the contract, and the contract and bond have been approved by the governmental entity. The provisions of chapter 573, where applicable, apply to contracts awarded under this chapter.2The governmental entity shall promptly return the checks or bidder’s bonds of unsuccessful bidders to the bidders as soon as the successful bidder is determined or within thirty days, whichever is sooner.2006 Acts, ch 1017, §10, 42, 43; 2007 Acts, ch 144, §6; 2022 Acts, ch 1018, §326.11Delegation of authority.When bids are required for any public improvement, the governmental entity may delegate, by motion, resolution, or policy to the city manager, clerk, engineer, or other public officer, as applicable, the duty of receiving and opening bids and announcing the results. The officer shall report the results of the bidding with the officer’s recommendations to the next regular meeting of the governmental entity’s governing body or at a special meeting called for that purpose.2006 Acts, ch 1017, §11, 42, 43; 2007 Acts, ch 144, §726.12When hearing necessary.If the estimated total cost of a public improvement exceeds the competitive bid threshold in section 26.3, or as adjusted in section 314.1B, the governmental entity shall not enter into a contract for the public improvement until the governmental entity has held a public hearing and has approved the proposed plans, specifications, and form of contract, and estimated total cost of the public improvement. Notice of the hearing must be published as provided in section 362.3 and shall include a description of the public improvement and its location. At the hearing, any interested person may appear and file objections to the proposed plans, specifications, contract, or estimated cost of the public improvement. After hearing objections, the governmental entity shall by resolution enter its decision on the plans, specifications, contract, and estimated cost. This section does not apply to the state.2006 Acts, ch 1017, §12, 42, 43; 2016 Acts, ch 1009, §226.13Early release of retained funds.Repealed by 2018 Acts, ch 1097, §6; . See §573.28.26.14Competitive quotations for public improvement contracts.1Competitive quotations shall be required for a public improvement having an estimated total cost that exceeds the applicable threshold amount provided in this section, but is less than the competitive bid threshold established in section 26.3.2Unless the threshold amounts are adjusted pursuant to section 314.1B, the following threshold amounts shall apply:aSixty-seven thousand dollars for a county, including a county hospital.bFifty-one thousand dollars for a city having a population of fifty thousand or more.cFifty-one thousand dollars for a school district having a population of fifty thousand or more.dFifty-one thousand dollars for an aviation authority created within a city having a population of fifty thousand or more.eThirty-six thousand dollars for a city having a population of less than fifty thousand, for a school district having a population of less than fifty thousand, and for any other governmental entity.fThe threshold amount applied to a city applies to a city hospital.3aWhen a competitive quotation is required, the governmental entity shall make a good faith effort to obtain quotations for the work from at least two contractors regularly engaged in such work prior to letting a contract. Good faith effort shall include advising all contractors who have filed with the governmental entity a request for notice of projects. The governmental entity shall provide such notice in a timely manner so that a requesting contractor will have a reasonable opportunity to submit a competitive quotation. Quotations may be obtained from contractors after the governmental entity provides a description of the work to be performed, including the plans and specifications prepared by an architect, landscape architect, or engineer, if required under chapter 542B, 544B, or 544A, and an opportunity to inspect the work site. The contractor shall include in the quotation the price for labor, materials, equipment, and supplies required to perform the work. If the work can be performed by an employee or employees of the governmental entity, the governmental entity may file a quotation for the work to be performed in the same manner as a contractor. If the governmental entity receives no quotations after making a good faith effort to obtain quotations from at least two contractors regularly engaged in such work, the governmental entity may negotiate a contract with a contractor regularly engaged in such work.bThe governmental entity shall designate the time, place, and manner for filing quotations, which may be received by mail, facsimile, or electronic mail. The governmental entity shall award the contract to the contractor submitting the lowest responsive, responsible quotation subject to section 26.9, or the governmental entity may reject all of the quotations. The unconditional acceptance and approval of the lowest responsive, responsible quotation shall constitute the award of a contract. The governmental entity shall record the approved quotation in its meeting minutes. The contractor awarded the contract shall not commence work until the contractor’s performance and payment bond has been approved by the governmental entity. A governmental entity may delegate the authority to award a contract, to execute a contract, to authorize work to proceed under a contract, or to approve the contractor’s performance and payment bond to an officer or employee of the governmental entity. A quotation approved outside a meeting of the governing body of a governmental entity shall be included in the minutes of the next regular or special meeting of the governing body.cIf a public improvement may be performed by an employee of the governmental entity, the amount of estimated sales and fuel tax and the premium cost for the performance and payment bond which a contractor identifies in its quotation shall be deducted from the contractor’s price for determining the lowest responsive, responsible quotation. If no quotations are received to perform the work, or if the governmental entity’s estimated cost to do the work with its employee is less than the lowest responsive, responsible quotation received, the governmental entity may authorize its employee or employees to perform the work.2006 Acts, ch 1017, §14, 42, 43; 2007 Acts, ch 144, §9; 2009 Acts, ch 133, §1026.14AAlternative procedures.1When competitive quotations are required under section 26.14 for a public improvement, the governmental entity may proceed, in lieu of competitive quotations, as if the estimated total cost of the public improvement exceeds the competitive bid threshold under section 26.3.2If the total estimated cost of the public improvement does not warrant either competitive quotations under section 26.14 or competitive bidding under section 26.3, the governmental entity may nevertheless proceed with competitive quotations or competitive bidding for the public improvement.2007 Acts, ch 144, §1026.15Structure demolition project.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.2006 Acts, ch 1017, §15, 42, 4326.16Prequalification requirements prohibited.A governmental entity shall not by ordinance, rule, or any other action relating to contracts for public improvements for which competitive bids are required by this chapter impose any requirement that directly or indirectly restricts potential bidders to any predetermined class of bidders defined by experience on similar projects, size of company, union membership, or any other criteria. However, a governmental entity shall require nonresident bidders to comply with section 8A.311B, subsection 4.2017 Acts, ch 65, §2, 9, 10
