This subsection shall not prevent the commission from having any work done by its own employees, nor shall it apply to repairs, or to the furnishing of materials, supplies or labor, or the hiring of equipment or vehicles, when the safety or protection of its or other public property or the public convenience requires, or the exigency of the commission's service will not admit of such advertisement. In such case the commission shall, by resolution, passed by the affirmative vote of a majority of its members, declare the exigency or emergency to exist, and set forth in the resolution the nature thereof and the approximate amount to be so expended.
Thereupon the commission shall designate the time when it will meet at its usual place of meeting to receive proposals in writing for doing the work or furnishing the materials in accordance with, and upon the terms and conditions of, such form of contract or alternative contracts, and shall order its clerk to give notice, by advertisement inserted at least 10 days before the time of such meeting in at least two newspapers printed and circulating in the county or counties in which the municipalities in said water supply project are situated, of the work to be done and the materials to be furnished, particular plans and specifications of which shall, at the time of such order, be filed in the office of the commission.
All proposals shall be publicly opened by the commission, which shall award the contract to the lowest responsible and qualified bidder under the form of the contract originally adopted or the form of the alternative contract which shall then be adopted by it as most advantageous.
Each contractor shall be required to give bond satisfactory in amount and security to the commission for the faithful performance of his contract.
