Except as otherwise provided in this chapter, purchases of supplies, equipment and services over $10,000 shall be by written contract and/or approved purchase order with lowest responsible bidder, pursuant to the procedure prescribed in this chapter.
A. Notices Inviting Bids. Notices inviting bids shall be advertised by the purchasing officer or designee and shall include a description and specifications of the articles to be purchased, delivery, conditions and discounts, shall state where bid documents and specifications may be secured, the cost of a document and specifications, if applicable, and the time and place for filing and opening bids.
1. Public Filing and Notice. Notices inviting bids shall be published twice in an adjudicated newspaper of general circulation 10 days before the date of opening of bids, or when there is no adjudicated newspaper for the city, notices may be posted for 10 days in at least three public places designated for posting public notices in the city;
2. Bidders' List. The purchasing officer shall solicit sealed bids from all responsible prospective suppliers whose names are on the bidders' list or who have made written request that their names be added thereto. Failure to do so, however, shall not invalidate the purchase.
B. Bidders' Security. When deemed necessary by the purchasing officer, bidders' security may be prescribed in the public notices inviting bids. Bidders shall be entitled to the return of bid security; provided, however, a successful bidder shall forfeit the bid security upon refusal or failure to execute the contract within 10 days after the preparation and mailing of the contract unless the city is responsible for the delay. The city council may, on the refusal or failure of the successful bidder to execute the contract, award it to the next lowest responsible bidder. In such event, if the city council awards the contract to the next lowest bidder, the amount of the lowest bidders' security shall be applied by the city to the contract price differential between the lowest bid and the second lowest bid and the surplus, if any, shall be returned to the lowest bidder.
C. Bid Opening Procedure. Sealed bids shall be submitted to the city and shall be identified as "Bid," with the project name on the envelope. Bids shall be opened in public at the time and place stated in the public notices or as soon thereafter as possible. Bids received after the deadline established in the notice inviting bids shall be returned to the bidder unopened.
D. Rejection of Bids. At its discretion, the city council may waive any irregularity, reject any and all bids presented, and re-notice for bids pursuant to the procedure prescribed in this section.
E. Award of Contracts and Purchase Orders. Except as otherwise provided in this chapter, contracts and purchase orders shall be awarded to the lowest responsible bidder.
F. Tie Bids. If two or more bids received are for the same total amount or unit price, quality and service being equal, and if the public interest will not permit the delay of readvertising for bids, the city council may in its discretion accept the one it chooses or accept the lowest bid made by and after negotiation with the tie bidders.
G. Performance Bonds. The purchasing officer shall have the authority to require a bond or bonds before entering into a contract in such amounts as he or she shall find reasonably necessary to protect the best interests of the city. If the purchasing officer requires such a bond or bonds, the form and amount of the bond shall be described in the notice inviting bids.
H. No Responsive Bids. When no responsive bids are received, the purchasing officer is authorized to negotiate with prospective vendors for written proposals. The council may consider such proposals, and award the contract or purchase order, if at all, to the lowest responsible bidder.
