The city shall have the power to reject any or all bids, to determine and to waive any irregularities or informalities that do not materially affect the substance of the bid itself, and to make further calls for bids in the same manner as the original call; or, if in its judgment the project can be done by the city at less cost than the lowest bid submitted, it may do so without making further call for bids or awarding any contract therefor. If no bid is received on the first call, the city may re-advertise and make a second call, or may enter into a contract by negotiation without further calls, or may purchase the supplies, material or equipment and perform such work or improvement with in-house forces. (Ord. 6765 § 1 (Exh. A), 2020; Ord. 6545 § 1, 2014.)
