State bid laws require that cities and villages advertise for bids by publishing a class 2 notice under Wisconsin Statutes Chapter 985. Wis. Stats. secs. 61.54 and Sec. 62.15(3). A class 2 notice requires two insertions or publications of the notice occurring one week apart. The last notice must be published at least one week before the bid opening. Wis. Stat. Sec. 985.01(1). It should be noted that this is a minimum requirement and cities may advertise in as many publications and as many times above the minimum as they see fit.
