In order to determine the financial responsibility of bidders, the city may require prospective bidders to prequalify as responsible bidders prior to submitting bids on a public construction contract. Notice of any such prequalification requirement shall be made equally and uniformly known to the contractors and the public in the same manner as proposals to award public construction contracts, as set forth in section 3-2-6 of this code. (1985 Code § 7-309)
