A. Where a public project is to be performed which is subject to the provisions of this ordinance, a notice inviting informal bids shall be
mailed to all contractors for the category of work to be bid, as shown on the list developed in accordance with § 3.16.110, and to all construction trade journals as specified by the California Uniform Construction Cost Accounting Commission in accordance with Section 22036 of the Public Contract Code.
B. Additional contractors and/or construction trade journals may be noticed at the discretion of the department soliciting bids; provided, however:
1. If there is no list of qualified contractors maintained by the city for the particular category of work to be performed, the notice inviting bids shall be sent only to the construction trade journals specified by the Commission.
2. If the product or service is proprietary in nature such that it can be obtained only from a certain contractor or contractors, the notice inviting informal bids may be sent exclusively to such contractor or contractors.
