Cal. Public Contract Code § 10161

The department may also require from prospective bidders the completion, under penalty of perjury, of a standard form of questionnaire concerning the past safety record of each prospective bidder, any officer of such bidder, and any managing employee of such bidder. The department may refuse to prequalify any prospective bidder who fails to submit a completed questionnaire when required, or for the reason that the information contained in the submitted questionnaire or otherwise known to the department indicates a continuing unsatisfactory safety record. The director of the department shall prescribe guidelines listing criteria which will be utilized administratively in determining an unsatisfactory safety record. A refusal by the department to prequalify a prospective bidder shall be issued only after the department has granted such bidder a hearing. This section shall in no way abridge or restrict the right of the department to later determine whether the low bidder on a particular project is the lowest responsible bidder for purposes of award of the contract, including the holding of hearings thereon. The Director of Industrial Relations shall approve the standard form of questionnaire and the guidelines listing criteria which will be utilized administratively by the department in determining an unsatisfactory safety record prior to their use by the department.
