Cal. PCC § 20919.29

For purposes of employment of apprentices on job order contracts, when the individual job order involves more than thirty thousand dollars ($30,000) or 20 working days, all general contractors or subcontractors shall at all times be in compliance with Section 1777.5 of the Labor Code and shall comply with the following:

(a) Prior to commencing work on an individual job order, every contractor shall submit job order award information to an applicable apprenticeship program that can supply apprentices to the site of the job order. The information submitted shall include an estimate of the journeyman hours to be performed under the contract, the number of apprenticeships proposed to be employed, and the approximate dates the apprentices would be employed. A copy of this information shall also be submitted to the awarding agency if requested by the awarding agency.

(b) The ratio of work performed by apprentices to journeymen employed in a particular craft or trade on the job order may be no higher than the ratio stipulated in the apprenticeship standard under which the apprenticeship program operates where the job order contractor agrees to be bound by those standards but, except as otherwise provided in Section 1777.5 of the Labor Code, in no case shall the ratio be less than one hour of apprenticeship work for every five hours of journeyman work.

(c) Every apprentice employed under the job order contract shall be paid the prevailing rate of per diem wages for apprentices in the trade to which he or she is registered and shall be employed only at the work of the craft or trade to which he or she is registered.

(d) Every apprentice employed under the job order contract shall be hired from the local joint labor management apprenticeship committee that has jurisdiction in the geographic area of the project.
