Cal. Educ. Code § 17250.66 — Alternative Design-Build Contracts

(a) If the school district elects to award a project pursuant to this chapter, retention proceeds withheld by the school district from the design-build entity shall not exceed 5 percent.

(b) In a contract between the design-build entity and a subcontractor, and in a contract between a subcontractor and any subcontractor thereunder, the percentage of the retention proceeds withheld may not exceed the percentage specified in the contract between the school district agency and the design-build entity. If the design-build entity provides written notice to any subcontractor that is not a member of the design-build entity, before or at the time the bid is requested, that a bond may be required and the subcontractor subsequently is unable or refuses to furnish a bond to the design-build entity, then the design-build entity may withhold retention proceeds in excess of the percentage specified in the contract between the school district and the design-build entity from any payment made by the design-build entity to the subcontractor.
