Cal. Educ. Code § 17250.20

Upon making a determination by a school district governing board that it is in the best interest of the school district, the governing board may enter into a design-build contract for both the design and construction of a school facility if that expenditure exceeds two million five hundred thousand dollars ($2,500,000) if, after evaluation of the traditional design, bid, and build process of school construction and of the design-build process in a public meeting, the governing board makes written findings that use of the design-build process on the specific project under consideration will accomplish one of the following objectives: reduce comparable project costs, expedite the project’s completion, or provide features not achievable through the traditional design-bid-build method. The governing board also shall review the guidelines developed pursuant to Section 17250.40 and shall adopt a resolution approving the use of a design-build contract pursuant to this chapter prior to entering into a design-build contract.
