The DBB Guide Schedule tables apply to all design-bid-build contracts. The minimum acceptable project test frequency is shown in these tables as a guide. Perform additional testing as necessary.

Unless otherwise specified in the contract, testing is conducted by the Department or independent laboratories employed by the Department. When specified by the contract, Contractor-performed QC sampling and testing may be used as part of the acceptance decision when verified by the department. In all other cases, Contractor testing is for information only and is conducted at the Contractor’s expense.
