When a determination has been made to allow advance payment for materials, the Project Engineer or a verifier representing either the Central Laboratory, District Materials Engineer or an approved Department representative agency acting on behalf of the Project Engineer shall make an inventory of the pre-tested items to be stored or stockpiled. Upon completion of the inventory, a Certificate of Storage Form, TMD 323 must be completed and distributed by the Department representative in time for an advance payment to be included on the applicable monthly estimate. The TMD 323 Form lists the inventoried items from the Contractor's storage or stockpile area.
