6 PRODUCT MANUFACTURING QUALITY ASSURANCE: PHASE I 6.1 No EPS blocks shall be shipped to the project site until such time as all parts of Phase I MQA have been completed in the order listed and as specified in this section. 6.2 The contractor shall first indicate in writing to the owner's agent whether the molder has a third-party certification program in force.

No approved third-party certification: • For each truckload, each block for the first load and at least one block per load for subsequent truckloads should be tested to ensure that the minimum block dry density, as well as the physical tolerances, meet specifications. • If the selected block meets specifications with respect to its size and shape, and the mass agrees with the mass marked on the block, no further checking of the load for these parameters is required and the shipment is approved conditionally until the Phase IIc test results verify that the block meets specifications.

6.5 If required by the contract documents, the contractor shall submit shop drawings indicating the proposed location and layout of all EPS blocks to be placed during the project. When there are multiple molders, the areas to be covered by each molder shall be clearly identified.

The owner's agent will make every reasonable effort to conduct the laboratory testing expeditiously. However, if unsatisfactory test results are obtained, the contractor may be directed to remove potentially defective EPS blocks and replace them with blocks of acceptable quality at no additional expense to the owner.
