(2001a),<br>SHRP2 Phase I Technology Assessment (2008)</em></p><p><strong>Method Summary</strong></p><p>In this method material components are examined at the casting yard (for systems with precast elements) and on-site. The visual inspection should be performed on prefabricated materials. When delivered to the project site, the inspector should carefully inspect all material (precast facing elements, reinforcing elements, bearing pads, facing joint materials, and reinforced backfill).</p><p><strong>Accuracy and Precision </strong></p><p>The inspection procedures and plans and used specifications are reviewed based on authorized QA/QC parties, and more detailed description can be referred to the mentioned documents. This procedure is extremely important to reduce any potential problems and construction failures.</p><p><strong>Adequacy of Coverage </strong></p><p>The inspections of all the involved construction elements include reinforcing elements, facing elements, facing joint materials, and properties of in-situ soil and backfill materials should be performed depending on the specific requirements or constrains. Through performing these inspections, the accuracy and precision of the construction can be ensured.</p><p><strong>Implementation Requirements </strong></p><p>It is the contractor or owners’ responsibility to make sure all the inspection steps that are included in specifications should be complete.</p><p><strong>General Comments </strong></p><p>Construction materials inspections are benefit to select the proper materials based on structures and local information, and establish the creditability and the contractors by minimizing the potential errors.</p></p>
