2.6 PRODUCTION QUALITY CONTROL

2.6.1 Visual Inspections

Perform random daily checks, by the SMC Inspector(s), of all stone produced at the quarry for size, gradation, elongation, cracks, deterioration and other defects visible to the naked eye on the entire surface area of the stone, on 100% of armor stone. Check 100% of underlayer for stone quality, and 20% measured for compliance with gradation and elongation requirements. Include in the random daily checks comparing the material being produced to that which exists in the pre-production demonstration stockpile. Initiate corrective action, by the SMC Supervisor, if any significant reduction in overall stone quality, gradation mix, or required sizes is observed to be occurring. Each day, wet and reinspect for minute cracks, five or more of the largest stones with the lowest potentially acceptable quality, to determine if additional inspections are necessary on all stone. Mark stones with cracks or defects that are detrimental to a long lasting product or that are otherwise unsatisfactory for the work, with a reject symbol and are not permitted to be shipped to the project site.

2.6.2 Project Site Inspection and Tests

At the project site, perform random visual inspections (by an SMC Inspector) of all materials, for size, gradation, elongation, fractures, deterioration and other defects to assure that handling during loading, transporting, unloading and placement has caused damage to the materials and to assure they are placed in accordance with the requirements of this Section. Perform weighing of stones or remeasuring them to verify computed
