3.4 Monitoring and Testing Requirements 0 <br />Earthwork components of the construction are summarized in Paragraph 3.1 of this section. Each <br />component has specific construction requirements that must be monitored. The following sections <br />list monitoring requirements for each type of earthwork. <br />3.4.1 Stockpiling and Soil Management <br />Review Contractor's approved work plan submittal. Verifying stockpile locations, <br />stockpile dimensions, haul routes, material segregation procedures, and erosion, sediment <br />and drainage control measures. Determine and note corrective action items, if applicable. <br />During excavation, hauling, and stockpiling operations continually identify and verify <br />material classifications in accordance with ASTM D2478 and ASTM D2488 as necessary <br />to characterize material stockpile designations. Work closely with Contractor's quality <br />control personnel to classify materials using the rapid field tests described in ASTM <br />D2488. <br />• Verify that stockpiles are constructed with slopes no greater than two horizontal to one <br />vertical and that the top surface maintains a minimum 5 percent grade. Verify slopes and <br />grades using hand held levels and inclinometers, range poles, and measuring tapes. <br />3.4.2 Excavations 0 <br />• Verify that construction staking is performed before work and that survey bench marks <br />with elevations are secured outside the work area. <br />• Verify that excavated materials are segregated into proper stockpiles. <br />• Coordinate with the Earthwork Contractor and Owner to perform excavation verification <br />surveys upon completion of excavating operations. Verify corrective action measures as <br />determined by verification surveys. Verification surveys will also be used to determined <br />limits of excavation for measurements and payment applications. Submit copy of <br />verification surveys to the Construction Manager. <br />3.4.3 General Earthfill <br />• Verify that construction staking is performed before work and that survey bench marks <br />with elevations are secured outside the work area. <br />• Perform visual and manual soil classifications (ASTM D2488) to verify that material <br />source is suitable for earthfills. Verify that the material is free of organic and oversized <br />materials. Perform classifications continually during excavation of borrow materials. <br />Page 19 <br />
