(Fill placed on all sides <br />of structure is probed with a manual probe rod to confirm uniform compacuve effort); <br />Piping - 1 test per 200 lineal feet (or per backfill/open cut operation) per lift along side of pipe to top -of -pipe, then <br />every 1 foot of fill atop pipe thereafter; <br />Utilities: <br />Sanitary Sewer Pipe -1 test per 200 lineal feet (or per backfill/open cut operation) per hft along side of pipe to top - <br />of -pipe, then every 1 foot of fill atop pipe thereafter; <br />Water Main - 1 test per 200 lineal feet of pipe (or per backfill/open cut operation) per lift from top -of -pipe to <br />finished grade + 1 test per 200 lineal feet for pipe bedding We have assumed a maximum of 3 feet of cover for <br />water main backfill; <br />Misc. Electrical/Plumbing/Irrigation/LT Conduit - 1 test per 200 lineal feet of pipe (or per backfill/open cut <br />operation) per lift from top -of -pipe to finished grade. <br />Concrete/Grout Testing; <br />A minimum of one set of four (4) cylinders will be made for every pour, and for each 50 cubic yards for larger <br />pours; <br />One slump test will be performed for every pour, and for each 50 cubic yards for larger pours, <br />
