recommendations, and to allow design changes in the event that subsurface conditions diller <br />from those anticipated. <br />Geotechnical observation/testing can be performed at the following stages: <br />. During ANY grading operations, including excavation. removal. filling and backfilling. <br />etc.. After excavation for building footings to verify the adequacy ofunderlying materials.. After pre-saturation ofslab subgrade earth materials, ifany, prior to pouring concrete.. During backfill ofdrainage and utility line trenches, ifany, to verify proper compaction <br />and materials used.r After compaction ofsubgrade soils and aggregate base for new driveway. ifany.. When/lfany unusual geotechnical conditions are encountered. <br />Note: ll'Gcotechnical lntcrnational is not provided the opportunity to perfbrm t he geotec lr rr ica I <br />observation/testing during the construction phase. Ceotechnical lntemational will take no <br />responsibility for the conclusions and recommendations contained in our report in the event that <br />subsurface conditions dilfer from those interpreted and anticipated during our preliminary <br />investigation phase prior to the start ofconstruction. <br />Page 9
