It is possible that there are soil and water conditions on <br /> site that were not represented by the borings. Consequently, on-site observation during <br /> construction is considered integral to the successful implementation of the <br /> recommendations. We believe that qualified field personnel need to be on site at the <br /> times outlined below to observe the site conditions and effectiveness of the <br /> construction. <br /> We recommend that the completed excavation and prepared subgrade be observed <br /> and tested by a soils engineer/technician prior to fill placement or construction of any <br /> foundation elements. These observations would be necessary to judge if all unsuitable <br /> materials have been removed from within the planned construction area and that an <br /> appropriate degree of lateral oversize has been provided for in those areas where fill will <br /> be placed below the bottom of foundation grade. <br /> We recommend a representative number of field density tests be taken in all engineered <br /> fill placed to aid in judging its suitability. We suggest that at least one density test be <br /> performed for at least every 2500 square feet of engineered fill placed for every 2' of fill <br /> depth. Additional tests should be taken where confined areas are compacted. Any <br /> proposed fill material should be submitted to the laboratory for tests to check <br /> compliance with our recommendations and project specifications. <br /> Stork Twin City Testing Corporation is an operating united of Stork Materials Technology B.V., <br /> twin citv testinq Amsterdam,The Netherlands,which is a member of the Stork group <br /> ��«�,�, <br />
