The masture conteM of fill is very importaM and must be cbaely controlled during the <br /> filfing and compaction process. <br /> The allowable thickness of the flll lift wiil depend on the material type selected, tha compadion <br /> equipment used, and the number of passes made to compad the INt. The laoee fift thidmess <br /> should not exceed 12 i�iches. We recommend testing the flll as it is pleced. If tFie fill is not <br /> su�aentry compaded, it can be recompacted before another IMt is placed. This eliminates the <br /> need to remove the 811 to achieve fhe required compection.

If <br /> the subsurface conditions encouMered during conatruction are signiflpntiy diftererrt from thoee <br /> observed in aur expiorations, we should be advised at once ao that we qn review these conditions <br /> and reconsider our recommendations where necessary. UnaMiapeted aoil cor�ditiona are <br /> commonly encaumered on constructlon sltes antl pnnot be fully anticipated by merely takfny soil <br /> samples in test pits. Subsurface conditione can also vary batween expbration Ixatiorts. Such <br /> unexpected cond'Rions frequerdly require making additlonal expendftures to attain a properly <br /> constructed projed. It is recommended that the oMmer conaider providing a contingency fund to <br /> accommodate such potendal extra costs and risks. This Is a standard recommendatlon for all <br /> projects. <br /> This report has been prepared far the exclusive use of Legacy Development and its represeMatives <br /> for speciflc applicatlon to this proJect and site.
