Ouriny construction, �11 surfue w�ter should be <br /> tntercepted �nd directed iw�y from exc�v�tions md fills. Temporary <br /> sw�les �nd/or su�ps may be reQutred to control runoff �s constructian <br /> proyresses. B�sed on the fi�ld lnvestiy�tton� qroundw�ter inflow should <br /> be �nticip�ted, however the �mount of yroundw�ter will prob�bly viry <br /> se�sonally. All w�ter should b� dlrected �w�y from the crests of slopes <br /> and should be prevented fro� �ccunul�ting ne�r the toes of slopes. <br /> � DuH ng persistent wet we�ther construcN on, �11 cut slopes s�ould be <br /> ; protecteA with pl�sttc sheetino. <br /> The dr�inage contral provisions should ensure thit groundwater and <br /> surfue w�ter does not accumul�te �d��cent to floor slabs or foundation <br /> w�lls. Me recommend interlor floor sl�bs �nd other bclow gr�de <br /> structur�l elements be provlded with subdr�ins which discharge by <br /> tightline to a suit�ble outlat. Roof le�ders should be directed away <br /> fro� the structures in a sep�r�te tightlin• system. <br /> 6. USE OF THIS REPORT <br /> This report has Deen prep�red exclusively for the use af Centron �nd <br /> their consultants for speciflc �ppliution to thfs pro�ect. The <br /> tnvestig�tion h�s been performed in �ccord�nce wlth generally accepted <br /> loul yeotechntc�l en inee►•inq pru t1c�s to provide geotechntc�l <br /> informatton to �llow �in�liz�tion of the s1t� pl�nning. Once the <br /> proposed site deveiopment is fin�lized or should pl�ns be different from <br /> thos� described, we should be cant�cted to review our conclusions �nd <br /> recommend�tions. <br /> TAere are posslble v�rtat'ons in subsurfue condltions between the <br /> explorations md in the grour�dw�ter conditions with time. We recommend <br /> � contingency for unmticip�ted conditions be included 1n the . <br /> � censtructlon schedule and budget. Further, we recommend we be retained <br /> to perform monitorinq �nd testtny during canstruction to confirm the <br /> conditions lndtc�ted by thE� explorations md/or provide corrective <br /> recommenE�tlons �d�pted to �.he conditions reve�led during the work. <br /> I <br /> Golder A�soclat�a <br />
