Based on <br /> the WOH�WOR/LOC zones identified in the SPT borings, sinlchole activity is considered to be <br /> a contributi.ng source of distress. Subsurface compaction grouting, a common ground <br /> modification technique, is indicated to mitigate raveling and fill void spaces adjacent to and i <br /> below the structure. <br /> The following is a basic plan, including estimated quantities, to remediate the sinkhole I <br /> conditions. � <br /> Task Description Estim Su Quantity i <br /> rv y <br /> 1 Mobilization/Demobilization 1 ea. � <br /> Pernuts � <br /> 2 Site Preparation 1 ea. <br /> � <br /> Injection Pipe Installation; I <br /> 36 total grout points, 2,3401f.total <br /> 3 South half of the Building-18 points, Soutlt ltalf of tlte building <br /> to competent Iimestone estimated 1,170 lf <br /> approximately 65 ft.below the surface � <br /> i <br /> 250-350 cy.total <br /> 4 Grout Injection ,S"outli half of tlze builcling � <br /> � 125-175 cy. � <br /> I <br /> 5 Monitoring/Certification 1 ea. <br /> � <br /> � <br /> (352)371-7243 (800)770-9990 Fax:(352)371-4410 � <br /> www.sinkholes.com adminCa,sinkholes.com <br />
