The work <br /> consists of furnishing all labor, equipment and materials required to inject cementitious grout to an i <br />� estimated average depth of 65 feet.Do not drill beyond 80 feet unless prior permission is obtained <br /> by the Engineer of Record. The stabiliza�ion program is intended to stabilize possible unstable <br /> subsurface soils by compacting any loose soils via densification,where present, sealing the <br /> limestone surface,voids and any partially in-filled cavities, and to minimize the potential for future <br /> ground subsidence due to raveling activity. " <br /> 2.0 SCOPE <br /> The scope of the stabilization program includes vertical and/or angled grout injections. The total � <br /> estimated grout quantity,injection pipe footage and grout point locations are attached. However, ! <br /> the grouting program may be modified by the Contractor and Geotechnical Engineer(or his or her � <br /> representative) as dictated by the actual field co�ditions. In these specifications,"Geotechnical <br /> Engineer"refers to Geohazards,Inc.'s geotechnical engineer. i <br /> If directed by the Geotechnical Engineer or his or her representative, additional grout locations may � <br /> be required based on the site conditions encountered. Injection point locations are planned around � <br /> the perimeter of the structure on 8 - 10 foot centers. Alternative grout locations may be required. ; <br /> However,the Contractor or Geotechnical Engineer(or his or her representative)will establish the <br /> fmal grout injection locations in the f eld. <br /> 3.0 CONTRACTOR � <br /> The pressure grouting Contractor sha11 submit his or her qualifications to the Geotechnical <br /> Engineer. The Contractor shall have at least three years of experience in cement pressure grouting <br /> jobs,and shall submit references of his or her activities if requested. i. <br /> i <br /> I <br /> i <br /> i <br /> (352)371-7243 (800)770-9990 Fax: (3�2)371-4410 ' <br /> wwtiv.sinkholes.com adminCa�sinkholes.com <br />
