All work shall be in accordance with this proposal and any further <br /> direction from BCI ENGINEERS & SCIENTISTS,the engineer of record. <br /> Our objective with this work is to remediate the effects of the sinkhole activity beneath this structure. Several <br /> remedial measures have been discussed in the referenced report; 1) Deep Subsurface Grouting will deal <br /> with the sinkhole grouting treatment as outlined in the attached plan. 2) Shallow Chemical Grouting is <br /> intended to help consolidate the shallow loose sandy soils around the perimeter of the buzlding. <br /> l�l�.l:SSiJI�I: t�l�.()iJ'1'Ii�T(� <br /> T'his Deep "Compaction" type grouting approach will attempt to "Seal Off' the top surface of the <br /> limestone and fill solutioning channels in the overburden soils. Based on the information provided, we <br /> expect the Grout Injection points to extend down to an estimated depth of 55' below grade. . <br /> Drilling equipment will install nominal3-inch diameter flush joint steel casing around at locations approved <br /> by the engineer. After the casing has been installed to the prescribed depth a specially designed grout pump <br /> (Capable of generating 950 psi & 45 Cubic Yards per hour) will inject grout through a continuous length of <br /> hosing to the particular grout injection locations. The injection of the grout will be controlled by both volume <br /> and pressure while the steel grout pipe is extracted on a semi-continuous basis. Visual monitoring points will <br /> be maintained as specified. � <br /> Approximately 32 Injection Points will be required to inject an estimated 350 cubic yards of grout material. <br /> Injection points shall be angle drilled on an alternating basis or as otherwise directed by the engineer. Any <br /> additional injection points required would be installed at the unit rates provided in the pricing section of this <br /> proposal. <br /> Initials� <br /> Foundation Solutions Since zg89 <br /> Sinkhole Remediation I Pressure Grouting I Underpinning I Chemical Grouting I Pre-Construction Piling www.cfi-i.com <br /> Florida State General Contractor's License CGCiso4o67 <br />
