This document is a geotechnical investigation report prepared by Geo-Systems Design & Testing, Inc. for Clarendon County, South Carolina, regarding the proposed Turbeville Fire Station located on US 378 in Turbeville. The report details a comprehensive subsurface exploration and analysis of the site, which encompasses approximately one acre. The investigation involved conducting five soil test borings to depths ranging from 15 to 40 feet, with the primary objectives of evaluating site materials, assessing material performance during construction, and providing recommendations for foundation loading, building subgrade elevations, and pavement design.

The soil investigation revealed that the site consists primarily of Fuquay Fine Sand and Lynchburg Loamy Sand with varying soil strata, including layers of fine sand, sandy clay loam, and silty clay. Groundwater was observed at depths between 3-6 feet during the borings. The report includes critical recommendations for site preparation, foundation design, and construction considerations, such as compacting subgrade soils to 98% of the standard Proctor density, ensuring proper drainage, and addressing potential challenges with soil consistency and load-bearing capacities. Seismic evaluations indicated the site is not susceptible to liquefaction or ground rupture, and the soils are deemed suitable for structural backfill with proper moisture conditioning.
