Abstract: Results of a foundation investigation for the Ground Based Radar Project -- Kwajalein Island, Marshall Islands, are presented. Geophysical tests comprised of surface refraction and borehole seismic tests were performed. Results from geotechnical in situ tests, which included standard penetration and plate bearing tests, are also presented to provide a comprehensive report on the foundation materials. The elastic properties, Young's modulus, Poisson's ratio, shear modulus, and cons trained modulus were determined as a function of depth for the foundation soils. These properties are necessary to design a stable foundation that will experience dynamic loading. Foundation materials encountered at this site were coral sands, silts, and gravels to a depth of 60 ft (el -52). The upper 14 ft of foundation soils are a hydraulically placed fill of beach sand. The materials are medium dense to dense sands. A global average SPT N₁ (60) value of 22 is appropriate for the site and correlates to a sand with a relative density of 65 percent.
