White Shield conducted a geotechnical investigation for a 20,000 SF Washington State Penitentiary (WSP), New Program and Support Services Building. The investigation included constructing 4 geotechnical borings, 3 each earth probe borings, soil classification, soil testing, and measurement of groundwater elevations. Our design recommendations include the allowable soil bearing pressures, cut and fill recommendations, sub-grade preparation, and seismic design information along with a site grading plan.
