WDP performed a comprehensive geotechnical study for this 122,750 square foot flex office building located in a known marine clay environment. An approximate 500 foot long retaining wall, ranging in height from two (2) to twenty-three (23) feet in height, was constructed. In addition, a proposed 2:1 slope on the south end of the project required the installation of forty (40) foot caissons for stabilization due to a buried marine clay seam. WDP then also provided the required Special Inspections for the tilt-wall office building.
