Earth Systems reviewed prior geotechnical studies, performed geologic seismic studies and performed geotechnical consulting services for upgrades and improvements at two elementary schools. The scope included evaluation and identification of the geologic/seismic conditions and potential hazards associated with the proposed additions to the sites. Earth Systems prepared a geotechnical feasibility study which provided the input needed for grading, site development and foundation design for both sites. The Earth Systems team also provided materials testing and special inspections during the construction phase of the project.
