For the modernization and expansion of one junior high school and two elementary schools, Earth Systems reviewed prior geotechnical studies and provided geotechnical consulting services and implemented a subsurface exploration program to evaluate geotechnical characteristics for the subsurface soils. The analysis generated a site-specific seismic response spectra which helped determine the liquefaction potential, the vertical and horizontal load bearing capacities of the foundation, and the total and differential settlement. The study concluded that the site was suitable for development.
Earth Systems also provided materials testing and special inspections during the construction phase of the project.
