Geotechnical Services for Olympic Well Field Restoration and Arcadia Water Treatment Plant Expansion (2020-2021)
The project involved water treatment plant upgrades at Arcadia Water Treatment Plant, located in the City of Santa Monica. The modifications and upgrades included an extension to the existing RO Building, a new chemical storage area on the east side of the facility, a Booster Pump Station, a UV/GAC/AOP treatment area covered by a canopy structure; and concrete pavement. The new facilities were constructed on slab-on-grade and/or mat-type foundations, and a ten-foot-deep sump was also constructed.
GAI, as a subconsultant to Brown and Caldwell, provided a geotechnical engineering investigation for the design and construction of the project, which included performing site reconnaissance, performing an exploratory field boring program, collecting bulk and relatively undisturbed samples at regular intervals of depth and changes in the subsurface materials; conducting laboratory tests on selected samples; and preparing a final geotechnical report. GAI is currently acting as the geotechnical engineer of the record (GEOR) for the construction phase of the project.
