SOIL REMEDIATION PROJECT & CLOSURE THROUGH LAFD

Cornerstone was contracted to assess levels of subsurface soil contamination. Cornerstone delineated contaminated soils by taking series of boring samples for laboratory analyses of contaminant concentrations.

Cornerstone excavated the area and removed a total of 203.85 tons of contaminated soils with hazardous levels of nickel and chromium.

After the soil was stabilized and the samples met the clean-up goals, Cornerstone backfilled the site with clean imported soil, re-compacted the soil, and resurfaced with concrete to match existing.

DEMOLITION OVER WATER OF PIER & PILINGS UNDER ARMY CORPS OF ENGINEERS

Cornerstone provided services to demolish and remove the old creosote and arsenic saturated pier, located within an environmentally sensitive area of the Los Angeles World Port.

This project required presenting a detailed engineering plan to the US Army Corps of Engineers, the World Port, Fish and Game, RWQCB, and Terminal Island Local Authorities.

The project included permitting, concise water protection planning, pollution migration, mitigation actions along with reporting to all multiple agencies involved.

Cornerstone saved Heinz International approximately 40 percent of the overall project costs by combining services of both engineering and environmental management divisions.
