Bunker C Soil Removal
Strider’s work consisted of demolishing and crushing 1,000 tons of concrete foundation and footing type structures and removing approximately 1,200 CY of overburden soil and debris to access contaminated soil strata at the former Georgia Pacific site, immediately adjacent to Whatcom Waterway. 4,800 tons of petroleum contaminated soils were excavated, stockpiled, profiled and transported for offsite disposal at a Subtitle D landfill. Dewatering and water treatment were required for the duration of the excavation, and all water leaving the site was conveyed to an onsite treatment system prior to discharge. Legacy piping systems were documented, cut, capped and removed by Strider crews to facilitate the excavation. 6,300 tons of imported borrow was placed, compacted and graded. A capping system was installed with high visibility separation fabric and 500 tons of permeable ballast. Work was completed ahead of schedule.
