- Excavation of 14,000 tons of contaminated non-hazardous material
- Excavation of 1,300 tons of hazardous material
- Demolition of exciting building
- Backfill material
This project was the remediation of a 14-acre site located in Hicksville, NY. Posillico excavated +/- 14,000 tons of contaminated non-hazardous polychlorinated biphenyls (PCB) soil and 1,300 tons of hazardous PCBs. Scopes included the demolishing of an existing building on site, excavating and backfilling a 1’ thick cap that was placed over entire site. The cap consisted of 8” backfill material (bank-run) and 4” topsoil.
WHAT MADE THIS JOB COMPLEX
The biggest challenge was the large open area that was partially remediated causing it to be a safety concern due to the holes around the site. In addition, the presence of 1,300 tons of hazardous materials presented a serious issue for treatment, impacting the community and construction team, requiring the development and integration of stringent protocols.
HOW POSILLICO SOLVED IT
Posillico worked around the previously excavated site with due caution to ensure no accidents or injuries occurred. In addition, proper PPE was supplied, and the team expertly delineated all contaminated areas on site. All materials were excavated and disposed of using certified HAZWOPER OSHA workers. Lastly, the team also worked closely with the engineer which facilitated efficient collaboration towards the common purpose of performing the scope.
