Northwest Demolition was contracted for the demolition of a 22,500 square-foot concrete and steel-framed warehouse structure.  The building was used for the decommissioning of transporters and storage of capacitors and ballasts containing polychlorinated biphenyls (PCBs).  The building debris was classified as having low-level PCB contamination, as well as asbestos-containing material and other regulated building materials.  As such, all demolition debris was to be handled as TSCA regulated waste.  The few clean sections of floor slab and foundation were separated from the remaining structure and recycled.  As a part of site clean up efforts, Northwest Demolition also excavated the PCB-impacted soil from beneath the building slabs.

This project demonstrates Northwest Demolition’s familiarity with regulated waste streams, as well as our ability to effectively manage and tackle environmentally sensitive projects.
