The Challenge
A global intelligent power management company was expanding a facility and needed to remove existing concrete in the reactor room and surrounding areas to prepare for new construction. Long-standing equipment had leaked oil containing polychlorinated biphenyls (PCBs), contaminating the concrete slab. Because PCBs are highly regulated due to their environmental and health risks, the company first needed to determine the extent of the contamination and properly manage all impacted materials before work could continue. While the original plan was to remove the concrete based on test results, the project quickly evolved when the company decided to remove the entire slab. This expanded the scope and increased the urgency, requiring quick coordination while maintaining compliance and keeping the overall construction schedule on track.
The Solution
Envita Solutions partnered with multiple suppliers to carry out a comprehensive testing, excavation, and disposal strategy. Concrete core samples were collected from several areas using specialized coring equipment and analyzed to determine the presence and depth of PCB contamination. The results showed that while some contamination was limited to the surface, other areas had deeper penetration within the slab.
After the concrete was removed, Envita conducted soil sampling beneath the slab to evaluate whether contamination had migrated into the underlying soil. When low-level PCB impacts were found, the project scope shifted again to include a targeted excavation and removal of the affected soil. Despite changing requirements and tight timelines, the team quickly coordinated equipment, transportation, and disposal solutions to manage the regulated PCB waste streams. Additional verification sampling confirmed that all contaminated material had been successfully removed, and that the site met environmental standards, allowing construction to proceed.
The Result
By partnering with Envita, the global intelligent power management company was able to remove 150 tons of PCB-impacted soil and concrete, safely dispose of all contaminated materials, and preserve their timeline, despite scope changes.
