As this industrial manufacturing client wrestled with the discovery of PCBs in paint at active plants in multiple states, GZA was asked to develop a comprehensive abatement and remediation program that minimized disruption to ongoing plant activities and was protective of workers, the environment, and the neighbors. Spread across three states, the projects were subject to a diverse set of local, state, regional, and federal regulatory drivers, including two separate regions of the U.S. Environmental Protection Agency (USEPA).


GZA evaluated each site and tailored its solution to each location, meeting all regulatory, logistical and health and safety requirements. GZA applied a construction management (CM) approach to the project, which included writing performance-based specifications, hiring and managing contractors, and engineering robust abatement, containment, and monitoring systems.

Key to the success of the project was GZA’s proactive project sequencing, which accommodated ongoing plant operations, anticipated and resolved community concerns, and addressed challenging technical conditions, including working in active rail lines as well as scaling multiple silos up to 110’ feet tall.


GZA helped the client achieve compliance at all three sites, with limited regulatory agency involvement. The projects were completed on-time and on-budget, with virtually no disruption to plant operations, plant employees, or the surrounding community.
