EGC provided hazardous materials consulting associated with the renovation of a sprawling 210,000 square foot high school building built in 1960 and 1968 on a former airport site. Initial work included a Phase I Environmental Site Assessment (ESA), followed by various Phase II site assessment activities, a pre-renovation hazardous materials assessment, PCB analysis and chlorine-based screening of select building materials, and the removal and clean-up of a leaking gasoline underground storage tank. Results of the initial assessments and screenings were incorporated into multiple design packages for the Temp Work, Phase 1, Phase 3A & 3B, and Phase 4 renovation and demolition work. Our services included construction monitoring and dust monitoring during the removal of asbestos, PCBs in building materials, lead-based paint, and miscellaneous hazardous materials.
