This project was a phased remodel of United States Environmental Protection Agency (EPA) Central Regional Laboratory in the Clark Street Federal Building. We were brought in to plan, design and oversee construction of Phase Three (organic chemistry labs) and Phase Four (inorganic chemistry labs). The project included asbestos and lead paint abatement and abatement of a perchloric acid hood and the replacement of 21 fume hoods and 8 canopy hoods in Phase Three, and 10 fume hoods and 8 canopy hoods in Phase Four.
