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 laboratories renovated during this project are used to test environmental samples and monitor conditions in the Great Lakes Region. Region Five includes: Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin. The laboratories being renovated were built in the mid 1970’s and were relatively unchanged prior to this renovation. The design underwent significant evolution due to after further input from researchers, development of the budget and inclusion of improved lab planning strategies.
