The EPA’s Mid-Continent Ecology Division conducts innovative research and predictive modeling to document and forecast the effects of pollutants on the integrity of watersheds and freshwater ecosystems. Our team performed phased renovations of seven labs that included a clean room, biology lab, fish sample prep lab, a wet lab, and an organic chemistry lab. These projects required complicated MEP upgrades and close coordination of schedule, as the facility was in operation throughout all seven phases. The owner moved out of one lab to allow time for renovation, then moved back into the newly renovated space. This method guaranteed a smooth transition and schedule compliance. Close collaboration and communication with the client was crucial to the success of these transitions.
