Burns & McDonnell was the designer of record for this design-build medical training and laboratory facility, Medical Instruction Facilities 3 and 4 on the nine-building Medical Education & Training Campus (METC). METC is the largest consolidated medical training center nationwide serving all branches of the U.S. military. From here, medics, corpsmen and technologists train before deploying globally. These LEED Gold-certified facilities total 420,000 square feet and are the largest buildings on the METC site. Laboratory space totals 98,000 square feet and includes audiology, radiology, hematology, microbiology, chemistry, industrial hygiene, entomology and histopathology. Training and instructional facilities include specialized classrooms, BSL-2 laboratories, and simulated hospital facilities such as a surgical suite and examination rooms. A white roof, energy-efficient lighting and demand-controlled ventilation contribute to a 30 percent reduction in energy use. Low-emission paints, carpets and adhesives ensure healthy indoor air quality. In addition, the design isolates potential hazards from labs, medical waste rooms and gas storage areas. Xeriscaping and low-flow plumbing reduce potable water use by nearly 45 percent.
