C3M provided electrical and communications systems in conjunction with Clark’s effort to design and construct the MD 355 Crossing in Bethesda, Maryland. The crossing is comprised of a new below-grade pedestrian tunnel under Rockville Pike (MD 355), connecting the National Institutes of Health campus with the Walter Reed National Military Medical Center campus. The team constructed a 49-foot-diameter, 128-foot-deep shaft with a 30-foot-long connector tunnel into the existing Medical Center Metro. The shaft contains a new elevator system, allowing passengers to access the Metro from the Walter Reed campus. C3M’s electrical scope of work included power and lighting systems and communications systems work included fire alarm, access control, intrusion detection, CCTV, telephone, public address, SCADA, and radio systems.
