Madigan Army Medical Center

USACE - Little Rock DistrictJoint Base Lewis-McChord

Madigan Army Medical Center is one of the largest Army hospitals in the world. The design team was tasked with replacing the emergency side electrical gear for the facility, including generators, electrical equipment, and transfer switches. It was critical that the facility remained fully operational during design and construction.

CMTA designed enhanced due diligence, which included metering all 32 transfer switches and a complete facility arc flash study. The project also required the relocation of the existing 40,000-gallon underground fuel storage tanks to facilitate future planned expansion. CMTA designed a new fuel delivery and storage system that offered 14 days of on-site storage. The most critical component of this project is the construction sequencing that allows the facility to stay operational.

The team designed a small bump-out addition to house the new generators so the existing generators could stay operational. Once the new generators are active, the old generators can be decommissioned, thus freeing up critical square footage within the existing facility to accommodate the new emergency gear. This leapfrog approach allows the facility to remain operational at all times and fully backed up with emergency protection.
