Andersen Air Force Base, Yigo, Guam
The Department of Defense wanted to increase their capability in the Marianas by developing a maintenance hangar for the MQ-4C Triton Broad Area Maritime Surveillance (BAMS) Unmanned Aircraft System, a long-endurance, high-altitude drone with a wingspan of over 130 feet. The hangar needed to be constructed, commissioned, and operational before the newly purchased aircraft arrived on site. As the design arm of the Guam MACC Builders joint venture design-build team, we worked closely with the client and contractor to understand the functional, security, and sustainability requirements of an advanced military facility located in a volatile tropical environment.
The hangar provides interior enclosed maintenance space to perform scheduled inspections, airframe repairs, pre-and post-flight operations, as well as technical order compliance and aircraft modifications. The facility also includes a 1,500-square-foot Sensitive Compartmented Information Facility.
Given the facility’s strict security requirements, our team designed horizontal and backbone distribution systems, equipment and room layouts, and performed a stringent security / threat analysis. Specific features include 187 data / telecom ports, 29 closed-circuit TV cameras, 45 access controlled doors, wireless LAN networks, IP TV, building management system, fire alarms, PA and acoustic systems, as well as satellite communication and microwave intrusion detection systems.
Since the new aircraft was still in development, the project requirements continued to evolve to accommodate the drone’s operational and maintenance needs. We followed our client’s protocols throughout the design phase, strictly adhering to the dictates of the NavFac design and construction processes and standards. By conducting multiple design workshops, formal reviews, and sign-off procedures, we involved all vested stakeholders in the decision-making process.
We designed the hangar to withstand the extreme geotechnical and metrological conditions characteristic of Guam and to achieve LEED Silver certification.
