Washington Engineering provided design and construction support for a 23,800 sf aviation maintenance hangar facility. The facility provides space for the Fixed Base Operator (FBO) and for relocation of Avian Aeronautics from an obsolete facility.
The structure is a metal building system with a height of 38-feet, a length of 160-feet and width of 125-feet. The controlling design feature is an 9,500 sf hangar bay with a vertical clear inside height of 26-feet. The hangar is accessed through an 84-foot clear opening, standard 4-panel aircraft rolling hangar door. The building is supported on a reinforced concrete foundation with a concrete slab-on-grade floor designed to support corporate jet aircraft. The interior of the hangar bay, including the concrete slab, is painted white for light reflectivity.
Adjacent to the hangar bay, is a 31-foot wide by 125-foot long, two-story bay that provides space for Fixed Base Operations (FBO) and administrative functions. Within this area are reception areas, offices, a small conference room, pilot ready rooms, pilot break rooms, a galley and restrooms. This facility is the centerpiece of aviation related activities at Bremerton National Airport and has been designed with a prominent and aesthetically pleasing entry into the reception area from both the flightline and vehicle parking areas, and with durable, upscale exterior finishes.
A series of aircraft part maintenance shops are located on the rear side of the hangar to support relocation of Avian Aeronautics to the new facility. These shops include engine disassembly, parts cleaning, non-destructive testing (NDT), engine assembly and test areas. Also supporting the Avian work areas there are administrative support offices, a technical library, and shipping and receiving areas. Shop, restroom and breakroom facilities were provided to support personnel working in the hangar and shop areas.
The hangar bay includes an in-slab hydronic radiant heating system. The building was designed to meet the fire protection requirements of NFPA-409. The hangar bay is separated from other areas of the building by one-hour rated walls and the entire facility is sprinkled for fire protection.
The site for the facility, between the existing Terminal Building and the Fueling Facility, was adjacent to most utilities. The existing access road was relocated and new parking and storm drainage constructed. A roof drain infiltration system was designed and stormwater runoff from 11/5/2020 Washington Engineering wa-eng.net/projects/ptbremavian.html 2/2 the site was treated to remove sediments and oils. Electrical power, communications and natural gas utilities were extended to the project site.
Major features of the building include:
- Prepared site and building permitting data
- Metal Building System on Concrete Foundation with hydronically heated Slab-on-Grade
- High quality insulated standing seam metal roof
- Mechanical, Electrical and Fire Protection Systems
- Site Utilities, Access Road, Parking and Landscaping
- Provided construction support services
