EEIS Consulting Engineers, Inc. (EEIS) was the prime consultant for the project, providing architectural/life safety design and civil, structural, mechanical HVAC, and electrical engineering. The hangar building contained 33,600 square feet for aircraft storage and light maintenance and two-story office areas of 4,848 square feet and 3,196 square feet; one area on each end of the building. Civil design services included water and sewer, a 590-foot apron, a fueling station, parking areas, and landscaping. EEIS was responsible for permitting the project with Ted Stevens Anchorage International Airport, Anchorage Water and Wastewater Utility, Alaska Communications, Chugach Electric, and the Municipality of Anchorage.
The project consisted of providing architectural/life safety design and civil, structural, mechanical HVAC, and electrical engineering for an 18,000-square-foot hangar with 11,000 square feet of office and support space. Civil design services included 580 feet of new access road, a 210-foot mainline sewer extension, a new section of aircraft apron and taxiway at the front of the hangar, a fueling station, parking, and landscaping. EEIS was responsible for the lease application for the project site from Ted Stevens Anchorage International Airport (TSAIA) and all permitting for the project. This included permits from the US Army Corps of Engineers, Anchorage Water and Wastewater Utility (AWWU), Alaska Department of Transportation and Public Facilities, Municipality of Anchorage, and TSAIA. EEIS also coordinated installation of utilities with AWWU, Alaska Communications, and Chugach Electric.
EEIS provided architectural/life safety design and civil, structural, mechanical HVAC, and electrical engineering, as well as design management, for the construction of a hangar. The hangar included an 18,000-square-foot aircraft storage area, a 4,500-square-foot fixed base operations center, and 15,500 square feet of Class A office space on two floors. Civil design services included vehicle parking and access roads, the apron between the hangar and the taxiway, an aircraft fueling area, water and sewer service lines, a sewage lift station, landscaping, and security fencing.
Structural engineering provided included procuring documents for the pre-engineered metal building and hangar doors, designing the office and operations mezzanines, and designing the foundation for the hangar building. The Fairbanks Air Hangar was a fast-track project, with construction beginning before the design was complete. EEIS supported permitting with the Fairbanks International Airport and the City of Fairbanks, and coordination with the local utilities. EEIS also provided construction support.
As a subconsultant to BDS Architects, Anchorage, EEIS provided structural design and served as the engineer of record for the 20,700-square-foot aircraft hangar with an additional 11,600 square feet of support and office space. One challenge for construction in Utqiaġvik is the availability of only one barge a year to bring in construction materials. Missing the barge can result in loss of a whole year from the construction schedule or incurring high costs of air freight. To avoid the risk of delay or increased cost, the project used early procurement of owner-furnished materials and awarded the contract for the sitework and pile installation before the building construction contract. The sitework and pile driving to took place in the fall, and the purchase of the pre-engineered metal building and award of the construction contract followed the next year.
To design the foundation before the building was purchased, EEIS provided calculations and designed a foundation for that building and then specified the building requirements. Project deliverables included drawing and specification packages for early procurement, sitework, and building construction. The EEIS structural engineering included the design of the foundations for the hangar building, aircraft doors, thermosyphon supports, and a 60-foot-tall communications tower. EEIS also provided design for the concrete floor slab and the second- and third-story mezzanine floors.
EEIS provided architectural/life safety design and civil, structural, mechanical HVAC, and electrical engineering for the 6,050-square-foot, two-bay hangar that included restroom facilities. The hangar site overlooked Lake Hood. The steel pre-engineered building had insulated metal roof and wall panels, a foundation and slab of reinforced concrete, and two 50-foot-wide sliding doors for aircraft entry.
EEIS was the prime consultant providing structural engineering to replace a 58-foot-tall hangar door on a Hovercraft Storage Building on the Oliktok Point Pad at the Nikaitchuq Development. The existing hangar was a fabric building with fabric doors that did not work well. The old door was replaced with a new roll-up door. The roll-up door required an enclosed structure to support and protect it. The new hangar door enclosure had a steel frame supported on steel pipe piles embedded 20 feet below grade. The walls of the enclosure were framed with metal studs that supported light-gauge metal panels. EEIS also provided shop drawings for the structural steel, metal studs, and flashings.
EEIS was prime consultant providing architectural/life safety design and civil, structural, mechanical HVAC, and electrical engineering. The project was two duplex hangars. One building had two 3,600-square-foot hangar bays, and the other had two 3,000-square-foot hangar bays. Civil engineering included an access road, taxiways, and water and sewer lines. EEIs coordinated permitting with the Municipality of Anchorage.
