Shelby Airport Hangar

Project Description

The Shelby Airport Hangar is a 100’ x 80’ clear-span, insulated pre-engineered metal building constructed with tapered built-up steel frames, and clad in metal roof and wall panels. Aircraft access is provided through a large electric bi-fold door. This revenue-generating hangar is sited on prime apron frontage, and provides storage and shelter from the elements for either a single large “premium” aircraft, or multiple smaller aircraft.

The building has a concrete foundation and footings engineered to resist the code-prescribed gravity and lateral loads imparted by the pre-engineered metal building, with a concrete floor and exterior concrete slab connecting to the apron. The building is fully insulated and heated with overhead radiant heating. Design of the hangar included building appropriate localized drainage slopes and ditch lines to direct surface water around and away from the hangar. Due to the total fuel capacity of all stored aircraft exceeding 1600 gallons, the Current Fire Code required installation of a fire suppression system (FSS).

Ennis Big Sky Airport

Project Description

Ennis Big Sky Airport is open and fully operational following completion of their $15.3M major airport improvement project(s) to expand their runway to meet FAA required safety upgrades for their substantial use aircraft grouping.  Improvements included land acquisition, full reconstruction of their existing runway, widening the runway to 100’ width, lengthening their runway to 7,600’ total length, constructing a 50’ wide full length parallel taxiway (shifted away from the runway), reconstruction of their south apron, construction of hangar access taxilanes, major electrical and navigational aid improvements, major drainage improvements, and wildlife fencing.  

Robert Peccia and Associates was the engineer for all improvements, and SK Construction was the prime contractor for the construction project. 

Key Information:

  • Land acquisition – 11 different parcels were acquired from 11 different landowners.  In addition 4 construction easements / permits were attained
  • Earthwork – Nearly 1.2M cubic yards – enough to bury a football field 675’ deep
  • Drainage / Culverts – over one mile of storm drainage culverts (5,528’) – largest culvert was 60” diameter so you could walk through it hunched over
  • Gravel – Nearly 60,000 CY of subbase and base course gravels
  • Asphalt – Over 38,000 tons of asphalt (1,300 truckloads)
  • Paint – over 43,600 square feet of paint
  • Lights – 284 runway and taxiway lights and an additional 22 lighted guidance signs
  • Cable – over 61,000’ of electrical cable (11.6 miles)
  • Fence – over 26,400’ of fencing (5 miles) and 29 gates
