Project: Aircraft hangar, part of a larger industrial building, completed for Ola Tronrud
Location: Eggemoen, Hønefoss
Client: Ola Tronrud AS
Contract: Aircraft hangar
Building Specifications: 30m x 30m
Purpose of building: The facility is used for the storage and maintenance of aircraft.


This aircraft hangar is a part of a bigger industry building complex that Hallmaker completed for our client Ola Tronrud. Hallmaker used the same suppliers and materials that were used for the entire building project, to retain the overall look and aesthetic appeal.


During the process Ola Tronrud designed, produced and mounted the two doors onto the hangar.


The large door measures 22m x 6.4m and features a sandwich panel (adjusted for size requirements) and the same mounted glass that has been used throughout the building. The door weighs 2500kg.


The smaller door measures 11.8m x 5m and weighs 1000-1200kg. Both of these doors were
constructed with hydraulic lifting cylinders, giving them the abilty to open to almost 90 degrees.
