DD Construction came up with a clever way to efficiently erect aviation hangar for NetJets Inc., the tenant, while complying with the airport’s FAA requirements and permitting process. Instead of a crane, the company used shoring towers.
Justin Beall, owner at DD Construction, says, “We built the clear span system with shoring towers to support the carried load instead of a crane. Because the building was 45 feet tall at the high eave and the weight of the 190-foot rafter, we would’ve had to erect it with a crane. Crane requirements for the airport included having 5 miles of visibility, permitting and inspections, and daily communications with air traffic control. So, we decided to take a different approach that would not impede the airport operations and, in the end, save us some money. We built shoring towers to transfer the load and erect the rafters without the use of a crane and eliminate production loss due to something as minimal as overcast weather.”
To construct the 35,000-square-foot, 190-foot clear span hangar, DD Construction erected Butler Manufacturing’s metal building system and installed 24-gauge Galvalume MR-24 standing seam roof system with Azl-Plain coating and Butler’s 26-gauge Galvalume Butlerrib II metal wall panels in Cool Shell Gray.
Beall says, “After erecting the lower half of the roof due to the support of the shoring towers, we squared the lower half of the roof structure, installed our purlins and moved to the upper half of the roof. This was the process the entire time: shoring towers and telehandler forklift erection.”
