C5 Maintenance Hangar
Organization: West Virginia National Guard 167th Airlift Wing
Project: Construction of an 80,000 square-foot maintenance hangar
Location: Martinsburg, WV
Carney Engineering Group (CEG) managed the new construction of an 80,600 square-foot maintenance hangar with offices, a conference room, locker rooms and large service areas. CEG was also retained by the general contractor to provide general consulting and field engineering services during construction.
The hangar required clearspans of 254’ at the front of the building, and approximately 220’ from front to back to accommodate the clearances for the C-5 wingspans. The main trusses were over 400,000 pounds each and required six shoring towers up to 50’ high to construct. CEG was retained by the fabricator to provide connection redesign for the trusses to reduce fabrication cost, to provide erection sequence consulting, and to design and detail the shoring towers. The shoring towers were designed to carry loads up to 800,000 pounds of steel dead load during construction and had an innovative jacking system incorporated into the seat to allow for adjustments to the structure as well as removal after the complete structure was in place.
