Scope of Work:
Interior Demolition, Selective Demolition, Dismantlement
Hangar 7A and 7B were originally designed and custom-built to accommodate Boeing 757 aircraft. Work included modifications to Hangar 7A and 7B to enable simultaneous maintenance of multiple smaller regional jets. Work was completed in two distinct phases as to allow normal operations of the adjacent Hangar to continue during demolition and renovation activities. The first phase of demolition involved interior modifications to Hangar 7A. During this phase, a specialty aircraft maintenance mezzanine was completely dismantled and removed. In addition, many of the existing ventilation, electrical and fire suppression systems servicing overall Hangar were modified. The second phase involved similar work in adjacent Hangar 7B. These modifications included the removal of the specialty maintenance mezzanine along with removal of an adjustable three to five level suspended work dock. The hangar floors had to be protected during both phases of work as not to damage the intricate and delicate radiant heat system located two inches beneath the floor surface.
This project was unique because the hangars were active and occupied with mechanics and tenants that could not be disturbed during the renovation. With mechanics working on jet engines in close proximity all noise, vibrations and dust had to be properly controlled. Upon completion of work, O’Rourke Wrecking Company completely hand vacuumed and wiped the hangar from ceiling to floor to mitigate the potential for concrete dust negatively impacting a jet engine or airplane.
