Narrative:

Taxiing from the FBO ramp and with 2 other aircraft very close (in front and to the right) and with 40000 pounds of weight (tow); we were not signaled out of the ramp by the ramp guys (they were watching the other 2 aircraft close by). We had to make a hard right turn to avoid the aircraft parked in front. The right landing gear ended up in the grass area to the right of the ramp. Upon inspecting it; the tire was only about an inch deep. So I decided to take it out of there with power (only 2 engines running). We requested the ramp guys to open the hangar doors behind us; so we wouldn't damage it. The sic helped them open it and came back to the airplane. We waited 2 mins for them to finish. When powering out of the grass; the engine thrust damaged the doors and made them loose. The door frames went into the hangar and damaged 5 airplanes.
