W. T. Rich Company was engaged by Rubb Building Systems to construct a new United Airlines hangar at Logan Airport. The size of this new hangar is 270 feet long with a clear span of 240 feet and a height of 80 feet. This immense structure is supported by woodpiles on concrete spread footings with concrete grade beams supporting a perimeter foundation wall. The superstructure is a curved truss system covered with a special canvas material that is both weather tight and translucent. The doors to the hangar are approximately 55 feet high and are installed on railroad track rails. The hangar is furnished with an infrared radiant heating system; the heat occupies the vast space along with a very special, state-of-the-art fire protection system. The fire system is so sensitive that a cigarette lighter could activate it and upon call, the entire hangar is immediately flooded with five feet of foam from the nozzles above. W.T. Rich completed this complex in seven months – one full month ahead of schedule.
