Moffett Field Hangar, Overall Project, Mountain View, California

At more than 1,000 feet long, 250 feet wide, and 170 feet tall each, two blimp hangars constructed in the 1940s at Moffett Field are among the world’s largest clear-span timber structures. One of these hangars had significant damage to many of its timber truss arches, and the damage was progressing along the length of the hangar to the extent that there was concern the hangar, or portions of it, could collapse. Power retained Liftech to design systems to stabilize and provide access so Power could safely perform repairs.

Moffett Field Hangar, Access Shoring Tower System, Mountain View, California

Liftech designed an access shoring tower system and strand jack assembling system. The access system is 80 feet x 80 feet x 130 feet tall. It is designed to shore and jack the hangar roof from its deck and facilitate access to the roof with an array of equipment on its deck including lifts and cranes. It is designed for asymmetric shoring, can resist large lateral loads, and can tip onto one side in an earthquake.
