Washington Hospital serves the Silicon Valley suburb of Fremont, California. Bigge was hired to perform the lift and set of structural steel used to construct a pedestrian bridge. Our work took place over the course of two weeks. We dispatched a Liebherr LTM 1400 7.1 All Terrain Crane and a Link-Belt HTC86100 Hydraulic Truck Crane to perform the first phase. Weighing 85,000 pounds, a 56-foot section, roughly one-third of the overall structure, was delivered to the job site. The cranes and crews worked in tandem to trip the steel to the correct orientation. The load was then re-rigged, and the All Terrain hoisted the piece, setting it onto concrete abutments.
With the support of other mobile cranes from our fleet, our customer completed the fabrication of the remaining bridge sections on-site by splicing together two additional units. With an overall length of 112 feet, the structure was loaded onto our 9-axle trailer by the LTM 1400 and then rolled down the driveway to the location of the second crane setup. The 150,000-pound load was rigged and hoisted into place on corresponding abutments to complete the procedure.
This pedestrian bridge will join a new seismically compliant facility to the original hospital building as part of the hospital district's overall modernization plan. Our cranes and crews participate in similar projects in the Bay Area and across Northern California.
