• Furnished, assembled, and operated the self propelled Scheuerle hydraulic platform trailers
• Lifted and weighed the 1,800 ton bridge section, and loaded it on a barge in Oregon
• After the barge was positioned under the Bay Bridge, rotating the bridge section 90 degrees on the barge for the lifting operation
• Bigge also furnished and operated the strand jacking lift system, including a pair of 1,000 ton capacity girders on a 125 foot span on the east, a pair of 60 foot long 1, 000 ton capacity girders on the east, and Hydrospex strand jacks which accomplished a 200 foot vertical lift in approximately 8 hours and side-shifted the section precisely into position
