Treasure Island Ferry Terminal, Treasure Island, San Francisco, California

Liftech provided the structural design of the steel float for a new ferry terminal located at Treasure Island. 

The design included the float structure, support and connection to the gangway ramp, guide pile collars to restrain the ramp laterally while permitting vertical motion, access for future battery systems, and berthing, mooring, and access systems compatible with WETA ferry vessels and operations.  The future battery systems would be installed inside the float through hatches in the float deck and would charge electric ferries that entities such as WETA are currently considering adding to their fleet.

In the image above, the float is at the end (pier and gangway designs provided by others).
