San Francisco’s Fort Mason Pier Undergoes Large Underwater Strengthening For Seismic Performance

Share Article

Fibrwrap® Construction Inc. has announced the successful completion of a large scale underwater FRP strengthening project on the Fort Mason Pier in San Francisco. The Tyfo® PR Fibrwrap® System was used to provide additional strength to 300 piles that support the pier. In total, approximately 700,000 square feet of Fibrwrap® was installed beneath the pier.

“The initial design for the Fort Mason Project used traditional methods. This pushed the estimated cost of the project up to $40 million dollars,” Said Ed Fyfe, President of Fyfe Company LLC (http://www.fyfeco.com), manufacturer’s of the Tyfo® FRP Systems “By conducting the retrofit with our Tyfo® PR System, the contracting team including Fibrwrap Construction Inc. was able to complete the project for half of the original estimate.” http://www.fibrwrapconstruction.com

This project was designed to address deficiencies in the concrete piles supporting the Fort Mason pier. It was determined that the pier structure did not meet the necessary requirements for seismic performance. Because the piles descend to an average depth of 30 feet below the water line, specially formulated resins were used to ensure full cure underwater. To ensure the correct placement of the Tyfo® PR jackets, they were lowered from floating platforms with skilled divers.

Work was completed over the course of twelve months by Fibrwrap® Construction Inc.’s technicians. The Tyfo® PR jackets include the innovative use of an FRP spring damper to ensure they maintain their position around the existing concrete piles during installation. Following the successful completion of the Fort Mason project the Tyfo® PR System was also used to reinforce piles on San Francisco’s landmark Fisherman’s Wharf.

Fyfe Company’s (http://www.fyfeco.com) Tyfo® PR jackets are advanced composites, or FRPs (Fiber Reinforced Polymers) that Fibrwrap® Construction Inc. uses to add strength and ductility to structures that are in need of upgrade, repair, seismic retrofitting or rehabilitation. This includes not only concrete and wood piers, but also bridges, buildings, pipes and other structures.
