San Francisco Marina West Harbor Renovation

Project Description

This design-build project consisted of designing the new marina, demolishing the existing wood docks, piles and gangways, and dredging to a depth of -12 feet. Over 100,000 cubic yards of sediment were removed, with disposal of 15,000 cubic yards of contaminated material at an upland site.

The project consisted of furnishing and installing new concrete docks to create 385 slips of various lengths and widths, driving over 400 piles, upgrading utilities services, and building a fixed sheet pile wall breakwater. The capstone of the project involved design, fabrication and installation of a 225 foot floating wave attenuator to protect the marina entrance.

Major Challenges

Keeping the marina operational and existing facilities intact during construction was a major challenge. Dutra implemented a strategic project phasing plan that allowed for up to two hundred boats of varying lengths to remain inside the marina throughout construction.
