Dutra Construction is in the final months of completing the $22 million San Francisco West Harbor renovation project. The project broke ground back in April 2011 and will be complete by January 2013.

To date, over 70,000 cubic yards of material have been dredged, over 250 piles installed, and multiple concrete docks built that are home to over 210 new boat slips. Dutra also constructed a sheet pile breakwater at the entrance to the harbor for wave protection, renovated the historical harbormaster building and performed various other site improvements. The greatest challenges to date have been the removal of an old land mass known as the "West Mole" and dredging and backfilling in contaminated soil areas.

Currently, 14-inch concrete piles are being installed at F dock, which is adjacent to Marina Boulevard. At the same time, contaminated material is being dredged in the portion of the harbor adjacent to the Marina Green. This area will be capped with three feet of sand to bury the remaining contaminated material, leaving the final depth seven feet lower than before. November will be a busy month during which crews will install the remaining piles and docks and build a 225-feet floating wave attenuator that will be installed at the entrance of the harbor to reduce surface waves from entering the marina. The wave attenuator will be anchored by heavy duty chain connected to pipe piles driven into the bay floor. This activity will be the capstone to this historical marina renovation project.
