Port San Luis Harford Pier Stabilization

Constructed in the late 19th Century, the Harford Pier comprises a core part of the Port of San Luis (Port) facilities and provides significant historic and economic value. The original buildings established on the pier were destroyed by fire in 1915 and rebuilt into the pier’s current structures in 1919. Since then, the structures have undergone numerous emergency repairs such as removing portions of the pier due to long-term wood decay and other wear and tear.

Cannon was selected to develop an action plan in response to the Port’s need for the Harford Pier’s preservation, repair, and maintenance. The action plan included a review of the existing studies, site visits to document current conditions, schematic repair scenarios, cost estimates for construction repairs, and prioritization of the recommended repairs.

For Phase One of the Harford Pier project, Cannon provided structural design for stabilizing the warehouse roof structure. This involved inspecting existing piles and pier caps to determine the expected scale of required work, new piles and pier caps, new treated columns, a new beam, stabilization of the west columns to roof truss connections, and a new shear wall.

In Phase Two, Cannon designed repairs to the pier south of the warehouse roof and in the southeast section. Numerous piles were installed and approximately 50% of the pier caps were replaced along with most of the joists and decking. Phase three involved repairs to the pier area in breezeway between the Harbor Patrol offices and seafood market. Cannon updated pier drawings, provided investigation within the vicinity of the breezeway, prepared design documents, and provided construction administration.
