Port engineering orders load limits on Pier 3032 after deck failure; events and bus parking affected

Summary
Port engineers told commissioners a punching-shear failure in Pier 3032’s deck led staff to restrict heavy vehicles and buses, propose signage and a height-restriction portal, and seek funding and design options to restore access; two special events were canceled and short-term parking moved to Seawall Lot 337.
Port of San Francisco engineering staff told the Port Commission that a recent deck failure at Pier 3032 has forced an immediate restriction on heavy vehicles and buses and will affect special events and tour-bus parking.
"The deck failure is classified as a punching shear failure," said Ed Byrne, the port’s Chief Harbor Engineer. Byrne described a large hole caused when a heavily loaded truck punctured the century-old pier slab and said the structure lacks top reinforcing steel in the affected slab areas.
Structural engineer Joe Rogier showed slides of the damage and a load-capacity analysis, saying, "Piers 30 and 32 are limited to a 2,000-pound wheel load." Rogier said the connecting pier built in 1950 is stronger, but the approach from the Embarcadero to the connecting pier is the weak link. To reduce risk, he proposed electronic signage, additional static signs, and a front-entry portal height restriction to keep oversized trucks off Pier 3032.
Joyce Chan, property manager in the port’s real estate department, told the commission the limits already forced event cancellations. "Today, we received two special events cancellations, Ben's Warp Tour and AVP Beach Volleyball," Chan said, and said Imperial Parking has relocated tour-bus and truck parking to Seawall Lot 337 as a short-term measure. Chan estimated the annual potential loss of revenue from special events and tour-bus and truck parking at $124,000.
Commissioners asked staff about rebooking events and alternatives; staff said some events, such as those wanting waterfront views, may not be movable to other lots but that cross-department work is underway. Port staff said engineering, real estate, maritime, planning and finance are developing options and potential funding sources to restore operations while keeping the pier open for lighter public assembly and parking of light vehicles.
Because the failure resulted from a concentrated heavy wheel load on a thin slab without top rebar, staff stressed the measure is precautionary but necessary until structural repairs or longer-term rehabilitation can be funded and delivered. The commission did not adopt a specific repair plan at the meeting; staff said it will return with options and cost estimates.
