Engineers tell Portland Fish Pier Authority Service Piers need near-term repairs; service pier 1 highest priority

Tech Associates engineers told the Portland Fish Pier Authority on a Zoom meeting that parts of the fish pier complex show significant corrosion and that Service Pier 1 is the highest priority for repair.

The consulting team’s survey of sorting piers and service piers found that most of the sorting piers are in relatively good condition, but Service Pier 1 and parts of Service Pier 3 show enough section loss and damage in the splash/high‑tide zone that “something needs to be done in the near future,” Gordon Armstrong of Tech Associates said. Gabriel (Gabe) (Tech Associates) said several piles and braces measured “to zero” at specific locations during field testing, and that the worst damage is concentrated at the high‑tide splash zone.

Tech Associates said it modeled existing geometry, measured corrosion and compared the remaining capacity to applicable design loads. The engineers described their percent metric as “percent of allowable load in use,” where lower numbers are better and values above 100 percent…
