Fix for corrosion problem on new Colman Dock piles could cost as much as $10 million
SEATTLE – Consultants charged with studying an accelerated corrosion problem on steel piles for the new Washington State Ferries terminal at Colman Dock have recommended a fix estimated to cost as much as $10 million.
That solution would be designed to protect 173 piles that were driven into Elliott Bay for the project in the fall of 2017. About 500 total piles have been installed as part of the massive reconstruction effort on the Seattle waterfront.
In 2016 and 2017 value engineering efforts aimed at saving on costs at Colman Dock, project officials decided to add additional thickness to the dock’s steel piles to achieve a targeted 75-year lifespan and not use a marine coating system, which must be maintained, Ferries Director of Terminal Engineering David Sowers said in an interview with the Kitsap Sun. The coating system is used on piles at the agency’s other locations throughout Puget Sound, he noted.
“We thought this value engineering approach would be successful and would also eliminate us from having to do that maintenance step in 30 years,” he said.
