17th Street Dock Reconstruction

Location: Astoria, OR
Owner: City of Astoria
Contract Value: $4,500,000
Completion Date: September 2013

Bergerson Construction was awarded the contract to remove and replace this pier in June 2012. After award, Bergerson’s team worked with the City to save over $100k through value engineering changes, which allowed the City to implement additional upgrades to the facility.

The 109 steel pipe piles were installed through a silty riverbed into the dense siltstone. Given restrictive in-water work requirements, Bergerson worked closely with the City to install all piles during a one month period, thus avoiding costly marine mammal monitoring. The entire pier was removed (including extraction of over 200 piles) over the next month to meet a very limited in-water work window.


The cast-in-place concrete pilecaps and pre-stressed deck slabs were installed over the next few months. Close coordination was necessary throughout the project to allow for installation of water, sewer, communications and electrical in a utility trench that was constructed in the concrete pier. This award-winning project was completed ahead of schedule and under budget.
