PDCA PROJECT OF THE YEAR AWARD – 2017
This work represented the first phase of a multimodal project to relocate the existing Mukilteo Ferry Terminal to a former U.S. Department of Defense fuel storage facility known as the tank farm. The property includes a large pier extending into Possession Sound.
The project was accomplished while complying with environmental constraints from over 12 different federal and state agencies.
Deconstruction of the tank farm began in 2015 with a planned construction schedule of two years. In-water work was restricted to between July 15 and Feb. 15 each season, with some elements, such as dredging and pile extraction, further constrained by the National Marine Fisheries Service.
Pacific Pile & Marine utilized a shearing method to remove the pile, significantly reducing the duration required for demolition, condensing the in-water work window to a single season. Twenty-one thousand cubic yards of material were dredged in the navigation channel for open-water disposal.
