Northwest Demolition’s experience and specialized equipment has made it a leader in the removal of docks, bridges and other improvements adjacent to or over water. This experience has included remote location projects accessible only by water.

One example was a contaminated soil removal project on a remote Pacific Island, where Northwest Demolition provided transportation (by ship), housing, medical support, and communications in addition to performing the project work.

Example Marine Demolition Projects

Dock Demolition

Northwest Demolition was contracted to demolish two massive, badly deteriorated docks measuring a combined 2,600 feet long (250,000 square feet). These large, creosoted wood structures were demolished to enable the construction of a burial zone for contaminated sediments dredged from the surrounding waterways.

Dam Demolition

This project required specialized excavators outfitted with hydraulic impact hammers and concrete pulverizers. Working under a tight schedule, the large equipment allowed the rapid and timely removal of the structure. This was of particular importance due to the environmental and political sensitivity of this project.

Marine Terminal Demolition

This project involved the removal of approximately 250,000 square feet of warehouse built upon a debilitated dock structure. The dock structure was in varying condition. Risk of structural collapse was a constant concern. Following extensive asbestos abatement, over two million board feet of structural timbers were salvaged from the project.

Slips, Wharfs, Dolphins & Pilings Demolition

Removal of four shipways, two concrete piers, two wooden piers, and fourteen concrete capped moorings. Two piers were demolished from atop the structures and two required the use of barges. It was necessary to coordinate tides, multiple subcontractors, the busy ship passage while working within the scheduled fish window restrictions.
