Port of Longview – Berth 4 Layberth

Project Details

Prime Contractor: Advanced American Construction
Owner: Port of Longview
Location: Longview, WA | October 2015 – March 2016

The Berth 4 Layberth was constructed by AAC to provide additional berthing for ships waiting to load and offload at the Port of Longview, with the new layberth being constructed in a location where a previous timber dock had existed. These obstructions, along with tight tolerances for pile placement, created a challenge, but AAC still completed the project three weeks ahead of schedule.

AAC worked with National Pipe and Pile to provide the spin fin pile, while Staton Companies provided demolition and disposal assistance with the existing structure that needed to be removed, and the 8 aluminum walkways were provided by Mantle Industries.
