How to bid on Maintenance Dredging at Yokohama North Dock for the US Army Corps of Engineers
What the agency is buying and why it matters
The US Army Corps of Engineers, Japan Engineer District, needs maintenance dredging services at Yokohama North Dock in Kanagawa, Japan. This project involves removing naturally occurring bottom sediments like sand, silt, and clays from Berths 1-7 and A-L within the United States Exclusive Use Area. The goal is to ensure safe passage for watercraft and support mission requirements. The work includes conventional hydraulic or mechanical dredging methods, as well as the transportation and disposal of dredged material.
This is a significant opportunity for local Japanese construction firms, with an estimated value between 1 billion and 2.5 billion Japanese Yen. It is a pre-solicitation notice, meaning the agency is preparing for an upcoming acquisition.
