3389 LCHD-ESS Section B - OCT2025.docx

This document is a contract specification for the design, construction, testing, and delivery of one Large Class Hopper Dredge (LCHD-ESS) for the U.S. Army Corps of Engineers' Portland District. The contract involves a single line item (CLIN 0001) for a complete hopper dredge project, with the work to be initiated only upon a formal Notice to Proceed from the Contracting Officer.

The accompanying special notice indicates that the USACE is seeking contractor feedback on complex technical specifications, including vessel notation requirements (ABS HAB(WB)), operational performance parameters such as current navigation capabilities (7 knot current with 2 knot speed over ground), transit speed (14 knots with empty hopper), and ship motion acceleration challenges. The draft specification invites potential contractors to provide insights on design and construction considerations, berthing requirements, and potential business-related concerns that might impact competition or traditional hopper dredge design approaches.
