About this file

This amendment modifies a federal solicitation and associated contract drawings and specifications for a saltwater system project at a naval shipyard. The project involves upgrades and repairs to Dry Dock 8, including replacement of engine generator sets, addition of day tanks to the fuel system, use of corrosion-resistant enclosures and coatings, changes to concrete structures and piping, and revisions to site plans, schedules and notes on electrical and mechanical drawings. The Navy seeks offers by a specified due date for the products and services required to complete upgrades to the saltwater system that supports Dry Dock 8 operations at the shipyard in Virginia. Revisions to drawings and specifications are included with the amendment to guide offerors.
