Expression of Interest - Fabrication of a Pretreated Waste Storage Tank (PWST)

Hanford Tank Waste Operations & Closure LLC (H2C), acting as prime contractor to the U.S. Department of Energy's Hanford Field Office, is conducting market research through this Expression of Interest (EOI) to identify qualified fabricators for a pretreated waste storage tank (PWST) in support of the 200 West Area Tank Farms Risk Management (WARM) project. The procured services will involve the fabrication of a hazardous/dangerous waste storage tank designed to support long-term cesium removal operations and facilitate tank waste supernate removal from the Double-Shell Tank system. This WARM project serves the Integrated Tank Disposition Contractor's (ITDC) mission to provide space for Single-Shell Tank waste retrievals. The EOI is part of the final design phase and represents market research rather than a formal solicitation; responses will inform the development of subsequent solicitations. The deadline for submitting expressions of interest is March 9, 2026, providing interested parties approximately six weeks to respond to this initial inquiry.

No set-aside designations have been applied to this procurement opportunity, making it open to all eligible contractors. While the pre-solicitation notice does not identify specific incumbent contractors or current vendors, H2C is identified as the prime contractor managing the project for DOE. The notice does not disclose specific award values, budget ranges, or detailed technical specifications at this stage, as this EOI is intended primarily for market research and capability assessment rather than formal proposal solicitation. The WARM project is classified as a capital asset project subject to DOE O 413.3B's Critical Decision process, suggesting substantial scope and potential contract value. The procurement falls under NAICS code 332999 (All Other Miscellaneous Fabricated Metal Product Manufacturing), indicating the specialized nature of the metal fabrication services required.
