NAMA 320066 Rehabilitate WWII Memorial Infrastruct

This government document outlines the construction plans and technical drawings for project PMIS/PKG No. NAMA-151062 (Contract No. P12PC20333) to repair the failed slurry wall, pool membrane, associated electrical systems, and foundation drainage system at the World War II Memorial, located within the National Mall and Memorial Parks in Washington, D.C. Prepared for the National Park Service (NPS) Denver Service Center, the plans detail repairs executed by contractor Clark Construction Group and designed by A/E firm The Louis Berger Group. The document contains comprehensive civil, structural, geotechnical, and electrical engineering sheets. Key technical components include: - A detailed index of drawings, legends, abbreviations, and general construction notes. - Geotechnical boring logs and dilatometer test results used to establish soil conditions and depth to bedrock. - Mapped locations of known leaking panels, cut-outs, and test pits to expose and inspect the exterior face of the slurry wall. - A systematic triple-row jet grouting plan (Rows A, B, and C) detailing column installations socketed into bedrock (varying between 35 to 50 feet deep) to form a watertight barrier. - Detailed cross-sections outlining the spatial relationships between the Lincoln Memorial Reflecting Pool drainage pipes, storm sewer system repairs, and the main vault of the World War II Memorial. Additionally, the notes specify strict guidelines for the contractor regarding site maintenance, temporary staging plans, utility coordination, safety protocols, and the requirement to submit daily updated as-built records in AutoCAD format.

This Sources Sought Notice (SSN), issued by the National Park Service (NPS) Denver Service Center, seeks market research information to determine the acquisition strategy and potential small business set-asides for a design-build project to rehabilitate the World War II Memorial in Washington, D.C. The project addresses deferred maintenance, weathering, and aging systems. Key scope items include repairing granite elements, restoring walkways, improving storm drainage, waterproofing fountains, upgrading mechanical, electrical, and plumbing systems in the subterranean vault, and modifying approaches to comply with accessibility codes. Because the memorial will remain open to the public, construction must minimize visitor impact and protect the historic site. The anticipated period of performance is 365 calendar days, and winter construction may be required. The NPS anticipates issuing a competitive Request for Proposals (RFP) for a single Firm-Fixed-Price contract around November 2026. The applicable NAICS code is 238990 (All Other Specialty Trade Contractors) with a $19 million size standard. Interested large and small businesses must submit their qualification details, including bonding capacity, licensing plans, self-performance percentages, and past design-build experience, to Contracting Officer Marc Nguyen (marc_nguyen@ios.doi.gov) by 12:00 PM Eastern Time on October 15, 2026.
