Y--SPECIAL NOTICE - INDUSTRY DAY/PROJECT PRESENTATION - National Mall and Memorial

The Department of the Interior, through the National Park Service Denver Service Center, is conducting market research via a Sources Sought Notice for solicitation 140P2026R0104. The project, titled Rehabilitate Seawalls and Shoreline (Phase III), focuses on the removal and reconstruction of historic stone masonry seawalls and shoreline stabilization at East Potomac Park in Washington, D.C. The scope is divided into two primary sections: one extending from the Inlet Bridge south to Hains Point along the Potomac River, and another from the Outlet Bridge south to the I-395 bridge along the Washington Channel. Key deliverables include the reconstruction of sidewalks and railings to create an accessible continuous pathway and the replacement of adjacent landscaping. The project will require compliance with Washington D.C. building permits and USACE Section 404/408 environmental coordination for in-water marine construction. The government anticipates awarding a single firm-fixed-price contract using a best-value Design-Bid-Build approach, with an expected period of performance of 1825 calendar days. The project falls under NAICS code 237990 and will require bid, performance, and payment bonds, as well as insurance. While the current phase is for market research to determine potential small business or socio-economic set-asides, a formal competitive RFP is expected in fall 2026. Amendment 01 has extended the response deadline for the sources sought notice to September 16, 2026, and has added industry day materials, including a sign-in sheet, presentation slides, and a contractor question document addressing logistics such as dewatering, staging, and public access impacts.
