Y--Pre-Proposal Site Visit

A pre-proposal site visit is being conducted for the Elbee Bend Bank Stabilization project under solicitation number 140P2026R0084, managed by the Department of the Interior’s Dsc Contracting Services Division. The project, classified under NAICS code 237990, aims to stabilize approximately 1,200 linear feet of riverbank along the Knife River at Knife River Indian Villages in Mercer County, North Dakota, to protect the Elbee Village Archeological Site and surrounding infrastructure including County Road 37, electric utility poles, parking areas, and park boundary fencing. Key deliverables include installing self-healing riverbank protection, placing riprap at the base of the eroding bank for toe protection, forming keys with buried material to prevent behind-bank scouring, compacted filling to eliminate voids, and applying vegetation or bioengineering solutions. The stabilization work will also create a visitor trail connecting Elbee Bend to the fishing hole and Sakakawea stabilization/trail. The anticipated period of performance is 356 calendar days, inclusive of seasonal and weather-related shutdowns, with winter construction possibly required. The site is remote, located 25 to 50 miles from the nearest suppliers and lodging, and all work must be carefully scheduled to minimize impact on park visitors since the site remains open during construction. No formal solicitation or proposal package is currently available; the full and open request for proposals is expected to be issued on or around July 1, 2026. This pre-proposal site visit is intended to allow potential offerors to assess the project location and conditions firsthand. The National Park Service anticipates requiring bid, performance, and payment bonds for the eventual contract, and special attention will be needed to ensure the surrounding natural and cultural resources remain undisturbed during all phases of work. The contracting office is located in Denver, Colorado, with Stormy Gallagher as the primary point of contact. The place of performance is in North Dakota, and while no pricing, evaluation factors, or delivery terms are available at this stage, the detailed scope and environmental constraints are outlined to help prepare qualified bidders for the upcoming solicitation.
