The National Park Service is seeking construction services for two critical stabilization projects at Vicksburg National Military Park in Mississippi through solicitation 140P2025R0092. The procurement covers stabilizing Mint Spring Bayou through slope stabilization using high-capacity strand anchors and reinforced granular fill, and stabilizing terraces and graves at the National Cemetery by constructing approximately 272 linear feet of soldier pile and lagging retaining wall to repair landslide damage and restore Given Hill Road. Key contract requirements include mobilization, archaeological monitoring, soil anchors and drainage systems, soldier pile wall construction, excavation, grading, and comprehensive site restoration with environmental protection measures. The contract will be awarded as a firm-fixed-price construction contract evaluated on technical capability, past performance, and price factors. Important dates include a pre-proposal site visit held on September 9, 2025, a deadline for requests for information on September 16, 2025, and proposal submissions due by October 3, 2025.

This opportunity is designated as a total small business set-aside under NAICS code 237990 for Other Heavy and Civil Engineering Construction, with an estimated contract value exceeding $10 million. No current incumbent contractors are identified in the solicitation materials. The project involves a 548-calendar day performance period for completion of the complex geotechnical work, which includes installing multiple rows of ground anchors, constructing soldier pile walls with HP 14x102 and HP 18x135 piles at 8.5-foot spacing, and restoring approximately 1,751 square feet of wetland and 6,774 square feet of upland areas. Construction will be performed at Vicksburg National Military Park in Warren County, Mississippi, with primary access through North Washington Street. The contractor will be required to obtain multiple permits including street closure, heavy load road, stormwater pollution prevention, land disturbance, and Archaeological Resources Protection Act permits due to the historically sensitive nature of the cemetery environment.
