Reference: VICK 209252 Stabilize Mint Spring Bayou & VICK 310725/324137 Stabilize Terraces & Graves

This pre-solicitation announcement is to advise the Industry that NPS DSC intends on issuing an RFP Solicitation for the Construction Services described below, in support of the above referenced project requirement at Vicksburg National Military Park in Vicksburg, Mississippi.

This PSN is not a formal Solicitation in itself, but rather a Synopsis of forthcoming RFP 140P2025R0092.

Specific instructions on submitting your proposal will be contained in the solicitation documents to be issued on or after August/September of 2025.

General Project Description and Scope:

This project is located at Vicksburg National Military Park in Vicksburg, Mississippi. Work to be performed under this Construction Services project requirement includes:

Stabilize Terraces and Graves (VICK 310725/324137):

This project will provide for stabilization of terraces to protect the resource and mitigate the potential for injuries with the construction of approximately 272 linear feet of soldier pile and lagging retaining wall with an earthen buttress for slope stabilization to repair landslide at the National Cemetery and restore a section of Given Hill Road. Principal features of the work include mobilization and demobilization, clearing and grubbing, demolition of existing drainage features, fencing and existing pavement, site grading, excavation, select fills, asphalt paving, concrete paved ditches, retrofit of an existing drain inlet installing drainage structures and HDPE storm drain piping, soldier pile and lagging retaining wall including the setting of H-Piles, installation of permanent ground anchors and wood lagging, two-stage french drain and underdrain construction, new turf establishment, stormwater pollution prevention, temporary erosion control items, and environmental protection. Archaeological and cultural investigations will be conducted to monitor any ground disturbance and construction activities deemed necessary to protect archaeological resources.

Efforts between the National Park Service, US Geological Survey, Southeast Archaeology Center and the US Army Corp of Engineers’ Eastern Research and Development Center have determined that immediate short term stabilization efforts are needed to protect not only the cultural resources, which include remains of Civil War soldiers, but also protect anyone who may attempt to enter the site as it now is in an unsafe condition and susceptible to further deterioration.

Stabilize Mint Spring Bayou (VICK 209252):

The current stabilization scope for the Mint Spring Bayou project includes construction of a slope stabilization system consisting of high-capacity strand anchors with reinforced concrete anchor plates and placing reinforced granular fill in front of the anchor benches to stabilize the slope adjacent to the Mint Spring Bayou. In addition to the stabilization work proposed at the Mint Spring Bayou and due to continuous deterioration of the soils including the landslides at the National Cemetery, the project also considers the stabilization of the area (gap)

B01 Page 2 of 2 v1 Mar2025 between the southwest corner of the cemetery and Mint Spring Bayou project. The project consists of mobilization of construction crew, associated site work including minor clearing, erosion control measures and installing the wall drainage system per the site plans and specifications. Archaeological and cultural investigations will be conducted to monitor any ground disturbance and construction activities deemed necessary to protect archaeological resources.

The unique conditions that exist within the valley of Mint Spring Bayou have caused the bluff on which the National Cemetery is situated to slough off and erode. The southern brick wall around the cemetery and many other culturally sensitive components have already collapsed and fallen into Mint Spring. A project completed in 2011 consisted of the installation of two soil nail walls with shotcrete facing. At the base of the lower nail wall, the soil has become unstable and is sliding to the south causing movement of the Mint Spring Bayou bank.

Continued erosion and sliding of the soil at the base of the nail walls may eventually cause undercutting of the walls and eventual failure of the original project. The ongoing slide north of Mint Spring Bayou has forced the creek against the south bank, which in turn is causing the south bank to be undercut. As a result of this undercutting, a significant number of trees from the south bank have fallen across the creek. The collapsing soil above the creek on the south side shows signs of progressive failure over time. Unless the creek channel is stabilized, the south bank and slope above will continue to fail and could force the closure of the tour road through the cemetery and would leave no alternative route.
