Performance Work Statement (PWS) De Soto National Memorial (DESO) Replace Replicated Palisade Fence

LOCATION: The location of this project for which these services will be utilized is within the De Soto National Memorial (DESO), a unit of the National Park Service. The address of De Soto National Memorial is 8300 Desoto Memorial Hwy, Bradenton, FL 34209.

REQUIREMENT: Contractor shall provide all labor, supervision, material, tools, equipment, supplies, transportation and incidentals necessary to remove the existing wooden palisade wall surrounding the interpretive Camp Uzita and replace the wooden palisade fence in kind, using cypress slabs for the facade and pressure treated lumber for the framing. The new structure shall remain in the same footprint as the original structure. The wall surrounding the interpretive camp measures 200’ in length and varies from 4’-13’ tall sections. There is a 60’ long entryway wall, separate from the camp wall that shall be included in this project. Where visible to the public (approximately 140’ of the total 260’) the wall has cypress slabs attached to both sides of the framing to conceal it. Along the mangrove swamp, where only one side is visible, there is cypress attached on only the interior side visible to the public.

There are two doorways built into the wall. One door is a framed 3’ by 6.5’ entryway and another is a 4’ entryway that extends to the top of the 13’ wall. The larger opening, when replaced, shall match the dimensions of the smaller opening. There is a PT deck area built behind the smaller doorway that measures 6’ by 10’ with a small bench and outdoor sink, this shall remain. Water supply to that sink shall be capped off at that location, making sink inoperable. In addition, there is a PT wood shed located behind a section of the wall that shall be removed and not replaced. The shed measures 4’ by 5’ and is 8’ high. A framed opening shall be added to the north side and south side of the palisade wall to increase air flow within the camp. It shall measure at least 3’ tall and 5’ wide and be covered with cypress slabs to conceal the opening when not being used. They shall open outward and be able to be propped open by staff. All pre-existing electrical and water supply lines shall be removed and secured before demolition, then re-assembled, and made operational following completion of the project. The contractor shall install measures to protect the adjacent mangrove swamp from debris and damage.

Existing Conditions: The deteriorated wooden Palisade Wall at Camp Uzita at De Soto National Memorial is a replica of an early Spanish fort. It is made to appear as if small whole cypress trunks are enclosing our multiple interpretative structures. In reality, it is first cut slab cypress (with bark) mounted on a pressure treated wood frame. Electricity, water and rest room facilities are available on site.
