About this file
This Scope of Work (SOW) details a wildlife-friendly fence installation project for the O'Farrell Waterfowl Production Area in Grant County, South Dakota. The project involves removing approximately 9,400 feet of existing 3-strand barbed wire fence and replacing it with a 4-strand wildlife-friendly fence designed to protect livestock and property while minimizing wildlife impact. Specific requirements include a total fence height of 42 inches, wire placement at precise heights (16-18 inches for bottom smooth wire, up to 42 inches for top wire), and using 12.5 gauge galvanized barbed and smooth wire.
The project is scheduled to start no earlier than October 1st, 2025, and must be completed by September 30th, 2026. Key specifications include using a mix of steel T-posts and treated wood posts, installing 12-16 ft gates, and ensuring wildlife accommodations such as bottom smooth wire and avoiding known wildlife corridors. Environmental considerations mandate limiting machinery to designated paths, avoiding wetland disturbances, and maintaining erosion control. Deliverables include a completed fence meeting all specifications, a final walk-through with the project manager, and an as-built map showing fence alignment and gate locations. The project is managed by Bryce Ahlers, Refuge Manager, and requires strict compliance with OSHA and local safety regulations.

Scope of Work (SOW): Installation of Wildlife-Friendly 4-Strand Barbed Wire Fence Installation And The Removal Of The Existing Fence.
Project Title
Wildlife-Friendly 4-Strand Barbed Wire Fence Installation and the removal of the existing fence
Location
121N-50W- 31
Grant County, SD
O’Farrell Waterfowl Production Area
Project Summary
The purpose of this project is to remove and install approximately 9,400 feet of wildlife-friendly 4-strand barbed wire fence to protect [livestock/crops/property boundary] while minimizing impacts on local wildlife. The fence will be constructed to standard specifications that allow for safe passage of species such as deer and pronghorn while maintaining livestock control. The existing fence will be removed and replaced with new fence. The existing fence consists of all steel posts and 3 strands of barbed wire, except for the wood H- Braces and Corner Braces. The disposal of the current dilapidated fence will occur offsite and will be the responsibility of the contractor.
Objectives
- Remove all existing fence in the project area where the new fence will be installed
- Install a secure, durable 4-strand barbed wire fence.
- Incorporate wildlife-friendly design specifications.
- Minimize ground disturbance and habitat fragmentation.
- Ensure compliance with applicable local/state regulations and conservation practices.
