Statement of Work (SOW) Install Radon Mitigation in Casitas at Pecos National Historical Park

PART 1 – GENERAL

1.1 Background:

Pecos National Historical Park has a two-unit Casita for Transient and Seasonal Staff located at Forked Lightning Ranch. Radon tests conducted in November of 2024 showed 9.4 picocuries per liter (pCi/L), exceeding the Environmental Protection Agency (EPA) limit of 4.0 pCi/L for residential buildings. A radon mitigation system was installed around 2013, but it appears to not function as intended. This project is to modify existing system or install new systems to reduce the radon levels below 4.0 pCi/L.

The Casita is a 2,175 square, horse shoe shaped, foot block structure constructed around 1925. The current radon mitigation system is centrally located in the East Casita, plumbed into a crawl space and vented through the roof. Due to the historic nature of this structure, a design proposal for the mitigation will be required to be submitted to Pecos National Historical Park prior to work. Both exterior and interior visual appearances should be considered along with functionality. If old system is completely abandoned, it shall be removed and repairs made to both the foundation and roof. If old system is utilized a new fan shall be installed above the roof.

If horizontal boring and external mitigation systems are needed. Every effort should be made to install those systems on the north side of the casita to limit visual impacts. Other systems not envisioned in this scope will be considered and multiple systems may be required due to the shape and size of the building and a site visit is recommended.

Completion of the project will be determined when levels test below 4.0 pCi/L.

1.2 Work Covered by the Contract Documents:

• Project Location: Pecos National Historical Park, 1 Peach Drive, Pecos, NM 87552

• Scope of Work:

1. Conduct a site survey to assess the jobsite and existing system. See Attachments

2. Conduct baseline radon testing in both sides of the Casita.

3. Complete Pressure Field Extension Communication test to determine where Radon

Mitigation System(s) would be best located.

4. Submit design proposal to COR for approval keeping in mind historic nature of building.

Design proposal should include all components as well as new electrical locations.

5. If horizontal boring and external mitigation systems are needed. Every effort should be made to install those systems on the north side of the casita to limit visual impacts.
