About this file

This is a Request for Information (RFI) document for solicitation 127EAX26Q0046, addressing clarifications on foundation and masonry repair work for historic cabins within the Custer-Gallatin National Forest. The RFI responses provide technical guidance on two specific project locations: the Fourmile Cabin and the Ibex Cabin. For the Fourmile Cabin, responses clarify that the new concrete footer must be positioned a minimum of 4 inches below finished existing grade and maintain a minimum thickness of 6 inches, with exact depth varying based on existing rock facade depth. The existing cabin wall is believed to sit on a stem wall with no foundational support under the rock facade. Frost concerns are to be addressed through compacted drain rock around the footer and proper slope drainage away from the cabin. For the Ibex Cabin, vertical crack repairs involving removal and rebuilding of 2-3 foot sections may require excavation to footing depth or until mortar joints are no longer damaged; exact foundation depth is not currently known.

The RFI also provides guidance for contractor site visits: while the cabins are typically rented to the public and privacy must be respected during occupied periods, the cabins are closed through September and contractors are encouraged to visit during this timeframe to assess work requirements. Contractors must notify Logan Foster (logan.foster@usda.gov) of intended visit dates so district office personnel can be made aware. This work is being performed under the Department of Agriculture Forest Service and must comply with national standards for historic property repairs, as reflected in the related solicitation amendment posted July 13, 2026.

GAOA Certified Historic Masonry Work Custer-Gallatin National Forest

RFI#1-Please confirm top of new footer is 4" below grade for the Fourmile cabin?

· Top of the footer will vary as the rock façade progresses along the cabin foundation. The footer will need to be a minimum 4” below finished existing grade, but may be more depending on the depth of the existing rock façade. Exact depth of footer is determined by the depth of the existing façade depth. Minimum thickness of the footer will be 6”.

RFI#2-Please confirm new concrete footer is 6" in depth for the Fourmile cabin?

· See RFI#1 answer. Footer to be 6” thick minimum.

RFI#3-What does the existing wall sit on now for the Fourmile cabin?

· Existing cabin wall is believed to sit on a stem wall at the Fourmile Cabin. The rock façade has no existing foundational support.

RFI#4-Frost depth as drawn will be well below footer depth as drawn, is this not a concern for the Fourmile cabin?

· Compacted drain rock around the footer and sloping away from the cabin should alleviate a majority of the frost concerns.

RFI#5-What will prevent frost from lifting footer and new wall at the Fourmile cabin?

· See RFI#4 Answer

RFI#6-Ibex Cabin calls for vertical cracks to be repaired with 2-3 ft section to be removed and rebuilt. Is the depth of the foundation known?

· Exact depth of the foundation is not known.

RFI#7-Does this 2-3 ft section require excavating to footer for the Ibex Cabin?

· Yes, excavation may be required to the footing depth or to where the mortar joints are no longer damaged.

RFI#8- Are contractors allowed to drive to the work location to see the degree of work needed?

· These cabins are typically rented out to the public, and if they are occupied, we need to respect the renter’s privacy and not visit the cabins. That being said, the cabins are currently closed thru September. If you would like to visit the work locations during this time, that would be encouraged. Please let Logan Foster know the days you’ll be visiting so the appropriate people at the district office can be made aware. (Email: logan.foster@usda.gov)
