Scope

This scope of work will focus on repairing and restoring approximately two thousand two hundred (2,200) square feet (six hundred (600) feet in length) dry stack stone wall at

Cragfont State Historic Site. The goal is to restore, repair, and reconstruct the wall across the entire length of the structure to an average height of three and one half (3.5) feet, including the copestones.

Contractor shall do all the following without exception:

1. Initial Assessment and Documentation:

• Perform a thorough evaluation of the dry stack stone wall to determine and document all existing conditions, necessary repairs, and specific restoration requirements for the sashes, frames, and associated millwork.

• Photograph the stone wall in a manner to assist with reconstruction.

2. Careful Disassembly:

• In fifty (50) foot sections at a time, dismantle the stonework of the wall.

• After dismantling each section, remove all Portland cement or other modern materials used to temporarily repair sections of the wall in the past.

• Evaluate available stone to reuse and document where additional will be needed to replace cracked and unusable stones.

3. Reconstructing the dry stack stone wall

• Using the photographic evidence required in the documentation phase, reconstruct the dry stack stone wall in fifty (50) foot sections based on the design and layout of how it was previously constructed, including the copestones.

• The reconstruction process shall use all salvageable stones from the original wall first.

- Contractor is responsible for sourcing all additional stone required to reconstruct the wall. This price shall be included in the quote and an approval by site director and program coordinator is required before agreeing on new stone being suggested.

- Slight changes to the original design are permitted based on stones available, trees surrounding the wall, gates, and the new request to adhere to a three and one half (3.5) foot height across the length of the wall. Significant changes are required to be brought to program coordinator and site director for approval.

4. Quality Check:

• When at least three (3) sections of fifty (50) foot wall are restored, a check in with the site director and program coordinator is required for quality assurance and design approval.
