Gate-repair FT. Tompkins earthen roof

The National Park Service Northeast Region is seeking a contractor to perform comprehensive repair and restoration work on the Fort Tompkins Earthen Roof Structure at Gateway National Recreation Area in Staten Island, New York. This historic preservation project involves rehabilitating a section of the earthen-filled roof dating to the 1850s, with the primary objective of addressing ongoing water infiltration issues and protecting the historic resource from further deterioration. The scope includes archaeological monitoring, hand excavation of earthen fill, masonry structure repair, waterproofing installation, drainage system replacement, and restoration of the vegetated roof surface. Contractors will be evaluated using a best value tradeoff process across four factors: Technical Approach and Schedule, Management Approach, Past Experience, and Past Performance, with non-price evaluation factors being approximately equal to price. The solicitation deadline has been extended to August 25, 2025, with a mandatory site visit having occurred on August 1, 2025.

This opportunity is 100% set aside for small business concerns under NAICS code 238910 for Foundation, Structure, and Building Exterior Contractors. The contract value is estimated between $1,000,000 and $5,000,000, structured as a firm fixed-price contract with a base line item for earthen roof restoration and three optional probe investigations (Options A, B, and C). The performance period runs from April 1, 2025, to March 31, 2026, with contractors required to commence work within 10 calendar days of receiving the notice to proceed and complete all work within 365 calendar days. Work will be performed at the historic Fort Tompkins site within Gateway National Recreation Area on Staten Island, requiring specialized historic preservation techniques and compliance with archaeological monitoring requirements. The project operates under Davis-Bacon wage determination requirements for New York State construction work, with specific considerations for working within a sensitive historic and archaeological site that remains open to park visitors.
