Minuteman National Historical Park Buttrick Roof R

The Department of the Interior National Park Service Northeast Region is soliciting proposals for comprehensive roof replacement services at two historic buildings within Minuteman National Historical Park in Concord, Massachusetts. The project involves completely replacing the existing roofs on the Buttrick Cottage House and Buttrick Carriage House with 3-tab asphalt shingles that will represent the presumed original slate material, including partial stucco stripping, flashing replacement, and installation of new copper gutters while maintaining the buildings' historic architectural characteristics. Contractors must provide all labor, materials, and equipment necessary to ensure a watertight roofing system that adheres to strict National Park Service guidelines for historical preservation. The contract will be evaluated using a Lowest Price Technically Acceptable source selection process, and proposals must be submitted electronically to Contracting Specialist Samuel McKenzie. A mandatory site visit was scheduled for July 18, 2025, at 174 Liberty Street in Concord, MA, with the proposal submission deadline extended to August 8, 2025, at 12:00 pm EDT through Amendment 0002.

This opportunity is specifically set aside for Service-Disabled Veteran-Owned Small Businesses, with an estimated contract value ranging between $100,000 and $250,000. The firm fixed-price contract requires contractors to begin work within 10 calendar days of receiving the notice to proceed and complete all work within 60 calendar days. The performance period is scheduled from October 1, 2025, to December 1, 2025, with daily work hours restricted to 7:00 am to 5:00 pm and no weekend work permitted. The contractor must maintain public safety and ensure park employee access throughout the construction period, as both buildings remain operational and are used daily by park staff. Work will be performed at 174 Liberty Street in Concord, Massachusetts, within the boundaries of the national historical park, with specific staging areas designated to minimize disruption to park operations.
