The National Park Service, Contracting Operations East, New England Major Acquisition Buying Office, has issued Request for Proposal (RFP) 140P4326R0039 for domestic water improvements at Minute Man National Historical Park in Concord, Massachusetts. This total small business set-aside construction requirement entails installing a new domestic water line at the Inferrera House (CLIN 00010), drilling a new well at the Rego House (CLIN 00020), and a unilateral option to remove a field valve and cap the water main (CLIN 00030). The contractor is required to furnish all labor, supervision, materials, tools, and professional services necessary to complete the project. An organized site visit is scheduled for September 2, 2026, with proposals due by September 9, 2026. The performance period is designated as 240 calendar days from the issuance of the Notice to Proceed, which must commence within 14 days of receipt. Administered via electronic invoicing through the Internet Payment Platform (IPP), the contract incorporates standard Federal Acquisition Regulations (FAR) and Department of the Interior clauses, including requirements for System for Award Management (SAM) maintenance, executive compensation reporting, and subcontractor disclosures. This project highlights the National Park Service's ongoing efforts to maintain and modernize park facilities and infrastructure.

This federal construction document outlines the site layouts, scope of work, and engineering plans for the Domestic Water Improvements project at Minute Man National Historical Park in Middlesex County, Massachusetts (NPS PMIS No. 317529). The project spans two locations: the Inferrera House (Concord, MA) and the Rego House (Lincoln, MA), and involves decommissioning existing domestic wells and installing a new water service infrastructure. For the Inferrera House base bid, the contractor must decommission the existing well and install a new 2-inch HDPE waterline via 700 linear feet of trenching, including horizontal directional boring under Lexington Road. This requires close coordination with MassDOT and the Town of Lincoln Water Department to establish a new municipal water connection and meter pit. An alternative option involves drilling a new well with water treatment, or capping the old service back to the main. For the Rego House base bid, the scope includes decommissioning the existing well, drilling a new 500-foot-deep, 6-inch domestic well with a 1/2 HP submersible pump, and installing a 32-gallon pressure tank and 60 linear feet of waterline connected to the existing filtration system. The plans include detailed septic system design references, soil profile data from test pits, and regulatory guidelines. The contractor is responsible for obtaining all permits, calling DigSafe, maintaining utility clearances, and restoring all disturbed landscapes and pavements to their original conditions.

This document outlines a government wage determination schedule, which establishes prevailing wage rates and classifications required for federally funded or assisted construction projects.
