About this file
This is a Building Inspection Deficiencies Report dated December 2025 for Boston National Historical Park's fire sprinkler systems across ten buildings requiring comprehensive repairs and upgrades to achieve compliance with NFPA 25-2014 and NFPA 25-2026 standards.
The report identifies deficiencies across multiple facility locations: Building 4&5 (Visitors Center & Navy Barracks/Office), Building I (Marine Barracks/Administrative Office), Quarters G (Commandants House), Bunker Hill Museum, Building 109 (Interpretation & Protection), Building 24 (Navy Maintenance Offices), Building 125 (DC Bean), Building 32 (Marine Society), Building 10 (Shipyard Galley), and Building 107 (Yard Maintenance). Required work includes hydrostatic testing of fire department connection piping at 150 psi for 2 hours (mandatory every 5 years), replacement of 1,059 total sprinkler heads (primarily old upright models in service 75+ years), replacement of 28 escutcheons and coverplates, replacement of multiple flow switches (4-inch and 6-inch sizes) that failed semiannual testing, installation of visible FDC signage at multiple locations, placement of hydraulic placards on standpipes, replacement of damaged control valves and angle valves, installation of electric bells to replace inoperative water motor gongs, air leakage testing of dry systems, addition of check valves to trim lines, installation of inspector test connections, and repair or replacement of butterfly valve supervisory alarm devices. Work is required across multiple valve sizes (1-inch, 1.25-inch, 2-inch) and piping configurations to ensure all systems function within regulatory requirements.
