About this file

Written by GovTribe AI · Aug 17, 2026

This file consists of mechanical drawings and specifications for a boiler replacement project at the Barnum Museum located at 820 Main Street, Bridgeport, Connecticut, prepared by Antinozzi Associates, P.C. for the City of Bridgeport. The primary scope of work involves the replacement of existing hot water boilers with new condensing hot water boilers, removal of existing hydronic equipment from the basement, and installation of new hot water piping, boiler pumps, expansion tanks, air separators, and associated valves and controls. The contractor is responsible for complete demolition of existing equipment, installation of new condensing gas boilers, plumbing modifications for natural gas piping, combustion air piping and venting systems, hot water piping insulation, electrical work to support new mechanical equipment, integration into the building automation system, system startup with manufacturer support, hydrostatic testing, water testing and balancing, and submission of shop drawings and as-built documentation. The project includes four hours of owner training on the new mechanical equipment and controls. Electronic bid submissions are due by 2:00 pm on Friday, September 11, 2026, through the City's OpenGov e-Procurement portal, with the question cutoff date set for 5:00 pm on Thursday, August 27, 2026.

The specifications detail equipment requirements including condensing gas boilers meeting ASME "H" stamp certification and 97% minimum combustion and thermal efficiency, with manufacturers identified as Lochinvar, Peter and Kelly, Burnham, or Patterson-Kelly. Circulation pumps are specified as ECOcirc XL models or equivalents from B&G, Taco, or Grundfos, featuring integrated variable frequency drives and modbus or bacnet communication protocols. The project requires expansion tanks rated for 150 PSI working pressure, positive pressure venting systems constructed of flame-resistant polypropylene, and comprehensive piping in copper and black steel with appropriate fittings and insulation. All work must comply with state and local codes, NFPA standards, ASHRAE 90.1 energy efficiency requirements, and industry standards including AABC and NEBB. The contractor must obtain all necessary licenses and permits, conduct site visits prior to bidding, perform hydrostatic testing at 125 PSI minimum, and provide testing, adjusting, and balancing services by AABC or NEBB-licensed contractors within plus or minus 10% of design specifications. All equipment carries a one-year warranty, with the boiler heat exchanger assembly carrying a ten-year limited warranty.
