About this file
This file consists of technical engineering drawings and specifications for a boiler replacement project at Meriden Fire Station #5, located at 1075 East Main Street in Meriden, Connecticut, prepared by Bemis Associates LLC. The project involves comprehensive replacement of the existing heating system with a new gas-fired condensing boiler (Lochinvar Knight XL Model FTXL1000N-120), including mechanical, electrical, and plumbing demolition and installation work. The scope encompasses removal of the existing boiler, associated piping, valves, and related equipment; installation of new piping with proper insulation; replacement of the expansion tank, air separator, and circulating pumps; installation of a new indirect water heater; and all necessary electrical work including new wiring, disconnects, and controls. The drawings detail boiler room mechanical and electrical demolition and new work, mechanical details with schematic piping diagrams, equipment specifications, and installation details for combustion air intake, venting, condensate drainage, and pump installations. Key specifications include a Lochinvar commercial reverse indirect water heater (Model STU150, 125 gallons), an ITT Bell & Gossett expansion tank (Model D-60V, 33.6 gallons), and an ITT Bell & Gossett air separator (Model R-3F). The contractor is responsible for all temporary domestic hot water provisions during construction, field verification of existing conditions, coordination with other trades, and maintenance of building occupancy throughout the project.
The drawings emphasize that contractors must conduct mandatory site inspections prior to bidding to identify existing conditions and document baseline system measurements, including heating system pump flow and head pressure. All demolition material must be removed from the site unless otherwise noted. The contractor must coordinate with existing systems and utilities, including electrical, sewer, water, and gas lines, and is responsible for locating, identifying, protecting, and repairing any damage to existing utilities encountered during work. The specifications reference compliance with the 2022 Connecticut State Building Code, applicable NFPA codes, the National Electrical Code, and ASME Boiler and Pressure Vessel Code standards. The project includes an 18-month guarantee period from acceptance date, during which defective materials or workmanship must be repaired or replaced at no cost to the city. Prevailing wage rates apply to the project, with rates ranging from $21.42 to $66.72 depending on worker classification. Liquidated damages are assessed at $250 per calendar day for failure to meet completion deadlines, and a mandatory site inspection was scheduled for November 19, 2025, with sealed electronic bids due by December 10, 2025, at 11:00 a.m. through the City eProcurement Portal.
