The scope requires removal of existing Lochinvar KnightXL boilers (Model KBX-1000N-M13 in Building 2310 and Model KBX-0400N in Building 1610, or approved equal units) and installation of fully integrated replacement systems meeting specified salient characteristics: 7-inch touchscreen LCD display, 97% thermal efficiency, flow switch, condensate trap neutralizer, and 10:1 turndown modulating burner system. The contractor must furnish all labor, equipment, supervision, and materials; connect to existing electrical, water, and gas infrastructure; install isolation valves, tee connections, wye strainers, flow switches, and condensate neutralizer kits; provide BACnet (over IP) cards for Building Management Systems integration; insulate new piping; and program boilers to a 140-degree set-point with outdoor reset capability. Work is scheduled for late spring, summer, and/or early fall 2026, with all boilers required to be installed and functioning by October 2, 2026. The contractor must submit operation and maintenance manuals and manufacturer start-up performance sheet results (two copies). All contract personnel must be fluent in English, obtain base identification and vehicle passes, and wear distinctive company identification.

A final acceptance meeting demonstrating boiler operation is required prior to final inspection.
