The City of Cambridge is seeking bids for a two-boiler replacement at Cambridgeport School, with related plumbing and electrical work.
- **Government buyer:** City of Cambridge — Purchasing/Awarding Authority, with Cambridge Public Schools as the school department; project location is Cambridgeport School, Cambridge, Massachusetts.
- **Scope:** Replace two existing boilers. Plumbing and electrical work are separate lump-sum filed sub-bids; the plumbing work is being solicited separately after the earlier sub-bid received no acceptable bids.
- **OEMs and named vendors:** **Lochinvar** is mentioned in connection with the boilers, but no boiler manufacturer is mandated. **Centrotherm** is mentioned as a potential exhaust vent and air-intake product supplier, not a required brand. **System Sensor** CO1224T is cited as the reference for the carbon monoxide detectors. Project and survey firms named are Johnson Roberts Associates, Inc. and Universal Environmental Consultants; Liz Unger is identified with City of Cambridge Purchasing.
- **Equipment and quantities:** Two boilers (B-1 and B-2); three VFDs for pumps P-1, P-2, and P-5; one glycol feed pump (GF-1); three hot-water pumps (P-1 through P-3); two boiler pumps (BP-1 and BP-2); one chemical-feed unit (CF-1); two carbon monoxide detectors; and two emergency boiler shutoffs. A new emergency panel (EPB) is also shown in the drawings. No required boiler model or part number is specified.
- **Notable requirements:** Boiler exhaust and air-intake products must be UL 1738-listed and included on the Massachusetts Accepted Plumbing Products approval list. Listed Massachusetts-approved press-type natural-gas fittings are acceptable. The CO detectors connect to the existing fire-alarm loop as supervisory-only devices; emergency shutoffs must interlock with the boiler controls and shut down both boilers. VFDs are required for P-1, P-2, and P-5, but not BP-1 or BP-2.
- **Site condition and participation:** The asbestos survey found chrysotile in roof-level boiler-exhaust components. Licensed asbestos abatement and project monitoring are required if asbestos-containing material is disturbed; hidden asbestos may also be encountered. The bid package states a goal of at least 10% MBE participation.
