GRPS C. A. Frost Middle/High - Boiler Replacement

Grand Rapids Public Schools is soliciting proposals for boiler replacement at C.A. Frost Environmental Science Middle High School, located at 1417 Covell Avenue NW, Grand Rapids, Michigan, with proposals due June 9, 2026 at 1:00 p.m.

The scope encompasses replacement of an existing Smith cast iron boiler (1,985 MBH output) with new boiler equipment (B-1, B-2, with provisions for future boiler B-3), new system pumps (P-3 and P-4 rated at 250 GPM each), a new hydraulic separator (HS-1), pressure relief valves (PRV-2 and PRV-3), a condensation neutralization tank (15 GPH), and associated piping and controls. The design includes elevated-pressure (.5 psig) natural gas piping with two new gas regulators, relocation of existing 3" hot water return piping, revised boiler stacks and combustion air routing with updated roof penetration locations, new 4" combination flow indicator and balance valves, new 6" concrete pad, new 8" stainless steel flue stack, and 8" PVC combustion air intake. Existing expansion tank and shot feeder are to be salvaged and reinstalled. Mechanical specifications and detailed floor plans are documented in the mechanical design drawings (M101, M102, M103) at scales of 3/8" = 1'-0" and 1/2" = 1'-0".

Addendum 1, issued June 2, 2026, revised the mechanical floor plans, boiler piping schematic, roof penetration locations, and the mechanical equipment list; no requests for information were submitted. WPF Engineering, LLC designed the project and retains all design rights. No contract value, term, or evaluation criteria are specified in the available source material.
