About this file
The document is a Statement of Work (SOW) Attachment C - 15% Concept Demolition Plan for a mechanical room renovation project. The plan details comprehensive demolition requirements for existing mechanical systems, including:
Specific demolition tasks include removing abandoned steam piping, steam accessories, domestic cold water (DCW), domestic hot water (DHW), and related infrastructure. The plan involves removing existing boilers, gas piping, water heaters, circulation pumps, and associated electrical services. The scope requires complete removal of glycol feeder tank systems, gas meters, and various piping systems back to specified points of connection. The demolition is part of a broader mechanical room upgrade, with provisions for potential reuse of some existing components like water heater flue exhaust pipes, contingent on their condition. The document is part of the FY25 Multiple Award Construction Contract (MACC) for Fairchild Air Force Base in Washington, covering facility maintenance and renovation work.

This drawing does not represent the current as-built status of the MER. Steam heating system has been replaced by boiler and hydronic heating accessories and water heater has been replaced. Many steam components have been abandoned in place to make space for the existing boiler, which replaced the steam heating system.
MAU is not shown but has been approximated for location. Field measurements will be required for ROM piping calculations (demo and new). Only ROM concept plan has been shown and not piping length approximations.
Area well approximately 15 feet below grade -existing boiler and water heater combustion air, and boiler and water heater flue exhaust located here
Remove all leftover abandoned steam piping and steam accessories - see SOW for approximate quantities, but KTR is responsible to bid based on their observations / measurements
Completely remove DCW, DHW, DRHW piping systems, including water heaters, storage tanks, circulation pumps, mixing valves, expansion tanks, combustion air piping, gas piping, gas regulators, gas regulator vents, etc., back to MER entrance near interior door. This includes recirculation piping back to the MER interior door. Electrical service to domestic service equipment shall be removed and new service re-installed to new equipment (water heater, circulation pumps, disconnects, etc.).
DCW
Remove existing boiler, gas piping back to gas meter (outside), HWS piping back to air separator, HWR piping to location shown, combustion air and flue exhaust piping, muffler
(DEMO - 15% CONCEPT)
Make-Up Air unit (remains) -approximate location. Removal of fan motor may be necessary to bring new equipment into MER.
DCW service entry
Remove (E) 2-inch gas line serving boiler from meter outside - see Page 2
Cap this gas line at wall/ceiling
Existing electrical Panel M to remain
Water heater flue exhaust pipe (metal) - Design team may re-use if functional and uncompromised; otherwise, remove water heater flue exhaust and route new water heater flue exhaust through mechanical area well. If cannot re-use, cap at mechanical room ceiling and at exterior termination.
(ABANDONED)
Existing switchboard
Remove glycol feeder tank system, including all piping back to POC on HWR and CHWR pipe
