Renovation of a municipal facility in Greenfield, Massachusetts. Completed plans call for the renovation of a municipal facility.

Soliciting bids to reline the flue gas chimney at City Hall located at 14 Court Square in Greenfield, MA. The brick chimney is also in various stages of deterioration requiring the top of the chimney to be rebuilt and lower portions repointed. The existing clay tile lining inside the chimney has partially collapsed and will need to be removed before a new liner is installed. The chimney at City Hall serves to remove flue gasses from a natural gas fired steam boiler. Moisture and flue gasses in the range of 300-500 degrees F have deteriorated the original clay tile liner to the point that it has partially collapsed inside the chimney. As well, constant expansion and contraction has caused mortar joints to fail on the chimney itself. The work consists of total removal of any remaining clay liner and replacement with a 316T stainless steel insulated liner, complete with 20 gauge 316 stainless steel crown chase cover and rain cap to prevent further water infiltration. The transition section joining liner to boiler flue box shall be a custom 20 gauge stainless steel tee section with condensation drain and supports. The proposal shall include rebuilding the top portion of the chimney and repointing the remaining brick as necessary above the roof line. Mortar used for repointing shall be Type O mortar conforming to ASTM C 270. If it is determined that the present condition of the chimney warrants a total rebuild above the roof line, the Contractor will quote this as a separate price Any questions regarding the bid need to be submitted in writing to Laura Phelps, Laura.Phelps@Greenfield-MA.gov by 10:00 AM Wednesday August 30, 2023.
