City Hall Chimney Repairs. Estimated Cost $50,000 work consists of removing the existing deteriorated clay tile lining of the flue gas chimney and relining with a stainless steel insulated liner, rebuilding the top portion and repointing the lower portion above the roof line, and related work. The project consists of the following work: Removal of the deteriorated/partially collapsed clay liner of the flue gas chimney. Installation of a stainless steel insulated liner. Rebuilding of the top portion of the chimney and repointing the remaining brick as necessary above the roof line. 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. Any questions regarding the bid need to be submitted in writing to Alan Twarog, Alan.Twarog@Greenfield-MA.gov by 10:00 AM Wednesday January 24, 2024. Upon further inspection, it has been determined that the entirety of the brick chimney will need to be rebuilt from approximately 4 feet below the roof line and up (approximately 20 feet). The flue from the boiler penetrates into the chimney about 18 inches and then turns 90 degrees and extends upward about 24 inches before transitioning to square brick. Approximately 6 to 7 feet of the old clay liner has been removed up from where the boiler flue ends. The remainder of the existing clay liner will need to be completely removed prior to installation of the new stainless steel liner. The existing IT equipment mounted to the side of the chimney shall be removed by the contractor and set aside for salvage by the City and shall not be re-mounted. Attached are photos documenting existing conditions.
