The purpose of this project is to replace the aging Steam-line Expansion Joints (A-Line) in the Y Tunnel, which was built in the early 1930s and supplies steam and chilled water service to various jurisdictions. The A-Line is around 3,300 linear feet long. The project involves replacing the aging Steam-line Expansions Joints (A-Line) located in the Y Tunnel. The scope includes: Removing the aging steam line expansion joints. Installing new expansion joints on the high-pressure steam line. Repairing, removing, replacing, or updating structural pipe supports at discrete locations. Performing any associated concrete work (walls, ceilings, or floors) where pipe supports and other structural steel supporting the steam line infrastructure is embedded. Removal of existing expansion joints ( around 25-27) on high pressure steam lines between stations 0+00 and 29+50 on 14” Dia steam lines .
