12th Avenue Tunnel Project Completed!

As summer comes to an end, so does the construction on the OSU Wexner Medical Center 12th Avenue Tunnel project. Bruner was chosen to relocate the utility tunnel in order to provide high pressure steam and chilled water to the new Critical Cancer Tower along with distribution to other main hospitals on OSU’s Medical Center Campus. The new underground tunnel connects from the South Campus Chiller Plant and travels down Cannon Drive and up 12th Avenue to a main valve vault located at the corner of 12th Avenue and Harding Hospital. With the help of Bruner, this mechanical upgrade will result in greater efficiencies and savings in operational costs and energy in adjacent buildings.

Electrical, plumbing, and HVAC services were maintained throughout construction to major OSU buildings, and all piping systems were installed after the tunnel completion. So what was included you ask? For the chilled water piping there is: 1600 lineal ft of 36” and 900 lineal ft of 42” extra heavy carbon steel pipe, and 500 lineal ft of 24” pre-insulated underground piping. As for the high pressure steam and condensate piping: 1000 lineal ft of 12” seamless carbon steel piping and 1500 lineal feet of 8” and 6” stainless steel piping. Bruner manpower peaked at 20 pipefitters and welders at one time!

So the next time you are walking around Ohio State’s campus and find yourself on 12th Avenue, think about the hard work put in by Bruner to achieve efficiency and energy savings below you!
