• Project Name: OSU Steam and Condensate Distribution System Upgrades Phases 1-4
• Location: Columbus, OH
• Client: The Ohio State University
• Industry: Institutional
• Size: Approx. $6.3 Million

Project Description: This complex, multi-phased project included BIM modeling, prefabrication and field installation of new 16″ 300 psi steam piping and 8″ 200psi condensate piping.  The project spanned multiple school years and Ohio State Football seasons.  The new piping began at tie-ins to existing services inside of McCracken Power Plant.  They were routed above grade through an existing fuel-oil tank farm & containment dyke, then transitioned underground and ran around much of the outside of Ohio Stadium (“the shoe”). The piping included several new steam vaults ranging in depth from 10′ to 25′ deep; it traversed multiple street crossings which were both open cut and tunneled and connected to multiple buildings throughout campus. The work was carefully scheduled so that major tie-ins and shut-downs affecting occupied buildings could be done during milder temperatures and so that underground installations and street closings were coordinated around home football games and even a visit from the President of the United States. This work was contracted in 4- separate bid packages and MIELKE was the only major contractor to be awarded all 4- phases of this project.
