This summer, Physical Plant-Facilities is overseeing the installation of steam and condensate return piping from Olin Library to the Freeman Athletic Center. The route runs along an underground tunnel between Olin and Clark Hall to the intersection of Pine and Church Streets, then through the backyards between Pine and Fountain Avenue, across Fountain, across Warren Street and due south along Warren into Freeman. The run is about 2,000 feet long.Physical Plant bid the project in late 2013 and purchased the pipe in early 2014. The pipe is manufactured by Perma-Pipe Systems and is welded and insulated at each joint with a closure jacket of insulation. Installation of the steam and condensate return pipe began on May 27. Installation from Olin to the corner of Pine and Church will be complete by June 12 with work in Church Street estimated to begin on June 16.
