The University of Delaware has a network of underground steam and condensate piping serving their campus. Much of the piping is beyond its useful life and in need of replacement. DEDC, working with the University, developed an underground steam and condensate piping replacement master plan. We have been executing underground steam and condensate replacement over a series of years. Each section of replacement requires careful planning and coordination between the engineering and design team, piping fabricator and installing contractor. The coordination is required to minimize downtime as well as minimize the impact on the campus.
