This project will replace the steam lines to Bldgs. 22, 12A and 12B. These lines have experienced multiple failures in recent years and visual examination of piping confirmed they need to be replaced. Replacement of the steam line should provide a new lifespan good for the next 40-50 years. This project also relocates a manhole to improve access and waterproofing and solves the problem of steam coming into Bldg. 12A when there is excessive ground moisture, such as after a heavy rain. ORF anticipates the project to be complete by April 2019. The sidewalk along Center Dr. will remain open during the duration of the construction. Those exiting Bldg. 12A near the construction site will, for safety reasons, encounter a slight detour around the work area.
