An excavator tears up a walkway on the southeast side of campus, causing pedestrians to take a detour. Part of Lane’s $83 million bond that helped with the Center Building remodel is also being used to improve the infrastructure behind the scenes. Currently, Lane is finishing up a three-step project to fully replace boilers, cooling towers and chillers. The new enclosure that is currently being built north of Public Safety replaces the chillers formerly in Building 12. Regulations and codes have changed since the chillers were installed nearly 40 years ago. “You can not have boilers and chillers in the same room anymore,” Troy Hanson, project coordinator for Facilities Management and Planning, said. The project should be complete by June and fully functional by mid-summer.
