Tunnel Vision Underground utility upgrades help Big 10 university keep up with increasing demands by Jason Sweet “I t’s like spaghetti.” That’s how Ayres Associates project manager Kristine Anderson described the scene underneath the streets of the University of Wisconsin-Madison. Running on an annual budget of more than $2.7 billion, the University comprises around 42,500 students and nearly 16,000 faculty and other employees. Though it offers plenty of scenic lakeside vistas, the University’s location is hardly one of idyllic seclusion. Rather, the campus sits smack in the midst of Wisconsin’s capital city. That means a lot is packed in – and under – the 936 acres of the University’s main campus. To keep up with the demands of campus improvement projects, the University recognized the need to upgrade all existing campus utility distribution systems, which were operating at or near their capacity. This was particularly important for the East Campus Gateway and its proposed pedestrian mall, an extensive corridor that was decades in the making. At completion the mall would run past numerous new developments, including University Square, which consists of a nine-story, 237,000-square-foot Student Services Tower and an 850,000-square-foot, 12-story tower that includes rental apartments, retail space, and an underground parking structure. Developments like this made utility upgrades imperative. When it comes to a beautiful pedestrian mall meant to last far into the future, the last thing anyone wants is excavation in the area – the typical method to construct underground utility Top: A portion of the 1,800-foot-long underground utility tunnel installed at the University of Wisconsin-Madison.
