University of Iowa Court Street Utility

Challenge

In 2008, historic floods destroyed the Voxman Music building on the University of Iowa (UI) campus. An 80,000-square-foot replacement facility was designed at a new location several blocks away from the university-owned utilities that would serve the building. The design had to include meeting the needs of the new School of Music building, public right-of-way requirements and utility design standards.

Solution

Planning for the utility extensions involved collaborating with the UI Utility and Energy Management staff on preparing routing studies, modeling multiple utility sizes and providing anticipated cost opinions.

The construction of utility corridors had to be near or within a public right-of-way. This required coordination of traffic flow including site and delivery access and pedestrian traffic; gas powered backup boiler equipment for the high pressure steam and gas service.

MUTCD (Manual on Uniform Traffic Control Device) traffic control plans, site restoration and grading and ADAAG (ADA Accessibility Guidelines) sidewalk upgrades were provided for full street replacement. Parking lot restoration and retaining wall modifications provided infrastructure for the boilers for emergency steam. Additionally the steam vaults, ventilation, pumps, and electrical services required electrical, mechanical and structural engineering.

Utility extensions included 12-inch domestic and chilled water; 4-inch condensate and 12-inch low pressure direct buried Perma-pipe steam piping; new utilities to operate the backup boilers: 14-inch high pressure steam; epoxy lined sanitary waste line and 6-inch water service; multi-cell high voltage electrical duct bank; sanitary sewer services and 18-inch storm sewer upgrades.

Impact

The utility extension was completed on schedule so a high-traffic street could be re-opened to the public. The university accomplished its goal for the new School of Music building to be served by its university-owned utilities.
