University of Michigan Clinical Inpatient Tower Building Auxiliary Engineering Services and Tunnel Upgrade

University of Michigan

The University of Michigan (U of M) has begun preliminary planning for the new Clinical Inpatient Tower (CIT) building and all associated site/infrastructure work, including new utility tunnels and new site/infrastructure utilities. Commonwealth is providing auxiliary engineering design services to plan for temporary utilities and a utility bypass in support of the logistical planning and phasing of the new project. The auxiliary engineering services involve conceptual planning to temporarily route steam and other utilities critical to the operation of the U of M Medical Campus facilities as well as planning for supplemental steam supply to certain facilities. Multiple options for utility routing and providing supplemental steam were considered and evaluated, supported by logistical and cost analysis.

In a related but separate project at U of M’s Medical Campus, Commonwealth is performing engineering and design services in support of a multifaceted utility tunnel project along the north side of Catherine Street between Glen Avenue and Zina Pitcher Place. The purpose of this project is to upgrade, improve and extend the life of U of M’s critical infrastructure, including the tunnel structure and utility systems. Commonwealth also performed mechanical engineering and design to evaluate options for additional steam supply to the Medical Campus and perform the design for the selected option. This design involves piping design and stress analysis, routing, planning for construction sequence, outages and re-connections to existing facilities, and relocating other utilities in the tunnel system to provide the new utility configuration.

The utility tunnel structural upgrade project scope includes reinforcement of specific segments of an existing cast in place concrete tunnel. Commonwealth designed the tunnel reinforcing and improvements necessary for heavy vehicle loading including firetruck access and other construction vehicles. The project also involved a structural condition assessment, localized repairs and waterproofing measures, all to improve the condition of the tunnel system and extend the life of U of M’s critical infrastructure.
