University of Michigan Utility Tunnel System Repairs

University of Michigan

The University of Michigan engaged Commonwealth to perform structural engineering design and provide construction administration services to repair and upgrade sections of the University’s extensive utility tunnel system.  Commonwealth provided specialty interior concrete restoration and crack injection design within nine distinct sections of tunnel comprising over 3000 linear feet of tunnel, as identified in a prior system-wide condition assessment to extend useful life of the University’s infrastructure.

The project design process involved site investigation of the tunnel sections to perform visual observations, evaluate the existing conditions, design specialized repairs and assist the University to prioritize repairs to meet budget limitations. Commonwealth prepared construction documents including drawings and specifications. Commonwealth provided a cost estimate to guide the project strategy for bidding, schedule, and budgetary purposes. Commonwealth subsequently performed services as the University’s field engineer to assist the contractor and monitor construction progress to help bring about a successful project within the budget and schedule constraints.
