University of Michigan Eye Center
Ann Arbor, Michigan
The University of Michigan proposed a $132,000,000 expansion of their eye center, consisting of a 12-story addition to the existing eye center building. TEC was retained to provide a comprehensive geotechnical investigation and engineering recommendations.
Due to multiple site constraints including a zero lot line, it required temporary earth retention along the street to the south which needed to remain open for fire access. TEC designed a retention system and reviewed subsequent design by the contractor. TEC also designed a drainage system and prepared specification sections when the basement was still part of the design. TEC provided recommendations to prevent damage to underground utilities and ensure a stable crane foundation. TEC was also retained to provide construction materials testing and quality control during construction. Services included, foundation bearing capacity verification, earth retention installation observation, backfill density testing, concrete testing and structural steel inspection. TEC performed the geotechnical field work on the weekends so as not to disrupt patient parking.
