St. Ambrose University, Wellness and Recreation Center

Our investigation included visiting the project site to observe the existing structure and surveying the top and bottom floor slab surfaces to measure the concrete thickness and beam deflections. 

SGH reviewed the design assumptions and developed our own structural analysis model using information gained from the field investigation. Working with the original design team, we identified areas requiring strengthening or stiffening, and the project team implemented the repairs during construction.

To assess vibration concerns, SGH engaged a subconsultant to perform in situ testing to measure local structural frequencies and identify areas where the vibration exceeded industry recommendations. We collaborated with the design team to investigate mitigation options that would work with the project’s design and aesthetic requirements. By concealing four tuned mass dampers in the ceiling spaces, the team reduced vibration without affecting the structure’s appearance. Our work allowed the facility to achieve the university’s goals for opening the wellness and recreation center prior to students returning to campus in the fall.
