Project Overview

Ideal Contracting served as the steel erector for the U of M Michigan Union project, which is a renovation of the historic student union building located in the heart of the U of M Ann Arbor campus. The building serves as the most popular gathering point for students, faculty, alumni, and guests.

The highlight of the newly renovated building is the year-round courtyard, which was enclosed with a new domed canopy consisting of HSS tube steel that Ideal Contracting proudly fabricated and erected. Due to the complexity of the work and tight fit-up tolerances, the modular HSS dome and built-up plate columns were fabricated and then fit up and mocked up by Ideal Contracting’s Ironworkers in our Detroit fabrication shop. The modules were then transported to the U of M Michigan Union site. A portable self-erecting crane, as well as a 265-ton hydraulic crane, were utilized to erect the AESS #3 finish canopy. With the help of engineering firm Ruby + Associates, the canopy was erected in sequences based on stability calculations until the main structure was completed.
