The Residences at The St. Regis Chicago

This guide to The Residences at The St. Regis Chicago follows Shelby Griffin, a young civil engineer who spent two and a half years riding a construction elevator toward the sky as the tower's concrete rose one floor every three days. It traces the other women who ran this job site alongside her, a residential build manager, a safety manager who started as a flagger, and the construction firm's first female leader, on a tower designed by architect Jeanne Gang. Listen for how unusual that lineup was against the numbers for the industry as a whole.
