Alberici served as the design-build contractor for the 25-story Roberts Tower building, the first new high-rise residential construction in downtown St. Louis in over 40 years. Lower floors in this mixed-use tower include restaurant and commercial space, as well as a conference addition for the adjacent Magnolia Hotel St. Louis. The remaining floors feature 128 luxury apartment units.

Complex logistics on a tight urban site

With existing structures on three sides, there was only one point of access. Alberici’s careful planning and stringent adherence to procedures enabled efficient construction despite the tight site in a densely-populated commercial and residential area.

Preexisting foundations and utility lines posed threats to worker safety and the schedule. Alberici implemented a stone-cutting technique normally associated with quarry work to safely remove a shared foundation with the adjacent Magnolia Hotel.
