IVY Tower

City: Minneapolis

State: Minnesota

Owner: Ivy Tower Minneapolis, LLC

General Contractor: BOR-SON Construction, Inc

Project Description:

The historic Ivy Tower is the narrowest tower in Minneapolis, MN at just 50 ft x 55 ft in plan and 140 ft tall. Construction on the Hotel Ivy + Residence, which wraps around and incorporates the historic Ivy Tower, required a unique combination of earth retention and underpinning systems to allow a 51 ft deep excavation for five levels of underground parking directly adjacent to the historic Ivy Tower. The Ivy Tower was closely monitored for building movements throughout construction with satisfactory results.
