1 N. LaSalle
ONL Properties and MBRE engaged BEAR to build a terrace on the 25th floor of their 1 N. LaSalle building, Chicago. Built in 1929, existing structural drawings were inadequate to determine if the roof could support the new amenity. Four weeks of working nights in occupied spaces, exposing and scanning steel members, concluded that 2 feet of lightweight concrete topping had to be removed for the terrace to be constructed. Partners By Design was the architect. Project Manager Jarrik Mitchell and Superintendent Dan Sweeney managed the project for BEAR.
