Nearly 40 years after its construction, the grid-like concrete façade of 1240 North Lake Shore Drive was in need of maintenance. The 32-story building was designed in the early 1970s by notable mid-century architect John Macsai. Central was hired to remove and replace deteriorated concrete on all building facades and worked with a sub-contractor to recoat all exposed concrete on the building. The project began as a one year project to repair just the east façade, but a second phase was later added and the remaining three facades were repaired. Central worked with the building and their consultant to successfully control costs and complete a full restoration of the building within ownership’s budget.
