ZS was selected by Crescent Heights of America to provide exterior building maintenance access and fall protection consulting services for what will become the tallest building in Chicago’s South Loop. The 892-feet tall skyscraper designed by Rafael Vinoly Architects is the first of three planned projects that Crescent Heights plans to develop on the corner of Michigan Avenue and Roosevelt Road.

The staggered tier design of the building along with the overall height poses a great challenge in designing the maintenance access solution.  ZS access solutions for this skyscraper included a custom Building Maintenance Unit (BMU) at the top of the building. ZS also designed access for the multiple green roofs of the new building. The unique beauty that comes from having green roofs on top of a building also requires forethought to ensure that the plants and trees on the roofs can be accessed safely for maintenance. During construction ZS will be onsite to provide construction observation services for all maintenance access systems.
