Quadrangle Club

University of Chicago
Chicago, Illinois


Project Type: Higher Education

Project Size: 3 stories


The Quadrangle Club is a private club for the faculty and staff of the University of Chicago.  It is housed in a historic landmark facility originally designed by Howard Van Doren Shaw in 1922.  This National Register of Historic Places building houses an exclusive restaurant, hotel, and event spaces beloved by alumni and faculty.


After over ninety years of stress on the building envelope and leaking walls, the University selected the ZS team to design and oversee construction for a complete exterior façade rehabilitation and roofing replacement.  All phases of work were required to be completed during ongoing restaurant, hotel, and event space operations.  Due to the sensitive nature of construction project on an active site, ZS provided full-time Construction Observation services and around-the-clock coordination.  This project included full replacement of the graduated slate tile and membrane roofing systems, as well as 100% tuckpointing to all exterior masonry.


The University appointed the ZS team to perform a thorough condition survey of the building’s exterior brick/limestone façade and graduated slate roofs.  ZS developed remedial repair recommendations and probable construction costs to correct the existing deficiencies.  ZS prepared detailed design and bidding documents for the selected repairs, as well as a complete BIM model of the building envelope as part of the project’s historic preservation goals.

The ZS team provided Owner assistance services during the bidding process in accordance with University procedures and requirements.  This included Owner assistance throughout the construction process.  ZS completed daily observation reports to provide continual communication to the Owner during construction, allowing current updates on site progress and field decisions.  Project scope oversight included:

  • 100% tuckpointing to all exterior masonry
  • Total replacement of the graduated slate tile roofing system
  • Total replacement of the built-up membrane roofing system
  • Roof system  water testing procedures                                                         

The entire project was documented with Building Information Modeling (BIM) to provide an active model for the University.  This advanced record will allow future facility management staff to quickly access and utilize the integrated building model to quickly and accurately provide acute facility repairs, access warranty information, and reference historic material color matching.
