Ann & Robert H. Lurie Children’s Hospital of Chicago

Chicago, Illinois

  • This complex 1.7-acre infill site for a hospital offered numerous unique characteristics, including a creative building geometry that encompassed 90% of the site, however 30% of the site was cantilevered to allow for an arching access drive through the site.

  • Site challenges included coordinating the location and elevation of the stormwater detention system, emergency generator fuel tanks and utilities to serve the hospital.

  • An existing 6.5-foot public sewer located adjacent to the property line resulted in approximately 28 feet of the eastern portion of the site having to be cut off by installing sheeting to safeguard the existing sewer line.

  • Ambulance bay placement necessitated re-striping and coordination of the signal timing.

  • Loading dock access is off of a newly dedicated Green Alley and public access among existing street networks and hospital structures.

  • Off-site road improvements included re-striping access and through lanes and relocating and upgrading crosswalks.

  • The project was awarded the LEED Silver Certification, and included water quality improvements through the use of a Stormceptor water quality unit.

  • Concrete was for paving to help reduce the heat island, non-roof effect. A green roof system decreased the heat island effect caused by the building and helped minimize stormwater runoff.

  • Extensive permits were required from the City’s Department of Water Management and Department of Transportation.
