In the fall of 2007 Jacobs/ Ryan Associates was asked to consult with Valerio Dewalt Train Architects for the installation of a green roof on the third floor of the Apparel Center, which is located across the street from the Merchandise Mart. This project presented a number of challenges including an accelerated project design to completion time frame with the Green Build Conference scheduled in Chicago in November.

Additionally, it was determined the existing membrane roof was leaking and required repair. Therefore, C.E. Crowley and Associates, Inc., a roofing and waterproofing consultant, was hired to make the necessary roof repairs before the green roof system could be installed.

Jacobs Ryan Associates collaborated with the architect to develop a design solution featuring serpentine curves which mimicked the organic nature of the Chicago River and encompassed over 10,000 square feet of green roof. Since the project was so time sensitive, the design team elected to use a 4" built up green roof system with a pre-vegetative mat for an immediate impact. JRA coordinated the green roof implementation with the installing contractor, Intrinsic Landscaping, and the provider of the growing media, Green Roof Solutions. The pre-vegetated mat was installed in two days resulting in an instant green roof completed just in time for former President Bill Clinton to see as part of his Green Build pre-conference tour.
