RRJ designs 9/11 Memorial for Village of Willowbrook, Illinois

RRJ provided structural engineering services for the design of a 9/11 Memorial as part of the renovation to the Willowbrook Police Station. The memorial features the remains of an elevator floor platform and support framing system recovered from the World Trade Center Tower 1 wreckage. The 1,500-pound artifact consists of two individual pieces with the elevator floor isolated from the steel support framing system by rubber bushings.  RRJ collaborated with the Village of Willowbrook representatives and the project architect to design a support platform to orient the artifact for display. 

A dedication ceremony of the 9/11 Memorial was held at an open house of the newly renovated Willowbrook Police Station on September 16, 2017.
