Photovoltaic Panel Installation for University of Chicago Medical Center

A large land-locked roof replacement with multiple levels. Staging with 7 story scaffolding in an area that also housed MRI equipment and other sensitive equipment and testing. Slope of the main roof surface was 4/12 with low parapet walls along the perimeter. Many vent intakes and exhaust vents on the different roof levels. Logistically challenging, the dock where we had to make the deliveries and remove the debris was very active, only one vehicle at a time, and special accommodations had to be made with the sensitive deliveries that were being delivered to the different labs that the dock serviced.

Scope of Work: Tear off multiple layers of roofing and install at temporary roof in cold adhesive. Install insulation (R-20) and wood nailer that acted as insulation stops due to the existing slope. Installed multi-ply modified bitumen roof system (in cold adhesive) that had a reflectivity of .83. After the roof was installed, we installed 59 photovoltaic panels. Worked started late fall 2011 and finished in spring of 2012.
