Beginning in 1999, I began to document the construction of Millennium Park on a vacant railroad yard in the heart of downtown Chicago.  Over the next seven years, I had unrestricted access to the site and made several visits to Performance Structures in Oakland where the “Cloud Gate” sculpture (aka “the Bean”) was fabricated. Construction has been a passionate interest since I went down in the Deep Tunnel on a photo assignment in 1980. Since then I have photographed the construction of the Miro sculpture in downtown Chicago, the building of the Physics Center, and the renovation of Rockefeller Chapel at the University of Chicago. What makes Millennium Park so interesting is the scale and variety of work going on any given day.  The challenge is to capture the smallest tasks and fit them into the large changes taking place at the foot of the Chicago skyline.
