| Title | BP Bridge, structural steel, November 12, 2003 |
| Description | Work continues on the eastern approach ramp of the BP Bridge as the subframing for the stainless steel shingles transforms the structure to look like a rollercoaster! As was the case for constructing the Jay Pritzker Pavilion, Catia software, a three-dimensional computer-aided design software originally developed to design fighter jets, was used for the construction of the BP Bridge because traditional, two-dimensional drawings were not sufficient. |
