How Did They do That –Install the Schuman Pavilion Pedestrian Bridge That Connects the New with the Old Making a Dramatic Change to the Main Entrance
For me, there is nothing like being on the construction site under the lights where the construction sounds punctuate the stillness of the night as the shadows accentuate the size of man and machine. In the early morning on September 22, 2019, just before the clock struck two, the first in a convoy of six flatbed trucks carrying crane parts, and counterweights rolled into the north yard off of Prospect Avenue. Not far behind was the Liebherr seven-axle LTM 1400-7.1 mobile crane having a maximum load capacity of 400-tons.

While the crane is being staged another very important piece of the project is going on at the top of the north pedestal. The welders are prepping the steel on top of the cap. This step must be completed before the bridge is set on the pedestals.

The First Pick (Move)
Because of a tight slew radius between the crane and bridge’s resting position a two-step process was required. The first pick (move) required that the bridge be moved west to a predetermined point toward the pilings onto which the bridge would set. After the first pick (move), the crane would be set on the wooden risers while the cable is released, and the crane moved to a more radius friendly location nearer the pilings. Tearing down part of the crane and moving it required some time.
