Comprised of four 30ft by 63ft custom-built screens suspended from a halo-shaped truss and cage with an additional circular LED display screen underneath, the video display makes use of 54 million LED lights.
According to Rentenbach project executive Tony Pettit, “I’ve been in this business for 40 years, and this is the most unusual project I’ve ever seen. Plus, every component of this project was big—from pins to bolts to towers.”
In January 2016, Barnhart began erecting four permanent 200ft-high towers, one at each corner of the stadium. Next, the team had to unroll, suspend and raise the 3.5in-diameter cables that measured between 576ft and 676ft in length, with a weight of 27lb per foot, without damaging the stadium’s bleachers or sky boxes.
Utilising a system of winches, crane bocks and temporary cables, Barnhart was able to lift the permanent cables and connect one end of each to a tower, then pull cables from the opposite towers.
Barnhart assembled the halo and cage. Once the cables were in place, it employed two Manitowoc 999 cranes to lift the 130,000lb halo in March.
Barnhart personnel, working from man baskets lifted by smaller hydraulic cranes, connected the 3.5in suspension cables to the halo pin connections. The cranes were then used to lower the halo until it was fully supported by the suspension cables.
Two weeks later, Barnhart used the Manitowoc cranes aided by two 350t hydraulic cranes to lift the 160,000lb cage into place. The project was completed safely and in time for its planned unveiling in mid-April 2016.
