Hillsdale self-performed fabrication and erection of over 18,500 tons of structural steel for the shade canopy roof structure on the Miami Dolphins’ Hard Rock Stadium
. The 626,000-square-foot, long-span, cable-supported canopy is designed to withstand Category 4 hurricane winds and is completely independent from the existing stadium structure. (8) concrete super-columns provide bearing points and working in conjunction with a structural cable system perform the support and stabilization of the roof structure. (4) steel masts rise in the corners between each pair of columns with the spire reaching an elevation of 357’. At each mast, (4) forestay and (2) stabilizing structural steel cables, 5” and 3” in diameter, attach to the roof structure from the masts’ cable hub section and (4) 5” diameter backstay cables connect from the hub to ground-level embeds.
Hillsdale Fabricators began preassembling truss sections in a portion of the stadium’s parking lot in July of 2015. During steel erection, multiple 4-crane picks were performed using (4) Manitowac 18000 cranes with the largest installed assemblies being 440’ in length and weighing 700 tons. Steel erection began in January 2016 with the topping out taking place on July 29, 2016.
