Category 3 Winner – Steel -- InteliBuild, a division of Canam Group
New Marlins Ballpark - Retractable roof
Widest stadium retractable roof -- Composed of over 7,000 tons of high-strength steel, the span of each retractable roof panel from rail to rail is approximately 530 feet at each lower panel and 566 feet at the upper panel. The opening created by the long span of the 45 foot deep upper panel truss is wider than any NFL retractable roof stadium. The south track beam structure is lower than the north track beam to minimize the overall building height and allow for roof panel movement due to the affects of sun and wind.
Advance coordination results in smooth field testing -- Because of advance coordination through simulations of the sliding roofs, the first testing in the field went smoothly without any interference between the 3 roof panels. The most complicated element of the project was the wishbone plate assemblies located on the north end of each of the 12 trusses. They were composed of over 50 plates and weighed around 16 tons each.
