Miami Marlins Ballpark: Miami Marlins Construction Facts

The new Miami Marlins ballpark was built over the historic Orange Bowl site in Little Havana in Miami. The Miami Marlins ballpark features an amazing retractable roof, with 37,000 seats and natural grass playing field. This amazing stadium is also being considered as the first LEED Silver Certified retractable roof Ballpark in Baseball. The construction team was led by Populous, the architect; Hunt/Moss, a joint venture, the general contractor; Walter P Moore, the structural engineer for the roof; and Bliss & Nyitray, the structural engineer for the stadium bowl for the new facility. This is the sixth retractable roof designed, built, and commissioned by the Uni-Systems/Walter P Moore team.

Miami Marlins Ballpark: Retractable Roof

The Miami Marlins ballpark retractable roof is composed of nearly 8,000 tons of high strength steel. The roof has been designed to move a combined 19 million pounds within 15 minutes, traveling at a speed of 39 feet per minute. Each span of the Miami Marlins ballpark is approximately 530 feet at each lower panel and 566 at the upper panel. The opening created by these movable panels is wider than any NFL retractable roof stadium. The retractable roof contains 44 transporters capable of supporting more than 1 million pounds of load. The mechanization of the Miami Marlins Ballpark has 76 motors each of them with 10 horsepower.

The retractable roof panels are controlled by a single operator allowing the roof panels to open or close each panel simultaneously, or if desired one panel at a time, providing partial shades to the Miami Marlins ballpark playing field.

Miami Marlins Ballpark: How It Was Built

The retractable steel roof of the Miami Marlins was assembled using state of the art technology using shoring removal technique. The roof although designed for horizontal travel, required to be installed by lowering and rolling the roof panels down the supporting ramps as the transporters moved at the same pace. The shoring system and the associated steel erection procedure for the roof structure were also meticulously designed to resist hurricane level winds. The structural roof elements were fabricated by Canam Steel and hoisted into place by LPR Construction.

The roof installation was so carefully planned that it enabled the false work to be used for additional long span structural construction, reducing waste from the inefficiency of discarded false work. The system employed at the new Miami Marlins Ballpark is the most efficient shoring system employed to date.
