The Florida Marlins announced the first vertical concrete pour for the ‘super columns’ of the new ballpark structure took place Friday, September 11 at 1 P.M.

The pour constituted the first 16 feet of the 40-foot tall rebar cage that was erected the previous week. When complete, the elliptical shaped column will stand approximately 8 feet wide by 15 feet long and will rise to 130 feet.  The column is one of the twelve super columns that will support the 8,300 ton Retractable Roof Structure, which is approximately the weight of the Eiffel Tower in France.

“This important milestone continues to signal the progress of the ballpark and we are pleased that an increasing number of workers are contributing to the continued success of this project,” said David Samson, President of the Florida Marlins.

About the Super Columns and Retractable Roof

The construction of each of the 12 super columns will be divided into six phases. A phase is composed of preassembling the rebar cage horizontally on the ground, hoisting the rebar cage vertically into position, placing utility conduits, placing the formwork that shapes and contain the concrete, placing the concrete, and then removing the formwork after the concrete has reached its curing time. The process is repeated until the columns have reached the final elevation.

The retractable roof consists of three panels elevated over the playing field supported by a two track system on the North and South Side of the Ballpark. The first column that will be poured this Friday is part of the North Track system which will be approximately 30 feet taller than the south columns when complete.


The new ballpark’s footprint will have a South East orientation, with unobstructed views of Miami’s skyline made possible by six operable glass panels.  The ballpark will be located on the parcel of land bordered by NW 6th Street to the north, NW 4th Street to the south, NW 16th Avenue to the west and NW 14th Avenue to the east. With a capacity of approximately 37,000 spectators, the retractable roof, air-conditioned ballpark will contain 928,000 square feet on the former Orange Bowl site. The ballpark will celebrate Opening Day in April 2012 and will attract a wide variety of events throughout the entire calendar year.
