About one year away from Opening Day in Miami’s Little Havana district, the new Marlins Ballpark is reaching another milestone: the installation of the last major structural piece of steel to be installed on the retractable roof, which will happen at the Topping Out Ceremony this Friday, March 25.
During the ceremony, the steel beam will be signed by more than 800 construction workers as well as Marlins executives, Miami-Dade County officials, and City of Miami officials. After it’s installed, the remaining infill steel will be added prior to decking the center panel of the retractable roof. The last steel beam weighs approximately 6,845 pounds and will measure approximately 38 feet long. The retractable roof is composed of 11,000 pieces of steel held together by welds and more than 115,240 bolts. In all, the retractable roof weighs approximately 7,500 tons. The project remains on time and on budget, and continues to exceed all local employment participation goals.
This 1000-year-old topping out tradition started in Scandinavia when workers would place an evergreen tree on the highest structural element of construction as a symbol of the workers’ respect for nature’s contribution to the building process. This tradition continues as a sign of good faith and well wishes for the building and its inhabitants. The traditional topping out tree will be placed on the last piece of steel at the new Marlins Ballpark.
