The Tilt-Up Concrete Association (TCA) announced a new heaviest panel on the Top Ten list. The new title-holder is the 339,000-pound panel for the Ocean Center in Daytona Beach, Fla. The owner selected tilt-up for this project because the method enabled them to achieve their desired look more economically than precast.
“The heaviest panel was set to span the width of the glass wall south entrance of the building,” says Trentis Durden, president of Sunshine Specialities Inc., the tilt-up panel erection contractor. “As a convention center, it was important that this facility have open spaces and the use of this panel made that possible,” says Jim Baty, technical director for TCA.
Not surprisingly, the heavy panel posed several challenges during the lifting process. A critical lift plan was developed because of the zero tolerance for movement and very high risk assessment while the erection was in process. “We had to set two 200-ton crawler cranes in a two-lane road,” says Durden. “It was 529 feet long from the center of the south end of the building in either direction.”
An additional challenge was a tight jobsite that limited crane mobility. The challenging project was tackled by everyone working together as a team to develop innovative strategies. Ocean Center is scheduled to open Jan. 1, 2009.
