WPLG-TV

2010 TCA Tilt-Up Achievement Award - Office Division

Article tools: Coming soon!

Home to state-of-the-art digital broadcasting, WPLG-TV is the first station in the Southeast U.S. with high-definition digital technology in both the studio and the field. Their new facility reflects a linear element with strong vertical intersecting planes.

Tilt-Up was selected for this project because of the complex design vision of the architect. By using Tilt-Up, the team was able to meet the design requirements within the budget, using the specified materials. Given the area’s propensity for windstorms and hurricanes, it was critical that the news station remain operational during those events. Tilt-Up assured strong structural durability while still enabling schedule and cost restraints to be met. During construction, because of site constraints and lack of access to three sides of the building, 80 percent of the Tilt-Up panels needed to be constructed outside the building limits. This was done using three erection sequences, not including the satellite tower, to complete the 122 Tilt-Up panels on the small building footprint.

Additionally, there were a large amount of recessed floor areas that were needed to accommodate numerous computer lines beneath the finished floor. A super flat slab for the studio and multiple lowered slabs for computer flooring were utilized. This was critical for the project to ensure that all the sophisticated high-definition broadcasting equipment could perform properly. Tilt-Up was also used for the 99-foot, 6-inch tall satellite tower, which represents a unique application of the Tilt-Up method.

This was the most challenging erection sequence because the area available for the crane left no room to spare. It barely allowed for the size of crane needed to handle the weight and reach of these tower panels, while at the same time allowing enough access to set and weld the pieces. The tower erection also required extensive coordination between the ornamental steel and the Tilt-Up, as they were interconnected beneath the cantilevered sections of the upper tower.

Winner of a number of awards (including one for Craftsmanship in Tilt-Up panel fabrication and one for crane operations), the marriage of architectural vision and durability provided the owner with a unique facility and added visual appeal.

About the TCA

Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
