King Shaka International Airport Entrance

2011 TCA Tilt-Up Achievement Award - Special Projects Division

Article tools: Coming soon!

This project was characterized by the extremely short duration of six weeks and a limited installation window between 8:30 p.m. and 5:00 a.m. for two nights only, as the panels were erected on the roads in and out of King Shaka's Durban Airport.

There was no feasible in-situ concrete solution to this project. Twenty panels in total were required. Therefore, two phases were created to cast and install ten panels during each phase. The casting surface and show face of the panels were created using concrete Tilt-Up formwork. The panels were flat lifted by two cranes, placed onto specialized Tilt-Up concrete cradles cast at the same radii as the underside of the curved panel, onto trailers.

The panels are curved in two planes, have a moment connection into the base foundation and are cantilevered 11.5m. The Tilt-Up technique was cost-effective, offered savings in program duration and a quality unachievable with conventional building techniques.

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.
