Any structure rising more than 500 feet demands a sound foundation. When the structure moves-and holds more than 1,100 people-there is no room for error.
Members of the Reinforcing Ironworkers Local 416 had to complete their work before other ironworkers could erect the Las Vegas High Roller-the largest observation wheel in the world. The High Roller, slated to open in March, anchors The LINQ, a $550 million open-air retail, dining and entertainment district developed by Caesars Entertainment.
The foundation of the High Roller was just one part the LINQ project, says Curtis Van Norman of CMC Rebar in Las Vegas. The entire project used approximately 1,300 tons of rebar and required 17,000 labor hours to install.
The High Roller brace legs are mounted on plinths that were especially challenging. The plinths extended out of the ground and cantilevered above grade. The plinths are conical on two sides and beveled on the other sides.
“No two bars could be fabricated the same and required a 3D rendering to aid in fabrication and placement,” says Van Norman.
