The last remaining permanent building on the project site, the Boardwalk Casino's mid-rise hotel tower, was imploded May 9, 2006. After most of the design process was complete, construction began without an official groundbreaking ceremony in June 2006. Most renderings of the project were released in September 2006 and some delayed until February 2007. The first concrete was poured on June 26, 2006. Prior to this all of the work was site preparation, including utilities and other infrastructure. A number of construction discrepancies have been found in the project. Construction of various parts of the site were covered by the TV show "Build It Bigger" in the episode titled "CityCenter, Las Vegas".
