title: Sky Tower (Auckland) text: awards. The Project Architect was Les Dykstra. Taking two years and nine months to construct, the tower was opened on 3 August 1997. The tower is constructed of high-performance reinforced concrete. Its diameter shaft (containing three lifts and an emergency stairwell) is supported on eight "legs" based on 16 foundation piles drilled over deep into the local sandstone. The main shaft was built using climbing formwork. The upper levels were constructed from composite materials, structural steel, precast concrete and reinforced concrete, and the observation decks clad in aluminium with blue/green reflective glass. A structural steel framework supports the upper mast title: Sky Las Vegas text: Nevada Development Partners purchased the vacant property from NewMark Merrill in March 2004, at a cost of $13.5 million. The company was made up of Aaron Yashouafar, the chief executive of the Los Angeles-based Milbank Real Estate Services Inc.; and David Pourbaba and Neil Kadisha, developers from southern California. In July 2004, plans were announced for Sky Las Vegas, a 40-story, 350-unit condominium tower. Construction was expected to commence in the first quarter of 2005, and was expected to cost $300 million. The project was being designed by Klai Juba Architects. An advertisement for Sky Las Vegas was published on title: Skyscraper text: to use even more than two levels on an elevator, although this has never been done. The main problem with double-deck elevators is that they cause everyone in the elevator to stop when only people on one level need to get off at a given floor. Buildings with sky lobbies include the World Trade Center, Petronas Twin Towers and Taipei 101. The 44th-floor sky lobby of the John Hancock Center also featured the first high-rise indoor swimming pool, which remains the highest in America. Skyscrapers are usually situated in city centers where the price of land is high. Constructing a title: Sky Las Vegas text: Sky Las Vegas Sky Las Vegas is a 45-story luxury high-rise condominium tower with 409 units, situated on a 3-acre site on the Las Vegas Strip in Winchester, Nevada. A two-story retail project had initially been planned for the site in 2001, although it ultimately did not materialize. Plans for Sky Las Vegas were announced in July 2004, with construction beginning the following year and its opening occurring in May 2007. In February 2001, NewMark Merrill – a developer of strip malls in southern California – announced plans to purchase a property on the Las Vegas Strip. The property, located title: Skyscraper design and construction text: the value lost to the expanding service core. Many tall buildings use elevators in a non-standard configuration to reduce their footprint. Buildings such as the former World Trade Center Towers and Chicago's John Hancock Center use sky lobbies, where express elevators take passengers to upper floors which serve as the base for local elevators. This allows architects and engineers to place elevator shafts on top of each other, saving space. Sky lobbies and express elevators take up a significant amount of space and add to the amount of time spent commuting between floors. Other buildings such as the Petronas Towers
