The MGM CityCenter, a "city within a city," was developed through a joint venture between MGM Mirage and Dubai World. the $8.5 billion mixed-use property consists of seven major buildings encompassing 17 million square feet of hotel rooms, high-end residences, casino/gaming areas, convention spaces, meeting rooms, and an exclusive retail, fine dining, and entertainment district.
A $65 million state-of-the-art, 2,100 foot long automated people mover (APM) system was constructed to connect the CityCenter complex to adjoining MGM properties. The steel truss superstructure is supported on 24 piers; hammerhead cross beams that are supported on single column bents. The piers are also supported on pile caps sustained by deep foundation, drilled shafts. The predetermined pier locations and span arrangements were based upon the architectural, functional, and circulation requirements of the CityCenter property.
WSP provided independent analysis and verification of the steel truss superstructure and final design of the concrete columns and foundations for the dual-lane structure elevated from 50 to 80 feet above the ground. The project also included development of the APM structural design criteria, peer review of the station structural design, design of the freestanding automatic doors at the stations, and design of the maintenance area steel platforms.
An aggressive project schedule was designed to accommodate the construction of other CityCenter components. WSP was actively involved during the entire construction administration phase of the APM system. Close coordination and open lines of communication between WSP, the contractor, and the owner contributed to successful project completion within budget and on schedule.
