MGM Mirage builds the CityCenter in Las Vegas, Nevada. With a budget of $8.4 billion, a load of construction equipment and estimated completion date in 2009, the project will take 200 million gallons of concrete and a spot on the Las Vegas Strip. MGM Mirage has filled in the last 76 acres of available real estate on the center portion of the Las Vegas Strip with the largest privately funded construction project in the United States. CityCenter, a multi-use plaza with three hotels, a casino, luxury apartments, and retail and dining facilities, will cover about 18 million square feet and may cost as much as $8.4 billion. But MGM is not the only one footing the bill. Dubai World, the state-controlled investment fund, dished out $5 billion for the project and now holds a 50 percent stake in the megaresort.
