There's been a third death at MGM Mirage's Project CityCenter in Las Vegas.

On Aug. 9, an elevator counterweight system struck and severed the body of Harvey Englander, 65, who had leaned over into the shaft to grease the elevator lift on a 60-story hotel tower, says a spokesman for the Clark County Fire Dept.

In February, a pair of 3,000-lb. walls fell at the construction site and killed two workers.

CityCenter is the nation's largest privately-financed project, with 3,600 tradesmen present at any given time. The 76-acre, seven-building development will eventually see up to 7,000 trades workers and 350 supervisory personnel during the peak of construction activity.
