A tower crane lowers a concrete slab as the demolition continues of the unfinished Harmon Hotel tower on Monday, Sept. 22, 2014, in Las Vegas. The planned 47-story tower, part of MGM Resort International’s $8.5 billion, 67-acre CityCenter development, was deemed structurally unsound after defects were found in 2008 during construction. The tower will take about a year and $11.5 million to deconstruct. (Photo by David Becker/Las Vegas Review-Journal)
