The recession has taken a major toll on the U.S. commercial real estate industry and the damage, in terms of construction costs, can be seen in black and white in Turner Construction Co.'s Third Quarter 2009 Turner Building Cost Index. Construction costs have plummeted by 10.77 percent since the start of 2009, a decrease not seen since 1930, when costs dropped 10.8 percent in the months following the stock market crash of 1929.
