Update on the Big Stuck

The latest on the Bertha, the Seattle tunnel boring machine in the Seattle Times.  The current issue of Bloomberg Businessweek has an excellent history and profile on the $80 million tunneling machine broken under Seattle - Stuck in Seattle.  From the article:

"Brent Flyvberg, a professor at Oxford's Said School of Business, has followed Bertha from afar.  His research on mega-projects had been cited by both backers and critics of the tunnel.  Nine times out of 10, massive infrastructure jobs go over budget, he says.  Tunnels on average cost 34 percent more than anticipated .  No region is better at predicting costs, and estimates over the past century haven't become more accurate, his data shows."
