Cost Estimation in the News

Find a news article, magazine, or other periodical that features a project that was extremely complex. This may be from any domain such as construction, information technology, aerospace, etc. Examples include the cost overrun associated with the Big Dig (http://www.boston.com/globe/metro/packages/bechtel/) or the Seven Wonders of the Modern World.
