For example, Moody's said, as recently as two weeks ago airport officials assured the rating agency that a temporary tug-and-cart system was a viable alternative to the automated bag system. But last week project engineer Ginger Evans and Denver public works manager Mike Musgrave admitted that the airport needed an automated system on its two largest concourses. "The strong management resolve that had been clearly evident during the early years of the project, and was an important factor supporting the rating, must clearly re-emerge with a sustained focused effort toward project completion," Moody's said. In a telephone interview yesterday, Moody's vice president Adam Whiteman made it clear that despite the problems with the baggage system, construction risk did not play a part in the downgrade. The airport is built and any construction risk was reflected in the prior rating, Whiteman said.
