Federal and Massachusetts prosecutors are investigating allegations that Aggregate Industries, the largest supplier of concrete to the Big Dig, delivered substandard concrete to the $14.6 billion project. Investigators have turned up evidence that the company had drawn up phony documents to make it appear that truckloads of old or rejected concrete were freshly poured.
The state attorney general is working with the FBI and the Boston US Attorney’s Office to prosecute the case.
The Boston Globe ran an August 11, 2005 story on developments.
