Four former employees of Aggregate Industries, N.E. (Aggregate), have been convicted of various counts of mail fraud and highway project fraud and, with the exception of one of the defendants, of conspiracy, for the supply of sub-standard or out-of-specification concrete to Boston’s federally financed Central Artery Tunnel Project (CA/T), reports Leagal Inc.
The multi-billion dollar CA/T project, commonly known as the Big Dig, is a 12km long highway that links Boston to the north and south interstate highways and Logan Airport. With some 50% placed underground, construction required concrete tunnel walls, base slabs, and roof slabs with specifications that mostly prohibited the water addition of after concrete batching. The specifications also required concrete installation within ninety minutes of batching, with contractors required to submit “batch reports” detailing concrete delivery. The contractors were all made aware that submission of false batch reports was punishable by criminal sanctions.
Sentencing is scheduled for the last week of May.
