Tutor Perini Corporation (NYSE: TPC), a leading civil and building construction company, today announced that it has recently been awarded a contract by the National Railroad Passenger Corporation (“Amtrak”) to construct an underground concrete casing (“box tunnel”) beneath the Eastern Rail Yard of the Hudson Yards site in New York City. The contract value is approximately $133 million and the project has been funded through a Federal Transit Administration Hurricane Sandy relief allocation. The project—a key element of Amtrak’s Gateway Program—is intended to preserve an underground right-of-way for possible future expansion of rail service via two new tunnels underneath the Hudson River between New Jersey and Penn Station, New York. The box tunnel will measure approximately 800 feet long, 50 feet wide, and 35 feet tall, and will extend underground from 10 th Avenue to 11 th Avenue between 31 st and 33 rd Streets. Construction is expected to begin in August 2013 and substantial completion is expected in late 2014. The contract value will be included as part of the Company’s reported second quarter backlog.
