MTA has awarded two new contracts worth $628 million to fit out over 3 kilometres of new subway tunnels beneath New York city.
As well as lining tunnels between 50th Street and Park Avenue to 63rd Street and Second AvenueTutor Perini, the contracts cover the installation of the communications system at a new Long Island Railroad concourse beneath Grand Central Terminal.
Frontier-Kemple will carry out the structural concrete lining of the tunnels to the north of the new terminal while Tutor Perini install the communications system which will support radio and public address systems at the new underground station.
The contracts will fulfill another element of the $8 billion East Side Access project.
“Tunnels that have been drilled through Manhattan bedrock will be waterproofed and lined with concrete and readied for tracks. A cavern that is presently a raw concrete space will be activated with advanced communications networks that will be used by tens of thousands of people each day,” said Michael Horodniceanu, president of MTA Capital Construction.
“When Long Island Rail Road riders come to Grand Central, the systems that will be put in place through these contracts will serve as an unseen backbone making train service possible.”
