The Metropolitan Transportation Authority (MTA) today announced that the $1.1 billion “Running Tunnels and Underground Structures” contract, the first portion of the $2.1 billion Line Extension Project will be awarded the 2013 Construction Project of the Year by the New York State Society of Professional Engineers. It was completed five months ahead of schedule and under budget.
The Subway Line Extension will provide transit access to the West Side of Manhattan, including the Jacob Javits Convention Center, by extending the Line westward from its current terminus at Times Square to a new station being constructed at 34th Street and Eleventh Avenue. It will help to stimulate economic growth and continuing development of the area. The Hudson Yards Development Corporation is overseeing the program.
The Line Project is to receive this award for outstanding professional engineering efforts in developing creative solutions and innovative technologies in construction of an infrastructure project. The project used the first double-shielded tunnel boring machines (TBMs) to tunnel under New York City while placing precast concrete segments to form the tunnels’ walls. For the first time in New York City, a ground freezing method was used to harden soil to act as rock which allowed the TBMs to maintain proper course while boring and placing the tunnel liners.
“This is a significant award for the Line Extension Project.” said Dr. Michael Horodniceanu, President of MTA Capital Construction. “It recognizes the aptitude of our contractors and construction management team in the face of complex challenges.” The Line is being built by a JV of Shea/Skanska/Schiavone, known as S3II.
The Line Extension is scheduled to open in June 2014.
