EAST SIDE ACCESS TUNNEL The Metropolitan Transportation Authority’s East Side Access project will connect the Long Island Rail Road’s (LIRR) Main and Port Washington Lines in Queens into a new LIRR terminal beneath Grand Central Terminal in Manhattan. The new connection will increase the LIRR’s capacity into Manhattan and significantly reduce commute times for tens of thousands of daily passengers. In 2006, a joint venture of Judlau Contracting, Inc. and Dragados USA was awarded a $427 million contract for the Manhattan Tunnels Excavation. Judlau has bored four tunnels of approximately 25,000 linear feet utilizing two tunnel boring machines with a capacity to bore 22-foot diameter tunnels. We are mining approximately 120 feet beneath Manhattan streets under the many utilities and existing tunnels such as IRT # 7 Line, Lexington Avenue Express 59th Street Station, 60th Street BMT Lexington Avenue Station, the existing 63rd Street Station and active Con Edison steam and power lines. Additional work includes approximately 30,000 yards of cavern (Wye) excavation as well as cross passages and sumps, performed conventionally with drill and blast. Following the excavation, the tunnels and caverns will be lined with both shot-crete and cast-in-place concrete. In 2008 a joint venture of Judlau and Dragados USA
commenced work on a $ 734 million contract for the
excavation of two caverns that will eventually function as the new Our contract also includes the excavation and lining of both cross
passages and CIL. We will also be performing the jacking of
the existing Grand Central Terminal for the removal of existing
columns and the construction/ erection of columns and fractured
