It is was one of the most impressive construction jobs of
2002, and it meant a great deal, not only to the 70,000 commuters
who ride the IRT subway everyday, but to our city and our
nation.
The most serious damage to the region's infrastructure caused
by the terrorist attacks of September 11, 2001 was the destruction
of the Cortlandt Street Station of the IRT subway line under
the World Trade Center. It had been (and is again) a major
stop on the 1 & 9 line, the local subway route that serves
Manhattan's west side and the Bronx.
Even before the WTC site was completely cleared, the Metropolitan
Transportation Authority awarded a contract to rebuild the
collapsed subway tunnel from Barclay Street through to Liberty
Street to a joint venture of Tully Construction Co. Inc. and
A.J. Pegno Construction Inc. The work, which cost $92 million,
began in February and completed by September 2002.
To start with, MTA engineers developed an in-house design
using original 1915 blueprints of the station as the basis
for the work. Next came the clearance and demolition of the
ruins. Beams from the 80th floor of the Twin Towers had pierced
the street and subway box, coming to rest on the subway roadbed
below. As a result of water main breaks, 26 million gallons
of water had to be pumped out of the tunnel.
"If you saw the destruction inside that tunnel and the
damage to Cortlandt Street, you would never have imagined
that one year after our city was attacked, that the tunnel
would be rebuilt and we'd be running again. But we are,"
said MTA Chairman Peter Kailkow.
Once the rubble was removed, a rat slab, a coating of concrete
on the bottom of the tunnel to provide smooth grade, was poured,
followed by waterproofing.
Concrete boxes supplied by Conesco Industries Ltd. of Little
Ferry, N.J. were used as forms for the pouring of the new
tunnel structure and the footings for the steel posts. The
steel was provided by Michaelman-Cancelliere of Bath, Pa and
erected by Budco of the Bronx. After that, tracks were lain,
power, lighting, communications, pumps and ventilation installed
and tested.
The new Cortland Street Station is a simple box-like structure,
measuring 800-ft. by 70-ft. It took 45 miles of new cable,
6,200 cu.-yds. of concrete and 1,050 tons of steel to complete.
Getting such an enormous job done so quickly and efficiently
meant a 24/7 schedule using 150 to 200 workers per shift.
"I want to congratulate all the men and women who worked
tirelessly to complete these important projects in record
time," New York Governor George Pataki said at the reopening
ceremony on September 16th. "A reconstruction effort
thought to take years was accomplished in months."
The reconstruction not only allowed the 1 & 9 to ride
to the end of the line at South Ferry, it also meant that
the Nos. 2 & 3 trains were able to return to express service
connecting the Bronx, Manhattan and Brooklyn.
