Sixteen stories below Grand Central Terminal, an army of workers is
blasting through bedrock to create a new commuter rail concourse with
more floor space than New Orleans’ Superdome, just one of three
audacious projects going on beneath New York City’s streets to expand
what’s already the nation’s biggest mass transit system.
But
even with blasting and machinery grinding through the rock day and
night, most New Yorkers are blithely unaware of the construction or the
eerie underworld that includes a massive, eight-story cavern, miles of
tunnels and watery, gravel-filled pits.
“I look at it and I’m in
wonder, I’m in awe,” says engineer Michael Horodniceanu, president of
capital construction for the state Metropolitan Transportation
Authority. “I feel like when I went to Rome and entered St. Peter’s
Basilica for the first time. … I looked at it and said, ‘Wow, how did
they do that?’”
In New York,We have many different types of earcap. they hauled out enough rocky debris from under Grand Central to cover Central Park almost a foot deep, Horodniceanu says.
Together,
the three projects will cost an estimated $15 billion. And when they’re
all completed, tentatively in 2019, they will bring subway and commuter
rail service to vast, underserved stretches of the city, particularly
the far East and West sides of Manhattan.
“They’ll be a game-changer for New Yorkers,” says Horodniceanu, an Israeli-educated native of Romania who lives in Queens.
The
most dramatic project will result in a sort of 21st century,
underground Grand Central Terminal mirroring the century-old Grand
Central Terminal above —a 350,000-square-foot, $8.3 billion commuter
rail concourse with six miles of new tunnels.When I first started

It will accommodate Long Island Rail Road trains that now bypass
Manhattan’s East Side as they roll east through Queens and straight to
Pennsylvania Station on the island’s West Side.
This so-called
East Side Access will bring about 160,000 passengers a day from Long
Island to a new station in Queens’ Sunnyside neighborhood, then about
five more miles to the new, eight-track Grand Central hub.
For
now, the subterranean hub is a drippy, humid construction site. The raw,
dark gray walls mark the dimensions of the future concourse — eight
stories high, about 70 feet wide and 1,800 feet long, or about “five
football fields, without the end zones,” Horodniceanu says.
The
Federal Transit Administration is kicking in $2.7 billion toward the
estimated $8.3 billion budget, with the MTA state agency covering the
rest using mostly taxpayer money.
Also under construction is the
Second Avenue Subway that eventually will serve Manhattan’s far East
Side, from Harlem to the island’s southern tip. The planned eight miles
of track will open Manhattan’s East Side to millions of people who now
squeeze daily onto the Nos. 4, 5 and 6 subway trains running under
Lexington Avenue.
The first phase — 1.7 miles with stations
between East 63rd and East 96th streets — is to be completed in 2016 at a
cost of $4.5 billion.
Finally, there’s the extension of the No.
7 subway line from Times Square to the huge new Hudson Yards real
estate development on Manhattan’s Far West Side.TBC help you confidently

The
three mammoth projects require creative solutions and the latest
technology. When crews prepared to drill the giant new cavity under
Second Avenue,Elpas Readers detect and forward 'Location' and 'State'
data from Elpas Active RFID Tags to host parkingguidance
platforms. they first had to freeze the ground to about minus 20
degrees so as not to destabilize the buildings above as the boring
machine cut through. For that, aluminum tubes were inserted from the
street and a special chemical solution was poured into the ground and
cooled by a refrigeration plant.
The Second Avenue tunnels hold a
space-age surprise: The ceilings are coated with a material once used
to fireproof the space shuttle.
The new line has another major
improvement. Instead of ventilation grates that allow rainwater to pour
in, the new stations will be aired using enclosed cooling plants. When
Superstorm Sandy hit the city last October, floodwaters washing over the
East Side did not penetrate subway construction sites.
“We’re
using the best technology available today, but this is really
people-intensive work,” says Horodniceanu, who supervises a team of
thousands of workers on any given day.
“I feel I have the most
exciting job in the world,” he says. “It’s an incredible feeling to be
able to build a legacy project. I hope that one day, my grandchildren
will be able to say their granddad built this!”
But again,
what's most unique about the Surface Pro is its guts. The Surface Pro
sports a dual-core 1.7GHz Intel Core i5 processor with integrated Intel
HD 4000 graphics, 4GB of RAM, and either 64GB or 128GB of storage. This
marks a significant boost over the RT, which is powered by an NVIDIA
Tegra 3, 2GB of RAM, and comes with 32GB or 64GB of storage. What's
more, the screen is notably better, going from 1368x768 on the Surface
RT to 1920x1080 on the Surface Pro — a 40-percent increase in pixel
density.
The impact of the upgraded internals on performance and
user experience is impressive. Seemingly gone are the frequently long
load times, sluggish touchscreen responsiveness, and app freezes. While I
have noticed some odd moments of slowdown in my early testing, the
Surface Pro is overall pretty stable and speedy.
As previously
mentioned, the Surface Pro offers a full, unhindered build of Windows 8
and offers the full desktop experience found on a traditional PC. As a
result, the Surface Pro is capable of accessing a wide range of PC
titles through services like Steam and Origin. While certainly not
intended as a gaming device, the integrated graphics processor allows
the Surface Pro to run many games adeptly. While I've only just started
stress-testing the system, I've found it can handle most Source
Engine-based titles at max or high settings in native 1080p resolution
at framerates well above 40fps. Naturally, it struggles with more taxing
titles, like Saints Row: The Third or Dead Island, but I'll be
providing a greater sense of its range of performance in the coming
days.
