    Great pics CCR. I especially love the close-up of the worker standing under the back of the crane, it really gives an idea of just how huge that beast is.

    BTW what are those huge white beams for?

    That big thing looks like a box girder piece lying upside down.

    Are those white beams forming the bottom chord of the arched truss?

    All those big white beams look like more temprary supports.

    The bottom chord of the truss is a bit larger than the white beams.

    The blue one. The red one is a W36x650.

    Same model, different angle. It's the right length too.

    I think I may have said this before, but, the steel for the Transit Hub is far more interesting than that of any of the towers.

    That Manitowoc 18000 with the Max-ER kit isn't sitting there for nothing. There is some very interesting work for it ahead.

    (Without knowing the full details of it's current configuration I'm guessing it's rigged for at least a 250 ton lift at minimum radius. I have seen an 18000 with the kit do a lift where the kit was 2 feet off the ground. That's over 450,000 pounds of counterweight lifted off the ground !)

    here are the white beams, not the best pics. They were rolled under the #1 box

    Great shots 325 !

    All those big white beams are just temporary supports.

    (if those are just the temprary supports, imagine what they are there to hold up untell finished.)

    (Notice that the 18000 only needs it's secondary hoist to lift those beams.)

    Thanks!

    he needs the main hook for this!? lol

    LOL, I think he is just using the main hoist on the tent cause he is about to use it on the super column. Why run the secondary all the way down and then back up when he needs the main for the real lift.

    (I bet the lifting cables weigh more than the tent.)

    Trade Center Transit Hub’s Cost Now Over $3.4 Billion

    NY TIMES
    By MICHAEL M. GRYNBAUM
    February 24, 2011

    Four years ago, the Port Authority of New York and New Jersey said a $3.4 billion price tag for its new transportation hub at the World Trade Center site would be “simply unacceptable.”

    On Thursday, the authority accepted it.

    The birdlike glass-and-steel transit center, designed by the Spanish architect Santiago Calatrava and intended as a connection point for PATH and subway trains, is now expected to cost $3.44 billion, allowing for the steeply increased cost of the steel framework, Port Authority officials said.

    The higher price, which will require the authority to dip into a contingency fund for the project for the first time, represents a 5.5 percent increase from the agency’s last estimate of $3.26 billion, issued in 2008.

    Chris Ward, the current executive director of the Port Authority, said in a statement that his agency maintained the fund “for these types of circumstances.” He said the fact that nearly all of the contracts had been awarded made this “the right time” to use the additional funds.

    The budget for the transit hub has ballooned since 2003, when an initial proposal estimated the cost at $2.2 billion.

    That estimate was thrown out in 2007, when the general contractor for the project, Phoenix Constructors, announced that the cost could grow to $3.4 billion, a figure described as “simply unacceptable” in a memorandum by the authority’s executive director at the time.

    In the interim, the authority has pared some of the more extravagant details of the design, eliminating a retractable roof and several special support columns. Phoenix, the contractor, has since been disbanded.

    But the glass ceiling of the complex, intended as an iconic and elegant composition, has remained the prime source of cost overruns. The increase announced on Thursday stemmed, in part, from higher-than-expected shipping costs on the elliptical, stylish steel arches planned for the ceiling. The arches are being fabricated in Spain.

    The transit hub, which is expected to open in 2014, will be the third-largest transportation center in the city, behind Grand Central Terminal and Pennsylvania Station. About 250,000 people are expected to pass through its main concourse each day, and the retail space is supposed to measure 500,000 square feet, surpassing the size of the Time Warner Center.

    $180M Overrun at World Trade Center PATH Hub 'Not Bad,' Mayor Says Updated 5 hrs ago


    February 25, 2011 11:42am

    Mayor Michael Bloomberg described the ballooning price tag as "not bad forecasting."

    MANHATTAN — Mayor Michael Bloomberg downplayed the new World Trade Center PATH Hub's ballooning budget Friday, describing the $180 million cost overrun as "not bad forecasting."

    The Port Authority board announced Thursday that the cost of Santiago Calatrava's dramatic winged PATH hub at the World Trade Center had swelled to $3.44 billion — $180 million more than expected.
    Port Authority Board members expressed concerns about the hike before voting it its favor. But Bloomberg downplayed the new price as off by just 2 percent.

    "In all fairness, that's not bad forecasting," Bloomberg told WOR's John Gambling during his weekly radio sit-down. "These things aren’t specific," he said.

    Bloomberg said that cost overruns could be prevented "just by vastly overestimating the cost," but said that underestimating is better than over-reaching
    "You're better off underestimating, forcing people to watch the pennies. The trouble is, then, when you have to raise it, because of costs or things beyond your control," he said, adding that, often, over the course of building big projects, new ideas emerge and are added along the way, adding to the cost.

    The Port Authority, however, blamed the increase partially on security concerns that forced them to "harden" the PATH and subway station. As a result, a steel contract that was expected to cost less than $100 million came in at $205 million, Steve Plate, the director of World Trade Center construction for the agency, said.

    He also blamed high international shipping costs and overruns on smaller plumbing, electrical and mechanical contracts.

    The Port Authority will use money from a contingency fund to cover the extra costs.

    Bloomberg's preliminary budget for the coming year, released last week, proposes a 10 percent cut in capital spending to help close a multi-billion-dollar deficit.
