Could it have something to do with the cable snapping on the smaller TG model on T4 for both questions? Hopefully the preexisting custom climbing platform on the TG-2300 can be adapted to a new crane. Off-Topic, Is this why the TG crane intended for 1WTC's spire in the rigging diagram was replaced by a Favco?

Sucks about the cranes. Won't that be a significant expense to take them down, particularly if they're planning to erect them again shortly thereafter?
very. apparently that is a major cost problem.

Yes. There are a lot of built up columns that still need to go in. They will have to use 760's. 1280's are too big.

yes it did. There were actually two drops on the site with the TG cranes, but one was not carrying a load, the cable just unspooled on its own.

The history here is that FMC used to own Link Belt and produce these cranes. Cornell bought the TG patents from FMC when they sold link belt and are THE company that handles TG cranes nowadays.

The problem stems from the fact that Cornell is not technically the manufacturer of these cranes and the DOB said they cannot verify that there is still a manufacturer of the cranes since FMC is no long in the business. It also has the DOB spooked because technically the original design for this crane dates back to the 70's. This is all kind of nonsense because as I understand it Cornell does produce new parts for the cranes that they do own. And I know for a fact that the Cornell TG cranes are kept in top notch condition. The TG cranes are used all over the country and were designed initially for the nuclear power work that was going on at the time. Heavy lift tower cranes.

So with regards to the two 'drops'. It is still a point of contention, but the DOB would argue that an inherent design flaw in the crane allowed the closed hydraulic loop to get contaminated with water, thus causing the braking systems to not work.

The DOB has no jurisdiction on PA property, there is a great history of that. the PA will actually not even let a DOB inspector on the site unless a request is given, and the DOB will not go on PA property without a request from the PA. Very touchy.

NORMALLY, the PA asks contractors to fill out the paperwork that is normally required by the DOB for a Crane Notice, and to submit that paper to them, not to the City.

However, apparently with this situation, and the wave of crane incidents over the past years, the PA is NOT fighting the CITY on this and will require contractors to comply with the DOB directive.

That climbing frame on tower 3 is totally custom for the building. It was designed specifically for the 2300 and its tower sections. They are not cross compatible with a 760. As I hear, there will be a considerable amount of engineering required to make a favco tower work on top of that TG tower section. An adapter if you will.

I do not know what the plan is to get Favco's on the building.

Consider that when an erector plans a job, the sequencing of steel, the maximum sized picks on the job, the radius of work, etc. Everything is coordinated with the crane size in mind. I would have to imagine this messes up the plan a good bit.

overall clusterf--- for the erection plan.
Where did you hear the information about the release to continue fabrication? Also wasn't a significant amount of the steel already fabricated? If that's the case then maybe erection will start with the steel is already fabricated well before February.

Sounds like the DOB is showing their muscle again! Unless they can prove a design flaw with the design of the TG cranes I wouldn't be surprised if they got a lot of pushback on this issue. Does anybody know how many TG cranes are operating in the city other than the ones on the site?

you can assume i am telling you second hand.

they need six months to fabricate a backlog of stored material

i dont believe there are currently any operating TG 1900 or 2300 cranes in new york city, (assuming you exclude the one set up on tower 3)

the DOB is not approving any new Crane Notices for TG cranes.

Too much staging for the tower's outer structure, fascinating to know just a bunch people will actually know those big columns are fake!

The outer metallic wrapping has no function other than to emphasize on one of the elements of the tower's architectural language. The real columns acting along with the overall structure are much thinner and will be completely hidden.

Other than the cladding, nothing significant will happen.

BREAKING NEWS!!!!!!!!!!!!!!!!!!!!!!!!

IT'S PARTY TIME FELLAS!!!

GroupM signs huge 20-year lease at 3 WTC
http://www.nypost.com/p/news/busines...GKlCuUUL1x9kVI

Quote:
In a major step forward for Downtown, media giant GroupM and developer Larry Silverstein today agreed on major terms of a huge lease at 3 World Trade Center, The Post has learned.

The deal is likely to be completed by fall. It will allow the tower, now on hold at seven stories, to soar skyward to its full 80-story height starting next year and open in late 2016.

Real-estate and advertising industry sources said GroupM, the media buying and planning arm of WPP Group, will take 515,000 square feet for 20 years in the tower designed by “starchitect” Richard Rogers.

The 2.5 million square-foot project, officially named 175 Greenwich St., will rise between Silverstein’s 4 WTC and the Santiago Calatrava-designed PATH terminal. A retail base is nearly completed, but Silverstein cannot build higher without first signing a major office tenant.

Today’s signed agreement, known as a term sheet, is not the same as a done deal. But term sheets lead to leases about 95 percent of the time. The completed lease will trigger $1.3 billion in Liberty Bond financing that will enable Silverstein to start full construction.

GroupM plans to take 9 floors in 3 WTC’s lower office portion, including five floors of 70,000 square feet each, sources said. The firm hopes to move more than 3,000 employees from several Midtown locations to 3 WTC in 2017.

Financial terms could not immediately be determined. Representatives for Silverstein and for GroupM did not return calls.

The Silverstein-GroupM talks were first buzzed about last year but could have fallen apart at any time.

The seven-story “podium” was needed to house a 183,000 square-foot shopping complex and to provide infrastructure for the rest of the WTC site.

The GroupM breakthrough helps the WTC regain leasing momentum it recently appeared to have lost to Hudson Yards, where Related Cos. is building a new headquarters for Coach Inc. and has a term sheet to do the same for Time Warner.

Two of four planned office towers at the WTC are already nearing completion. A finished 3 WTC will leave only 2 WTC, designed by Sir Norman Foster, yet to be built at the 16-acre site.

Condé Nast is the anchor tenant for the Port Authority and the Durst Organization’s 1 WTC.

WPP’s GroupM describes itself as the world’s biggest media investment firm with $90.8 billion in billings last year and 400 offices in 81 countries. It is the parent of media agencies including Maxus, MEC, MediaCom, Mindshare and Kinetic
