The concrete of the core cannot rise until all of the horizontal connecting steel for that particular level is installed.

Zen, am I right?

Yep.

Thank you for the great explanation. I knew it seemed different than other buildings where the core always seemed to progress somewhat independently of the steel work. Is the process being used on this building going to slow down the construction as opposed to more standard construction?

Will the core have to be the same height as the upper columns before they put them up?

...last week, the Port decided to spend $20 million to redesign the site so that Silverstein’s towers no longer contain key public infrastructure. That will allow the Port to build its projects without relying on an agreement with Silverstein. The design changes will affect architect Santiago Calatrava’s PATH hub, the vehicle security center and the Freedom Tower.

I'm sure the changes would be minimal, but I'm still not sure what they are. Maybe Zensteeldude would have more info.

NYGUY is it me, or am i still not seeing exactly where fulton street is, but the columns do seem very close to the street.

I dont want them as in sent to me, just graphic pics, sort of like what 9/11 research has for the original WTC, i just want enough to know where the beams go in contrast to the site

I don't think the Port Authority would be too keen on people putting the blueprints on the internet, even if they aren't the heavy duty kind that show the thickness of every beam and what not.

They put in the last perimeter column today and put up a flag and a patriotic banner to celebrate.

Freedom Tower has Kan. system

The Associated Press
October 31, 2009

A central Kansas company is playing a small part in building the One World Trade Center in New York.

United Industries Inc. is helping with the building's cooling.

The Freedom Tower is to be built where the World Trade Center once stood. The competition date is set for 2013.

United Industries says it constructed 17 condenser water filtration systems that will go on the buildings 104th floor and in its mechanical mezzanine

Last month, the company shipped the last six of the filter systems, said David Nash, vice president of the company's Tower-Flo Division.

The tanks will each be able to filter 475 gallons of cooling water per minute.

"They'll be stored in a warehouse," Nash said. "They'll not be hauled into the job site until they are onto the 104th floor."

The cooling towers will cool by spraying finely misted water into a column of moving air to transfer heat from the air.

The water captures minute particles of dirt and debris, which must be removed for the cooling to remain efficient.

United Industries' Tower-Flo system does this by forcing the water through sand.

"In a large building like this there is a significant heat load," Nash said. "When you add all the people and computers and electronic gizmos, there's a lot of heat accumulating you want to get rid of."

United Industries was founded in 1954 and relocated from Wichita to Sterling in 1995, Nash said.

The plant currently employs 15 people, manufacturing filter systems for industrial and recreational water systems.

The Freedom Tower sale is the company's largest single order for Tower-Flo filters.

The previous largest order was a nine-vessel, 7,000 gallon-per-minute filter system exported to a power plant in Chai Hui, Taiwan, in 2003.

Nash said he hopes publicity and the company's reputation from the World Trade Center will result in more work.

"It certainly gives us an inside track if they build a second tower," Nash said.

Just a reminder folks, you don't have to give a running commentary on whether or not the cam is up or down. It changes almost daily. If there's a problem, contact the folks there, no one here has any control.
