Four towers under construction. The shortest one is just under one thousand feet tall. A Transit Hub, which will link fourteen subways, and the roof opens hydraulically. A Vehicle Security Center, a Museum, a Performing Arts Center, a Memorial, another Tower later...
Gee, just sixteen acres?
Fun...
LOOKING NE AT THE WTC (THE FILLED WEST BATHTUB) FROM THE ROOF OF THE WORLD FINANCIAL CENTER, TOWER 1 TO LEFT, MEMORIAL IN CENTER AND RIGHT. WHAT YOU DON'T SEE IS THE FOUR STORY BASEMENT BENEATH. EAST BATHTUB BEHIND.
LOOKING WEST AT THE EAST BATHTUB FROM THE ROOF OF 22 CORTLANDT STREET
TOWER FOUR RISING AT THE LEFT, THEN PROCEEDING RIGHT, TOWER THREE, THE HUB AND TOWER TWO FOUNDATIONS.
TOWER ONE FROM THE ROOF OF THE FINANCIAL CENTER. THE EXTERNAL CLIMBING CRANE IS ON THE LEFT. 35 FLOORS - 70 TO GO.
Just curious, what method do you use to transfer control upward? Nadir Plummet? Resection from monuments on nearby buildings?
One other question, how do you account for building movement when transferring floor control upward?
Scott made a post on the old POB site "PODs Survey Control For Very Tall Towers". It was very interesting for me so I printed it to PDF for future reference. If you want to send me your email address I'll send the PDF to you.
Frank,
I would love to have a copy of that pdf. Can you send me one also?
Thanks
