Inherent in the concept was a solution to the high-rise safety dilemma.  Of those who died in New York on September 11th about two-thirds died because they were trapped above destroyed egress stairways.  Never again would occupants be trapped when cores below them were destroyed.  Instead, they could move horizontally via predefined exit paths and magnetically-held doors until they access the rooftop Stairway and exit safely to the ground. 

Pedestrian flow always segregates office employees and Memorial visitors for deference and security reasons.

To deter a vehicular bomb attack  the base is elevated with concrete deflectors and with swing away atrium laminated glass. The first 9 stories are hardened with a 10’ thick curvilinear reinforced concrete wall to deflect a blast around the structure. 

24 sections with firewalls and paired columns localize structural failure (similar to bulkheads compartmentalizing flooding on a ship) protect against panic caused by fear of a building collapse.  Occupants can move horizontally to an unaffected section hopefully avoiding human pileups in egress stairwells.

8 independent building cores with egress stairs and elevators are evenly spaced along the 750’ spine of the building. Each core functions as a separate redundant building in terms of electrical power, backup generators, elevator controls and sprinkler risers.  This allows use by slower occupants to speed evacuation going down and firefighters could get avoid climbing all the stairs thus preserving their energy while getting to the fire faster.  The egress stairs would not have to be oversize (7 WTC) to accommodate firefighters and their equipment.

A symbolic effervescent thin blue space frame traces the top edge of the clear glass representing our shared thin atmosphere as seen from space.  This space frame supports a nocturnal automated window cleaning apparatus like the original WTC to minimize human risk.  (This and a separate unit to clean the 87’ wide tall window are garaged at the bottom behind a blue glass door.)
