Inside the steel frame of One WTC are one-meter-thick concrete walls encasing the elevators and stairwells as well as communication and safety systems. In total, the building is expected to require 150,000 cubic meters of concrete. “What we’re doing with this concrete core is so different,” Tollner says. “It’s almost like we’re building a nuclear power plant or something. It’s not like building a regular office building.” (source)
Occupants of the towers—those that work there daily—will receive CLEAR card-like trusted security badges that will allow them to bypass the normal screening lines. As the worker passes through the security turnstile, a proximity chip in the ID card activates the Destination Dispatch System that controls elevator service. “So, if you work on the 38th floor, it will automatically tell you which elevator to go to that will take you directly to the 38th floor.” del Valle said, “It’s a security feature so that people who are in the building for a specific purpose get there only.” (source)
Watching over this process will be an undisclosed number of the 670 NYPD officers who make up the Lower Manhattan force—more than in any other district in the city and more than the entire city of Oakland, CA. More than 400 closed-circuit surveillance cameras positioned in and around the complex will provide live feeds to a 24-hour monitoring command center located nearby. The feeds will also be monitored by video analytic software that is designed to recognize suspicious people, activity and unattended baggage. (source)
