One World Trade Center “Cocoons” Crews for Safety
Tishman considers workers’ safety at One World Trade Center in NYC
Dubbed a “hotel” for workers on One World Trade Center, the cocoon surrounding the concrete and steel erection is just one of a substantial list of innovative solutions Tishman has come up with to keep up with a demanding schedule (2 floors every 2 weeks) while keeping a close eye on safety:
Tishman, which reports no deaths or major injuries to date, is obsessed with worker safety. To protect crews, expected to peak at 1,500 this year, Tishman devised another first for a steel frame in New York City: A two-story, lightweight-steel traveling system, called a “cocoon,” wraps the upper limits of the frame in heavy netting and drapes nets down 16 to 20 floors. The cocoon, lifted by a crane as the steel grows, contains work platforms that hang off the steel. Ironworkers no longer have to balance on beams.
