A five-storey “cocoon” has begun climbing up a new Manhattan skyscraper. The protective shell moves under its own power like a living thing, but it’s actually a groundbreaking technology that has the potential to make skyscraper construction faster, safer and (as the name suggests), just a little bit cosier.
Metropolitan Walters, the integrated division of Walters Group that offers installation and erection services to the New York City market, has secured exclusive North American rights to use this new Self Climbing Kokoon technology. They recently deployed it for the first time on a 70-storey mixed-use high-rise that is part of the One Manhattan West Project on Ninth Avenue.
The Kokoon system provides a protective shell that moves with construction activity. Workers are shielded from the elements and protected from falls. The Kokoon creates a safe external walkway that allows workers to do bolt-up, detailing and decking operations easily and safely. In addition, the Kokoon protects tradespeople working on lower floors from falling objects. When workers finish one floor, the Kokoon moves with them to the next.
“Once the Kokoon is in place, we don’t require a tower crane or other major equipment to move it.” says Metropolitan Walters CEO, David Pisacrita. “It has its own power source and hydraulic arms. It only takes three people to move this 700-ton beast to a new spot.”
The Self Climbing Kokoon, developed by Italy-based demolition engineering firm Despe S.p.A., creates a curtain of steel that shields the active construction site from the elements. Demolition teams have used related technology before, but this cocoon is the first tool of its kind designed to be used during construction. Pisacrita was instrumental in re-designing this technology to work from the ground up.
“We firmly believe that worker safety and productivity go hand in hand.” says Pisacrita. “Metropolitan Walters makes it a point to be at the forefront of new technologies that enhance both these factors.”
