Spider, a division of SafeWorks LLC, is providing suspended scaffolding and material hoisting solutions for the glass curtain wall and glazing installation on two towers of the World Trade Center — One World Trade Center and Tower Four.
Spider is supplying Portland-based glazing contractor Benson Industries with 12 complete swingstages to access the towers’ facades. Standard 20-foot and 30-foot modular platforms — powered by Spider’s SC1000 traction hoists — as well as Modulo platforms are enabling access to hard-to-reach areas. A custom modular outrigger beam monorail system was specially engineered to support the platforms.
In addition, four Beta Max Leo XXL VFD material hoists are being used to lift more than 3,000 massive glass panels into position. With hoists on each side of the building, installers carefully bring the large, delicate panels up at a rate of 40 to 80 feet per minute and precisely position for the install.
Spider’s New York Operation Center, led by operations manager Joe Simone and district sales representative Marc Frato, provided on-site, hands-on training to ensure safe operation of the equipment.
“From the minute the Spider team set foot on site to assess the project and explain our access and material hoisting options, we were confident they would provide the best solution,” said Frank Colletta, general foreman One World Trade Center. “And they have exceeded our expectations.”
“The reliability and flexibility of Spider’s equipment are essential for us to complete the upper portion of the project,” added Danny O’Brien, field superintendent with Benson Industries. “Their New York team provides great service, on-time deliveries, and helpful technical support to ensure that we are working safely at height, staying on schedule, and maximizing productivity. We couldn’t ask for more.”
“Spider takes pride in being an integral part of these high-profile projects,” said John Sotiroff, vice president Spider Sales and Distribution. “As the nation watches the progress of the iconic World Trade Center towers, Spider swells with patriotism and remains focused on keeping these and other quality contractors around the country safe at extreme heights.”
As Spider’s work on Tower Four nears completion, the equipment and focus has transferred to One World Trade Center which, at 1,776 feet, is the tallest building in the Western Hemisphere. Spider anticipates its phase of the project to be completed in September.
