Pinnacle Industries uses Leica Geosystems Vertical Alignment System to keep super-tall building plumb in New York City

When the new Extell luxury high-rise building goes up at 217 W 57th St. in the New York City borough of Manhattan, the vertical alignment of the core-wall structure will be crucial to success. This internal core structure will rise almost 1,500 feet (460 metres) above the ground and will be the reference for all other building construction, making its construction one of the most mission-critical aspects of the entire project.

Pinnacle Industries, the concrete contractor responsible for building the structure, has invested in an innovative core-wall alignment system. Consisting of advanced GNSS and robotic total station solutions, the Vertical Alignment System from Leica Geosystems monitoring solutions will be used as each floor is constructed to ensure the overall vertical geometry of the structure. High-end training from Leica Geosystems will provide the support and knowledge transfer needed to achieve successful adoption of this innovative approach.

“It’s very exciting to be involved with the soon-to-be tallest residential building in the world,” Rutledge said. “Pinnacle is an industry leader in this type of construction, and we feel honored to have been selected by the team. Leica Geosystems’ solutions provide exceptionally high accuracy and outstanding performance, making them ideally suited for the high productivity demanded on projects like this. We’re thrilled to be able to play a supporting role in this significant and historic project.”
