McLaren Engineering Group provided structural engineering on four cable net walls located on One World Trade Center in downtown New York City. Each wall standing at more than sixty feet tall provides a grand entrance to the newest, tallest building in North America. The walls are supported on all sides by six-foot-wide stainless steel jamb plates and a two-way cable net of pre-tensioned cables.
The structure required hidden connections and tolerances less than one quarter of what is typically allowed for steel construction – creating engineering challenges for McLaren to overcome. From the spider fittings made in Germany, to the high strength stainless steel bolts, nearly every piece of the structure was custom designed and fabricated to account for the temperature differences between the indoor temperature at the shop and the outdoor temperature at the site. McLaren’s attention to detail and experience with large scale, fast track, architectural structures provided a constructible design true to original intent.
