March 22, 2007 Creating a structure as spectacular as the new U-shaped Grand Canyon Skywalk observation platform requires reliable engineering - visitors will be standing on all-glass flooring suspended 4,000 feet above the Colorado River. The architect's vision is that visitors will have the sensation of floating freely without the intrusion of visible supports and can enjoy a panoramic view. The graphic shows the height of the Grand Canyon Skywalk compared with the world’s tallest buildings. The Skywalk opens March 28 when visitors will be able to scare themselves silly looking between their feet, through two inches of ultra-clear DuPont SentryGlas Plus structural interlayers and onwards to the depths below them. The DuPont material provide strength and stiffness plus optical clarity for the all- glass flooring that enables visitors to have an unprecedented viewing experience while standing safely on the observation platform. Analysis done by DuPont; the glass supplier, Saint-Gobain; and structural engineering consultants show that the laminated glass floor can hold the weight of up to 120 people and maintain a top safety rating even in the face of 100 miles per hour winds.
