As the tallest single-use hotel structure in North America, 1717 Broadway takes its place alongside the many other prestigious projects in Navillus repertoire.
When completed, it will stand 70 stories tall. The structure required 12,000psi concrete in all walls and columns up to the 40th floor and 10,000psi concrete for the subsequent 10 floors. This use of this high-strength concrete at high elevations required the usage of complex chemical compounds, and therefore made the workability of the product all the more difficult. Despite these challenges, Navillus is able to pour the typical floors of this project with precision and efficiency in a 2 day cycle.
Being in the heart of midtown, on West 54th Street and Broadway and across the street from the Ed Sullivan Theatre, Navillus, as it always does, went the extra mile in ensuring a safe and healthy project for its workers and the public. As the first to use the Efco climbing safety system in New York City, Navillus installed this mesh cocoon system using aluminum steel members, allowing less inserts, which required less panels to climb, resulting in a quicker and more efficient jump time. The system is tied into the slab over 3 floors and provides 4 floors of protection.[/vc_column_text][us_sharing email=”1″ facebook=”1″ twitter=”1″ gplus=”1″ linkedin=”1″ pinterest=”1″][/vc_column][vc_column width=”1/3″][us_single_image image=”354″ size=”full” align=”center”][/vc_column][/vc_row]
