Office Towers and High-Rises

ADF Group has successfully delivered several projects for the design and engineering of connexions, the fabrication and the installation of steel structures and complex and heavy steel built-ups for high-quality office towers and skyscrapers in North America, including more than a dozen in New York alone.

Several of these multipurpose buildings house offices, condominiums, shops and restaurants, as well as some spectacular large halls, which usually feature specific geometry and architecture and are subject to special requirements and strict tolerances.

This multi-use high-rise is made up of three structures: the first section is a 54-story tower with a 9-story podium, housing a hotel and condominiums; the second section consist of second podium of 8-story, housing retail stores and offices; and the 6-story canoidal shape (or sloping ellipse) core section connecting both podiums features an atrium with a roof skylight.

The heaviest steel built-ups with multi-connection nodes fabricated by ADF weigh 32 tons each and were installed between the building’s 28th and 31th floors, which precede the upper concrete floors.
