Willis Tower

Willis Tower in Chicago, United States, by Skidmore, Owings & Merrill; Gensler podium renewal, rebuilt as an approximate visual BIM model from 3 published architectural references. The building measures 100 × 112 m on plan and 526 m tall, across 4 named levels: Lobby datum, Catalog rooftop — estimated, 103rd-floor Skydeck — estimated, Architectural roof.

Modelled detail includes nine bundled square structural tubes, stepped black-and-bronze facade and twin broadcast masts.

The template ships with 4 saved scenes — a street-level approach, 2 viewpoints from the building's own observation set, and an aerial three-quarter — and carries the real site at 233 S Wacker Dr, Chicago, IL 60606, USA, so map context and sun angles line up when you open it. It is an approximate visual reconstruction for design and presentation use, not a measured survey, certified BIM, engineering model or construction document.
