A drilling rig toppled at the construction site of Citadel's planned $2.5 billion global headquarters in Miami on September 14, injuring four individuals and damaging several vehicles. The incident, which occurred near SE 12th Street and Brickell Bay Drive, involved an 85-foot drilling rig used for soil-improvement work, not a conventional construction crane as initially reported. Three construction workers, aged 27, 29, and 47 (the rig operator), along with a motorist, were hospitalized with minor injuries.

The rig struck three vehicles and crushed a construction container, trapping two workers inside who were subsequently freed by rescue teams. Firefighters also extinguished a vehicle fire, specifically a white BMW SUV that caught fire after being hit. The U.S. Occupational Safety and Health Administration (OSHA) has launched an investigation into the accident, and Miami-Dade County records identify Keller North America Inc. as the soil-improvement contractor at the 1201 Brickell Bay Drive site.

Citadel, developing the project with Related Companies, stated that its development partner is cooperating with city and county building departments to secure the site and investigate the incident. The accident has temporarily disrupted early construction work for the 1.7 million-square-foot tower, which is slated to be Citadel's future global headquarters, housing approximately 1.2 million square feet of office space, a luxury hotel, and other amenities. The project, valued at $2.5 billion, has seen Ken Griffin, Citadel's founder, spend over $770 million on land acquisition.
