Ann Arbor is still waiting on Turner Construction Company to explain what caused a crane to collapse scaffolding on the 13th floor of the Rambler high-rise last week, and the company has paused removing the damaged equipment until it has a plan in place to prevent it from happening again.

A crane struck and collapsed scaffolding on the 13th floor of the Rambler at 701 Church St. around 12:30 p.m. Monday, Aug. 31. No one was injured. The incident sent construction workers home and triggered a city investigation of the 17-story student housing tower, which sits at the corner of Church and Willard streets across from East Quadrangle Residence Hall.

Workers were using the crane to move aluminum scaffolding when it struck a separate section, dragging it toward the edge of the building, where it bent and collapsed, the city of Ann Arbor said in a Facebook statement. A safety tether prevented the scaffolding from falling off the building. The scaffolding had previously been used to support curing concrete.

City building officials who inspected the site Tuesday, Sept. 1, said the incident was not a structural failure or collapse of the building itself.

Turner Construction Company, the project's general contractor, sent most of its crew home after the incident. Only workers needed to secure and remove the fallen scaffolding stayed on site. Further removal has been postponed until Turner puts a protocol in place addressing what caused the incident, the city said.

Chris McFadden, senior vice president of communications at Turner, told The Michigan Daily that no one was hurt and that damage was limited to temporary construction materials. MLive also covered the incident.

"We are committed to the safety of everyone on our project and the surrounding community, and this activity will resume only when we are confident it can proceed safely," McFadden said.

Video of the aftermath, posted to TikTok by user @katiekokas, had gathered more than 9,000 likes as of the Michigan Daily's report.

The Rambler is a 273-unit development with 1,009 beds ranging from studios to six-bedroom layouts, developed by LV Collective and designed to earn LEED Gold certification, according to the developer's project page. The project includes a $7.25 million contribution to Ann Arbor's affordable housing fund and is projected to open in fall 2027, according to the Michigan Daily.

The city has asked Turner to document the cause of the incident, the steps it will take to prevent a repeat, its plan for safely removing the remaining scaffolding, and details on the protective structure over the adjacent property. No deadline has been announced for that report.
