The cause of a roof collapse at a Rosslyn construction site is still not known, despite the incident taking place more than two months ago.
Patti Bell, a spokeswoman for the Virginia Department of Labor, said her department is still looking into the cause of the collapse.
“It’s still under investigation,” she said. “There will be no information until our investigation is complete.”
She did not give a time frame for the completion of the inquiry.
The collapse took place on Dec. 9. Crews from Clark Construction started pouring concrete on the top floor of JBG’s new Waterview office building located at 1919 N. Lynn St. at around 6:30 a.m. At around 8:30 a.m., a 60-by-30-foot portion of the 24th floor collapsed under the weight of the still-wet concrete, trapping workers and injuring 17, three of whom were in critical condition.
Workers from five unionswere working at the site through subcontractors, workers said. All 17 of the workers injured in the collapse were non-union employees of Clark Concrete, a subsidiary of Clark Construction.
All workers injured in the collapse have recovered from their injuries, said Clark spokeswoman Louise Pulezzi.
Workers at the site told The Examiner they did not think there was enough bracing underneath the floor to support the weight of the concrete, which one estimated at two and a half tons per square yard. This worker said people were avoiding the floor because of fears of collapse.
Pulezzi said work resumed at the site 10 days after the collapse occurred.
