Four workers were injured, one critically, after part of the steel framing in the partially built equine center at Texas A&M University collapsed on Saturday.
A portion of the 300-foot-long structure being built in the 3500 block of F&B Road came down around 10.50am, the College Station Fire Department said.
Units from the College Station and Bryan Fire Departments, and Texas A&M University Emergency Medical Services (EMS) were notified at 10.49am that the building, part of a new equine center, had collapsed, injuring several workers.
The first fire unit arrived at 10.55am and reported that four workers were in the collapsed area.
They were removed to local hospitals by 11.18am.
At that time, search and rescue efforts were suspended until the rest of the structure that was still standing could be stabilized.
After the structure was secured, a secondary search of the area was conducted to ensure that all workers had been located.
The situation was deemed under control at 11.56am. There were no other injuries reported.
The incident is under investigation by Texas A&M University Police Department.
The injured men were taken to St Joseph Regional Health Center in Bryan.
One man, 35, was admitted in critical condition. Two men, 22, were admitted and reported to be in a stable condition. A fourth man, age 32, was treated and discharged.
The workers were understood to be attaching steel beams to the existing structure from a lift 40 feet above the ground when the collapse occurred.
The steel structure formed the frame for a new 300 feet long barn, part of the work on the new $US80 million equine center which began last October. It is scheduled for completition late this year.
A total of 13 units comprising 33 personnel from the College Station and Bryan Fire Departments, and the Texas A&M University EMS, responded to the call.
