Two companies face fines for a deadly construction collapse at Argyle High School earlier this year.
The Occupational Safety and Health Administration is fining Northstar Builders Group, LLC, and Warnick Metal Building Erectors, Ltd., $7,000 each for the collapse.
In April, a building under construction collapsed, killing 36-year-old Julio Ledesma and injuring three other people.
According to the OSHA citation issued to both companies, the violation is considered "serious," and the federal investigators said the companies did not maintain structural stability of the building.
Less than a week after the collapse, a worker at the Argyle High School site was killed when he was struck by an 18-wheeler. No OSHA standards violations were found and no citations were issued in that case, officials said.
