Three workers were hospitalized after suffering non-life-threatening injuries when scaffolding collapsed at a Green Farms Academy construction site Thursday morning.

The workers were injured shortly after 10 a.m. when scaffolding -- about 25 feet high and 100 feet across -- gave way at the private school on Beachside Avenue, according to Alison Freeland, the school's director of marketing and communication.

"The construction project is for four global studies classrooms and a new performing-arts center," she said. "Initial word is that it was due to the high winds this morning."

Four construction workers were checked at the scene by emergency medical personnel, and three of them were transported to Norwalk Hospital for treatment of non-life-threatening injuries, according to fire officials.

The state Occupational Safety and Health Administration and town police and fire officials started an investigation into the incident following the collapse.

"The construction site is completely fenced off, so no students or faculty were affected by the incident," Freeland added.

She said the building project is expected to be complete in the fall.
