Firefighters rescued a construction worker who was injured by falling concrete while 15 feet below ground in a trench at a country club in Lake Forest Friday morning.

The Lake Forest Fire Department responded around 9:58 a.m. Friday to the Onwentsia Club, 300 North Green Bay Road in Lake Forest, for a report of a traumatic injury.

Lake Forest Deputy Fire Chief Andy Rick said firefighters arrived to find a construction worker at the bottom of a basement foundation under construction.

The worker was injured and approximately 15 feet below grade.

Crews found a concrete form had fallen from scaffolding and struck the victim, causing a back injury, Rick said.

The Mutual Aid Box Alarm System (MABAS) was activated to the box alarm level for additional fire crews and equipment to the scene to assist in the rescue.

The patient was treated and prepared for removal from the trench by paramedics, Rick said.
