A Sioux Falls construction company faces more fines for the 2016 building collapse that killed one employee.

The Occupational Safety and Health Administration issued additional citations Friday to Hultgren Construction. It says the construction company did not instruct employees to recognize and avoid unsafe working conditions. It is proposing penalties of $101,400.

Hultgren Construction was working on the building formerly occupied by the Copper Lounge at 10th and Phillips Avenue. The building was being remodeled for a new occupant, Lewis Drug.

The claim says Hultgren did not instruct employees how to properly support the multi-story building while they were removing an exterior load bearing wall between the ground level and first floor. On December 2, 2016, Ethan McMahon was killed while he was removing the last segment of the load bearing wall, which caused the building to collapse.

OSHA also says that employees were not instructed on how to monitor and ensure the stability of the building during demolition work or identify hazards that might appear due to weakened or deteriorated floors, walls or loose material. OSHA says that exposed employees to crushing hazards.

The report also says employees were not instructed on a safe method for removing a brick wall. Employees were allowed to start at the base of the wall section and work up to the ceiling. That allowed large sections of the brick wall to fall to the floor.

Hultgren Construction has 15 days to request a private meeting and contest the citations. If the citations are contested, the case would go before an Independent Occupational Safety Review Board.
