Investigation Into Collapsed Building Will Be Done By Property Owners, Not City

Sioux Falls Emergency Manager Regan Smith says the investigation into what caused the former Copper Lounge building to collapse Friday will be done by the property owners, not the City of Sioux Falls.

Smith says the City is not conducting an investigation. He says the site has been turned over to the contractor.

Smith says it is still possible that debris may fall into sidewalks and streets. Barricades are still up and fencing will be placed around the former Copper Lounge building Monday.

It could be several days before the building is demolished.

The south wall tied into the former Copper Lounge building continues to be compromised. Property owners have hired their own structural engineers.

Smith says OSHA is expected to be in Sioux Falls this week for an investigation on worker safety.

The collapse killed 24-year-old construction worker Ethan McMahon and injured a 22-year-old woman.
