OSHA is proposing $166,000 in penalties against Concrete Express Inc. (CEI) of Denver for unsafe working conditions following a July 5, 2007, partial collapse of a concrete floor that injured 13 employees.

The employees were involved in the construction of the Landmark Tower condominium project in Greenwood Village, Colo., when shoring, concrete and formwork collapsed, and the employees fell to the floor below. The general contractor on the site was Beck Residential, which contracted with CEI to provide shoring and formwork for support of the concrete frame of the building.

OSHA's Englewood Area Office issued two willful violations with proposed penalties of $140,000 for a structural collapse hazard and improper shoring and bracing. Six serious violations with a proposed penalty of $26,000 cover employee exposure to collapse, fall and tripping hazards.

CEI plans to meet with OSHA's area director Jan. 24 to discuss the violations, according to the Associated Press.
