DENVER -- Regulators have proposed a total of more than $93,000 in fines for homebuilder D.R. Horton of Greenwood Village and four subcontractors.

The Occupational Safety and Health Administration said Monday it inspected a D.R. Horton work site in Parker and found subcontracted employees were exposed to the hazards of falling during framing and sheathing. OSHA proposes a $70,000 penalty.

OSHA also proposes a combined $23,640 in penalties for subcontractors Kellory & Co. Inc., Webb Construction Inc., Dain Construction Inc. and LBR Construction Inc., stemming from allegations of not enough protection from fall hazards during framing and sheathing and inadequate training on using forklifts.

"D.R. Horton failed to properly manage a residential project jobsite by allowing subcontractor employees to be exposed to serious fall hazards," said John Healy, OSHA's area director in Englewood. "This employer is well aware of the requirements for fall protection and has been cited several times for similar infractions."

The companies have 15 days to contest the citations.
