Acting on a complaint in June 2016, OSHA inspectors found employees of one of the area’s largest general contractors working in an unprotected 10-foot deep excavation at a suburban New Jersey high school, in violation of federal safety and health laws. OSHA has issued citations for nine violations  – one willful and eight serious – to the Landtek Group Inc., a New York-based general contractor that specializes in sports facility design and construction.
