This webpage includes forensic engineering investigation reports of catastrophic incidents conducted by the Occupational Safety and Health Administration (OSHA), Directorate of Construction – Office of Engineering Services. Many of these incidents resulted in one or more worker fatalities, and property loss, lawsuits, or settlements of millions of dollars. Each investigation was performed at the request of an OSHA field office or State Plan OSHA as part of an enforcement inspection. These reports may include professional opinions of the investigating engineer; incident root cause opinions; factual data; and findings.

These investigative reports were prepared to assist the OSHA field office or State Plan OSHA. The alleged violations of standards referenced in the reports are findings and recommendations of the investigating engineer to assist the requesting office. The violations and findings recommended in the report does not constitute an OSHA violation of a specific party named in the report. The OSHA field office or State Plan OSHA may issue the recommended violation; additional and/or different violations of standards to the appropriate party. The final resolution of the enforcement case may result in changes to the initial proposed alleged violation(s).

The intent of these reports is to help employers, workers, construction engineers, project managers, and regulatory bodies identify problems in construction design, project management, and management of field engineering changes. Hopefully, this information will help reduce future incidents, fatalities, and serious injuries.

The web-version of the report may not include all photographs, schematics, computations, tables, figures, and other non-text items. Otherwise, the text of each report is identical to the original report. The report is maintained as part of the OSHA enforcement case file in the appropriate Area Office or State Plan.
