About Inspection Records
Inspection records are public documents maintained by the U.S. Department of Labor. They provide a transparent account of federal workplace safety enforcement, including what was inspected, what was found, and what corrective actions were required.
Current penalty amounts shown on this page may differ from initial assessments. OSHA adjusts penalties based on employer size, good faith compliance efforts, and violation history. Employers may also negotiate reductions through informal conferences with the OSHA Area Director.
About This Industry
NAICS 238910: Site Preparation Contractors / Construction
This industry comprises specialty trade contractors primarily engaged in site preparation activities such as excavating, grading, land clearing, demolition of buildings, and wrecking. Blasting and drilling for construction are also included.
Common workplace hazards include struck-by incidents from heavy excavation equipment, trench and excavation cave-ins, and exposure to underground utilities. Workers may also face risks from demolition debris, asbestos and lead in older structures, and vehicle traffic in active work zones.
OSHA's Focus Four identifies the four leading causes of fatalities in the construction industry: falls, struck-by incidents, electrocution, and caught-in/between hazards. Together these account for the majority of construction worker deaths each year. OSHA's construction standards under 29 CFR 1926 specifically address each of these hazard categories, and they are a primary focus of programmed construction inspections.
Data Source and Methodology
Data synced dailyData on this page comes from the U.S. Department of Labor's OSHA enforcement database, accessed via the DOL public data API. Records are updated daily. We strive for accuracy, but errors in data processing or establishment grouping are possible. Penalty amounts reflect the latest penalty amounts on record in the DOL database and may differ from initial assessments or final amounts after informal conference, settlement, or judicial review. Company pages group inspection records by normalized employer name, city, and state as reported in OSHA records. That grouping is deterministic and non-fuzzy, but it is not a universal legal-entity identifier. If you believe any record is inaccurate, please report it and we will investigate.
