Construction site negligence requires proving duty breaches through safety violations, inadequate training, or dangerous conditions. OSHA regulations establish safety standards, though violations don’t automatically prove negligence. Multiple contractors complicate liability determination. Site control, safety responsibility, and employee supervision affect duties. Common hazards include falls, struck-by objects, electrocution, and caught-between accidents. Documentation includes safety meetings, training records, and inspection reports. Expert witnesses explain industry standards and causation. Workers’ compensation bars employee suits against employers but permits third-party claims. Comparative fault considers worker safety rule compliance. Photographic evidence preserves dangerous conditions.
