A critical lift plan must be prepared by a “qualified person” as defined by OSHA 1926.1401—an individual possessing a recognized degree, certificate, or extensive knowledge and who has successfully demonstrated the ability to solve problems relating to the subject matter. In commercial practice, this responsibility falls to Licensed Professional Engineers (PE) specializing in rigging, third-party PE firms, or experienced riggers holding NCCCO Rigging Level II or NCCER Advanced Rigger certifications.
For operations exceeding 75% of a crane’s rated capacity, utilizing multiple cranes under OSHA 1926.1432, or hoisting personnel at a maximum of 50% of rated capacity (governed by OSHA 1926.1431 and ASME B30.23), the ASME P30.1 framework requires rigorous engineering. The qualified planner calculates precise load weights, the center of gravity, dynamic loading factors, and exact ground bearing pressures.
Preparation is only the initial phase; the finalized document requires a mandatory multi-signature sign-off. The designated lift director, crane operator, and rigging supervisor must all review the plan for operational compliance, while calculations must be verified by a Qualified Person or PE before execution.
