A critical lift plan must be approved by a person who meets both the OSHA definitions of Qualified Person and Competent Person—possessing the training, experience, and authority to oversee complex load handling. Per OSHA 29 CFR 1926.1432 (which applies specifically to multi-crane lifts) and ASME P30.1 standards, the Lift Director fulfilling both roles authorizes multi-level approval before any crane activity begins.
Before execution, the finalized plan requires formal sign-off from all key operational personnel. This typical approval panel includes:
- the lift planner
- crane operator
- lead rigger
- project manager
- site safety officer
Their combined signatures verify that site hazards, load calculations, and rigging configurations are fully vetted. Additionally, if the operation utilizes engineered rigging solutions or custom lifting devices, the critical lift plan must also bear the stamp and signature of a registered Professional Engineer (PE) when required by site-specific safety protocols or when utilizing custom-engineered lifting devices.
