What Is a Rigging Plan?


Quick Answer

A rigging plan is a safety protocol developed by construction workers every time they lift objects of significant weight. When producing such plans, workers typically attempt to determine what class load they are elevating. The three most common types are ordinary, critical and pre-engineering lifts.

Full Answer

Rigging plans try to consider all the safety precautions relevant to a specific situation, including the weight of the lifted mass, the rigging equipment available, the height, width and length of the lift, as well as the lift's center of gravity. Additionally, planners try to anticipate, calculate and avoid serious complications resulting from the lift, such as drops or collisions that may put people, structures, property and even the lift itself in danger.

Ordinary lifts are the easiest and most common form and typically require only a verbal exchange between planners and a test hold to make sure the rigging is adequate. Critical lifts require far more planning and often entail a written plan for the procedure, along with supervisor approval. Pre-engineering lifts are the most complicated, often requiring detailed individual rigging points. Before any rigging plan is executed, all the critical personnel, including the person-in-charge, rigging leader and crane operator, are formally identified. Additionally, the lifting zone is inspected for potentially hazardous conditions, and any obstructions removed.
