Before a load is landed on it, who could a dogman receive information about the load capacity of a concrete slab?

• A. Site supervisor
• B. Engineer
• C. Crane operator
• D. The rigger

Answer: (B)

The essential idea is that the structural person who approves what a surface can safely bear is the one who designs and validates that capacity. For a concrete slab, the engineer determines the allowable load and any requirements for bearing area or spread to prevent damage. The dogman should rely on the engineer’s sizing and the lifting plan to know how much load the slab can safely take before landing. While the crane operator is concerned with the crane’s own limits, and the rigger with rigging setup, and the site supervisor with overall safety supervision, the slab’s specific capacity comes from the engineer. If there’s any doubt, the dogman should confirm with the engineer or refer to the approved lifting plan.
