Which task is NOT typically performed by a Qualified Intermediate Rigger?

The task of welding is not typically performed by a Qualified Intermediate Rigger because riggers primarily focus on the handling and movement of loads, ensuring safety during lifting operations. Their expertise lies in rigging techniques, understanding load capacities, and employing proper signals and communication during lifting activities.

Welding, on the other hand, is a specialized skill that falls under the purview of welders or fabricators. It requires specific training and certification distinct from rigging, concentrating on joining materials through various welding techniques, not the operation or management of lifting equipment and loads.

In contrast, dual lift operations, demolition, and modification of cranes are within the appropriate scope of responsibilities for someone qualified as an Intermediate Rigger. These tasks involve the manipulation of heavy loads, assessing lift plans, and applying safety measures, which align with a rigger's skill set.
