Which tasks are allowed for an intermediate scaffolder?

The choice of cantilevered and spurred scaffolds is the correct response because these tasks require specific skills and a certain level of knowledge regarding the design and structural integrity of scaffolding systems. Intermediate scaffolders are typically trained to handle more advanced scaffold configurations that ensure safety and compliance with regulations. Cantilevered scaffolds, which extend beyond their support points, and spurred scaffolds, which are secured to a structure for added stability, necessitate an understanding of load capacities, balance, and safe assembly practices.

In contrast, tasks like building foundations, constructing roofs, and performing electrical installations generally require specialized training beyond the intermediate scaffolding level. Foundation work, for instance, involves significant structural engineering knowledge, while roof construction often requires training in working at heights and specific roofing techniques. Electrical installations involve understanding electrical codes and safety protocols, demanding qualifications that are distinct from those of an intermediate scaffolder. Therefore, the focus on cantilevered and spurred scaffolds aligns with the competencies expected of scaffolders at an intermediate level.
