Installation of waterproofing materials requires the presence of which of the following?

The installation of waterproofing materials requires a licensed construction supervisor because this role involves oversight and coordination of construction activities to ensure compliance with building codes, safety regulations, and industry standards. A licensed construction supervisor has the training and knowledge necessary to understand the specific requirements and techniques necessary for proper waterproofing.

Waterproofing is a critical aspect of construction that prevents water intrusion and damage, and it often must be installed correctly to maintain the integrity of the structure. Having a licensed construction supervisor on-site helps ensure that the installation adheres to all applicable building codes and practices.

While other professionals, such as foremen or general contractors, may be involved in the construction process, they may not necessarily have the specific training or licensing required to oversee specialized installations like waterproofing. The certified architect's role typically focuses on design rather than on direct supervision of construction activities. Thus, having a licensed construction supervisor is crucial to ensure that the waterproofing is installed correctly and effectively.
