What operation would NOT be included in construction activities?

Conducting safety training sessions for workers is not included in construction activities because it pertains to preparation and education rather than the physical construction process itself. Construction activities typically involve the actual building, installing, or repairing of structures.

Installing fixtures, undertaking repairs on previously constructed buildings, and completing the foundation of a new building are all direct tasks associated with construction as they involve tangible work that alters or enhances a physical structure. Safety training sessions, although crucial and necessary for ensuring a safe work environment, do not directly contribute to the construction of structures; instead, they aim to equip workers with the knowledge to perform their tasks safely and effectively.
