Which term describes the inserting of the right amount of material into construction sites?

The term that describes the inserting of the right amount of material into construction sites is placement. This involves the careful positioning of construction materials, such as soil, concrete, or other aggregates, into specific locations to achieve the desired design and structural stability. Placement is a critical aspect of construction, as it ensures proper compaction and distribution of materials, which directly affects the integrity of the work being performed.

Excavation refers to the process of removing earth or other materials from a site to create a cavity or hole, rather than the insertion of materials. Filling typically means adding material to a space, but it does not encompass the precise and controlled action involved in placement. Hauling refers to transporting materials from one location to another and does not relate directly to the action of inserting materials into a construction site. Therefore, placement is the most accurate term to describe the activity in question.
