groundworks

Below-grade construction work

Groundworks is the preliminary work done before main construction begins—excavation, foundation laying, drainage installation.

The term covers everything that happens at or below ground level before a building rises: The groundworks took three months because of the rocky soil.

In British usage especially, groundworks refers to this phase of construction as an industry specialty.
