Tiefbau vs Strassenbau
road construction
'der Strassenbau' (road construction) and 'der Tiefbau' (civil engineering) both belong to the field of construction and often involve work at or below the earth's surface. 'Der Strassenbau' is more specific: it is about roads, paths, and squares. 'Der Tiefbau' is broader and also includes tunnels, sewers, or other structures underground. The words can be confused because road construction can be part of civil engineering. If it is specifically about a road, 'Strassenbau' fits better. If several types of construction work in the ground are meant, 'Tiefbau' is more natural.
Tiefbau
Im Tiefbau plant das Team neue Kanäle und eine Unterführung.

Strassenbau
