Mauerbau vs Bau
construction / building
'der Bau' and 'der Mauerbau' can both mean the process of building. 'Der Bau' is general and can refer to many kinds of structures. 'Der Mauerbau' is much more specific: it means either building a wall or, in historical texts, the construction of the Berlin Wall. The words can be confused because 'Mauerbau' is made up of 'Mauer' (wall) and 'Bau' (construction). The important point is: 'Mauerbau' only fits when a wall is really meant, or when referring to the historical event. For houses, roads, or construction work in general, you say 'der Bau'.
