A specific, time-limited stage during the construction of a building, a road, or another facility. A construction project is typically divided into several such phases.
example
Das Haus befindet sich noch in der ersten Bauphase, der Rohbau ist noch nicht fertig.
The house is still in the first construction phase; the shell construction is not finished yet.
Usage tips
Word composition
The word is made up of 'der Bau' (construction) and 'die Phase' (phase/stage). So it literally describes a stage during building, which makes the meaning very transparent.
EXAMPLE
Wegen des schlechten Wetters verzögert sich die aktuelle Bauphase.
Because of the bad weather, the current construction phase is being delayed.
Typical prepositions
To describe a state, the preposition 'in' is used with the dative. To express the transition into a new stage, 'in' takes the accusative.
EXAMPLE
Das Projekt befindet sich in einer kritischen Bauphase.
The project is in a critical construction phase.
Typical collocations
Common adjectives are 'erste' (first), 'letzte' (last), 'nächste' (next), or 'entscheidende' (decisive) Bauphase. Typical verbs are 'eine Bauphase beginnen' (to begin a construction phase), 'abschließen' (to complete), or 'einleiten' (to initiate).
EXAMPLE
Die letzte Bauphase umfasst die Gestaltung der Außenanlagen.
The last construction phase includes designing the outdoor areas.

Bauphase vs Bauzeit
construction period
'die Bauzeit' and 'die Bauphase' both have to do with the time during a construction project. 'Bauzeit' usually means the total duration needed for the construction. 'Bauphase', on the other hand, means a specific stage within the project, for example 'der Rohbau' (shell construction) or 'der Innenausbau' (interior finishing). They can be confused because both words express time. If you are asking about the length of the entire construction project, 'Bauzeit' fits. If you are talking about one part of the process, 'Bauphase' is more precise.
Bauphase
In der nächsten Bauphase werden die Fenster und Türen eingesetzt.
In the next construction phase, the windows and doors will be installed.
Bauzeit
Die Bauzeit für die neue Brücke beträgt ungefähr zwei Jahre.
The construction period for the new bridge is about two years.
