An Ghearmáin – Ventilation installation work – Anbau Unesco-Schule, 2. BA - Lüftung

Tógáil ar an Scoil UNESCO, 2. BA - Aeráid

(Note: I have translated the German text into Irish, preserving the procurement terminology, proper nouns, numbers, and units. The term "Anbau" is translated as "Tógáil ar" to convey the meaning of "extension" or "addition" in the context of a school building. The term "Lüftung" is translated as "Aeráid" to convey the meaning of "ventilation" in the context of a school building.
