4-Star Hotel "Vier Jahreszeiten" in Kaprun-Salzburg

Because hotel operations could only be interrupted to a limited extent, we planned the window replacement floor by floor and in groups of rooms. We worked during the quieter off-season and handed each room back fully installed and cleaned before starting the next. The balcony doors were renewed in the same step. Some of the old openings were no longer true, which we accounted for during measuring so the new elements closed cleanly. This way the hotel stayed usable throughout, and the work was finished without any notable disturbance to guests.
