Expansion of the fire alarm system (make Siemens) as part of the fire protection and energetic upgrading as well as the conversion and renovation of all floors of the main building of the Maximilian Kolbe School in Neunkirchen-Wiebelskirchen, which is sponsored by the Diocese of Trier.

The installation work will be carried out in 3 construction phases starting 20 working days after commissioning by the client until the end of 2023 (end of the 3rd construction phase), whereby the pollutant remediation (separate order) is carried out before the installation work of the individual construction phases in order to make the construction site free of harmful substances for the work of the other trades .

The work takes place during the individual construction phases, with the exception of the school holidays, during ongoing school operations.

The Maximilian Kolbe School was built around 1975 as a reinforced concrete skeleton construction (TT-beam ceilings on the ground floor and upper floors) or reinforced concrete / masonry construction (basement) with non-load-bearing system partition walls (so-called "Mechel walls") as interior walls and a curtain-type mullion-transom facade. The building has 5 floors (basement-3rd floor) and a technical floor. Due to the age, there are deficits in the building in terms of technical systems, fire protection, energy balance, etc., which should be remedied in the course of the renovation.

The expansion of the fire alarm system takes place in 3 construction phases and essentially includes the following items:

Fire alarm system (make: Siemens):

- Fire alarm center as a substation (1 pc),

- F30 standing cabinet (1 pc.),

- smoke alarms (approx. 270 pieces),

- manual call points (approx. 30 units),

- Fire alarm cable (approx. 3,500 m).
