The fire brigade of Mechelen recently moved into a new firehouse on the Nekkerhal on a site of approx. 21,000 m². Lybover FIRE designed and installed the smoke and heat extraction system.

The Lybover way

Three contractors submitted tenders for the construction of a new fire station in Mechelen. The contractor Van Roey won the DBFM project. For the fire protection of the fire station, contractor Van Roey in turn submitted a broad price request. Lybover FIRE came out on top by proposing a customized smoke and heat extraction system that meets all legal requirements.

We chose Lybover FIRE because they put forward the best idea and searched with us for the best solution

The new building not only houses the fire brigade, but also the execution services of the city of Mechelen. The building consists of four parts: the office building, the joint entrance for the fire brigade and execution services, the stabling area for the fire brigade vehicles and a parking building. A five-storey office building has been built for the administration of the Rivierenland rescue area. The office building meets climate ambitions and is a NEN (Nearly Energy Neutral) building. Next to the office building, a large vehicle hall for 24 large intervention vehicles will be built. For the depot, Joël Verpoucke, Sales Engineer for Lybover FIRE, developed a concept that avoids boosters and fans. He provided a natural smoke and heat extraction system instead. Together with Van Roey, Lybover FIRE defended this design to the fire brigade. The idea was warmly welcomed by both the fire brigade and the architectural firm, as it enabled the interior space to be completely free of fans.

Thanks to Lybover FIRE, we were able to bring technology and aesthetics together

CFD simulation confirms proposed solution

On the other side of the office building is a two-storey car park. The ground floor has been made completely frost-free for 60 large service vehicles, such as cleaning vehicles. On the first floor there are about 70 service vehicles stationed and on the second floor there is room for about 125 passenger vehicles of the employees of the city services and the fire station.

Originally the intention was to compartmentalize the car park with internal walls, but Lybover FIRE proposed to work with one large central smoke screen and 10 axial fans D1600. This concept not only saved space, but also solved some architectural difficulties. To ensure that this was the ideal solution in the event of a fire, a CFD simulation was carried out. This simulation confirmed that the chosen solution would achieve the desired result.

Within the timeframe set

The complete realization was led by Jan Lobbestael, a volunteer fireman and project leader at Lybover FIRE. He worked on this project with great passion. Together with Thijs Van de Velde, Technical Designer, and Joël Verpoucke, Sales Engineer Projects, he ensured that the timing was respected. Together with the architect, he did everything he could to request a deviation from the committee of internal affairs.
