Munich Airport fire brigade relies on Herchenbach temporary building

Interim solution with potential for permanence
To bridge the period of reconstruction, fire station north at Munich Airport needed a place to park four fire brigade vehicles. The choice was made for a Herchenbach temporary building. This solution was apparently very convincing: After the completion of reconstruction, the building Flughafen München GmbH had originally hired from Herchenbach for a year was bought, with the intention of continuing to use it long-term.

"Fire brigade vehicles prefer a place where it is dry and warm," emphasizes Eugen Kroneberger, of deployment direction services of the Munich Airport fire brigade. "Not just to prevent the fire-fighting water from freezing in winter, but also because cold temperatures are not ideal for the engines, which need to be driven at full throttle right after starting." So when some of the vehicle buildings can't be used, like during the reconstruction of fire station north at Munich Airport, a replacement has to be found. "That is the only way to ensure that all vehicles are fully operational at all times for an emergency," adds Kroneberger.

Weather protection like a permanent building

Modern temporary buildings can act as the ideal shelter, because they can be set up economically and quickly. High quality buildings, such as the Herchenbach firm's Heba-Fix® line, not only offer weather protection and benefits comparable with a permanent building, they can also be adapted in terms of size, format and features to the needs of fire brigades or other municipal fleets. Without a lot of involved preparation, they can be quickly set up and dismantled again on a variety of substrates

The building Herchenbach built for Flughafen München GmbH measures 20,00 x 15,00 m (Building Sizes) and is in the direct vicinity of fire station north. It has a saddle roof with a height at the eves of 5 meters, so particularly tall vehicles can pass through without any difficulty. On the length side, four 4 x 4 m sectional roller gates with a transparent section are installed. As such, it is possible to see from the outside whether there are any vehicles inside. When the vehicles are dispatched to an emergency, the gates open electrically with the push of a button – as is typical for a fire station building that houses the vehicles – and close again automatically after being triggered by a light barrier.

Assembled and ready for use in seven days

With the exception of the building permit, the entire building was supplied ready-for-use, so all work was performed by Herchenbach – from surveying to static plans and ground testing, right to transportation and assembly with Herchenbach's organising the scissors lifts too. "The assembly of the building took only seven workdays," says Kroneberger, explaining the process. "Notable is also that Herchenbach provided documented proof of the necessary security and training certificates for all the installers involved in the project. These are a requirement for work in the security zone of the airport."

After measurements and ground testing, the installation experts first installed the support structure made of aluminium profiles. The length of the pillars was adapted to compensate for the slight slope of the ground. The building's pillars are fixed to a steel base plate and stand directly on the asphalt – anchoring is with earth pins. The advantage of this is that the building can be quickly set up and dismantled again without involved foundation work, so no traces are left behind.

Fully insulated building shell

Of high importance to the fire brigade was protection from the elements and insulation. The roof of the building is made of a long-lasting, insulated Heba-Therm® industrial tarpaulin. It features a U-value that would usually only be found in a permanent roof. An additional inner tarpaulin catches potential condensate and conveys it to the outside of the building where it is fed to the drainage system. The wall consists of thermally-insulated sandwich panels with a U-value of 0.3 W/m2 K. With that, the entire building shell is thermally insulated. Combined with an air-blower heater, it is ensured that the temperature inside the 300 sq.m building never drops below 10 degrees Celsius, even during harsh Bavarian winters. Sealing is applied all round the building walls, so moisture and drafts cannot penetrate.

Re-use at a new location

After standing for the planned twelve months, reconstruction work at fire station north was completed, so the temporary building wasn't required there anymore.
"However, the building solution supplied by Herchenbach was so convincing that we bought the originally hired building and put it to use at a new location," says Kroneberger. "There it is likewise put to use to house vehicles, but not just for the fire brigade."

"The fact that our customers first lease our buildings for a specific project and then decide to keep them, is something we experience quite often," says Managing Director Tobias Raeber. "Especially in situations where there is a need to find an economical solution to shelter vehicles or equipment; as permanent solution, our comparatively cheap buildings with their service life of 25 years at a minimum are ideal.“
