Ready to go with sophisticated freeform architecture
A visionary innovation center is being built on the grounds of Munich Airport: LabCampus. With its direct connection to the international transport hub, Bavaria is becoming even more attractive as a business location. Over the next few years, four quarters with modern office space and varied architecture will be gradually built on an area the size of around 70 soccer fields in the north-west of the airport.
The new AirportAcademy building is already the second building by the Auer Weber architecture firm on the LabCampus for which Ed. Züblin AG is responsible as general contractor. The five-storey training building with a length of 76.40 m, a width of 49.40 m and a gross floor area of over 15,000 m² will be used as a training center for Flughafen München GmbH from the end of 2022.
Airport runways as a circumferential framework
The defining trademark of the new training center is the surrounding concrete framework over two floors. This formative exposed concrete element reflects the - viewed from above, unique - runway geometry of Munich Airport. Despite the filigree appearance with its opening function, the 10 m high and a total of 250 m long truss band supports the upper three storeys. In the interplay with the glass facade of the base storeys attached behind it, the geometrically extremely demanding concrete construction with its nested inclined struts is clearly visible from the outside and inside and was therefore to be executed in high exposed concrete quality.
Combined project-specific: system and special formwork
The ZÜBLIN construction team uses the formwork and scaffolding systems from PERI, for example the MAXIMO and VARIO GT 24 wall formwork as well as PERI UP shoring and the PROKIT fall protection. The decisive factor for the positive course of the project, however, are the large-format recess boxes, which were individually manufactured by PERI as project-specific dimensional elements for the production of the extraordinary concrete framework. In total, the PERI engineers at the Munich branch in cooperation with the Weissenhorn assembly specialists delivered 89 of these molding boxes to the construction site as planned and pre-assembled at the factory.
Using the VARIO GT 24 girder wall formwork as well as PERI UP shoring and working scaffolding, the truss inclined struts including the nodes and the upper chord could be formed and concreted in 3 sections with a pouring height of 3.67 m, 3.20 m and 3.07 m each become. Despite the differences in all struts and connection points, some of the special elements can be used several times at different locations, as the possible arrangement of the individual tie points was already taken into account during planning and production. In addition to the dimensionally accurate geometry, the clear identification and the integrated crane attachment points were also part of the PERI solution.
Planning + logistics = quality + profitability
The ZÜBLIN project managers headed by chief construction manager Friedrich Rauch worked closely with the PERI formwork specialists in the early bidding phase. In this way, it was possible to jointly design an implementation solution that could later be implemented 1: 1 as planned. Always with the declared aim of minimizing the material requirement, i.e. the number of special elements, as far as possible while taking the construction process into account. The interplay of planning services, technical production quality and timed logistics ultimately led to the desired success of achieving high concrete quality with economic means. In addition, the PERI project coordinator supported the construction management in close cooperation with the implementation. As a competent contact person for all technical, commercial and logistical tasks, he coordinated the planning, managed the timely provision of materials and constantly adapted them to the actual construction process.
