Parkhaus II Sengenthal

Project name: 
Parkhaus II Sengenthal
Project category: 
Commercial
Company: 
Max Bögl
Project location: 
Germany

Project data: Dimensions: 80 * 50 * 16m, 936 finished parts with about 10,000 t, 1,200 t in situ concrete

The head office of the German construction company Max Bögl in Sengenthal is extended by a multi-storey car park. The construction is based on BIM from entirely, which was one of the keys to success and lead to delivery two weeks prior to schedule.

A total of 936 finished parts with about 10,000 tons were modelled, 1,200 tons of cast-in-place used for foundations and 15 tons of steel structures for roofing and gable uprights for the parking house with 828 pitches. Max Bögl conducted the complete pre- and executional planning of the project and they tested also new BIM methods.

Accurate data model for improved quality

After the conceptual design, structural detailing of concrete and steel structures was carried out with the BIM software Tekla Structures. Because of the size of the project several models were created for use in different engineering teams. As a result, each team had access to all required information anytime. Teams used a Tekla BIMsight model for the coordination and mutual referencing.

Tekla Structures models were used also for the fabrication of precast, cast-in-place and steel structures. Drawings were derived from the BIM-Model, as well as data provided for the control of production machines. The model data was available for manufacturing in the form of BVBS, Unitechnik and NC and so could contribute to an increase in quality.

Visualized status and schedule planning

Max Bögl use the software Ceapoint desiteMD for project planning and scheduling. Tekla models were imported through CPIXML and provided with status information such as schedule releases, actual production, target completion or actual completion. A link to the schedule made a visual target-actual analysis possible.

Mobile status tracking of precast parts

On site, Max Bögl used an in-house developed app for mobile devices to track the precast status. With the app, it was possible to get status feedback of the manufacturing status of parts by scanning the component barcodes. For example, "Delivered on building site" or "on the axis A1 / A2 mounted". This information flows in desiteMD with all other status information together. The app made status tracking of parts from manufacturing to assembly available for everyone.

Model-based survey with Trimble Field Link

Max Bögl used Trimble Field Link along with the station Trimble RTS773 for the first time in the project Sengenthal II. With this system it is possible to stake out reference points from Tekla Structures on site and at the same time to play recorded actual points in Tekla Structures returns to determine any deviations. It is not a survey personnel necessary, the user is guided with Tablet and prism pole unerringly to the right positions. The system has proven itself in practice and the even the foreman on site could be fully convinced of benefits of the system after initial skepticism.

Benefits of BIM and Tekla in this project: 

  • Exchanges between planners through reference models
  • Measurement and survey link
  • manufacturing control
  • Current planning / project status for each participating visual
  • High reinforced project parts, for example, Consoles could be modelled reliably
