Pixel2Pset
As in many of our projects here an innovative digital development was implemented directly in the project.
The project A99 for the Autobahn GmbH des Bundes NL Südbayern and StrucInspect comprised the establishment of a BIM-based digital structural inspection model for the existing bridge structure BW32/1 at the motorway ring Munich. The requested as-built model was in a quality of LOD 500 and generated via a scatterplot-based scan-to-BIM-process with information from the available reinforcement plans and test reports.
To be able to implement this task in an optimized way, a client-specific software tool for automatic generation of a structural inspection BIM model was developed, which was exclusively derived from the alphanumeric data of the digital structural inspection. In addition, a custom-made Python IfcOpenShell tool was developed to automatically convert the raw ASCII data, which were issued from digital inspection into a highly detailed informative IFC4-model and a corresponding BCF-damage catalogue.
We are very proud of our colleague Peter O'Brien, who was able to win the buildingSMART International Award with a unanimous jury assessment for his submission in the category technology. Here is a short video, in which he presents his innovative workflow of "Pixel2Pset".
Wakrah – Wukair
Drainage Tunnel Doha, Qatar
The project, located in the southern part of Doha near the municipalities Wakrah and Wukair, is part of the wastewater network of these sites. The project comprises the design and the construction of a 13.3 km long TBM drainage tunnel in double-shell construction method with an inner diameter of 4.5 m in a depth of up to 61 m as well as eight access ducts and down structures. All of them are parts of the wastewater network Wakrah – Wukair and Industrial Area.
The digital engineering challenge that had to be solved in this project was an efficient and automated generation and positioning of tubbing segments as a basis for the tunnel boring machines. This was managed via programming of a simulation tool in C# and the development of an API-plugin in Autodesk Revit. Thanks to this automated version different iterations for optimized planning could be simulated in only a few seconds via the development of an algorithm.
At the beginning of 2022 the two tunnel boring machines with a boring diameter of 5,885 mm were successfully started. Both TBMs are expected to drill the 13.3 km long tunnel by May 2023. Design is completely performed by applying the method Building Information Modelling (BIM).
