BIM

At the beginning of every BIM project it is crucial to define the scope of the project. It is important to assess which built assets need to be scanned, which assets (if any) already exist in some form of BIM, but most importantly - what are the main purposes of digitizing the built assets. This can include the improvement of asset management, maintenance processes, optimization of energy consumption and many other applications. This helps define the level of detail (LOD) of the final model. This in turn helps define which scanning technology is adequate to apply for the scanning of your assets, how much work it will take to build the BIM model and which automations could help increase the speed and quality of the output delivery.

Once the scope of the project has been clearly defined, the built assets need to be scanned. Depending on the specifics of the assets, different technologies are applied to scan them and create a so-called Point-Data-Cloud. A Point-Data-Cloud allows us to take measurements of the assets in a very efficient way, respecting their geometries with very high precision. This can be done by different devices, some of which can be mounted onto a person’s body, others that can be attached to a drone and some are even built into mobile phones, or tablets. The application of them varies depending on factors such as desired LOD, accessibility of the assets and other factors. Yungo helps you acquire these scans and guarantees a high level of precision.

The scans of the built assets, which are typically acquired by laser scanning (Point Data Cloud) and/or photography are typically very large individual datasets of gigabytes, or even terabytes of data. These individual datasets need to be georeferenced, cleaned and matched together. We automate as many of these steps as possible to maintain a high level of quality and precision. Nevertheless, our engineers are still required to check the result’s integrity and to potentially adjust the automation(s) to acquire the desired result. This is something that our team of BIM-engineers works on closely together with our department of innovations. The outputs of this phase serve as a base for the final BIM-model.

Depending on the desired applications of the BIM-Model in the future, the pre-defined level of precision of the model and other factors, the digital environment which will store the BIM-Model and visualize it needs to be setup. This can include setting up and configuring a tool such as Revit, a database in which the point-data will be stored and potentially other software like your ERP, or facility-management tools which need to get linked to the model to allow for information exchange between the model and BIM-applications.

Once the scans are available and the digital environment has been setup, the 3D-modeling can begin. We strive to apply as many automations as possible to the modeling process. Especially for large projects we apply pre-defined asset libraries and machine-learning algorithms to identify individual built elements automatically and help us speed up the process of modeling, but also to reduce the amount of manual work, minimize human error and increase precision of the final output. A BIM-model is so much more than a georeferenced complex geometry. Yungo can enrich the 3D-model by various additional information specific the use-cases of your assets and workflows. This can include detailed material information, age of different elements, information about compliance and much more.

A BIM-model is a constant work-in-progress and therefore needs to get maintained. The information is mostly shared between different stakeholders. Whenever there is a change to any of the built assets the model needs to get updated to assure the integrity of the model towards the existing applications.
