As part of a BLS pilot project, the entire perimeter was surveyed in advance using a drone and modelled as a BIM as-built model. Based on this, the construction project model was also created from the planning data. These BIM models served as the basis for various tests relating to the use of BIM on the construction site. This allowed detailed collision checks to be carried out underground before the construction site. The slab book and drainage were automatically derived from the BIM models and made available on the surveying equipment as a basis for the paving work. Project CDE was used for documentation during the construction work and visualisation with augmented reality enabled a direct comparison between the planned and built state.
Objective of the Project
- Building experience and expertise in BIM at BLS
- Hardware and software layout for BLS BIM projects
- Analysing the BLS's existing data basis for BIM projects
Technical Data
- Project perimeter of 600 m, two railway crossings, 250 m drainage,
- Specialist models of the carriageway, signalling systems, traction current cable protection and utility lines and surroundings
- Building project model based on existing model
Special Features
- Connection to the existing DfA data
- Provision of models as IFC and via CDE
- Preparation of use cases with a focus on BIM on the construction site
- Realisation of project CDE trainings
Our Solutions
