BIM - Digitalisation in project execution

BIM - Digitalisation in project execution

Data from the project execution is simply recorded.

Good documentation and communication of all processes that take place or are about to take place on the construction site and which are made available to all project managers on an up-to-date basis are of great importance for trouble-free construction progress. Such reports are very time-consuming for the people responsible, and the pressure on the construction sites often leads to data loss. By digitalising the project execution, it is possible to save up to 30% of time for such reports by automating workflows.

As part of the BIM implementation, we in the RSRG digitalise for the project execution including:

  • Development of a project management room to support construction and project managers: Digitalised workflows simplify documentation and presentation of relevant information.
  • Establishment of a Common Data Environment (CDE): for joint storage of documents, images and models
  • automatic machine controls for excavators and crawlers to improve accuracy and increase efficiency
  • and more


Through the project management room, all relevant information of the project is brought together in a "Single Source of Information" and made available to all participants in real time.

The project space solution supports everyday workflows (e.g. plan and model management, release request, quality and defect management, construction diary, etc.) and enables status messages, analyses and overviews, partially automated, and also strongly supports their creation.

The availability of project data (reporting), in future in real time, supports the management in controlling the project. Model-based machine control, automatic documentation through scans (such as through 360° cameras on the construction site), etc. will further optimise the construction site in the future.

In a second step, the project management room will be integrated into a Common Data Environment. The CDE connects teams, processes and information across organisational boundaries and supports the entire project life cycle.

The analysis of construction site processes enables a transfer of knowledge to upstream processes - in this way, disrupted construction processes in similar projects can in future be identified at an early stage and countermeasures/optimisations can be developed proactively.

BIM offers the following advantages:

  • Simplification of the construction site through digitalisation of workflows
  • Fulfilment of CDE customer requirements
  • Overview of project status due to dashboard
  • Simple, partially automated documentation and versioning
  • All stakeholders have the latest information

View into the future – BIM Maintenance

The BIM Maintenance area is also already under development. The aim is to continue monitoring objects such as the infrastructure of a railway facility during operation with condition data and thus keep the models created from the previous BIM phases up to date. Condition data can be generated, for example, through regular quality controls, targeted measurement campaigns or through permanent monitoring of elements.

It is also of central importance that after each intervention or change to a physical object, whether through renewal or maintenance, the BIM model is also adjusted and so kept up to date. An example would be quality records of our tamping machines after track adjustment has been carried out.

Analyses and forecasts are possible through regular monitoring. This allows maintenance or renewal measures to be more targeted, i.e. at the right time and in the right place. The life cycle of an infrastructure can thus be optimised, and costs can be saved. The necessary databases, e.g. the measurement database IRISSYS, which we use for different meter gauge railways, support these Life-Cycle-Analyses.
