The right BIM Solution

BIM Guide for Germany

The BIM Guide is of interest for all in Germany having to do with the BIM method. It offers a first introduction to the BIM topic and to the requirements that have to be met within an office or during a construction project when introducing BIM as a new way of working.

Building Information Modelling [BIM] has gained a lot attention abroad already. Even in Germany the need for and the interest in information on how to deal with this topic is growing. There is a lot of interest in topics like the influence of BIM on the traditional planning processes, the initial problems that have to be expected or the definitions of new responsibilities and roles. The key question raised however is about the overall benefits of BIM to the project execution and the particular benefits to the various participants.
Another important topic is how BIM has to be implemented in the different fields:

  • How does the client have to phrase the BIM requirements for the different parties involved in the construction project?
  • What do designers and engineers have to know about the BIM method to be able to collaborate more efficiently and to offer to the client a BIM based project execution?
  • How do the construction companies have to deal with BIM?
  • What new way of information delivery does BIM offer product manufacturers?
  • How can Facility Management profit from it?
The advantages that the BIM method offers to all project participants are most decisive when it comes to implementing BIM at a greater level. The BIM method has one big goal: To increase the project information's quality, up-to-dateness, and transparency in order to guarantee a project's main goals as cost-effectiveness, sustainability, or budget and schedule reliability.

It's quite a common assumption still in Germany that BIM is a method only for larger projects, big offices and construction companies. But in contrast to that this guide also shows the usage in small and medium businesses and thus in structures that are typical for Germany. The approaches towards implementing BIM vary in regard to the project sizes, but in all cases an added value can be achieved by utilizing the BIM-method the right way. Another assumption raised by newcomers is that BIM will lead to higher overall design costs, but there was no evidence proving this. It is however well acknowledged that BIM will lead to a shift of efforts and costs from the later to the earlier project phases.

The BIM guide provides an understanding of the way to work with the specific discipline models and the strategy on how to coordinate and manage a BIM-based project. This BIM guide provides information on how to go about the mostly 3D discipline models, their levels of detail and the comprised BIM model elements.
Other important topics are the collaboration across the different disciplines:
  • the way decision making has to be coordinated,
  • the new arisen roles and responsibilities and
  • the necessary new educational profiles.
The BIM-based coordination processes and the usages, such as visualisation, creation of consistent drawings and schedules, model-based quantity takeoff and simulations, and collision checking are described in more detail. It requires highly efficient interfaces to coordinate the dataflow across different (software-) platforms and to the client. While concentrating on IFC this guide describes and evaluates them.

In consequence BIM means a change in the way project will be executed at several levels, the coordination processes, the organisational structures, and the technology uses, all leading to a more collaborative way of working. The BIM guide includes several appendices comprising data sheets and check lists that can be used in preparing for the utilization of BIM in offices and projects.

The BIM guide for Germany was provided within the scope of the research initiative "Future Building" by order of the Federal Institute for Research on Building, Urban Affairs and Spatial Development by OBERMEYER Planen+Beraten & AEC3 Germany.
