Active networking of all persons involved in the construction project

Building Information Modeling (BIM) is a method for the optimised development, planning, execution and administration of buildings on the basis of digitalised product data. BIM applications place and link all building components and their data on a platform and create a digital building model, the "digital twin". All this happens in just one 3D model, on which all stakeholders work together. The real construction process is not started unless the virtual building meets all expectations and specifications.

The value chain for BIM encompasses basic research, preliminary and design planning, analysis and documentation, the manufacturing process including quantity calculation and scheduling, construction site management and facility management. The data can even be used for post-utilisation purposes such as demolition or refurbishment of the object.

BIM is much more than a digital building model

  • Building data model (5D): BIM is based on real data. Not only 3D geometry but also other important factors such as time and costs are represented.
  • Visualisation: BIM allows a realistic and better perception of the object.
  • Quantity calculation: The data model for the building enables an accurate and transparent representation of the required material quantities and a preview of the required capacities at any time.
  • Calculation: All costs at a glance: Costs for supplements can also be called up quickly and facilitate a decision.
  • Execution plan: Right from the start, all project stakeholders can plan the subsequent implementation in a very detailed way - even before the start of construction.
  • Collision check: Planning with regard to possible conflicts ensures smooth project progress and minimises delays and planning errors.
  • Construction management and control: Each project stakeholder always has an overview of the present status. Deadlines and trades are precisely coordinated by means of a construction sequence simulation. 
  • Cost control: BIM means cost transparency and cost security in the planning and construction phase.
  • Facility Management: The complete life cycle of the object is depicted in BIM and is the basis for excellent facility management.

Ready for BIM - the GFR workflow

We communicate our product data in the corresponding BIM portals based on VDI 3805 "Product Data Exchange in Technical Building Services". This means: DIGICONTROL automation systems can be easily embedded and deployed in all modern BIM applications.

GFR relies on BIM-compliant electrical planning with MicroStation by Bentley

We use MicroStation for BIM-compliant modeling of electrical planning within our building automation systems. MicroStation is the only CAD/CAE planning tool that comprises all specific modules for multi-trade modeling in building technology. Thus, we overcome the complexity of modern automation systems by means of a loss-free data exchange between specialist planners, builders and operators throughout all life stages of the project.

Added value thanks to BIM

  • All stakeholders can virtually enter, simulate, improve and fine-tune the construction project even in the planning phase.
  • This makes planning, implementing and managing construction projects faster and more efficient.
  • Errors in construction planning can be detected in a timely manner; new insights are saved in the system and can be used again for further projects.
  • BIM brings all stakeholders together on one platform and thus saves many coordination activities. Every change is automatically implemented in the entire construction plan.
  • Enhanced data quality, as they are all based on a common database and will be constantly synchronised.
  • Immediate and continuous availability of all current and relevant data for all stakeholders.
  • Improved exchange of information between stakeholders.
  • Continuous data processing throughout the entire life cycle of a building.

"BIM Impact" – Effects of BIM on different target groups

  • Construction companies will make early decisions on materials and contractors based on the information and offers provided in BIM.
  • Components or services of the individual companies can be combined as in a modular system or replaced by new suppliers.
  • BIM allows architects and planners, for example, to make direct decisions about service providers and materials.
  • Business conditions within the construction industry are changing: designers and planners will be in direct contact with manufacturers of building materials.
  • Retailers should re-evaluate their business models and, for example, establish themselves on the market as providers of modular construction kits for holistic building material solutions.
  • General contractors and building material dealers will significantly lose influence, as the material and product decision in the construction process will be shifted further and further forward.
  • BIM is increasingly becoming the standard for the entire construction industry. Without access to the system, companies will be forced out of the market in the medium term because they are not visible on this platform.
  • BIM is not just a matter of using digital tools, but of digital corporate transformation.
