3D, 4D, 5D, 6D


Virtual Design and Construction (VDC) and Building Information Modeling (BIM) both refer to a fresh technological concept and procedural approach to project delivery at the center of which is the philosophy of creating a virtual counterpart of a building in a software solution. Such representation of the project is available in each design phases, and evolves as the design moves away from conceptual and into criteria, or detailed design. The virtual project model entails exact three-dimensional geometry of each building element or structural member, organized systematically and enriched will all relevant information which may be useful for various analyses, such as spatial relationships, quantities and properties of components and such.


A fully integrated, 3D, object-oriented project model, created by a BIM design authoring tool (such as Autodesk Revit™, or ArchiCAD™) is multi-disciplinary in the sense that it gathers designs and specifications of all stakeholders, including – architects, structural & MEP engineers and project owners. The approach fosters collaborative development and is one of the basis for practical integrated project development. Thanks to the abundance of stored information, the BIM model is ready to be analyzed and utilized and furthermore facilitates:

  • Constructability studies
  • Cost engineering
  • Clash detection & MEP coordination
  • Visual scheduling
  • Offsite prefabrication


BEXEL’s AEC professionals and consultants utilize VDC/BIM technology and internal processes and software technology to run virtual construction simulations and analyses to provide invaluable pieces information to our clients in real time, supporting their decision making processes with fantastic success.
