What does cbr stand for in construction


The challenge in a BIM project is to use clear rules and a coordinated use of software to obtain “smart data” from “big data” in order to filter meaningful information from the data volume. Which information is useful for a project participant depends on his professional role. Everyone has a very specific view of the amount of data collected from the perspective of their specialist discipline, and they want to be provided with the information they need for their work as quickly as possible. In the BIM context, these contextual views are also referred to using the English term Model View Definitions (MVD) designated. In order for a project participant to be able to use the contextual view of their specialist role, it is not enough to simply collect the files that contain this data in one place. The data must be extracted, analyzed and structured. In addition to the technical context, the type of BIM data and its generation process also represent classification criteria that can be used to give the volume of data a structure.

Basically, a distinction can be made between the following types of data:

  • Geometric data (e.g. 3D models, plans, detailed drawings)
  • Alphanumeric data (e.g. room book, system book, component lists, specifications, calculation, text documents)
  • Calculation data (e.g. framework models, numerical simulation models FEM / CFD)
  • Process data (e.g. network plans, bar plans and their updating in the construction process)
  • Communication data (e.g. email, ticket systems, address lists)
  • Sensor data (e.g. photos, videos, 3D point clouds, groundwater monitoring, weather recording)
  • Metadata (information about other data e.g. author, date, version number, file format)
A characteristic of today's BIM software is that it is able to process data from several of the categories mentioned.
