BIM Technical Standards

  • 3D Imaging
    3D imaging, also known as laser scan or point clouds, is the process of recording existing conditions into 3D point data.
  • File Structure & Organization
    When creating new BIM data, how this data is divided and structured is important in ensuring project collaboration and in establishing the foundation for the building information life-cycle.
  • Grouping & Relationship
    For BIMs to be useful as more than a basic 3D model, they must contain an inherent hierarchical relationship structure.
  • MEP Color Mapping
    In an effort to achieve consistency across files, GSA has developed color assignments for MEP systems.
  • Minimum Attributes
    At an absolute minimum, the following non-visual data must be attached to model data.
  • Naming Standards
    There are two distinct ways in which BIM design software platforms manage files.
  • Parametric Components
    Parametric components are dynamically changed instance-based objects. These standards are applicable to all forms of these objects.
  • Referencing & Linking
    An external reference is any data that is viable yet does not reside within a particular file. The practice of referencing external data exists within all major BIM platforms.
  • Software Versions
    To ensure that all team members across BIM-enabled projects are able to have access to the model, here's a list of what versions of software are currently approved for use on BIM projects.
