Chapter 21 provides a framework for understanding the BIM software landscape without endorsing specific brands (which would quickly become outdated). Instead, the authors categorize tools by function.
Authoring tools: Used to create BIM models. These include architectural, structural, and MEP (mechanical, electrical, plumbing) applications. Key selection criteria: discipline focus, file format support (native and IFC), parametric capabilities, and learning curve.
Review tools: Used to combine federated models from multiple authoring tools, perform clash detection, measure distances, and create reports. Review tools typically offer better performance for large federated models than authoring tools.
Collaboration platforms: Provide the Common Data Environment (CDE) functionality—version control, access permissions, audit trails, issue tracking, and model viewing in web browsers. These platforms often integrate with other project management software.
Analysis tools: Perform discipline-specific simulations: energy analysis, structural analysis, lighting analysis, acoustic analysis, fluid dynamics (for airflow or water flow), and pedestrian movement simulation. Analysis tools typically import IFC models, run simulations, and export results back to the model.
Quantity takeoff and estimating tools: Extract quantities from BIM models (volume of concrete, length of piping, area of drywall) and optionally link to cost databases. Accuracy depends on classification and property completeness in the source model.
Facility management tools: Designed for building operators, these tools link BIM data to maintenance schedules, work orders, space management, and energy monitoring.
Mobile viewers: Simplified apps for tablets and phones that allow site workers to view models, add issues (photos, notes), and update status.
Reality capture tools: Process laser scan point clouds and photogrammetry data into usable models. Some tools automate the conversion of point clouds to BIM objects (a process still requiring human verification).
Interoperability tools: Convert between file formats (e.g., Revit to ArchiCAD), validate IFC exports, or fix geometry errors in translations.
Scripting and automation tools: Extend software functionality through custom scripts (e.g., Python or Dynamo), automate repetitive tasks (adding properties to hundreds of objects), or create custom analysis routines.
