  5. 5. BIM Overview Process and “mindset” is first and foremost 3D object-based, parametric model is the best known aspect of BIM Parametric technology allows objects to relate to each other The objects within a 3D model have “attributes” or “properties” embedded within them © 2012 Autodesk
  6. 6. BIM is Not.……… Single building model or a single database A replacement for people Perfect Revit (or any other software application) 3D Have to be 3D Complete A “pushbutton” solution © 2012 Autodesk
  7. 7. Big BIM Data vs. Little BIM Data•BIM Tools Such as Revit can: Really Big BIM • Accelerate response time to potential project issues Big BIM • Automate and Streamline tedious information gathering and decision- Research, Historical Data & Human making process Experiential Knowledge • Focus on optimal solution • Identify and remove building system Processes redundancy • Establish building performance Tools (Little BIM) metrics resulting in lower initial costs • Revit 3D and long-term operational costs Modeling © 2012 Autodesk
  8. 8. The Power of Revit Depends on How Well it isUsed Links project activities with the client’s business goals Allows project team to interface with the business of the client resulting in a greater understanding of their culture, values, and organizational business drivers Defines what is unclear and provides a roadmap through uncharted territory Provides a higher level of client service that emphasizes value to the client much sooner and with a higher level of detail than 2D CAD tools © 2012 Autodesk
  9. 9. BIM Knowledge Acquisition Progression WISDOM KNOWLEDGE INFORMATION DATA © 2012 Autodesk
  10. 10. Database Basics-To Fully Understand BIM it Helpsto Understand Database Design Fundamentals Database=“collection of interrelated data items that are managed as a single unit.” Single File vs. Multiple Files File=Collection of related records stored in a single unit Database Object=named data structure that is stored in a database. Types of objects can vary. User data views=allows different users of the database to use customized presentations of the same data © 2012 Autodesk
  11. 11. Need for Revit Rapid Data Extraction•What do we have?•Avoid GIGO!•Data abstraction: • Data is stored once • Multiple users • Multiple distinct views of tabular data•Data quality/quantity depends onproject delivery being used•Find Revit’s “hidden” data•Speed of Business • Quick resolution of problems • Discovery of new opportunities•Downstream activities depend onquality of the Revit file © 2012 Autodesk

  19. 19. Model Progression Specification and Level ofDetail Gets Everyone on the Same Page LOD 100: Conceptual LOD 200: Approximate Geometry LOD 300: Precise Geometry LOD 400: Fabrication LOD 500: As-builtModeled elements will need to be at leastLOD 300 if used for construction © 2012 Autodesk
  20. 20. Levels of Detail LOD 100 Model Elements indicative of area, height, volume, location, and orientation may be modeled in three dimensions or represented by other data. (ie., a pump would be a cube) Uses  Total project duration  Phasing of major elements  Conceptual cost allowance ($/sf of floor area)  Cost assumptions on future content © 2012 Autodesk
  21. 21. Levels of Detail LOD 200 Model Elements are modeled as generalized systems or assemblies with approximate quantities, size, shape, location, and orientation. Non-geometric information may also be attached to Model Elements. (ie., a pump would be a generic pump of approximate size.) Uses  Time-scaled, ordered activities  Estimated cost based on generic elements © 2012 Autodesk
  22. 22. Levels of Detail LOD 300 Model Elements are modeled as specific assemblies accurate in terms of quantity, size, shape, location, and orientation. Non- geometric information may also be attached to Model Elements. Accurate to contract documents. (ie., a pump would be a generic pump of accurate size complete with connections and clearances for a complete system.) Uses  Time-scaled, ordered assemblies  Estimated cost based on specific assemblies (i.e., specific wall type) © 2012 Autodesk
