BIM for Building Sitework

764 views

Published on

  • John,
    Just looked at your slides on slide share.
    I am interested in gaining some basic knowledge in the next 48 hours. What software are you building your sub-grade utilities, roads, etc? 3D Laser Scanning has been the main path of all of my modeling experience however I have recently been requested to create a BIM of a site in MD that includes every site element but the building. We designed the civil portion of the project and have access to most of the dry utilities. Would you have an half an hour or so to discuss this topic? 301-916-4100 or jprice@vika.com in maryland.

  10. 10. Key DifferencesDesign & Technology Civil Engineering with Sitework― Real-World Coordinates― Tied by existing conditions/constraints― Design includes existing and proposed conditions, not just all new― Different authoring software than building design― Authoring software is geared more toward public works type projects― Less prefabricated elements or “system” components― Site BIM Management techniques differ

  12. 12. So, WhyDifferences of Sitework Key VDC for RBF?
  13. 13. Internal Impacts RBF? So, Why BIM for― Better documentation of existing utility conditions― Detailed surface improves fine grading and ADA design― Model Based/Dynamic Design and Plan Production = Increased Efficiency, Fewer Errors, and Better Quality End Product
  14. 14. Internal ImpactsComplete shift in QA/QC process using collaboration software ― General Visual QC/Layers ― Utility Clashes ― Utility Cover ― Utility Structure at Grade
