22 BASIC TRAINING Technology: Field Technology: Office The Process

23 Multi Discipline Use Hands Off Measurements Measures Complicated Objects Reduces Field Time Basic Training: Advantages Maximizes Safety Return to the Model Non-Destructive Non-Intrusive

24 Technology-Office: Making the Point Cloud Importing Registration / Stitching Cleaning Web Publishing Translating

25 Technology-Office: Making the Point Cloud Importing Registration / Stitching Web Publishing Exporting / Translating Leica Cyclone LFM Faro Scene Recap Pro Others.. Not all Equal

26 Technology-Office: Using the point cloud Using directly as 3D Visual Background Coordinate against existing conditions w/o modeling Pre-Con: Truth model to existing conditions As-built: Update model to built conditions Converting to 3D Model Innovation gap Big dollars being invested now Direct Analysis Floor Flatness / Floor Levelness

27 Technology-Office: Using the point cloud Using directly as 3D Visual Background Revit, Navisworks & AutoCAD Leica CloudWorx Microstation, PointTools Converting to 3D Model Scan to BIM, Clear Edge, CloudWorx(Revit), LFM, Elysium Global Direct Analysis Trimble RealWorks, Hypsometric, Civil 3D

28 New Point Cloud Engine Technology-Office: AutoDesk s Help Point Clouds can be bigger Enhanced Visualization Same format for AutoCAD, Revit & Navis Toggle Point Cloud Colors It s getting easier to use scan data. Edit, cleanup and segment tools Fitting tools are still 3rd Party

29 BIM atite One of the results of a report, Advancing the Competitiveness and Efficiency of the U.S. Construction Industry, commissioned by the National Institute of Standards and Technology (NIST) from the National Research Council (NRC): Greater use of prefabrication, preassembly, modularization, and off-site fabrication techniques and processes.

30 Existing Conditions Design Construction Operations BIM is a process aiming at a result One result is a coordinated model of the building systems in their true and proper location.

31 Existing Conditions Design Construction Operations = Scanning Opportunity

32 2012 McGraw Hill Construction: SmartMarket Report

33 BIM atite: Rick Scanning Projects 57% 43% Non-BIM BIM

34 BIM atite: Projects by Revenue 14% 86% Non-BIM BIM

35 BIM atite: Buyer Demographics, Revenue 12% Owner is GC/CM 40% 48% Contractor Designer Owner

36 Level Of Development 200 vs w/ enhancements System Id Point cloud modeling vs plan modeling Realities: Modeling Expectations

37 Realities: Modeling can be $$

38 Model from Scanning May not be the same as a Design Model May not be the same as a Construction Model Realities: Model Expectations

39 Model from Scanning May not be the same as a Design Model May not be the same as a Construction Model Realities: Model Expectations

40 Realities: Model Expectations Level of Accuracy (LOA) usibd.org Level of Development (LOD) bimforum.org/lod

41 Level of Problem Accuracy (LOA) Solved usibd.org Level of Development (LOD) bimforum.org/lod Realities: Model Expectations

42 Realities: Point Clouds don t align Establish a site/campus coordinate system Distribute it Consider use of shared coordinates Leverage conventional survey control
