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
Technology-Office: Making the Point Cloud Importing Registration / Stitching Cleaning Web Publishing Translating
Technology-Office: Making the Point Cloud Importing Registration / Stitching Web Publishing Exporting / Translating Leica Cyclone LFM Faro Scene Recap Pro Others.. Not all Equal
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
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
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
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.
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.
Existing Conditions Design Construction Operations = Scanning Opportunity
