Point Clouds and BIM Workflow Guide

How to use Assemble to share Point Cloud along with BIM

Overlay as-built data on top of BIM and share it with all team members and owners – in a collaborative environment.

  1. To begin, define your use cases – common ones are listed below:
    1. Demolition
    2. Installation and Placement
    3. QA/QC
    4. Progress Tracking
  2. Next, obtain your data – there are two main ways to do this:
    1. Use your own equipment, either with tripod-based devices or handheld devices
      1. Tripods are more prevalent and are designed for bigger spaces; Scanners have 120-1000m range
      2. Handhelds are generally used for smaller rooms (e.g. mechanical room or closet) and have 10m range
    2. Hire a Scanning Service to come in and obtain your data; ensure that you have clearly specified your requirements for format, accuracy, and registration
  3. Finally, understand the opportunity to avoid converting the Point Cloud – use the intelligence of the Assemble Desktop Application to provide 3D context:
    1. Aid in recognizing shapes
    2. Tag them as objects and create point cloud component library
    3. Perform clash detection between CAD-to-CAD or Point Cloud-to-CAD
    4. Use animation tool to remove and move demolition objects
    5. Merge them with your current construction Building Information Model
