This document discusses how 3D scanning technology can be leveraged in building information modeling (BIM) to capture existing building conditions and design context. It notes that over 47% of architecture projects now involve renovations or additions requiring documentation of existing structures. 3D scanning allows accurate capture of existing structures in point clouds or meshes that can be imported into BIM software to create as-built models, validate construction, and enable design within the captured real-world context. The document provides examples of scanning workflows and software for aligning multiple scans, registering targets, and importing scan data into BIM and facilities management programs.

BIM Leveraging 3D Scanned Data
in a Building Information Model

needed today.
Todays Data is Different
Have you changed your process?
Leverage additional intelligent
information.
Are you leveraging the power
of 3D in your documentation?
Your process should leverage the
intelligence available with 3D

Today’s Uses of scans…
 Capture existing conditions….once!
 Create accurate BIM models.
 Capture historical design.
 Design in context of reality.
 Validate construction.
 Provide accurate models for FM

Design in context…
Design with CAD typically begins with a
blank slate.
There is a context in which EVERY design
will reside…
Reality capture gives you the ability to
design in context.

13. Multiple Position Scanning
• Key - take 8 high quality
scans and create 1 file…..
• How do you align?

14. Scanning with targets
What are targets?
Targets are used to register multiple
scans, each on their own coordinate
system, onto a single, aligned coordinate
system.
• For registration each scan requires a minimum of 3
visible references
Positioning the References
• References are normally:
• Spheres
• Checkerboards paper targets
• Objects in the scan environment
