Advantages / Customer Benefits
Typical Application / Projects Snapshots 3D Laser Scanning, What is it?
A 3D laser scanner is an advanced type of survey / measurement device that is used to remotely measure surface geometry of any object with extraordinary completeness, accuracy and speed.
Unlike traditional surveying tools that are used to record certain, selected points, a 3D laser scanner automatically cover the area with thousands or even millions of closely spaced point measurements as points cloud.
Laser Scanning Workflow:
Application Areas:
Art and Architecture
Civil Engineering
Dam Design & Construction
General Surveying Industrial Forensic
Investigation of Accidents
Shipbuilding /Repair
Onshore /Offshore industries
And more…
Generic uses of Laser Scanning:
As-built 2D/3D documentation, drawings of existing structures and installations
Surveying, QA & QC
Reverse engineering
3D modeling and Simulation
Deformation/Deviation Evaluation of a existing structure
Temperature expansion/contraction analysis of a existing structure
Wind effect analysis of a existing structure
Inspection & comparative analysis during construction
GIS integration, implementation of virtual management centers
Virtual touring
3D Laser Scanning Advantages:
High details, huge volume of data collected, no data omissions
Very quick data collection process
Project risk reduction
Inaccessible areas collected
Reasonably quick 2D/3D modeling and analysis
Quick and accurate volumetry
Export/Conversion to universal formats (DXF, DWG, IGES, STEP, TXT,…)
Preventing design conflicts and enhancing coordination among different project phases or contractors in the same area
QA results can catch early deviation trends that can avoid potentially costly rework
Reducing change orders and schedule impacts
Creating an inventory and audit of the existing conditions
Data collection does not interfere with ongoing construction activities
Permanent record of construction process
Implementation of virtual management centers & Working Online
Customer Benefits:
Better quality and more complete QA results
QA results can catch early deviation trends that can avoid potentially costly rework
Minimum 50% labor savings for QA surveys
Data collection does not interfere with ongoing construction activities
Valuable geometry information is created
Project risk reduction
Increased safety
Faster project completion
And …

The Non-Contact 3D Laser Scanning demonstrates that:
Overall Saving in Labor of more than 75%, plus it provides much more Details than traditional surveying and is much Safer and Easier to deploy.
