3D Laser Scanning

Our high definition 3D digital capture techniques gather a large amount of field information in a very short period of time. The process works by capturing a series of high definition 3D laser scans on site that can be processed immediately for analysis.

Intertek deploys a vast fleet of high speed laser scanners, capturing up to one million points per second, to deliver individual “spheres” of data. Each individual scan is a high resolution “laser-point” depiction of all line-of-sight objects. Adequate scans are collected from multiple locations to satisfy all desired perspective views. The scans are individually referenced to the plant coordinates with the help of our industrial survey methodology and software system called DIMES (Data Integrated Management Engineering System). These as-built high definition 3D data sets produce a virtual plant / facility environment that can be integrated directly with CAD systems (AutoCAD, MicroStation, CADWorx, AutoPlant, SmartPlant 3D, PDS, PDMS) to interrogate and clash check against new Design Models.

Elevations, measurements, coordinates, pipe diameters, and high definition photos can be extracted with the click of a mouse. Engineering groups can design directly within this data to ensure the elimination of clashes and interferences. This is opposed to the conventional alternative of relying on existing drawings that are typically not up to date.

Key areas for application include:


Creation up to date as-built documentation
3D semi-automated modeling
Clash/Interference checking
Condition and damage assessment
Data exchange with many CAD platforms
2D plans
Complete 3D CAD models from point clouds
Aid in inspections
Deformation analysis and weld peaking reports
Tank/vessel volumetric information

Our 3D laser scanning service is intended to enhance the design and constructability of any revamp, retrofit, upgrade project through all stages of the process. Key benefits of this service include:
Mitigation of risk
Minimizing shutdown periods
Minimizing offshore fabrication activities
Eliminate re-work and reduce cost of retrospective engineering
Reduction of installation man-hours
Maximizing field productivity
Minimizing field hot-work
Early project completion
