3D Laser Scanning & Accurate Modelling

Surtech provides 3D Laser Scanning and Modelling services globally to clients who require solutions for the accurate capture and documentation of their existing facilities.

Utilizing high speed/resolution 3D laser scanners, together with specialized processing software (LFM Suite, PDMS, AutoCAD, SmartPlant & MicroStation), we can measure complex facilities or structures in high detail and deliver 3D digital point or solid CAD model data sets. With a measuring rate of >500,000 points per second, our laser scanners rapidly provide a three-dimensional representation of the scanned surfaces with high density measurements taken over the visible surfaces of the target structures. The resultant data sets are often referred to as three-dimensional point clouds (PCD’s), which can be delivered to the owner/engineers utilizing their preferred design or engineering software package, such as PDMS or SmartPlant3D.

Individual laser scans taken from different positions can be consolidated to generate dimensionally accurate digital models of a complete plant, building or any solid object. Depending on the methods used and the work processes employed in the field, overall accuracy can be within 5 millimeters.

Because 3D Laser Scanning is carried out by way of non-contact geometric measurements and existing access footways and platforms are predominantly utilized, then it presents a distinct safety improvement compared to alternate methodologies such as field measuring using tape measures for compilation of as-built information.
