High definition reality capture, or as it's more commonly known, laser scanning, is the rapid and unobtrusive method of capturing a large amount of 3 dimensional measurements. Primarily used for as-builts surveys the method of survey has many other applications such as clash detection surveys, volumetric surveys, space planning, asset mapping and facilities management and virtual tours.

There are a number of tools that can utilise laser scanning. Terrestrial Laser Scanners, Drones, Handheld Scanners, LIDAR and Mobile Scanning Systems all use laser scanning to produce survey data. At Project Surveys we have a suite of Leica Terrestrial Laser Scanners to suit a wide range of site conditions. To carry out the surveyors, one of our technicians will visit the site and position the scanner at key points throughout the facility, as long as there are clear unobstructed site lines the scanners will capture everything. To capture all aspects of the job the technician may have to carry out a large number of 'scans'. The more complex the site the more scans will be required. The laser scanners fire out a pulse of lasers which record millions of individual xyz coordinates relative to the scanners position. Imagery can also be requested, which applied rgb values to each coordinate, allowing materials and finishes to be determined. 

Projects can range from just a small number of scans to thousands, depending on the size and complexity of the facility being captured.

Reality Capture


High definition reality capture was undertaken throughout the Circular Quay Precinct. This included both above and below the suspended decks.

LIDAR data and Terrestrial Laser Scanning was utilised to capture ground level detail & city wide detail to produce a large scale model.
