3D Laser Scanning

Laser Scanning - Benefits

Laser scanning in the construction industry provides a quick and versatile method of capturing data in real time. In comparison to traditional survey tecniques the use of a 3D laser scanner can reduce time on site, particularly beneficial where conditions are hazardous , or for instance where a road closure in necessary.

The 3D data captured when using the scanner gives increased visibility and understanding of the site. Often helpful when designers need a another 'look' at site without leaving the office.

Designers can use the information to provide schemes that fit real site conditions, and have confidence that issues at the construction stage are minimised due to the high accuracy of the survey data.

Site Survey

ForeSite Limited carries out scanned surveys using a Leica P20 and/or a Leica RTC 360 scanner. This has a range of over 100m with millimeter accuracy, recording approximately 1 million points per second. A single scan can take just minutes and record a large volume of information. Both internal and external surveys can be conducted using either scanner. Surveys can be geo-referenced to Guernsey Grid or a local coordinate system.

Colourised Scan Data

Full Colour scans can be captured to facilitate efficient processing of the point cloud into CAD models. Alternatively these coloured point clouds can be used as a documentation of historic or otherwise important architectural features and topography. Foresite has the capability to use both laser scan and drone based data capture in order to produce models with exceptional coverage and accuracy.

Scan Data

Processing of the scan data is done in office using specialised software in order to create a point cloud. The data can be used for a wide variety of applications, 2D plans, elevational work, volumetric calculations and 3D modelling to name just a few.
