GMC Surveying utilises the latest survey grade laser scanning technology to undertake projects that are complex, time restrictive and require a data rich solution.
Laser Scanning has an advantage over traditional survey techniques in some circumstances, in that it is able to locate a 360-degree view of the environment in a very short period of time. This enables the client to extract any detail that they require without revisiting the site. Utilising multiple laser scans, a replica of the whole environment to a survey grade accuracy can be created.
In the process of laser scanning, the high precision laser scanner is typically set up away from the subject area. This enables the environment to be scanned at a distance that does not require traffic control; a great solution for environments that are unsafe for a traditional surveyor to locate. Once a point cloud is created from the laser scanning survey all types of data can be extracted from it. For example, you are able to extract traditional 2D cad lines typically used in Engineering projects. You are also able to extract 3D modelled elements likes walls, pipes and roads using software like Revit that can then be included in a BIM model for example. BIM is becoming a very large part of construction management and laser scanning is the perfect tool to assist in the as-built documentation as well as the visualisation of design data.
And finally the laser scanned data can be used to visualise an environment and to create a virtual walk through of the environment. The client can then add design elements into this visualisation to assist when trying to demonstrate a design to other contractors. As a laser scanned survey is a complete snapshot of a project at a particular moment of time, this data can then be used to monitor how a project changes over time. This is particularly useful when monitoring a surface. Users can compare point clouds at different times to monitor any potential movement.
