The first laser scanning systems were developed in the USA in the mid-1990s in response to an industrial requirement. The modelling of as-built information is particularly complex for industrial plant. The system was therefore developed for computer applications covering libraries of typical objects together with their attributes (external and internal diameters, insulation, materials; and including relevant national or international standards (such as DIN, BS, NF or ISO, etc.)).
The raw measurement data is an X, Y, Z point cloud from which we can carry out a clash analysis between the existing situation and a new design, or generate 3D models in common CAD formats.
For projects involving :
the method offers the following advantages :
Created from point clouds in conjunction with photographs, 360° panoramic visualisations give an excellent understanding of the existing site as well as a rapid measurement capability.
A virtual reconstruction of the geometry of the object, the 3D model is the preferred medium on which to base your plans.
A virtual reconstruction of the object in the form of a textured model, the 3D visualisation is your essential communication tool.
The BIM structure adds intelligence to your 3D models. Once the model is structured it becomes universally useful ! Numerous information-rich by-products can then be easily created.
By comparing a point cloud of the existing installation with your new design, we can determine the likely clashes in advance and thus reduce the eventual cost of your works.
Elevations and horizontal and vertical sections enable the viewer to access the detail of the measured object and to understand the complexities of the whole site.
The immersive walkthrough or pedestrian view is an ideal communication tool which places you at the heart of the 3D model.
Quality and accuracy of your completed structures … benefit from quality control delivered by an external and independent surveyor.
We carry out a complete survey of your storage tanks to verify their conformance to relevant standards.
This complete basic dataset emerges directly from our measurements. It is a digital archive of the measured object but at the same time it provides you with the opportunity to extract any type of plot or of 3D model.
Greater accuracy, greater flexibility … we operate at every stage of your project to set out the reference points required for construction.
The topographic map shows the existing situation on the ground, and is needed at the outset of your project.
