LIDAR scanning and BIM digital model
3D laser point-cloud scanning, commonly called LIDAR, is an extremely precise tool for surveying a building and creating its digital twin for BIM, or accurate CAD plans of complex buildings.
Technique
What are LIDAR and BIM models?
LIDAR stands for “Laser Imaging Detection And Ranging”. Imagine a laser rangefinder sweeping 360° about a million times per second: the result is a point cloud accurate to a few millimetres at 50 m.
Combining the scan positions digitally recreates the building in three dimensions as its digital twin: the BIM model (Building Information Modelling).
The model is then enriched with data on the building’s equipment (maintenance cycles, prices, quantities, dimensions…) such as heating, air conditioning, ventilation and plumbing.
On-site scanning
Our operators place spheres so the scanner can align the point clouds precisely, scanning from several positions to capture the building’s geometry.
Point cloud and 3D modelling
The scans are combined and cleaned into a point cloud of the whole building, from which a 3D model and plans are exported.
IFC model
The IFC model is the exchange standard for BIM design; its data can be used to simulate HVAC flows or manage maintenance (CMMS).
Why carry out a 3D survey of your building?
Producing plans of your building
Alteration or energy works require a permit or prior declaration; our clients ask us for the drawings, areas and volumes of the existing building.
Planning your works precisely
Crane positioning, facade renovation, photovoltaic projects or inspections: point clouds offer endless possibilities for 21st-century construction.
Managing the building and its equipment
With the right tools, BIM helps manage costs and maintenance intervals, with a digital history of interventions throughout the building’s life.
Our expertise
We produce surveys and digital models with controlled lead times and costs, alongside or independently of our airtightness tests.
