Measurement and production of architectural floor plans, elevation and sectional drawings of existing buildings and structures. 3D scanning is the standard method of measurement. It captures a highly accurate data set which is reflected in the end user drawings.
A laser line is emitted repeatedly up to a million times per second as the scanner rotates in both axis. This records the 3-dimensional position of the surfaces within its sight.
Chains of scans are linked / registered together and geolocated using external targets measured with a Total Station.
The registered point cloud can be coloured with panoramic photography taken from the scans positions and matching the image pixels to the survey points.
The point cloud is imported into Autodesk Revit with FARO As-built as reference data to build a digital 3D model. A Building Information Model, BIM.
From the model 2-dimensional drawings are exported to Autodesk Autocad.
Complex footprints are accurately plotted.
Sections can be generated throughout the model.
