Terrestrial laser scanners (TLS) offer the ability to collect highly accurate high density 3D point clouds. This dissertation looks into errors evident in TLS scans, such
as edge effects, ranging errors, noise, and effect of surface reflectivity with the project scanner (which is a Trimble TX5). It then goes on to analyse the magnitude of these errors and ultimately concludes that the TLS is a suitable tool for use in Building Information Modelling (BIM)
It then analyses the suitability of the Revit add-on called Scan To Bim for use in creating Revit elements from TLS point clouds, and concludes that care needs to be taken, and identifies more research is required to determine accurate methods. It also highlights the difficulties inherent in creating complex building elements such as columns, windows, doors, and ducting which are many and varied
