BIM4I – Laser Scanning a Railway Corridor
BIM4I – Laser Scanning a Railway Corridor Summary:
The Scan2BIM team at Severn Partnership were commissioned to laser scan and 3D model 500 metres of railway corridor and four listed bridges.
Between 2014 and 2016, Network Rail commissioned the Bath Corridor Civils Works (Great Western Electrification programme). to install 25KV Overhead Line Electrification (OLE) equipment on the Great Western Mainline. A critical and complex part of the route passes through the Bath World Heritage Site. The works at Bath included; raising parapet heights to line side retaining walls, landscaping, works to two listed bridges, OLE bespoke foundations/masts as well as works to the main station.
As the corridor is situated in a World Heritage site and has various Listed structures, Severn Partnership were commissioned to laser scan a 500m stretch of railway which included four listed bridges to facilitate design and listed building consent.
The scan data was collected over two night-possessions with a Leica P20.
Once the scan data was processed, using Autodesk Revit our modelling team produced a 3D model to LOD4, including all historical features. The model comprised of the four listed structures as well as 500 metres of retaining walls, topography and tracks.
