Chapter 2: Concentrating on scanning rails
Concentrating on scanning rails
Through a collaborative partnership, Prisma Van Steenis was the first 3D specialist in the Netherlands that produced a 3D scan with the Pegasus:Backpack at the rail tracks of Pernis Rotterdam, Netherlands. Leica Geosystems was approached by Prisma Van Steenis in November 2015 to help with this challenging project. The project came about as it was commissioned by the government for a rail contractor to firstly verify the principles of procurement and then to assess what materials, such as ballasts, sleepers and rails, were present. Prisma Van Steenis were commissioned to carry out the rail project.
The project scope entailed the scanning of the position and height of the rail tracks because the contractor was looking to renew his contract and was keen to impose the new alignment of the railway track. Before any measurements could be taken, there was an initial analysis of the project interfaces and overlaps, and the risks carried out with the scan data and the 360-degree shots. The area that was scanned was a yard with numerous tracks and switches, containing 1.5 kilometres of industrial freight, which was in full use by several carriers and companies. The complete 3D scan will be used for reverse engineering, to help with lay-plans, ballast volumes and profiles. The captured 3D data can be used to build a reliable design of a new railway track layout, delivered as a 3D model, and can also be used for BIM and quantity determination.
