European Rail Traffic Management System (ERTMS) is a European Union-wide system of signaling for railways that will improve safety, increase efficiency, and enhance cross-border interoperability of rail transport in Europe. The Swedish Transportation Administration had to introduce the railway signaling system on the country’s main railways. In 2019, Saitec was awarded the contract to prepare tender documents for constructing ERTMS in the Osby area. The 47-kilometer rail project involves designing 43 new buildings along the track and any necessary earthworks, requiring BIM technology to meet the requirements and standards.
Saitec & Trafikverket chose Bentley applications to produce models for both existing and newly designed elements, which were incorporated into a larger model and shared with stakeholders. OpenRail Designer helped create the alignments and profiles of existing tracks, MicroStation modeled the surrounding buildings, and OpenRoads Designer helped develop a scalable terrain model. The team created and managed about 2,500 drawings, modeled over 5,200 existing and 2,000 new objects, and filled over 82,000 attributes.
