From 2020, the high-frequency Elizabeth line service will run through 42km of tunnels under central London.
The project identified, recorded and provided access to information on structures affected, other obstructions along the route and potential mitigation measures.
Managing complex information
A multidisciplinary project generates large amounts of spatial and geographic information, and significant historical data exists from previous stages of the work.
The approach taken by the Arup Atkins joint venture design team, with support from the Crossrail Ltd's GIS team, is an exceptional Geographic Information Systems (GIS) success story.
The GIS specialists ensured that information was consistent and applicable to the challenges facing the project team, and that it was readily accessible to all staff.
A web-based GIS map tool was created to display up-to-date spatial information in an accessible way, and augmented with aerial photography and other data from third-party mapping and surveying providers.
Time and cost savings
Engineers on the project saved time on finding information and creating many project deliverables, and CAD technicians and other professionals benefitted from easy creation and updating of drawings.
The work resulted in significant cost savings compared to data management without GIS.
The project also involved seamless integration of CAD and other specialist software with GIS data and systems, ensuring that everyone involved in the project had access to the latest and most relevant information.
The project was awarded a ‘Best Practice and Innovation’ in the private sector category at the Association for Geographic Information awards 2010.
