Building a Spatial Data Infrastructure for Crossrail

Summary

Geospatial data has been a key building block in all phases of the Crossrail project and as such the quality, accuracy and range of data sources has been paramount to ensuring that planning, design and construction is delivered on time and on budget. This paper will explain the methods by which geospatial data has been captured, stored and managed through a Central Enterprise Repository, eliminating duplication and loss of data through the project phases and providing a greater level of detail across the work programme than in any previous project. The paper will also show how geospatial has provided a backbone for the BIM principles that the Technical Information team follow, enabling re-use and enhancement of information without any knowledge loss as the project has progressed. This case study is relevant to any major infrastructure organisation or project developing a Geospatial or BIM Strategy.
