London, UK

An underground construction information management system (UCIMS) was developed by itmsoil to monitor construction data from the new east-west rail link across London known as the Crossrail. The Crossrail project construction works, Europe's biggest construction project with projected costs of £15.9 billion, include underground development, comprising shafts, tunnels, and portals that extend beneath the already congested London underground. Given the urban environment in which the tunneling and other construction activities are occurring, monitoring of the construction works and the impact on adjacent underground and aboveground structures was a key activity for the project management and engineering teams. The UCIMS monitors tens of thousands of real-time geotechnical instruments and structural sensors as well as overall construction progress. In addition to performance monitoring of a host of construction activities, the UCIMS also tracks the progress and performance of Tunnel Boring Machines (TBMs). The UCIMS was designed to provide real-time access for all stakeholders to the construction and instrumentation data, and it required an intuitive, map-based user interface, showing progress and data locations relative to the surface features and other spatial information.
