Solution Golder developed a Geo-Engineering Content Management System (GECMS) – a Web application that leverages Esri's ArcGIS technology to manage geo- engineering documentation and spatial data. They integrated Microsoft's SharePoint with Esri's ArcGIS Server to create a single portal that could be easily accessed by all project stakeholders. Once a user is logged in to the portal, they are presented with a map of the project area and can refer to spatial search tools to locate data. For example, the user can select a subway station from the station layer and use the 'Document Search' feature to uncover all documents belonging to that particular station. The version control feature lets users maintain a record history, to ensure that they are always accessing the most up-to-date information. Finally, the instrumentation component lets users connect with instrumentation systems that are installed prior to construction so that they can monitor fluctuating conditions such as deformation, vibration and groundwater levels during the construction phase. As an added feature, the instrumentation component will be connected to the Tunnel Boring Machine (TBM) so that users can keep up-to-date on the progress of the tunnel construction while closely monitoring geotechnical instrument results. Benefits GECMS has enabled station engineers to upload their designs to a central portal for use by other engineers, TTC managers, construction firms and politicians at both the municipal and federal level. This has greatly improved collaboration and opened up the lines of communication between key stakeholders. It has also promoted a quicker and more effective design execution through easy access to critical information. Version control has ensured that all referenced spatial data is up to date and accurate, helping to minimize risk during this complex, large-scale project. Looking forward, Golder will work with Esri Canada to incorporate further visualization information into the application, helping to ensure a safe and successful subway extension. Future ideas include building 'fly throughs' – video footage of subway tunnels that will enable engineers to virtually 'fly down' a subway tunnel to view impediments and test alignment or inform the public of project progress.

" This is a fast track project and we are bound by a very tight schedule. By developing a single portal where stakeholders can access timely information and status updates, we have been able to reduce risk to get things done on time."
