This project lays the foundation for building and exchange hub for locational and security data and risk assessment of potential excavation work.  It acts primarily at 2 stages: upstream of the mark-out process, as a decision support tool to help streamline, improve and guide the mark-out process, and downstream of the mark-out to gain and preserve information gained from such field verified data, and added intelligence to each utility asset management system related to the potential proximity of other utilities, and possible criticality of proposed construction activity in a given site that puts at risk key assets.
