Early-stage optioneering had become a major bottleneck for the delivery team. To identify suitable locations for CSO tanks, they needed to consider geology and ground conditions, topography and environmental constraints, existing assets and utilities, and prior studies and survey data. Although this information existed, it was spread across different systems, files, and teams, making it difficult to form a clear and confident view of feasibility early on. As a result, project managers struggled to understand which sites were genuinely viable, specialists spent time assessing locations that would later be ruled out, and site visits were often booked before basic constraints had been properly reviewed.

The delivery team used Sensat to visualise large areas of the catchment in a single, shared view, bringing together geology and ground investigation data, topography and environmental constraints, existing assets and underground utilities, and early option shapes and layouts in one place. Instead of piecing together information from separate sources, project managers and specialists could assess multiple potential sites from their desks, compare options side by side, and quickly see how constraints affected feasibility. This shift from fragmented data to a shared, visual context allowed the team to move from broad longlists to focused shortlists with far greater speed and confidence.

For the project delivery team, Sensat was not about producing a better visual. It was about removing friction early. By speeding up optioneering, the team could keep programmes moving, reduce wasted effort, and focus resources where they would have the most impact
