The challenge

CMDP, an alliance delivering capital works for Southern Water, oversees 150 active projects and supports 90 users across the wider AMP7 investment programme. As part of Southern Water’s broader portfolio of 2,700+ projects and 250 users, reporting was becoming increasingly time-consuming and inconsistent.

Legacy processes relied heavily on manual updates, spreadsheets, and siloed systems. Project data sat across multiple tools, making it difficult to get a joined-up view of performance, risk, or progress. With projects moving fast and reporting demands rising, CMDP needed a better way to keep stakeholders aligned and decision-ready.

The solution

Otoni’s Programme Intelligence platform was deployed to bring clarity, structure and speed to CMDP’s reporting. The platform integrates directly with Primavera P6, enabling schedule updates and programme overviews to be refreshed three times a day.

Key features included:

  • Automated tranche narrative reports and dashboards
  • Weekly reports sent to programme managers, delivery leads and construction teams
  • Standardised cost input and automated cost reporting
  • Live procurement schedules and risk mitigation tracking
  • Pre-scheduled governance gates and joint acceptance documents
  • Risk management tool providing a centralised system shared with Southern Water
  • Training delivered to empower in-house teams to build and interrogate reports
  • Single source of truth integrating data from P6, Commercial, SHE, Commissioning, Risk and CEMAR

The CMDP model has since laid the groundwork for a scalable solution that can be rolled out to other alliances and organisations.

Results and impact

By streamlining and automating the core of its programme reporting, CMDP has achieved:

  • 95% replacement of manual reporting tasks
  • 50% reduction in project delays through earlier intervention
  • 20 days per month saved for Planners and Quantity Surveyors
  • Significant reduction in required staffing levels
  • Faster, more consistent reporting that enables productive analysis — not just data gathering
  • Better forecasting, clearer governance, and higher confidence in the data
