  1. Ewan Associates Ltd New technology for optimising and prioritising capital maintenance programmes Mark Randall-Smith Water UK Asset Management Forum 13 May 2004

  2. Ewan – Relevant Capabilities In the past two years our track record has included: • Strategic investment planning - a new approach that integrates & optimises the investment drivers • Capital maintenance planning - extensive support to a number of water companies, including application of specialist tools and services • Process review - for asset rehabilitation, asset regime & capital investment programme – and identification of business improvement opportunities • Supply demand planning - best practice approaches to capacity investment & leakage management economics

  3. Investment Planning and Delivery – how should we approach it? • For AMP3: frantic activity to develop PR99 Business Plan … • …but then it ‘stopped’ (little connection between planning and implementation) • For AMP4: With PR04 submitted, aim for • Ongoing and supportable Common Framework-compliant approach to prioritise investments and spends • Delivery of AMP5 planning (PR09 Business Plan) at the ‘press of a button’

  4. Other desirable characteristics… • Delivery of ‘Best Value’ • Deliver required serviceability at least Whole Life Cost over the planning horizon • Pragmatic • Make best use of existing data and systems • Useable by Water Company staff • Cost-effectiveness of implementation • Avoid having to spend a fortune on ‘bloody consultants’!

  5. One way to approach it… • Bottom-up, all-encompassing software tools which provide both the strategic plan and maintenance programmes for every individual main • Gives reassuring comprehensive output – but is it really appropriate? • Large data overhead – expensive! • Implies unrealistic precision • Size and complexity hinders transparency, auditability • Likely to require excessive maintenance and updating • Leaves little room for on-the-ground ‘knowledge’ judgements

  6. Another way … • Break down the problem – three levels • Strategic model – Business Plan development • Intervention budgets and targets • Allocation by broad ‘Asset Groups’ • Risk Prioritisation model • Asset level (DMA) – complete company coverage • Focus on areas for improvement • Detailed tools • Identify robust site-specific solutions using innovative technology

  7. The ‘Three Level’ Philosophy

  8. Infra vs Non-infra

  9. High level infrastructure FMEA model Matrix underpins both strategic and prioritisation processes

  10. Level 2 – Risk Prioritisation • Inputs: • Supportable intervention/ investment levels across Asset Groups from Level 1 • Cause & Effect and other models consistent with Level 1 • Outputs: • Focus on assets where detailed optioneering is required • Prioritised list of assets requiring interventions

  11. IPAD Assets Models Outputs Improve-ments Level 1: Strategic Asset aggregation  high-level groups Consistent aggregation for groups Strategic Guidance – investment scale and focus Regular re-run with evolving relationships and drivers Level 2: Risk Prioritisation Re-prioritise on cost/ risk benefit Asset Characterisation at e.g. DMA level Cause & Effect, Deterioration, Risk, Impact, Cost Review prioritisation of non-committed schemes Initial prioritisation (risk only) Level 3: Detailed Corporate GIS Optimal, costed scheme identification Detailed model formulation Programme Monitor Implement Update

  12. Conclusions • Evolving regulatory system: places new pressures on Investment Planning and Delivery methods. • Water Companies need to invest in new technology - pragmatic but effective tools to plan, prioritise and deliver capital maintenance investment programmes • The IPAD approach we recommend: • Start ‘top-down’ – based on accessible asset information • Focus detailed investigation in those areas which need it • Use consistent data and models for planning at all levels • Apply appropriate technology to find the right solutions • Benefits: • Achieve technical efficiencies in delivery • Streamline future Business Plan development
