  1. UK Roads Liaison GroupCross-asset decision making Garry Sterritt Asset Investment Manager, Roads Directorate, Transport for London

  2. Where we started • Two simple questions • How much should we invest in our highway assets? • Where do we invest in to get the best outcomes?

  3. Cross-asset decision making • It was decided that all asset types should be assessed using a common approach • Why? • To support cross-asset comparison and trade-offs • To ensure all investment needs are treated fairly and objectively • To ensure finite resources are invested in the best manner • How? • One team is responsible for cross-asset investment and prioritisation

  4. Two questions – two streams of work Asset Investment Planning Asset inventory & condition data Asset Investment Model Investment options & split by asset Agreed budget, asset splits & asset strategies Asset deterioration models & cost data Investment scenarios & strategies Value Management Analysis of condition data Value ManagementModel Optimised forward works programme Risk rate & costs schemes & options Identify candidate schemes Network intelligence Asset budgets &strategies

  5. Asset Investment Planning

  6. Asset Investment Planning:Balancing Cost, Satisfaction & Risk • Strong correlation between SOGR and Customer Satisfaction • SOGR has a major impact on WLC (Capital and Revenue) • SOGR of bridges and structures has a lower impact on customer satisfaction • A low SOGR results in higher risk exposure

  7. Asset Investment Model: Outputs A range of model output reports can be selected

  8. Asset Investment Model: Outputs ? ?

  9. Asset Investment Planning:Customer Levels of Service • We asked road users, in face-to-face surveys: • To identify their preferred intervention level • To identify their minimum acceptable intervention level

  10. Levels of Service The acceptable SOGR range for structures will be engineer driven The customer LoS work will help define an acceptable range for c/w and f/w

  11. Value Management

  12. Value Management • Value Management - a systematic approach for identifying, assessing, prioritising and optimising a portfolio of projects, based on an agreed set of Value Criteria, which maximises contribution to the business objectives for a defined budget • A process for ensuring fair allocation of resources, taking account of value drivers and scheme specific information

  13. Value Management documentation • Value Management of the capital programme • Part 1. Overview • Part 2. Carriageways • Part 3. Footways • Part 4. Structures • Part 5. Tunnels • Part 6. Lighting • Part 7. Drainage • Part 8. Safety barriers • Part 9. Green estate

  14. Value Management Criteria • Safety – the risk posed to the public • Functionality – the risk to network performance; including but not restricted to, availability and reliability • Environment – the risk posed to the environment • Financial – providing WLC savings considering both direct costs to TfL and indirect costs to the economy Risk Scoring Financial Scoring

  15. Value Management: Risk Scale

  16. Where to Spend: Optimising Forward Programme Carriageway • Optimise risk for the defined budget • Each scheme has several options where risk and cost are evaluated for each Optimise Option 1 Option 1 Option 1 Option 1 Option 1 Option 1 Option 1 Option 1 Option 1 Scheme G Scheme C Scheme I Scheme A Scheme E Scheme B Scheme F Scheme D Scheme H Option 2 Option 2 Option 2 Option 2 Option 2 Option 2 Option 2 Option 2 Option 2 Option 3 Option 3 Option 3 Option 3 Option 3 Option 3 Option 3 Option 3 Option 3 Optimum Bundle Structures c/w Scheme B Option 1 c/w Scheme C Option 3 str Scheme D Option 2 str Scheme E Option 3 str Scheme F Option 1 Lighting lig Scheme H Option 2

  18. Next Steps • Asset Investment Planning • Revising carriageway and footway deterioration • Building in c/w and f/w levels of service • Building structures and lighting models • Improving user interface and output reports • Version 2 scheduled for October 2011 • Value Management • Reviewing strengths/weaknesses of 2010/11 work • Revising and refining risk scales • Updated risk scale and process by Sept 2011 • 2012/13 to 2014/15 programme to be updated post Sept

  19. Conclusions • Vital to have one part of the business responsible for cross-asset investment/prioritisation • Agree common cross-asset criteria as early as possible • Don’t expect it to be right first time • Don’t expect it to be perfect – they are decision support processes • Don’t expect it to stand still
