Allan Howard, Technical Director Lighting & Energy Solutions at WSP, Asset Management for Smart Cities paper, June 2019

  1. 1. Asset Management for Smart Cities Well-Managed Highway Infrastructure A Code of Practice Allan Howard, BEng(Hons) CEng FILP FSLL Director Lighting & Energy Solutions Ack. Andy Warrington, Atkins
  2. 2. At a glance 2 So Smart Cities …… — Todays reoccurring message — Columns are minor structures — Their requirements are changing — Future column design will change — Asset management is now the core consideration — How to consider the existing asset?
  3. 3. At a glance 3 What is driving this? — The ‘new’ Code of Practice — A review and consolidation of current codes —Highways —Structures —Lighting — To reflect current good practice — Common issues — Consistent style and feel across all codes — Approved by UKRLG (UK Roads Liaison Group)
  4. 4. At a glance 4 Awareness — Published 28th October 2016 — Amended March 2017 — Available via UKRLG web site — www.ukroadsliaisongroup.org — Free — Electronic version only — Two year transition period — Came into force October 2018 — Forward awareness very low
  5. 5. At a glance 5 The approach — Risk & asset management based — Reactive — Time based — Condition based — Risk based — Old Codes — 222 recommendations — Not risk based — New / current Code — 36 recommendations
  6. 6. At a glance 6 What it brings — Challenges — Evidence of process — Evidence of why this process is considered suitable? — Skills and competencies — Opportunities — Tailored to local requirements — Strengthen asset management — Enables efficiencies — Supports service delivery business cases
  7. 7. At a glance 7 Standards — To deliver a safe and well maintained highway network — Good evidence and sound engineering judgement — Applying the principle of risk-based management — Implemented in accordance with local needs, priorities and affordability — Code does not outline any minimum or default standards — Includes for case studies and illustrated good practice — Provides some guidance for authorities to consider
  8. 8. At a glance 8 Risk / asset management based — Understanding the asset — If you don’t know what you have you can’t manage it — What is needed — Evidence of process — Skills and competencies — Tailored service to suit local needs / requirements — Business case for service delivery WSP inspections
  9. 9. At a glance 9 — 4 parts — Overarching principles — Highways — Structures — Lighting — 36 recommendations — Strategy and planning — Life cycle delivery — Organisation and people — Asset management decision making — Asset information — Risk and review New CoP
  10. 10. At a glance 10 Part 1: Overarching principles — Introduction — Policy Framework — Legal framework — Strategy & hierarchy — Risk based approach — Network resilience
  11. 11. At a glance 11 Part 1: Overarching principles — Performance management — Financial management — Sustainability — Procurement — The three codes — Appendices — Total of 36 recommendations
  12. 12. At a glance 12 Parts 2, 3 & 4: Asset specific — Introduction — Legal framework — Asset management information — Asset condition and investigatory levels — Inspection, assessment and recording — Programming and priorities WSP / Roch NDT testing – National Grid
  13. 13. At a glance 13 Network resilience — The ability of the community, service, area or infrastructure to detect, prevent and if required to withstand, handle and recover from disruptive challenges. — Understand — Physical resilience — Management options — Prioritisation
  14. 14. At a glance 14 New CoP recommendations
  15. 15. At a glance 15 — Applicable recommendations — Performance management —18 Management systems and claims —26 Performance management framework —27 Performance monitoring — Communications —4 Engaging and communicating with stakeholders —24 Communications Corporate
  16. 16. At a glance 16 Lighting Applicable recommendations 5 Consistency with other authorities 7 Risk based approach 9 Network inventory 10 Asset data management 11 Asset management systems 13 Whole life / designing for maintenance 14 Risk management 16 Inspections 36 Minimising clutter Risk and resilience 7 Risk based approach 8 Information management 14 Risk management 18 Management systems and claims 20 Resilient network 21 Climate change adaptation 23 Civil emergencies and severe weather emergencies plans 25 Learning from events
  17. 17. At a glance 17 Key themes — How do you deliver this service and is the process being followed? — How are you performing? — How have all the associated risks been considered? — How has the wider risk and resilience been considered? — Where is the evidence to support why this approach is right for Westminster?
  18. 18. 18 − Need to understand your asset − These are not just columns − They are minor structures !! Application to lighting At a glance
  19. 19. 19 − Launched at ILP Summit June 2019 − GN22 Asset-management Toolkit: Minor Structures − www.theilp.org.uk/atoms − Replaces TR22 (now withdrawn) ILP Guidance Note GN22 ATOMS At a glance
  20. 20. At a glance 20 Understanding the condition — Column degradation model — Understanding the asset — Condition — Residual life — Evidence — Lighting condition index — Structural support — Performance of lighting vs Westminster Standard — Energy efficiency (BS EN 13201-5) — Lighting value management process — Prioritisation system — Structural condition — Lighting performance — Road hierarchy — Crime — Local needs — Ranked list — Priced to aid funding
  21. 21. 21 − CCI • A condition index to determine the overall condition of the lighting stock and track deterioration • Use as a means for monitoring whether adequate steps are being taken to manage the stock in line with the desired strategy • Structural elements (shaft, bracket, base plate …) − Adopted by UK Lighting Board as a future indicator Column Condition Index (CCI)
  22. 22. 22 – Column Condition Index split into: • CCIave – determines the stock average presenting an overall stock condition • CCIcrit – determines the stock critical elements focussing on structurally important elements • CCIave and CCIcrit access the same visual inspection data but compute differently Column Condition Index (CCI)
  23. 23. 23 − Severity codes − 1 to 5 − Extent codes − A to E Assessment codes
  24. 24. 24 − Conversion of existing TR22 data − Collection of new data − Visual − Test house How it works
  25. 25. At a glance 25 Future expectations — Developing role — Luminaires, signs etc. — Banners, festive decorations ….. — Smart technologies — 5G — CCTV — Communication hubs to sensors — Sensors …….
  26. 26. 26 – New columns, PD6547 – Existing columns – Do you hold the design criterial? – Using GN22 to consider load capacity Load capacity Assumed residual life Age (Years) Applied Moments ColumnMomentresistance Current age Corrosion initiation period Column is corroding
  27. 27. 27 − For alighting column to be kept in service the risk associated with it should be within the acceptable range − NDT testing − Material strength − Column corrosion model Assumed Residual Life (ARL)
  28. 28. 28 Assumed Residual Life (ARL) 1. for a given environment 2. and a given column height 5. We can estimate the ‘assumed residual life’ 3. and a given column diameter 4. and a given actual measured base wall thickness
  29. 29. 29 – Determine stock condition for financial planning – Identify problem columns and trends – Develop intervention strategies based on agreed Service Levels (Life Cycle Planning) Uses of the data
  30. 30. 30 — The location of the holes needs to be controlled, for example: — Multiple holes should not be provided within the same horizontal section and should instead be spaced vertically up and down from the designated height. — The holes should be spaced one or two diameters apart vertically (again I can confirm) to ensure there is no interaction of the stress paths around the holes. — The holes shouldn’t be within 1.5m of the shoulder of the shaft. — Particular care needs to be taken for holes in the base where they are at the same level as an unreinforced door opening as sections subject to torsion will be affected by the additional hole which should be placed to the rear face opposite the door. — The height of the holes relative to the equipment should be positioned to ensure suitable drip loops are provided in the equipment cables to minimise water ingress problems through the glands. Considerations when drilling into a column
  31. 31. 31 2017 NDT test houses report an average of 3.5% are red/critical columns They report a growing number of amber assessed columns (2010-11% to 2016-37%) 10% of amber columns have turned red over 3 years PFI’s have been replacing cc 80% of their authorities stock over a five year investment period Understanding your asset has never been so important Final thought …….
