  1. Asset Lifecycle– Design andMaintenance John Hunter MAV Conference 30 May 2013

  2. Ability to Influence Concept / Preliminary Design Design / Specification Procurement / Construction Ability to influence Commissioning and handover Operations Renewal Maintenance Time in the asset’s life cycle

  3. Design for… • Maintainability • Reliability • Durability • Quality • Deconstruction • Safety • Waste prevention • Positive social and environmental impact

  4. Design for Maintainability Designing features to allow ease of maintenance. Advantages – Low downtime, continuous LoS. Examples: • Grass cutting and steep slopes • Co-locating into single areas • Accessibility - light poles • Bio-retention devices • Standardisation

  5. Design for Reliability Designing assets to minimise downtime Advantages - Repeatable uninterrupted LoS. Examples: • Sealed roller bearings to prevent dust ingress • Traffic signals with diagnostic capabilities • Fibre optic network with redundant paths

  6. Design for Durability Failure-free / maintenance-free operating. Advantages – Long time to renewal. Examples: • Galvanise / paint / powder coat / stainless • Add asphalt additives in plant to counter UV R • Downpipes – S/S. • External cladding on Bus Depot Buildings

  7. Design for Quality Totality of features to satisfy needs of users. Advantages – Lean; negate rework and 10X rule Examples: • QA in design, materials, construction. • No defects; no rework • Fit for purpose and meets service levels.

  8. Design for Deconstruction An opportunity to salvage / reuse components. Advantages - Ease of disassembly. Examples: • Fixing mechs, welding / bolting / adhesives • Potential for future reuse / recycling • Prefabric’n rather than permanent structures • USA – C&D represents ~25% landfill waste

  9. Design for Safety Mitigate / minimise safety risks. Advantages – protect community and staff Examples: • Construction, maintenance, operation • Locate cabinets away from roads • Bike-safe storm water grates • Non-slip materials

  10. Design for Waste Prevention Minimise waste at each asset life cycle phase Advantages – Sustainability Examples: • Services share same trenches if possible • Group wet areas together - save pipe lengths • Reduce, e.g. water, electricity • Reuse, e.g. Brisbane tuff kerb stones • Recycle, e.g. asphalt

  11. Design for Positive Social, Environmental and Economic Impacts Advantages – To contribute positive impacts to social, environmental and economic wellbeing. Examples: • Sustainability – now and the future • Green star ratings • Meet a range of targets.

  12. Design Collaboration • Design • Procurement • Construction • Operations • Maintenances • Service Users

  13. Here’s what we can do • Think long term • Simplify • Carry a notebook • Implement practical solutions • Involve others

  14. Here are some questions to ask • “How can I / we make a whole-of-life difference with this design?” • “Who do I need to involve?” • “What’s possible?”

  15. What are the take home messages? • Design has the single biggest impact on the assets’ WOL costs and serviceability. • Design can impact for 10, 100 years and more. • We have the opportunity to create the future • - What can you do differently in your design?

  16. Steve Job’s mantraDesign is not about how things look.Design is about how things work.The big difference - outcomes.

  18. Asset Lifecycle - Maintenance

  19. Maintenance is “end of pipe” Concept / Preliminary Design Design / Specification Procurement / Construction Ability to influence Commissioning and handover Operations Renewal Maintenance Time in the asset’s life cycle

  20. Maintenance “If all you have is a hammer, every problem looks like a nail.”

  21. Maintenance Overview 1. Detect 2. Prevent. 3. Remediate

  22. Performance Inherent Reliability – How the asset was designed. We cannot change reliability unless by re-designing or replacing with better parts Operating environment – How it will be operated. ~ 40% of failures are due to Operator handling. Maintenance – Detect, prevent, remediate

  23. Performance Indicators Leading Indicators Forward looking (windscreen). Allows us to examine the process. Lagging Indicators Backward looking (rear-vision). Allows us to measure the output of a process.

  24. Condition ratings

  25. P-F Curve

  26. Planning and Scheduling

  27. Maintenance Contracts • Inspection – such as checking for wear and tear, breakage and reporting back. • Preventive – e.g. In a building or P&E, calibrating building plant or lubricating. • Full labour – 100% labour coverage, but no materials cover. • Full coverage – 100% coverage for labour, parts, materials and breakdowns.

  28. Lean

  29. 5S Housekeeping • Sorting – Keep only the tools essential for your job. • Setting in Order – Arranging tools to eliminate time working with them. • Shine – Keep workplaces clean, tidy and organised. • Standardising – Systemise activities where possible. • Sustaining – Maintain new standards and do not allow to lapse.

  30. Sustainability • Designing for maintainability • Design for reliability • Design for durability • Design for quality • Design for safety • Design for Deconstruction • Design for Waste prevention • Design for positive social impact
