Asset Lifecycle – Design and Maintenance John Hunter MAV Conference 30 May 2013
Ability to Influence Time in the assets life cycle Ability to influence Concept / Preliminary Design Maintenance Design / Specification Procurement / Construction Commissioning and handover OperationsRenewal
Design for… Maintainability Reliability Durability Quality Deconstruction Safety Waste prevention Positive social and environmental impact
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
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
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
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.
Design for Deconstruction An opportunity to salvage / reuse components. Advantages - Ease of disassembly. Examples: Fixing mechs, welding / bolting / adhesives Potential for future reuse / recycling Prefabricn rather than permanent structures USA – C&D represents ~ 25% landfill waste
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
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
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.
Design Collaboration Design Procurement Construction Operations Maintenances Service Users
Heres what we can do Think long term Simplify Carry a notebook Implement practical solutions Involve others
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? Whats possible?
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?
Steve Jobs mantra Design is not about how things look. Design is about how things work. The big difference - outcomes.
Maintenance is end of pipe Time in the assets life cycle Ability to influence Concept / Preliminary Design Maintenance Design / Specification Procurement / Construction Commissioning and handover OperationsRenewal
Maintenance If all you have is a hammer, every problem looks like a nail.
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
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.
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.
Lean Seven wastes Overproduction Waiting Transport Motion Over-processing Spare parts Defects
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.
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
