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

here s what we can do
Here’s what we can do
  • Think long term
  • Simplify
  • Carry a notebook
  • Implement practical solutions
  • Involve others
here are some questions to ask
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?”
what are the take home messages
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?

maintenance overview
Maintenance Overview

1. Detect 2. Prevent. 3. Remediate

performance
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
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
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.
5s housekeeping
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.
