The CONDITION of each PIECE OF EQUIPMENT is evaluated using five criteria:

• Physical condition based on visual inspection – Almost as

reliable as predictive maintenance, especially when combined with other factors.

• Age factor – Evaluate condition based on useful life,

frequency of operation and whether rebuilt.

• O&M Protocols – Completeness of manuals, records and

SOPs

• Repair history – A refinement on Reliability.
• Current Operational Status – Out of service and not

repairable or operating with no discernible problems?

Equipment Name: Asset ID Date: Classify the equipment based on the following criteria 1 Frequently Operated Major = 1 Frequently Operated Minor = 2 Frequently Operated rebuilt/reconditioned = 3 Weighting Factor Infrequently operated = 4

• The recording should fully document the

inspection with suitable quality video and audio.

• The inspection should provide an unobstructed

view of the entire pipe and use reverse set-ups where necessary to complete the inspection.

• Pipe must be adequately cleaned to see any

structural defects or construction features.

• Care must be exercised to insure acceptable

lighting is provided, particularly in larger diameter pipe.

Codes organized into 4 Families:

• Structural Defects – 13 groups
• Operational and Maintenance Defects –

6 groups

• Construction Features – 4 groups
• Other

3/15/2013 8

Grade 5 Major Defects that should be reviewed and prioritized for repair or reassessment Grade 4 Significant Defects that will likely change

• ver time and should be monitored

Grade 3 Moderate Defects but little change in condition expected Grade 2 Minor Defects Grade 1 Excellent structural condition

• An enterprise that is serious about

sustainability will use its sustainability report to define criticality in order to arrive at Business Risk

Meeting the needs of the present without compromising the ability of future generations to meet their own needs

• Based on performance in three key

areas (Triple Bottom Line).

• Economic
• Environmental
• Social

• If an Asset Management “program”

is intended to help clients achieve sustainability, how will you know when you’ve achieved it?

• What do you measure and report
• n to show you are sustainable?

3/15/2013 12

• 1. Executive Summary – Statement on the

significance of sustainability to the organization

• 2. Organizational profile – How is the utility
• rganized? Who are the directors and managers?
• 3. Facility Profile – Describe the process and a site
• plan. Include an aerial photo if one is available.

Consider performing a Vulnerability Assessment or updating an existing one.

• 4. Environmental Considerations

a) Emissions and Waste b) Resource Use c) Resource Recovery and Production d) Sustainable Materials and Material Use e) Facility Footprint

• 5. Economic Considerations

a) General b) Cash flow c) Balance Sheet

• 6. Social Considerations

a) Workforce b) Special Stakeholder Considerations

3/15/2013 14

• 7. Technical Considerations

a) Reliability and Redundancy b) Collection System Integrity c) Future Expandability and Optimization d) Resiliency and Adaptability

• 8. Future Recommendations

• The sustainability plan defines your mission
• What are your environmental priorities?
• What are the expectations of your customers?
• How will you pay for it?
• Once you know your mission then the criticality of

each asset can be evaluated on a scale of 1 (low importance) to 5 (mission critical)

ASSET RANKING

• The Business Risk Score for any given

asset is derived by multiplying the condition score by the criticality score.

• Results in a score between 1 and 25
