UMC Asset Management 2 — Questions and Answers
Question 1: Which metric best quantifies the remaining useful life of a utility infrastructure asset?
- Net book value divided by annual depreciation
- Condition score minus criticality rating
- Age divided by design life expressed as a percentage remaining (Correct answer)
- Replacement cost minus accumulated depreciation
Correct answer: Age divided by design life expressed as a percentage remaining
Remaining useful life is most directly expressed as the proportion of design life not yet consumed, calculated by subtracting the ratio of current age to design life from 100%.
Question 2: In a Levels of Service (LOS) framework, which category directly reflects customer-facing performance expectations?
- Operational LOS
- Community LOS (Correct answer)
- Technical LOS
- Financial LOS
Correct answer: Community LOS
Community LOS captures what customers and stakeholders expect from a utility, such as water quality, reliability, and responsiveness.
Question 3: A utility uses a risk matrix to prioritize rehabilitation projects. Risk is defined as:
- Consequence of failure only
- Probability of failure only
- Probability of failure multiplied by consequence of failure (Correct answer)
- Asset age multiplied by replacement cost
Correct answer: Probability of failure multiplied by consequence of failure
Risk in asset management is the product of the likelihood that an asset will fail and the severity of the impacts if it does.
Question 4: Which document type serves as the primary long-range financial planning tool for capital asset renewal in utility asset management?
- Operations and Maintenance Manual
- Capital Improvement Plan (CIP) (Correct answer)
- Annual Operating Budget
- Asset Inventory Register
Correct answer: Capital Improvement Plan (CIP)
The Capital Improvement Plan identifies and schedules major capital projects, including asset renewals, over a multi-year horizon.
Question 5: What is the primary purpose of establishing a criticality rating for utility assets?
- To determine depreciation schedules for accounting purposes
- To prioritize inspection and maintenance resources based on failure consequences (Correct answer)
- To calculate the replacement cost of aging infrastructure
- To comply with EPA reporting requirements
Correct answer: To prioritize inspection and maintenance resources based on failure consequences
Criticality ratings help utilities focus limited inspection and maintenance resources on assets whose failure would cause the greatest harm.
Question 6: Which approach to asset valuation reflects the current cost to replace an asset with one of equivalent service capacity?
- Historical cost
- Net book value
- Current replacement cost (Correct answer)
- Salvage value
Correct answer: Current replacement cost
Current replacement cost estimates what it would cost today to replace the asset with a functionally equivalent alternative, regardless of what was originally paid.
Question 7: Under the AWWA asset management framework, which of the following best describes a 'reactive' maintenance strategy?
- Scheduling maintenance based on manufacturer intervals
- Replacing assets before they reach end of life to avoid failure
- Repairing assets only after they have already failed (Correct answer)
- Using sensor data to predict failures before they occur
Correct answer: Repairing assets only after they have already failed
Reactive (or corrective) maintenance means restoring an asset to service after it has failed, rather than preventing the failure in advance.
