condition assessment checklist tool to guide and help in the condition assessment process. Make an overall ACAA assessment of the entire asset using the asset condition model shown below in Figure 2. Table1: Condition Index and Impact Asset Condition Index Asset Condition Impact Description of Relative Condition Level Description of Required Condition Remaining Life (where supported)/ Maintenance Required New (Very Good) Performing as intended and/or operating efficiently. 1 - (Nil/Negligible) Very good condition – well above Required Condition. Some ageing or deterioration of a limited number of components. All asset elements meet Required Condition, and: some key elements significantly exceed Required Condition many elements well exceed Required Condition any minor deterioration evident has no affect on the asset’s functioning or availability is very well maintained > 15 yrs. Normal inspection/TMP work. No action required for all Asset Categories. Good Performing as intended but with minor 2 - Minor disruption Minor defects only – above required condition. Deterioration of some components. All asset elements meet Required Condition, and: many elements exceed Required Condition some physical deterioration may be present but it does not affect the asset’s function or availability is well maintained 10-15 yrs. Minor maintenance and inspections (5%). Attention within 1 – 2 years for Superior, High and Above Average Assets. Attention within 5 years for Average, Below Average & Low Asset Categories. Average (Fair) Performing as intended but with moderate 3 – Moderate Disruption Maintenance required Returning to Accepted of Service – at Required Condition. Noticeable deterioration or serious deterioration of specific components. All asset elements meet Required Condition, and: the asset’s functioning and availability are at acceptable levels some elements may be deteriorating needs maintenance 5-10yrs. Important maintenance and repair (10-20%). Increased diagnostic, testing, possible replacement needed before 5 years pending on criticality. Attention within 0 – 1 year for Superior, High and Above Average Assets Categories. Attention within 2 - 4 years for Average, Below Average & Low Assets Categories.
Poor Exhibiting major defects and/or not operating as intended. 4 – Major Disruption/ Increased Costs/ Loss of Revenue Requires – below Required Condition. Widespread serious deterioration or significant deterioration of a dominant components. Some elements do not meet Required Condition, and: condition of some key elements is below the limit of acceptability deterioration affects asset function or availability asset needs significant maintenance and may need renewal or upgrade 1-5 yrs. Significant renewal/upgrade Start planning process to replace, considering risk and consequences of failures. Immediate attention for Superior, High, Above Average & Average Assets Categories. Attention within 1 -2 years for Below Average & Low Assets Categories. Failed (Very Poor) Life expired and/or serious risk of imminent failure. 5 – Possible liability/ Illegal Condition Asset unserviceable – well below Required Condition. Extensive serious deterioration or serious deterioration of a dominant component Many asset elements do not meet Required Condition, and: condition of many key elements is below the limit of acceptability deterioration significantly affects asset function or availability in urgent of major maintenance or refurbishment 0-1yr. Over 50% of asset requires replacement. At immediately assess risk; replace based on assessment. Immediate action for all Asset Categories. Relative Condition is a direct comparison of an asset's Actual Condition with its Required Condition, expressed in a Relative Condition Level scale as in Table 1. The purpose of comparing actual and required condition is to: Examine the of fitness for purpose; Assess the extent of under or over-provision; and Set maintenance, refurbishment, replacement or disposal requirements. Where the Relative Condition Level shows a significant variation between Actual Condition and Required Condition, there is likely to be a significant impact on the operation of the asset. There may also be financial impacts. These need to be clearly identified as they are important in making decisions and setting priorities. Assets condition impacts considered with Asset Category are a major determinant of the priority and urgency of action to be taken in respect of a particular physical asset. Maintenance requirement is crossed referenced against the respective conditions in Table 1.
