Condition audits can range from routine inspections through to detailed engineering inspections. AIE tailors its condition audits to suit the client’s needs, whether it be an initial inspection to identify high risk assets or a turnkey solution offering recommendations and management of the repairs. The typical process follows the path as shown in the figure below:

AIE typically categorises its condition audits into 3 areas:
Level 1 – Routine Maintenance Inspections: Checks for general serviceability and ensures no inherent safety issues. Inspections are visual only and defects/issues are documented with supportive photographic evidence. Recommendations are given for regular monitoring, repair and/or requires Level 2 condition audit.
Level 2 – Condition Inspection (representative portion or full extent): Each element of the structure is assessed along with the structure as a whole. Non Destructive Examination (NDE) is conducted and the extent of damage/deterioration is recorded. Nature and cause of the damage/deterioration, rate of deterioration and life expectancy are determined. While recommendations for repair, monitoring and/or progression to Level 3 detailed structural engineering testing and analysis are reported. Results, recommendations and conclusions are formalised by completing a detailed condition report and supportive drawings showing extent of damage and results of the audit. The aim of the condition audit is to detail to the client the current risk profile, what is required to reinstate it back to original capacity and to implement measures to minimise maintenance and prolong life.
Level 3 – Detailed Structural Engineering Testing & Analysis: Typically, only completed when identified during a Level 2 condition audit or if severe damage has been sustained which is threatening the integrity of the structure. The structure is assessed by conducting physical testing and/or structural analysis to assess current structural condition, behaviour and capacity. The aim of the detailed structural engineering inspection is to provide quantitative results for selecting the appropriate action to take as a result of the existing assessed capacity, condition and behaviour.
Depending on the material, site conditions and type of structure, different inspection and testing methods (make this a link) are implemented. The methods selected are used to identify the extent and root cause of damage, allowing for the correct remediation strategy to be selected. Specialist equipment also enables records to be logged for post analysis and reporting.
