Condition Assessment & Survey
Structural Condition Survey, Dilapidation Reports & Remaining Capacity Evaluation

TRSC condition assessments and structural condition surveys evaluate the current state of an existing structure, quantify deterioration, and determine what intervention, if any, is warranted. Each condition survey produces a risk matrix: consequence severity (1–5) multiplied by likelihood of occurrence (1–5), following AS/NZS ISO 31000:2018. This matrix directly drives our Make Safe and Monitor hierarchy and justifies every intervention recommendation. Unlike standard construction condition surveys, TRSC assessments are quantitative: we measure, test, and calculate rather than observe and estimate.
Our methodology distinguishes between three conditions that are routinely conflated: deterioration, structural inadequacy, and imminent failure. A concrete element with visible spalling may retain full structural capacity. A masonry wall with cracking may be stable under all credible load cases. These distinctions are commercially significant, an asset owner facing a major remediation recommendation based on visual inspection alone has every reason to commission a rigorous condition assessment before committing capital.
Every condition assessment includes a written remediation hierarchy: Monitor, Make Safe, Repair, Strengthen, Replace, in order of increasing intervention and cost. We identify which elements require which level of intervention, quantify the consequence of deferral, and specify what monitoring would be required to safely extend deferral periods. This allows asset owners and fund managers to make informed, defensible decisions about capital allocation across their portfolios.
Condition assessments are typically conducted periodically, annually, or following significant weather events or reported damage. TRSC designs condition monitoring systems that extend the interval between formal assessments by providing continuous or periodic data on structural behaviour, reducing ongoing engineering costs while maintaining appropriate risk management.

Capabilities
Visual & Physical Condition Inspection
Systematic inspection using TRSC-developed protocols. Physical testing including tap testing, crack width measurement, cover depth checks, and surface hardness assessment alongside photographic documentation.
Risk Classification Matrix (AS/NZS ISO 31000:2018)
Structured risk evaluation for each inspected element. Consequence severity and likelihood of adverse outcome each rated 1–5, producing a risk matrix that directly informs intervention priority and urgency.
Deterioration Mapping & Photographic Documentation
Georeferenced mapping of defect types, extent, and severity. Photographic records indexed to inspection locations. Comparable format for repeat assessments to quantify deterioration rate over time.
Structural Capacity Evaluation
Engineering analysis of structural capacity based on observed condition. Where condition data indicates reduced capacity, quantified analysis is performed to determine residual margin against design loads.
Remediation Hierarchy Recommendation
Explicit recommendation for each defect category: Monitor, Make Safe, Repair, Strengthen, or Replace. Recommendations include cost-of-deferral analysis and monitoring requirements for extended deferral.
Lifecycle Maintenance Planning
Five- to twenty-year maintenance schedules calibrated to the structure's condition trajectory. Budget estimates for each maintenance intervention to support asset management planning.
Condition Monitoring System Design
Design of automated monitoring solutions, tiltmeters, crack gauges, strain gauges, and corrosion sensors, to provide continuous data between formal condition assessments.
RPEQ-Signed Condition Reports
All condition assessment reports are certified by a Registered Professional Engineer of Queensland. Reports are structured for use by legal, insurance, and asset management teams as well as engineering audiences.
Frequently Asked Questions
What is included in a condition assessment?
A TRSC condition assessment includes: visual and physical inspection of all accessible structural elements; photographic documentation; defect mapping; risk classification using a consequence × likelihood matrix; structural capacity evaluation where warranted; a remediation hierarchy recommendation for each defect category; and an RPEQ-signed report. The scope is adjusted to the asset type, age, and the decisions the owner needs to make.
How is the risk matrix used?
The risk matrix provides a structured, defensible basis for prioritising intervention. Each structural element or defect is assigned a consequence rating (1–5) and a likelihood rating (1–5). The product of these ratings determines the risk level, which maps directly to an intervention urgency: immediate Make Safe, planned repair within twelve months, monitor and review, or no action required. The matrix format ensures that limited capital is directed to the highest-risk elements first, and that deferral decisions are documented rather than assumed.
What happens after a condition assessment?
The condition assessment report is the starting point for decision-making, not the end. TRSC typically follows up with the asset owner to walk through findings, prioritise intervention items, and develop a scope of works for remediation design, or, where monitoring is the appropriate response, a condition monitoring system design. We can manage the full process from assessment through to RPEQ-certified remediation, or we can hand findings back to the owner's in-house team.
How does TRSC's approach differ from a standard engineering inspection?
Standard engineering inspections are typically visual-only, rely heavily on the inspector's experience and judgment, and produce qualitative recommendations. TRSC condition assessments are quantitative: we measure, test, and calculate rather than observe and estimate. The risk matrix framework means our recommendations are traceable to evidence rather than professional opinion, which matters when findings are used to justify capital expenditure or deferral to boards, insurers, or regulatory authorities.
Can a condition assessment replace a full structural investigation?
In some cases, yes. If the structural question is about condition rather than capacity, whether the structure is deteriorating and how quickly, a condition assessment may be sufficient. If the question is about whether the structure can carry a specific load, support a change of use, or meet a performance standard, a more detailed structural investigation with analysis is required. TRSC will advise on the appropriate scope during initial consultation, at no cost.
