Key Elements of Specific Defect Analysis:
- Identification of the Defect
- A precise description of the issue (e.g., cracks in walls, damp patches, structural deformation, leaks, etc.)
- Understanding how and where the defect manifests.
- Investigation of the Cause
- Root cause analysis (e.g., poor workmanship, material failure, design flaw, settlement, water ingress, corrosion, thermal movement).
- This may involve destructive or non-destructive testing/investigations, moisture readings, structural analysis, thermal imaging, etc.
- Extent of the Damage
- Determining how far the problem has spread.
- Evaluating whether it is localised or symptomatic of a wider systemic failure.
- Assessment of Risk and Impact
- Evaluating the implications for the building’s safety, functionality, and aesthetics.
- Assessing short- and long-term consequences (e.g., safety hazards, structural instability).
- Remedial Recommendations
- Providing a detailed plan for rectifying the defect.
- May include repair options, material replacement and/or design adjustments.
- Documentation and Reporting
- A comprehensive defect analysis report is typically produced.
- May include photos, sketch drawings, test results and where requested timelines, and cost estimates.
Example:
If a client reports cracking in an external brickwork wall, a specific defect analysis would:
- Inspect the crack patterns, direction and width.
- Review the construction of the property and load paths.
- Determine whether the cracks are due to overloading, shrinkage, corrosion, or settlement or another reason.
- Recommend specific repairs (e.g., lintel replacement, underpinning, crack stitching).
Benefits of Specific Defect Analysis:
- Targeted and cost-effective repairs.
- Prevents recurrence of the issue.
- Enhances building safety and longevity.
