Building Condition Survey v Building Pathology Services: The Key Differences

The difference between a Building Condition Survey and Building Pathology lies in their purpose, scope, and depth of investigation:

1. Building Condition Survey

Purpose:

To assess and document the current physical state of a building.

Focus:

• General wear and tear

• Maintenance issues

• Structural integrity

• Compliance with regulations (e.g., safety, accessibility)

• Identification of defects (but not always the cause)

Scope:

• Typically visual inspection

• Often done as part of due diligence (e.g., property purchase, insurance, or maintenance planning)

• Descriptive and often checklist-based

Output:

• A report with condition ratings (e.g., good, fair, poor)

• Recommendations for repairs or upgrades

• Cost estimates for remedial works

  
  

Professionals Involved:

Building surveyors, engineers

2. Building Pathology

Purpose:

To diagnose the cause of building defects and failures.

Focus:

• Investigating the root causes of issues like:

  • Cracks, damp, mould

  • Structural movement

  • Material failure

  • Thermal bridging or condensation

• Understanding why the problem occurred (e.g., poor design, construction defects, material degradation)

Scope:

• Often involves testing (moisture meters, core sampling, thermal imaging, etc.)

• May include long-term monitoring

• Scientific and technical analysis

Output:

• A detailed diagnosis of the defect

• Recommendations for specific remediation

• Sometimes includes expert witness reports (e.g., for litigation)

Professionals Involved:

Building pathologists, forensic engineers, specialised consultants
