2. Detailed Structural Evaluation

Following the initial screening, detailed assessments are performed on selected structures to determine the extent of damage more precisely.

Involves structural analysis and engineering tests.
Assesses load-bearing capacity, foundation stability, and material degradation.
Results guide whether a building can be repaired or must be demolished.

3. Data Collection and Documentation

Accurate data collection is the backbone of damage assessment.

Use of digital tools such as GIS (Geographic Information Systems) and mobile apps.
Photographs, sketches, and detailed reports.
Recording GPS coordinates for precise mapping.

4. Damage Categorization and Reporting

Structures are classified based on damage severity:

Minor Damage: Small cracks, cosmetic issues.
Moderate Damage: Structural cracks, minor stability concerns.
Severe Damage: Major structural failure, unsafe for occupancy.
Collapse: Total destruction.

These categories inform response priorities and rebuilding strategies.
