Three-Dimensional Integrated Survey for Building Investigations

Area of Science:

• Geomatics and Surveying
• Structural Engineering
• Digital Heritage

Background:

• Building collapses necessitate accurate structural analysis and documentation.
• Traditional survey methods may lack the detail required for complex structural assessments.
• Digital modeling offers a potential solution for capturing intricate structural data.

Observation:

• An integrated survey combining topographic, photogrammetric, and terrestrial laser scanning was conducted.
• Photogrammetry captured regular structural elements, while laser scanning detailed architectural features and high-curvature areas.
• Texture processing enhanced the 3D structural representation of the collapsed building.

Findings:

• The integrated survey successfully generated a detailed three-dimensional (3D) model of the collapsed building.
• Data analysis aided in identifying the causes of the building collapse.
• The 3D model proved valuable for reconstructing the collapsed section of the structure.

Implications:

• Integrated surveying techniques are feasible and effective for post-collapse structural analysis.
• This approach significantly contributes to the preservation of architectural and historic heritage.
• Detailed 3D modeling supports disaster investigation and heritage reconstruction efforts.
