- Walkway surface and stair geometry analysis.
- Premises liability and path of travel studies.
Structural Damage Resulting from Fire
Comprehensive structural evaluations of residential and commercial properties following fire incidents and subsequent fire suppression activities.
- Thermal degradation and framing distress analysis.
- Roof member, wall, and crawlspace assessments.
- Repair scope and structural remediation estimates.
Mudslides & Slope Stability
Rigorous cause-and-origin determinations for mudflows, debris flows, slope failures, and burn-scar erosion impacting property improvements.
