"""
Vibration damage assessment for injurious affection

Calculates damages from construction vibration including:
- PPV (Peak Particle Velocity) threshold analysis
- Cosmetic vs. structural damage classification
- Repair cost estimates

Based on vibration damage criteria and construction monitoring standards.
