Demolition in railway environments requires precise planning and execution due to operational constraints and complex interfaces. Production rates vary significantly based on structure type, access, and demolition methodology. Modern techniques including robotic demolition and controlled collapse have improved efficiency while maintaining safety standards.

Key Statistics:

• Average production: 150-200m³/day
• Concrete processing: 100-150t/day
• Steel removal: 20-30t/day
• Material recovery: 80-90%
• Best practice completion: 250m³/day
• Average cost: $800-1,200/m³
• Waste recycling: 85-95%
• Noise limits: 75-85dB(A)
