Security Measures Adopted for Brazilian
Implosions: pre-demolition simulation and
analysis, protective nylon screens against flying debris
and isolation of the area

ASI Demolition Analysis
A NEW Level of Realism:• Verify/Optimise demolition plan• Reduce cost from accidents• Multiple perspectives of the planned demolition• Anticipated footprint of collapsed structure• Accurate perimeters to protect neighboring
structures• Deconstruction stress analysis• Wind analysis of weakened structure prior to
demolition• Seismic vibration analysis of falling debris• 3D Graphics generated for presentations to client,
government & public.
• Increase Safety

ASI Demolition Simulation
Post-Demolition
Pre-Demolition Analysis
Forensic Analysis
Side-by-Side Comparison
Plan Evaluation:• Implosion• Pulling
• Wrecking Ball• Deconstruction
Hazard Assessment:• Seismic• Wind (Weakened Structures)• Surrounding Structures
