Demolition Analysis & Simulation

Demolition has always depended on the experience and intuition of demolition contractors. As newer buildings and structures with complex and unpredictable structural systems begin to be demolished, safety and quality standards are requiring an additional analysis of demolition plans. Until recently, no engineering method existed that could accurately analyze structural behavior during demolition or deconstruction. But, that has all changed with ASI’s unveiling of a new approach for bringing safety, assurance, and clarity to demolition planning.

Simulated Demolitions

Areas of Analysis

ASI Demolition Simulations analyze the behavior of the following structural components:

  • Reinforced concrete structures
  • Steel structures
  • Composite components
  • Masonry structures
  • Rebar detailing
  • Concrete strength
  • Post-tensioned components
  • Prestressed components
  • Precast components
  • External glazing
  • Truss systems

Added Value

  • Reassure skeptics of implosion and deconstruction plans with an analysis-based simulation
  • Test demolition plans by simulating them with an advanced structural analysis software
  • Secure the acceptance needed from the GC, engineering, and public by verifying plans and showing simulations

Description of Services

ASI Demolition Simulations provide:

  • Engineering Reviews
  • Multi-Perspective Views
  • Debris Perimeters and Effects
  • Demolition Footprints
  • Deconstruction Stress Analysis
  • Vibration Analysis
  • Demolition perimeters

“What if” Scenarios

ASI uses advanced structural analysis to perform “What If” scenarios covering:

  • Blast sequence mishaps
  • Ambiguities concerning the behavior of certain structural elements (precast, composites, reinforcement, etc.)
  • Unpredictable structural geometry behavior (towers, bridges, stadiums, water tanks, etc.)
  • Insufficient explosive planning
  • Collateral damage assessment
  • Seismic activity

Required Information

The accuracy of ASI Demolition Simulations relies on the amount of data available. When structural data is unavailable, ASI can redesign the structure per the building codes of the construction year.

ASI requires the following data, whenever it is available:

  • Blueprints
  • Level of deterioration
  • Demolition plans
  • On-site measurements
  • Year of construction
  • As-builds
