Table 3 Comparisons of popular demolition methods

From: Deconstruction waste management through 3d reconstruction and bim: a case study

Method Description Advantages/Disadvantages
Implosion Explosives used to cause the building’s support structure to fail and the building to collapse. • Do not need BIM.
• Construction material not separated.
• Not a technique to be used to demolish only part of a larger building.
• Creates a great deal of dust, vibration and noise.
Crane and ball A heavy ball is swung into the building shattering its structure. • Do not need BIM.
• Height limitations.
• Construction material not separated.
• Not a technique to be used to demolish only part of a larger building.
• Creates a great deal of dust, vibration and noise.
High Reach Arm Demolition equipment, such as hammers and shears, are attached to an arm consisting of several sections or a telescopic boom. • Do not need BIM.
• Height limitations.
• Needs a favorable building shape.
• Not a technique to use to demolish only part of a building.
• Creates a great deal of dust, vibration and noise.
Rope pulling Cables and wire ropes are attached the structural members which are then pulled down using a winch or tractors • Do not need BIM.
• Needs a significant amount of surrounding room.
• Construction material not separated.
• Not a technique to be used to demolish only part of a larger building.
• Creates a great deal of dust, vibration and noise.
Selective Demolition or strip out This process allows the staged selective demolition of both the interior and exterior portion of a building. Interior equipment, walls, floor, ceilings and exterior components can be separated. • BIM assists with providing maximum separation of waste types.
• Achieves the highest production of recyclable material.
• Can be used on part of an existing building and is the safest method for use in an urban environment were a building may be partially occupied.
• Minimizes noise, vibration and dust.
• Takes the longest and may be the most expensive.
