During Residential Demolitions, the type of demolition used will vary. The smaller, low-rise, buildings, for example a two storey house, or a bungalow, can and will be demolished by wrecking ball and chain; controlled, explosive demolition tends not to be used within low-rise scenarios.
During the demolition of high-rise buildings, Controlled Demolition (Explosive Demolition) is more cost efficient and overall far safer than ball and chain. Other than the reasons provided, another reason would be because the materials used in high-rise construction need to be far stronger, so they are reinforced.
