The core difference
Demolition brings a structure down efficiently, accepting that most material becomes debris. Dismantling takes the structure apart in reverse construction order so materials remain usable.
When demolition makes sense
Concrete-heavy buildings with little recoverable material, sites with good machine access, and projects where speed matters most are usually straightforward demolition candidates.
When dismantling makes sense
Steel sheds, structures with valuable joinery or roofing, tight sites where impact breaking is unsuitable, and cases where part of the building must remain in use favour dismantling.
Combining both
Most real projects use both: recoverable elements are dismantled first, then the remaining shell is demolished mechanically. The balance between the two is a commercial decision as much as a technical one.
