Fifth degree of flexibility

The last way of adaptation of an existing building to meet changing circumstances is by demolition to give place for a new building when structural modification is not economically possible.

When considering the type of structural system to adopt for a projected new building, ease of demolition should be included in the cost analysis. Steel-framed buildings can be demolished quickly, at moderate cost.

demolition n. снос (здания)
