• We know every structure is designed for a life period.
• The existence of the structure after the service life period is
very dangerous to its occupants and surrounding buildings.

authorities to control demolition works for the protection of
public safety and to ensure adjoining premises and the site are
made good on completion of the demolition. 2

point will fall down on the part of the building below
that point.
