3. Introduction
 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.For
the protection of public safety
and to ensure adjoining
premises and the site are made
good on complection.

the help of some equipments or
any other method.
 When explosives are used for this
then the demolition process are
called as an implosion.

5. Steps before demolition
Surveying
Removal of dangerous material
Preparation of Plan

6. Surveying Study of different
parameters of the structure
and its surroundings.
Record Drawing
The construction materials
Adjoining properties and
site condition

7. Removal of dangerous material
 Asbestos containing material
 Soil contamination material

8. Preparation of plan
The location of the building to be demolished .
A layout plan of all floors of the building to be
demolished.
The structure support systems.
Time and frequency.
A temporary parking layout for mobile machines and
trucks.

of the building below that
point.

building,height of building and economy.
Anyway controlled demolition of building is necessary
to ensure safety.
