DEMOLITION

3. High Rise Building
4. Controlled Demolition
Outline
Introduction
Demolition is the tearing-down of buildings and other structures.
Low rise buildings is by pulling down either manually or mechanically using
hydraulic equipment, elevated platforms, cranes and excavators.
High rise buildings are demolished using controlled explosives or by
hydraulic breakers.
Demolition
Permit approvals
Method statement submission
Protection works
Existing utilities termination
Notifications
Safety document submissions,
approvals and briefing.
Removing hazardous or regulated
materials.
Sequence of demolition based on
technical considerations.
Demolition of Low Rise Building
Hydraulic excavators are used to topple
one- or two-story buildings by an
undermining process.
The strategy is to undermine the building
while controlling the manner and direction
in which it falls.
The demolition project manager/supervisor
will determine where undermining is
necessary so that a building is pulled in the
desired manner and direction.
Walls are typically undermined at a
building's base.
Demolition of High Rise Building
High reach demolition excavators are more often used
for tall buildings where explosive demolition is not
appropriate or possible.
Excavators with shear attachments are typically used to
dismantle steel structural elements.
Hydraulic hammers are often used for concrete
structures and concrete processing attachments are
used to crush concrete to a manageable size, and to
remove reinforcing steel.
The "inside-out" method is used, whereby remotely
operated mini-excavators demolish the building from
the inside, whilst maintaining the outer walls of the
building as a scaffolding, as each floor is demolished.
Controlled Demolition of High Rise Building
Large buildings, tall chimneys, bridges, and increasingly some smaller structures may be destroyed by building implosion using explosives.
Imploding a structure is very fast—the collapse itself only takes seconds—and an expert can ensure that the structure falls into its own footprint, so as not to damage neighboring structures.

Bubble Foam Machine
For effective dust
suppression
By combining air,
surfactant, and minimal
water into a highly efficient
foam chamber, foam is
generated and discharged
through chute nozzles.
