Noida twin towers demolished in 12 seconds, what next?

India

oi-Deepika S

Noida,
Aug
28:
It
took
12
seconds
to
raze
Supertech
twin
towers
in
Noida
to
the
ground
on
Sunday,
said
Jet
Demolitions
Managing
Director
Joe
Brinkmann.
While
the
twin
towers’ demolition
largely
remained
successful,
a
boundary
wall
of
a
nearby
residential
society
suffered
damage
while
windowpanes
of
several
apartments
developed
cracks.

Local
people
watched
from
vantage
points
picked
days
in
advance.
Many
others
had
travelled
to
Noida
for
what
could
be
a
once-in-a-lifetime
spectacle,
as
3,700
kilos
of
explosives
bored
into
the
pillars
and
walls
of
the
two
residential
buildings
went
off
in
quick
succession.

Now,
the
next
big
challenge
for
the
Noida
officials
is
to
clean
the
mountain
of
debris
generated
due
to
the
blast.
An
estimated
55,000
tonnes
of
debris,
including
concrete
rubble,
steel
and
iron
bars
will
be
dumped
at
designated
areas.

The
process
would
take
three
months
to
be
disposed
of.

Where
will
the
debiris
go?

• The
  post
  demolition
  debris
  would
  be
  managed
  scientifically
  as
  per
  rules
  and
  guidelines.
  A
  final
  decision
  on
  it
  would
  come
  from
  the
  regional
  pollution
  control
  board
  which
  is
  examining
  a
  report
  from
  Edifice
  Engineering
  on
  debris
  management.

• Around
  21,000
  cubic
  metres
  of
  the
  debris
  would
  be
  moved
  out
  and
  dumped
  at
  an
  isolated
  land
  measuring
  five
  to
  six
  hectares
  in
  city’s
  work
  circle
  seven
  limits.

• The
  remaining
  would
  get
  accommodated
  in
  the
  basement
  areas
  of
  the
  twin
  towers
  where
  a
  pit
  has
  been
  made.

• The
  Noida
  Authority
  has
  a
  construction
  and
  demolition
  waste
  management
  plant
  in
  Sector
  80,
  with
  a
  capacity
  of
  300-tonnes
  per
  day.

• However,
  considering
  the
  rubble
  that
  would
  be
  moved
  out,
  it
  is
  still
  not
  clear
  whether
  it
  would
  be
  processed
  there
  and
  if
  yes,
  then
  how
  and
  over
  what
  duration
  of
  time.

• Around
  1,200
  to
  1,300
  “truck-loads”
  of
  debris
  would
  have
  to
  be
  moved
  out
  from
  the
  site.
