*Four die in building collapse*

VISAKHAPATNAM: Four workers died when the slab of a building which is under
construction, collapsed in Sector 6 of Ukkunagaram.

Four others were reportedly buried under the debris and at least eight
others were injured. They were admitted to a local private hospital. The
condition of some of them is stated to be critical.

According to the police, workers were constructing walls on the first floor
of the building when the slab of second floor caved in, bringing down the
entire structure. Police and civic authorities rushed to the spot. The
debris is being cleared using earth-movers. Most of the victims were daily
labourers.

Prima-facie cause of the collapse should be
advised.How did the Slab fall.Removal of scaffolding
before attaining strength or some other cause?.The
information should be complete at least on first study

Dear Friends,
Incidents like this should shake up our conscience and should make us do
introspection and self-improvement...at least in design offices where
designs carried out by  semi trained design engineers are being sent out for
execution, under stress by Clients and due to lack of enough time at
hand....the modern day mantra being WE WANTED IT YESTERDAY...This becomes
specially important in the light of many softwares (like STAADPRO) not
declaring a Beam unsafe in case it fails in deflection, and at times this
may become a very critical factor, architects always keep pressing for a
reduction in beam depth and create a lot of pressure to reduce structural
sizes in general.
Besides the quality of scaffolding and its design also becomes very
important, especially in large spans. In addition, at every site, a chart
for minimum waiting period before removal of scaffolding for each stage
should be discussed with the contractor, and prominently displayed (and
religiously followed)
regards
sangeeta wij

Dear sefians,

it is a tragedy that buildings collapse even during
construction;  not exclusively in our country alone
but all over the world (Ref:  the note from Er. Hari).

Construction is a job different from that of design
and analysis, and calls for specialisation.  While
analysis and design are taught in engineering schools,
barely any attention is accorded to constructional
aspects of structures.  The result is exclusion of the
elite designers from the mundane construction jobs
left to mistry or raw graduates and diploma holders
with predictable consequences.

University curriculum should be updated to include
construction (particularly formwork and concreting)
aspects as well.

In view of the rapid strides in technology and
structural systems, a four year degree course appears
to be inadequate to impart training in current
materials and developments.  A five year degree course
may be more appropriate these days in view of the
extensive research and developments, and accumulation
of vast information.

Dear all,
I fully agree and endorse the view point of Sangeeta. She has correctly
pointed out the  ' morden things" and the mantra - We Want it Yesterday!

Dear Sefians
In my onion one can remove scaffolding as soon as the work is completed scaffolding in no way holds the structure since it is “A platform built against the side of a building
for the support of workmen”, where as shuttering is responsible for most of such mishaps. Design failure is tested during earthquakes or other shakes. such failures are due to inexperience ness of the site engineers. I remember the failure of the bridge deck slab, in that case whole shuttering was rested angle iron boxes that were directly placed in canal bed, and longitudinal girders were on dry bricks (so that girders can be removed easily). Due to sinking of one support in canal bed, the load crossed the brick’s crushing strength the whole shuttering loaded with fresh concrete lost the stability, and sank into flowing water the engineer at top trapped in reinforcement bars and could not survive. Most of the senior engineers don’t visit the site(better to say most of the structures are built in the absence of engineers). Safety of workers for us is no priority. Basements are constructed in old building while standing tall. Walls collapse the matter is sorted out with in
30-50 thousand if it is not highlighted.
