Construction 3D prints India's first building with reinforcement / Business Standard / 25 Dec 2020
L&T Construction,
the construction arm of the $21 billion technology, engineering & construction conglomerate,
Larsen & Toubro, has 3D printed
a G+1 (Ground plus one) building with reinforcement for the first time in India.
With the country aggressively pursuing
the objective of creating 60
million houses under the Housing for All by 2022
programme, this achievement will certainly give a huge fillip to the mass housing segment, said
the company.
“3D concrete printing is one of the
technology disruptors with the potential to radically redefine construction methodologies
and I am extremely happy that by demonstrating our growing expertise in 3D
printing, we are well positioned to push the boundaries of automated robotic
construction,” said M V
Satish, whole time director & senior executive vice president
(Buildings).
He added, 3D printing will not only accelerate the pace of construction, but also significantly improve
build quality.
The 3D
printed building, which has a built up area of 700 sq. feet and is located at L&T Construction's
Kanchipuram facility, has been built with a special, in-house developed
concrete mix using indigenously available regular construction materials.
The building was printed with both
vertical reinforcement bars and horizontal distributors using welded mesh, that
satisfy provisions in the Indian Codes and optimise the cost of construction.
Barring the horizontal slab members,
the entire building structure was 3D printed ‘Cast in Situ’ at the
job site in an ‘open to sky’ environment within 106 printing hours,
using a fully automated 3D printer.
3D printing is a process, in which the
material is printed under computer control to build a 3-dimensional product,
typically layer by layer. It is predominantly used in manufacturing industries
to print rapid prototypes, complex shapes and small batch production using
special polymers, metal alloys etc
3D printing with concrete is still
largely work in progress across the globe.
Earlier in November 2019, the team had
3D printed a 240 sq. feet, 1 BHK
apartment, in line with typical EWS building layout, to explore the
feasibility of this innovative technology

I urge you – and your team – to relentlessly pursue this 3D
Printing technology, which I have been advocating to our Policy Makers for the
past few years, as can be seen from my following 23 emails to our Cabinet Ministers / NITI

Dear
Shri S N Subrahmanyan
( MD – L&T / sns@lntecc.com
),
This innovation of L&T can lead to :
Ø
Revival of Construction Industry , in turn growth
of feeder industries such as Steel Rebar / Ready Mix Concrete ( RMC ) / Cement
/ Glass / Wood / Tiles / Marble etc
Ø
Creation of lakhs of jobs in these feeder
industries ( although 3D Printing of houses may not increase many jobs since
process is AUTOMATED )
I urge you to consider the following :
Ø
Persuade Education Minister for Introduction of following subjects in all Civil Engineering Colleges ( and a lighter version in our 15,000
ITIs ( Industrial Training Institutes ) ,
# “ 3D Printing “
# “ PRODEVSYS – Project
Development System “
Ø
Grant “ Manufacturing Technology Licenses “ for
3D Printing tech developed by L&T to hundreds of Construction Companies of
India, on a nominal license-cum-royalty fees
Ø
Facilitate adding into the technology, following
features :
# Roof-top Solar Power generation with Reverse Metering ( or TESLA type
#
Tesla type POWERWALL solar
power storage devices in each flat
#
Smart Electric Meters
# Plinth level EV Battery Charging outlets
# Internet connected Smart Water Meters for each flat / tenement (
instead
for building )
#
Rain water harvesting / Drain water recycling
# Segregation of dry and wet garbage ( possible composting / bio-gas
generation )
