Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

With regards,

A Roof Over Every Head ?



Following are the targets for constructing  “ AFFORDABLE HOUSES “  :
-------------------------------------------------------------------------------------------------

TARGETS :

#   Maharashtra  /  1.1 Million  /  2015 - 20  /  602 per day

#   Gujarat         /  5  Million   /  2013 - 18   /   2,740 per day

#   Centre         /   20  Million  /  2015 - 22  /  7,827  per day

These targets were set 2 years ago ( 4 years ago in case of Gujarat )

No one knows how many actually got constructed in past 2 years

My guess : Not more than 5 % of the pro-rata targets !

---------------------------------------------------------------------------------


WHY  ?

·         Lack of political will / Vested interests / Losing scope for bribes   

·         Lack of latest technology

·         Honest officers shying away from taking bold decisions for fear of getting one’s head chopped off by CVC / PAC / CBI / JPC / you name it !

-------------------------------------------------------------------------------


WHAT LATEST  TECHNOLOGY ?


Constructing houses using 3 D Printing Technology

In case you missed, DNA ( 07 March 2017 ) carried following news :

“ 3 D  printed house takes a day to build , lasts 175 years “

The structure , which cost just over Rs 6 lakh to construct, was printed using concrete ink at the build site

One of the best recent examples of this is an entire 3 D printed home recently erected in Russia . Local technology company Apis Cor { http://apis-cor.com/ }  printed a 400 sq ft ( 37 sq mt ) home from scratch, using an on-site mobile printer , in just 24 hours

The main components of the house , including the walls and structural foundations, were printed using a concrete mixture. Other pieces like the windows and internal furnishings were added later on, as was a new coat of paint to the exterior of the house

All told, the total construction cost of the house added up to $ 10,134 ( approx. Rs 6,76,550 )

The house features a hallway, bedroom , living room , and kitchen

According to the company, it can last up to 175 years



HOW  TO  GO  ABOUT  ?

Read my following earlier blogs / emails :


·         Building  Castles in  the  Air  ? ( 25  July  2015  )


·         A  Dream House  by  2020  ? (  01  Sept  2015  )


·         A Quantum Jumpof 50 Million Houses ?  ( 13  Feb  2016 )


·         A  3 D printed  Office  ( 27  May  2016  )


·         A  Good Policy :  Devil  is in  details  ( 10  Dec  2016  )


·         Future  Home is  Here  ( 02  March  2017 )


IMPLICATIONS  :

If  targets  have to be met ( even by 2025 ) , there does not seem to be any viable alternative , other than 3D printing of houses


Without doubt , adoption of 3D printing technology is bound to have major implications for the following aspects of our Construction Industry :

·         At Rs 308 billion , it contributes 5 % of our GDP

·         It garners 40 % of India’s “ Development Investment “

·         It employs ( directly + indirectly ) , some 35 million persons ( 16 % of our working population ) – including 23 million persons employed in our Brick Kilns ( which will disappear with the arrival of Concrete Ink )

·         There are 500 companies manufacturing Construction Machinery ( who will need to “ re-invent “ themselves ! )



 NOW  IMAGINE  THIS :

Only a few weeks back , Elon Musk ( Tesla ) , unveiled “ Solar Roof Tiles “ , to replace normal roof tiles on buildings

These tiles incorporate Solar PV cells and will generate enough electricity for the building

No other maintenance required other than occasional wash !

And Tesla’s POWERWALL battery pack will store the electricity produced during the day , for use at night !

I imagine that one day soon , Elon will team up with Apis Cor ( Russia ) and WinSun ( China ) , to make that 3D printer lay down Solar Roof Tiles , automatically ,as the final layer !
