Perfect match of precast and affordable housing in India

There is huge housing demand all over India. Already over 30% of India’s population, that is over 377 million people, lives in urban areas. The urban housing shortage has been estimated to be 25 Million residential units at the start of the 12th five year plan in the year 2012.

Residential buildings have the highest market potential, specifically in the LIG (Low Income Group) and EWS (Economically weaker section) housing sector. According to data available with Brick Eagle, a financial services firm for affordable housing in India, the demand for affordable housing in India is around 18.8 million square meters. The size of these units is in the range of 30-50sqmt.

Affordable housing made of precast in India

Affordable housing schemes of the Delhi Development Authority, DDA. 18,000 houses in 3 years delivered. Another project of 27,000 houses in next 3 years.

Now, affordable housing schemes of the Delhi Development Authority (DDA) have approved precast technology for all their future projects and plan to construct 100,000 units every year.

Speedy, sustainable and versatile precast as a solution

Huge demand like this requires new type of building construction solutions. Precast is an optimal choice for those valuing short construction times and reduced lifecycle costs of buildings. That is why high quality, maintenance free precast walls and floors have been approved as the main building material for several major residential, commercial and public building projects in India.

For High Income Group (HIG), Amrapali Group is constructing G+22 and G+33 story buildings in Greater Noida and will develop two major group housing projects in the next four years totaling 35mn sqft. Precast suits well for villas, too. Janapriya Syndicate has constructed both 2B+10 story buildings and many villas in Sainikpuri, Hyderabad.

In South India, the KEF Company, is constructing a 500 bed hospital and many schools as part of the philanthropic interests of the company’s founder and chairman using precast concrete technology.

Profitability by professional precast building concept planning

The biggest bottleneck in the implementation of precast technology in India is a lack of experienced professionals (architects, structural designers etc.) who have worked in precast concrete building construction.

However, with the increase in the use of modern construction techniques, there are many consultants now in India providing these specialized services. Elematic also provides end-to-end structural design services with a dedicated design team based in Pune, Maharastra.

Beautiful and safe precast in Russia – with Love!

#precast #buildings

Atmosfera housing project by YIT in Russia

Russia has been a central part of my life for the 21 years. My first experiences with this great country date back to 1990´s when I moved to St. Petersburg to work there. Since then many things have changed, but also many things have remained the same.

Building construction in Russia 

In the early 90´s St. Petersburg was a typical ex-Soviet city where the economic growth was taking first steps. Many western companies started investments and opened subsidiaries in Russia. People began to move in to big cities searching for jobs and a better standard of living. And it is still going on.

The need of new flats is huge in all major Russian cities:  in Moscow they are building 4,5 million SQMs/year and in the Moscow about 5,5 million SQMs/year. In St. Petersburg and other big cities the annual volume of built housing is from 1 to 3 million SQMs.  In 2010 there were 714 000 completed homes in Russia.

Precast concrete building traditions

New precast factory of YIT in Russia

It is clear, that such huge building volumes put a great challenge to constructors to find the most cost effective way of building. Russia has a long history with precast concrete buildings. The value of this ready-to-install building product has been recognized widely. Old problems related to the quality of precast products and buildings can be easily solved with modern building methods and precast manufacturing technologies.

Effective building construction

#precast #piles

Precast concrete piles for safe and sustainable foundations

The typical size of supplied precast factories can vary from 100.000sqm- 500.000 sqms of housing per year. Less manpower is needed thanks to more and more automated processes and advanced technologies. Using prefabricated concrete products allows the constructors to maintain the high quality of houses even when building during the wintertime. The modern precast connections can be made safely in temperatures even up to -20 degrees Celsius.

Precast concrete pile production line

Many big Russian cities are located on river banks and see coasts. In such conditions houses must be built on pile foundations. Elematic has developed a unique production plant for foundations: it is possible to produce even 3 KMs of piles/day on a single plant. This is not possible using other solutions on the market. In St. Petersburg we have a client, who has recently bought a 3rd such line. This is just one example of the great market opportunity waiting for modern precasters.

Can precast be inspirational and beautiful?

Precast housing reference

Apartment building with a graphic concrete facade in Espoo, Finland. Construction year: 2013.

This question we are often asked. Our answer is definitely yes! I’m glad to notice that this thought is more and more widely accepted and also applied around the world.

Since the late 1990s Graphic Concrete  has been working with projects ranging from industrial buildings to schools, hospitals and commercial and residential buildings.

Industrial precast building

H.A.N.S., Industrial Precast Building, Czech Republic. Construction year: 2009.

Our core idea is to create premium precast concrete surfaces and that way inspire people in their everyday environments. Preferences vary from a region to region. When Southern European and Arabian consumers prefer strong and clear ornaments on their building surfaces, Northern Europeans are more into non-figurative patterns and textures. One of the top surfaces has lately been nature in its various representations.

Graphic concrete

Example of an ornament as a graphic concrete surface figure.

We call these surfaces graphic concrete – according to our patented technology. We offer a real industrial and cost efficient product for large-scale surfaces, which can also be visually creative.

Precast slabs

Sample slabs with graphic concrete surfaces

Today the technology is a proven concept within the prefabrication concrete industry. Versatile buildings demonstrate the vast range of graphic concrete applications in e.g. facades, walls and pavement slabs. All these are possible without compromising the uniqueness of a building and the vision of an architect.

One important point is, that graphic concrete is not an additional cost. Every precast concrete facade or wall has always a surface. So it is more a choice between inspirational and monotonic surface than anything else.

Precast production lifecycle, part 1

Setting-up a profitable precast production is not a piece of cake. Instead, it is a quite complicated puzzle with contradictory interests of city planners, architects, investors, builders, precasters and most of all – users of the buildings. Or is it so?

Precast as a building method

It is only precast that enables building of large open areas without partition walls. Or creation of public schools with world-famous waterproof art on the facades.

Building construction planning

Precast can be amazingly flexible building method. Cooperation of architects, structural designers and technology developers has concretized most innovative buildings in the era of industrialized building construction.

Close cooperation of architects, structural designers and technology developers create innovations

When designing modern minimalistic villa or busy business center, precast is a choice of pragmatists. Precast walls are sound insulated and fire and moisture resistant. Precast also reduces need for cooling and heating.

Precast saves materials and resources in the building phase. In structural design, cooperation with precast technology supplier can actually save money in the building process.

Precast as a building method

Precast production investment is as heavy as you want. There are multiple precast products and production options. You can build the whole house with precast. You can also set-up the whole production outdoors or have it totally automated. Or then you can acquire only one tilting table for a small-scale production of varying  precast products.

When the demands of factory capacity, flexibility and level of automation are clear, precast technology and machinery supplier can provide you with preliminary production plan. As a one-stop-supplier, Elematic can also support in finding the best production practices.

Urban China – fast city development from scratch

Shanghai Buildings by precast

Precast houses fit perfectly to Asian milieu

While visiting Shanghai and Beijing last month I couldn’t stop wondering the speed of evolution of cities. Around every corner you could see massive building construction sites reaching the sky. At the same time, most beautiful urban quartiers showed the best of modern city life.

Precast buildings in China

Commercial and apartment buildings made of precast suit well for the needs of fast urbanization

China has more than 150 cities with over 1 million inhabitants. Country’s urban population exceeded that of rural areas first time in 2012. China Radio International announced that over 700 million people, which is over 50% of population live now in the cities. In next 20 years, another 300 million people would need their own city home. Quite a challenge for building constructors, I would say.

How to maintain cities’ functionality in the middle of construction?

Not surprisingly, China is also the largest automobile market in the world. Nearby 220 million registered motor vehicles are an integral – and painful – part of every city. Together with cars, foreign direct investments target China more than any other country in the world bringing their own needs to the city building.

All these developments must push the limits of cities’ functionality. Fluent traffic, easy access to public transportation, working sanitation and sewage systems, comfortable social areas and approachable services. Not to mention good sustainable living conditions of city people. These are some challenges that came to my mind when reflecting the situation from European perspective.

Precast as a smart building solution

In this context, precast could be the smart solution. It offers undeniably fastest way to build and make a new city function. Precast manufacturing facilities are scalable to varying building demand. As a building type precast is tested  in practise in the largests cities around the globe.

Precast suits as well to affordable housing as to unique public and commercial constructions. It is cost and environmentally aware building method with minimized logistical flows during construction. Also, labor and lifetime maintenance needs are quite modest.

Precast concrete – mirror of the times

What comes to your mind, when you hear the word precast? Massive housing projects in Russia, charming Caribbean villas or maybe the tallest man-made structure of Burj Khalifa in United Arab Emirates?

All three constructions – even so different – represent the society they serve. They are born from the visions and needs of local people,  politicians and businesses. They are realized by international financiers, architects, builders and manufacturers. They are evaluated by future generations, most likely with laugh and surprise.

Precast buldings worldwide by YIT
Precast was developed in Scandinavia, Northern Europe, already in the 1950s. Since that, we at Elematic have been lucky and determinded to develop smart manufacturing solutions for precast products. Nowadays, wide variety of walls and floors are available for the building needs of changing societies. Precast is the most common building material in the world.

This blog is created to better listen and interact with all interested in precast concrete. Through this blog we share our experiences and reflect precast insights. We want to strech our thinking, so please be critical and challenge us!
