Developed India is building with practical precast
“Indian construction industry is mature and has its set practices and systems. However, now precast building is really booming in India as it is becoming an acceptable technology,” confirms Mr. Chander Dutta, head of Service Masters, Elematic's representative for India.
There are several reasons for why precast building technology is rapidly gaining a foothold in the Indian market. First of all, socio-economic development means that the demand for affordable housing is increasing fast. The precast industry is currently concentrating on the “Affordable homes” concept. The Indian government is planning to provide subsidies for builders to meet the shortage of 25 million affordable apartment buildings. Precast is increasingly popular also for commercial projects.
Secondly, government regulations are changing in such a way that they favor precast because of its advantages compared to other building techniques; it is affordable, fast, and safe. The schedules are always tight in the construction business and precast makes it easier to stick to project timelines and eliminate unexpected interruptions in work.
From 2007 to November 2011, Elematic has sold six precast factories in India. Of these six, four are already fully operational. The first in line, VME Precast in Chennai, is already planning an expansion of its facilities to accommodate the increasing demand for precast products. VME produces hollow-core slabs, beams, columns, and wall panels. The current capacity is 200 000 m² of hollow core slabs per year, and doubling this up to 400 000 m² is already under negotiation. In Delhi, one of Elematic’s clients manufactures solid slabs, precast columns, and beams for an 18 000-unit apartment block.
Janapriya in Hyderabad has been manufacturing wall panels and staircases since October 2010 with a capacity of 250 000 m². The biggest unit so far, Amarapali in Noida, is currently under construction and due to be ready in March 2012, and will produce hollow-core slabs and wall panels with a capacity of 400 000 m². Elematic has also delivered precast factories for B.G. Shirke (solid slabs, 210 000 m²) in New Delhi and B.E. Billimoria (solid slabs, wall panels, staircases, lift shafts 200 000 m²) in Pune.
Practical precast meets nature’s requirements
India’s geographical position poses some challenges to the construction industry. Seismic activity is the most worrying natural threat the building industry has to take into careful consideration. The precast industry offers solutions that have been widely tested in real conditions. Precast is a safer and more durable option for building technology than some of the traditional methods that are still widely used.
The rainy season lasts for four months, creating additional challenges for the building project management. Precast parts can be manufactured in surroundings where the effects of rain and other weather conditions can be eliminated.
Precast technology has been proven to be a good solution for work safety. Like many other countries, India is also facing a shortage of skilled labor in the building industry. Precast is less labor-intensive. An additional advantage of precast is that during manufacturing and installation similar work-routines are repeated. This helps workers to learn and become more efficient, project after project.
Precast technology current usage in India for Housing
A recent our survey of house builders indicates and builders, civil engineers took awareness about precast design, life and flexibility that a range of precast concrete products is in common use within India house building. Some companies have a broad range of experience of precast and some have also studied the potential for panelized or volumetric precast in their designs for houses. The most popular use for precast concrete, however, is in components. This includes walls, beams, floors, columns, panels, & stairs. The benefits of such products for housing are well known. Items such as lintels and cills (The horizontal member that bears the upright portion of a frame, especially the horizontal member that forms the base of a window) are mainly stock items, available in standard sizes, often concealed after first/second fix and very economical when procured in quantity. However, in many instances, other elements of the house construction could also employ precast concrete components, such as walls, ground beams, structural frames, foundations and roofs. The potential to widen the market for precast into these areas is significant. The Future In general, there are three broad categories of use for precast concrete, namely components, panels & volumetric. At present, the house building market in the India is only really taking advantage of just the first of these options, and so the focus of this publication is on the latter two categories.
Indian Civil Construction Companies focuses on the broader issues that could affect the take-up of precast in housing. The findings from recent surveys of the public, house builders and housing associations are presented. There is a body of opinion that supports the notion that traditional materials are the most appropriate and popular for new housing in the India, but there is also a growing interest in different styles and ways of living, particular in urban areas. The surveys presented here suggest that the India continues to prefer heavy weight construction. A discussion of the influence of other market drivers is given; from last five years Indian civil market report and sustainability could have significant impact on the way in which all housing is procured in the future. This Part of the report also contains an account of the current market success of other materials in the prefabricated housing sector.
Indian Construction Market focuses on the use of precast concrete, and considers the history of precast concrete in housing. Clearly there is an argument that precast concrete has a (historical) reputation which to some extent continues to prejudice its use in housing. Reference is made to the current Indian market for precast products. The portfolio of products available both in the India and elsewhere are outlined, and an explanation of the basic types of precast concrete used in housing is also given. The examples of precast concrete from other EC countries show that there is market potential for the product in housing provided manufacturers promote sensible options to a well-informed market. There are clearly lessons to be learned from countries that use a higher proportion of industrialized housing than the India and here examines the key features of concrete in general, and precast concrete specifically. Fire resistance, thermal mass, acoustic insulation and durability are included together with a discussion of cost and value issues. Indeed, take-up of precast may ultimately depend on the balance of construction costs and added value. This difficult equation may need to be resolved on an individual project basis, thereby offering every house building client a bespoke package. For precast concrete to make inroads in the housing market, contractors and clients need to be made aware of the speed and quality benefits it offers, while owners and occupiers need to be made aware of the performance benefits over time such as thermal mass. Other considerations such as services integration and adaptability are related to the future needs of occupants, and procurement strategies are noted. Manchukonda Prakasham Industries India Private Limited official people says next two years they planned to establish precast plant in India and it is one of the Indian largest prestressed concrete product manufacturing company. Next ten years almost all Indian construction companies entered into precast industry.

please send the information to my mail
Dear Mr Bheemesh, What is the perception in India about precast housing as it is being used in affordable or low cost housing and not in higher cost housing.I feel this wud get popular with standarisation so what is the role of industry and Govt in this direction. As a start up who is not in to construction, what should be the entry strategy. Seek your inputs.
we have the complete solutions for Precast, do refer www.avermann.com for info or you'll can email me on ahmed@protoolsme.com

i Think ech you have mentioned only the elematic plant s ,Wat abt the echo
The essence of use of precast prestressed concrete system is architectural flexibility, superior quality, very less labour requirement, ease of construction at site, virtually no wastage of natural resources, environmentally sustainable solution, negligible maintenance etc. at the same time economical life cycle cost.
Construction Industry in India is growing very rapidly since last 7-8 years. Besides need of rapid construction, scale of projects is also increased multi-fold. With higher needs of construction, we are facing considerable shortage of labour at construction sites. With urbanisation, there is been demand of aesthetics, architectural flexibility and quality of construction.
Mechanisation of construction industry is the only solution to cater the above needs. And Precast Concrete Technology is the best suited solution for our current requirement and future needs.
Broadly, precast concrete configuration for buildings are categorised in two ways, column-beam frame structure or wall-frame structure with prestressed precast slabs. For commercial and industrial structures, requiring wall free large spaces, column-beam frame structure is commonly implemented. While for residential buildings, aesthetic point of view and make use of available essential walls, wall-frame structure is commonly deployed.
For buildings, main structural components are precast column, prestressed precast beams, prestressed precast slabs (either hollowcore or solid slabs), reinforced concrete precast structural walls and non-load bearing partition walls.
Mass of structure is critical in context of seismicity in India. The mass of structure contributes to the lateral forces and adds up to the stresses, leading to uneconomical designs. With implementation of prestressed precast components and slender members, the mass of structure is controlled and overall economic design and material savings is achieved. Structural configuration for stability and integrity of precast concrete structure in seismic regions shall be evaluated meticulously. Undoubtedly, precast concrete structures can be used in high seismic conditions and we have vast implementation of technology in all high seismic conditions right from West USA, Taiwan, New Zealand, Korea etc.
We have successfully brought precast concrete technology in India with composite and complete precast structures been constructed in India. We have precast plants India from Elematic technology for production of all structural components viz. walls (sandwich panels and solid concrete), prestressed slabs (hollowcore and solid), column, prestressed beams, staircase etc. These precast plants are tailor made to the client’s need and projects they execute.
DDIPL provides complete technology support from concept design, precast concrete configuration and element requirements, precast plant requirement and commissioning of plant, training of staff for plant operations and execution of buildings. We provide complete engineering solutions for residential, commercial and industrial buildings, having team of experts in precast concrete technology.
We have already implemented precast concrete technology for residential buildings (2 Basement + 10 storey), process industry (15,000 sq.m.), commercial malls (20,000 sq.m.), hostel buildings (17,000 sq.m.) etc. Part of these precast structures are been constructed in NCR with high seismic zone IV of India.
Elematic is one-stop-supplier of the technology. It is world leader in precast concrete technology and you get complete solution related to precast concrete technology under one roof.
Mechanisation of construction industry is the solution for Indian needs and Precast Concrete Technology is the best suited technology.

its just great to note
can i have a price chart? and details of this technology? im planning to build a uniqe house at SIRSI KARNATAKA
Can you pl.sent the details of buildings encluding actual Photos,layout plans and prices for Patna and oblge.I also want to know about your marketing stratg.
can u please email me what are the problems arrive while erecting precast structure in site? and i want to know about it's lateral load bearing capacity
I worked in this field in Qatar after my graduation from nitk surathkal as a factory engineer for 3 yrs. Now I am pursuing an MBA in Operations Management as many people have approached me to set up a Precast factory. In Doha,Qatar we were producing wall panels,Hollow core, Facades, boundary walls, decorative concrete products, beams, columns, and many others. Precast is very very fast if you get the planing right. Time saves money and you save a lot of money. Here the important thing is not is not only just for affordable housing but you can go for any other typical projects as well. Some main advantages include Saving time(You will save a hell lot of time), Money cos of design flexibilities and use of hollow core and insulated panels that reduce your weight on the overall structure and so u can alter your foundation designs. Usage of hollow core reduces ur need for more concrete as it is hollow. Hollow core is a wonder product in precast. It is basically a slab of 1.2m width and length varies. There are thickenss which ranges from 150mm(may be even less) to sometimes as thick as 500mm depending upon the specifications of the extruder machine. Since it is prestressed it has longer span( very imp) can take more loads and ur need for columns can be reduced in area like car parks and halls. Hollow cores can be used a boundary walls and has many applications. Quality control will be very good as the elements are done in the factory environment with very good quality control and limited human interaction. Some of the disadvantages in india could be, access to cranes for erection, transportation of elements in trucks within city,knowledge of design(not much different) knowledge of the product etc. To summarise this will be a big success in india as these days we have problems with completion time, labor and quality. Right now it is best to concentrate on Mass housing and villa projects.
I want to know the details of precast building items and comparative prices in north India (Roorkee area)
I have an urgent Slum Rehabilitation project pilot in East India of around 1000 dwelling units. It will be followed by many such requirements. I am interested to use Precast technology to expedite the construction apart from its other benefits. I want to work with any manufacturer/ builder who can provide design as well as execution services/support. Interested parties may please rush the details ASAP.
