Precast Technology Ensures Quick And Good Quality Construction
R.K Arora, Chairman, Supertech Limited, shares his views on the change in conventional methods of construction in India, and the advantages of precast in construction processes, in an interview with Civil Engineering and Construction Review.
Civil Engineering and Construction Review: What is the Supercast?
R.K Arora: Supertech Precast Technologies Pvt Ltd is Supertech groups’ endeavour under the brand name of Supercast. Supercast is into precast technology in which concrete is cast into a reusable mould, cured, transported to the construction site and lifted into place as compared with conventional cast-in-situ construction.
Supercast uses cutting-edge technology in precast manufacturing considering all the quality standards ensuring that the finished product is as desirable.The manufacturing facility for Supertech Precast Technologies Pvt ltd (Supercast) has been set up at Greater Noida with a production capacity of 5 million sqft per annum inclusive of precast structural elements and hollow core slabs.The facility has in turn been divided into two units, first being shed-A, which is dedicated to produce hollow core slabs on the other hand shed-B is used for production of precast wall panels.
CE&CR: How different is construction by precast compared to conventional methods of construction?
R.K Arora: When comparing conventional construction with precast concrete construction, the major difference is time; precast construction can save you time on-site. Precast construction naturally works heavily with the design team in early stages of the project development, and these efforts up-front will save time and money for the overall project schedule in the long run.With layout coordinated up front the building process can be accelerated, which will get the building covered faster than traditional construction. Plus, precast walls can be erected in all temperatures versus having to heat and hoard for your usual construction methods in the winter months. This saves time on the project, which in turn saves money.By accelerating the project calendar, this can also save the project money by reducing the amount of general circumstances that are essential for the overall project.
CE&CR: Is the precast technology an aid in the better execution of urban housing?
R.K Arora: Housing as an industry is still hand-crafted and deeply reliant on manual labour and on-site construction, which leads to large amount of material wastage, labour inefficiency and delay in project delivery. Precast technology has proved its worth by saving a lot of construction time in various parts of the world. The best part of this technology is that it not only speeds up the construction work but also enhances the quality of the final output. Also, it helps in creating bigger carpet area.This technology will help in keeping up the tempo of construction in all seasons. Also, the quality of the output will be better in comparison to the regular brick-and-mortar projects. Structures built using this technology do not need plastering, as this method makes the surface very smooth, requiring very little maintenance. But what’s important is that precast strengthens the overall solidness of the unit, which is what customers look for.
CE&CR: What are the big challenges that you face as a company, which is into the Precast Technology?
R.K Arora: India is experiencing a huge housing crisis today. The current housing shortage estimates to about six crore units. While many other developing countries are belligerent with the housing crisis, many developed countries have restrained this problem with precast concrete technology. Precast concrete construction technology is one of the capable solutions to meet the huge housing demand. The use of precast concrete systems offers several advantages such as fast and quality construction and improved health and safety. Despite these reward, the industry has not gained popularity in India. The lack of consistency, documentation and testing facilities, contractual issues and taxation, non-availability of tools, technology and equipment, incomplete knowledge and lack of government incentives and promotion are some of the major dispute faced by the precast concrete construction industry.
CE&CR: How does your manufacturing facility work? And does it only cater to the Supertech Group? Or can the facility be also used externally?
R.K Arora: We work together to use our widespread industry experience in helping the series of a project so that the potential problems can be avoided before they have likelihood to influence the project. Our input at this stage can help our customers attain more efficient designs that produce cost savings as well as reduce construction schedules. Our dedicated team also offers supervision at every stage of a project, from concept to conclusion. Through consulting with our customers and delivering practical support right from the initial planning and design stage, we can help specify the most suitable Supercast product as per the need. The result – our customers are bright to save money and time both.
Yes, it only caters to Supertech Group.
CE&CR: Are any of Supertech’s current projects using the precast technology?
R.K Arora: Below are our projects the precast technology -
CE&CR: If so, then how differently is precast technology used when constructing building, as compared to bridges, elevated roads, etc?
R.K Arora: Precast concrete is anelegant way to construct any type of buildings, carefully and affordably. Modular precast is one of the world’s most ordinary and resource-efficient ways to build. It ensures fast construction times, high productivity and outstanding quality. Still, requirements for beautiful, modern buildings are not compromised.
In contrast with the very slow and labour-intensive cast-in-place method, Prefabrication of any structural component off-site during highway construction (or reconstruction) offers major time and user cost savings in contrast with the traditional cast-in-place methods of construction. Precast prestressed road pavements’ technology offers dramatic increase in strength, while it also substantially decreases the construction time and the user costs. It also brings considerable safety advantages, lowers disturbance to traffic and amplify overall convenience for the road users.
