Construction Technologies that will make a�?Housing for Alla�� a Reality by 2022
Developers of affordable homes in India are faced with multiple challenges and the requirement for swift execution and consistent quality of construction is the biggest of the lot. With the scale of a typical affordable housing project, low-wastage and speedy construction are vital to achieving the volumes in the prescribed period, as any delay in completion leads to cost escalation. The solution lies in innovation and technology and using it consciously to deliver quality products.
Technology is a significant enabler of construction speed, cost-optimisation and quality. Certain building materials and ready-to-fit techniques can boost productivity while enhancing quality, improving speed and reducing waste. New advances in technology enable meticulous conceptualisation during the pre-construction stage, promoting efficient use of labour and materials as it lowers uncertainty in executing construction and timely delivery.
From the Wall systems to the foundation, every element of the structure is advancing.
Mahindra Life space Developers tied up with IIT-Madras and discovered trench foundation technology, which allows the building to have sheer walls that are covered with an envelope of lightweight blocks. Instead of conventional shuttering, Puravankara developers have upgraded to a�?Mivana�� an aluminium wall formwork, used to build walls and slabs in one continuous pour of concrete, cast monolithically. To replace the heavy brick wall, Precast flat panel system, 3D volumetric construction, tunnel form, hybrid concrete construction, thin joint masonry, and Cellular Lightweight Concrete (CLC) are emerging options. Tile adhesives have replaced mortar for flooring, and doors, windows and fittings work on the basis a�?ready to fita�� components. Kitchen platforms can be built in three hours by mounting marble over mild steel box sections.
The a�?structurea�� base of the building is where technologies are really playing out, such as in the case of precast. Though having huge potential, it isna��t fully tapped in the country yet, believes Amit Pal from Mahindra Lifespace Developers.In terms of technologies of the future, 3D printing, which is making an entry into India, has proven that a house can be built in 48 hours. Sapoorji Pallonji Engineering and Construction is at an advanced stage of adopting 3D precast technology in some of their projects.
