Sourabh Bansal, co-founder and Managing Director, Magicrete, heads the company which successfully completed India’s first mass housing project in Ranchi using the 3-D modular precast construction system. This project, which was completed within 18 months includes 1008 dwelling units and demonstrates cost parity with traditional construction methods while significantly reducing construction time by up to 40 per cent. This not only makes housing more accessible but also showcases the potential of precast concrete technology to revolutionise the construction industry in India. In terms of materials, the project used Portland Slag Cement with a high percentage of Ground Granulated Blast Furnace Slag (GGBFS), reducing the carbon footprint by about 60 per cent. Additionally, M-sand replaced traditional river sand in concrete production, contributing to sustainability efforts.
