Offsite construction with precast technology, modular rooms and readymade washroom pods is emerging as a major disruptor in the construction sector. Ensuring 50% saving on time, close to 30% material conservation and substantial reduction in noise and dust pollution, the future promises to be ideal for factory-manufactured homes amid rising concerns over environment.
Bengaluru would see the first full-fledged offsite constructed residential project coming up in Yelahanka on a 11-acre plot adjacent to the CRPF camp. Being built by Vaishnavi Group in partnership with Katerra, a technology-driven global company, the project comprises 896 apartments. Named ‘Vaishnavi Serene’, it has been conceived as a ‘Design for Manufacturing and Assembly’ (DfMA) project.
Introducing the project, C.N. Govindaraju, MD, Vaishnavi Group, said it will be a pioneering project with the offsite technology offering one-, two- and three-bedroom apartments ranging from 635 sq.ft. to 1118 sq. ft. dimension. He said that with the coming of the RERA, compliance with the delivery schedule was of critical importance.
Nejeeb Khan, Head-Design & Business Strategy in India for Katerra, said China has begun mandating offsite construction due to the resource-conserving nature of the new technology where 95 % of the construction happens away from the site, thereby cutting down on noise, dust and usage of water. He said since concrete slabs are steam-curated, water spillage is completely avoided. The concrete strength at M-50 would be of higher order.
Mr. Khan, who is a member of the American Institute of Architects, said offsite construction will be the go-to technology in the years ahead as it promises 12% to 15% cost efficiency owing to saving on time factor and engagement of fewer labourers.
Asked if the technology would be suitable for multiple-floor buildings and affordable housing, he said the company was in talks for an affordable housing project where housing units would go upto 10 floors under PMAY scheme. He said the buildings would be quake-proof and can withstand vibrations such as in proximity to highways, airports and quarries.
