New technology promises to reduce flat construction time to less than a year

Almost 66% of the 6,368 low-cost homes being built under PM Narendra Modi’s LightHouse Initiatives (LHPs) using innovative technologies, which he discussed in his Mann ki Baat on Sunday, have their manufacturers located distant from their actual construction sites.

Indore, Bhopal, Bhilai, and Pune are the factories for a total of 3,284 multi-storey flats being built in Agartala, Lucknow, and Rajkot. Similarly, manufacturers in Nagpur, Pune, Hyderabad, and Bhilai are hard at work on another 1,024 flats under construction in Indore. The majority of the jobs are being completed in controlled manufacturing environments, ensuring that the buildings are completed in less than a year. These pre-fabricated parts are sent to the websites and assembled there.

Current status 

Modi announced on Sunday that he had assessed the real-time status of those projects using live feeds from drones mounted at factories and project sites. The PM announced the pilot projects on January 1 to encourage widespread adoption of new technologies to accelerate development. For the first time, the federal government has launched six pilot housing projects in six cities, leveraging innovative technologies to create multi-story flats with up to 13 floors in just one year, focusing mostly on pre-fabrication technologies. The companies that are currently completing the jobs have guaranteed the PM that they will be completed on schedule.

Because much of the work is conducted in a factory-managed atmosphere, these technologies will provide solutions to a variety of issues such as upkeep, painting the flats, and air pollution at project sites. According to an authority, “development is certainly one of the major sources of air pollution.”

Development techniques

Precast concrete system know-how from the United States and Finland is being used in Chennai to build homes faster and cheaper. Flats are being built in Ranchi using the German 3D development technique, similar to Lego toys. Before constructing the overall structure, each room will be built separately. Monolithic concrete construction technology from France is used in Rajkot to produce dwellings strong enough to withstand natural calamities. Similarly, Canada’s expertise is being applied in Lucknow, which will not necessitate the use of plaster and paint.

In Agartala, homes are being built with metal frames to withstand earthquakes, thanks to New Zealand’s expertise. This technology is best suited to places where earthquakes are most likely. Due to the poor soil conditions at the location, piling to a depth of 30 metres has been completed for structural security. “There was a period when it could take years to finish even a little development,” Modi said, highlighting how new technology can speed up home construction. However, the situation in India is changing today as a result of technological advancements.
