A fully automated building construction technology, wherein a robotic printer prints or deposits the concrete layer-by-layer without any supporting formwork system, it uses an in-house developed concrete mix, for which patent has been applied. L&T will be using the technology for building affordable houses, villas, constructions in defence areas and G+3 government structures.
M V Satish, senior executive vice president (buildings), L&T, on Monday said they were in discussion with the Centre and state governments, besides developers to deploy the technology in their respective infrastructure. “The biggest advantage is that the 3D technology consumes only 30% of time for construction when compared with conventional construction technology. It requires lesser workforce, as well,” he said. Noting that this is the future of constructions, he said, research and development is being carried out for using the technology for building taller structures.
The 3DCP was used as a trial for buildings at its Kancheepuram facility, following which it is constructing a model house in an area of 1,300 sq ft at Manapakkam to showcase the technology. L&T has obtained Performance Appraisal Certification Scheme from Building Materials and Technology Promotion Council, Union ministry of housing and urban affairs for developing low rise buildings.
