Minister of HUPA Mr. M.Venakaiah Naidu said “Speedy, Safe and Sustainable Construction using prefabricated alternative technologies is the need of the hour to meet the targets under Pradhan Mantri Awas Yojana and programmes of State Governments. Several such technologies validated by official technical agencies are now available and need to be scaled up in use.”
Prefabrication often referred as Prefab, it is the technique of preparing the building parts/structures in a factory or a production site other than its actual location, after hardening the building components, it is later transported or shipped to site where actual construction is taking place. Prefabrication construction technologies complete in two stages, first manufacturing of building components away from the actual site and second erection of these components on the building.
Preparation of building components in manufacturing unit is better than conventional procedure, as Prefabrication method could give a better design for the building parts and undergo with quality controlled manufacturing processes. The best part of this technique is, it allows work to continue despite bad weather conditions.
Prefabricated technology tackles the challenges of time taken for construction, lack of raw material in rural areas, lack of work force or lack of trained workers. In this process, building components prepared under the supervision of trained engineers and scientifically planned architecture methods are adopted during the process.
Large construction companies mostly preferred prefab materials for commercial structures, yet it is not common in India. However, this technology has been used in big infrastructure projects in India, like metro rail projects, elevated expressways and other.
The advantages of adopting Prefabricated technologies are, saving in cost, material and time, speeding project works, building parts produced in close supervision, work not affected by bad weather condition, work safety and high comfort level, computerization of production process, quality controlled etc.
Mr. Naidu further said, the government is taking several measures to popularize these technologies. These technologies are now being used in big housing projects and need to be adopted for individual and small scale housing projects. With increase in demand, prefabricated construction technologies would become even more cost effective and they need to be promoted in a big way.
Dr. Nandita Chatterjee, Secretary of HUPA informed that Ministry of HUPA is in talks with the Ministry of Defence for building two lakh houses with alternative technologies for Paramilitary forces. She also said that construction of 37,500 such houses is being planned in Mumbai after a successful pilot project of 200 houses. Demonstration projects have been executed in different zones of the country and several States like Andhra Pradesh, Telangana, Karnataka, Odisha, Bihar, Jharkhand, Haryana and Maharashtra have shown keen interest in alternative construction technologies.
While speaking to media, Chairman and Managing Director of Hindustan Prefab Limited Mr. Rajesh Goyal said, “prefabricated technologies are as good as conventional technologies in terms of strength and durability and even better in several respects like quality and finish, speed of construction and would be more cost effective when production increases.”
Minister of State for HUPA Mr. Rao Inderjit Singh also urged government departments like Defence, Railways and PSU to promote such technologies in a big way.
