It is necessary to plan of Rs 1.32 crores to complete the research meticulously all the details related to the work and bring it to a stage of technology design and construction, especially issues Structural design manual transfer. related to optimal use of the GFRG panels, recently published by BMTPC The panels may be unfilled, partially filled or concrete and reinforcement, as well as issues (cover page) fully filled with reinforced concrete, as per the related to transportation, erection, provision structural requirement. Experimental studies of services and deployment of manpower and and research have shown that GFRG panels, equipment. Ideally, plants manufacturing suitably filled with reinforced concrete, GFRG panels need to be set up in many possess substantial strength to act not only regions, to minimize transportation costs, as load-bearing elements, but also as shear and to cater to the immense and urgent walls, capable of resisting lateral loads due to need for mass housing in India – for which earthquake and wind.

It is a model housing apartment, combining four flats (two for the Economically Weaker Section and two for the Lower Income Group), which can be replicated for mass housing, vertically and horizontally. It is also planned to demonstrate the completion of the entire superstructure and render it fit for occupation, within 30 days after the laying of the foundation. The use of prefabricated light weight (43 kg/m2) GFRG panels for the entire building system implies not only faster construction time, but also reduced labour and safer working environment. Also, the cost of completed construction with all amenities is reduced to around Rs. 1250 per sq. foot.In an effort to test this technology and its durability, the team at During the construction of the demonstration building, we also conducted a short-term IITM will conduct a series of experiments, course to train 35 engineers on the design and construction aspects of GFRG building including filling the roof with water. systems
