Pre Fabriated structures and how they can benefit the building industry has been a hot topic for quite awhile and many employers expect even a fresher to have an opinion on this; which is why we have included this in the resources of Gallopper. Our intention at all time is to ensure the Job Seeker’s betterment and confidence in facing job interviews. So here goes:
Construction methods across India have remained more or less the same over the last several decades. This only brings in huge inefficiencies at every level of the construction phase leading to huge costs.
Finally in the recent past, alternative construction technologies such as prefab structures are slowly gaining acceptance in the Indian housing market. With the rapidly increasing population and need for truly affordable housing options; there is a huge need for architects and construction companies to develop new technologies that can provide the same look and feel of traditional housing (made up of cement brick and mortar) but can be constructed in lesser time and offer cost effectiveness to developers.
Prefab structures constructed from factory-made components that are assembled on site by simply being bolted together as per manufacturer’s specifications, is one such method which is finally getting acceptane in certain circles. Only the foundation is made on site and finishing such as plumbing, electricity cables, are done once the structure is completely erected on site.
Plaswall, sandwich panels, polyurethane composite panel system are some of the technologies available in the market and claim to be an alternative to traditional housing system. Developers are now experimenting with these technologies in their affordable housing projects. The primary cost benefits of prefab structures are derived from the speed of construction and the optimization of raw materials.
Integrated engineering design and detailing make it possible for prefab structures to be erected at a fraction of the time that it would take a conventional building to be erected. The time savings contribute to lower interest costs during construction and thereby leads to commencing commercial activities far earlier. The optimization of raw materials has the effect of reducing material cost of the building. Lowering the weight of the structures brings about significant savings in the foundation cost.
Although prefab structures offer a lot of advantages to developers but still there are stumbling blocks in the path of their success in India. There is a notion that prefab structures limit the design choices as there is lack of flexibility in on-site design changes. The biggest myth is that the quality it offers after construction and subsequently acceptability to Indian consumers.
Though prefab structures are successful in the developed world, the technology is still in its nascent stages in the Indian market. As demand for low-cost housing and affordable housing in India grows this technology will undoubtedly find more takers.
