A rising urban population combined with a resulting shortage of housing has set in place a paradigm shift in the way urban planners, architects and developers are currently visualizing living spaces globally.
In the Indian sub-continent, the migration of mass populations from rural to urban areas is bound to continue. With the population growing faster than expected, it becomes extremely crucial to bring in innovation for streamlining processes in the construction industry that relies heavily on manual work. A great technological break through that has begun to find high uptake in recent years is offsite and modular construction.
Prefabricated construction,as it is technically known, involves manufacturing building’s structures away from its ultimate location. These units – homes, apartments or offices –are built in a factory and transported,usually fully-built, to the building site,where they are assembled using acrane. Experts believe these ‘pods’ area unique mechanism that save time and money, while offering big cities a sustainable path forward.
In traditional construction, a contractor inspects projects through-various subcontractors – who are affiliated with separate entities and work to their own schedules.Moreover, weather can cause delay sand so can a number of unforeseen factors such as awaiting government approvals. In a factory, however, all the skilled workers – from plumber sand carpenters to the electricians– are attached to the factory, and all the pieces are manufactured simultaneously.
Besides speed and cost reduction,the manufacturer possesses records of exactly what quantity of material is needed for a given job. The information helps in generating far less waste than is produced in on-site construction.Furthermore, since modular homes are built in a factory, the materials are stored indoors in a controlled environment, eliminating the risk of mildew, rust, and sun damage that can often lead to human respiratory problems. All these factors make modular construction one of the most environment-friendly processes for sustainable development.
The cost incentive
With cities growing fast,the construction of houses and commercial buildings using pre castor prefab-concrete components made in factories offers significant convenience. A 15-floor structure that can normally take up to 18 months can be completed in 12 months or less.Also, with factory-made components,there is relatively greater assurance of timely delivery and better quality-control. Time saving is cost saving for the seller and the buyer.
A major advantage of the shorter construction time-span is that it allows developers to move quickly to factor in market demand. A developer using modular construction will have a finished product available for rent or sale way ahead of competitors using on site construction. When you consider some of the real-time and significant benefits, in terms of shorter schedules,lower costs and less waste, it just makes good bottom-line business sense to consider modular as the way forward.
Though prefab has become synonymous with economical, the major driver for developers is the enhanced quality. Offsite constructions drawing adequate attention of leading developers given the growing belief that robot-driven mass production actually enhances quality by ensuring that every detail is attended to with factory precision.
Perhaps the best analogy to look at in this context is the motor industry– it is a proven fact that people buy cars from companies that offer holistic solutions, rather than buying a car frame,and getting their seat and engine from somewhere else. The industrial approach to construction activity categorically aims to improve quality.
The prefabrication method of constructing buildings requires diligent and intensive design engineering work beforehand that includes using building information modelling (BIM). However,once this is accomplished, the process becomes much easier. To considers case-in-point – the first elements that include load-bearing structural parts start with a wire mesh being used for reinforcements. It is created by computer to meet exact building dimensions before casts are made.
The process ensures limited scope of error while speeding up the pace of execution and reducing costs significantly. Off-site methods of construction have already been used globally for a number of years,resulting in buildings that are more sustainable, comfortable and with greater longevity.
