Post RERA New Techniques Help Builders Complete Project on Time
Post RERA New Techniques Help Builders Complete Project on Time. Technology is creating its space in the real estate owing to the new norms of the Real Estate (Regulation and Development) Act. The need to complete work within the stipulated deadlines has increased the demand of time-saving technology amongst developers.
Among the techniques being adopted are 3D modeling, aluminium formworks, tunnel formworks and jump forms. Post RERA New Techniques Help Builders Complete Project on Time. These technologies not only shrink the time taken per unit or floor but also help create sturdier homes streamlining the design-to-construction process.
Deben Moza, executive director of project management services at real-estate consultancy Knight Frank India said that the use of such technology is slowly growing across the industry.
Aluminium formwork, a technique where the metal is used in place of the traditional plywood shuttering when making the mould or framework for the construction of the outer walls, floors, and ceilings. Aluminium is sturdier, easier to use and provides better finish, especially for the exterior walls. In tunnel formwork, beams, walls and columns are all constructed in one go.
Farshid Cooper, director of Spenta Corporation developers said that a floor takes even less time than with alu-form, and can be completed in about a day.
Both alu-form and tunnel form are more cost-effective if used on several identical buildings, as in a township or buildings more than 20 storeys high. Jump formwork is best used for buildings more than 50 storeys.
Hetal Joshi, Executive Director of projects at Radius Developers said that in a high rise, the core of the buildings, which includes areas like the staircase, lift and lobby, takes longer to build than the floor plan of flats. She added that jump form helps build the core of two or three floors at once, speeding up the construction process.
Shruti Choudhari, deputy director at BL Kashyap and Sons, a construction company said that the upgraded tech used also requires less manual labour. Rohit Poddar, managing director of Poddar Housing and Development said that there are reduced chances of leakage and cracks as the core is metal and cement and the brickwork is minimized.
Tech is entering the process even before construction begins, though. 3D modeling is playing a major role in streamlining operations. Deepak Dhar, director of project management at real-estate consultancy Colliers International India said that they are seeing builders take to technology more. Building Information Modelling, in particular has played a major role in making planning easier.
BIMs are 3D modeling systems that allow developers to design even functional characteristics like plumbing and electrical wiring before they begin work. This means they can make minor tweaks, work out glitches and even manage inventory and manpower more efficiently.
The major drawback is the rise in cost. Cooper said that the key reason developers have preferred to stick to traditional methods is cost. The new approaches can cost 15% to 25% more.
Ms. Joshi explained that it is only in the larger projects that the cost can be offset by the time saved. The gap has to be vast enough. Using this kind of technology is most beneficial when used in repetition.
Using aluminum formwork or tunnel formwork also requires a higher grade of concrete, for similar results, which may not be easily available or may raise costs further. Read more
