The conventional method is costlier than GFRG. The GFRF can save up to 20 to 30% of overall cost. Regarding Time for G+1, comparing to conventional method which takes approximately 6 months, the GFRG takes only a month. Regarding sustainability, GFRG is eco-friendly where the conventional method is not. When fire resistant is considered, conventional method melts at 1000° Celsius whereas the GFRG withstands 1000° Celsius for hours. Also the conventional method is not prone to earthquakes unless designed separately, but GFRG can resist earthquake; even the panel itself will acts like a shear wall. Regarding cooling effect of the structure, GFRG is cooler up to 4° than the conventional. The life of GFRG is with a guarantee of 80 years where the conventional method lasts for 50 years only. GFRG are water proof compared to usual ones. The carpet area is more in GFRG as the wall thickness is 5’’ compared to conventional one which is of 9’’ thickness which leads to less carpet area! Overall the strength of GFRG is FIVE times stronger than the conventional method.
Other cost factors
There are few more cost factors that need to be considered like approval or permission fee (this is usually a per sq ft charge by the municipality) electricity connection cost,water connection cost and sewage connection charge(This need to be paid to respective govt people),borewell,underground sump,compound wall and gate etc... Interior works like false ceiling and modular kitchen.Construction cost pertain only to the constructed area ,where ever roof is present that is considered as constructed area.
