I had heard a lot about the HT wires in the project. In order to check the authenticity, I visited the property myself and saw that there is a high tension line with 5 towers within the complex – goes by the eastern and northern sides. There is going to be a gap of 30-60 feet between the high tension line and the building, the distance varies from block to block. Propsurf
I have read an article about Service Tax and VAT recently so though of sharing the link with you. Have a look and I hope this will help you to some extent http://www.quikr.com/homes/blog/know-all-about-service-tax-and-vat+76
As far as I know, Service Tax is Calculated 12.3% of the 40% Portion of the Total Cost and Vat is 5% on Total Value. I would suggest you to cross check once with a legal expert.
