Hello Sir

The Rates seem reasonable, what about cost for getting electrical connection, sewage connection
Plan approval by BBMP, and then gate subdekal and plumblines for solar .

Secondly number of electrical points, wardrobe and showcase .

The number of bathrooms ad no of wash basins also need to specified.

My contractor charged me extra for drop mesh , parapet wall as extra

Hello Sir,
Thanks for replying, Contractor dint bare the cost of BBMP approval. we ourself have done it.
Sewage-- they only provide the connection upto compound wall the rest is ours.
About electrical connection they will get only TP from bescom, the bill has to be paid by us. and we have to apply for permanent connection after completion
We havent spoken about the solar plumbline., I have to clarify about that(thns for mentioning it)
Wardrob and showcase are not in the scope of contract.
Contractor say the things which are not in the list are of extra cost.

The thing which surprised me is he is charging extra for -Flagging concrete alround the plinth. ,Sump tank of any capacity. and Rain water harvesting. is this the trend going around in the market today?

Please note the following
Assuming lets say a house has to cost 2500000/- at a given rate per sq ft, the contractor shows a lesser price for the materials in the total budgeting. For eg we were also given 45 Rs for vitrified but in reality any good branded quality vitrified will not come less than 70 to 85 Rs per sft which is nearly double the estimate. Same is the case with ceramic tiles for bathrooms.When you come to the finishing stage you will have require another 5 lacs because all the good sanitary, tiling and other materials are costing more than the estimate given by contractor
Bricks they will try to put of lesser quality , when you intervene the higher quality will cost more.All this pushes up your total cost by another 5 to six lacs.
Knowing this the contarctor apportions more in labour and makes a killing .Pls take stage wise cost estimate eg foundation, ground, wood work, sanitary, electrical and a break up of these into material and labour . Then check up the material costs personally to find whether the estimate tallies with reality and work out actual cost based on square feet and add up all the materials and all labour to get to thumb rule percentages and check.
Also the contractor takes you to shops where he has a commission worked out so that anything you buy is already inflated and he gets a cut .Make it clear at the beggining that you will decide on materials .you will get quality at the right price if not at a cheaper price.
