Now for the cost of some raw materials with some learnings:
20 MM Jelly stones - Rs.20.50 per cft for a truck of 540 cft.
Sand from TN ---> 25000. (This is where they fool people, stating that there is 6 units of sand. The dimensions of the vehicle (Tipper) is usually 16 x 7.7 x 4.5, and it is not possible to have 600 cft sand in it, and the sand owners insist on it. Always inform the Sand guys that you will pay after you measure the volume. Usually it should not exceed 540 cft max wrt a Tipper).
Labour cost for concrete mixing (14 pillars and Sump) 8600. (I think you can further negotiate the price here, can come down to 6500; as the work was done by 10 people, and the person in charge informed me a day earlier that there will be 15 workers and fixed the price for 8000 + 600 for food. But the next day he got the job done by 10 workers only).

Cost of Size stone for Building foundation: 10 rupees per stone. They do not count the stones, and 1 truck load might contain around 850 to 950 stones and they expect 9000 rupees as payment.

Hi,

I'm planning to start house construction (30'x40' G+1) nearby mahadevapura. Please let me know the marginal difference between brick wall and solid blocks (6').

Approximated build-area will (850 Sq.ft + 1000 Sq.ft).

Thanks in Advance,
Pradeep

I am doing a construction right now with similar specs as yours. One thing I felt is, go for 9" walls instead of 6" ones. Contractor/architect insisted on 6" apco block walls with 6" pillars / beams and I went for it. But the problem am facing now is , 6" is too small a width for pillars/beams. Too small in the sense that, if you dont have outstanding quality of work during centring/shuttering , this beams/pillars wont be aligned for the steel structure contained within it. Meaning, the steel roads wont be perfect center to the mould you make to cast the beams and pillars, effectively they are either misaligned inside or slightly seen on the exterior of the pillars/beams.

I believe, 6" apco blocks / 9"pillars is possible, but that makes the pillar/beams to protrude either inside or outside to your house. So overall, I would suggest either 9" cement blocks with 9" pillars ( costly) or good mud bricks( which is 9" and probably SCB brand or something which I heard is good) with 9" pillars. This way , though you may loose some 3" on each wall ( interior space) , I feel , its still worth it. Because, you dont get that kind of perfect laborers here and its a pain to see steel rods seen from outside, on your pillars/beams. Also , as I understand( probably am wrong here), the honey combing will be more where there is more of reinforcement ( basically your 6" pillars/beams get cramped with steel structure in it where as it will be less for a 9" width).

hi jackalbda,

Very thanks. With your reply , I can understand the problem associated with 6" wall. Even my architect asked me to go for 6" wall to save more space. I will go either with 9" brick or 9" Blocks.

Thanks,
Pradeep

Also for walls where plumbing lines are running, ensure they are 9" or 10" thick. Water pipe vibrates during water flow (due to air inside pipe) which causes cracks on wall if wall is too thin

I am planning to construct a basement (around 4-6 ft below ground and rest above the ground level) for my house I had a couple of questions:

1. I read replies from Praveen and few others that the cost would be higher. Is there any estimate on how much the cost would be higher in terms of % cost. 10%, 20%, 30%?
2. If there are no constructed buildings around my site (left, right, back), is there any additional requirements for construction of basement? I am specifically worried about heavy rains that flooded basements of apartments couple of years back.

Thanks,
GD.

Hi
I have one query, If we make good structural design, and plinth beam design, do we need to lay stone foundation below plinth beam?
