yes I got professional support!
The SE said 12mm is enough for 1st floor columns and beams coz the ground floor walls are 9" thick as he said 12mm enough to bare the weight of second slab as well. i have a roof top in my house. but i have seen some people are using 16mm
now i have doubts..

It depends machan. In my design I don't have enough walls in the middle of the house. I preferred the house to be having less walls. So my Engineer used 18 x 9 beams and 16 mm tor steel to bear the load of the slab. If you have enough walls to support the slab beams, I don't see a fault in using 12 mm tor steel.

By the way I had to bring the Engineer several times to the site to explain the mason how the tor to be tied and connected with others. Actually those designs are too much complicated for a ordinary mason to understand.

Anyway due to continuous reference of those drawings, now I can read and suggest the best method even without the Engineer. LOL

I was wondering why were you having such strong beams. I had the same sort of scenario

Well, column spacing

 

[dilshan87]

Really good work. That's how well planned persons.
My father too has all details... Thart was by mid nineteen eighties...

please add following details too...
column sizes, how many floors, square foot area of house too...
easy for comparison

Not a problem machan. By the way I don't want to disclose my drawings of the house to the public. But I can give those details for sure.

I maintain a Access Database for material purchases and labour payments. I raise a 3 ply voucher every time before I pay any advance to the masons. I copy is given to the mason, others are filed.

I am doing the QS role myself. I am somewhat skilled in my mathematical knowledge and I measure the work done using my drawings' heights, length's and widths. Then I multiply it with their rates and pay them only for the work done. (I deduct all the duplication and get the exact work they have done)

Colomns & Foundation

• 12 mm Tor used Columns were laid on 3 x 3 ft footings which were excavated upto 5 feet, compacted by poker with quarry dust

• 16 mm Tor used Columns were laid on 4 x 4 ft footings which were excavated upto 5 feet, compacted by poker with quarry dust
• Footings were laid upon 2 inch screed concrete and connected with rubble foundation upto 2 ft. Upon Rubble, all were tied with a 9x9 plinth beam usin 12 mm Tor.

My house is a two storied one with a 2nd floor terrace. Height goes upto 39 feet with the water tank.

Total Sqft of the house is 2965 sqft with balconies and terrace.

That's a quite difficult question to answer. The answer depends on loads of factors but if you insist to give a number I would go for 6 months.
