I have attached draft floor plan and elevation of the house.

Kindly provide us feed back on the quote give by the contractor, is this reasonable ?

No updates ??

Hi Satish,

1550 per sq/ft sounds quite reasonable with the above mentioned specifications. Please ensure the contractor delivers quality work as per the agreement.

Sagar

Hi,

Thanks Sagar. Yes we will make sure he delivers the same quality.

Satish

Hi Satish,

The estimation is workable because you do not have to spend on foundation. Note that there is Sand Issue in Mysore too.
Also, do have structural engineer if the existing building is old.

Hi Venky,

Thanks for Reply,

The house was constructed 18 months back and was planned for building 3 floors. Yes there is issue of Sand, the contractor has promised T Narsipur Sand. He was the one who constructed the house 18 months back.

Below was my previous post regarding existing buildings footing and column diagram.
