Raft Mat Foundation both are same or different?

 

Area 95’x65’ = 6200 Square Feet

Should I go Excavation 5’ or 10’ deep?

What will be the cost of Raft Foundation + 35 Columns of 1.5’x1.5x10’ height (2’ included extra from ground level) + Beams 1.5’x1.5’

Kindly tell me the cost/ Square feet + Labors charges, total cost?

Really, you are providing a great benefit to the society, God bless you

 

Thanks and best regards,

Dear Sir
        The depth of foundation is taken from the bearing capacity of soil/ land. In general the foundation depth should be up to hard strata of soil and minimum 4 feet.The cost of raft foundation and other component can be calculated after the structural design. Because in  the design the thickness of foundation and MS Steel is calculated according to load coming or bear by the foundation irrespective of bearing capacity of soil and taking safety factor and safety from earth quack etc.
In my opinion you should act according to technically as your project is big and take no risk for a small amount of design. If we have proper design than we save the cost by tentative method and with safety in mind.
