Hello,

Is pedestal always required for a column? If so, what is the pedestal for?

I am asking the above because the structural drawing from a structural engineer does not have a pedestal and upon asking he says it is not required for a small construction. So trying to validate the claim and convince him

Now I don't know the technical details, but what I do know is it helps improve load capacity. Most of the house construction in Bangalore do not have pedestal.
If you are building more than 3 stories you can decide to go for it, I don't think it will increase the cost too much, just additional concrete and steel. These kind of work once done you cannot go back and change.
I have it for my home

I second what maheshv said. Though i am currently constructing G+1, i asked my Structural Engineer to design for G+3 and he has pedestals in the design he gave me.

thanks for the input.

my engineer along with the structural engineer insists that a pedestal is not required -- in exact words -- it is just a waste of money for a G+2 or even a G+3 construction. upon insistence, the suggestion is to a pedestal of 15"x21" up to the plinth beam (footing is 6'x6' and column is 9"x15").

Now I have two questions:

a) Can a pedestal go until the plinth level -- i haven't seen a drawing where the pedestal goes until plinth?
b) If the outer wall is 9" and the pedestal (15"x21") goes until plinth level, how would it align? I mean when the column is 9"x15" then it kind of aligns with a 9" outer wall. But with a pedestal of 15"x21" going until plinth and outer wall is 9", i am not sure how this aligns.

Can someone please clarify on this?

Pedestal does not go till plinth beam, it stops at the height of 2 to 3 ft from footing, after that column raises up to plinth beam.

Typical footing cross-section is enclosed for understanding. this may be helpful.
