Recommended depth for excavation

[tendlu]

I sort of know this depends on soil testing, but would like to know:

what is the recommended depth for excavation assuming the soil is good in a site? or what should be the minimum depth for excavation for a good soil?

Hi Tendlu,

5 feet or 1.5 mtrs

thanks Ravi.

What is the standard width for excavation? I should have probably asked it before, but just realized i need to know this as well for calculation

Hi Tendlu,

generic is 5 ft X 5ft X 5ft (Length X Breadth X Depth).

Hi tendlu
Footing depth is generally 5' considering that we get a hard soil at that deep.So footing depth is always based on hard surface and ht of the building (once it goes beyond 4 -5 floors).
Footing size is based on the load factors on that specific column.If the loads are uniform on all the sides then the footing size is uniform all the sides of column say 5'x5' ,6'x6' etc.
Some times the columns are eccentric and u need a special footing design for it.

Ravi/Praveen,

When you say the excavation depth should be a minimum of 5', are we talking about the excavation for the column or the excavation depth for stone masonry (SSM - where the load bearing walls come) is done? If 5' is the minimum depth for column excavation, what is the standard excavation for stone masonry (SSM) - both depth & width?
