G) What is minimum Dia of Bored pile ??

Question

Accepted Answer

The minimum diameter of a bored pile depends on various factors such as soil conditions, load requirements, and construction methods.

The minimum diameter of a bored pile is typically determined by the design engineer based on the load requirements and soil conditions at the site.
In general, larger diameter bored piles are used for higher load-bearing capacities.
The minimum diameter of a bored pile can range from 300mm to 1200mm or more.
For example, in soft soil conditions, a minimum diameter of 600mm may be required to ensure stability and prevent excessive settlement.
On the other hand, in rock formations, smaller diameter bored piles may be sufficient.
The minimum diameter of a bored pile also depends on the construction method used, such as whether it is drilled using a casing or without a casing.
In some cases, local regulations or project specifications may dictate the minimum diameter of bored piles.
It is important to consider the specific project requirements and consult with a geotechnical engineer to determine the appropriate minimum diameter of bored piles.

Accepted Answer

Boring pile minimum Dia is 450mm as per IS 2911, Part-1 and Section-2.
