Pile foundations are habitually used for large structures and in certain situations where the soil at shallow depth is unsuitable to withstand excessive settlement & resist uplift.

Thank You.

Factors affecting the selection of foundation:

Factors affecting the selection of foundation based on politics to basic criteria:

1. Based on soil condition
2. Based on loads from the building

1. based on soil condition:

• The shallow foundations are most preferred Foundation whenever the soil close to the surface which is capable of support structural loads.
• Where ground close to the surface is not capable of supporting structural loads Din hard starter is used for the foundation is required.
• The stable ground requires Shallow Foundation whereas filled up Grounds has low bearing capacity thus requires deep Foundation.

2. based on loads from the building:

• In case of very low height building in a larger area than the extent of loading is relatively very slow and that’s why Shallow Foundation con resists the load from the structures.
• In the case of high rise building with less area and high amount of loads. In that case, the foundation is required. Because the shallow Foundation may not be able to resist such high loads of great intensity.

Thank you.
