General Factors to be considered for Determining Depth of Foundation

General Factors to be considered for Determining Depth of Foundation

1. Load applied from structure to the foundation

2. Bearing capacity of soil

3. Depth of water level below the ground surface

4. Types of soil and depth of layers in case of layered soil

5. Depth of adjacent foundation

The minimum depth of foundation should be considered to ensure that the soil is having the required safe bearing capacity as assumed in the design. However, it is advised to carry out soil investigation before deciding on depth of foundation. Soil investigation report will suggest the foundation depth based on the type of structure, soil properties, depth of water table, and all other variable that should be considered. Soil investigation report provides bearing capacity of soil at different levels and at different locations
