How to select suitable type of foundations?
1. ADEQUATE DEPTH The foundation must have an adequate depth to prevent frost damage. For such foundations as bridge piers, the depth of the foundation must be sufficient to prevent undermining by scour.
2. BEARING CAPACITY FAILURE The foundation must be safe against a bearing capacity failure.
3. SETTLEMENT The foundation must not settle to such an extent that it damages the structure.
4. QUALITY The foundation must be of adequate quality so that it is not subjected to deterioration, such as fromsulfate attack.
5. ADEQUATE STRENGTH The foundation must be designed with sufficient strength that it does not fracture or break apart under the applied superstructure loads. The foundation must also be properly constructed in conformance with the design specifications.
6. ADVERSE SOIL CHANGES The foundation must be able to resist long-term adverse soil changes. An example is expansive soil, which could expand or shrink causing movement of the foundation and damage to the structure.
7. SEISMIC FORCES The foundation must be able to support the structure during an earthquake without excessive settlement or lateral movement.
