An engineered foundation serves as the critical interface between a superstructure and the supporting earth. Its primary function is to safely transfer the cumulative loads of the entire built structure to a stable stratum of soil or bedrock. Foundation design must account for anticipated soil variability, load distribution, and potential subsurface movements, such as settling or differential movement. Foundation types are generally classified into shallow foundations, which distribute loads over a relatively wide area near the surface, and deep foundations, which utilize elements like piles or caissons to transfer loads to stronger, deeper layers. The selection and engineering of the appropriate foundation system are vital to ensuring the structural integrity, service life, and stability of the entire construction.
