Foundation design is a specialized skill in engineering that involves the design and analysis of the foundation or substructure of a building or structure. It is critical to ensure that the foundation is capable of safely supporting the weight of the structure and any applied loads, such as wind or seismic forces. Foundation design requires understanding of soil mechanics, geotechnical engineering, and structural engineering principles. The design process involves site investigation, analysis of soil conditions and loads, selection of foundation type and design, and construction implementation. Proper foundation design is essential for the stability and longevity of any structure.
