[The Technical Committee of Foundations]

○ Purpose of establishment

  “Foundation is no better than its supporting soil, the structure no better than its foundation”: this phrase emphasizes the role of foundation engineering in which the upper structures can only function properly when the foundations are strong. Foundation systems should be economical while achieving structural stability and serviceability in various load cases and underground conditions. Research and development in foundation engineering are critical to face challenging construction sites such as deep soft ground, deep marine sediments, and extensive underground excavation, which are normally avoided due to technical and economical issues. Furthermore, diverse applications in civil engineering involve new researches that can provide new, safe, and economical techniques for mega foundations such as skyscrapers, offshore foundations such as bucket foundations and floating foundations for wind turbine and platforms, and foundation reinforcements of improving old structures.

○ Main topics

The technical committee for foundation engineering periodically helps the civil engineering society by holding committee meetings and academic seminars to share state-of-art advancements and research outputs in the field of foundations. In addition, the technical committee aims to contribute to the civil engineering industry by sharing case studies of practical applications at construction sites and foundation-related technical works.
