The Chicken Claw Foundation: A Revolutionary Innovation by Prof. Dr. Ir. Sedyatmo

Denpasar – The Chicken Claw Foundation, a groundbreaking innovation in civil engineering, was invented by Prof. Dr. Ir. Sedyatmo in 1961. This revolutionary design arose from the need for a strong and efficient foundation on low-bearing soils, such as soft or marshy ground. The concept not only offered a practical solution but also became a monumental achievement in the development of construction technology in Indonesia.

The foundation’s design integrates a thick concrete slab connected to hollow concrete pipes embedded in the ground. This structure resembles a chicken’s claw, where the pipes act as claws gripping the soil, providing enhanced stability for structures built upon it. The design enables even load distribution, making it ideal for supporting large-scale structures such as highways, airports, and skyscrapers.

One of its earliest applications was in the construction of Kemayoran Airport in Jakarta. Its success demonstrated the effectiveness of this method in addressing challenges posed by soft soils. Since then, the technology has been widely adopted in major projects both in Indonesia and internationally, including toll roads, ports, and high-rise buildings.

Advantages of the Chicken Claw Foundation

• Cost Efficiency: Reduces the need for extensive soil excavation and additional materials.
• Adaptability to Soft Soils: Provides stability without requiring prior soil reinforcement.
• Strength and Durability: Capable of supporting heavy loads over long periods.

This invention not only brought prestige to Indonesia but also established Prof. Dr. Ir. Sedyatmo as a respected figure in civil engineering. The Chicken Claw Foundation has gained international recognition and remains an innovative solution to modern construction challenges.

Through his significant contributions to construction technology, this foundation stands as a testament to how local innovations can create global impact. Prof. Dr. Ir. Sedyatmo’s legacy continues to enrich scientific knowledge while providing tangible benefits for national development.
