Hackathon Overview
The 2nd GeoTechathon was organized as a joint special session of the 3FOMLIG Workshop to explore how agentic AI can advance geotechnical engineering. Its main goal was to foster collaboration across industry and academia in building multi-agent systems that integrate large language models (LLMs) with traditional geotechnical computational tools to address real-world geohazard challenges.
Running from May to October 2025, the event included tutorial sessions in May, an active development period from June to August, a submission phase in September, and final presentations at the 3FOMLIG in October. The organizing committee comprised five academic faculty members from different institutes and a team of supporters—mainly young researchers and students—who provided guidance throughout the hackathon.
Participating teams designed and prototyped AI workflows, presenting their work through five-minute pitches that highlighted creativity and impact. A judging panel composed of six geotechnical and machine learning experts from industry and academia, together with an audience voting system, jointly determined the winners using criteria focused on problem relevance, innovation, accuracy, robustness, and presentation quality.
After the winning team was announced at the special 3FOMLIG session, a panel discussion was held to address audience questions and share perspectives on the future of agentic AI in geotechnical engineering from both industry and academia. The event successfully sparked greater interest in AI applications within geotechnical engineering and attracted many new volunteers for the next GeoTechathon event.
