Engineering, Procurement, and Construction (EPC) is one of the most complex and risk‑exposed industries, facing low margins, increasing delivery pressure, and a persistent productivity gap. In this session, MAIRE shares its journey toward AI‑enabled engineering, showing how a structured, multi‑layer digital strategy is being applied across real projects to improve data quality, accelerate onboarding, enhance design efficiency, and reduce execution risks, while preserving robust engineering foundations. The presentation offers a pragmatic, experience‑based view of how AI can create tangible value in large industrial projects.
