Overview of the Article

The article examines the review support system, powered by an industry-specific AI agent, that Bureau Veritas Japan and mign have been using in live building confirmation and inspection work since 2026. It approaches the topic from two angles: the practical perspective of the building inspectors who use the system day to day, and the technical perspective of mign, which developed it.

On the practical side, the article shares what the system has delivered in real-world use — for example, verifying use restrictions under Article 48 of the Building Standards Act, and flagging a calculation error in supporting documents while also suggesting its likely cause. It is equally candid about the areas where today's AI still struggles, particularly in interpreting visual information: misreading figures on drawings, or failing to distinguish solid lines from dashed ones. On the technical side, it explains the difference between a standalone generative AI model and an industry-specific AI agent, and walks through how the system works — from reading the application documents to identifying the applicable regulations, making determinations and presenting the supporting rationale, all feeding into the inspector's final judgment. The article closes with a look ahead at how much decision-making can reasonably be entrusted to AI, and how the role of the reviewer is likely to evolve as AI becomes part of the process.
