The Osaka Branch has begun an initiative using generative AI to significantly improve the efficiency of preparing safe work procedures and work visualization diagrams for construction sites. The company announced that drafting time had been reduced from approximately 2.5 days to approximately 2 hours, with nationwide deployment planned.
The Osaka Branch is advancing the use of generative AI to improve the efficiency of site operations. The time required to draft work plans has been reduced from approximately 2.5 days to approximately 2 hours, and the results were introduced as an advanced case at the company’s technical presentation. The company plans to roll out the initiative to business locations nationwide.
For support in preparing safe work procedures, the AI outputs a proposed structure based on the work details entered, reducing drafting time from approximately half a day to approximately 1 hour. This is intended to improve site safety and standardize procedures.
For generating work visualization diagrams, drawings that previously took approximately 16 hours to create in CAD can now be drafted in approximately 1 hour. They are used as visual explanation tools for clients. The AI-generated diagrams depict safety elements at the site in concrete terms, with operational measures also taken to prevent confusion.
A prototype knowledge-transfer system using “Department Manager AI” (tentative name) has also been developed. It aims to enable younger employees to obtain immediate answers to specialized questions through a conversational AI trained on interviews with experienced managers and internal manuals. The quantified impact at the Osaka Branch over one month was estimated at approximately 10 hours saved per user and approximately 1,400 hours saved overall. Nationwide deployment is planned.
