As the labor shortage in the construction industry deepens, Arent has implemented the PROCOLLA AI construction schedule management tool at 鍜治田工務店. AI trained on historical data creates draft construction plans, with the aim of reducing reliance on individual expertise.
In the construction industry, challenges related to overtime-work regulations following the 2024 problem and the transfer of expertise as skilled technicians retire have intensified, accelerating productivity improvements through digital transformation. Competitors are advancing initiatives such as ANDPAD's platform development and Photoruction's AI drawing analysis, and AX (AI transformation) is spreading. Arent advocates the democratization of tacit knowledge and is strengthening its presence in digital transformation support for the construction and plant industries. In the fiscal year ended June 2026, it achieved revenue of ¥5.83 billion, up 44.7% year on year.
PROCOLLA, implemented this time, is a SaaS-based tool jointly developed by Obayashi Corporation and Arent. Its AI, trained on historical construction schedule data, creates a draft plan. The operating model, in which people make fine adjustments, is being tested, with the aim of verbalizing the criteria used to make schedule-planning decisions and reducing reliance on individual expertise. Information can be shared in the cloud, creating an environment in which relevant parties can access the latest schedule information.
Going forward, the company plans to test applications in estimating, payment management, and progress-based billing by combining schedule information with amounts and responsible departments. 鍜治田工務店 has a history of more than 100 years and expects to improve operational efficiency through system integration, including the establishment of a BIM Strategy Department and integration with 構造ソフト, which provides 現場ナビ工程. Standardizing AI-based schedule management may also contribute to the digitization of knowledge transfer.
