MCD3 Co., Ltd. (Shibuya-ku, Tokyo; President: Masao Iida; hereinafter 'the Company') will begin offering 'Green Site AI Check (tentative name)'*2, a new feature that significantly streamlines document checking operations using AI technology in 'Green Site,' a labor and safety document creation and management service for the construction industry, during fiscal 2026. Prior to general availability, Taisei Corporation (Shinjuku-ku, Tokyo; President: Yoshiro Aikawa; hereinafter 'Taisei Corporation') will begin early use of the feature in April 2026.
## Background of Development
While the construction industry has been improving operational efficiency through the digitalization of labor and safety document (commonly known as Green Files) creation and management using Green Site, the task of prime contractor representatives checking documents submitted by subcontractors for errors and missing attachments one by one and requesting corrections remains a significant burden. This document checking operation requires a tremendous amount of time and effort, and incurs costs when outsourcing to external BPO*3 service providers, presenting a major challenge in terms of productivity and cost.
Therefore, the Company initiated the development of this feature to solve this issue by fully utilizing its advanced AI technology.
## Overview of 'Green Site AI Check'
'Green Site AI Check' is a feature where AI automatically checks documents submitted by subcontractors using Green Site. It verifies the presence of attached documents such as purchase orders and acceptance letters, checks the content written in those documents, and automatically sends correction request emails if there are any deficiencies.
## Expected Effects
We estimate that the introduction of this feature can reduce the total time spent by prime contractors on document checking operations by up to 85%. This will allow prime contractor representatives to focus on more value-added tasks. Additionally, if there are deficiencies in submitted documents, subcontractors can receive feedback as early as the next day, enabling prompt corrective actions.
## Early Use by Taisei Corporation
Taisei Corporation will use this feature in advance starting April 2026 to verify its effectiveness. We will strive for further quality improvement while receiving feedback from their verification process.
### Comment from Mr. Koji Nakatani, General Manager of DX Promotion Department, Building Construction Division, Taisei Corporation
'We introduced Green Site in 2005 and have been working to improve the accuracy of construction system ledgers and reduce the administrative burden on both subcontractors and our employees. On the other hand, the task of checking and correcting submitted documents still relies heavily on manual labor, making further productivity improvement a challenge.
Receiving a proposal for a new AI-powered solution from MCD3 Co., Ltd., we expected it to contribute to solving these challenges and decided to cooperate in its early use. Through this initiative, by combining their advanced AI technology with the knowledge and know-how we have cultivated at construction sites, we aim to achieve both streamlined document operations and quality assurance.
Furthermore, we hope that this feature will promote the sophistication and standardization of business processes throughout the construction industry, contributing to industry-wide productivity improvement and work-style reform.'
## Future Outlook
We will continue to utilize AI and digital technologies in services such as 'Green Site' to contribute to productivity improvements and work-style reforms at construction sites. Under our mission of 'Staying close to industry and continuing to face social issues,' we will strongly promote DX across the entire construction industry.
