Nakano Fudoh Construction to Expand Use of "Kensetsu Site Series"

MCD Three Inc. (Shibuya-ku, Tokyo, President and CEO: Masao Iida) announces that Nakano Fudoh Construction Co., Ltd. (Head Office: Chiyoda-ku, Tokyo, President and CEO: Takashi Iizuka) will unify its site information infrastructure with the cloud service for the construction industry, "Kensetsu Site Series," to fully promote productivity improvement, work style reform, and technology transfer.

In addition to "Green Site," which is used as the core of labor and safety management, Nakano Fudoh Construction will newly introduce "Work Site," a site construction management service, and "Skill Map Site," a service for managing proprietary qualifications, with a pilot operation planned to begin at some sites from fiscal year 2026, followed by a gradual company-wide rollout.

Background for Expanded Adoption: Towards Building a Sustainable Site Environment

The construction industry faces urgent challenges such as a shortage of workers due to the declining birthrate and aging population, and the need to comply with the overtime work hour limits (Note 1) that came into effect in April 2024. Nakano Fudoh Construction believes that improving site productivity, creating a better working environment, and ensuring smooth technology transfer from experienced workers to younger ones are essential for continued sustainable growth and the delivery of high-quality buildings.

While the company has been advancing the digitalization of its operations, it faced challenges with fragmented information due to the concurrent use of multiple systems, leading to complex site management tasks and administrative work for subcontractors. To fundamentally solve the problem of information fragmentation and create "sites where employees can work comfortably and grow together with subcontractors," the decision was made to unify the information infrastructure with the Kensetsu Site Series, which has a proven track record of adoption by many subcontractors.

Adopted Solutions and Expected Effects

1. Work Site: Promoting Work Style Reform and Improving Productivity This service digitizes and automates routine tasks such as daily safety log creation and labor hour aggregation. It reduces the time site employees spend on document creation, freeing them up to focus on higher-value tasks such as quality control, technical guidance for younger staff, and close communication with subcontractors.

2. Skill Map Site: Promoting Proprietary Certification Systems and Strengthening Partnerships In conjunction with Nakano Fudoh Construction's "Excellent Foreman System" (Note 2), this service visualizes the proprietary qualifications and site experience of foremen from subcontractors in digital data. This enables appropriate treatment based on objective evaluations and planned training support, contributing to increased foreman motivation and the building of strong partnerships with subcontractors.

Key Points for Selecting the "Kensetsu Site Series"

Among the many services available in the construction DX market, Nakano Fudoh Construction decided to expand its use of the Kensetsu Site Series as its "DX platform for construction sites" for the following three main reasons:

A "Common Language" Widely Adopted by Subcontractors The fact that many subcontractors already use Green Site in their daily operations was highly valued, as it minimizes the educational costs and operational learning curve associated with introducing a new system.

Seamless Data Integration Without Fragmentation Site-related data, from labor and safety documents to daily entry/exit records and individual worker skill information, can be centrally managed within the Kensetsu Site Series, including Green Site. This eliminates the need for duplicate data entry and simplifies management.

Future Potential as a Platform Supporting Sustainable Growth The platform's ability to respond quickly to legal revisions and its proactive approach to AI utilization were recognized, highlighting its future potential as a continuously evolving platform.

Future Outlook

Nakano Fudoh Construction plans to begin a pilot implementation at some sites from fiscal year 2026. After establishing operational methods by incorporating feedback from sites and subcontractors, the system will be gradually rolled out to the entire company.

MCD Three will provide comprehensive support from implementation to adoption to ensure this initiative contributes to Nakano Fudoh Construction's goal of "building a sustainable site environment" and to enhance the overall appeal of the construction industry.
