Monolith Group Promotes "Waste Reduction" to Solve the Four Key Issues in the Construction Industry Safe operation of multinational personnel and shared use of machinery to be phased in from September 2025

Monolith Group (Monolith Corporation: Fuchinobe, Chuo-ku, Sagamihara-shi, Kanagawa; President: Tsuyoshi Kawamura / Kawamura Kogyo: Shimo-Oyamada-cho, Machida-shi, Tokyo; President: Atsushi Kawamura) will gradually introduce, starting in September 2025, the "fourfold challenge" facing the construction industry: labor shortage, heat wave, maximum overtime work, and minimum wage increase. In September 2025, the company will begin phased introduction of a multinational workforce that places the highest priority on safety communication in Japanese, and shared use of machinery with the greatest benefit of reducing the investment burden.

In response to this challenge, we have shifted our thinking from labor saving to "waste reduction. We will bear the initial investment, maximize the machine utilization rate, and promote the creation of workplaces that "free craftsmen from long working hours and give time back to people.

Multinational human resources

■Not manpower saving, but waste saving

The Monolith Group will work to ensure stable productivity even in extremely hot weather and under the restrictions of overtime limits by promoting "waste reduction" to eliminate friction in work, rather than "manpower reduction" to reduce the number of workers, starting with the reduction of waste such as "waiting, searching, rework, reworking, and duplication" that occur in the workplace.

■Safe Operation Assurance

In order to reduce the risk of rework and accidents caused by discrepancies in communication among multinational personnel, we will implement thorough finger pointing and calling, and regularize the training and evaluation cycle.

Shared Use of Machinery (Sharing)

Through shared use (sharing) of machinery, we aim to equalize utilization rates and prevent equipment from becoming idle. MHI will bear the initial investment, and participating companies will share the operating costs, thereby lowering the entry barrier to mechanization and increasing the speed of introduction. This initiative will be introduced in phases starting in September 2025, with the target models and areas to be covered to be expanded sequentially based on the verification of effectiveness.
