What CM Engineering does

CM Engineering (株式会社シーエム・エンジニアリング) is a Japanese privately-held construction administration support firm headquartered in Hiroshima, serving primarily the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) Chugoku Regional Development Bureau across all five Chugoku-region prefectures (Hiroshima, Okayama, Yamaguchi, Tottori, Shimane). Founded on September 2, 2013, with ¥50,000,000 in registered capital, the company was established to take over the government client-support and public infrastructure management support operations from the General Incorporated Association Chugoku Construction Promotion Association — a transfer completed October 1, 2013 that established CM Engineering as the de facto primary contracted service provider for MLIT in the region.

The company operates four service lines: 発注者支援事業 (Client Support Services) covering technical review, quantity surveying, and construction supervision; 公物管理補助事業 (Public Infrastructure Management) covering river/dam/road patrol, levee/gate management, and special-vehicle permit support; 建設マネジメント事業 (Construction Management) covering public-project monitoring; and drone-based survey services. Technology is concentrated in construction-consultant-grade civil engineering workflows and a proprietary cellular-drone capability developed with NTT Docomo (joint demonstration March 2019), enabling LTE-connected flight beyond visual line of sight with real-time multi-site video streaming for disaster response under a 2014 basic agreement with MLIT.

The business model is B2B professional services revenue, with all services delivered through individually negotiated government procurement contracts won via competitive bidding. The company has 510 employees as of April 1, 2026, including 185 first-class civil engineering management engineers, 9 Professional Engineers, 55 Professional Engineer Assistants, and 76 second-class unmanned aircraft pilots — a credential density that constitutes the primary barrier to entry. CM Engineering is not publicly listed, has no disclosed parent, no subsidiaries, and no external funding rounds; ownership information is not publicly available. The current Representative Director is Koori Ikuo (小尻 郁男).
