Violation

Yugen Kaisha Hosokawa Denko violated the Construction Business Act (Article 28, Paragraph 1) by assigning chief engineers to projects in Echizen Town in 2024 and 2022 without proper compliance. During the 2024 Echizen Town project, the company failed to assign a dedicated technical engineer during the construction period, instead assigning chief engineers to two other projects ordered by Fukui Prefecture, in violation of Article 26, Paragraph 3. Additionally, some of these engineers were also assigned as site agents, which was not permitted for the Echizen Town project, constituting a breach of contract (duty for on-site presence). In the 2022 project, the company assigned a full-time dedicated technical engineer at the office as the chief engineer, which also violated the same legal provisions. The Fukui Prefecture has ordered the company to take measures including promptly informing staff of the violations, implementing training to ensure compliance with relevant laws, and reviewing and strengthening internal management systems. The company’s main office is located at 53-51-1 Sasao, Echizen Town, Nyu District, Fukui Prefecture.

Legal articles

建設業法第２８条第１項

Cause of action

有限会社細川電工は、令和６年度の越前町発注工事において、工事期間中、専任の技術者を配置しなければならないところ、建設業法第２６条第３項に違反して、同時期に福井県が発注する別の２つの工事の主任技術者を配置していたことが判明した。また、これら越前町および福井県発注の工事について、当該技術者が現場代理人としても配置されていたが、このうち越前町発注の工事については、県工事との兼務が認められていないため、契約違反（現場代理人の常駐義務違反）に該当する。 また、同社は令和４年度の越前町発注工事において、専任の技術者を配置しなければならないところ、建設業法第２６条第３項に違反して、営業所に常勤して専らその職務に従事すべき営業所の専任技術者を主任技術者として配置していたことが判明した。 このことは、建設業法第２８条第１項本文に該当する。
