Violation

On January 31, 2022, Yamaguchi Prefecture revoked the general construction business permit for Ikawa-gumi Ltd. (corporate number 9250002008074), located at 2-9-7 Kanda-cho, Shimonoseki City, Yamaguchi Prefecture. The revocation was based on the company's failure to meet the placement standards for a dedicated technical expert in the demolition construction sector, after the transitional measure that permitted companies meeting the 'scaffolding and earthwork' sector standards at the time of the enforcement of the amended Construction Business Act (Law No. 100 of 1949) on June 1, 2016, to continue doing so until June 30, 2021, ended. The amendment introduced the 'demolition construction' sector as a new category eligible for construction permits, and the transitional measure allowed certain companies to meet the new sector's standards by satisfying the standards of the 'scaffolding and earthwork' sector until June 30, 2021. After this period, Ikawa-gumi Ltd. no longer met the requirement for a dedicated technical expert in the demolition sector, leading to the license cancellation.

Cause of action

平成２８年６月１日施行の建設業法（昭和２４年法律１００号）の改正により、建設業許可の対象に「解体工事業」が新設された。 これに伴い、当該施行日時点で「とび・土工工事業」の専任技術者の配置基準を満たしている者は、令和３年６月３０日までの間に限り、「解体工事業」の専任技術者の配置基準を満たす取扱いとする経過措置が講じられた。 この経過措置が終了したことにより、有限会社井川組は解体工事業の建設業許可において、建設業法第７条第２号に掲げる専任技術者の配置基準を満たさなくなった。
