Violation

Machine-translated summary — verify against original

The construction work related to a solar power system contract in Shimonoseki City, Yamaguchi Prefecture, involved land clearing for installing solar panels, including grading based on forest land development permits. Since the work involves clearing forests, the contractor has an obligation to take sufficient measures to prevent sediment disasters. The contractor subcontracted the work to Urban Craft Corporation, which resulted in violations of the conditions of forest land development permit under Article 10-2, Paragraph 4 of the Forest Law, by felling and altering forests outside the project area and within residual forest land. Furthermore, measures such as strengthening temporary disaster prevention facilities and installing sedimentation basins were insufficient. Consequently, in July of Reiwa 6 (2024), heavy rains caused large quantities of sediment to flow outside the project area, damaging nearby rice fields and waterways, and causing harm to the public due to inadequate construction practices.

Other confirmed records for this company

Business Suspension14 Dec 2024
In November 2022, the construction company entered into a contract with a private client in Shimonoseki City, Yamaguchi Prefecture, regarding a solar power generation system. The contract involved the construction company installing the solar power system equipment and selling it to the client, with payment divided into eight installments based on progress. The contract stipulated that if discrepancies were found during inspection after completion, the construction company must perform repairs before handover. Additionally, in December 2022, the construction company transferred the land for the solar project to the client through a land sale contract, and commissioned Urban Craft Corporation to undertake grading and installation work from around December 2022 to November 2023. The contract was a mixed purchase and construction contract, deemed a manufacturing supply contract, and thus considered a construction subcontract under the Building Business Act, making the construction company the direct contractor to the client. The construction company violated the Building Business Act by undertaking construction exceeding the permitted scope without the necessary electrical work permit. In September 2023, the construction company obtained a general construction license for electrical work. However, during the project, it increased subcontracting payments to Urban Craft Corporation without proper permits, violating the Act’s provisions regarding specific construction licenses and exceeding permitted contract amounts. The company also failed to appoint a qualified supervising engineer on-site and did not prepare required construction management documents. Furthermore, the company did not assign qualified engineers or prepare necessary construction management documents, violating the Building Business Act. Initially, the company only subcontracted land grading to Urban Craft Corporation, but from November 2023, after obtaining an electrical work permit, it subcontracted electrical installation work, including solar equipment installation, to the same company, and paid 50 million yen, violating the Act by engaging in electrical construction without the proper permit.
