Designated Investigation Agency for Real Estate Development | Phase 1 Historical Land Investigation at the Time of Land Sale
Eliminating transaction risks through due diligence investigations.
In the real estate development industry, assessing the risk of soil contamination in land transactions is essential for the smooth progress of projects and the maintenance of asset value. Particularly when the development area exceeds 3,000 m², there is an obligation to conduct investigations based on the Soil Contamination Countermeasures Act, requiring appropriate responses. If unexpected soil contamination is discovered, additional remediation costs and delays in construction schedules may arise, significantly impacting business plans. Our historical investigation (Phase 1), as a designated investigation agency by the Ministry of the Environment, provides investigations based on reliable technical specifications to identify and eliminate these risks in advance. 【Usage Scenarios】 - Risk assessment before land purchase and handover - Compliance with legal investigation obligations for areas exceeding 3,000 m² - Prevention of transaction disputes 【Benefits of Implementation】 - Reduction of asset value decline risk - Prevention of transaction disputes - Assurance of legal compliance - Understanding the impact on objective price formation
