Assessment and management of soil contamination risks in the change of use of former factory sites.

When selling and redeveloping former chemical industry factory sites for residential use, the opaque costs associated with underground soil contamination measures pose a significant risk in the business plan. If a severe contamination is discovered after the land sale without prior historical investigations, high remediation costs may arise, leading to project setbacks. This service provides "historical verification for land use change" to control such uncertain risks and visualize and budget the full scope of remediation costs in advance. It covers everything from the scrutiny of public notification documents to preventive management to prevent contamination spread, and sampling investigations for selecting optimal construction methods, thereby managing budget risks and achieving cost reductions. 【Usage Scenarios】 - Conversion of factory sites to residential land - Understanding the presence and extent of soil contamination - Preliminary estimation of remediation costs - Ensuring transaction safety 【Benefits of Implementation】 - Mitigation of unexpected remediation costs - Reduction of transaction cancellation risks - Support for budgeting in business plans - Selection of optimal cost-reduction methods

Applications/Examples of results

It is mainly used for budget management and cost optimization before contracts when changing the use of factory sites or commercial land to residential areas or condominiums for sale or redevelopment. The primary objectives are to visualize unexpected countermeasure costs through detailed historical investigations, to negotiate favorable specific defect liability clauses to be included in the sales contract, and to build evidence for selecting cost-effective countermeasure methods while avoiding expensive soil replacement methods. It is ideal for practical work that completely controls the opaque risks of land conversion, fully avoids unexpected financial burdens and transaction cancellations, and achieves healthy disposal while maximizing the long-term asset value of the land.
