Narrowing down soil contamination risks through a phased approach and optimizing investigation costs.

In the construction industry, it is essential to accurately assess the presence of soil contamination to ensure land safety and avoid future risks. Particularly in new construction and large-scale renovations, hidden environmental risks can lead to project delays and additional costs. Excessive investigations in the early stages can increase cost burdens, so an efficient and reliable approach is crucial. Geotech's comprehensive soil investigation optimizes investigation costs while narrowing down the potential for contamination through phased investigations from Phase 1 to Phase 3, ensuring reliable evidence. 【Usage Scenarios】 - Before purchasing land for new construction - Before rebuilding or renovating factories and facilities - Evaluating environmental risks in land transactions - Environmental surveys around existing facilities 【Benefits of Implementation】 - Reduction of unnecessary analysis points and labor costs - Acquisition of reliable legal evidence - Reduction of hidden defect risks after handover - Maintenance of corporate social credibility and asset value

Applications/Examples of results

This survey method is utilized for voluntary investigations aimed at understanding legal obligations during the sale and purchase of land by companies, the rebuilding of factories and business sites, and the closure of specific facilities. It is also applicable for pre-assessing environmental liabilities during M&A or organizational restructuring. Additionally, it serves as optimal supporting documentation for compliance with off-site transportation standards for excavated soil and surplus soil during condominium development and land acquisition by developers, as well as for mitigating legal risks in important matter explanations. In practical situations where reliable soil sampling is required in restricted spaces where large machinery cannot enter, such as small plots of land, operational factory sites, and indoor parking lots, it supports cost reduction through phased narrowing and facilitates rapid administrative consultations and the acquisition of development permits.
