This is a strategic soil contamination self-investigation solution developed for real estate investors and M&A practitioners, aimed at fully grasping the sovereignty of land transactions and achieving contract agreements under favorable conditions. In real estate deals, the unseen underground contamination risk is the greatest uncertainty, and if not addressed, the buyer will bear the burden of significant additional costs or development risks due to construction halts after purchase. This service strategically prioritizes "buyer-side historical investigations" during the assessment period before contracts, thoroughly evaluating the likelihood of contamination based on the land's past usage history. Furthermore, if risks are detected, an "independent Phase 2 sampling investigation" is immediately conducted to establish scientific and irrefutable numerical evidence based on official analysis. Armed with this data, buyers can engage in powerful price reduction negotiations with sellers and incorporate strict warranty clauses into contracts, thereby maximizing investment safety and dramatically increasing the overall win rate of the deal.

This is a technology-oriented buyer-side self-investigation solution that thoroughly identifies the residual risks of various specific hazardous substances that were used in the past at sites such as chemical plants and metal processing facilities, and completely clarifies the reality of underground contamination through the highest precision official analysis. Since soil contamination cannot be confirmed visually, the success or failure depends on how deeply the past operational realities can be traced. In this service, the "buyer-side historical investigation" meticulously analyzes the history of raw material usage, manufacturing processes, drainage system diagrams, and Safety Data Sheets (SDS) from the Showa era with professional scrutiny, listing all substances that pose risks without omission. The subsequent field investigation conducts a "voluntary Phase 2 sampling survey" using the most suitable construction method for the target substances, and precise analysis in milligram and microgram units is performed in the lab according to the official methods designated by the Ministry of the Environment. This approach minimizes the development risks of incurring enormous purification costs or project setbacks due to overlooked contamination after purchase, ensuring reliable safety.

In the disposal of excavated soil generated from construction work, preliminary surveys aimed at preventing environmental pollution and avoiding work stoppages are essential. This technology provides the latest analytical methods and survey processes that significantly reduce the analysis costs of construction residual soil while accurately meeting the various regulations and acceptance standards that differ greatly by region and municipality. It covers everything from selecting acceptance sites suited to land and marine reclamation environments to responding to strict volume-based standard values and choosing the optimal construction methods according to the situation. Through Geotech's reliable survey process, it eliminates significant risks such as legal penalties and loss of social credibility associated with improper disposal, thereby fully supporting the smooth progress of projects.

This is an efficient process for soil contamination surveys based on the Soil Contamination Countermeasures Act and the environmental protection ordinances of prefectures. From understanding land use history through Phase I historical investigations to confirming the presence or absence of contamination through Phase II on-site soil and soil gas sampling and chemical analysis, we will respond reliably as a designated investigation agency. We will propose an optimal survey plan that minimizes unnecessary costs.
