Blocking environmental liability risks in corporate M&A and asset securitization! Comprehensive support from usage history investigation to soil gas analysis and precise contamination range determination.

In the practical work of corporate organizational restructuring, M&A, or the securitization and sale of idle assets and factory sites, latent soil contamination underground is the biggest bottleneck that can lead to massive compensation claims in later stages. This comprehensive investigation service is a seamless environmental solution designed to completely eliminate uncertainties in investment decisions and due diligence, and to determine the appropriate corporate and land value. First, in Phase 1, the usage history investigation analyzes public documents, old maps, and administrative materials from multiple angles to thoroughly identify the historical risks of the target land. Next, for the risk zones of specific hazardous substances, Phase 2 involves a rapid on-site survey with soil gas analysis and surface sampling to scientifically quantify the presence of contamination. If contamination is confirmed, we immediately transition to a detailed investigation to accurately determine the extent of the contamination and logically estimate the costs necessary for remediation. The rigorous techniques and evidence as a designated investigation agency strongly support your company's safe asset liquidation and the success of strategic M&A.

basic information

This comprehensive survey complies with the environmental due diligence standards for M&A and real estate securitization, and is a specification that fully incorporates the measurement methods of the Soil Contamination Countermeasures Act. In Phase 1, a historical investigation will track the changes in the registered land use of the target site, interpret aerial photographs, and verify hazardous substance handling notifications. In Phase 2, a general survey will conduct sampling based on official standards such as a 10-meter mesh, and perform high-precision soil gas analysis (quantitative analysis using GC-MS, etc.) for first-class hazardous substances, as well as surface soil sampling and measurement. Furthermore, in the detailed investigation, depth-specific sampling of oil and heavy metals will be conducted to accurately determine the extent of contamination and prepare a report on the estimated costs for countermeasures.

Applications/Examples of results

It is utilized as an essential step in environmental risk due diligence during corporate mergers and acquisitions, asset valuation during group reorganizations, trust beneficiary rights conversion, land securitization, and external sales of factory sites. By fully packaging the process from historical research to determining the extent of contamination before contract agreements, it completely visualizes off-balance-sheet environmental liability risks. For the seller, it serves as proof of integrity to prevent post-transaction damages, while for the buyer, it plays an extremely important role as investment defense data for proper price negotiations and to mitigate unforeseen losses.
