Our service conducts a "buyer-side historical investigation" during the due diligence period before contract signing to objectively verify the authenticity of the seller's information disclosure. Furthermore, if there are suspicions of contamination, we proceed to a "voluntary Phase 2 sampling investigation" that has legal evidentiary value, establishing solid numerical evidence based on official analysis. Based on this scientific data, we clearly define the burden-sharing of remediation costs and special clauses regarding defect liability within the sales contract, completely eliminating the development risk of the buyer incurring unexpected cleanup costs. This is a strategic solution to maximize the safety of land transactions from a legal and contractual perspective.

This is a soil contamination self-investigation solution specialized for developers and construction companies planning the construction of logistics warehouses, distribution centers, and large commercial facilities before land acquisition. In the development of vast land, the past usage patterns are often diverse, and overlooking partial contamination risks can be fatal. This service aims to fully protect the interests of the buyer by first thoroughly examining the historical usage of the entire site through a "buyer-side historical investigation." In areas where the possibility of contamination cannot be completely ruled out, a "voluntary Phase 2 sampling investigation" is quickly deployed to directly detect and evaluate soil gas and harmful substances underground through official analysis. This prevents the greatest development risk of exposing contaminated soil after construction begins, which could lead to long-term halts in construction work and the collapse of business plans and tenant attraction. By obtaining accurate risk information in advance, it enables proper management of the project budget and negotiations for land price reductions, guiding the project to success on schedule.

This is a self-investigation solution aimed at preemptively blocking the greatest management risk of "soil contamination" in corporate M&A and real estate transactions involving former factory sites, thereby avoiding corporate environmental liabilities. Instead of relying solely on self-reports from the seller, it thoroughly clarifies the past operational history and handling of hazardous substances through a "buyer-led historical investigation." Furthermore, for areas where risks are confirmed, a "voluntary Phase 2 sampling survey" is swiftly conducted on-site, quantifying the contamination levels of soil and groundwater as scientific analytical data. This allows for the complete prevention of the risk of incurring enormous remediation costs and the collapse of business plans after purchase, all before the contract is signed. Utilizing extensive experience and expertise as a designated investigation agency, we provide comprehensive support from optimal risk assessment to early cost estimation of countermeasures to prevent future asset value decline. This is an essential environmental due diligence to fulfill accountability to stakeholders and establish safe and transparent business deals.

This is a solution that explains the comprehensive voluntary soil contamination investigation conducted by the buyer to prevent business setbacks caused by "soil contamination," which is the greatest potential risk in land transactions and real estate development. Rather than relying solely on information disclosure from the seller, the investigation aims to ensure safety before land purchase, starting with Phase 1, the "Buyer-side Historical Investigation," which thoroughly uncovers the history of past use of specific hazardous substances and the potential for underground infiltration. If further risks are a concern, a "Voluntary Phase 2 Investigation" will be conducted on-site, where soil gas and sample sampling, along with official analysis, will quantify the presence and concentration of contamination as scientific evidence. This approach effectively avoids critical development risks such as unexpected contamination discoveries leading to delays in construction schedules or business setbacks after the commencement of construction work. In the event of contamination being discovered, it is also possible to calculate countermeasure methods and purification costs in advance, allowing for advantageous negotiations regarding warranty clauses and price adjustments in the sales contract. We provide high-precision investigation services unique to designated investigation agencies that support asset value preservation and safe real estate investment.

We fundamentally solve the significant risks faced by purchasing managers and site managers in construction and civil engineering, such as "unable to find a disposal site for surplus soil" and "refusal of acceptance after commencement," through high-precision public analysis technology conducted in advance. To meet the different surplus soil regulations set by each municipality and the strict acceptance criteria established by private disposal sites, we have streamlined a reliable specification confirmation procedure into a workflow. From conducting comprehensive sampling of all layers at the excavation depth required by regulations such as those in Chiba Prefecture, to covering unique additional analyses for disposal sites, including oil content and dioxins, and even to the new registration procedures for site-specific materials deemed non-reusable, we back up all processes in a one-stop manner. We issue robust evidence with measurement certificates in the shortest possible time, completely eliminating vehicle waiting losses and construction delay risks, and support the development of the cleanest and most cost-effective disposal plans. Please feel free to consult with us.

Proper disposal of construction-generated soil arising from the excavation process is a critical issue directly linked to the project's profit margins and adherence to deadlines. Our company provides high-precision official analysis and sampling services as a designated investigation agency under the Soil Contamination Countermeasures Act, ensuring full compliance with strict residual soil regulations and individual acceptance criteria at disposal sites nationwide. Even within tight schedules before construction begins, we clarify the procedures for pre-specification confirmation that clients and construction managers need to know, and we ensure comprehensive layer sampling according to excavation depth. We cover not only standard hazardous substances but also additional analysis items unique to disposal sites, such as oil content and dioxins, completely eliminating issues of acceptance refusal due to lack of evidence. Furthermore, we respond to the increasingly strict principle of "no reuse of existing data" in public works projects in the city, rapidly creating and supporting the latest registration documentation tailored to the specific lot of the relevant site. We deliver optimal residual soil disposal solutions that ensure construction never stops.
