Designated Investigation Agency | Soil Investigation of Narrow Sites and Operating Buildings | Geotech
Even in narrow sites with existing buildings or operating factories, the buyer's independent investigation using specialized small drilling equipment will identify soil contamination risks in advance.
This is a self-investigation solution designed to accurately assess soil contamination risks while maintaining existing factory buildings or structures on operational sites, or in narrow urban areas where large machinery cannot access. Typically, general environmental surveys assume that the site will be cleared, but decisions regarding land purchases and demolition budgets need to be made before contracts are signed, and waiting for the site to be cleared would not meet business timelines. Our service first identifies the past layout of machinery and the locations of hazardous material handling pits within existing buildings through a "buyer-side historical investigation," accurately narrowing down areas of contamination concern. In the subsequent sampling process, we utilize our own ultra-compact and simple drilling machines that can operate in low-ceilinged interiors and narrow corridors, completing a "voluntary Phase 2 sampling investigation" precisely without disrupting operations. This unique technology allows for a reliable understanding of underground contamination conditions and development risks while leaving the buildings intact before purchase.
basic information
This is a highly mobile and advanced engineering survey specification specialized for confined and low-ceiling sites. In the sampling process, we use a simple mechanical boring machine and a portable soil gas suction device that can be transported with a total width of just a few dozen centimeters, minimizing floor perforation while ensuring reliable soil sampling at depths of several meters. The collected samples are transported to the lab with cross-contamination prevention measures in place, and analyses are conducted based on official methods, issuing measurement certificates with high accuracy equivalent to standard surveys, even in confined spaces.

Applications/Examples of results
It will be introduced in the due diligence of corporate M&A when acquiring real estate through existing factories, buildings, gas stations, printing companies, etc., in urban areas, or while keeping the factory operational. Developers and investors who want to quantify underground environmental liabilities in advance without demolishing the building, as well as managers who want to prevent the expansion of contamination at their operational sites, are using it as an essential practical tool for estimating demolition costs and remediation measures in advance, as well as for making purchasing decisions before the sales contract.
