Designated Investigation Agency | Historical Site Verification Survey to Mitigate Risks of Rebuilding on Small Lots and During Ongoing Operations
Geographical and historical survey
Break through physical constraints such as factory operating space and indoor floor voids! Completely eliminate the risk of land use change during rebuilding without stopping operations by confirming the land history for the change of use.
When changing the use of part of the site of an operational factory to residential facilities or attached housing and carrying out partial reconstruction, ensuring underground safety without halting operations is an extremely important practical issue for balancing production efficiency and risk management. If construction begins while overlooking the risk of soil contamination lurking beneath the building's floor or in narrow spaces, unexpected environmental liabilities may arise during the construction process, potentially leading to a complete shutdown of both the production line and construction work, resulting in catastrophic losses. This catalog covers advanced approaches to "historical verification of use change" that break through such physical and spatial constraints and proactively address underground risks while operations continue. It explains GeoTech's historical investigation techniques that detail the aging routes of underground piping through the analysis of past operational histories and public notification documents. Additionally, it provides detailed descriptions of special sampling methods, such as simple mechanical boring machines that ensure reliable sample collection even in buildings and narrow spaces, as well as procedures for early acquisition of safety certifications for future residents, making it an essential resource for reconstruction plans during ongoing operations.

basic information
This is a self-investigation service for soil during operations, aimed at sites with physical constraints, provided by Geotech, a designated investigation agency, in full compliance with various guidelines and laws of the Ministry of the Environment. In Phase 1 historical investigations involving changes in use, we conduct detailed tracking of the changes in localized work processes within buildings, in addition to analyzing public notification materials and past drawings, to pinpointedly assess the likelihood of leaks due to the deterioration of impermeable pavements and aging underground piping. Furthermore, in field investigations, we employ specialized sampling techniques such as the SCSC, a simple mechanical boring machine, and self-propelled Dvořák, which can reliably collect deep soil samples even in narrow sites where heavy machinery cannot enter or in low-ceilinged indoor spaces, establishing high-precision component analysis data without halting operations.

Applications/Examples of results
It is utilized for soil risk management during operations when partially changing the use of some buildings and unused land within the premises of a factory that is mainly in active operation, to residential facilities, apartments, or residential areas. The main objectives are to early identify potential contamination in the subfloor of buildings and narrow spaces without stopping the production line, to completely prevent the risk of operational shutdown due to sudden soil contamination discovered during construction, and to quickly establish safety certifications for residents, which are essential for future sales or rental operations. It is optimal for practical work that fully balances the factory's operational profits with effective use of the site, overcoming physical constraints to successfully execute safe redevelopment plans.
