Designated Investigation Agency | Soil Investigation to Prevent Delays in Construction Period During the Demolition and Reconstruction of Cleaning Shops
Soil contamination survey
We will solve the soil contamination risks and leftover soil removal issues associated with the demolition and reconstruction of the cleaning shop, achieving zero construction delays and reducing disposal costs.
This proposal is a comprehensive investigation solution aimed at construction contractors, demolition contractors, and design offices, designed to eliminate the risks of soil contamination and waste disposal associated with the demolition and rebuilding of cleaning stores and factories. In the case of cleaning factory sites, there are concerns about contamination from chlorinated organic solvents such as tetrachloroethylene, herbicides, and metal components from piping that were used in the past, and unexpected contamination discovered during construction can be a major cause of delays and budget overruns. GeoTech Co., Ltd. conducts a seamless investigation as a designated investigation agency, including a historical survey (Phase 1) tailored to the demolition and excavation plans, an overview survey (Phase 2) suitable for narrow sites and existing buildings, and a detailed survey (Phase 3) to determine the extent of contamination. Additionally, we perform rapid soil analysis that complies with local waste regulations and disposal site acceptance standards, thoroughly supporting the separation and proper disposal of contaminated soil. By providing reliable evidence through preliminary investigations, we prevent interruptions in construction, ensuring adherence to timelines and significant cost optimization.

Applications/Examples of results
It is used for early identification of soil contamination risks and for planning safe construction before demolition work or rebuilding of cleaning stores and factories, as well as foundation excavation work. Additionally, it is ideal as evidence for administrative discussions related to building confirmation applications and development permit applications, and for selecting methods for soil purification and containment in underground construction. Furthermore, it can be widely utilized for issuing official analysis result certificates required for procedures that comply with municipal soil regulations regarding construction-generated soil and for pre-transport applications to receiving disposal sites.
