Soil contamination investigation

last updated：Sep 07, 2026

ジオテック

Before the start of residential development, a designated investigation agency visualizes the potential contamination risks of the ground.

For house builders, the integrity of the ground is crucial for safe construction and smooth progress of the construction schedule. In particular, if unexpected soil contamination is discovered after excavation begins, it can lead to temporary work stoppages and delays in soil disposal, directly resulting in project delays and budget overruns. This service is a self-investigation solution designed to avoid such risks and support the reliable progress of projects. Utilizing our expertise as a designated investigation agency, we conduct voluntary historical land surveys to assess the past history of the land, as well as precise sampling analyses tailored to foundation plans, all before construction begins. By visualizing the safety of the ground as evidence in advance, we can optimize construction plans and design appropriate treatment for contaminated soil, thereby preventing unforeseen troubles and additional costs from arising. 【Usage Scenarios】 - Before purchasing or developing residential land - During the design phase before building confirmation application - Accountability to clients 【Benefits of Implementation】 - Reduced risk of construction delays - Control of additional costs - Smooth progress of projects - Preservation of asset value

Applications/Examples of results

It is utilized for pre-risk management of large-scale civil engineering projects that require private-sector-led development activities, rebuilding of buildings and factories, or notifications for changes in land characteristics. Before the start of construction or during the excavation design phase, it is used for operators to voluntarily confirm underground safety and to prevent secondary damage from the spread of contaminated soil and delays in the disposal of surplus soil. By securing objective voluntary historical investigation reports and depth-specific sampling analysis results in advance, it functions as an essential practical tool for improving the accuracy of construction estimates, appropriate risk disclosure to general contractors, explaining environmental measures to surrounding residents, and smoothly managing the overall project budget.
