Designated investigation agency | Managing potential soil contamination risks before large-scale development to prevent delays.
Soil contamination investigation
Before the commencement of urban development and construction projects, the potential contamination risks of the ground are visualized through voluntary historical surveys and precise sampling conducted by designated investigation agencies.
In projects involving construction, civil engineering, or large-scale land modifications, the discovery of unexpected soil contamination after excavation begins can lead to temporary work stoppages and delays in the removal of excess soil, directly resulting in serious project delays and budget overruns. This service is a voluntary investigation solution designed to avoid such sudden risks at construction sites and support the reliable progress of projects. Utilizing the expertise of a designated investigation agency, we quickly conduct a comprehensive desk-based evaluation of the land's historical background through voluntary historical investigations, as well as precise depth-specific sampling analyses tailored to foundation piles and excavation plans before construction begins. By visualizing the safety of the ground with reliable evidence beyond the legal investigation obligations, we enable the optimization of construction plans and the proper design of contaminated soil treatment. This robustly supports the elimination of unforeseen troubles and additional costs, ensures accountability to clients, facilitates smooth risk management between clients and general contractors, and preserves the asset value of the construction projects.

basic information
This is a self-investigation specification that meets the standards of designated investigation agencies and can be introduced during the design phase before construction work. In the historical investigation, the registry transcripts, old maps, aerial photographs, geological maps, and environmental-related materials from the administration of the target area are comprehensively examined to evaluate and map the potential contamination risks within the excavation planning area. In the sampling investigation, appropriate sampling of surface soil and soil gas covering Type 1 to Type 2 specific hazardous substances is conducted according to the layout of the work area and the planned excavation depth (from surface to deep layers). The report includes precise analysis data from a measurement certification business that fully complies with the official methods announced by the Ministry of the Environment, and a self-initiated soil contamination investigation report suitable for practical use is issued in a short period for confirmation applications of construction plans and submissions by the client.

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 by operators to independently confirm the safety of underground areas, with the aim of preventing 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, ensuring appropriate risk disclosure to general contractors, explaining environmental measures to surrounding residents, and facilitating overall budget management of the project.
