[Excavated Soil Survey] Procedures for Confirming Excavated Soil for Clients to Eliminate the Risk of Construction Delays
Soil survey
Thoroughly eliminate the risk of temporary work interruptions! We provide one-stop support from the procedures for pre-specification checks that clients should know to high-precision official analysis.
In recent years, in land transactions and construction projects, early soil contamination measures during operations and the establishment of reliable evidence for construction-generated soil have become essential to avoid asset value decline due to soil contamination and troubles related to the rejection of surplus soil. As a designated investigation agency under the Soil Contamination Countermeasures Act, our company provides investigation techniques that meet all site needs, from boring in narrow sites to official analysis of large-scale surplus soil. Particularly in surplus soil disposal, we standardize procedures for pre-specification confirmation to eliminate the risk of construction delays and ensure the implementation of "full-layer sampling according to excavation depth" that complies with regulations such as the Chiba Prefecture surplus soil ordinance. We can quickly respond to the unique practical bias of public works that prohibits the reuse of existing data by disposal site, with a sampling plan directly linked to the site. We also identify additional analysis items unique to disposal sites, such as oil content, dioxins, and heavy metals, and issue measurement certificates. From the registration practices for public works in the city to clearing various surplus soil ordinances, we strongly support the procedural tasks of purchasing personnel and technical managers, ensuring efficient soil and surplus soil management that does not halt construction.
Inquire About This Product
basic information
This is a residual soil specification compliance inspection system conducted by a designated investigation agency, in accordance with the Soil Contamination Countermeasures Act and national construction-generated soil management standards. It utilizes a crawler-mounted hydraulic hammer drilling machine capable of dry excavation and a dual-tube sampler with a rotary sleeve, allowing for precise full-layer sampling tailored to the maximum depth of root excavation. Analytical measurements are conducted using official methods compliant with the Ministry of the Environment's notifications (leaching tests and content tests), and it also accommodates additional measurements for items such as oil content, dioxins, heavy metals, and pH. The issued measurement certificates can be directly used for registration with local governments and disposal sites, enabling the fastest possible acceptance approval and transportation permit acquisition under non-transferable rules.

Applications/Examples of results
Urban redevelopment, the utilization of former factory sites, and infrastructure civil engineering works such as roads and railways utilize suitability certification to properly transport and accept excavated soil (excess soil) to disposal sites and recycling plants. It not only clears regulatory requirements but also ensures zero risk of work interruption on-site through pre-specification checks, vertical all-layer sampling according to excavation depth, and simultaneous execution of additional measures for specific items such as oil content and dioxins unique to disposal sites. In the registration practices of public works in the city where the reuse of existing data is not permitted, it provides solid official analytical data specific to the site quickly, supporting a dump truck operation plan without delays.
