Soil investigation: Compliance investigation of soil removal standards to prevent construction interruption through prior specification confirmation.
Soil survey
Completely meets the Soil Contamination Countermeasures Act and local government soil disposal regulations! Provides reliable analytical surveys that perfectly fit the strict acceptance standards of each disposal site.
The disposal of construction-generated soil (such as leftover soil from root excavation) that arises from construction work and development activities has become a very complex process due to increasingly stringent soil contamination measures, local government soil disposal regulations, and private standards set by disposal sites. If the procedure for confirming specifications in advance is incorrect, it may result in non-compliance after construction begins, leading to temporary site interruptions and significant risks of delays. This technical proposal thoroughly covers "full-layer sampling according to excavation depth" to fully comply with the regulations of major municipalities, including the Chiba Prefecture soil disposal ordinance, as well as additional analysis measures for different disposal sites, such as oil content and dioxins. We provide the latest official analysis and application support services in a one-stop manner, based on strict constraints such as the inability to reuse existing data for registered practices in public works in Tokyo. This optimal soil analysis solution balances cost reduction and the establishment of high-precision evidence, eliminating the need for rework in construction.

Applications/Examples of results
Construction-generated soil (construction residual soil) that arises from various building and civil engineering works, such as root excavation and foundation digging, is utilized in situations where it is safely transported and disposed of in compliance with local government residual soil regulations (such as Chiba Prefecture's residual soil regulations) and the acceptance standards of private disposal sites. Additionally, it serves as essential official evidence during the preparation of construction plans for public works in the city, the practicalities of new registrations for designated disposal sites, and the procedures for prior notifications and approvals to the authorities. It directly contributes to optimizing on-site construction management and cost reduction by preventing work interruptions through pre-construction specification confirmations, comprehensively covering additional analyses for oil content and dioxins as specified by disposal sites, and responding swiftly to rules prohibiting the reuse of data from other sites.
