Optimized soil survey manual! Covers keywords searched by purchasing agents and eliminates procedure rejections.

We provide high-precision public analysis solutions to completely eliminate the risk of construction interruptions in response to the stricter soil disposal regulations and acceptance standards at construction sites across the country, starting with the metropolitan area. In the practical handling of soil removal, a mistake in the preliminary specification confirmation process can lead to immediate rejection of acceptance, resulting in a significant increase in total costs on site. Our company reliably implements "full-layer sampling according to excavation depth," as stipulated in regulations such as those in Chiba Prefecture, using advanced boring techniques like dry excavation, and perfectly meets the additional analysis requirements for oil content and dioxins that vary by disposal site. Furthermore, based on the principle of "no reuse of existing data" encountered in public works registration practices, we quickly establish solid evidence unique to the specific site and lot. Even in urgent situations, we streamline the entire process from sampling to analysis, issuance of measurement certificates, and support for administrative procedures in a one-stop manner, ensuring a reliable removal system that does not halt construction. Please feel free to consult with us first.

Inquire About This Product

basic information

This is an environmental analysis specification compliant with regulations, designed to smoothly obtain acceptance approval for excavated soil and construction-generated soil arising from construction work. Sampling adopts a full-layer, uniform sampling specification corresponding to the maximum design depth of soil alteration (using impact penetration and rotary dry excavation methods), completely shutting out secondary contamination between samples. Analytical measurements comply with official methods and cover not only specific hazardous substances but also additional analysis items such as oil concentration and dioxins, which may be uniquely required by disposal sites. It supports the rapid issuance of a complete set of measurement certificates and documents linked to the construction plan, which can be directly used in public works and registered practices at construction sites within the city, where the reuse of data from other sites is prohibited.

Applications/Examples of results

It is used to obtain smooth transportation approval for construction-generated soil from large-scale civil engineering and building foundation works to private disposal sites and municipal designated acceptance areas. Thorough pre-specification checks are conducted based on the standards and regulations of the disposal sites to eliminate the risk of work interruptions. This includes full-layer sampling to the maximum excavation depth using methods such as dry excavation, detection of additional analysis items unique to the disposal site, such as oil content and dioxins, and individual registration procedures for each lot in accordance with the principle of "no reuse of existing data" imposed on public works in the city. This application streamlines complex environmental risk management and administrative application procedures, ensuring compliance with construction schedules and significantly reducing soil disposal costs.
