We will achieve the acceleration of soil acceptance judgment and the optimization of analysis costs through a survey design that complies with municipal regulations.

In civil engineering sites, accurately meeting the regulations and acceptance criteria set by each municipality for the disposal of excavated soil is essential for the smooth progress of construction. Delays in confirming compliance with these standards can lead to project stagnation, while improper handling directly results in legal risks and a decline in social credibility. This service encompasses the complex acceptance criteria that vary by region and designs an optimal investigation process, thereby achieving both the acceleration of acceptance judgments and the optimization of analysis costs, supporting the stable advancement of projects. 【Usage Scenarios】 - Confirmation of compliance with soil acceptance criteria based on municipal regulations - Soil analysis associated with transportation to land and marine reclamation sites - Rapid sampling and analysis in line with construction schedules 【Benefits of Implementation】 - Accelerated acceptance judgments through investigation designs compliant with regulations - Optimization of analysis costs by selecting sampling methods according to conditions - Reduction of improper handling risks and smooth progress of construction

Applications/Examples of results

Development of disposal plans for excavated soil before the start of construction and civil engineering works, pre-compliance analysis based on regulations from various municipalities (Chiba, Tokyo, Saitama, etc.), approval procedures for transporting to disposal sites, and voluntary residual soil risk management associated with land sales and construction. It is utilized for pinpoint soil sampling and screening surveys at sites where large machinery cannot easily access, such as narrow plots, operating factories, and directly beneath underground pits.
