Applications/Examples of results

It is utilized for pre-disposal inspections and compliance certification of construction-generated soil and surplus soil arising from excavation in building and civil engineering works, as well as underground development. It is particularly suitable for situations requiring official evidence to obtain approval for transporting soil to disposal sites such as unique surplus soil regulations in Chiba Prefecture and the Tokyo Port terminal. Additionally, it is implemented in various construction and real estate development scenarios, including soil contamination risk assessment in land transactions and asset evaluations, preventive maintenance during factory reconstruction and operations, and mandatory investigations based on laws related to the closure of specific facilities. This system is essential for eliminating barriers to construction progress in advance and achieving a high level of cost reduction while ensuring complete compliance.
