Designated Investigation Agency | Soil Comprehensive Survey Procedure to Accelerate Compliance with Regulations
Soil cost optimization survey that clears the standards of municipal ordinances and laws, supporting rapid development permits through phased sampling in phases 1 to 3.
This document is a practical manual for general contractors, developers, and site management officials of factories, created to fully comply with the soil contamination countermeasure ordinances and construction-generated soil (excavated soil) related ordinances established by prefectures and municipalities. It aims to dramatically expedite the commencement of projects through a phased comprehensive soil investigation. When changing the characteristics of land over a certain area or discontinuing specific facilities, there is an obligation to notify the authorities in advance and conduct investigations based on the ordinances. However, procedural deficiencies and unexpected contamination discoveries can lead to significant delays in the development schedule. This manual provides a step-by-step explanation of the process from phase 1, which involves a thorough historical examination of the site in full compliance with municipal requirements, to the efficient transition to phases 2 and 3. By introducing "incremental sampling," which eliminates excessive on-site work and unnecessary analysis items, it clearly outlines an approach to minimize the total costs of official analysis and achieve reliable optimization of investigation costs. The extensive practical know-how possessed by the designated investigation agency, Geotech, strongly supports smooth administrative consultations and the swift acquisition of development permits.
basic information
As the technical specifications for comprehensive soil surveys suitable for municipal regulations, we will conduct a design that strictly meets the investigation requirements set forth by the Soil Contamination Countermeasures Act and the environmental conservation ordinances of each local government (such as metropolitan areas and large urban areas). In Phase 1, we will conduct preliminary checks at municipal offices, thoroughly examining land alteration histories and chemical substance handling notification documents. In Phases 2 and 3, sampling will be promoted based on the designated grid layout specified in the ordinances, implementing a phased sampling approach. The collected samples will be measured using public analytical methods based on measurement certification business registration and delivered as compliance certification reports that can be submitted directly to the authorities.

Applications/Examples of results
This survey method is utilized for prior notification during changes in land characteristics for areas exceeding 3,000 square meters, large-scale residential land development on former factory sites, and mandatory investigations related to the dismantling and renovation of facilities handling specific hazardous substances as defined by municipal soil regulations. It provides objective safety verification in the preparation of application documents for administrative agencies, significantly speeding up the review and prior consultation processes. By accurately obtaining phased data in advance, it allows for the early identification and elimination of non-compliant areas, helping to avoid construction delays and facilitating the swift acquisition of development permits as public evidence.
