Designated Investigation Agency | Investigation to Prevent Delays in Condominium Development | Geotech
Prevent delays in large-scale condominium development and construction projects! We provide comprehensive support from usage history investigation to high-precision soil gas analysis and accurate determination of contamination areas.
For developers and general contractors leading urban development and large-scale condominium construction, the unexpected discovery of soil contamination after land acquisition or construction commencement poses a catastrophic business risk, leading to halted excavation work and significant delays with substantial financial losses. This comprehensive survey service is a package designed to preemptively confirm the environmental safety of the land to facilitate the development permit application and consensus-building with neighbors without issues. First, in Phase 1, the utilization history survey meticulously examines the history of the target land using old public documents and aerial photographs to reliably extract often-overlooked risk areas. In the subsequent Phase 2, the on-site survey swiftly conducts high-precision soil gas analysis targeting specific hazardous substances, scientifically identifying contamination conditions alongside surface soil sampling. If any exceedances of standards are recognized, detailed boring will be conducted to determine the extent of contamination, assisting in the optimal grid separation for each condominium construction area and ensuring a reliable off-site disposal plan, thereby achieving budget compliance and schedule adherence for the development project.
basic information
This preliminary comprehensive survey is a specification for designated investigation agencies fully compliant with the Soil Contamination Countermeasures Act, optimized for civil engineering practices in large-scale development and construction excavation. In Phase 1, the historical investigation examines registered land categories, old lot numbers, and closure drawings in metropolitan areas. In Phase 2, the overview survey conducts sampling arrangements tailored to the construction excavation surface and ensures high-precision soil gas analysis for rapid assessment of volatile harmful substances. In Phase 3, the detailed boring survey measures the spread of contaminants in three dimensions and quickly produces and provides accurate three-dimensional CAD drawings of the contamination range and excavation volume calculation data.

Applications/Examples of results
It is utilized for environmental due diligence during land acquisition and for self-confirmation steps before building permit applications in urban redevelopment, condominium development, and commercial building construction projects. By thoroughly covering information from historical land use to determining the extent of contamination before large-scale excavation in each work zone, it significantly accelerates the selection of disposal sites for surplus soil and administrative discussions with local governments regarding compliance with regulations. It plays a crucial role as practical infrastructure to prevent delays in construction and budget overruns due to unexpected soil contamination, ensuring safe and smart removal of surplus soil in compliance with regulations and the timely progress of the project as planned.
