Designated Investigation Agency | Comprehensive Measures to Prevent Delays During Factory Reconstruction | Geotech
Soil contamination investigation
Prevent delays in construction and demolition during factory rebuilding! We provide comprehensive support from usage history investigation to soil gas analysis and accurate determination of contamination areas.
In projects involving the demolition or reconstruction of buildings due to factory shutdowns, halting excavation plans due to soil contamination poses a critical risk that can lead to enormous penalties and delays in construction schedules. This comprehensive investigation package is a technical service designed to perfectly visualize underground contamination conditions before construction begins, ensuring that the building schedule is not affected. First, in Phase 1, a thorough usage history investigation will be conducted to trace past manufacturing line layouts and equipment updates, precisely pinpointing areas of contamination concern. In the subsequent Phase 2 field investigation, high-precision soil gas analysis will be conducted swiftly as a countermeasure against specified hazardous substances, along with surface soil sampling to scientifically identify the contamination status. If contamination is confirmed, detailed drilling in the depth direction will be carried out to accurately determine the extent of the contamination, supporting the development of a reliable and efficient soil removal and purification plan. With trusted evidence as a designated investigation agency, we will safeguard the construction schedule and thoroughly optimize project costs during reconstruction.

basic information
This preliminary comprehensive survey is a technical specification that fully complies with the Soil Contamination Countermeasures Act, seamlessly linked to the demolition and construction processes. In Phase 1, the historical review will thoroughly verify factory operation drawings, specific facility notification documents, and the locations of drainage pits. In Phase 2, the overview survey will utilize portable sampling equipment that can be operated even within active buildings to quickly conduct soil gas analysis for harmful volatile organic compounds. In Phase 3, the detailed boring specifications will involve core sampling to the maximum depth, determining the three-dimensional extent of contamination such as heavy metals, and rapidly delivering detailed three-dimensional contamination maps and cross-sectional data using CAD.

Applications/Examples of results
It will be utilized in the preliminary planning stages for the reconstruction of aging manufacturing plants, the removal of production lines, the demolition of buildings at chemical plants and plating factories, and the construction of new commercial buildings or condominiums on the site. By identifying all environmental risks from historical land use to the determination of contamination areas before the start of architectural design and civil engineering work, it prevents work stoppages due to sudden soil contamination discoveries during construction. This is an essential process to gather objective evidence needed for submitting reports to the relevant authorities, applying for development permits, and providing safe excavation and removal instructions to contractors, ensuring a smooth construction progress without any delays.
