Soil contamination risk assessment and measures before dismantling

In the demolition industry, it is important to confirm the presence or absence of soil contamination associated with building demolition work. Particularly, depending on the historical land use, there may be unintentional soil contamination, and it is necessary to understand this risk in advance and respond appropriately. If soil contamination is identified, there is also a risk of delays in demolition work and additional costs.
