We will assess the soil contamination risk before land clearance and support smooth demolition work.

As demolition professionals proceed with land clearing, particularly on former automobile maintenance factory sites, there may be a latent risk of soil contamination due to past usage. There is a possibility that organic solvents used for cleaning and degreasing, or lead and hexavalent chromium from putty polishing and anti-corrosion plating, have leaked into the ground. If such contamination is discovered during the demolition work, additional investigations and remedial measures may be required, leading to the risk of delays and unexpected costs. Therefore, it is crucial to objectively ascertain the presence of soil contamination before commencing demolition work to ensure safe and timely land clearing. Our soil contamination surveys, as a designated investigation agency, provide consistent support from historical investigations to detailed surveys, offering reliable evidence to facilitate smooth demolition work. 【Usage Scenarios】 - Before demolition work on former automobile maintenance factory sites - When considering land sale or redevelopment after land clearing - When wanting to understand potential environmental liability risks in advance 【Benefits of Implementation】 - Reduction of the risk of unexpected contamination discovery during demolition work - Control of delays and additional costs - Achievement of safe and planned land clearing - Prevention of troubles in land transactions

Applications/Examples of results

The main purpose is to conduct environmental due diligence (environmental DD) prior to real estate sales contracts associated with the redevelopment of sites such as automobile maintenance and body painting factories, as well as in corporate M&A transactions. It is utilized to allow the buyer side of the land to take the lead in quantifying and evaluating hidden defect risks and future asset retirement obligations in advance. Additionally, it can be widely applied in practical administrative consultations and contract risk management during large-scale land redevelopment exceeding 3,000 square meters, the fulfillment of obligations under Articles 3 and 4 of the law associated with the submission of notifications for the abolition of specific facilities using designated harmful substances, and the implementation of pre-inspections for off-site transportation of construction-generated soil based on various ordinances (28-item leaching and content tests).
