Speed diagnosis to keep the project on track! Optimize Phase 1 investigations and efficiently screen documents to eliminate hidden defect risks before the contract.

In real estate development and construction/demolition sites, the discovery of hidden defects related to soil contamination after contract signing or just before construction begins poses a serious management risk, potentially leading to long project delays and enormous compensation claims. Especially in land transactions where speed is essential, traditional time-consuming investigation methods can become a significant disadvantage. This explanatory document provides detailed practical know-how on "optimizing Phase 1 investigations" to extract underground risks in a short period without delaying the development schedule. Geotech, a designated investigation agency under the Soil Contamination Countermeasures Act, has established efficient document screening to quickly scrutinize past public notification materials and detailed land histories. By implementing this optimization of document investigation, excessive on-site verifications are thoroughly eliminated, achieving low-cost and high-speed environmental diagnostics that do not impact construction timelines. It prepares legal evidence to strongly supplement important explanations in advance and covers how to incorporate special provisions into the sales contract. This book aims to accelerate reliable real estate transactions while maintaining social credibility.

Applications/Examples of results

In the land acquisition and sales brokerage practices undertaken by demolition contractors, construction companies, and real estate developers, where speed and shortened construction periods are required, this will be utilized as supplementary materials for risk management and important matter explanations prior to contracts. We propose its introduction as a low-cost environmental diagnosis that quickly extracts hidden defect risks before project commencement. By completely eliminating unnecessary sampling through document screening, it rapidly builds neutral evidence for the formulation of defect liability clauses in contracts and for reduction negotiations, and is widely used to promote smooth and safe real estate transactions.
