This can be used as a guideline for smartly explaining the ground risk and the rationale behind the foundation specifications to clients during the sales scene of custom-built homes and initial design meetings. It is particularly effective for follow-up discussions and dispelling distrust when reinforcement work is required in soft ground areas such as former rice fields or low-lying lands, leading to an increase in estimated costs. Additionally, it is ideal as an educational text for sales representatives and young designers within the company, standardizing the skills for accurate interpretation of ground assessment reports and the ability to explain to clients, thus contributing to improved customer satisfaction and expedited contract processes.
