Q3-1 What pre-survey is required when applying for permission?

Ground survey is the basis of the development plan, so please carry out it appropriately according to the contents of the plan. In particular, when designing the retaining wall that always receives soil pressure, obtain detailed ground data, such as various soil constants.
In addition, please conduct a survey on the surrounding land and houses in advance, and set up the application area and plan a development plan, taking into account the impact of the construction.
