There are various important points specified in the Ministerial Regulation as follows:
- Revising and adding the definitions of areas where those can be affected by the earthquake vibration dividing into 3 levels (i.e., area 1: ordinary level of earthquake vibration, area 2: mid-level of earthquake vibration and area 3: high-level of earthquake vibration)
- Adding the definitions of planner and plan calculator.
- Amending the building-planning processes that the planner shall consider for the building’s plan based on each area according to item a. For example, the planner of the building located at area 3 shall consider architectural components consisting of stability and indestructibility.
- Amending the building-planning process and building-construction calculation in that the planner and plan calculator of the building located at area 2 or 3 have to arrange for the whole structure, its details and joining parts according to the ministerial regulation and rules and regulations prescribed by the relevant authorities.
