The pre-evaluation is required at the feasibility stage. So it is done first. Pre-assessment done, and then do the design chapter, the design chapter is the pre-assessment of occupational hazards involved in the post protection design. (This is really the design institute to do).
This is a reference to the Safety Supervision Bureau Order No. 51 in the express provisions of the first pre-assessment, and then the design of the special part of the final control assessment. The first is the design of the design, then the design of the special section, and finally the control of the assessment. The current review process of the Safety Supervision Bureau is still so. The control of the evaluation of the material sent for review when you need to give the safety supervision bureau to provide the design of the special part of the information.
