It depends on the specific content and evaluation results of the occupational disease hazard pre-evaluation report.

The review opinions of the construction unit generally focus on: Whether the types of occupational disease hazards and the severity of the hazard consequences were taken into account during the project design, whether there are corresponding measures to avoid or reduce the hazards, and whether the degree of hazards after taking measures is within the acceptable range. Within the acceptable range.

If the hazard is small and acceptable, then the design is feasible. If this is not acceptable then the design should be changed and the investment in protection involved may be increased. If investment increases a lot, perhaps the construction unit should consider whether to proceed with construction? Or change the construction plan, etc.
