V. Review and Approval of Drawings:
1. To ensure the standardization of drawings and reduce errors, construction drawings must be reviewed by senior designers (including senior level) according to the "Drawing Standards Inspection Form," approved by the department manager (supervisor), and the department manager (supervisor) inspects the prefabricated home product image files.
2. If drawings are penalized during random checks: In the case of "Wan Jia Deng Huo," the drawing designer is penalized 50%, the scheme designer 20%, the team leader 15% (if no team leader, then the scheme designer bears this responsibility), and the reviewer 15%. In the case of "Yang Chun Bai Xue," the drawing designer is penalized 50%, the scheme designer 35%, and the reviewer 15%.
3. Drawing reviews should be completed before the owner signs off, or if special reasons arise, before submission to the budget department.
4. Review content: Whether it conforms to the drawing standards; whether there are omissions or defective annotations and textual explanations; whether there are obvious drawing errors.
5. Drawing approval should be completed before submission to the budget department.
6. Re-review and recheck contents: feasibility of design results and construction techniques.
