1. The seismic fortification intensity is not specified in the design specification of custom curtain wall, which is one of the important conditions of load combination.
2. The design service life of the structure is not specified in the design specification.
3. In the design specification, only the brand number of the steel is written, not the grade of quality.
4. The welding rod type, weld form and weld quality grade are not specified in the design specification.
5. Steel column feet buried in soil or underground are not indicated or illustrated in the design specification.
6. In the design specification is not written in the hidden frame glass curtain wall, half hidden frame, point support type glass curtain wall must use neutral silicone structural adhesive, and should not use acid silicone structural adhesive, coated glass is more important.
7. It is not stated in the design specification that silicone structural adhesive and weather-resistant sealant must be used within the validity period.
8. The content requirements of compatibility test and reinspection of silicone structural adhesive are not specified in the design specification, and the unqualified shall not be used.
9. It is not stated in the design specification that silicone structural adhesive should not be filled on site except for the all-glass curtain wall.
10. It is not stated in the design specification that the curtain wall glass should use safety glass: which should be laminated? Which ones should be tempered?
11. In the design specification, the important dimension of column and beam section diagram and the minimum wall thickness of important parts are not given.
12. The design specification does not specify the granite plate bending strength; it should be measured by the detection mechanism of its value which should not be less than 8Mpa.
13. It is not stated in the design specification that the same metal curtain wall should adopt the same brand of single and double component silicone structural adhesive, and there is a warranty for the quality of life. The rubber used for stone curtain wall should also have no pollution test report and the supplier to provide test report.
14. In the design specification, the report that the same curtain wall should adopt the same brand silicone sealant and F silicone weather-resistant adhesive compatibility can be used together is not stated.
15. Bolt diameter of curtain wall column, core and connector in the design node diagram is less than M10, some bolts do not wear properly, and some bolts have less than 2, so the bolt strength calculation should be strictly examined.
