1.0.1 This code is formulated with a view to strengthening the quality control of building works, and unifying the acceptance of constructional quality of concrete structures.

1.0.2 The code is applicable for the acceptance of constructional quality of concrete structures of building engineering, not applicable for the acceptance of constructional quality of special concrete structures.

1.0.3 Requirements for acceptance of constructional quality specified in the technical documents and contract documents of concrete structures shall not be lower than the regulations of this code.

1.0.4 The code shall be used together with national standard “Unified standard for acceptance of constructional quality of building engineering” GB 50300-2001.

1.0.5 Besides following this code, the acceptance of constructional quality of concrete structures shall also comply with the regulations of relevant current national standards.
