GB 50206-2012 in English

1.0.1 This code is formulated with a view to strengthening the quality management of construction work, unifying the construction quality acceptance of timber work and guaranteeing the project quality.
1.0.2 This code is applicable to the construction quality acceptance for timber structure works like rough sawn and round timber structure, glued-laminated timber structure and light wood frame construction.
1.0.3 The construction quality acceptance of timber structure work shall be based on engineering design document. The requirements of construction quality acceptance in design document and engineering contracting contract shall not be lower than those specified in this code.
1.0.4 This code shall be used together with the current national standard "Unified Standard for Constructional Quality Acceptance of Building Engineering" (GB 50300).
1.0.5 The construction quality acceptance for timber structure work shall not only meet the requirements in this code, but also comply with those specified in the current relevant ones of the nation.
