About approving the "General Plan Drawing Standard" and other four drawing standards as national standards
Standard Planning [1987] No. 966
According to the notification of the former State Construction Commission (81) Jianfa Shezi No. 546, the Ministry of Urban and Rural Construction and Environmental Protection, together with relevant departments, revised the "Architectural Drawing Standard" GBJ1-73 sub-professions and completed the revision of four parts including the general plan. After review by relevant departments, the revised General Drawing Standard GBJ103-87, Architectural Drawing Standard GBJ104-87, Architectural Structure Drawing Standard GBJ105-87 and Water Supply and Drainage Drawing Standard GBJ106-87 are now approved as national standards and will be implemented on January 1, 1988. The relevant parts of the original Architectural Drawing Standard GBJ173 will be abolished at the same time. The four standards are managed by the Ministry of Urban and Rural Construction and Environmental Protection, and the specific interpretation and other work are the responsibility of the China Building Standard Design Institute. The publication and distribution is organized by the Basic Construction Standard and Quota Research Institute of our Commission.

Revision Notes
This standard is compiled by the China Building Standard Design Institute in conjunction with relevant units in accordance with the notice of the former State Construction Commission (81) Jianfa Shezi No. 546. This standard is compiled on the basis of the original "Architectural Drawing Standard" GBJ1-73, and the content of the original standard structure specialty is revised and supplemented. During the revision process, this standard carefully summarized my country's practical experience, combined with my country's actual situation, actively adopted international standards, and widely solicited opinions from relevant design, construction, scientific research and colleges and universities across the country. Finally, it was finalized after review by relevant departments. This standard is divided into five chapters and two appendices. The main contents are: general principles, general provisions, reinforced concrete structure, steel structure, wooden structure, common component codes, etc. This standard should be used in conjunction with the "Uniform Standard for Building Architectural Drawing". In the process of implementing this standard, all units are requested to combine engineering practice, carefully summarize experience, and pay attention to accumulating data. If any modification or supplement is found, please send your opinions and data to the China Building Standard Design Institute for reference during revision.

Chapter 1 General
Article 1.0.1 This standard is formulated to make the drawing of building structures basically unified, clear and concise, improve the drawing efficiency, meet the requirements of design, construction, archiving, etc., and adapt to the needs of engineering construction.
Article 1.0.2 This standard applies to the following engineering drawings of building structure specialty: 1. Design drawings and completion drawings of each stage of new construction, reconstruction and expansion projects; 2. Measured drawings of existing buildings, structures, general drawings, etc.; 3. General drawings and standard drawings.
Article 1.0.3 In addition to complying with the provisions of this standard, building structure drawings shall also comply with the provisions of the "Uniform Standard for Building Drawings" and the relevant standards and specifications currently in force in the country.
