Notice on the Issuance of the "Unified Standard for Building Architectural Drawings"
Ji Biao [1986] No. 2614
According to the notice of the former State Construction Commission (81) Jianfa She Zi No. 546, the Ministry of Urban and Rural Construction and Environmental Protection, together with relevant units, revised the "Architectural Drawing Standards" GBJ1-73. The revised "Architectural Drawing Standards" are divided into six volumes, and the "Unified Standard for Building Architectural Drawings" is one of them, which has been reviewed by relevant departments. The "Unified Standard for Building Architectural Drawings" GBJ1-86 is now approved as a national standard and will be implemented from July 1, 1987. From the date of implementation of this standard, the relevant parts of the original "Architectural Drawing Standards" GBJ1-73 will be automatically abolished.
This standard is managed by the Ministry of Urban and Rural Construction and Environmental Protection, and its specific interpretation is the responsibility of the China Building Standard Design Institute. The publication and distribution work is organized by the Capital Construction Standard and Quota Research Institute of our Commission.

Revision Notes
This standard is compiled by the China Building Standard Design Institute of our Ministry together with relevant units in accordance with the "Notice on the Compilation and Revision Plan of National Standards and Regulations for Engineering Construction from 1983 to 1985" No. 546 of the former State Construction Commission's "81" Jianfa Shezi.
This standard is compiled on the basis of the original architectural drawing standard (GBJ1-73), with the necessary modifications and supplements to the common parts of each profession, and renamed "Unified Standard for Building Architectural Drawing". The professional drawing standards for each professional part of the original standard have been compiled separately by profession. This standard should be used in conjunction with various professional standards. During the revision process, this standard carefully summarized my country's practical experience, combined with my country's actual situation, and actively adopted international standards: drawing specifications, lines, fonts, proportions, axis numbers, projection methods, dimension annotation methods, etc. are basically consistent with international standards, and microfilm requirements are taken into account, which basically meets the current domestic technical level. On the basis of extensively soliciting opinions from relevant design, construction, scientific research and colleges and universities across the country, our department will review and finalize the draft together with relevant departments.
This standard is divided into ten chapters and four appendices. Its main contents include: general principles, drawing format specifications and drawing arrangement order, lines, fonts, proportions, symbols, positioning axes, common building material legends, drawing methods, dimension annotations, etc. In the process of implementing this standard, please combine engineering practice, carefully summarize experience, pay attention to accumulating information, and if you find that there is a need for modification and supplementation, please send your opinions and information to the China Building Standard Design Institute for reference during revision.
