Ministry of Construction of the People's Republic of China
November 1, 2001
According to the task assigned by the Ministry of Construction's Document No. 244 [1998] "Notice on Issuing the 1998 National Standard Formulation and Revision Plan for Engineering Construction (Second Batch)", the standard compilation team revised the "General Drawing Estimation" (GBJ103-87). The drafting team first proposed a draft for soliciting opinions with reference to the feedback collected in 1990, and widely solicited opinions from the whole country. Then, a draft for review was proposed, which was then approved by letter review and expert review, so that it has a good mass base.
The purpose of revising this standard is:
1. Coordinate and be consistent with the relevant national standards in "Technical Drawing" issued and implemented since 1990 (including the relevant standards of ISOTC/10) in terms of technical content. 2. Fully consider the respective characteristics of manual drawing and computer drawing, and take into account the needs of both and new requirements.
3. Modify, delete or supplement the legends, expressions and drawing rules that are not suitable for current use or are outdated to make them more in line with actual work needs. This standard is a recommended national standard.
The China Building Standard Design Institute is responsible for the specific interpretation of this standard. If there is a need for modification or supplementation during the application process, please send your opinions or relevant materials to the institute (No. 19 Chegongzhuang Street, Xiwai, Beijing, Postal Code 100044) for reference during revision.

Appendix: Explanation of clauses
1.0.1 In order to unify the general drawing drawing rules, ensure the drawing quality, improve the drawing efficiency, make the drawings clear and concise, meet the requirements of design, construction and archiving, and meet the needs of engineering construction, this standard is formulated.
This standard is applicable to drawings drawn by the following drawing methods: manual drawing;
computer drawing.
This standard is applicable to the following engineering drawings of general drawing specialty: general drawing of each stage of new construction, reconstruction and expansion engineering; general plan actual measurement drawing of original engineering:
General drawing and standard drawing of general drawing:
General drawing drawing, in addition to complying with this standard, shall also comply with the provisions of "Uniform Standard for Building Drawing" (GB/T50001--2001) and relevant mandatory standards currently in force in China.
2 General provisions
2.1 Drawing lines
2.1.1 The width of the drawing lines 6 shall be selected according to the complexity and proportion of the drawings and the relevant provisions of the drawing lines in "Uniform Standard for Building Drawing" (GB/T50001--2001). 2.1.2

1. Outline of planned expansion of buildings, structures, reserved land, railways, roads, bridges, culverts, enclosures, transportation facilities and pipelines
2. Flood inundation line
Invisible outline of existing buildings, structures, railways, roads, bridges, culverts and enclosuresBoundary line of open-pit mines and mining
Zero point line of earth filling and excavation area
Watershed line. Center line, symmetry line, positioning axis
underground mining area collapse boundary
disconnection boundary
Note: The different twisted and thin lines should be determined according to the key points indicated in the drawing. For example, when drawing the general plan, solid lines are used for new buildings, and center lines and thin lines are used for other parts; when drawing pipeline comprehensive diagrams or railway diagrams, thick solid lines are used for pipelines and railways.

2.2.2 One scale should be used for one drawing. Different scales can be used for longitudinal sections of railways, roads, earthworks, etc. in the horizontal and vertical directions. 2.3 Units of measurement
2.3.1 Coordinates and elevation distances in the general drawing should be in meters, and should be taken to at least two decimal places. If the scale is insufficient, it should be filled with "0". Detailed drawings should be in millimeters. If not in millimeters, it should be explained separately.
2.3.2 The azimuth (or direction) of buildings, structures, railways, roads, and the turning angles of railways and roads should be written to "seconds". In special cases, it should be explained separately. 2.3.3 The longitudinal slope of the railway should be calculated in dry points, and the longitudinal slope of the road, the slope of the site leveling, and the longitudinal slope of the bottom of the drainage ditch should be calculated in percentages, and should be rounded to one decimal place. If it is insufficient, it should be filled with \\. 2.4 Coordinate annotation method
2.4.1 The general plan should be drawn in the direction of north at the top and south at the bottom. According to the shape or layout of the site, it can be deflected to the left or right, but it should not exceed 45°. A compass or wind rose diagram should be drawn in the general plan (Figure 2.4.1).

Figure 2.4.1 Coordinate Grid
十009A
Note: In the figure, X is the north-south axis, and the increment of X is on the X axis; Y is the east-west axis, and the increment of Y is on the Y axis. A axis is equivalent to the X axis in the surveying coordinate grid, and B axis is equivalent to the Y axis in the surveying coordinate grid. 2.4.2 The coordinate grid should be represented by thin solid lines. The surveying coordinate grid should be drawn as a cross-line, and the coordinate code should be represented by "X, Y"; the building coordinate grid should be drawn as a grid line, and the coordinate code should be represented by \A, B\ (Figure 2.4.1). When the coordinate value is negative, the "+" sign should be noted. When it is positive, the "+" sign can be omitted.
2.4.3 When there are two coordinate systems, survey and construction, on the general plan, the conversion formula of the two coordinate systems should be indicated in the notes.
, 2.4.4 The coordinates indicating the location of buildings and structures should indicate the coordinates of their three corners. If the building or structure is parallel to the coordinate axis, the diagonal coordinates can be noted. 2.4.5 On a map, when the main buildings and structures are located by coordinates, smaller buildings and structures can also be located by relative size. 2.4.6 Buildings, structures, railways, roads, pipelines, etc. should be marked with the following parts: Position markings or positioning dimensions:
The positioning axis (or outer wall) of buildings and structures or their intersections: 1
The center of circular buildings and structures;
The center line of the belt corridor or its intersection;
The theoretical center of railway turnouts, the center line or turning point of railways and roads; 5
5The center line of pipelines (including trenches, pipe racks or pipe bridges) or their intersections: 6The outer edge line or turning point of the top of the retaining wall. The coordinates should be marked directly on the drawing. If there is not enough space on the drawing, they can also be marked in a list. 2.4.7
On a drawing, if the number of digits in the coordinates is too many, the previous identical digits can be added. 2.4.8
If the digits are omitted, the omitted digits should be explained in the notes. 2.5 Method of elevation annotation
2.5.1 The plane containing the soil elevation of 0.00 should be used as the general plan plane. 2.5.2 The elevations marked in the general plan should be absolute elevations. If relative elevations are marked, the conversion relationship between relative elevations and absolute elevations should be noted. 2.5.3 The elevations of relevant parts of buildings, structures, railways, roads, pipe trenches, etc. should be marked according to the following regulations:
1 For indoor floors of buildings, the elevation at 0.00 in the architectural drawing should be marked. For floors of different heights, their elevations should be marked separately (Figure 2.5.2a). 2 For outdoor scattered water of buildings, mark the elevation of the foot of scattered water slope at the corners or two diagonal corners around the building;
3 For structures, mark their representative elevations and indicate the position indicated by the elevation in words (Figure 2.5.2b);
