Content change: (1) for the change of numbers, symbols and words, the cancelled content can be marked off on the drawing with the bar change method, the corrected content shall be added in the blank space near it, and the basis for modification shall be indicated.
All changed parts must be led and the change basis must be indicated; for modification on the construction drawing, it is not allowed to modify the drawing paper by smearing with correction fluid, scraping, subsidy and other methods.
if there is no change in the preparation requirements of as built drawings during construction, the preparation unit shall affix and sign the as built seal in the blank near the signature of construction drawings; If there is any general drawing change, it shall be directly redrawn on the construction drawing, stamped with the completion seal and signed; If the structural form, process, layout, etc.
Additional contents: (1) If partition walls, doors and windows, lamps, equipment, reinforcement, etc.

(3) if a part of the drawing changes greatly, or it is difficult to redraw in the original position, or it is disorderly after redrawing, the following methods can be used for redrawing: draw supplementary Drawings, modify and redraw the detail drawing of the as built drawing.
Completion acceptance data is the data formed in the project completion acceptance activities, including project acceptance summary, completion acceptance records, financial documents, audio-visual, microfilm, electronic archives, etc.
Add instructions: (1) When the model change of a certain equipment, door and window on the drawing involves multiple modifications, all involved places shall be modified, and the modification basis can be marked at one modification place, but a brief description must be made here.

are added to a certain part of the building, they shall be drawn in the actual position on the drawing with the standard drawing method, and the modification basis shall be indicated.
shall be redrawn on the original drawing.
For local modification, the changed parts can be circled and the changed contents can be drawn in the blank of the original drawing.
The specific modification method can be seen from the actual situation such as the drawing surface, change scope and position, complexity and simplicity, etc It depends.
(3) for the negotiation records involving the description type, the design specification terms shall be used on the corresponding drawings to reflect the negotiation contents.

All involved drawings shall be modified according to the regulations, not only one but not the other; 4) the design change or engineering negotiation record and attached drawings shall not be pasted or attached to the as built drawings as modification, nor The contents of design changes or engineering negotiation records may be copied on the blueprint as modifications; 5) When it is necessary to redraw the as built drawing according to the regulations, the drawing shall be made according to the requirements of drawing the as built drawing..
(2) the cancellation of partition wall, door and window, reinforcement, lamps and equipment can be carried out by the cross modification method.

Preparation of as built drawings I.
The as built drawings are the engineering drawings that reflect the reality of the completion of the construction project after the completion of the construction project, and are the technical documents that truly record the conditions of various aboveground and underground buildings and structures.
(2) When it is difficult to express the changes such as the replacement of reinforcement, the change of concrete strength grade, the change of wall, slab and internal and external decoration materials clearly by graphic method, it can be annotated or explained in the form of index.

1、 Cancellation contents: (1) the cancellation of numbers, words and symbols such as size, door and window model, equipment model, lamp model, reinforcement model and quantity, annotation and description can be carried out by the bar modification method.
Abstract: when preparing as built drawings, the drawing catalogue of as built drawings of various disciplines must be prepared, and the as built drawings must be accurate, clear, complete and standardized, which can truly reflect the actual situation after the completion of the project; The drawings used to change the as built drawings must be the white drawings drawn by the new blueprint or plotter, and the copied drawings shall not be used.
Precautions: (1) The catalogue of construction drawings must be stamped with the as built seal and filed as the as built drawings; all obsolete, supplemented, added and modified drawings shall be clearly marked on the catalogue of construction drawings, that is, the obsolete drawings shall be carried off on the catalogue, and the supplemented drawings shall list the drawing name and drawing number on the catalogue; (2) If a construction drawing changes greatly and the design unit redraws the modified drawing, the modified drawing shall replace the original drawing, and the original drawing will no longer be archived (3) A design change or engineering negotiation record may involve two or more drawings, and a local change may cause system change.
Generally, the as built drawings are redrawn on the construction blueprint by using the “as built” bar (marking) modification and cross modification.
(2) if the added content is unclear in the original position, the detailed drawing shall be added at the appropriate position (blank space) of this drawing as required (detailed drawing); if there is no position to be drawn on the drawing, the supplementary drawing shall be drawn with sulfuric acid paper and dried into a blueprint, or the white drawing shall be drawn with a plotter and attached to the professional drawing.

are significantly changed or the changed part exceeds 1 / 3 of the drawing surface, the as built drawing shall be redrawn, and the redrawn drawing shall be stamped with the as built seal and signed; When preparing as built drawings, the drawing catalogue of as built drawings of each discipline must be prepared, and the as built drawings must be accurate, clear, complete and standardized, which can truly reflect the actual situation after the completion of the project; The drawings used to redraw as built drawings must be new blueprints or white drawings drawn by plotters, and copied drawings shall not be used; The as built drawing preparation unit shall draw the as built drawing in accordance with the requirements of the national architectural drawing specification, and use the drawing pen or signature pen and non fading drawing ink.
