How to draw as-built drawings

Question 1: What should you pay attention to when drawing as-built drawings and how to draw them? 1. Basic requirements for the preparation of as-built drawings

1. As-built drawings should use new or clean construction drawings, and be stamped and signed with a completion stamp as required.

2. If the construction is carried out according to the drawings and there are no changes, the "as-built drawing" mark can be stamped on the original construction drawings.

3. If there are general design changes that can be modified or supplemented on the original construction drawings, the construction unit shall indicate the modification content and basis for the modifications on the original construction drawings (must be new blueprints) and use them as as-built drawings.

4. After there are major changes in the structural form, process, layout, projects, etc. and the drawing area changes by more than 35%, the as-built drawing must be redrawn. The repainted drawings are numbered according to the original drawings, with the word "Jun" added at the end. The new drawing icon should indicate "Complete

Stage".

5. The as-built drawings should be accurate, clear, complete, standardized, revised in place, and truly reflect the actual situation at the time of completion acceptance. The quality of the drawings must be ensured, the specifications must be uniform, the drawings must be clean and the writing must be clear. Ballpoint pens or other inks that are easy to

fade may not be used for drawings.

6. After the preparation of as-built drawings is completed, the supervision unit shall supervise and assist the design and construction units to check the preparation of as-built drawings.

If inaccuracies or shortages are found, they shall be modified and completed in a timely manner.

7. The content of the as-built drawings should be consistent with the construction drawing design, design changes, material changes, actual construction conditions and quality inspection records.

8. Provide general instructions for preparing as-built drawings and preparation instructions for each major, describe the principles for preparing as-built drawings, catalog of each major and the preparation situation.

9. The as-built drawings are folded into A4 drawings (210mm×297mm) according to the "Folding Method of Technical Drawing Reproduction Drawings", and the icon is exposed.

Question 2: How to draw the as-built drawing of the building? It is simple to say: first understand the truth: the as-built drawing is to draw what the construction unit has already done.

1. Get the electronic version of the design drawings.

2. Collect all design changes.

3. Modify the original design drawings according to the design changes.

4. Key point~! It must indicate the unconstructed part~! ! For example, the post-factory pouring tape, or the part where construction is planned to be delayed. This is very important, otherwise it will be a joke.

(This corresponds to the sentence above "draw what has been done". The unfinished parts must be clearly marked)

5. Do not change anything else. Because in theory, the construction is based on the drawings, and what you make is what you originally drew, and there shouldn't be anything different.

4. Hydropower drawings are a matter for the hydropower major, and you cannot do it unless your leader is 290.

5. Check the drawing carefully. The actual drawing will not take long, the key is to be careful.

I wish you success~!

Supplementary answer: In theory, as-built drawings should be drawn at the time of completion. In practice, when the owner's delivery requirements are met, that is, when the completion acceptance is ready to begin, the as-built drawing must be drawn - the as-built drawing is an item of the completion acceptance.

In addition, as-built drawings, like construction drawings, are divided into structural installations, construction installations, water installations, etc.

Question 3: Who should draw the as-built drawings? As-built drawings should be drawn by the construction party, and it should be clear that this is not the scope of the designer's services.

If the construction party does not have the ability and needs you to draw as-built drawings, it should be required to provide drawings of construction changes and other corresponding materials, and a certain fee will be charged to it. The amount of the fee shall be negotiated by both parties. The as-built drawings should be stamped with the completion stamp of the construction unit, not the design unit.

Question 4: How to draw the as-built drawing of the project~Help! ! ! Basically, there is no need to do anything. Just modify the construction drawings according to the on-site construction conditions, and reflect any changes and additional items.

Question 5: How to draw as-built drawings 1. Use the construction blueprint to modify the as-built drawing. On the construction blueprint, the dash (cross) and cross modification methods are generally used; for local modifications, the changed parts can be circled and placed on the original drawing. Draw the changes in the blank space; all changes must be indexed and the basis for the changes must be indicated. The specific method of changing the drawing depends on the actual situation such as the visual plane, the scope and location of the change, the degree of complexity and simplicity, etc. (1) To cancel or change design content A, dimensions, door and window models, equipment models, lamp models, steel bar models and quantities, annotations, and other numbers, text, and symbols, the bar change method can be used. Use horizontal bars to cross out the numbers, words, symbols, etc. that are about to be cancelled. Draw an index line with an arrow from the modified position, and indicate the basis for the modification on the index line, for example, "See the design change notice of × year × month × day, × layer Z15 (Z16) column section in the structural diagram (Knot 2), (Z16) is cancelled." B. To cancel partition walls, doors, windows, steel bars, lighting fixtures, equipment, etc., the cross modification method and the bar modification method can be used. For example, if the ⑧ axis partition wall on the 6th floor is cancelled, you can put an "×" on the position of each wall; if you want to change the window C602 to C604, you can put a "bar" on the door and window model and related dimensions, (C602) and then on the other The "bar" is marked with C604, and an arrow index is used to point out the modification point, and the basis for the modification is indicated. (2) Adding and changing design content. Adding partitions, doors, windows, lamps, equipment, steel bars, etc. to a certain part of the building should be drawn on the drawing, and the basis for modification should be indicated. The drawing modification method can be to draw the added steel bars at the required positions of the section and indicate the basis for the change. (3) When a certain part of the drawing changes greatly, or it cannot be modified at the original position, the method of drawing a large sample or using additional drawing paper can be used. A. How to draw large-scale drawings. After marking the range of the parts that should be modified on the original drawing, draw a large sample of the modified parts in the blank space, and indicate the basis for the modification in the changed range and large sample of the original drawing. B. Method of supplementing drawing paper. If there is no blank space in the original drawing, you can use sulfuric acid paper to fill in the drawing and dry it into a blueprint, or use a plotter to draw a white drawing and attach it to the original drawing. The basis for the modification should be indicated on both the original modified location and the supplementary drawings, and the supplementary drawings should have the drawing title and drawing number. Specific method: Draw the scope of modification on the original drawing, and indicate the basis for the modification and a certain drawing (indicate the drawing number and title); the drawing number and title must also be noted on the supplementary drawing, and indicate that it is the original drawing. The basis for supplementing and modifying a certain part of a certain drawing (indicate the drawing number and title). 2. Redraw the as-built drawing. If it is necessary to redraw the as-built drawing, it must be drawn and prepared in accordance with the relevant drawing standards and the requirements of the as-built drawing. (1) The redrawn as-built drawing is required to be in the same proportion as the original drawing, and should also comply with relevant drawing standards, have a standard drawing frame and a complete drawing label, and be stamped with a completion stamp. (2) As-built drawings drawn with CAD should be modified based on the design changes and project negotiation content on the electronic version of the construction drawing. After modification, use a cloud diagram to circle the modified parts, and make a modification preparation sheet in the blank space of the drawing, and The drawing must be signed by the original designer. 3. Use the scraping method to draw on the original sulfuric acid paper according to the design changes, engineering negotiations, etc., that is, use a blade to scrape off the parts that need to be changed, then use a drawing pen to draw the modification content, and make a modification preparation sheet in the blank space of the drawing. , indicate the changes, negotiation number (or time) and modification content, and make a blueprint. 4. Add instructions to as-built drawings (1) Any design changes or negotiation contents that are modified on the construction drawings should be redrawn on the blueprints using the drawing method without adding instructions. If there are still contents that cannot be expressed in the revised drawings Be clear and appropriately explained in concise language. (2) When the change of a certain equipment, door factory, etc. model on the diagram involves multiple modifications, all involved places must be redrawn. The basis for the modification can be noted in one modification, but it needs to be done here. Simple explanation. (3) Replacement of steel bars, changes in concrete strength levels, changes in walls, boards, interior and exterior decoration materials, and parts that are handled by the construction unit itself, etc. If the modification on the drawing is difficult to express clearly using the drawing method, you can add or Explain in the form of an index. (4) For any negotiation involving descriptions, design specification terms should be used in the corresponding drawing description to reflect the content of the negotiation.

Question 6: How to draw the completed drawing of architectural decoration? 1. If the construction is carried out strictly according to the design, a completion stamp will be stamped on the original drawing and it will be deemed as a completion drawing.

2. If there are general changes, but the original construction drawings can be modified and supplemented to reflect the actual completion, it is not necessary to draw new as-built drawings, and the construction unit will make supplementary modifications in accordance with the methods stipulated in the change documents. Afterwards, a completion stamp is stamped and deemed as a completion drawing.

3. Any changes in structural form, process, floor layout, project changes and other major changes or if the changed part exceeds 1/3 of the drawing, the as-built drawing should be redrawn

Question 7 : How to draw as-built building drawings and what materials are needed 1. Five new sets of blueprints are required.

2. Draw the contents of the change order and the technical approval order into the new blueprint.

3. It is required to draw pictures with index symbols.

4. Usually painted with black pen.

5. A completion stamp is also required, and the size is required. You can buy this kind of book at the archives.

Question 8: How to draw as-built drawings It’s easy to say: first understand the truth: as-built drawings are to draw what the construction unit has already done.

1. Get the electronic version of the design drawings.

2. Collect all design changes.

3. Modify the original design drawings according to the design changes.

4. Key point~! It must indicate the unconstructed part~! ! For example, it is the post-casting belt, or the part where construction is planned to be delayed. This is very important, otherwise it will be a joke.

(This corresponds to the sentence above "draw what has been done". The unfinished parts must be clearly marked)

5. Do not change anything else. Because in theory, the construction is based on the drawings, and what you make is what you originally drew, and there shouldn't be anything different.

4. Hydropower drawings are a matter for the hydropower major, and you cannot do it unless your leader is 290.

5. Check the drawing carefully. The actual drawing will not take long, the key is to be careful.

Question 9: How to draw the as-built drawing of the project? What pictures do you draw? The as-built drawings are the original complete set of construction drawings that have been modified and drawn according to the actual construction! It includes many things, the most important one is the water and electricity area, which is the wiring diagram, the water pipe distribution diagram, and the system diagram (mainly indicating where the water valves are and how to control the electric box switch), because the water and electricity area is the most important to repair. , so Party A will pay special attention to it. It's not that important like other things. If there is a change contact sheet, just change it!

Question 10: How to draw as-built drawings for decoration. If the design changes and there are changed drawings, the company will have to find a specialized person to make a budget for the as-built drawings. This budget must be linked to the company's profits. After they have finished it, they will submit it to Party A for review. Party A will then settle the project payment for you after verification.

Therefore, the dimensions of the as-built drawing must be measured on site. It is best to draw a new as-built drawing based on the original design drawings and modification drawings, and do not change the dimensions on the design drawings. Because people who make estimates usually use commands to calculate the project quantities on the CAD software drawings. If you only change the dimensions but do not actually change the specific dimensions of the drawings, the error will be huge. Party A may not be able to review it, and the project payment will be difficult. Get it. If you are familiar with CAD, the as-built drawings will be drawn quickly. Don’t be afraid of trouble when doing the project.
