Preparer: Signature of the construction worker

Reviewer: Signature of the company's chief engineer

They authorize it and just sign their names. The specification stipulates:

1. The construction unit shall be responsible for preparing the as-built drawings of the project. If the competent industry department requires the design unit to prepare or the construction unit entrusts the design unit to prepare as-built drawings, the review and signature approval responsibilities of the construction unit and supervision unit should be clearly stipulated.

2. If there are no changes during construction according to the construction drawings, the unit that prepares the as-built drawings will stamp and sign the completion stamp on the construction drawings.

3. General drawing changes and changes that meet the requirements for bar changes or demarcation changes can be made on the original drawings, with a completion stamp stamped and signed.

4. If it involves major changes in structural form, technology, layout, projects, etc. and if the area of ??the drawing changes exceeds 35%, the as-built drawing should be redrawn. The redrawing shall be numbered according to the original drawing, and the word "Complete" may be added at the end, or the "Completion Stage" shall be marked in the icon of the new drawing and the completion stamp shall be signed.

How to change as-built drawings

1. Changes to text and numbers are usually made by dashes; changes to lines are usually made by crossing out; for partial graphic changes, the changed parts can be circled and placed in the blank space of the original drawing. Redraw.

2. When making changes to construction drawings, the name, date, number and clause number of the document based on the change should be noted at the place of change.

3. If it cannot be expressed clearly on the drawing, it should be explained in text above or to the left of the title block.

The concept is that the as-built drawings are prepared using the original construction drawings. The original construction drawings are designed and the icons are from the design institute. The construction unit and supervision unit should sign and seal the as-built drawings. (1) The preparation of as-built drawings must be drawn by engineering and technical personnel;

(2) It must be prepared during the construction process and in conjunction with the project progress, and cannot be prepared after completion;

(3) The graphics, dimensions, structures, materials and relevant text descriptions reflected on the completed drawings must reflect the actual conditions after construction, so that the drawings, texts and actual objects are consistent, and there are no errors, omissions or ambiguities. place;

(4) As-built drawings modified using construction drawings must indicate the basis for modification, that is, the number of the design change order, drawing review record or material substitution order shall be indicated at the modification place;

(5) Construction drawings must be prepared in accordance with national architectural drawing standards or relevant professional standards and regulations;

(6) Changes to base maps and blueprints can only be made with scratches, not scratches. Correction fluid is allowed to be used to keep the drawings clean;

(7) Each as-built drawing must be stamped with a as-built stamp, or the as-built drawing icon must be redrawn.

(8) When using construction blueprints to prepare as-built drawings, new blueprints must be used, and old drawings that are worn, missing corners, or have grease stains on the construction site are prohibited from being used to prepare as-built drawings.

(9) The cover, drawings and catalog of the redrawn as-built drawings shall use the redrawn as-built drawing icon and no longer be stamped with the as-built seal; (10) All professional as-built drawings shall have a catalog of as-built drawings prepared , file the as-built drawings and place them in front of each professional drawing;
