As-built drawing is a drawing drawn by the construction unit according to the actual construction situation when it is completed, because it is inevitable to be modified during the construction process. In order to let the construction unit or user know more clearly the actual direction of the pipeline and the actual installation of the equipment, the state stipulates that the construction unit must submit the completion drawing after the project is completed.
The requirements of as-built drawings are mainly reflected in the following fourteen items:
A, as-built drawings should use new or clean construction drawings, and stamped and signed as required.
Second, if there is no change in the construction according to the drawings, the "as-built drawing" sign can be stamped on the original construction drawing.
The third is the general design change, which can be modified and supplemented on the original construction drawing. After the construction unit registers and modifies the contents and basis on the original construction drawing, it shall be regarded as the as-built drawing.
4. Post-structure form, technology, plane layout, project, etc. Major changes have taken place and the map change area exceeds 35%, and the as-built map must be redrawn. The redrawing should be numbered according to the original drawing, and the word "Jun" should be added at the end. Icons on new drawings should indicate "completion stage".
Fifth, the as-built drawings should be accurate, clear, complete, standardized and revised in place, and truly reflect the actual situation at the time of completion acceptance. To ensure the quality of drawings, the specifications should be uniform, the drawings should be neat and legible, and drawings should not be drawn with ballpoint pens or other fading inks.
Sixth, after the completion of the as-built drawing, the supervision unit will urge and assist the design, and the construction unit will check the preparation of the as-built drawing. If it is found to be inaccurate or missing, it should be revised and supplemented in time.
Seventh, the contents of as-built drawings are consistent with the construction drawing design, design changes, material changes, actual construction conditions and quality inspection records.
The eighth is to compile the general description and professional description of the as-built drawings, and describe the compilation principles, professional catalogues and compilation conditions of the as-built drawings.
Ninth, the as-built drawing is folded into A4 paper according to the folding method of technical reproduction drawing, and the icon is exposed.
10. As-built drawings shall be prepared in parallel at the unit price, with detailed descriptions and contents, and marked with page numbers.
Eleventh, as-built drawings are arranged by specialty and drawing number.
Twelfth, the quality and arrangement of as-built drawings should be detailed in the contents of the self-inspection report.
Thirteenth, according to the requirements of the owner, the number of sets of as-built drawings is compiled in quadruplicate, of which the construction unit keeps one set for itself.
14. All as-built drawings shall be kept permanently.
Requirements for completion stamp:
1. The "as-built stamp" shall be marked with the words "as-built drawing", and include the basic contents such as the name of the compiling unit, the compiler, the reviewer, the technical director, the compiling date, the supervision unit, etc. The responsible persons of all parties shall be responsible for the as-built drawings.
2. All as-built drawings shall be stamped with the as-built stamp by the preparation unit one by one, and signed by the responsible persons of all parties. The signature in the completion stamp must be complete, and signature is not allowed.
3. All as-built drawings prepared by the design unit must be marked as the completion stage in the design countersignature, and signed by the draftsman and technical director.
4. The completion stamp shall be affixed to the blank space near the drawing mark.
5. As-built stamp shall use indelible red or blue inkpad.
