Who prepares the as-built drawings

Why must the as-built drawings be prepared by the design firm? - Powered by Discuz! http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1360517

First of all, it should be clear that the completion inspection is organized by the construction unit, which is responsible for apposing the completion stamp. But the construction company cannot prepare the drawings, so the drawings still need to be created by a design firm. However, one thing is clear: if the construction party follows the drawings exactly, they can directly stamp the completion mark on the construction drawings; if there are any changes, a design change order should be attached along with the completion mark. If the changes are too large. Have the design firm prepare the as-built drawings, and have the construction party affix the as-built stamp.

The as-built drawings are the responsibility of the construction contractor; generally, modifications are made to the original design drawings. However, if the extent of the modifications exceeds a certain percentage, the contractor is required to prepare new drawings. The as-built drawings must bear the as-built drawing seal of the construction unit, and must be reviewed and signed by the supervisor

The specifications for SH clearly require them to be prepared by the design institute.

The old specification required it to be completed by the construction unit, as stated on floor 4. In the technical documentation requirements for the completion of the SH3503 petrochemical construction project in 2007: 6.1.2 The preparation, review, and compilation of technical documentation for the completion of construction projects shall comply with the following provisions: a) The design unit is responsible for preparing the as-built drawings ； b) The construction contractor is responsible for preparing the handover technical documents for the construction scope specified in the contract ； c) The testing unit is responsible for preparing the non-destructive testing reports and other inspection and test reports within the scope of the contract or the assigned tasks ； d) The entity responsible for purchasing the materials and equipment is tasked with compiling the quality certification documents for such materials and equipment within the scope of the contract ； e) For projects under EPC, the EPC contractor is responsible for reviewing and compiling the technical documents submitted by each subcontractor for project handover ； f) The supervision unit is responsible for reviewing the handover technical documents. 6.2.8 The preparation of as-built drawings for construction projects shall comply with the following provisions: a) If construction is carried out in accordance with the original plans without any changes, the original detailed engineering design documents can be used as the as-built drawings ； b) As-built drawings shall be prepared based on the final revised conditions in case of design changes during construction ； c) Once the as-built drawings are completed, they should be stamped with the as-built drawing stamp (see Figure 1). The stamping location should be in the blank space above the title bar of the drawings, and it should be signed off by the supervision unit. The signature fields in the completion certificate are respectively: design unit, preparer, reviewer, date; supervision unit, on-site supervisor, chief supervisor, date – it has nothing to do with the construction unit either.

How is this ratio controlled? Is there a limit?

The design unit is required to complete it, while the construction unit is responsible for organizing it

Since the contracts for construction, design, supervision, etc. are all signed with the project owner, the construction company does not have to pay other entities; therefore, its organization lacks binding force, or in other words, it has neither the right nor the obligation to do so. The general contractor represents another case; however, by signing a contract with the project owner, the general contractor essentially acts on behalf of the owner in carrying out some of their duties.

I think we should follow the suggestions of the colleague from that building
