In project management, how should as-built drawings be managed, and how can consistency among drawings from different specialties as well as consistency in their names, numbers, and content be ensured?

As the title suggests, production has been stable recently, and with nothing much to do, I’ve been looking through the as-built drawings to facilitate future technical upgrades and emergency repairs. I found that some of the as-built drawings prepared by well-known domestic design firms are completely unreadable – they lack care and precision. The quality of these drawings is totally inconsistent with the reputation of those firms. The problems are as follows: 1. The names and numbers in the table of contents do not match those of the drawing titles, numbers, or content. For example, in the table of contents, drawing number 1503 is labeled as the “Sewage Oil System Diagram,” but in the actual drawing, it’s titled the “Nitrogen System Diagram”; meanwhile, the label in the lower right corner reads “Gas System Diagram,” while the content of the drawing actually depicts a “circulating water system.” 2. In the as-built drawings, the drawings related to process engineering and installation work do not match. For instance, process engineering diagrams show blowdown lines, but these lines are not present in the installation drawings or on-site. This inconsistency leads to the following problems: 1. It’s difficult to use or locate the correct drawings. If one tries to find the sewage oil system diagram, what is found is actually the nitrogen system diagram, and upon closer inspection, it turns out to be a circulating water system diagram. 2. Most importantly, technical upgrades and modifications are carried out based on the previous version of the as-built drawings. If there’s a discrepancy between the as-built drawings and the actual site conditions, it becomes impossible to carry out these upgrades using proper drawings. I would like to ask everyone: 1. In project management, how can such issues be prevented regarding the management of drawings? 2. How is everyone’s drawing management handled? 3. Before being archived, who is responsible for reviewing the as-built drawings, and how is it ensured that the process-related drawings are consistent with the installation drawings, and that the installation drawings correspond to the actual construction conditions on site? 4. If there are many instances of inconsistencies, how do people remedy them and make corrections? Fixing the mistakes after they’ve occurred is also a form of improvement, right?

At the beginning, it is necessary to standardize the project names, directory names, and the corresponding drawing names, with repeated checks being done later as well. The inter-disciplinary review process must be carried out properly, and the coordination with the site should, as much as possible, take into account on-site experience.

This design institute is really unacceptable; every institution has rules for numbering drawings, but it’s unclear how they conduct reviews

If such problems arise during the construction and installation phase, it is possible to request the design institute to make changes

Well then, let’s take a look at the completion status on site; the site can’t possibly be inconsistent, right?

In the table of contents, the name corresponding to drawing number 1503 is \"Sewage Oil System Diagram\"; whereas in the main text, the file name for drawing number 1503 is \"Nitrogen System Diagram\". However, the title at the lower right corner of the drawing reads \"Gas System Diagram\", and the content depicted in the drawing itself refers to \"circulating water\". For drawing number 1503, the corresponding item on-site can only be one of these four options, right?

So where can I find the diagram of the sludge oil system I need?

I guess a substitution has been made! It’s not the same person who did the design; the situation is unclear, so only what is known has been changed. Moreover, for the as-built drawings, the contractor is responsible for preparing the boundary lines, and the designer then creates the drawings based on those boundary lines.

Are there any files such as pipeline ISO diagrams or Line Lists?
