Completion document service is not just a simple filing after the project is completed. It is a series of professional activities that require accurate recording and digital management of the actual built facilities, systems and all changes after the construction is completed. This record showing the "final state" is the only reliable basis for the operation, maintenance, transformation and safety of the assets in the next few decades. In the industry, there are common problems of incomplete data, many errors, and untimely updates, which directly leads to high maintenance costs and safety risks in the later period.
Why traditional as-built documents are so full of errors
The traditional method of producing as-built documents based on two-dimensional CAD drawings has natural and unavoidable flaws in real situations. In electrical engineering and similar fields, a single device or component may appear on as many as 20 different drawings. Once a change occurs on site, the draftsman must update all related drawings by hand. Such a "one-to-many" correspondence is extremely prone to omissions and errors.
At the same time, deadlines and cost pressures often result in incomplete or hasty completion documents submitted by contractors. Information about changes is often simply marked on some drawings, rather than systematically updated at all involved locations. Such a decentralized and manual workflow results in varying quality of documents that are ultimately archived, posing great hidden dangers to subsequent management.
What specific contents and forms do the completion documents contain?
Far more than just drawings, it is a complete package of as-built documents. For a transportation project, this may include key drawings, signature pages, typical sections, bill of quantities summary, floor plans, cross-sections, and wiring schematics. The core is to record all deviations from the original design intent during the construction process.
This covers all approved change orders, including field instructions, as well as responses to requests for information and clarification documents. The form of records is no longer limited to paper-style blueprints. Electronic CAD files, PDF documents and even higher-dimensional information models are becoming standard deliverables. The goal is to build a unified recording system that accurately reflects the "as-built status".
What are the real risks of inaccurate as-built documentation?
The primary risk posed by inaccurate completion documents is personnel safety. If workers carry out maintenance or upgrade operations based on drawings that are inconsistent with the site, they may accidentally touch live equipment or misunderstand system configurations, which may lead to serious safety accidents. The head of the Western Power Administration, or WAPA, has made it clear that the organization must bear unshirkable responsibility for workers being injured due to reliance on incorrect drawings.
This presents high operating costs and losses in efficiency. Asset managers have to spend a lot of time searching for drawings in the storage room or verifying information on site, which greatly affects maintenance efficiency and decision-making speed. In addition, when planning a new project, inaccurate information on existing facilities can lead to design errors, cost estimates, and even contract disputes.
What are the common challenges currently faced by the industry in managing as-built documents?
The challenges faced by the industry are universal. First of all, there is a "backlog" of massive historical drawings. Many organizations have tens of thousands of drawings drawn by different contractors at different times and according to different standards. However, these drawing standards lack consistency and lack of continuous update mechanisms. As a result, no one dares to confirm their accuracy. Clearing this historical backlog is a difficult task.
There is a lack of uniformity and efficiency in the management process. Many public agencies lack the resources to produce detailed and accurate as-built drawings. Collaboration between departments is not smooth. The "constantly interrupted" work mode affects the timeliness and continuity of drawing updates. There is no central repository and standardized guidelines, which further aggravates the information chaos.
How to systematically improve and produce high-quality as-built documents
A systematic plan is needed to achieve improvement, and the first step is to establish standardized processes and specifications, clarify the drawing structure, numbering rules, equipment identification, and a closed-loop management process from change to drawing update, and set up liaisons for developers and users of as-built documents to effectively coordinate the needs of both parties.
It is critical to ensure that updates are carried out "as a companion" rather than as a centralized catch-up after the project is completed. It is recommended to continuously update completion information and use mobile devices such as iPads and simple editing software throughout the project. At the same time, all final completion documents are stored in a central location that is centrally accessible to all stakeholders. This is the basis for ensuring information consistency.
In what direction will as-built document services develop in the future?
The future development trend is all-round digitization and intelligence. Document service systems that work on cloud platforms are booming. They can achieve unified monitoring, management and efficient utilization of a huge number of drawing resources. The more essential change is the transformation from two-dimensional CAD to object-oriented three-dimensional modeling technology such as system information models.
As an extension of Building Information Modeling (BIM) at the system level, SIM can fundamentally solve the problem of duplication and inconsistency of component information in multiple drawings. It is bidirectionally associated with the physical model. Modifications made in one place will be updated everywhere, which greatly improves the integrity and quality of documents. At the same time, automated processing tools have also begun to be applied. By ensuring the format and quality of submitted data, manual processing time that originally took weeks can be shortened to a few hours. For example, global procurement services for low-voltage intelligent products, which integrate supply chain information and digital deliverables, may also become part of the future completion data package.
As far as the organization you are in is concerned, what is the most prominent pain point encountered in facility operation and maintenance or project management due to inaccuracies in drawings or data? Will it affect construction safety, affect maintenance efficiency, or cause problems with new project planning costs? Feel free to share your experiences in the comment area.
