The goal of optimizing design standards is to enhance the quality of architectural design institutions. When BIM is not essential, the focus should be on establishing robust CAD standards and applying them effectively. CAD standards help standardize design processes, ensure design quality, and improve collaboration within architectural design firms. From a BIM user’s perspective, design standards build upon CAD standards. Therefore, promoting the development and application of BIM standards is crucial to facilitate the successful implementation of BIM functionalities.
CAD Drawing Management Standards
Regarding CAD standards, the United States defines them as guidelines that facilitate data sharing throughout a project’s entire lifecycle. These standards help coordinate design data for building projects, promote communication among stakeholders, reduce project costs, and positively impact design and construction quality.
China has also established regulations for CAD standards, suggesting that engineering drawings should be created with computers following these guidelines. These standards specify requirements for setting parameters, drawing methods, projection techniques, and graphic symbol representation. However, they lack detailed provisions on file naming conventions and folder structures. As a result, CAD standards are not fully implemented in practice.
Typically, CAD standards encompass the following six areas:
- 1. CAD Layer Specifications
- 2. File Naming Conventions
- 3. CAD Drawing Specifications
- 4. Text Style and Font Specifications
- 5. Drawing and Reference Document Standards
- 6. Folder Structure Specifications
BIM Information Management Standards
BIM research originated in the United States, making its BIM technology more advanced than that of other countries. The U.S. first published BIM standards in 2007, inspiring other developed nations to release their own BIM standards over time.
Currently, two primary types of BIM standards are widely used: implementation standards and technical standards. BIM implementation standards are based on technical standards and are designed to standardize the development and management of BIM applications, ensuring compatibility among BIM-related systems.
The technical standards for BIM cover three main aspects:
- 1. Data Storage Specifications
- 2. Information Transmission Specifications
- 3. Information Semantic Specifications
BIM implementation standards are operational guidelines developed based on technical standards and real-world practices. These often take the form of operation manuals or user guides. Since building activities vary across countries and regions, the types of standards also differ accordingly.
China is increasingly focusing on developing BIM standards. In the author’s opinion, China’s BIM standards currently serve as reference standards, helping project participants understand the BIM technical standard system and enabling BIM to fully realize its potential.
