BIM standards must withstand market scrutiny and be open, practical, and forward-looking.
1) Public vs. Private Standards
Are the standards industry-wide or controlled by specific companies or groups? In recent years, China’s informatization efforts have revealed many challenges and lessons related to this issue. The openness and inclusiveness of standards are crucial factors that determine the vitality of Chinese BIM standards. Unfortunately, the construction industry in China has seen more setbacks than successes in developing information standards, largely due to these concerns.
2) National Standards vs. Local Standards
BIM standards should primarily be national standards. Local standards that conflict with national ones should be prohibited. However, in recent years, local regulatory bodies have introduced numerous local information standards to serve their own interests. This practice has seriously hindered the progress of informatization in the construction sector. For example, electronic bidding data interface standards and cost information data standards have been leveraged as tools by local authorities and manufacturers, resulting in significant industry losses. Consequently, companies often have to learn and purchase multiple types of software to participate in bidding and execute engineering projects across different regions.
3) Industry Advancement vs. Profit Motive
Informatization differs from design and construction standards, as it involves significant interests from various departments, enterprises, and manufacturers. Success depends on effectively managing these interests. The development of BIM standards is a matter of great importance to the industry, and its guiding principles must be clear and focused on genuine progress rather than mere profit.
