In the domestic construction industry, BIM technology is primarily valued during the design and construction stages, with fewer applications spanning the entire project lifecycle. BIM implementation can generally be categorized into three modes: design-led, construction-led, and owner-led.
1. Design-led Mode
BIM software enables the creation of three-dimensional project models, and its intuitive, visual nature was first embraced by designers. Using core and geometric modeling tools, designers can craft complex surface shapes, fully express design concepts, and showcase architectural forms. The model data also supports scheme analysis, significantly reducing repetitive modeling efforts.
For design firms, leveraging BIM technology for 3D design not only boosts design efficiency but also allows them to comprehensively present renderings and detailed plans to clients, enhancing their competitive edge.
Although the design-led mode is widely used, its scope is limited to the design phase, and the generated data and models often do not support subsequent project stages.
2. Construction-led Mode
In the construction-led mode, BIM applications focus primarily on the construction phase.
For construction companies, BIM technology offers key advantages in two main areas: first, during the bidding phase, BIM-based construction simulations enhance visualization, effectively communicating construction organization and management methods, thereby increasing the chances of winning bids. Second, during project execution, virtual construction enables optimization of site layout and construction plans, early identification and resolution of issues, reduction of unnecessary rework, and the ability to present the construction process through animations or videos to owners and teams. This greatly improves communication and collaboration.
By integrating BIM models with on-site conditions, the construction process becomes more transparent and manageable, helping to ensure smooth progress, shorten construction timelines, and reduce costs.
3. Owner-led Mode
With the ongoing advancement of BIM technology, the owner-led mode has emerged as a comprehensive approach. This mode establishes a collaborative platform for all project stakeholders, enabling BIM to support project management throughout the entire lifecycle, while enhancing the owner’s control through rich data resources.
During the construction drawing and design phase, owners use BIM models to engage with design teams, gaining clear insights into design plans and progress. BIM also allows for calculating project quantity variations in different scenarios and predicting cost and schedule changes, enabling owners to select the most cost-effective solutions.
During construction, BIM models facilitate owners’ understanding of site conditions and progress control, helping them manage payment schedules reasonably. Upon project completion, the BIM model can be handed over to the operations team to serve as a foundation for space and equipment management.
The above outlines the main application modes of BIM technology. We hope this overview provides useful insights for everyone interested in BIM’s potential.
