Nowadays, Building Information Modeling (BIM) is extensively used in both design and construction phases. Today, the editor of the BIM Building Training Network will provide an overview of common BIM applications for your reference.
BIM Model Maintenance
Maintaining a BIM model according to project construction progress involves using a BIM platform to consolidate all project information from various teams. This process eliminates information silos and organizes data alongside a 3D model, enabling seamless sharing among all stakeholders throughout the project lifecycle.
The intended purpose of BIM dictates the level of detail and accuracy within the model. Since no single BIM tool can fulfill all project requirements, the industry typically adopts a “distributed” modeling approach. This means creating BIM models that align with the current conditions and intended use of the project, which may include design models, construction models, scheduling models, cost models, manufacturing models, and operational models as needed.
This distributed approach also means that different design, construction, or operation teams often develop their own BIM models within their scope of work. These models are then integrated following unified standards. While effective, this method increases challenges related to managing modeling standards, version control, and data security. As a result, some owners hire independent BIM service providers to centrally plan, maintain, and manage BIM applications for the entire project to ensure accuracy, timeliness, and data security.
Visual Design (3Dmax, SketchUp)
The introduction of 3D visualization software such as 3Dmax and SketchUp has helped bridge the communication gap between owners, end-users, and designers who may find traditional architectural drawings difficult to interpret. However, due to the limitations of these tools in terms of design concepts and functionality, 3D visualizations—whether used for preliminary scheme refinement or phase renderings—often differ considerably from the actual design.
For designers, although these tools assist in early-stage considerations and presentations, much of the detailed design work still relies on traditional CAD platforms using plans, elevations, and sections to communicate design intent. This tool fragmentation can lead to errors, especially in complex projects with tight schedules.
BIM offers designers advanced three-dimensional visualization tools that truly reflect the final design—what you see is what you get (Figure 4). More importantly, BIM encourages designers to adopt three-dimensional thinking throughout the architectural design process. Simultaneously, it allows owners and end-users to overcome technological barriers and gain clear insights into what their investment will achieve at any time.
Quantity Surveying
During the CAD era, since CAD files lacked the information necessary for automatic quantity calculations, quantity surveying depended heavily on manual measurements from drawings or CAD files. Alternatively, specialized cost estimation software would require re-modeling based on these files to perform automated calculations. Manual methods were labor-intensive and prone to errors, while software-based approaches demanded timely updates to remain accurate. Delays often rendered the quantity data invalid.
BIM, being a rich engineering information database, provides precise quantity data essential for cost management. With BIM, computers can quickly analyze various components, dramatically reducing manual effort and minimizing errors. This ensures complete consistency between quantity data and the design scheme.
Accurate quantity data from BIM supports cost estimation early in the design process, allows owners to explore different design options within budget constraints, facilitates cost comparisons between design alternatives, and aids in quantity budgeting before construction begins, as well as final settlement after project completion.
That concludes today’s summary. We hope you continue to follow our updates.
