Many design and construction firms are adopting BIM technology due to three key advantages:
1. Single Data Reuse: In traditional construction workflows, multiple project participants often enter the same project information into different software programs, such as structural analysis, regulatory compliance, material statistics, and cost estimation tools. Each of these programs operates independently, which can lead to inconsistencies in data across platforms. When information is transferred between software, it risks being altered or corrupted, causing errors. Even when compatible software is used, discrepancies may arise if different versions of project data are involved.
For example, the supervisory company must update and maintain the design documents provided by the architect. As the design evolves, all parties need to confirm they are working with the latest versions. Typically, construction teams and material suppliers receive design information in paper form and manually input it into their systems. However, as design changes occur, the project information also updates, requiring timely communication to all stakeholders. Delays or input mistakes can lead to outdated information being used, wasting time and effort.
BIM addresses these challenges by integrating project data into a unified model, greatly reducing issues related to data conversion and version conflicts.
2. Improved Design Efficiency: While BIM’s greatest benefits come from collaboration among project participants, it can also enhance traditional design processes. When design changes occur rapidly, BIM software reduces the effort needed to update 2D drawings.
For instance, in Autodesk’s Revit Architecture software, sections and elevations update automatically as the design graphics change. Similarly, Tekla Structures adjusts designs and related properties of local nodes when dimensions or geometry are modified. A BIM model rich in data can directly generate conceptual drawings, construction documents, and as-built drawings, streamlining the entire design workflow.
3. Consistent Design Platform: BIM modeling ensures all project participants work from a shared data model on a common platform. Currently, not all parties begin with the same model. When compatible software is used, data can be seamlessly shared between stakeholders.
For example, if a structural engineer modifies column dimensions, the BIM model updates immediately. Other professionals using compatible tools can then access the latest information directly. Importing all parties’ models into 3D visualization software like NavisWorks helps quickly identify design inconsistencies, ensuring coordination and accuracy throughout the project.
