Due to limitations in space, structural form, and the cross-sectional dimensions of components, designing the layout of pipelines and ancillary equipment requires meticulous verification of the dimensions and spatial relationships of columns, beams, slabs, and related pipelines. Drawing on current domestic experiences, the benefits of BIM-based structural design and collaboration can be summarized as follows:
1. Visualized 3D Design
Structural 3D models, as a key part of BIM integrated models, allow intuitive 3D visualization and access to detailed component information. This helps professionals from other disciplines better understand structural drawings. Traditionally, during drawing reviews, various specialists communicated using their own separate drawings. In contrast, collaboration through a comprehensive BIM model significantly improves communication efficiency.
2. Networked Collaborative Design
There are typically two approaches to 3D collaborative design:
- Workspace Feature: All project members work within the same model, using a working set that allows simultaneous data input. Each professional has read/write access only to their own discipline’s content, while having read-only access to other disciplines’ areas.
- Linking Function: Each discipline develops its own independent model but can link models from other disciplines for reference at any time. This method is particularly suitable for setups with lower computer specifications.
Both approaches require designers to promptly update their respective modifications. By regularly opening and checking the model, team members can quickly identify changes and communicate effectively.
These methods transform linear, sequential design processes into interactive, networked workflows. Professionals can work concurrently on a shared model or reference linked models within their own discipline’s environment. This facilitates optimization of process equipment and pipeline coordination, improves structural and architectural integration, and helps maintain design quality across multiple teams and tight schedules.
3. Addressing Errors, Omissions, and Clashes
The structural BIM model provides precise and realistic data on beams, columns, wall panels, equipment foundations, and supports for all disciplines. Once the layout of process equipment and pipeline routes is finalized, engineers can use Revit’s built-in Collision Check tool—or specialized software like Navisworks—for real-time clash detection and model adjustments.
This enables resolution of:
- Hard clashes between structural components, equipment, and pipelines across structural and process disciplines;
- Conflicts between structural elements and building features such as doors, windows, and steel stairs;
- Soft clashes involving plumbing and electrical lines;
- Oversights such as missing complex factory staircase platforms.
