BIM has revolutionized the way design schemes are presented. By replacing traditional 2D designs with 3D models, BIM enables a clearer visualization of the design, making it easier for reviewers, owners, and users to evaluate the scheme. This enhanced visualization also fosters discussions on the feasibility of the design, ways to reduce costs, and shorten construction timelines. After thorough review, feasible solutions are proposed to refine the design.
Once the design scheme is finalized, the design process can be further developed, with BIM continuing to play a crucial role throughout architectural design. BIM-based design software uses 3D building components—such as walls, doors, windows, and stairs—as the fundamental graphic elements for building the BIM model. All relevant data is integrated within this model, making the BIM model itself the primary deliverable of the design phase.
The key roles of BIM during the design phase include:
1. Scheme Presentation and Comparison: BIM models intuitively convey design concepts, enabling quick capture of the owner’s feedback and efficient implementation of modifications. By balancing owner requirements with construction and cost considerations, the best design scheme is determined.
2. Collaborative Management: Multiple management personnel are involved in the design process, creating a unique real-time collaborative platform. Participants can access the design model remotely via the internet, collaborate in a virtual environment, and provide or comment on feedback.
3. Timely Information Exchange: BIM facilitates prompt communication among owners, designers, and construction teams, allowing for rapid response to ideas and efficient revisions.
The BIM application process during the design phase can be broken down as follows:
1. To enable real-time collaboration among the three main stakeholders—owner, design institute, and construction team—AUTODESK software is selected to establish the BIM model. Simultaneously, BIM application rules and modeling standards are developed in coordination with the design team for various specialties. Additional software like Tekla, SketchUp, and 3DMAX are used to create auxiliary models for management purposes. A BIM data integration platform ensures seamless, bidirectional data exchange and sharing between different software. The BIM platform and mobile clients enable data access and sharing among all participants. Upon project completion by BIM designers, all parties use the platform for asynchronous collaboration, making changes, revisions, or downloading and analyzing the model. This ensures timely information flow and efficient updates based on owner and contractor input.
Summary: EPC projects benefit from integrating design and construction models early on, and incorporating construction information during the design phase greatly supports model continuity.
2. During design, the BIM platform facilitates real-time communication and interaction with the construction team, leveraging EPC project advantages to minimize losses caused by engineering changes. Multiple management personnel collaborate on a unique real-time platform, accessing the design model remotely to work together in a virtual environment and provide feedback.
Summary: Capitalizing on EPC project strengths, using the BIM platform early in design, enhancing BIM data, and embracing the integrated design and construction concept are key highlights of BIM use in EPC projects.
3. During the scheme design phase, BIM models visually convey design concepts, capture owner feedback quickly, and streamline the modification process. By balancing owner requirements with construction and cost factors, the optimal design scheme is chosen. The 3D model created at this stage also serves as an information carrier for procurement and construction phases.
