The comparison of collaborative design schemes based on BIM technology is conducted with a focus on the full lifecycle cost of engineering projects. Unlike traditional models, BIM collaboration begins at the conceptual design stage, allowing various disciplines to work together early on. Considering the entire lifecycle and future operational costs, the goal is to select the optimal design scheme, rapidly modify plans, reduce repetitive work, and enhance design efficiency. The following outlines how BIM technology is applied in cost control during the decision-making phase of engineering projects:
1. Collaborative Work. Traditional two-dimensional design often causes numerous issues due to poor communication between different disciplines and the challenge of interpreting abstract drawings. Fixing these problems requires design changes, which can significantly delay construction and increase costs.
BIM technology enhances horizontal communication by integrating all disciplines into a unified platform. This allows for real-time collaboration during the design process. Each discipline can access the latest design models at any time and link them as needed. Permissions for model modifications can be controlled to prevent errors. Additionally, BIM’s collision detection feature integrates all professional information models to identify clashes early, facilitating easy review and modification. This proactive approach helps reduce costs right from the design stage.
2. Plan Optimization and Comparison. Traditionally, scheme optimization involves creating a 3D model based on completed 2D construction drawings, followed by energy consumption analysis and subsequent adjustments. Poor communication among architecture, equipment, and cost disciplines, combined with late involvement in optimization, often leads to extensive rework when issues arise, disrupting subsequent design stages.
3. Engineering Quantity Statistics. The preliminary budget during the design phase is critical for evaluating the project’s economic feasibility. Accurate quantity takeoff is fundamental for cost control. Traditionally, this involves extracting data from CAD drawings, with budget personnel calculating quantities based on their understanding of the drawings, quantity calculation rules, and professional expertise. The accuracy of these statistics depends heavily on the skill and experience of the budget team.
In summary, BIM technology plays a vital role in cost control during the decision-making phase of engineering projects by facilitating collaboration, optimizing plans, and improving quantity statistics. We hope this article provides valuable insights for everyone!
