BIM technology offers a comprehensive, efficient, and visual management method for overseeing various stages and components of engineering projects through systematic management. Building Information Modeling presents data through detailed models, creating an intuitive interactive interface that visualizes multiple aspects of construction projects. These aspects include project initiation, drawing design, 3D rendering, internal structural design, collision detection, virtual modeling, data analysis, and progress monitoring, making it easier for users to understand and control the process. Given the complexity of a construction project’s entire lifecycle, applying BIM at each stage ensures more effective information management throughout.
1. Planning and Design Phase: This initial stage involves analyzing the necessity of the project based on the investment and requirements of the construction party. For individual projects, this is called planning; for group projects, it is also referred to as planning. The focus is on proposing a reasonable scale and defining the conditions for both planning and design. Key activities include site selection, conceptual model development, and evaluation of construction conditions.
2. Scheme Design Phase: This critical phase requires selecting a comprehensive scheme that fits the project type, size, and budget. It includes outlining the work process, key participants, and data flow relationships. The scheme design involves site analysis, comparing and selecting design options, and performance evaluation to finalize the project scheme.
3. Preliminary Design Phase: As the initial design stage, it covers a broad range of content such as feasibility studies—technical, cost-related, and economic policy assessments—and preliminary estimates of project benefits and expenses. It also involves creating an overall plan addressing potential risks, providing thorough quantitative analysis to support decision-making and ensure the project’s smooth progress.
4. Detailed Design Phase: Building upon the overall scheme and planning, this phase focuses on detailed project designs. It includes construction drawings, pipeline and air duct layouts, and installation plans for various components. Besides producing complete construction documents, this phase supplies comprehensive guidance for on-site work, including material lists, quantities, and model specifications.
5. Construction Phase: This phase spans from the signing of the construction contract to project completion. During this time, multiple sub-projects often overlap, with BIM integrated throughout. Key applications include on-site data collection, drawing reviews, deepening design adjustments, construction simulation, prefabrication processes, site layout, quality and safety management, and equipment/material tracking. BIM supports conflict detection among pipelines and equipment, construction plan analysis, and overall process control.
6. Delivery and Operation Phase: After completion, the project is handed over to the client following thorough quality inspections and functional acceptance tests. Important materials like final drawings and maintenance information are carefully transferred during this phase. Post-delivery, BIM continues to support the project’s operational management and maintenance.
