During the construction phase of engineering projects, BIM heterogeneous data integration methods primarily include information integration control and 3D visualization. Information integration control involves using specific data exchange methods and standards to extract and convert BIM model data. This approach facilitates effective data mining of heterogeneous BIM data, enhances data utilization efficiency, supports construction-phase project management, and ultimately improves the overall project benefits.
On the other hand, 3D visualization integration focuses on combining various visual forms of heterogeneous BIM data. This method provides project managers with a comprehensive and intuitive understanding of project data, aiding them in making informed management decisions efficiently and centrally. For example, integrating 3D models with virtual construction simulation animations enables dynamic 3D visual simulations. These simulations help analyze and inspect spatial structures and construction planning, allowing better preparation for upcoming construction activities and promoting smooth project progress.
Information Integration Control
1. Integrated control of model information. This method centers on building components within the model, such as columns. Traditionally, different data types are viewed and shared through multiple separate model files. With model information integration control, details like type, material, and geometric dimensions are consolidated into BIM components. This enables centralized management of all project-related data linked to each component, significantly improving data utilization efficiency.
2. Integrated control of project management information. Project management information includes crucial data such as costs and schedules. Integrating 3D models with the construction schedule based on model quantification reflects both spatial and temporal attributes within the BIM model, allowing effective progress control during construction. Project managers can monitor construction status by tracking quantities completed and comparing planned versus actual progress. This visualization provides clear, intuitive insights into site progress, ensuring that the construction schedule is both reasonable and achievable.
Regarding cost management, integrated control involves designing overall construction organization and simulation plans. This includes planning personnel, materials, and machinery use, resource tracking, material coding, and linking these elements to the construction schedule to produce a material list. Compared to manual calculations, BIM-generated lists enable integrated material management, verify usage plans, and reduce errors in material picking. The BIM-based data management platform allows real-time sharing of cost data, supporting detailed and efficient project cost control during construction.
3D Visualization
The 3D visualization integration method utilizes BIM technology to create a 3D layout model of the construction site before beginning work. This model accurately represents the site dimensions and visually displays the site layout, enabling effective planning of construction zones and traffic organization to prevent site disorder.
To ensure construction quality and project goals, BIM is used to simulate key construction plans virtually, identifying potential challenges and issues in advance. These simulation results serve as reference materials for on-site personnel to understand and prepare. Additionally, complex construction processes can be animated to highlight critical stages and techniques, facilitating proactive construction management.
BIM’s visual simulation capabilities also support thorough review and optimization of design drawings. One common application is 3D clash detection, which checks for conflicts among structural components, installation pipelines, and mechanical and electrical equipment within the model. Based on these findings, design adjustments are made until no clashes remain. For example, in mechanical and electrical installations, 3D pipeline simulations ensure accurate layouts and resolve drawing errors beforehand. In building structures, BIM simulations help locate reserved openings early, preventing conflicts between masonry work and installations.
