One of the key advantages of BIM is its ability to facilitate collaborative work. Different disciplines can design simultaneously within a shared model, enabling real-time collaboration. This approach contrasts with traditional, two-dimensional, point-to-point methods and significantly improves efficiency. For design teams, collaboration primarily occurs during the design phase and extends to all parties involved throughout the entire project construction process. The main goal of collaborative design is to enhance cooperation both within and between disciplines during the design stage.
BIM collaboration typically takes two forms: local area network (LAN) and wide area network (WAN) collaboration. These methods complement each other to overcome the limitations of isolated professional workflows and fixed geographic locations. A comprehensive BIM collaboration platform generally comprises the following modules:
1) BIM Model Management Application Module
The BIM model management module forms the backbone of the BIM collaborative management platform. It integrates all project engineering information into a unified model. Through lightweight BIM modeling, every component is embedded with detailed information, encompassing design, production, construction, and other relevant data. Unlike traditional decentralized information management, BIM models enable reverse tracking of documents related to building components, such as design drawings, change orders, construction plans, and processing details.
2) Personnel Management Module
This module includes all project participants, such as owners, supervisors, designers, procurement teams, and construction personnel. Users are organized by hierarchy and function and managed within a single unified project platform. The design phase is considered an integral part of the entire project lifecycle.
3) Process Management Module
The process management module covers the entire project workflow, including document delivery, project performance tracking, change and version control, and model transmission, tracking, and feedback. It supports BIM model sharing, review, navigation, annotation, mobile access, and comparison of drawings and model versions. Additionally, it integrates with office software and manages engineering instructions, design modifications, and construction schedules. This allows all project participants to access and manage pending tasks efficiently, ensuring smooth project execution.
4) Achievement Management Module
This module focuses on managing engineering process documents and milestone deliverables. Process documents are categorized by units and departments and include investment applications, design materials, construction documentation, correspondence, meeting minutes, and other project-related records. Milestone deliverables represent significant project stages, such as design outcomes, approval documents, completion certificates, and construction schedules. These documents are linked with the BIM model and integrated into the lightweight BIM model components.
5) Issue Tracking Module
Issue tracking is a significant feature of BIM collaborative platforms. Problems encountered during the project lifecycle are documented within the model and supported by the platform. All stakeholders can collectively identify, discuss, and resolve issues related to specific project phases online, promoting transparency and effective communication.
