(1) BIM technology plays a crucial role in supporting cost management by providing comprehensive information throughout a building’s entire lifecycle. While BIM covers almost every phase—from design through construction and operation, excluding demolition—it is gradually becoming fully integrated with green building practices. This integration enables multiple disciplines to collaborate seamlessly on a unified data platform within BIM models, ensuring data accuracy at each stage of the lifecycle.
By applying BIM technology from the design phase through construction, it becomes possible to directly calculate quantities of materials, simulate construction processes, and optimize construction planning. During the operational phase, BIM enhances the comprehensive understanding of the building among management teams, ensuring seamless information transfer and supporting effective cost management. Furthermore, since BIM encompasses nearly all relevant building information, it provides a robust platform for professionals to perform performance simulations, spatial demonstrations, and green building analyses.
(2) BIM technology also facilitates performance simulation and analysis critical to cost management. Without BIM-based simulation during construction, practical project development can lack cohesion. BIM’s core value lies in its ability to visually represent architectural designs that evolve dynamically with real-time construction changes. This dynamic simulation enables various disciplines to quickly explore and analyze different scenarios, offering an accurate reflection of the building’s actual status. Integrating dynamic “design analysis simulation” ensures that stakeholders receive reliable data to make informed decisions.
Broadly speaking, BIM provides a reliable foundation for managing green building construction at every stage, enabling detailed quantitative analyses. The integration of computer-aided simulation with architectural design creates an intuitive, cyclical process of design and feedback, optimizing project cost management.
(3) BIM outputs are interconnected and consistent across stages. BIM’s workflow is characterized by two core attributes: collaborative methods and collaborative participants. Their combined effect determines the efficiency and scientific rigor of construction projects. Traditional projects primarily focus on visual representations such as 2D drawings, while BIM models are gaining widespread acceptance as a more comprehensive approach.
However, construction collaboration spans multiple enterprises, regions, and languages, presenting significant challenges. To enable effective collaboration, it is essential to establish an internet-based management platform that supports diverse participants. This platform must provide accurate and complete information—covering geometric, physical, and functional data integrated within the BIM model—so stakeholders can make timely, informed judgments and decisions. This collaborative approach ensures high-quality outcomes and cost efficiency throughout the project lifecycle. Today, any design process conducted on a network platform that facilitates communication and organizational management is considered collaborative design. At its core, collaboration revolves around data creation, management, and sharing, which forms the foundation of digital informatization.
