To effectively control engineering costs, measures must be implemented across various domains, including organization, technology, economics, contracts, and information management. A unified information management system plays a crucial role in controlling these costs. According to the concept of BIM (Building Information Modeling), building components are digital objects that represent real-world building elements. This distinction highlights a fundamental difference between 3D models used for rendering and those used for presentation purposes. Let’s explore the feasibility of using BIM to manage engineering investments.
Traditional models contain only geometric data, whereas architectural information models include extensive engineering data alongside geometric details. Beyond dimensions such as length, width, and height, BIM incorporates non-geometric information like wall type, material composition, manufacturer details, procurement data, and pricing. This parametric modeling technique allows BIM to perform 3D modeling based on data associations. The dynamic attributes of BIM-based component-oriented 3D models provide a shared data foundation for generating quantity takeoffs, schedules, project costs, and other professional analyses.
Currently, BIM has advanced from simple 3D models to 4D construction simulations, integrating time or scheduling elements. This allows project teams to better anticipate the construction timeline. How is the construction schedule linked to the 3D BIM model? The project timeline is represented through the construction process of 3D components organized according to the schedule plan. This integration defines the concept of 4D (3D + time) construction simulation. Tasks generated this way can be automatically linked with BIM software, so adjusting the schedule will automatically update the 4D simulation. This association enables further management integration, forming a comprehensive 3D + Progress + Cost model.
The benefits of multidimensional models become clear when comparing how different construction companies use their own computer systems and related software. Traditional software generates various types of project information, but the flow of this information is often slow and fragmented. Some enterprises isolate parts of their information technology, leading to poor information sharing, communication, and collaboration. Multidimensional models visualize each construction task as a virtual process of assembling building components, significantly enhancing information exchange throughout the project.
Moreover, multidimensional models support different aspects of progress and site management during construction. They offer visualization, monitoring, recording, progress reporting, and plan adjustment and forecasting capabilities. For site management, they provide visualization of construction planning, support for general layout management, environmental protection, and fire safety functions. Additionally, these models aid material procurement management by assisting in preparing procurement plans, managing materials on-site, and enabling visual warehouse management.
By applying multidimensional models, construction projects can achieve extensive information sharing throughout the entire process. This improves the value of information utilization and raises the level of construction technology. Visualization reduces the workload for schedule planners by simplifying drawing reviews, shortens technical preparation time during early construction stages, and enhances the efficiency and accuracy of project preparation. It also helps construction teams better understand design intent and plan requirements, minimizing errors caused by miscommunication, improving construction progress and quality, and ensuring prompt execution of project decisions.
In summary, the feasibility of using BIM to control engineering investment is clear. We encourage everyone to share their experiences and insights so we can collectively adapt BIM more effectively to the construction industry in China.
