River Management Effect Diagram
BIM (Building Information Modeling) involves creating a digital representation of a construction project by integrating various relevant data. This digital simulation provides an accurate model reflecting the real-world information of the building. Currently, BIM is widely implemented in real estate development, complex steel structure components, and curtain wall decoration projects. The BIM models possess five key characteristics: visualization, coordination, simulation, optimization, and drawing capabilities. This article explores the application of BIM in river management, particularly in relation to the river management projects undertaken by our organization.
River management encompasses several critical aspects: sewage treatment, river dredging, slope stabilization and protection, construction of hydrophilic platforms, paving of embankment roads, and subsequent landscape design and construction. These projects aim to transform the living environment and ensure safety during flood seasons. The primary objectives are to beautify the environment, improve living conditions, and guarantee safe drainage during floods. Consequently, the overall effectiveness of river management and the condition of the discharge sections are especially important.
During the early stages of river construction, using Revit to build a 3D information model provides an accurate visualization of the entire project. By importing terrain coordinate points, a site model can be established, allowing the 3D river model to be positioned within the site context. This clearly illustrates the spatial relationships between the site and the design structure, verifying that the design elevation and dimensions of the river sections correspond with the actual site conditions.
In addition, project management software like Microsoft Project can be used to develop a detailed project schedule, which is then imported into Navisworks’ Timeline feature. This converts the original 3D model into a 4D model by integrating time-based data, enabling comprehensive control over the construction process at various time nodes. This approach allows stakeholders to monitor project progress at any given time and resolve scheduling conflicts effectively.
Navisworks also includes a Clash Detective tool, which checks for conflicts, such as overlapping reinforcement placements within the structure. Early detection of these clashes helps identify potential construction challenges in advance, allowing for design modifications and preventive measures to ensure smooth construction. This capability is instrumental in reducing the overall construction timeline.

BIM proves equally valuable during on-site construction. Revit models clearly display detailed structural elements, precise dimensions, and the location of each sub-project, including exact coordinates and elevation points. This level of detail ensures construction teams can accurately align on-site work with the design specifications.
Once all individual Revit models are completed, they can be integrated into a comprehensive project model. Using Navisworks, animated sequences can demonstrate the entire construction process and the sequencing of various sub-projects. These animations, combined with clear textual technical instructions, enable effective communication of complex construction steps. This approach ensures that even workers with minimal formal education can fully understand the project through visual demonstrations.
BIM also enhances material management. By importing the project model into Navisworks and utilizing the Quantification tool, it becomes possible to estimate and calculate required materials accurately. In our project, this approach has resulted in approximately 5% material savings, significantly reducing costs and increasing overall project efficiency.
Though BIM is a relatively new technology in China, it holds great promise for guiding construction projects nationwide. In the future, BIM is expected to become a standard in construction practices and may even replace traditional CAD drawings as the primary construction documentation. Thanks to its five core features—visualization, coordination, simulation, optimization, and drawing capabilities—BIM plays a vital role throughout the project lifecycle: from early design, through mid-term construction management, to final project completion and review. Each application delivers notable cost savings, making BIM an essential tool for engineering design, construction, and project management that deserves broader adoption and deeper exchange.
