The larger and more complex an engineering project becomes, the greater the value of applying BIM models in construction.
Before starting road construction, technical briefings are often necessary. The goal is to ensure that construction personnel fully understand the technical requirements, quality standards (acceptance criteria), construction methods, and procedures for each sub-project. This detailed understanding helps organize construction in a scientific and efficient manner, preventing technical errors, quality defects, and common construction issues. Traditionally, these briefings are conducted orally or in writing, which can lead to misunderstandings, unclear instructions, and consequently, mistakes, rework, or changes. Using BIM for visual briefings offers a more intuitive and clear presentation, allowing construction teams to repeatedly review the design intent and construction details. This approach enhances the accuracy of construction plans, improves coordination, and enables proactive safety planning to ensure the project progresses smoothly.
Currently, road construction projects commonly use progress bar charts to represent scheduling plans. However, these charts cannot clearly convey the construction progress or the complex relationships involved, making it difficult to accurately track dynamic changes during the construction process. By integrating 3D BIM models with time-related data, a visual 4D model can be created that intuitively and precisely reflects the entire road construction process. This allows for better planning, accurate progress tracking in 4D, optimized resource utilization, and scientific site management. Unified control over progress, resources, and quality helps shorten construction timelines, reduce costs, and improve overall quality.
Construction organization plays a crucial role in implementing scientific management throughout the construction process. It defines the necessary preparation at each stage and coordinates the relationships among construction teams, tasks, and resources. Road engineering is a linear type of project, often involving long routes divided into multiple sections and work zones for simultaneous construction. It also includes various sub-projects such as subgrade preparation, pavement, bridges and culverts, landscaping, safety facilities, and major systems. Managing these requires coordinating the overall project timeline, scheduling for each section, process synchronization, and handling cross-operational tasks. As road construction projects grow in scale and complexity, the organization becomes increasingly challenging. BIM can simulate the feasibility of critical or complex elements, analyze and optimize construction and installation plans on a monthly, daily, or even hourly basis. It enables simulation and analysis of key construction processes, innovative techniques applied to critical parts, and site layout arrangements to enhance plan feasibility. Furthermore, BIM technology supports rehearsal of construction organization plans to improve the constructability of complex structures, such as formwork, assembly, and anchoring.
Using BIM models also facilitates digital construction management in road projects, boosting both work efficiency and construction quality. For instance, the route’s plane layout, vertical elevation control, and automated monitoring of compaction and deflection during roadbed and pavement construction can be directly integrated into the model through information exchange. This strengthens quality control on site and ensures construction meets design specifications.
