The construction phase of a building project is the most resource-intensive stage, involving significant personnel, materials, and machinery. It also tends to encounter the most challenges throughout the entire project lifecycle. With the advancement of Building Information Modeling (BIM), the value of BIM technology during the construction phase has become increasingly vital. Therefore, leveraging BIM technology to address various construction-phase issues is essential.
Before construction begins, the 3D visualization capabilities of BIM provide a realistic representation of the proposed building, displaying detailed information about its design. BIM models facilitate coordination between design and construction teams, ensuring a seamless transition and integration between these stages. By promoting collaboration across various disciplines, BIM enhances communication, reduces construction costs, and helps guarantee the project is completed on time and to high-quality standards. Additionally, BIM enables collision detection, identifying conflicts in building components such as structures and pipelines, allowing for timely updates and optimizations to the model. This supports a scientific and efficient organization of the construction site.
During construction, BIM’s simulation technology allows teams to model the construction plan, offering clear guidance while optimizing the allocation of resources like labor and machinery. BIM also enables the comparison of multiple construction scenarios to select the most efficient plan, minimizing waste and lowering costs. Through BIM, construction projects can be accurately quantified, compared, and precisely managed, leading to significant resource savings. Moreover, BIM ensures the integrity of building models by storing all relevant construction information, which improves the efficiency of project finalization and settlement.
In the completion phase, BIM models combined with engineering data facilitate the final project settlement. All construction data is systematically organized and summarized within a BIM information integration platform, creating an enterprise-level BIM case database. This database serves as a valuable reference for cost control in future similar projects.
In summary, the key applications of BIM during the construction phase of building projects include: ① Drawing review; ② Design development; ③ Quantity takeoff; ④ Construction organization and optimization of construction plans; ⑤ Management of design changes; ⑥ Construction simulation; ⑦ BIM information integration and establishment of a BIM database.
