BIM Q&A | BIM Application in Aviation
Application 1: Design Proofreading
One common challenge in China’s construction industry is that design drawings often cannot be directly used for construction. This issue also applies during the BIM phase—not because BIM is ineffective, but because the construction and design teams focus on different aspects. Therefore, the construction team must further refine the design team’s models or drawings. BIM software plays a key role in this process by verifying and detecting design errors, generating clash detection reports, and providing feedback to the design team with suggested modifications. The model is then updated and retested until all design issues are resolved. Additionally, by using models and virtual demonstrations to simulate critical points in bridge construction, collision checks are performed, reports are automatically generated, and potential design errors are identified and corrected in advance. This proactive approach helps avoid cost overruns and economic losses caused by project delays.
Application 2: Rapid Workload Generation
Calculating the bill of quantities for traditional bridge engineering is a complex and time-consuming process, involving many variables and frequent revisions by estimators. With BIM, relevant data such as part numbers, quantities, materials, weights, and specifications can be imported directly into the model. Automated functions then generate the bill of quantities, significantly reducing repetitive manual work. Moreover, BIM models feature real-time data linkage, so any changes in information automatically update the quantities, ensuring consistency with the actual project. This improves both accuracy and efficiency.
Application 3: Process Simulation
Construction teams can leverage BIM’s simulation capabilities to link bridge engineering models with construction methods and related data, enabling them to simulate construction processes. This allows personnel to identify challenges and critical points during construction, make detailed annotations, and develop practical, feasible construction plans. The entire construction process can be simulated to guide on-site operations. Through interactive walkthroughs and construction animations, vivid and realistic guidance is provided, ensuring smooth progress and quality outcomes.
Application 4: Progress Simulation and Cost Control
During construction, the original BIM model can be enhanced by adding 4D (time) and 5D (cost) dimensions. This enables simulation of the project schedule on a daily, weekly, or monthly basis, allowing real-time adjustments based on site conditions. Different construction plans can be analyzed to determine the most efficient approach. By linking cost information such as materials and labor, BIM simulates material usage, workforce flow, and resource allocation throughout the project. This supports effective cost management, refines project control, and fundamentally eliminates unnecessary expenses.
