This duplicate modeling work can be avoided by automatically creating a relevant structural model from a parametric architectural model. As a result, design work is mostly carried out as two separate processes – the architectural design and geometric modeling using BIM, and, separately, the creation of the structural analysis model by the bridge engineer. Structural engineers undertake this analysis by considering the statically relevant relationships and the required accuracy of the calculations. The detailed geometry of 3D models is not suitable for structural analyses, requiring simplifications to be made. By providing functionalities such as structural analysis and strength assessment, the BIM tool Allplan Bridge addresses this issue and extends the benefits of the BIM methodology to all parties involved on the project.īenefits of an Integrated BIM Approach Efficient Structural Analysis
Thus, being able to use the BIM process as a fully integrated planning procedure – including detailed structural analyses and assessment – and allowing all parties to collaborate on a project has exceptional value. However, these disciplines often sit outside of a traditional BIM workflow and, as such, do not fully benefit from the enhanced efficiency, communication, and collaboration that BIM could provide. For example, structural analyses require experienced bridge engineers, and often additional help from experts to address unique challenges such as geotechnical and foundation issues, pre-stressing, or earthquake engineering. In bridge design and construction, apart from the geometrical design, coordination work, and construction management, many other sophisticated design tasks are required which are performed by specialists.
