Through the application of Computational Design (CD) on infrastructure projects, ILF Consulting Engineers breaks new ground. The approach was based on combining the CD skills with engineering and software expertise. Together, this combination was able to recognize the possibilities and streamline design processes with increased quality and time savings.

ILF tunneling experts used CD to create optimized tunnel profile designs for the creation of building information modeling (BIM) models of tunnels based on real-world tunnel projects. Using generative design solutions which allow the user to set variables and desired goals such as minimum excavation area and/or required ventilation area, an optimized tunnel cross section is produced and used in turn for the creation of the BIM models.

A further example involved the design of tunnel branches based on inputs such as typical cross section data, alignments, gradients, chainages and cross slope information. A parametric 3D model of the tunnel branch geometry and 2D sections of the tunnel profiles are produced. By reducing the time for production of design alternatives to 20 %, various alternatives can be considered and the quality of the final design can be optimized.
