Case Study: Arup improves tunnel impact assessment automation with Oasys XDisp

Arup automates tunnel impact assessment for 5,000+ stages with Oasys Software

Arup, a global engineering firm, faced a significant challenge in assessing the tunnel-induced impact on thousands of existing assets and utilities for a large infrastructure project. Traditional numerical methods were unable to handle the sheer scale of the six-mile tunnel project without risking software overload. The Arup geotechnical team needed an innovative solution to automate this complex settlement analysis under tight time constraints, turning to Oasys Software and its Oasys XDisp product.

The solution implemented by Oasys Software involved a unique automated workflow. Arup developed a Python script to work with Oasys XDisp, creating asset-specific models from a master file to sequentially calculate longitudinal impact. This approach allowed the team to run thousands of models and determine precise volume loss values, showing that a fixed line-wide settlement limit was not the best approach. Oasys XDisp was hailed as a game changer, enabling Arup to deliver more efficient and faster impact assessments, which was crucial for a project of this scale.
