Decision-Driven Parametric Tunnel Design Using Shared Project Data

Many tunnel projects rely on static design approaches that limit the ability of stakeholders to anticipate construction risks and adapt to evolving constraints. This session will present a decision-driven parametric design approach for tunnel and cross-passage modeling using shared project data accessible to stakeholders. Based on a real tunnel project in the United Kingdom, we'll demonstrate how Dynamo-driven workflows enable rapid iteration of design scenarios and validation of geometric constraints. The session will also highlight collaboration between design and construction teams using shared linear references. We'll also share how value was assessed, including reduced design iterations, improved risk anticipation, and faster decision making.
