In the heart of innovation, nestled within the esteemed halls of the Technical University of Munich, stands TUM Boring—Innovation in Tunneling e.V.—a beacon of progress. Comprising 50 students, this initiative embodies a collective dream of crafting the future. Their ambition? Challenging the conventional paradigms of today's mobility infrastructure through a reduction in tunnelling cost. Embracing this challenge, the student team from Munich built the world's fastest tunnel-boring machine, earning them first place twice in Elon Musk's prestigious Not-a-Boring Competition. Hosted by The Boring Company, this event challenged teams globally to demonstrate their prowess in drilling a tunnel both swiftly and precisely—30 meters in length and 50 centimeters in width. Journey with us as we recount a tale of audacity and resilience—from the project's humble beginnings in July 2020 to winning the competition twice. Uncover how a team of students spent 40 days tirelessly working on their machine on a ranch in Texas, encountering and solving unconventional challenges every day, to prepare for the competition. Within this narrative, uncover the spirit of 50 passionate students who, disobeyed conventions forged ahead, won competitions, and redefined what is possible in the realm of tunnel boring.

On rail infrastructure projects, consultants provide tunnel ring models for entire alignment, created using a two-point adaptive family based on the track center point via Dynamo. But these models lack detailed tunnel features—segmentation and dimple holes. Coordination with stakeholders requires complete tunnel models with segmentation and dimple holes. We must develop this detailed model to accurately place services brackets along the tunnel. The ring comprises eight segments, including a key segment with a varying location. A family of these segments, with a rotation parameter set by the tunnel's center point, is essential. Our process involves deriving the tunnel's center from track center points using geometric translations. Dynamo makes placement points for adaptive components. The angle of rotation is recorded on the site for the key segment in XYZ, and we develop construction model using that data. This construction model aids subcontractor in accurate service modeling.

The Studio Wind Tunnel Project will bring simulation insight and guidance to the automotive design community. With seamless integration into existing design pipelines, fully automated virtual wind-tunnel analysis will enable studios to assess performance criteria, visualize airflow, and make informed design decisions at any stage of development. Designed to provide reliable and consistent insight, the Studio Wind Tunnel Project solves traditional challenges associated with vehicle aerodynamic simulation.

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.

Large-scale underground infrastructure projects push BIM workflows to their limits, especially when dealing with tens of kilometers of tunnels and tens of thousands of repetitive elements. This session will present a real-world case study from a major Australian hydropower project where BIM was implemented across both design and construction phases. We'll focus on the processes developed to efficiently model more than 40 kilometers of tunnels and more than 35,000 rock bolts, ensuring consistency, performance, and constructability. By combining Revit, Civil 3D, Dynamo, and Autodesk Forma (formerly Autodesk Construction Cloud), we established automated workflows for geometry generation, data structuring, and model coordination.

Technology is growing rapidly and Revit software is no exception. It started with limitations of a few kilometers, and with time went over to tenths of kilometers as a model-size limitation in Revit. Despite of this, rumor still has it that Revit can't be used for large spanning projects. Engineers wouldn't be engineers if they took "no" for an answer, and we didn't. Instead, we chose the most extreme project-the world's deepest and longest subsea road tunnel "Rogfast"-and made it happen. Take Revit and marry it with Dynamo software and you have the ultimate solution for any challenge. Join the session and see it for yourself. We will share workflows developed and lessons learned.

This session presents a real-world tunnel infrastructure project that leveraged parametric design to reduce construction risk and improve coordination. A parametric adaptive ring family, developed in collaboration with Autodesk, served as the base for a modular tunnel model in Revit. Using Dynamo, both primary and secondary structures were generated, and system layouts were added for space proofing. The model was then integrated into Autodesk Forma to support cross-disciplinary collaboration between structure, MEP, and design teams. This connected workflow improved communication, reduced errors, and supported earlier decision-making. Attendees will discover a scalable strategy for managing complexity in linear infrastructure projects and see how parametric design helps create robust, coordinated models ready for execution.

This presentation will go over the initial planning and execution stages of a Building Information Modeling (BIM)-driven project to create a new 2-lane tunnel under Thimble Shoal Channel in Virginia. When complete, the new tunnel will carry 2 lanes of traffic southbound and the existing tunnel will carry 2 lanes of traffic northbound. The project design is quite a challenge, as it's meant to connect to an existing highway and tunnel system in such a way as not to disturb the flow of traffic during construction. Using AutoCAD Civil 3D software, Revit software, Navisworks software, and additional Autodesk software, we were able maximize our use of the model data, not just for construction documents, but also for analysis. Coordination of not just the design data, but also the various teams and interests on the project, were integral to making it successful.

Tunnel rehabilitation projects lack a single, bulletproof workflow for comparing complex point cloud data with design corridors. Instead of chasing a one-size-fits-all solution, successful projects require selecting the right toolset for the specific job. This session explores the current state of the art in working with tunnel point cloud meshes using ReCap, Civil 3D, and Dynamo. Rather than presenting a single rigid path, we will dissect multiple methodologies, analyzing the practical pros and cons of each. You'll leave with a clear understanding of what is realistically possible right now, how to automate section creation, and how to select the optimal workflow to balance accuracy against automation scale.

Advanced building information modeling (BIM) processes require us to consider modeling with different lenses: personas interacting on a shared model extracting different BIM uses throughout the different project lifecycle stages. We'll look at the specific case of "tunnel ring segment” modeling and all the phases that have been conducted to a Revit model that is open, universal, and fully parametric so it can be used from bidding to execution and from planners to fabricators. The class will show how Bouygues Travaux Publics went from collecting users' needs to formalizing a specification and developing a Revit family and all its applications in Revit, InfraWorks, Navisworks, and Autodesk Forma. We'll focus on the benefits realized with the application in a project now in the construction phase.

Building the world's fastest and most automated tunnel-boring machine can solve the key bottleneck for the transition to sustainable energy: laying thousands of miles of power cables. That's why 60 highly motivated students from Munich's major universities have teamed up to demonstrate that this is actually possible—by winning Elon Musk's Not-a-Boring Competition. Learn how we work in interdisciplinary subteams on a 22-ton machine with more than 10,000 components using Autodesk Fusion software—from end to end. Find out how we go through the entire product development cycle from design to manufacturing, and how we optimize all the different subsystems to achieve our goal.

It is complex to model structures such as viaducts and tunnels that are controlled by an alignment and profile. Put that in an environment where the alignment changes often, and the structural engineer, using a tool like Revit software, finds it hard to accommodate that change. AutoCAD Civil 3D software is great for designing the alignment and profile—with complex curve elements and subassemblies for the mass modeling of complex structures—but we need Revit software for the detailed concrete modeling. Solutions to the challenge involving export/import of data between software have helped, but they present their own new challenges. This is where writing Dynamo scripts comes into play, providing integration and coordination between AutoCAD Civil 3D software and Revit software to give an interactive and dynamic modeling environment that can integrate structures like stairs and the MEP (mechanical, electrical, and plumbing)-required equipment. This class uses custom AutoCAD Civil 3D software subassemblies, Dynamo scripts, and Revit families. This session features AutoCAD Civil 3D, Dynamo Studio, and Revit.

We made a digital twin (DT) of the tunnels that we manage on behalf of the province of North Holland. We're responsible for operating, controlling, and monitoring those tunnels. The data of the tunnels in the DT make the management and maintenance process much easier. Through its application, the DT is a central database in which we as tunnel administrator—along with the subcontractors and our client—can work directly. Accordingly, we all have up-to-date information about the status of the asset. As an administrator, we know the status of reliability, availability, and safety at all times. The contractor can immediately assess the severity and nature of defects and immediately has insight into the required material for carrying out the maintenance. Based on current information, the owner can make strategic decisions. An extensive effort was necessary regarding the original working method. With the DT, the process steps were reduced by almost 50%.
