$1 Billion Project In Mountainous Sichuan

Despite being only 37 km long, the 4-lane Panzhihua-Yanyuan highway project in China’s Sichuan province presents daunting engineering challenges with numerous tunnels and bridges through and over mountainous terrain, a large bridge over the Jinsha river, and a complex interchange with another major highway. Sichuan Transport Surveying & Design Institute (SCODI), the prime engineering contractor, used Autodesk model-based workflows to design all the highway elements including roadways, tunnels, bridges, interchanges, and more.

Meeting the Challenges

A highway project running through complex topography with a high tunnel ratio requires exemplary planning and design to reduce costly design changes while optimizing routes and keeping stakeholders informed and collaborating.

To achieve all these goals, SCODI used a variety of Autodesk® software products on this project, including Autodesk® InfraWorks® 360, Autodesk® AutoCAD® Civil 3D®, Autodesk® Revit®, Autodesk® AutoCAD® Raster Design, Autodesk® Subassembly Composer, AutoCAD® Map 3D, and Autodesk® Navisworks® Manage software.

The BIM Based Workflow

By combining aerial images with topographic data, SCODI created a virtual 3D model of the project area that it used to lay out proposed road alignments and add preliminary design details such as bridges, tunnels, and highway interchanges that were not just sketches but actual models with data that could be used in detailed design. This ability to design in the context of the surrounding topography gave SCODI engineers a more intuitive understanding of the engineering challenges and helped them optimize the highway design.

As a result, at the start of construction, officials are confident that the best highway would be built at the lowest possible cost and with the highest sustainability and lowest environmental impact.

“Using BIM in the design process is invaluable. BIM enables us to make critical decisions using data that can be easily visualized, so the team can find alternatives more effectively with a clear overview of the sequence.” - Timothy Suen, Arup fellow and director of railway in East Asia
“The success of BIM and model-based design for project coordination encouraged other disciplines such as rail systems, information control technology, and utilities to engage and work in a 3D model-based design environment. This in turn, has increased overall project coordination and quality.” - Ibrahim Atta-Apauk, Associate Director
“Before InfraWorks 360, there wasn’t any feasible method of bringing together and visualizing existing condition information for large infrastructure projects. It has been a ‘eureka’ experience.” — Frode Geir Bjoervik, Project Director
“During preliminary design, we usually need to develop and analyze several design alternatives with different options for the alignment, the profile, the road cross section, and so on. InfraWorks 360 and Roadway Design for InfraWorks 360 software lets us do this very quickly and easily, and then manages all of those alternatives for us.” — Daniel Iliyn, Civil Engineer, Roads & Highways
“The work we are performing with BIM for the South Terminal Redevelopment Program is not only creating a centralized system for managing the Hotel and Transit Center throughout its operational life, but is also providing Denver International Airport with a framework to deploy BIM facility-wide. ” - Julie Weinburg, Denver International Airport
“BIM offers us the opportunity to develop a huge program of improvements to Gatwick Airport without creating a massive disruption to our operation, and allows us to integrate all our projects together to see where all of our interfaces are and still deliver world class facilities for our customers” - Rod Hulse, Head of Development Engineering, Gatwick Airport Limited
“Being able to view and interact with the model on mobile devices has the potential to transform the way people communicate on projects. You can access so much information right in the field with BIM 360 Glue. As construction progresses, we expect more team members to take advantage of mobile access to information.” - Jaap de Boer, BIM Manager, iNFRANEA
“In a single InfraWorks model, we developed 17 possible road alternatives and eight different designs for the new bridge across the river. Despite the large amount of data, we could navigate smoothly through the model during our design efforts and during presentations to our client.” - Philip Hon, Road Designer/BIM Coordinator
“People sometimes equate BIM with 3D visualization, and it’s more than that. You generate a body of knowledge in BIM that can be used from conception to decommissioning.” - Neil Evans, Director of Strategy and New Business – SMEC
