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.

Projects of this size and complexity require farsighted management—and proactive attention to the smallest details. Everything from conduits to pipes to ducts needs to fit together during construction, and even relatively minor coordination issues could lead to delays and higher costs.
For SMEC, the solution lay in the integrated use of Autodesk® tools including AutoCAD®Civil 3D®, Autdesk® Revit®, Autodesk® Vault® Professional, and Autodesk® Navisworks® Manage to enable a coordinated design process based on intelligent modeling. Various design models come together within a federated 3D model that resolves details and identifies clashes, to stay on budget while improving the design.

Keeping a Complex Rail Project on TrackSee the Project
The Shatin to Central link, a 17 km railway line expansion for Hong Kong’s Mass Transit Railway (MTR), involves large-scale construction in one of the world’s most built-up and busiest commercial areas. The project includes 1.8 km of new twin railway tunnels, a new underground station with interchange facilities, plus ventilation buildings and shafts on Hong Kong Island
With its complexity and logistical challenges, the venture was just the sort of project that appealed to Arup, a worldwide design and engineering firm renowned for its engineering consultancy and professional services.
The Shatin to Central link involved almost every engineering element to be found in a civil project: demolition and modification of existing structures, brand new construction, consideration for tying into existing or future infrastructure, and a wide scope of legal, safety, traffic, and business impact issues.
Armed with Autodesk BIM tools, the Arup team felt well prepared to meet any design parameter presented by MTR. What soon became apparent was that the keys to project success lay in close coordination and communication among the myriad stakeholders in the governmental, engineering, and construction sectors.
