The Autopista Urbana Sur (Urban Highway South) is an 11.3 km long elevated highway in the southern part of Mexico City. When fully complete, the highway will relieve chronic traffic problems in that part of the city, cutting travel times in half and providing future capacity to cope with the city’s increasing population. Large sections of the road are already complete and open to traffic. The new road, which is being built above Mexico City’s busiest expressway, features two lanes in each direction with some stretches of six lanes and connects to the city’s existing elevated peripheral highway.
Given the dense urban environment in this area, the road was built using prefabricated concrete sections made offsite, then transported to the site and installed at night to minimize traffic disruptions. The components were hoisted into place with large cranes, adding to the congestion of the construction site. ICA Ingenieria provided engineering, procurement, and construction services, including BIM services delivered through its ICA BIM division.
ICA used a wide range of Autodesk solutions on this project, including Autodesk AutoCAD software, Autodesk Revit software available in the Autodesk Building Design Suite, Autodesk AutoCAD Civil 3D software, Autodesk Recap™ software, Autodesk Navisworks Manage software, and Autodesk 3ds Max Design software. Model-based software and workflows supported better coordination and communication between all the project stakeholders. This led to improved design delivery through discipline integration, and enabled the creation of very precise construction logistics that were required for the transportation and erection of the prefabricated components.
In areas were the road passes through very dense city infrastructure, ICA performed laser scanning and imported that data into 3D models to help refine planning and construction. The team combined the point cloud data and the project design models for improved construction simulation, coordination, and interference detection and resolution. Linking the project model to construction data helped enable the early detection and correction of schedule and costs issues. In addition, the models helped ICA communicate the project’s complex scheduling and logistics to its government client and other project stakeholders for improved project decision making and public outreach.
BIM enables ICA to use innovative techniques like prefabrication, as well as advanced simulation and cross-discipline collaboration in a complex civil construction project.
