The Phnom Penh-Bavet Expressway is the second expressway in Cambodia, stretching 138 kilometers and passing through three provinces. China Road and Bridge Corporation (CRBC) was tasked with constructing the expressway that would shorten travel times from two hours to 20 minutes. However, the project was located in a floodplain, with water reaching a maximum of six meters during the rainy season. The team also needed to work around Buddhist temples and culture relics. Therefore, the team chose to implement digital delivery workflows. 

CRBC established an open connected data environment using the iTwin Platform, ensuring that the team could always access the most up-to-date information at anytime and any location. MicroStation, OpenRoads, and OpenBridge helped develop models that could be shared with stakeholders. By using Bentley applications, everyone on the project worked together in a unified environment, shortening the design cycle by 20%. The terrain and geological models optimized vertical alignment, reducing earthwork volume by 2 million cubic meters and the equivalent of 2.75 million tons of carbon emissions by eliminating truck travel.
