The GBP 1 billion Core Valley Lines (CVL) Transformation project will add new track loops, increase line speed, update signaling systems and stations, and introduce new hybrid battery-electric trains to the Cardiff region of South Wales. Amey was tasked with providing an initial design of the project, constructing the overhead line assets and a new train depot, and ensuring the safe operation and maintenance of the entire line. The team realized that, to securely and efficiently manage data across four main contractors and numerous subcontractors, they needed a connected data environment. While Amey first used a simple web-based connected data environment, they quickly realized that it could not meet their needs. They migrated the system to ProjectWise for a whole-service offering, allowing over 1,500 users across 40 organizations to share project data—including designs, reports, and surveys. The team also developed over 30 different, ISO 19650-compliant, automated workflows for improved collaboration and management of assets. When complete, the project will improve line accessibility, providing four trains per hour on most of the network, and reduce carbon emissions throughout the network.
