Mott MacDonald Systra (MSD JV) was awarded the design-build contract for phase 1 northern sector civil works of the High Speed 2 railway network (HS2). However, they had to manage over 1,000 people working from 30 locations across over 18 disciplines, as well as terabytes of data. The project had transformed in size since its onset, requiring more standardized processes and new technology for effective data management, change control, and transparent communication.Already using ProjectWise, they integrated the Bentley iTwin platform, accelerating model access by 95% to save an expected GBP 200,000 annually, as well as reducing data extraction time from two weeks to within hours. They streamlined new deliverable creation with automatic metadata retrieval, reducing manual entry by 75%. Integrating advanced work packaging drastically reduced reporting times and streamlined information sharing, accelerating the project schedule.
