Data Management System for the S1S2 Tunnels of the High -Speed 2 Link Project in
The S1/S2 contract for the new High Speed 2 (HS2) in the United Kingdom linking London to Birmingham and later Leeds and Manchester will consist of 22 km of tunnels and is estimated to cost GBP 3.3 billion. As part of the contract, an Instrumentation & Monitoring data management system to support the construction phase (Phase 2) is provisioned. This paper discusses the development of the data management system with an emphasis on linking data from multiple sources to enable more effective data analysis. The system is set up to provide real-time feedback analysis and observation engineering by linking predictions, geotechnics, BIM, and data from construction and instrumentation in an automated manner. Examples are provided on how the system is designed to reduce administrative time and improve productivity by enabling engineers to focus on analysis. Furthermore, the benefits pertaining to risk management, time and cost management, and communication are demonstrated.
