Towards Integration of Engineering Services at Crossrail Stations, Shafts and Portals

Summary

Construction of Crossrail is made up of discrete work packages for Stations, Portals, Shafts and Tunnels works plus a number of line wide railway system works (trains, tracks, signals, communication, power transmission, fare collection, platform screen doors and tunnel ventilation). A unique integration process was developed to meet the working environment for a mass transit passenger transport system. A vertical integration assurance process is adopted to ascertain that all system elements are fully co-ordinated and integrated to perform as a single integrated entity meeting all functional requirements, recognising that they are designed and constructed under different work packages. This paper provides an overview of the building blocks and their interactions for the integration process at Crossrail stations, shafts and portals.
