UK airports operator BAA has begun a £250m IT roll-out at London Heathrow's new Terminal Five.
BAA and its four principal IT suppliers have until September 2007 to deploy IT systems ranging from an IP network to a £50m baggage handling system.
Terminal Five is using Sonic ESB as the basis of a service oriented architecture, which will integrate operational systems at the terminal.
The SOA will focus on managing the interactions and changes of state as millions of messages are triggered between baggage handling, passenger information and flight information systems in relation to real-time events.
NTL Business is rolling out a fibre optic IP network that will provide the infrastructure for 200 systems and applications, including passenger management systems, a baggage handling system and an all IP CCTV infrastructure, including dedicated storage.
Nick Gaines, BAA's IT director for the Terminal Five project, said, "The technology systems represent the largest risk to our success." But he added, "The success of the project depends on sustaining one team and keeping open and honest communication at all levels."
BAA, NTL Business, Arup, Ultra and Honeywell are testing the interfaces between different systems before deployment.
