Airport operator BAA has signed a deal for Carillion IT services to install a network at an extension to Heathrow Terminal 5.

Under the deal, Carillion will provide a structured cabling system at the new Terminal 5C, a seven floor building that the company's construction wing will complete in the next two years.

It will implement ADC Krone TrueNet cables, connecting to 5,000 machines. The cables will be used to supply data ranging from passenger information displays to gate desk computers and baggage handling, as well as linking to 15 stores and 12 aeroplane stands.

Carillion IT services already provides cables to BAA’s airports in Scotland, which include Edinburgh, Aberdeen and Glasgow.

Last week, BAA said it was looking for an enterprise resource planning supplier for the next 10 years, to provide work centred around Heathrow Airport.

A year ago, BAA and airline British Airways experienced severe difficulties at the launch of Terminal 5, after a failure to thoroughly test baggage handling systems led to severe delays.
