The £1 billion home for Heathrow's 20 million Star Alliance passengers has moved a step closer, as BAA signed its largest ever construction contract with HETCo, a joint venture between Ferrovial Agroman and Laing O'Rourke. 

Crown House Technology, a Laing O'Rourke subsidiary, is working on the Mechanical & Electrical elements of the project, and has chosen to use P1 mobile technology for tracking and quality checking the installation of off-site manufactured modules for the building structure.
