On 24 August 2015, the building contracts were awarded for the western section (Ealing to Hammersmith: £416 million, to BAM Nuttall, Morgan Sindall and Balfour Beatty), the central section (Hammersmith to Tower Bridge: £746 million, to Ferrovial Agroman and Laing O'Rourke) and the eastern section (Tower Bridge to Stratford and Greenwich: £605 million, to Costain, Vinci Construction Grands Projets and Bachy Soletanche).
