Carillion has won a £124m deal to build two 45-storey residential towers in Dubai for Emaar Properties PJSC

In a trading update the firm said: “In Canada and in the Middle East, we expect to double our annual revenue over the next three to five years, in each case to around £1bn. In UK support services, we expect substantial opportunities for growth as we move through 2011 and into 2012 and 2013, as pressure on both central and local government to reduce the cost of public services leads to an increase in outsourcing.”
