THE FORMER boss of Mowlem is expected to leave the company at the end of June.
Simon Vivian replaced Sir John Gains as chief executive in January last year before agreeing to a £313 million takeover by Carillion two months ago.
Carillion has already said the entire three-man executive board will go once they have helped integrate the two firms.
Mr Vivian will be joined in the departure lounge by finance director Paul Mainwaring.
But the future of the final executive director Arthur Moore is less clear, with speculation growing that he will be asked to stay on at the consortium ? called Aspire ? behind the £8 billion PFI army accommodation deal, known as Project Allenby Connaught.
Mr Moore headed the project for Mowlem before the Carillion deal was completed.
One source said: 'There's talk he might go to Aspire because of his knowledge on the job.' He joined Mowlem in 1987 and is expected to leave the company later this month with a pay-off.
Carillion is currently in discussions with two firms about selling its Australian rail business, Barclay Mowlem, as well as its environmental testing division.
