His departure follows John Stanion’s retirement and the appointment of Bruno Dupety as new chief executive last week.
Ridley-Barker, who left at the end of last week, was with the firm for 13 years, first as a divisional director of the Taylor Woodrow for over six years and then operations director at Vinci UK.
He was managing director for UK construction for nearly four years.
The Vinci Construction UK business has been battling to turn around the building division, after it posted a £33m loss in the last published results for 2013.
