Martin Pitt, previously commercial director across both construction and infrastructure divisions, has now left the business.
The roles of Andy Fookes, previously commercial director for the London region, and David Diboll, construction director for London, have been placed under consultation.
This rejig follows the exit of London managing director Tony Dixon two weeks ago and the appointment of Ian Cheung.
Cheung will now head the London, South East and South West construction business units which have been merged into one.
Morgan Sindall said it had identified the need for increased senior commercial resource as it gears for growth.
Sharon Chrippes, previously heading up the commercial team in the north of England, has been promoted to a new role as commercial director of its Construction and Design division.
She will report to Pat Boyle, managing director of Construction and Design.
Also Morgan Sindall is now on the hunt for a new commercial director for its Infrastructure division – when appointed, the individual will report to Nick Fletcher, managing director of Infrastructure.
Pat Boyle said: “In ensuring we are both efficient and effective in our management teams, it makes sense for us to streamline the South and South West construction business units into one, which allows for clearer reporting and better use of our experience, resource and market intelligence.
“Ian Cheung, myself and the team are excited about the challenge and opportunities ahead. We are also delighted to see Sharon promoted – she will bring a lot of insight and fresh drive to the role in Construction and Design.”
