Murphy Group’s chief executive and strategy & business development director will leave the company this month.
Development director Colin Courtney will step down at the end of September, Construction News understands, after being appointed to the role in April 2013.
He joined the company from the Department for Business, Innovation and Skills, where he briefly worked as a construction industry strategist.
Prior to this he worked in various roles at Skanska for over a decade.
During his time with Murphy, Mr Courtney was also appointed to the industry and government-led Green Construction Board.
The news follows the departure of the group’s chief executive John Stack, who has also announced his exit from the group.
In a statement, chairman Les Dawson said Mr Stack had decided to “hand over the reins” following the restructuring of J Murphy & Sons board earlier this year.
Mr Stack joined the company as a graduate engineer in 1982 and has worked in various roles over the last three decades, spending the last six years as chief executive.
Murphy chief financial officer Matthew Behan will take over as interim chief executive from 1 October.
In March this year the daughter of Murphy Group founder John Murphy, Caroline Murphy resigned from the board of directors after eight years with the company, having voiced concerns over the future development of the business.
