Severfield has confirmed that chief executive Ian Lawson will leave his post permanently in March, with Alan Dunsmore taking the top job full-time.
Mr Lawson stepped down from his post in March last year in what was, at the time, a temporary move due to ill health.
Mr Dunsmore, who has served as finance director for the structural steel specialist since joining in 2010, took on the interim chief executive role, but that change has now been made permanent.
Non-executive chairman John Dodds said: “I would like to pay tribute to Ian Lawson’s tremendous contribution to the Severfield business since his arrival in November 2013.
“He has been the architect of the group strategy, setting the target of doubling our underlying pre-tax profit by 31 March 2020.
“Under his leadership Severfield is well on track to deliver against this important milestone.
“Ian leaves with our thanks and best wishes.”
In 2016 Mr Lawson set the goal of Severfield doubling its underlying profit before tax to £26.4m by 2020.
In its most recent results for the year to 31 March 2017, underlying profit had increased 50 per cent to £19.8m on revenue of £262.2m.
During Mr Lawson’s tenure Severfield carried out steel work on a number of high-profile projects, including Tottenham Hotspur’s new stadium and the extension to the Main Stand at Liverpool’s Anfield ground.
In 2015 Mr Lawson told Construction News that the company had handled the problem with “integrity and honesty”.
Before joining Severfield Mr Lawson worked for Kier for 13 years, including as director for the group’s regional construction business.
