Rosemary Beales, the national director of the Civil Engineering Contractors Association, is to step down from her post at the end of March.
Ms Beales has been at the association since it was established in 1996. She is expected to take on consultancy and non-executive roles within the industry.
The process for recruiting her successor is still being determined.
Ms Beales said: “I remain extremely proud of my role at Ceca and everything we have achieved. I believe Ceca is an active, positive and influential part of public life in the United Kingdom and will continue to provide leadership to the construction industry.
“After nearly a decade and a half in post it would be impossible not to have grown strongly attached to the organisation and the many people I have had the privilege of working with throughout that time, both staff, members and the many others who make up our industry and its clients. I want to take this opportunity to thank you all for the support I received during my time as national director and to formally wish you the very best for the future.”
Seamus Keogh, chair of Ceca National, said: “I know that everyone involved in Ceca, past, present and future, will join me in offering our most sincere thanks to Rosemary for the exemplary service she has performed both for Ceca and the construction industry as a whole.”
Bam Nuttall chief executive Stephen Fox added: “Thanks to Rosemary’s leadership, Ceca is an asset to the industry. I wish her all the very best for the future.”
Construction Products Association chief executive Michael Ankers said Ceca had played a central part in the development of “a strong and united voice for the infrastructure sector”.
