Following the appointment of a policy & strategic planning director in April, he has now brought in a new head of education & training, a head of economic analysis and a head of policy & research.
Mr Belton said the appointments would help the CITB “to meet the changing needs of the industry”.
Graham McPhail will join as head of education & training next month from Hartlepool College of Further Education, where he is director of curriculum.
Geeta Nathan, previously of Fleming Capital Management and the UK Government Economic Service, joins as head of economic analysis.
Gillian Econopouly joins in December as head of policy & research. She is a former head of policy at the London Chamber of Commerce.
As previosuly reported, Steve Radley joined CITB from the Engineering Employers Federation in April as policy and strategic planning director.
Mr Belton said: “Construction is facing a perfect storm of opportunity. New technology and ways of working has the potential to revolutionise how we work and CITB must be at the sharp end of this change – working with industry and governments to help businesses in the supply chain to gain commercial advantage.”
