His job is to develop and negotiate large long-term contracts with customers and developing partnering strategies.
Mr Rogerson spent more than 20 years in the Royal Air Force, culminating in a stint as military general manager of London Air Traffic Centre, before joining IT firm Admiral Group in 2001 and then Serco in 2004.
At Serco he moved through a succession of senior posts including managing director of Serco's defence operations and civil aviation business and senior VP of Serco North America before becoming head of operational efficiency in 2010.
"I am delighted to be joining the Costain Group at a time when the company is transforming into a leading UK engineering solutions provider," said Mr Rogerson. "Costain has already made significant progress in developing its design and maintenance capabilities in addition to the established construction operation. We have a tremendous opportunity to establish further our presence as a broad based Tier One engineering solutions provider and I look forward to playing a major part in that process."
Costain Group chief executive Andrew Wyllie said: "Our target customers are spending billions of pounds per annum on capital, operations and maintenance contracts. Those same customers are expecting suppliers to provide broad and bespoke solutions to their specific requirements by delivering a service across engineering consultancy, construction and operations and maintenance. We want to be the first choice for those customers and Mark, with his considerable experience and success in this field, will bring additional expertise and leadership which can only benefit the company in the future."
