At Balfour Beatty, Geddes looked after a number of manufacturing facilities, frameworks and projects for clients including Network Rail, Transport for Wales, Transport for London and others in the private sector.

He has also held leading roles for several significant infrastructure programmes including Crossrail, Hinkley Point C Marine Works and the Olympic Stadium transformation in a long career with Balfour spanning more than 17 years.

Geddes will support Costain’s strategic focus on growth in strong markets. His appointment comes after a successful period of growth for Costain’s transportation division.

Costain recently announced two significant contract awards for HS2, including a £400m contract to deliver tunnel and lineside mechanical and electrical systems as well as a separate award to deliver high voltage power supply systems across the entire line, worth in the region of £300m to the Siemens Mobility and Costain joint venture.

Jonathan Willcock, managing director of transportation at Costain, said: “UK rail infrastructure is critical for creating a sustainable future and driving UK prosperity through improved productivity, greater connectivity, and job creation.

“But it faces challenges around resilience, particularly with rising demand and more extreme weather. Alistair brings a wealth of experience that will support our rail sector growth as we continue to deliver the strategic needs of our customers.”
