Meet The Board


A-one+ emerged as a UK leader in highway engineering inside its first 10 years. That success has continued into our second decade thanks to the vision, diligence and commitment of our highly experienced joint venture board of directors.

Representatives from each parent company are Mike Birch and Jon Harding from CH2M, David Craik and Mark Overton from Colas and finally Simon Ellison and Adrian Bennett from Costain. All bringing vast experience, stability and support to the shared venture.

A-one+ Managing Director, Clive Leadbetter and Commercial Director, Richie Youds represent the company directly as part of the joint venture board which meets regularly to govern and make collective strategic decisions.
