You will hold an appropriate construction qualification (ONC/HNC/HND or equivalent) and have a minimum of three years’ experience on fast-track motorways, trunk roads or similar highways projects. You must have proven people- and resource-management skills, a good working knowledge of health & safety and HR procedures, experience with NEC/ICE or MAC contracts, and a full clean driving licence. Strong leadership, planning and communication skills, commercial awareness, problem-solving ability and flexibility are essential. You should be a team player, results‑driven, conscientious and committed to continuous improvement and high standards of safety and client service.
