David Polkinghorne

David Polkinghorne is currently Design Manager for the Sydney Metro City & Southwest Tunnel and Station Excavation (TSE) Project, a joint venture between CPB Contractors, John Holland and Ghella.  He commenced with the John Holland Group in 1978 after graduating from the University of Melbourne with first class honours.  He has progressed within the company to become one of its most experienced managers and has held senior positions in the delivery of major infrastructure projects with nearly 42 years’ experience in design and construction. His experience includes the WestConnex 1B, Sydney Metro Northwest Tunnels (TSC), Glenfield to Leppington Rail Line, Lane Cove Tunnel, ANSTO Replacement Research Reactor, Prospect Water Filtration Plant Structures, MCG Southern Stand, 530 Collins Street, Reliance Rail Project, the Friendship Bridge between Thailand and Laos and the Homebush Sydney Showground.

David has a proven track record in managing the design of diverse, multi-faceted projects to achieve quality, cost and time targets. He is experienced in forming and leading teams that include design management, construction techniques, multiple contractors and trades. This has required a high level of communication skills, extensive technical expertise as well as a sound knowledge of industrial relations and the OHS&R Act.  Further to this, David has direct experience on the use of concrete in all its forms and the important role the material plays in the delivery and management of infrastructure. Challenges experienced with the design and construction of concrete on major projects are issues he has extensive experience with.

In 2016, Engineers Australia awarded David the “Australia Civil Engineer of the Year” for services to engineering and the community.
