HS2 Old Oak Common: collaborative delivery of the UK’s largest new-build station

First stop on the £45 billion, 215 km first phase of Britain’s High Speed Two (HS2) railway between London and the West Midlands will be at Old Oak Common in north-west London. Costing £1.7 billion and due for completion between 2029 and 2033, the 14-platform structure is the UK’s largest-ever new-build station. This paper provides an overview of the project and the central role collaboration has played in the contracts for enabling works, design and construction, resulting in the development of a truly integrated project team.
