• A highly successful PFI project completed ahead of programme and well below budget.
• A technically complex twin tunnel bore beneath the Thames and the challenging interface with existing rail lines and station made this a very difficult project to deliver successfully.
• The fully integrated team benefitted greatly from working together on previous projects.
• Strong community interface resulted in public satisfaction with the outturn.
