United Kingdom

“HS2 has made Britain a laughing stock in terms of its ability to deliver big infrastructure projects, and it has to end. This will set out the way we will do that,” a source told the PA news agency.

Infrastructure is not “the new rock ‘n’ roll”. However, if it were, then with a seminal project management playlist ranging from Heathrow Terminal 5, via the Olympic Park and Crossrail, on perhaps towards Thames Tideway Tunnel and the HS2 high-speed rail link, the best of British is fast becoming a greatest hits for the 21st century.

Recent project history has placed Britain in a unique position of global influence, according to Professor Andrew Davies at University College London’s Bartlett Faculty of the Built Environment. “Over the past decade or so, the UK has transformed the way megaprojects are delivered, moving away from a world of fixed-price contracts, risk transfer, lowest-cost tendering and adversarial relationships,” he says.

For Professor Davies, who specialises in the management of projects, the market has witnessed the emergence of a “flexible megaproject delivery model”, initiated by Heathrow’s T5.

“The UK has created an institutional environment for delivering megaprojects in a radically new way. The United States and many European countries are watching and learning,” he says.

I'm not entirely convinced that either the "everyone is sitting in awe at the feet of the master" or the "we're a global laughingstock" statements about HS2 are quite true.
