For decades infrastructure sector clients have waged a battle to improve the supply chain’s woeful design and construction productivity, driving down costs and accelerating delivery times. 

But In reality, more effort should be focused instead on the drive towards better overall asset performance and achieving better overall economic and social outcomes. How can this focus be switched?

To discuss this issue, my guest is Andy Mitchell, chief executive of Tideway, in charge of building the £4.3bn 25km super-sewer beneath London, one of the UK’s largest current infrastructure projects. Andy was also, until recently, co-chair of the Construction Leadership Council, playing a key role in helping the sector to work with government to improve.
