Reform have previously indicated they will cancel all such projects if elected
Good thing we have 4 or so years to get a move on
And this is another reason why we have dysfunctional infrastructure project delivery. Thanks, Nige (and politicians in general).
There is a credible threat of cancellation, so clients rush to get contracts awarded and the project past the point of no return.
Seeing this, objectors step up their opposition because if they can hold on just long enough, the new guy has promised to cancel the project and leave their back yards unspoiled.
Their objections delay the project and costs start to increase.
Supply chains get uncertain about if/when the project will be delivered, so they hold back on investing in people, plant and processes, setting themselves up for inefficient delivery.
It is too risky for them to take on the job with a fixed price element because they could get wiped out by delay, so it gets done using another model with cost-plus elements, meaning they may in fact benefit if the project takes longer and costs more than planned.
So we have an immature project, starting late, with contractors who may not have all the breadth and depth of capabilities they need to deliver the scheme, who may not be that motivated to deliver to time/cost.
Shovels go in the ground, unexpected is discovered, costs pile up, delays accrue, commercial managers rub their hands as contract variations are priced.
The project is curtailed, half-baked because it has become politically embarrassing to some future leader.
UK demonstrates it has learnt nothing from HS2 and other major projects. The year is 2045.
TLDR: It's not just about throwing lots of capital around at worthy schemes, it's how Government sets itself and the country up to deliver what has been promised. Has the Chancellor said anything about that?
