I can't think of any commercial enterprise more regulated than the building industry. There are so many hurdles to jump with just about every item of a contract, so why on earth is it so difficult to point the finger at the sequence of events which eventually lets a builder on site to do the work.
The Client briefs the design team, they follow the rules, and the builder tenders for the work.
Eventually, it's job done, so it's not beyond the wit of man to realise that probably the architect and maybe the engineer needs good talking to.
Forget silly old berks like Corbyn and that idiot Lammy, trying to blame it all on someone in government and poke political fingers at all and sundry, it's the 'professionals' who are at fault.
I hope there are building inspectors and council officials having uncontrolled bowel movements everywhere, especially up in London.
