Let's not go down this route suggesting the cladding was anything but a cosmetic upgrade to appease many of the surrounding residents (who thought the old 70's concrete block was an eye-sore). Their is even documents suggesting this was the real/main reason!

Ok you need to consider this with a slightly less emotive perspective (difficult I know). But when many residents are asked what upgrades they would like to see, Aesthetic improvement comes very high on the list. People want to feel proud of where they live and its a fact that visible improvements come hand in hand with a reduction in crimes. Now you might be correct in that the works were initiated because of visible impact of the surrounding area, but we don't know.
Secondly reducing heating bills is something that is also very high in occupiers "wish lists" and under UK law you can not over clad a residential building without increasing the insulation levels. The reason that cladding used is because in comparable terms its a very lightweight material and more often that not 50's and 60's concrete towers were built relatively close to their structural limits. On the office block over clad projects I've been involved in our choices were very limited due to loading issues on the existing concrete frame / spandrels.
Something has gone spectacularly wrong here though, it went from the fourth floor to the eighteenth in under 10 minutes, that is so unusual that the cladding might not be the only reason that it spread so fast. Again though it's not known until the investigation is complete.
Of course not, but you would think they would be robust enough to ensure a small fire caused by a fridge in a single apartment out of 240 apartments would not completely annihilate the building when correctly followed.
Our regulations are very robust but something that we have spoken about for years in the office is how long it takes in the construction industry to change legislation in reaction to live scenarios. If you compare the industry with something like the aviation industry, we move at almost glacial speeds. In a air disaster there is an investigation, the findings are then rolled out by the Aviation authority and within weeks / months those changes are live, in the construction industry it can take years!
This is for one reason only, the building regs are an Act of Parliament and anything involving government takes an incredible length of time complete and they often become political (as this case is clearly showing).
What has been needed for years is an independent body (like the aviation authority) to take control of the construction industry, with the authority to make changes faster than the house of commons, in response to expert testing.
The fact is this report has been sat on because politically it was a time bomb in a time of government led austerity. It would have been a political disaster to have forced the cost of additional upgrades on to strapped LA’s, and people have died for it.
