As I have a friend who is a surveyor who specialises in this field and has been telling me where the Grenfell builders and owners went wrong, I happen to have a fair idea of where things went wrong and continue to go wrong.
The answer (according to my surveyor friend) is a culture of sticking plaster.
The laws around buildings are a myriad array of sticking plaster measures, some even contradicting others! Every time something happens, say an electrical fire - some Herbert drafts a new regulation or a must-have certificate that does nothing to redraft or even alter the existing laws. The result is the legal equivalent of a dying patient covered in small bits of sticking plaster. Silly footling rules for everything, but no overall concept.
Putting cheap PU boards with wooden frames covered in aluminium on the outside of a building is a sticking plaster measure. It was cheap and quick and even looked sort of nice. The right way is to renovate the building on the inside and insulate every flat on the inside and provide proper fire escape exits and other measures. That would entail moving every tenant out and finding them all alternative accommodation. "Ah, F-it! Just stick some cheap cladding on the outside and that's that box ticked!"
More sticking plaster!
Story -
I managed to tear a ligament in my shoulder over the weekend whilst playing with my Great Dane. With great trepidation, I went to our local GP practice on Monday as the pain was getting worse. There, a remarkably pretty young female GP sent me straight to the local hospital.
(A few years ago, that hospital came in for huge criticism for having bad management and management practices and was forced into a root-and-branch reorganisation. The whole place was totally difunctional and chaotic. The old guard were shown the door!)
Half an hour after talking to that GP, I rocked up at A&E and they knew that I was coming. They ushered me into orthopedics and I was x-rayed and the consultant examined me and a nurse put my arm in a sling and just half an hour after coming in, I was sent home - all fixed up.
Yes - even the NHS can be made to work! But it took a root-and-branch reorganisation to achieve this!
And that is what is required with building regulations. Throw the entire chaotic blizzard of silly rules and pointless certificates out of the window and put in understandable regulations that do not contradict one another.
Some of those rules are antiquated nonsense and some are even dangerous - a typical example would be the ring mains rule, which was introduced to save copper during the war years. It is not only dangerous but also completely pointless!
In terms of ‘Disasters’ I put Grenfell in the same category as Concorde! Most aeroplane crashes are caused by a series of events. In the case of Concorde, Runway Debris was the ‘Primary Cause’ however, there were other contributory factors that led to the ‘Crash’ itself – A substantial delay, additional passengers, their luggage, a change in wind direction (uncorrected), the maintenance of the front wheel assembly, and the decision of the pilot to shut down the port engine, during rotation.
Investigations and Inquiries have concluded that ‘Fault’ lies with the maintenance of the aircraft that used the runway BEFORE Concorde, and deposited the debris.
Grenfell used materials that many considered ‘New’ – However, they were NOT new at all. The Composite Cladding Material and the Insulation had been in use for 20 Years or more. Yet in the case of Grenfell and many other ‘Retroclad Buildings’ it was more about the ‘HOW’ the materials were used together.
Long before Grenfell, there had been other fires, where similar construction techniques had been used – Particularly in the Middle East. The ‘Fire Characteristics’ were INDENTICAL. In the case of the Middle East buildings there was a lack of ‘Fire-Stopping’ and Compartmentation – In my opinion, the same occurred with Grenfell. Without such containment measures a ‘Chimney Effect’ occurs. Fire and Smoke travel upwards in the Void Space between the Exterior Cladding and Insulation/Structure, and the fire travels rapidly - Fuelled by the 'Eddy Effect' on High Rise Buildings.
The Building Regulations already deal with Fire-Stopping and Compartmentation (and have done so for several decades). However, I would suggest that either it was NOT INSTALLED, OR it was INADEQUATE!
From a construction aspect, Fire-Stopping is a ‘Pain in the Arse!’ – It usually requires further Specialist Trades, and is time consuming. Thus, extending The Main Re-Cladding Operation, and affecting ‘Attendances’ such as Scaffolding and Temporary Works, etc. Although seemingly insignificant to the layman, Fire-Stopping could have doubled the duration of the Cladding Operation, and would have impinged ‘Cumulatively’ on other aspects of the Construction Programme.
Such operations also rely upon a close level of Supervision and Inspection – I very much doubt whether the Main Contractor and the Building Inspector clambered over the external façade as work was being carried out? Indeed, the ‘Smart and Clever’ organisation of Contractors, Sub-Contractors, Consultants, Sub-Consultants, Suppliers and Manufacturers, led inevitably to many ‘Gaps’ being excused by
“Not my job, Guv!”
Many would question WHY a Photographic Archive was not created? Quite possibly, this would have been a further ‘Gap in Responsibilities’ or not requested at all. However, it is worthwhile noting that PHOTOGRAPHING ALL WORK associated with the placing of ‘Thermal Insulation’ is now a requirement of the latest amendment to the Building Regulations! – Pangs of Guilt?
