THE COMBUSTIBLE CLADDING CRISIS - WHO IS TO BLAME?


The date remains unclear; which project was it? It must have been over twenty years ago, possibly more. The circumstance should stand out as it was a product that was not frequently used in my projects. The classy, slick cladding was the friend of those seeking the 'high-tech' image that produced a smarter, more shiny, 'modern' technological identity than that which others concerned with different, less strident issues, desired. This more commercial, promotional, self-important identity also made the product identifiable as a flash skin applied for branding, to make a mark. It was a material that could ‘fake’ any shambles, transform it into a sleek, fashionable, technical wonder, a fabulous world of make-believe that was literally skin deep.

Because of the unfamiliarity with the product, its available finishes, detailing, and fixings, the rep was asked to come in for a meeting. He was a good rep for his company, being knowledgeable, thorough and helpful. He was able to respond with precise and factual detail on all matters, answer all questions, explain the issues involved, and expand on the possibilities available. It is always a pleasure to work with such individuals rather than those that act like the proverbial car salesman.





Towards the end of the meeting, the rep added a caution that was by no way a threat or a blunt, coercive sales pitch. It was more helpful advice, as he knew I would be exploring all options. He did not assume that his product would be used. "Be careful of the cheap copies. Our product is expensive, but it has been tested for fire. All the cheap copies are flammable. They use a polyethylene filler; ours is a phenolic resin that does not support combustion."#



This advice has always been heeded, and has been passed on to anyone who might listen. It has been a basic stand taken on the principle that one should know what one is getting. There are some copies of products that are of equal quality, and can happily be used as alternatives; but where there is a vast discrepancy in performance in products that look almost identical to the casual eye, one has to be firm, and insist on getting what one wants. The proposition is that if I, a minor user of this cladding product, have been told of the problem with cheaper, flammable copies of this material, many others in the industry must have known too. No doubt the rep would have told as many others as possible too, anyone who would listen.



So how did it happen that the cheaper, flammable product found its way into general usage? One can guess that this perhaps involved the unquestioned turn of ‘blind eyes,’ and the ambition for bigger profits, excused, maybe, by some aesthetic or practical benefits. The cheaper flammable copy looked much the same as the original product. From memory, it might have had some perceived ‘advantages’ too, other than price. Was it the choice of finishes, the sizes and thicknesses available, properties that only benefited budgets too, or added a little 'icing to the cake'? Maybe it was the propaganda, the glitzy promotional material? One can remember the bigger and brighter publications pushing one particular cladding product.





Can one hypothesise that unscrupulous contractors swapped the cheaper item for the specified product without anyone knowing? This might be possible, but the product does come with a protective plastic sheet that is printed with the product's name as a surface pattern. This protective layer is left on the sheet material until the installation has been completed, a little like stainless steel. This means that it would be very unlikely that the secret 'swap' with the "I did not know" excuse, would be the cause for any particular use. The printed protective skin makes it clear just which cladding is being used.








It seems more likely that the 'save money' strategy might be the reason. Here a contractor might come back to a client with the proposition that, if product B is used instead of the expensive specified A - “Architects!” - then a saving of x thousand dollars could be made. This proposition is always attractive in projects when little unknowns start putting pressure on budgets. With the cladding being one of the last things to be installed, it would be a time when project costs were becoming clearer.



"You'll never know the difference," is the common statement made at these times. Unless there is someone there willing to argue for, to insist on the fire resisting properties of the more expensive product, the swap is usually happily approved, perhaps without the lack of any difference in fire performance being revealed. There is, of course, the situation where good advice will be over-ridden too, when the contractor's and the client's ambitions align - “Architects!”.



The other likely reasons for use of the flammable product simply involves designers and developers trying to get prices down and specifying/using the cheaper item, just because it looks the same and costs less. “Why waste money on the more expensive product?”



Somewhere in all of this stands the certifier. Whether this was the local authority or a private alternative, (the time period stretches beyond the change to private certifiers), someone must have approved or signed off the use of the cheaper, flammable product. Was it out of ignorance, or with a vague, hopeful, carelessness? Did the regulations prohibit the use of flammable products? Maybe not. The rep knew the problem, but it was easy to see this as a sales argument that gets a dismissive response something like: "He would say that, wouldn't he? He’s a salesman." Given that certifiers have been known to quibble about millimetres, one should assume that they knew what they were doing. It would be terrible to even think or believe otherwise.



The situation today clearly reveals that the ‘benefits’ of the cheaper product are illusory. That owners/residents are being asked to fund removal and replacement of the cladding can be understood, especially with the urgency stimulated by the Grenfell Tower disaster, but it does beg the question of responsibility. How did this mess happen? Was it really from ignorance? Was it a matter of commerce, where habit forgot the problem and pushed on doing what everyone else was doing?


It takes only one example to set the scene: "What's your problem? They used it on project x; and the government project y too; and they should know, shouldn't they?" When the snowball starts rolling, it is difficult to stop, especially when savings are involved, appearances are nearly identical, and certain reps are persuasive. Could it have been a matter of muddled associations? "They used it on the xyz fascia," that just happens to be an award-winning project that has been well published, a project where fire performance was not critical. So again, the image and idea catches on as the scale and context of use grows. "Why not use it here," could be the question, underlined by the ambition to gain all the kudos given to the winner? Might this be the sub-text?




One can recall how these products were promoted: all companies produced impressive, stunning, coloured, glossy publications illustrating the smartest and slickest, the most desirable images possible. That there was a stark difference between the performance of flammable products and non-flammable products, is something that was, on recollection, never given the same hype. It seemed that one had to be told.



There is no one answer for responsibility. Each circumstance needs to be assessed in its own special context. This sounds like a ‘cop out,’ but it is so. Building regulations of the particular time need to be reviewed as a first step. If the flammable product was ever allowed to be used without any recognition of its flammability, then legislators need to explain. If the circumstance has been all about budgets, then the finger starts swinging. Why was it allowed? Who gave it the tick? Projects are supervised and certified for a reason. Is it too easy to overlook an impressive, slick finish when attention is given to the millimetres of handrails, steps, waste outlets, disabled access, and set backs? Or did rigour with the understanding of materials and their properties just get forgotten in favour of aesthetics and prices?



As soon as Grenfell was seen burning, it seemed clear what the problem might be. The words of the rep returned, "Be wary of the cheaper, flammable copies." Was it that somehow, over time, the care faded and some other driving force took over? This is a lesson for all - know your products and properties, and never fail to take a responsible stand to ensure that the specified qualities are adhered to. Shortcuts and savings often turn out to be onerously otherwise. Everyone needs to be aware.


Unfortunately there is another question to be asked: were the sales rep for the flammable product as rigorous and open in their promotions as the rep that I spoke to? "He’s their salesman. He has to say that!" might have been the response. Some sales folk are unscrupulous. Folk can become engulfed in the euphoria of presented possibilities and forget to ask the critical questions.



It is the responsibility of the user or the agent to demand answers to probing questions to seek out the facts. Unfortunately, today the tables have turned. Professionals are asked to attend point-scoring sessions to listen to sales pitches: see https://voussoirs.blogspot.com/2019/02/whats-point-on-re-registration.html  Blame for the flammable situation will be like a ball, bouncing around from one to another. Hopefully it is caught before it stops bouncing and rolls away, to be picked up by another concerning mess.



Thinking about the situation in the Australian context, it seems that the first step is for government^ to determine whether the use of the flammable product was in accordance with all appropriate regulations of the time. If so, government has to explain this situation. If the product  was not in accordance with the regulations, then it seems that it is up to government to discover why the product got used and approved. Government may be keen to pass responsibilities onto private bodies, anyone else, but even this flick is in its control. It is too easy to issue letters of demand and stand aside. If the product has been wrongly used and approved, it appears that it is finally up to the government to determine why, and what action must be taken to manage the lack of responsibility, and determine ways to remedy the situation. It is, after all, the government that manages laws for construction. Coming in after the event to issue demands for remedies seems somewhat inappropriate when the government is setting up the processes and systems for others to supervise, manage and comply with. If these arrangements have failed, the government needs to discover how and why. Who knows what else has been allowed? What must be done to ensure not only the cliche 'so that it will never happen again,' but also to find out who might be responsible for any penalty and remedy. Someone let it happen in a world that has rules, regulations and much supervision. It is surprising to see third parties that have purchased these properties being asked to correct matters.*


# The precise description of the filling materials needs to be checked, but this was the gist of the conversation.

^ 'Government' is used here as a generic term for the governing body, the authority that sets the rules and manages compliance, or licenses others to do this.

The surprise in this article is that the option to not use the flammable product does not appear to be considered. Perhaps the proposition is that fire breaks could be inserted into existing facades to limit spread; but what/how? Sprinklers have been used, but such systems have always been considered expensive. The Grenfell disaster changes this perception. The irony here is that it seems that the flammable material itself is generally used to save costs.
