Too much of what we have built in the last 10 years is fit only to be torn down - Andrew Mellor, PRP


​There has been much discussion in the industry in recent years about poor-quality construction and the impacts this has on architectural aesthetics, building performance and occupant wellbeing.

​There has been much discussion in the industry in recent years about poor-quality construction and the impacts this has on architectural aesthetics, building performance and occupant wellbeing.

I have had direct exposure to construction quality issues since the Grenfell tragedy as we investigate the compliance and safety of residential buildings and I am afraid to say there are numerous examples of very poor construction quality out there.

Where defects are found in residential buildings they seem to apply to buildings that have been built or had major refurbishment work within the last decade. Some buildings are so poorly constructed that there will be no option but to demolish them in whole or in part and then reconstruct. Put simply, they are not fit for purpose.

The failings do not just relate to fire safety issues. Other failings relate to structural fixings, thermal performance, weatherproofing and durability, which have potential safety and health impacts as well a clear potential for premature degradation of the building fabric.

We have witnessed the consequences of this poor quality: facade panels falling from height, rapid fire spread to adjacent dwellings, internal mould growth, material degradation and inability of buildings to adequately retain heat and prevent solar gain ingress.

Those that occupy poorly constructed buildings are very typically innocent victims. They have usually had no formal part in the design, procurement and construction process, yet it is these tenants, leaseholders and owners who are directly affected by the actions of others.

Building owners of course have to deal directly with these matters, with the attendant cost in time and money. Morally, they should not be liable for these failings given that the building should have been built properly in the first place.

Building defects will always occur, just like defects will always occur in products from other industries. But what is becoming evident is that this is becoming a potentially much bigger issue for the construction industry than a standard product recall.

So why has this happened? There are of course many contributing factors but the competence of all involved and the drive to build cheaper are, in my opinion, two of the main factors. This is exacerbated by a regime of quality inspection on site which, pre-Grenfell, was at an all-time low in modern times.

Competence is a combination of expertise and experience. Without knowledge of why something must be built in a certain way, and the impacts of not doing so, designers and construction workers cannot possibly contribute to the building of high-quality safe buildings.

Training must therefore be part of the solution, but so must be a realisation that oversight is needed in the form of site managers who fully understand construction detailing and regulatory-compliant solutions, as well as the use of quality inspections at all stages of the construction.
