THE DEVIL IS IN THE DETAIL: A MANUFACTURER’S PERSPECTIVE The UK construction industry is continuing to weather the impact of the coronavirus pandemic but is still facing ongoing challenges when it comes to design detail and the specification process. All too often, information is missing from drawings, leaving decisions to those on the ground, who may invariably take the opportunity to reduce costs by substituting products. This can lead to a loss of design intent and quality. However, it doesn’t have to be this way. How then can manufacturers play their part in the specification process and ensure that value engineering is not simply cost cutting at the expense of quality – but rather, a method of ensuring the client gets the best possible value for money with products that improve the functionality and quality of the project?

n her report, ‘Building A Safer Future’, Dame Judith Hackitt said that the term ‘value engineering’ should be driven out of construction, saying that she would be “happy to never hear [it] again”. The term has divided the industry because simply reducing cost at the expense of quality is not value engineering. The process can, in some instances, involve substituting or swapping quality products for cheaper

and inferior alternatives that do not meet relevant industry standards because seemingly they appear ‘better value’. In the long term, this can compromise the overall effectiveness of a building and have more serious implications in terms of fire, health and safety. Product substitution should only occur where there is a clear comparison in performance against the required specification.

In its simplest terms, true value engineering is problem-solving, which is why the relationship between building product manufacturer and specifier has never been more important. At Leviat, one of our core values is customer focus that we express as ‘we put our customer at the heart of it all’; this means we are committed to understanding and achieving their vision. We will review an engineer’s or architect’s principal concepts and advise the suitability of products, highlighting any design concerns early so they do not become costly surprises later in the supply process. A well-engineered and -understood product will add value and not cause a contractor issues during installation or the building owner during its lifecycle. Whilst being able to provide a range of standard products which specifiers can select to a set performance and criteria is part of what we do, a large part of our work is ‘designed bespoke’ to overcome engineering challenges. In other words, we will take a standard product, adapt it for a project and then ensure it is fit for purpose. This was the case on a project in Nightingale Place, south London. In order to help the customer avoid the need for additional restraint fixings into the post-tensioned (PT) slab and the use of expansion bolts into high-stress zones, we created a stiffened channel to the underside of our brackets allowing flexibility of the joint position. In short, all our designs start from the principle of providing an engineered solution that the customer will be confident safely delivers the performance aspirations for the project. Each project is unique in its needs which is why many of our product innovations are driven by our understanding of frequent design demands in complex projects or novel solutions to unusual design challenges and then offering that new product solution to the wider market.
