sites first needed to know exactly which mounting points were out of alignment. A company specializing in precision assessment was brought on board. It used lasers to draw up a map of the exact position of each of the mounting points – which revealed which ones needed to be adjusted, and by how much. The next step was to “move” the mounting points either forward or backward. To do this, Holland Composites had designed a set of six plastic caps that could fit over the mounting points already welded to the steel structure. The six caps were shaped so that they could effectively shift the position of the mounting points of the panels by either one, two, or three millimetre, either forward or backwards. Next, a team of construction workers scaled the steel skeleton, each equipped with a bag of

plastic caps and a map of the mounting blocks’ locations, and started putting the caps in place. Only now could Holland Composites begin actually mounting the panels (see Figure 5). But in order to protect their outer surfaces, the panels had to be handled with extreme care. So the team commissioned a unique attachment for a forklift, which could carefully lift each panel using vacuum clamps – just as if it was a pane of glass. This attachment could be used to position the panel with millimetre precision. Each panel had up to 15 hooks fixed to its inner surface. And all of those hooks needed to be placed over the plastic-capped mounting points at exactly the same instant. The only solution was to use a remote control

to twist and tilt the panel until it was in the exact position, before gently lowering it into place. The use of this high-precision technique was a first for the building industry. After the panels had been mounted, they needed to be bonded into one single surface. The panels had been designed so that, when they were placed directly next to each other, there was a 51mm gap between the outer skins – Twaron-reinforced resin composite laminates – of each panel. A strip of the aramid-reinforced laminate was then glued into this gap, directly onto the exposed PIR foam beneath, and bonded to the laminate skins on either side. This “bonding laminate” formed a strengthening bridge between the panels, ensuring the entire façade behaved as a single No74 July 2012

unit. The façade was almost complete. All it needed was a coat of paint. And the white glossy finish that the architects dreamed up was identical to the gleaming hull of a luxury yacht – so it was time to call in the master yacht painters. After plastering and sanding the façade, they were ready to begin. It is almost impossible to stop and start the painting process without leaving a visible stripe. So the entire 100m-by-25m façade had to be painted in one go. Luckily, the new extension is about the same size as a giant yacht, so the painters knew exactly how to go about it. They employed a four-phase painting method, which enabled them to start and finish the process per phase in one go. At one end of the façade, they installed paint sprayers at three levels – one above the other – raising them off the ground on moveable aerial platforms. These “platforms on wheels” then drove carefully along, in perfect synch with each other, with their onboard sprayers coating the façade as they went along. At last, the façade is finished. Its smooth, seamless shining white surface forms a striking contrast to the existing Neo-Renaissance building, with its densely decorated red and gold bricks. The new façade is the largest synthetic structure anywhere in the world – and it was only possible thanks to the unique properties of Twaron paraaramid fibre. n
