Voskuijl and De Wilde Metaal B.V. have succeeded in working out, calculating and building the complete Eurovision stage in a very short period of time. De Wilde Metaal is able to operate in a very wide range of steel and aluminium structures. This is achieved through the versatility of its staff and machinery. Their customer based and flexible approach allows them to advize their clients at an early stage, leading to a very high-quality end product. Set for the European Song Contest 2015, “Wiener Stadthalle” - Vienna, Austria SE Owner Austrian broadcast corporation. ORF Architect Wieder Design München General Contractor De Wilde Metaal and Unbranded Set building Engineering Office Ingenieursbureau J.C. Voskuijl Construction Period 03/2015 - 04/2015 The stage of the 2015 Eurovision Song Contest consists of about 1,300 individual pillars and measures 44 m in width, 14.3 m in height and up to 22 m in depth. Each pillar has an LED at the front end and can produce a wide variety of lighting effects. The pillars (aluminium tubes of 203 mm) are held together with steel stud ends in a smaller aluminium tube. The construction was manufactured in parts in Bilthoven (the Netherlands) and put together in the Wiener Stadthalle in Austria. The stage was designed in a CAD program, and exported as an IFC file. This file was imported into SCIA Engineer. After a few steps it was possible to apply loads (service weights and a small wind load) and make loading combinations. The aluminium control gave a quick view of the beams which had to be reinforced. The construction has several supports on the floor. The top part of the stage is connected to the ceiling with steel cables. The reaction forces from the SCIA Engineer output were sent to the stage builders. Ingenieursbureau J C Voskuijl
