  • Dear Readers,

    The term “shutdown” is really not the best choice of word for describing what our customers and we do during a major turnaround. The only thing that has been shut down is the facility itself – everything else around it is a hive of activity. In fact, work begins months before a shutdown is due to take place as everything has to be meticulously planned and organised and all possible parts produced in advance so that the plant can be up and running again in as short a time as possible.

    BUCHEN and XERVON took part in two major shutdowns earlier this year – both at the same time. All in all, the two companies deployed around 1,200 employees over this four-week period to carry out a whole range of different tasks. Very few companies in Germany are able to take on such a mammoth project. Read our feature article to find out how we succeeded in doing this.


    Brand-new technological developments

    Another thing that creates a hive of activity at our company is our desire to solve our customers’ problems and find bespoke solutions that meet their exact requirements. We are constantly working on further improving our services by developing technical innovations that make processes even more efficient. We have come up with a number of smart ideas for a range of different applications. From closed loop processes, to getting maintenance work fit for the future with condition monitoring, all the way through to creating our own complex technological developments such as the dense phase conveyor system and our very own industrial cleaning robot, the automated industrial cleaner (AIC).

    No matter what development we may be looking at, our focus is always on improving workplace safety. As a result, we have launched a variety of product innovations onto the market recently that makes working in boilers much safer. We have also been awarded a number of work safety prizes from our customers – demonstrating that this subject is just as important for them as well. And we are happy to admit that we are extremely proud to have been awarded these. They are proof that our ongoing efforts to improve work safety are bearing fruit. Whether it be RWE, EVONIK or Covestro – to name just a few – they have all commended us and thanked us for the hard work we carry out in this area. We, too, would like to say a big “thank you” to them: for giving us these awards and giving us the opportunity to work with them. We are also doubly proud because we operate in such a wide range of fields, all of which – such as tank cleaning work – have their own particular hazards and risks. Our experts are in high demand both for onshore and, in particular, offshore projects. From the North Sea to the easternmost region of Russia: our customers like to make the very most of our in-depth know-how and specialist technology.


    Outstanding scaffolding services

    What’s more, the latest scaffolding projects in Sweden and Austria clearly demonstrate just what a name XERVON has made for itself as one of the leading European scaffolding businesses. Both projects involve extremely complex requirements, whether it has to do with weather protection or special anchorage solutions. In fact, we are well-known for delivering specialty scaffolding solutions in all of the countries we operate in. Which was one of the reasons why we invested in our scaffolding business in the German town of Eisenhüttenstadt. With both the workforce and workload having expanded over the last few years, we decided to invest in our employees, in our customers and in the region as a whole.

Experts for the most complex of tasks

XERVON Austria’s scaffolding experts came to the rescue recently drawing up a bespoke solution to erect a scaffold around one of the turrets of the Votive Church in Vienna – saving the church authorities a large sum of money and, once again, demonstrating their outstanding technical expertise.

Keeping the restoration specialists safe

Over the last twenty years, the scaffolding specialists working at XERVON Austria have often been called on to erect scaffolds around different sections of the Votive Church. Their client, the St. Josef’s Foundation of the Archdiocese of Vienna (responsible for historic religious buildings), is one of the company’s key customers. Consecrated in 1879 following 23 years of building work, there is always some part of the church that needs renovating. The Votive Church is considered to be one of the world’s most important neo-Gothic religious buildings. The decision had been made to build this church as a votive in gratitude for the sparing of Emperor Franz Joseph 1 after he survived a failed assassination attempt on 18 February 1853.

An extensive list of restoration work has been planned for the church’s façade, roof, roof truss and windows. Work is currently being carried out on the so-called ridge turret – a 20-metre octagonal tower built 42 metres above the ground on the ridge of the roof at the point where the nave and transepts meet. With a diameter of 4.5 metres at its base, this very pointed turret rapidly becomes much narrower as it rises upwards. It is made of a steel skeleton frame covered in metal sheets. A number of different experts – tinsmiths, metal workers and metal restoration specialists – are now in the process of restoring this structure from their safe work platform on the scaffolding erected high up in the air.

Light, safe and cost effective

  • Engineer Harald Sauerwein, XERVON Austria’s site manager responsible for work platforms and scaffolding, believed that the biggest challenge of this particular project was designing and planning a cost-effective base which the scaffolding could rest on: “There were a number of difficulties to be overcome here. On the one hand, the slate roofs surrounding the turret had themselves just been restored and so it was essential that they were not affected by the scaffolding in any way. Having said that, they are all so steep that they couldn’t have provided a stable base anyway.” The Archdiocese’s planning office had been resigned to the fact that they were going to have to pay for a steel base structure to be built – something that would not only have been very time consuming to set up but also very expensive.

    Within no time at all however, XERVON’s specialists had come up with an alternative that was considerably less expensive: working closely with the structural engineers at the planning office, they developed a concept that involved scaffold lattice beams being placed through the turret openings. These were used as the base for the scaffold, which was then erected around the tower and consists almost exclusively of lightweight aluminium material. The scaffold structure has been designed to bear a weight of 2 kN/m² – more was not possible as this was the maximum load that the church’s roof truss could bear.

Transporting the materials was a complex process

  • Logistics also played a vital role in this restoration project as the church is situated right in the centre of the city: “It was clear from the start that we would need to have a mobile crane on site whilst the scaffolding was being erected, so that the scaffolding material could gradually be passed up as it was needed. The ridge turret’s exposed position and the lack of storage space on the scaffolding meant we had no other choice,” said Harald Sauerwein explaining the relatively time-consuming option used to get the material to the roof. The scaffolding material will soon have to be removed in exactly the same way as the restoration work is expected to have been completed within just three months. And then yet another successful step will have been taken to preserve the Votive Church. A successful but small step as the Archdiocese’s planning office is expecting the restoration work on the outside of the church to take around 20 years and cost 32 million euros. There are, therefore, bound to be a number of other opportunities in the future for the XERVON scaffolding experts to demonstrate their expertise.
