Editorial

In the historic palace district of Aachen sewage pipelines needed to be laid using the gallery construction technique. Duktus pipes were used for this in special lengths of 3 m

Dear readers of inform!

“Vienna is different”. The Austrian Federal capital gave itself this slogan in the nineties. It could in all good faith also be applied to us: Duktus is differ-ent. And from now on TRM in the Tyrol will also be different again!

Since the middle of the last decade, the Duktus Group had gone its own quite specific way. Dissolved out of the former Buderus business and bed-ded down in medium-sized structures, since then it has seen itself as a leading applications and technology oriented company in the water man-agement industry. With its competence and client proximity, Duktus would like to be an excellent problem solver with whom it pays to collaborate. This also applies to TRM, our former subsidiary in Tyrol, which is dedicated to the same aims and which since the middle of 2013, due to the commit-ment of Max Kloger, is standing entirely on its own feet (see also our inter-view on page 17).

Bound by ties of friendship the two companies continue to cooperate close-ly together. Therefore in this issue of inform you will also continue to find contributions from all areas of the business – for example from Austria and Germany and also many countries in which TRM and the Duktus company are working.

In our opinion any article which highlights the particular skills of Duktus and TRM is worthy of particular attention: read our report about a fascinating construction site in Aachen. Here it was thanks to the flexibility of Duktus that 3 m pipes were able to be successfully laid using the gallery construc-tion process (pages 4/5). In Berlin, too, Duktus had the answer – once again with a shortened pipe length a challenging laying project was achieved using the auxiliary tube technique (page 6).

A virtually gigantic project with ductile driven piles was carried out by TRM in South Africa. “KaXu Solar One” is the biggest piling project in the history of TRM and it means that further orders of this kind are to be expected from the land of the Cape of Good Hope (see pages 8/9). We have paid tribute to the success of TRM with the title of the current inform.

To find out how outstandingly suitable the ductile iron pipe system is for fire-fighting pipelines, please read the reports on pages 11 and 13. With both projects it was internationally renowned companies which kept their fire-fighting systems safe by using ductile iron pipes: BASF in Ludwigshafen and the Danish toy manufacturer LEGO at Nyíregyháza in Hungary.We are also proud of the use of our pipes in a spectacular pipe-laying saga

For the foundations of the parabolic reflectors of the KaXu Solar One solar power station in South Africa, TRM supplied more than 100,000 m of ductile driven piles

LAYING 3 M IRON PIPES IN THE HISTORIC SURROUNDINGS OF THE PALACE OF AACHEN

It was thanks to the great flexibility of Duktus that the contract for this fascinating construction pro-ject came into being.Aachen is getting ready for Charlemagne Year in 2014 and this also includes sorting things out underground, which – in terms of sewage pipe-lines – also has historical dimensions, namely the more than 100 year old system of concrete pipes with egg-shaped profiles. Complete reno-vation was unavoidable.In the inner-city area around the cathedral, ar-chaeologists are busy with extensive excava-tions. Aachen, formerly the location of the fa-vourite palace of Charlemagne, who left count-less traces behind him here, is committed to its history and therefore places great store on ar-chaeological work, which takes priority in all building projects.And this was the case when Stadtwerke Aachen AG (STAWAG) was planning the renewal and re-construction of the water supply and sewage pipelines in the area of the palace and commis-sioned AGEVA engineering consultants with the project.

Pipe laying using the gallery construction method It was clear that there was no question of us-ing cut-and-cover or conventional trenchless lay-ing of the sewage pipes, mainly in order to avoid delays in the construction schedule because of the priority given to archaeological work. STA-WAG therefore decided that the entire renovation of the 352 m long sewage line should be carried out by means of gallery construction. The gal-leries for laying the pipes were to be as deep as possible so that they run underneath the archae-ological monuments. As the gallery diameters were tight, it was not possible to get iron pipes in the normal length of 6 m into the gunned con-crete starting pits. Therefore the planning envis-aged laying 3 m long pipes exclusively. The gal-

leries – running from 4 starting pits – were driv-en in a star shape and prepared for laying the pipes. PVC pipes were brought in for interim supply until the pipeline in ductile iron pipes was commissioned. Duktus scored in terms of flexibility “The fact that we got this contract was down to 2 reasons“, said Jürgen Schütten, who was pre-sent during the project as Duktus Sales Manag-er. “As the sole manufacturer, Duktus was in a position to make the required pipe lengths of 3 m available without delay. Our competitors were not able to do this within the timeframe speci-fied. Because of the flexibility of production at Wetzlar we clearly had our noses out in front. And the use of ductile iron pipes was a condition set down in the client’s security specifications. Here the ductile iron pipe system with BLS®/VRS®-T joints met the high requirements stipu-lated because Duktus pipes guarantee tight-ness and hence security underground for many decades. As the galleries, which are located at a depth of 4 to 5 m, will be completely sealed once pipe-laying is completed, and therefore in-accessible, the security and longevity of the pipe material was of the utmost importance for the cli-ent. In addition, Duktus pipes were convincing because of their metallic wall properties. They are stable in terms of position and require little support.”

Work underground The laying of the total of 107 DN 300 iron pipes was a bit of an adventure. Georgios Moutrou-pidis from Duktus Applications Technology de-scribed it: “This type of pipe installation was something new for us and it set us some big challenges, as we had to work underground like miners and deal with all the marginal issues such as dampness, stale air and lack of space.” Once the pipes had been threaded into the start-ing pit, they were carried to the installation site on wagons, as they do in mines, and then in-stalled in the crown of the gallery. The Himmel und Hennig company was re-sponsible for the laying and gallery construc-tion work. Site manager Peter Hennig and Frank Karbe, in charge of shaft construction, offered

words of praise for the perfect collaboration: “We were extremely well coordinated in every phase of this demanding construction project and the support which was given to us by Duktus Appli-cations Technology has contributed to our being able to record this project as a joint success.” It is not only the City of Aachen which is happy with the positive result, laying will be completed in December 2013, as it will no longer have to

AACHEN AND CHARLEMAGNE YEAR 2014

On 28 January 814 Charlemagne died in his palace in Aachen. On the same day the former King of the Franks and Lombards and Emperor of the Holy Roman Empire was entombed in the Palatine Chapel, the octagon of the present cathedral. 1200 years later his life and works stand at the centre point of 3 special exhibitions in Aachen under the title “KARL DER GROSSE. Macht Kunst Schätze” [CHARLEMAGNE. Power, Art, Treasure]. These will be held in Charlemagne 2014 at selected locations of Aachen Palace. Since 794 Charlemagne had stayed in Aachen almost without interruption. The palace was extended into a monumental edi-fice under his auspices. Totally in contrast to the idea of travelling kingship which was typical for the time, political power was con-centrated in a single place as a result. In addition this location was home to a sophisticated, multi-ethnic court society, charac-terised by the presence of scholars from all parts of the Caro-lingian Empire. After Rome, Charlemagne’s favourite palace at Aachen was the political, cultural and religious centre of Europe. At the time of Charlemagne’s death, the Frankish kingdom had undergone enormous expansion. It extended from the Elbe in the east to the Pyrenees in the west, from the North Sea coast to the middle of Italy and it was in diplomatic exchange with Byzan-tium and the Islamic world. In the generation of Charlemagne’s grandsons the realm became fragmented.

The trilogy of exhibitions will show the historical and current di-mensions of these events.Dates: 20 June to 21 Sept. 2014

be concerned about secure wastewater disposal in the vicinity of the palace in future. It has also made Duktus Sales Manager Silke Hackl happy: “We managed to switch our production process over to the shortened pipe lengths at short no-tice and, with our works team, guarantee com-pletion of the project to deadline. This marks us out as efficient pipe suppliers and consultation partners.”

Lifting the short pipe into the pit

Duktus had the answer!BERLIN: BLS®/VRS®-T-ZMU-PLUS SHORT PIPES LAID USING THE AUXILIARY TUBE TECHNIQUE

New route for pipeline

Beneath the busy Mariendorfer Damm intersec-tion in Berlin, directional pipe jacking operations were necessary in order to lay a DN 200 drinking water pipeline.The problem was firstly the small amount of space available for the machine and assembly pits and secondly the spatial restrictions involved in routing the pipe over an underground railway line and under two sewage pressure pipelines, not to mention avoiding damage to the numerous utilities also present. There were no alternative lo-cations available for the excavations.The right solution was quickly found with the auxiliary tube technique. Berliner Wasserbe-triebe, the client, did not want to compromise on this project either in terms of its standard – duc-tile iron pipe – or with the cement mortar coat-ing and the BLS®/VRS®-T joint technique. How-ever, because of the tight space available, it was impossible to use standard 6 m pipe lengths. So the planning engineers contacted Duktus and asked for the possibility of producing short pipes to be looked into. This was no problem for the application technology and production depart-

ment in Wetzlar, so nothing stood in the way of the contract for “ZMU-Plus short pipes” being placed. “At Duktus we are not just suppliers of pipes, we are also problem solvers with a high degree of skill in producing tailor-made products to specif-ic client requirements. It was important that the ZMU-Plus coating should be absolutely dimen-sionally accurate because any irregularities could result in cavities producing a subsidence haz-ard“, commented Sales Manager Lutz Rau on the fast and efficient processing of the enquiry.With the auxiliary tube technique, a section is bored out underground with an auger drill pipe. During the boring process, in order to stabilise the small tunnel, a steel tube is pushed through at the same time so that no cavities can be pro-duced on the outside. Once the steel tubes have reached the target pit, a traction head on

the drilling string is used to pull the steel auxilia-ry tube back in the direction of the machine pit. The BLS®/VRS®-T pipes are coupled to the trac-tion head and pulled through. Stephan Hobohm from Duktus application technology was on site to give advice to the contractors during the in-stallation of the 24 m long pipeline. “The use of 3 m short pipes which could be fitted into the nar-row excavation pit without problem and the easy-to-assemble joints meant that fast progress was guaranteed. The project was successfully com-pleted in September 2013.”

SCHWARZBACHTAL WASTE WATER AUTHORITY USES THE BENEFITS OF DUKTUS ZMU IRON PIPES

Sewer systems do not need to be merely good, they must be perfect, especially when they run through drinking water protection areas.In order to keep to these high requirements for a sewer and to safeguard the groundwater on a sustainable basis, the Schwarzbachtal munici-pal waste water authority in Neckarbischofsheim, Baden-Württemberg, has invested heavily in re-placing an insecure section of its sewage system with a new pipeline in DN 800 and DN 1000 duc-tile iron pipes from Duktus. The measures were planned by the Werner Martin civil engineering and environmental protection office from Reich-

artshausen. The work on the 505 m long pipe-line was tackled in the period between Septem-ber 2012 and June 2013 and went smoothly de-spite adverse weather conditions in some cases. The external protection selected was Duktus ce-ment mortar coating which offered the advantage that the available excavation material could be used directly for encasing the pipes, serving as mineral encapsulation for additional groundwa-ter protection while also contributing to appreci-able cost savings. After successful tightness test-ing the pipeline went into operation in July 2013 as planned.

The greatest part of the new sewage pipeline commissioned by the Schwarzbachtal municipal waste water authority was laid using the cut-and-cover technique with sloping trench walls (left) and approx. 95 m used trenches with walls reinforced with shoring panels and sheet piling (right)

For the sake of nature conservation: pipe laying at the coldest time of the year RENOVATION OF DRINKING WATER PIPELINES IN NÖRDLINGEN

Winter construction work in underground engineer-ing is quite a rare thing. However when it comes to countryside interests and the protection of animals and other species, engineers are happy to make an exception. In order not to disturb the numerous meadow-breeding birds such as lapwings, snipe, meadow pipits and the Montagu’s harrier during the breeding season, the approx. 16 km long water pipeline was laid in the autumn and winter months, reports Josef Hiltner, Technical Operations Manager of Bayerische Rieswasserversorgung (BRW).To come straight to the point: even temperatures in the minus range make no difference to temper-ature-resistant ductile iron pipes. And that was one of the reasons why the BRW in Nördlingen opted for the robust ductile iron pipe system from Duktus. The BRW supplies around 132,000 residents in the northern part of the Schwaben administrative dis-trict. About 6.7 million cubic metres of drinking wa-

ter is delivered to 34 towns and communities each year. In order to guarantee the supply, it operates 3 water treatment installations, 22 pumping stations and 25 elevated tanks. The piping network needed to distribute the water is about 1,300 km long.The so-called middle string laid in 1962 – one of the three main arteries in the Nördlinger Ries – now had to be renewed and its capacity upgrad-ed. The section in question was located – as men-tioned above – in an area where allowance had to be made for endangered bird species. But that was not all. Constraints imposed by the Bavarian office for the preservation of historical monuments had to be observed because the route crosses various prehistoric and early settlements and a battlefield from the Thirty Years’ War. Together with Eckmeier and Geyer consulting engineers, the BRW decided on Duktus pipes with cement mortar coating, not least because the construction work had to be lim-

ited to just a few areas because of the archaeologi-cal digs. As regards compaction and increased cor-rosion protection in the heavy and sometimes ag-gressive soil, resistant ZMU iron pipe was essential for the entire 15.6 km line. Work commenced in September 2012. The Jo-sef Pfaffinger company from Passau was commis-sioned for laying the pipes. They managed to lay the whole DN 400 pipeline in around 6 months.Site manager Jürgen Geyer says: “The logistics went extremely well. At times Pfaffinger was work-ing with 3 gangs and was able to lay up to 500 m of pipeline a day. While the middle string was being laid, 9 local networks in the Donau-Ries district were also connected by means of distribution shafts. Aeration and ventilation shafts as well as flushing chambers were installed at the high and low points. Duktus Sales Manager Wilhelm Faulstich was able to give a positive report after the commissioning of the new drinking water pipeline in April 2013: “Con-sidering the difficult conditions which working in winter naturally involves, completing the installation this quickly was something special and, not least, again shows that Duktus piping systems with their ease in the laying of the pipes, work well and with-out compromise even under harsh conditions.

The so-called “middle string” – one of the 3 main drinking water lines in the Nördlinger Ries – was dimensioned to DN 400 with Duktus ZMU pipes

The Montagu’s harrier, a protected species – it was because of this raptor, among other things, that the construction work was carried out at the coldest time of year

The biggest piling project in the history of TRM

CONSIDERABLY MORE THAN 100,000 M OF DUCTILE PILING REQUIRED FOR CSP KAXU SOLAR ONE IN SOUTH AFRICA

inform reported on the development of the pile business in South Africa in the last issue. Just how positively this success story has continued for the TRM pile system in the country of the Cape of Good Hope can be seen from the per-formance of an absolutely gigantic project in the South African Northern Cape region on the bor-der with Namibia. Here, at the edge of the Kala-hari Desert, a so-called CSP power plant – KaXu Solar One – is being constructed which, with an output of 100 MW, will provide the energy supply for the cities of Johannesburg and Cape Town.

The background ABENGOA, a multinational business based in Spain which has entered into a partnership with the state-owned Industrial Development Corpora-tion (IDC), will operate the KaXu power station for the next 25 years. ABENGOA has entrusted the construction of the power station to its subsidiary company ABEINSA EPC, which has now been working in the vicinity of Upington since the be-ginning of 2013. The South African partner of TRM, the Geopile company, has been commis-sioned by ABEINSA to produce 52,800 piling points for stabilising the parabolic reflectors of the power station.

Pile foundation work began in April 2013Since April 2013, 4 sets of equipment have been in use, achieving an average performance of 300 piles a day. The lengths of the piles vary widely because the construction site extends over an area of 3.5 x 1.5 km. The final volume will not be determined until December 2013. Current pro-jections suggest approximately 103,000 m. Thus it is already established that KaXu Solar One is

Tensile tests on driven piles

Work on the pile foundations for the KaXu Solar One power station began in April 2013. With an expected volume of 103,000 m of driven piles, this is the biggest piling project to date in the history of TRM


the largest project carried out to date with ductile driven piles from TRM. Extensive tests were suc-cessfully conducted in advance. Geopile provid-ed evidence of load bearing capacity on around 10 test piles which were selected on a random basis. With this project, for the first time it was the “pulling” load case which was decisive because the parabolic reflectors, which are set up exactly in the north-south direction, have a low own weight but they must also keep their position even at wind speeds of 140 km/h. Only at wind speeds of more than 140 km/h do the enormous surfaces move into a secure position. Since these high wind speeds are no rare thing in Northern Cape, the parabolic reflectors in the east and west area are protected with 5 m high wind breaks. This will reduce the wind speed and break up wind flow. In the north-south area, where no wind breaks can be erected, earth mounds need to be raised over a length of 3.5 km with a height of up to 10 m. These will also help to break up the wind currents so as to pre-vent the lifting force (suction effect) such as oc-curs with an aircraft wing.

The challenge “Managing tolerances” is what the challenge is about. The production of the piles at KaXu Solar One will be monitored by total stations which al-low a precision level of +/- 4 cm to be achieved. The actual connecting link here is a DN 27 mm bolt which has to be concreted in by Geopile with a precision of +/- 3 mm in position and +/- 20 mm in height. Such precision work was called for because, being at the heart of the solar ther-

mal energy plant, the parabolic reflectors must be installed at precise positions and heights in or-der to guarantee 100 percent effectiveness. A deviation of just 1 degree reduces the perfor-mance by 5 percent.Production of the piles went according to plan and within the required time frame so that – as Erich Steinlechner, Head of Pile Systems Sales,

The parabolic reflectors of KaXu Solar One will be protected in the east and west area of the plant with wind-breaks which will help reduce high wind speeds and break up wind flows. The TRM driven piles mean that the reflectors can be erected at precisely the correct position and height despite their low own weight

stresses – the requirements in terms of accuracy and deadlines could be entirely managed. “In this project of the century we are proud of the fact that our capabilities have been convincingly demonstrated and that TRM driven piles have been shown in the right light, namely as a system which also functions perfectly with major chal-lenges and innovative projects.”

CSP SOLAR POWER

CSP plant is used in the Earth’s sun belt because these desert-like areas have the necessary high levels of solar radiation. With CSP (Concentrated Solar Power or solar thermal power) re-flectors are used to focus the sun’s rays by a factor of 90 onto a heat transfer medium (usual-ly thermal oil or even water) contained in the receiver tube. The energy generated can be used for the production of steam, heat, cold or electricity. If a CSP plant produces electricity with the help of a steam turbine connected to it, then we refer to it as a solar thermal power station. CSP offers an endless potential for thermal energy generated from the sun. The energy from CSP stations can easily be stored in the form of heat and then released again later for con-sumption.

South Africa has decided to become increasingly active in the area of solar energy in order to make its energy supply more independent from fossil fuels – especially coal. Coal deposits are rather limited in South Africa.

3 crucial factors play a role in solar thermal power stations: sun, because water has to be turned into steam. Sufficient volumes of water and a substation, in order to bring the volumes produced to the end clients.

In South Africa the ideal conditions are present in order to operate this type of power station eco-nomically. In the Northern Cape region on the border with Namibia the sun shines on 320 days of the year and the Orange River which, at 2,160 km long, is the greatest river in the country, supplies sufficient volumes of water.With the KaXu Solar One project, the country is making a start in the matter of generating ener-gy for tomorrow. A further 100 power stations are planned, not only CSP but also traditional pho-tovoltaic plant.

What does this mean for TRM?We asked Erich Steinlechner, Head of Pile Systems Sales, about this. “Good prospects, natural-ly! Energy policy in South Africa is backing solar and we as pile producers will be able to conti-nue to secure a stable position in the South African market after the successful completion of the KaXu project together with our partner Geopile.”

CHALLENGING CONDITIONS FOR LAYING BLS® DRINKING WATER PIPES IN THE ASTURIAN MOUNTAINS

Sifón del Alba – pipe laying by helicopter

For the most part, the Spanish industrial city and seaport of Gijón with around 230,000 inhabitants draws its drinking water from the Los Arrudos headwaters about 60 km away. Playing a crucial part in guaranteeing that the supply to the Asturi-an metropolis is secure in the future (again) was the ductile iron pipe system from Duktus and the consulting competence of Construtec, the Span-ish sales partner of Duktus.The so-called “Sifón del Alba“ project is the excit-ing story of pipe-laying at its most difficult, in which planners, consultants, logistics people and laying teams had to perform their very best work. Because of its uniqueness, the project was a topic of great public interest and the local press did not tire of reporting on the Sifón del Alba.A steel pipeline which had transported drinking water from Los Arrudos to Gijón since 1940 –

around 6 million cubic metres a year – had been attracting negative headlines over recent years because of corrosion damage and dramatic pipe bursts. One pipe burst which caused a landslide prompted the local supply company Empresa Municipal de Aguas Gijón (EMA) to get the con-struction of a new section underway with an in-vestment of several million euros. Construtec managing director Francisco Dominguez explains the problems of the situation: “The task of renew-ing this old pipeline, which was almost completely non-functional in places, confronted the planners with a number of challenges. They started with the most difficult section of the pipeline. The con-ditions of the terrain which had to be tackled here made it necessary to use a siphon system – the course went from the heights into the valley and then uphill again. The pipeline is under high pres-sure at both ends. Then the conditions of laying had to be taken into account – steep, almost im-passable sections and the crossing of the bio-sphere reserve at the Parque National de Redes. We at Construtec, as application technology con-sultants, were able to get together with Duktus at an early stage and give the EMA as well as the planning office Tecnia Ingenieros comprehensive support. It quickly became apparent that, for the

planned DN 400 pipeline with average gradients of 58 percent, a maximum gradient of 128 per-cent and pressures of up to 54 bars, only the BLS®/VRS®-T pipe system from Duktus was worth considering.” Construction engineer Ruben Egui-luz adds: “No other pipe system would have made sense here. BLS®/VRS®-T pipes enable pipelines of this diameter and for high pressures up to 50 bars to be laid in trenches without thrust blocks. Because the route runs through the bio-sphere reserve, the risk of forest fires due to weld-ing work also had to be excluded. We could not have guaranteed this if we had used steel pipes which need welding. In addition, value was placed on fast progress of work because the lay-ing needed to be completed during the short summer months.”The ambitious Sifón del Alba project was launched in July 2013. 1,884 m of ductile drink-ing water pipes with cement mortar coating based on blast furnace cement and a zinc-bitu-men external coating were delivered. 3 weeks of strenuous work began for the laying teams from CESME and New Construction S.L. Manuel Fernández Martínez, managing director of New Construction, describes it: “Our teams on site worked like experienced mountaineers. Almost

vertical mountain faces had to be conquered in order to lay the Duktus pipes. We left nothing to chance with this. The entire section of the pipe-line was equipped with a lifeline, meaning that all workers were secured with ropes like miners.”The majority of the pipes were flown in by helicop-ter. A company from Catalonia was responsible for this and the helicopter pilots are specially trained for transport flights of this kind. On the return trip in each case the helicopters took the old rusted steel pipes back with them for disposal. Walking excavators were used on steep parts of the terrain and it is thanks to the professional col-laboration of all involved that this pipeline could actually be laid within 3 weeks and was ready for pressure testing. Steffen Ertelt, head of Duktus applications technology, instructed the employees of CESME and New Construction in the laying of BLS®/VRS®-T pipes. For him there is no doubt that the Sifón del Alba will function perfectly.

Since 1976 the BASF northern inland port in Lud-wigshafen has been a trans-shipment point for flammable liquids such as naphtha, methanol and compressed liquefied gases. Each day the roughly 140,000 square metre dock is the desti-nation of 7 ships on average. It is obvious that the safety precautions in terms of fire protection are taken very seriously here. BASF employees moni-tor the handling of goods from the port control centre with movable cameras around the clock. In case of fire, fire-fighting operations are activated using foam and water cannons. Since the com-missioning of the port these foam and water can-nons have been supplied with water via under-ground steel pipelines. Leaks had been appear-ing over recent times so a replacement of the pipeline now became necessary. Because of the requirements that needed to be met (guarantee-ing security of supply and keeping access routes free for works traffic and the emergency services) it became clear relatively quickly that the renewal of the main service pipelines should be done with ductile iron pipes using the bursting process. Oth-er renovation possibilities were excluded for tech-nical reasons. For the 1.5 km long fire-extinguishing pipeline, Duktus drinking water pipes with BLS®/VRS®-T joints and ZMU coating in nominal widths DN 300, DN 400 and DN 500 were used.Once the pits had been excavated, the laying work began in May 2012. It then turned out that the soil on site could only be forced out with diffi-culty and sometimes not at all. This quickly led to the tractive forces being increased and naturally also a shortening of the drive lengths. The limited ability of the soil to be displaced meant that the steel pipe cut open was forced from the soil against the sockets of the iron pipes, thereby in-creasing friction and traction considerably. An additional increase in tractive force was pro-duced by “folding” the steel pipe. This phenome-non acts directly at the expansion stage, where

the upsizing head pushes the old pipe before it and it folds up like a concertina. The addition of these individual components quickly led to the permissible tractive force – or at least that achiev-able by machine technology – to be produced. On average it was necessary to halve the installa-tion lengths envisaged at the planning stage, thereby doubling the number of installation pits. In the end, lengths of up to 80 m at a time were achieved. Because the machines had to be re-equipped for each new length (they run for ap-proximately half a working day) the time required for the work increased accordingly. Apart from that, the construction work proceeded largely without problem. But is showed how deci-sive the influence of the condition of the soil is on outcome and costs. The fire main went into oper-ation in August 2013.

MUNICIPALITIES OF PINZGAU DEVELOP THEIR WATER SUPPLY SYSTEM WITH DUCTILE IRON PIPES

Hand in hand the matter of drinking water

Happy with the success of the community project: (from left) Anton Rattensperger (engineer and MD of the Unterpinzgau Conservation Asso-ciation), Hermann Kaufmann (engineer and mayor of Zell am See), Herbert Reisinger (mayor of Bruck), Leonhard Madreiter (mayor of Fusch)

The two Salzburg municipalities of Zell am See and Bruck an der Glocknerstraße were recording up to 15 burst pipes a year within their own drinking water supply system. These circumstances induced the municipalities to renew the Wölflernquelle water-works, the source for which lies in the neighbouring municipality of Fusch. The old PVC pipelines were removed and replaced with high quality cast iron pipes from TRM. Around 4 million euros were invest-ed in this project, which was completed in autumn 2012.Today the two municipalities are operating extended ring mains. In Bruck around 1,115 households and businesses are being supplied with drinking and service water from this. In addition the tourist capaci-ty accommodating 2,000 guests is covered. 90 per-cent of the water comes from the Wölfler source – and Bruck an der Glocknerstraße draws around 240,000 cubic metres a year from this source. The maximum daily demand in Bruck is currently around 14 l/s. In the tourist hotspot of Zell am See with around 9,500 residents and 8,800 visitors, demand is reckoned to be 5 times higher. “The current maximum water consumption in Zell is 76 l/s. Previously this requirement was covered by a system of elevated tanks, drinking water pumping

stations, control stations and flow metering equip-ment. The water comes from the Waxeck and Bre-itenbach sources in Schmittental, the Finsterkendl source in Thumersbach, the Wölfler source in Fuschertal and the Prielau groundwater waterworks”, explains Anton Rattensperger, Managing Director of the Unterpinzgau Conservation Association. According to a water consensus, the Wölfler source in the neighbouring municipality of Fusch is used jointly to a level of 100 l/s by the two communities of Zell am See and Bruck. The source is routed via a gulley directly into a collecting well. From here the water is routed through an approximately 10 km long piping system to the Bruckerberg reservoir. This connects it to the separate supply pipelines for the communities of Zell and Bruck. “The overriding problem over recent years has been that with the existing DN 250 transport pipelines only a maximum of 80 l/s could be conveyed to the Bruckerberg wa-ter treatment plant instead of the planned 100 l/s. The diameter of the pipe was simply too small. Add-ed to that, there were frequent technical defects”, says Rattensperger, going on to explain the reasons for the defective condition of the existing piping sys-tem: “As in very many other municipalities, what we had here was PVC pipes which, after 40 years’ ser-vice, were no longer in any kind of good condition”. Because, in the future, the required flow rate of 100 l/s would not be able to be supplied from the Wölfler source with the existing system – and once again to be able to provide secure conditions in the pressure pipeline system – the two Pinzgau communities decided to make a joint effort to renew the complete Wölflernquelle water supply system. In the end this was not limited to simply replacing the pipeline but it also included the expansion of the reservoir at Bruckerberg. In their deliberations the question which the communities paid the greatest attention to

was what piping material should be used for the new pipeline. “The three decisive criteria considered for the choice of material were: operational reliability, service life and cost-effectiveness. And so the only possibility for us was ductile iron pipes. Therefore we commissioned the TRM company to supply the pipes”, explains Rattensperger. DN 300 ductile drinking water pipes were supplied which would guarantee that the entire volume of drinking water allocated of 100 l/s could be reliably conveyed from the Wölflernquelle and which would last for many decades. TRM pipes guarantee tight-ness at high internal pressures and also at negative pressures, they can withstand high stress levels and are not affected by tree roots. In practical terms, the ease of laying the pipes was applauded by the ex-perienced installation team. No special bedding material was necessary and the BLS®/VRS®-T joints made angling the route of the pipeline possible in a simple way. Another important factor in the choice of pressure-tight piping material was a further as-pect of the renewal project, namely the inclusion of a drinking water power plant between the intake structure and the Bruckerberg reservoir. Meanwhile the two communities are drawing the higher propor-tion of their water from the Wölflernquelle as envis-aged. This is exceedingly important for the munici-pality of Bruck, whose drinking water requirement is almost exclusively covered by this. But even at Zell am See the significance is rated highly: “With the renewal of the Wölflernquelle we now have around a fifth more water available. Considering the rapid development of our commercial and industrial sec-tor, any additional safeguarding of our drinking wa-ter supply is extremely important”, stresses Silvia Lenz, head of the building department for the mu-nicipality of Zell and manager of this successfully accomplished project.

The Pinzgau municipalities of Zell am See and Bruck invested 4 million euros in the improvement of their drinking water supply


Only the best is good enough for LEGO TRM EQUIPS THE LEGO FACTORY IN HUNGARY WITH IRON PIPES FOR THE FIRE-FIGHTING PIPELINES

LEGO is everywhere. Children all over the world are inspired by the building bricks which can be fitted together so easily and promote and demand creativity. The reason why the Danish toy manufac-turer, founded in 1932, with more than 12,000 em-ployees across the world and the motto “Det bed-ste er ikke for godt“, which roughly translates as “Only the best is good enough” is now making its appearance in inform has nothing to do with the fact that its motto also applies to the products of TRM – it is because LEGO is building a new facto-ry in the Hungarian city of Nyíregyháza for the pro-duction of the “Duplo range”. The toy giant has invested around 200 million euros in this factory.

For fire protection, a high quality fire-fighting sys-tem was produced with water pipelines in ductile iron pipes from TRM.

In Nyíregyháza, which is not far from the borders with Slovakia, Romania and Ukraine in the north-east of Hungary, LEGO has already had a pres-ence since 2008 and has established around 20 percent of its worldwide capacities there in a rent-ed production location. Some 8.9 billion LEGO bricks a year are produced here, of which 650 mil-lion are the Duplo type. Because the rental agree-ment runs out in 2015, a year and a half ago LEGO announced that it was going to build a new factory.

With a production area of 122,000 square metres, the new factory is 3 times bigger than the previous one and will become one of the largest Lego pro-duction locations in the world. For Nyíregyháza with around 120,000 inhabitants this huge investment in the East Hungarian region is a stroke of luck because in the long run about 250 new jobs will be created and production ca-pacities are due to double as compared with cur-rent volumes.The excavation work for the new production centre, where 768 injection moulding units will later be installed, began in February 2013.LEGO attaches great importance on aspects such as sustainability and environmental friendliness, so renewable resources should also be used in the energy supply for the factory sites. For fire protection an efficient fire extinguishing system will be used which has been planned ac-cording to the most modern considerations. In the choice of pipes for the extinguishing pipelines, TRM and the local sales partner for Hungary PURECO were able to convince the owner, Lego, and the general contractor, Colas-Alterra, of the quality and advantages of ductile iron pipes with the high quality Purlonglife coating and BLS®/VRS®-T joints. “No other pipe material was more suitable because extinguishing water pipelines in ductile iron pipes are not combustible and they offer high safety margins against stresses. Added to this is the quick and simple assembly of TRM pipes, meaning that the construction company was able to install more than 3 km of DN 250-300 pipes in the shortest time”, said István Öllos, Director of the Public Works Division of PURECO, and Roland Kröpfl, TRM Sales Engineer Export, added: “We were able to put the package of consultancy, ser-vice and product together successfully for the end client. It is a joy and always a thrilling challenge when we can score points even in a communal project which is somewhat off the beaten track.”

The construction work for the new LEGO production works in the Hungarian town of Nyíregyháza has been in full progress since February 2013

More water after renovation

The new Hagenbucher skills centre in Eglisau

“All good things come in 3s”. With the move to Eglisau, TMH Hagenbucher, sales partner of Duk-tus in Switzerland, acquires its 3rd warehouse location in the last 25 years. This is a reflection of the constant further development of the Hagen-bucher Group from its small beginnings to a lead-ing supplier of piping systems for water supply and waste water treatment.The buildings of the former mineral spring at Egli-sau are the new storage headquarters, on the one hand having the necessary space for merg-ing the previous locations of Embrach, Lufingen and Schaffhausen and on the other hand being a place where sufficient reserves are available for future development. It offers a bright and effective working space for logistics and production work-ers.“We are convinced that by concentrating in one location we can offer our clients an even better service. The space provided by the new location will allow us to increase the number of cement mortar coated pipes in store considerably and also to keep other Duktus pipe products as well. At the end of January 2013 the first stage was embarked upon with the Embrach warehouse

move. After about 3 weeks and umpteen lorry trips, everything was at the new location. The ac-quisition of new warehouse premises means that we can further optimise the storage of shaped parts and fittings. Also our civil engineering busi-ness Hagenbucher Grabenlos (TPS) has moved its operations centre from Lufingen to Eglisau”, reported Managing Director Bruno Solenthaler.

THE ALT ST. JOHANN-UNTERWASSER WATER COOPERATIVE BACKS QUALITY

In autumn 2012 the water cooperative of Alt St. Johann-Unterwasser in the Canton of St. Gallen renovated the spring capture of the Burstel and the spring abstraction pipelines. The extensive investment became necessary in order to improve the infrastructure of the drinking water supply for the villages of Unterwasser and Alt St. Johann. As the water cooperative placed great value on qual-ity and cost effectiveness, it was quickly clear to the engineering office Gruner und Wepf AG from Buchs commissioned for the project, that for the laying of this challenging pipeline, ductile iron pipes with cement mortar lining and cement mor-tar external protection were the best choice. Over a length of 1,200 m, the old DN 125 pipelines were replaced by DN 200 cement mortar coated pipes with BLS®/VRS®-T joints. “The larger di-mensioning of the pipes meant that the output of the Burstel source could be increased, so that now a supply of up to 1,500 litres of water a min-ute is possible”, as Matthias Ensinger, construc-

tion engineer at Gruner und Wepf, described the construction project. The steep terrain, the con-fined space and the constant flowing water made it necessary to carry out the laying in stages. In some particularly impassable areas of the route the pipes were flown in by helicopter. In the end the clients were satisfied because the Burstel spring abstraction pipeline with the easily assem-bled BLS®/VRS®-T pipes proved to be a cost ef-

fective solution with the best quality: thanks to the flexible connection technique the number of shaped fittings could be reduced to a minimum and, because of the robust cement mortar coat-ing of the pipes, the excavated material could be used directly for backfilling the trenches using a bucket crusher, meaning that expensive transport off-site and deliveries of concrete aggregate were not necessary.

The cement mortar coating of the pipes allowed the trenches to be backfilled with the excavated material

The spring abstraction pipeline was laid by Tobler Haustechnik + Metallbau from Alt St. Johann

DELIVERIES FOR GAS POWER STA-TIONS IN HILLAH AND KARBALA

Over the last few years Duktus has been able to get itself well placed in Iraq on a number of pro-jects with its BLS®/VRS®-T pipes and scored well in terms of quality and reliability in delivery. The most recent success is the supply for the planned gas power stations in Hillah and Karba-la which are being developed by Infrashore Co, a long-term client of Duktus from Bahrain. For years Iraq has had to struggle with an old and fairly unreliable energy supply. Power cuts are a daily event and in many parts of the country they have contributed to dissatisfaction among the people and even led to demonstrations. In order to improve this situation, the Iraqi Ministry for Electricity has made around 170 million dollars available for building gas power stations in the towns of Hillah and Karbala which lie to the south of Baghdad. After a planned construction period of 18 months the power stations will sup-ply 80,000 households with power. Duktus is delivering ductile iron pipes and fittings for these projects. Leon Bauer, Duktus Pipe Systems in Dubai, comments: “In the highly competitive market of Iraq, Duktus has shown over and again that flexibility, reliable delivery and quality all help to achieve follow-up orders. For years now our client Infrashore Co from Bahrain has been relying on ductile iron pipe systems from Duktus and the outstanding performance of Duktus Pipe Systems in Dubai. The current pro-ject involves a total of 7,077 m of BLS®/VRS®-T pipes in DN 150 to DN 300 and approx. 750 fittings of the same diameters which will be re-quired for the construction of the power stations in Hillah and Karbala.” The pipes were shipped via Antwerp to Umm Qasr in Iraq between February 2012 and Sep-tember 2013.

The pipeline is in Krakau’s flood protection area and runs parallel to a flood water dam 3 m away. Therefore it was decided to use the trenchless Horizontal Directional Drilling technique for laying the pipeline

The 1,422 m long new drinking water pipeline in Krakau was laid using the HDD process with Duktus BLS®/VRS®-T pipes (ZMU)

Good experiences pay off DUKTUS MAKES THE RUNNING IN KRAKAU!

The satisfaction of Wykonawca AG System Krakau with the ductile iron pipe system from Duktus for laying a pipeline in Breslau, the so-called “Szybki-Tramwaj” project has paid off. Against strong competition, Duktus once again won an order in Poland – for a 1,422 m long drinking water pipeline in Krakau which was laid using the Horizontal Directional Drilling method.Krakau, with a population of around 780,000 people, is the second largest city in Poland and because of its historical significance and its cur-rent economic power is happy to be described as a capital city on the quiet. As a venue for many future major sports event, it is investing huge sums in the infrastructure, and above all in flood protection and the drinking water supply. This large city on the Vistula has repeatedly had to battle against flood catastrophes which have also jeopardised the drinking water supply.The new pipeline, which consists of Duktus

DN 400 ZMU pipes, should also be looked at in this context. It was laid in the area of Mary-narska street with the purpose of supplying the north-west part of Krakau. It runs alongside the Rudawa river in the flood protection area. The client decided to carry out the laying work us-ing the Horizontal Directional Drilling method be-cause the line runs parallel to a flood water dam just 3 m away. The measures, which were esti-mated for a construction time of 3 months, were completed in summer 2013 – once again to the client’s satisfaction. Adrian Warzecha from Duk-tus sales partner TALIS Polska, who did a great deal to contribute to the successful awarding of the contract, feels sure that the trenchless lay-ing technique will be increasingly used in Poland with its upcoming cities. “Naturally, with BLS® pipes from Duktus as in most cases they are best suited to the HDD process and the other trench-less laying methods.”

Snow pipes for North Germany’s biggest skiing area

WURMBERG IN HARZ EQUIPS ITSELF FOR A FUTURE OF GUARANTEED SNOW

With an investment of more than 8 million euros a contemporary tourism infrastructure has appeared on the highest mountain in Lower Saxony. This is helping Wurmberg and the Harz to move up into the top rank of German winter sports areas.Wurmberg has also been the biggest skiing re-gion in North Germany until now. However, the lack of certainty of snow, sometimes long wait-ing times and terrain which is not very diver-sified in terms of ski sports, were factors which clouded the image of the No. 1 in Lower Saxony.

With the measures planned in the context of the current construction project these problems will be remedied: Wurmberg will have guaran-teed snow, the range of slopes will be consid-erably upgraded and, thanks to a powerful new four-seater chair lift, long waiting times will be a thing of the past. In addition to the chair lift and the efficient snow-making equipment which means that even without a flake of natural snow, within 72 hours skiing can take place on 5.4 km of slopes, the centrepiece of the construc-

tion project is the new “am Osthang” piste. With this, Wurmberg gets a new 1.2 km long, ideal-ly sloped piste, which is just as inviting for fast carving turns as it is for relaxed turns and for skiing and snowboarding enjoyment par excel-lence. In order to put this North German snow security initiative into effect, Wurmberg Ca-ble Railways called in professionals from Aus-tria. The snow-making equipment was planned by the Tyrolean company Klenkhart & Partner Consulting, and the well-known manufacturer of snow-making equipment DemacLenko made sure that the proven BLS®/VRS®-T snow-pipe system was used. “We have already got nu-merous projects up and running together with DemacLenko. TRM as a specialist in snow pipes and a consultant in application technology, to-gether with the snow-making specialist Dema-cLenko, have always been jointly able to focus on their common strengths. And that is the way it went with the Harz flagship project as well”, said Stefan Sterr, head of high pressure systems at TRM. For the snow-making equipment at Wurmberg more than 3 km of ductile iron pipes were delivered. 111 hydrants are supplied by the snow pipes. The water comes from a 5,000 square metre large storage reservoir which has been created at the top of the hill. As from next season skiing fans will be able to have fun 971 m up at Wurmberg bei Braunlage even if there is no natural snow. The laying of the pipes proceeded quickly and without any problem, which also pleased Karl-Wilhelm Römer, the Duktus Sales Manager in charge of this region: “Once again this showed that our BLS®/VRS®-T system is simple and easy to lay. It meets the requirements of modern snow-making systems outstandingly well.”

The winter sports and skiing area of Wurmberg bei Braunlage in the Harz is being crucially developed in the context of the “Wurmberg 2015” concept “. Powerful lift equipment and guaranteed snow – that’s what Wurmberg will be offering as from winter 2013/14. The snow will be provided by 111 snow cannons which are supplied with water by a 3 km long system of ductile iron pipes

At a height of 971 m, Wurmberg offers good climatic conditions for snow-making technology

The proven snow pipe system with BLS®/VRS®-T thrust and tractive restraint makes the laying process problem-free; it was started in summer 2013

“We want to continue taking advantage of synergies”

After 17 years together – first in the Buderus group – and then as from 2010 under the name Duktus – as from 1st January 2013 Duktus Tirol-er Rohrsysteme GmbH is once again an inde-pendent, owner-run company and is called Tirol-er Rohre GmbH with the traditional logo TRM in the green rings.Duktus S.A sold all shares in the 100% subsidi-ary Duktus Tiroler Rohrsysteme GmbH, at Hall in Tirol, to the long-standing Technical Director Max Kloger in the context of a management buy-out. We conducted an interview with Max Kloger who gave us a transparent view of the motivations and future directions.

DUKTUS TIROLER ROHRSYSTEME IS TRM AGAIN –INTERVIEW WITH MAX KLOGER

Herr Kloger, what was your main motivation for this step?

The situation on the European markets has been very difficult over the last years. That did not fail to leave its mark on us as well. Here, at the Hall location, we have always backed niche and spe-cial products. I decided on this step because I am convinced that we can occupy these niches in an even better and more efficient way if we can follow our own path without considering group interests.

So how is the separation from Duktus in Wetzlar proceeding? Could such a step be taken without “atmospheric disturbances”?

Absolutely! The separation went amicably and we shall also try to use our synergies in the best possible way for both sides in the future. Now as ever, we will each supply the other with products which he does not have within his portfolio. In ad-dition we will also continue to work together on research and development.

Do you think that Austria, your home mar-ket, is reacting positively to the name change or has “Duktus” already become ingrained?

One thing is clear – the brand name Duktus has certainly not done us any harm here in Austria and especially in the Tyrol. But we have found that “TRM” is also extremely deeply rooted in our markets and carries great weight. We have had some very positive feedback on the change back to TRM, both from clients and also from the work-force. All this has a lot to do with emotions. We

have noticed that there is a strong identification with the brand here and that the team spirit is expressed very strongly within the company.

What are the challenges which will be fac-ing TRM in the coming years and what tar-gets have you set for yourselves?

As I said before, we will also be collaborating amicably with our former sister company Duktus in the future and using the existing structures to mutual advantage. The central challenge is to achieve growth in order to fully utilise the availa-ble capacities. Obviously we are dependent on economic trends as well as the prices of raw ma-terials and energy, which as always have a major role to play. We are a recycling company and produce our pipes from scrap metal which we buy in. Therefore the price of material supplies is just as important a factor as the cost of energy, whether electricity or natural gas. These prices determine our competitiveness.Our aim is to provide stable employment condi-tions for our staff, who number around 200, and to remain an essential partner in the field of pipe systems and specialist underground engineering, to have an even better presence in niche markets and to introduce new products for new applica-tions. Developing further and looking into new requirements and demands on the market must not be neglected. We will therefore be directing our focus even more on individual client require-ments and offering tailor-made solutions with good price-performance ratios. We are confident that, with our efficient production, we will contin-ue to have our place on the European markets.

Herr Kloger, thank you for talking to us.

As sole owner, Max Kloger heads up the skills of TRM –Tiroler Rohre GmbH – and is certain that the company, with around 200 employees, will continue to play a successful role in the iron pipes business

At an early stage his talent for sales activities in the field was discovered and in the next decades he developed further and further to become an expert in all questions concerning ductile iron pipe. It is thanks to his commitment that almost every-one in the iron pipe industry in the Rhineland region, which from the beginning of his career until his retirement on 31 July 2013 was “his” sales region, is today aware of the advantages of ductile iron pipe systems. Always in a good mood, he displayed great staying power even when it came to working through the night. Elo-quent Harald Oster – who was born in 1948 in Alken on the Mosel – made a name for himself, as our colleague and as a contact for our clients, which is known far beyond the Rhineland region. From his many business relations over the course of the years he has developed friend-ships which will continue to exist even after the end of his professional activities. With countless projects, and sometimes particularly challenging ones, around the Rhine and the Mosel he has

shown that, in addition to his feeling for commer-cial matters, he also has a strong grasp of tech-nical questions. Here at inform we have reported on many construction projects with ductile iron pipes which were completed to the satisfaction of all thanks to his comprehensive consultancy skills. All his colleagues, and especially those from sales, would like to take this opportunity to offer thanks for the time spent with Harald Oster over many constructive and pleasurable hours. We wish him many more happy years in the cir-cle of family and friends. As insiders know, his grandson Luca will make sure that granddad will

not get bored. We will be particularly pleased if in future, at least once a year on the Duktus fam-ily day, we can convince ourselves that his well-deserved retirement is treating him well.Harald Oster‘s successors are his colleagues Heinz-Jörg Weimer, Karl-Wilhelm Römer and Jür-gen Schütten. Since 1st August 2013 Florian Häusler has been responsible for the Mittelhes-sen/Rhineland-North sales area; before that he held an administrative post in house. In numer-ous client visits made together, the old hand Os-ter has given his 25-year-old colleague the best preparation for the new job.

KARL-WILHELM RÖMER LENDS A HAND

During the flood disaster in summer 2013, time and again it was the many voluntary helpers and their tireless efforts who were praised the length and breadth of the country. Everyone was im-pressed by the coherence and perfect organisa-tion of the helpers, both between each other and in interaction with the emergency crews of fire-fighters, the technical relief agencies and the armed forces. One of those who stepped in to offer help where help was needed and combat the flood was Duktus Sales Manager Karl-Wil-helm Römer. Together with his comrades from the Diemelsee fire brigade and the civil protec-tion services for Waldeck-Frankenberg, Römer spent a whole 9 days in the greater Dresden area in Saxony coordinating around 100 rescue teams. Affected by the events, he reported: “Our main task consisted of securing and considera-bly raising an embankment near the Meißen dis-trict of Wildberg over a length of 500 m with sandbags in order to protect the town from flood-

water. Before our arrival, the population and the local emergency services were completely on their own. Together with the emergency services of the district and from the city of Darmstadt and with the support of the armed services, more than 110,000 sandbags were filled and piled up. Our team from Waldeck-Frankenberg worked in shifts – up to 12 hours work, then at least 8 hours rest and sleep. For the last of the emergency services, who drove back to their lodgings in Dresden at about 4.00 in the afternoon, it meant starting again at around midnight.” Römer was overwhelmed by the sympathy and gratitude shown by the population. “We were given cakes, drinks, fruit, sandwiches and rolls and always words of acknowledgement. That was certain to give us all new motivation for our efforts.” On 11 June 2013 it was then a matter for Karl-Wilhelm Römer, exhausted but contented, to embark on his journey home to Sauerland to get to grips with Duktus again.

Such beautiful cars!DIRK WEBER, MAINTENANCE FOREMAN, LOVES TINKERING – HIS HOBBY IS TUNING

His hobby started when he got his driving li-cence. From that point on, Dirk Weber was fasci-nated by cars and turned the tuning of his vehi-cles into a hobby. The thought that, with his ideas and his personal skills in all things to do with “tinkering”, he would ever be really successful had never occurred to Dirk Weber.The tuning fanatic is a maintenance foreman at Duktus. He did his training here as an industrial mechanic and, having been with the company for 25 years, he is practically a Duktus veteran. Maintenance is a pleasure to him (professionally). “This provides the possibility of doing various types of work, we get to move around the entire works and the tasks are challenging. So mainte-nance is a kind of hub in the business and it is never boring“, said the 41-year-old. Dexterity, skill and lots of technical understanding are also im-

portant for his hobby. Added to this is also a cre-ative touch without which a person would not get along with tuning. “As I started playing around with cars together with friends, it was very quickly clear to me that tinkering alone was not my aim, I wanted to make something special of my cars, something unique, not just the engine perfor-mance and chassis but the whole appearance of them.” This is what Dirk Weber has managed to do since then, because his VW Cabrio Eos has meanwhile been featured in numerous specialist journals and has won prizes and trophies. The amount of effort and time that needs to be spent in order to turn a normal car into a star can only be imagined when one looks at the Eos. Dirk Weber has had the complete interior redesigned by a saddler according to his own ideas. Every-thing in leather, in cream and dark red colours

with special appliqué work on the seats. In the press (VW Scene 08/11) the car was described as a 260 HP chocolate bar with a cream filling, after Dirk had given the Eos – at one time Samoa Red – a matt brown film coating. “Variety is a must”, reckons this man from Waldgirmes, who is quite sure that even the chocolate bar is not his last word in matters of pimping. The fact that the princess on four wheels has been lowered to the maximum is total normality for tuning freaks. The chassis has been completely rebuilt. Dirk did this partly himself. Changing the hydraulics meant that the properties of the chassis were able to be altered. At the moment the 4.4 m long Cabrio floats on air instead of on oil and since 2010 the alloy wheels have grown by an inch in size. With this wonder of engineering and beauty it is also possible to drive on a more or less normal road with this adapted ride height, although anyone who has anything to do with tuning knows that this is not the issue at all with show cars. For everyday purposes, Dirk has a so-called bread-and-butter car which he drives to work. Indeed, this Audi is not “completely without” ei-ther: lowered it certainly is, but it manages to run over the tracks in front of the entrance to the Duk-tus works without problem. At the weekends, Dirk, his Eos princess and his friends, who all have the same hobby, go off to show the beauty at exhibitions and fairs. “We are a dedicated group and we mutually support each other in our tinkering and also in generating ideas“, he said and he is delighted to have won so many tro-phies already. What will the future bring? Dirk does not know precisely but it could be that the foil will come off again and the Eos will once more be radiant in Samoa Red. In any case the tuning press will continue to cast an eye in the direction of the Duktus mainte-nance man and report on his ambitions because – no question about it – his ideas are special.

Something completely different!

Lots of people came!

“Something completely different“ was the creative idea for the Duktus Family Day on 24 August 2013 thought up by the organisation team of Pa-tricia Olcay, Jacqueline Bablich, Stefan Pohl and Stefan Brück and it turned out to be a great suc-cess, because around 220 Duktus staff with their kith and kin set out on the 4 km walk and paid tribute to the Duktus motto “health” for the year 2013. They hiked to the Fortuna Mine at Oberbiel, which has a special connection with Duktus be-cause iron ore obtained from here used to be smelted in the former blast furnaces. Today the mine is a visitor centre for the mining industry and a favourite destination in the region.So that the hike would not be a disappointing trudge for the children, the organisers prepared an exciting treasure hunt. The children had to look for letters of the alphabet which – when put in the right order – would finally spell out the solution, telling them that the treasure was in the sandpit. This was well received and the kids were delighted with the treasure chest chock-full of goodies. Everyone enjoyed the day and the

delicious snacks which were waiting for them in the pithead building of the Fortuna mine. At tem-peratures of over 20 degrees C, the ice cream cart ordered as an extra was very popular. Dur-ing the day everyone had the possibility of visit-ing the galleries of the mine or taking a trip on a locomotive.“This family day – away from company premises for the first time – was really great, full of variety, well organised and something completely differ-ent“, summed up Peter Mletzko from Marketing.

Off to the Fortuna Mine! The hike was 4 km long – no problem for Duktus walkers!

“Glückauf” for some good food in front of the pithead building Got it! The treasure was discovered

In November 2012 the Czech sales company Duktus litinové systémy was relocated to Rudná, a small town 15 km from Prague, and in spring 2013 a 20 x 30 m marquee was set up on the company grounds for the storage of fittings. This was an occasion to have an open house day on 20 May 2013 and invite clients and friends of the company to have a look at the new premises. Interest was very high and over the course of the day more than 100 guests came along, mostly dealers, partners from engineering offices, water-works and construction companies. The atmos-phere was friendly, the food was tasty – grilled leg of pork was on offer – and the celebration went on into the night. Some fantastic music was pro-vided by the band of Jirí Mlynár, a sales repre-sentative for Duktus litinové systémy and a pas-sionate music fan.But the team from Rudná was not able to relax completely because the next day saw the start of the VODOVODY-KANALIZACE trade fair which is held in Prague every 2 years and at which Duktus was represented with an 80 square metre stand.

Running together and having fun

The “Gusseiserns” were there at the start again

Once again they succeeded in getting one of the sought-after starting places for the 15th Rennsteig Relay Race on 22 June 2013. The Gusseiserns, a team of colleagues from HTI Thüringen KG, EWE Armaturen Braunschweig, Duktus and clients of these companies from the water and wastewater industry in Thüringen, hit the road again for the third time in this competi-tive team run over 171.3 km in which this year a total of 235 relay teams took part. The newly formed relay team – for the first time the men had female support in the person of Romy Winter (HTI NL Erfurt) as cycling escort – managed to record a new best time for the team in this race. With excellent weather and good organisation by team leader Danny Hildebrandt, the Gusseiserns put in a remarkable performance on the day. The

starting runner was Steffen Gradl and after Karsten Walter (EWE Braunschweig) delivered a titanic performance in the penultimate stage, it became clear that this was going to be a record for the Gusseiserns and this finally became reali-ty when the final runner Matthias Apel reached the finishing line at Hörschel bei Eisenach shortly before 21.30 after 15 hours, 24 minutes and 45 seconds. Traditionally the stone which is passed from runner to runner is thrown into the river Wer-ra. The team were exultant, especially since they also achieved a respectable 146th place in the overall rankings. That they will do it again next year was clear to all.

J.P. Morgan Corporate Challenge Run in Frankfurt – Team Duktus takes part for the first time

On 12 June 2013 at 19:30 the starting pistol was fired for the J.P. Morgan Run. With 68,709 run-ning enthusiasts who are employees of 2,782 companies it was more than an hour before the men and women running for Team Duktus were even able to cross the starting line, and then a good half hour to reach the finish.The J.P. Morgan Run is run over 5.6 km through the inner city of Frankfurt in which values such as team spirit, communication, fellowship, fairness and health stand at the forefront. In addition the organisers are supporting a good cause. This year they collected 247,500 Euros for German disabled sport. In addition to Frankfurt, the J.P. Morgan Corporate Challenge also takes place in 7 cities in the United States and in London, Syd-ney, Singapore, Johannesburg and Shanghai and is thus the largest company run series in the world.Team Duktus with its 11 runners had what should be prized above all in this run: the fun of running. As it went so well with the first outing in the J.P. Morgan, the team are thinking of a repeat perfor-mance next year.

OUR CONGRATULATIONS TO

Looking over the hedge

Moveguide apprentice competition

APPRENTICE EXCHANGE BETWEEN DUKTUS AND TRM

In August 2013, 4 Duktus apprentices had an opportunity to take a look at the bigger picture and spend 3 days with TRM in Hall in the Tyrol to get some impressions of day-to-day working at our partner company. Nina Moos, Jacqueline Bablich, Stefan Brück and Kevin Scherz travelled to the Tyrol on 31 July 2013. “We were very warm-ly received”, said Stefan Brück, who was going to look at the TRM sales department, while Nina gathered experience in purchasing, Jacqueline got busy with payroll accounting and Kevin in-stalled a data line in the works council office alongside TRM works electricians. “We were de-lighted with the visit of this very nice team of 4

from Wetzlar”, reported TRM works council chair-man Armin Eberl. He took very good care of the apprentices and had a lot of praise to offer these young people. Nina Moos was inspired: “The works council and the management really made a lot of effort and, for example, they gave us the opportunity of visiting the silver mine in Schwaz. Together with our personnel manager Stefan Pohl and Dietmar Fischer, the TRM personnel and pur-chasing manager, we went 3 km into the mine on the tunnel railway. That was a fantastic experience and we learned a lot during the hour-long tour about medieval silver mining in the Tyrol.”During the 3 days, the 4 Duktus apprentices saw

many parallels, but also differences between the working routines of the two companies. That was the aim of the exchange – seeing how others work, making comparisons and broadening hori-zons.“A continuation of the exchange programme is planned“, said Armin Eberl, “because everybody benefits from this glimpse over the garden wall.”

“Exchange apprentices“ Stefan Brück, Jacqueline Bablich, Kevin Scherz and Nina Moos were inspired by the visit to TRM

In the nationwide Moveguide apprentice com-petition, which is conducted by BARMER GEK in the field of promoting health at the workplace, the apprentices from Duktus took an excellent second place.BARMER GEK has been staging this competi-tion for several years now. The idea is that ap-prentices will become initiators within their com-panies in matters of health and fitness and will give a helping hand to the company in promot-ing health at the workplace.This year 37 exciting projects were submitted to the jury. 225 apprentices took part. The Duktus team – Jacqueline Bablich, Stefan Brück, Hakki Orbay and Niklas Groh – scored points with plenty of good ideas and lots of motivation and gave a professional presentation to the jury.

“Workplace Health Management development programme at Duktus” was the theme. It showed per-capita costs of illness-related ab-sence, explained the potential savings which could be achieved with workplace health man-agement and presented the results of an em-ployee questionnaire. Here the apprentices were able to show some solid facts: workplace ergo-nomics and preventive check-ups were pre-ferred. Duktus Managing Director Stefan Weber was pleased with the success of the smart young talent: “Our apprentices as “manage-ment consultants“ have shown how – with fresh ideas, motivation and creativity – new impetus can be brought into a system and well-trodden paths can be enlivened with new problem-solv-ing approaches.”
