A meeting place for the world’s professionals Dear Readers The time since the last issue of PDi was published in mid July has been hectic, but also captivating and satisfying. The new Nordic demolition show DEMCON took up most of our time this summer, but it was worth it. The new show, held in Upplands Väsby a suburb of Stockholm, exceeded my expectations and was fantastic. Most of the Nordic suppliers exhibited and for the first demolition show in 10 years the number of visitors was very satisfactory, and a lot of business was conducted during the show’s two days. The history of DEMCON started in 1998 with its forerunner Demotech. This was three years after we started the Scandinavian demolition magazine Professionell Demolering and two years before Professional Demolition International was first published. Demotech was very popular with suppliers and contractors and was held again in 2000. But our plans to publish PDi, a magazine for the international demolition, concrete sawing and drilling, concrete floor grinding and polishing and recycling industries, took precedence over organizing and running Demotech. So we sold the rights to the show and concentrated instead on PDi magazine. But 10 years on we are in a much stronger position and have the resources to publish and develop our magazines as well as continue to organize and run DEMCON. The show will stay with us and the next edition is already set for 6-7 September 2012. The industries and related sectors mentioned earlier, as well as all the great people involved that my colleagues and I have worked with through the company S.C.O.P. since the late 1980s, gives us great inspiration to continue. I am also very happy that we now have much stronger bonds with the European Demolition Association. The EDA is growing stronger every year with straightforward planning and strong consciousness for improving the daily work of European demolition contractors. I am also pleased to introduce the European Demolition Association’s President and founder and chairman of the Italian demolition contractor Despe S.p.A. Giuseppe Panseri, as a new columnist for PDi. Together with our other representatives in IACDS, President Peter White and Executive Director of the US CSDA Pat O’Brien, I hope that PDi will become even more of an international platform and meeting place for the world’s professionals working within the mentioned sectors. This issue of PDi has features on the DEMCON show and the EDA autumn conference, plus a number of other major articles, including our annual concrete floor grinding and polishing feature, the hydrodemolition feature, several company profiles and many news releases. I wish you all continued success for the rest of the year.

Words from IACDS President
“A clear continuous strengthening of our work locally and internationally even in hard times” IACDS had its 18th meeting in April 2010 in Salzburg Austria which proved to be very successful. As said in my annual report the concrete drilling and sawing industry widely depends on the general construction industry, the real estate market and the public authorities work. Mankind has often been able to recover from this crisis and this again proves to be the case as we have seen a steady growth this year whether this will continue in the British market due to the government spending review in October we will have to see. Though most governments throughout Europe and the USA have had to cut back on public spending they are seeing the private markets steadily starting to grow again. Many of the contractors in the industry have had to cut back on purchasing capital equipment and new vehicles and this will have to alter soon as equipment gets older and more costly to keep repairing resulting in loss of productivity due to longer breakdown times. The membership from the various countries still stays strong in this economic climate, which shows that each national and the world association must be doing something right. Over the years the world association has been formed we have seen growth in local associations and the benefits that have been offered like insurance, training, exchange of knowledge, greater co-operation been companies, safety polices to name but a few. In the international scene there has been greater co-operation on the use of new ideas and technology. Discussions were taken at the international conference that a tightening of tolerances should again be looked at but it became evident that they were of an excellent standard now. It has been highlighted that some manufactures do not meet with IACDS machine specification rule but a large percentage of manufactures are abiding by these rules. On health and safety many countries are encountering problems with slurry and each country is finding a tighting of regulation on the disposal of slurry and high pH-value of clarified sewage water. Other countries felt that regulations regarding mineral dust and vibrations
were more important as employers are responsible for the health and safety of their employees, which form this point of view slurry is by far less important than vibrations and dust. The British Health and Safety wanted the guarding of drills on all drilling rigs but the problem lays in the fact that all drilling rigs are manufactured in Europe, USA and a few from China. All the Europe, USA and China manufactures meet the EU directive and guards and CE regulations were found to be unnecessary and cause more problems for the operative. At the Demcon show in September in Stockholm all the top manufactures of equipment were there and on 10 September when I attended it was an extremely good turnout by the demolition and drilling people. On the day I attended in the evening there was an excellent dinner where I spoke and said in my opinion there should be closer contact and cooperation between the EDA and IACDS. I know that other countries are trying to set up local shows for demolition and drilling and in the UK we are joining with others in the industry to put on a UK concrete show in February 2011 more details will follow. Hope that a lot of contractors have entered the Diamond Award 2011 which will be presented to the winners in Las Vegas at the World of Concrete in January 2011. Look forward to seeing all in Las Vegas 2011 if not at our next International meeting in Brugge at Unesco World Heritage in May 2011. If you which to visit the city’s web site go to www. brugge.be. I also take the opportunity to wish you all a Merry Christmas and a prospers New Year as issue 5 will be out early next year.
Best regards Peter White President IACDS

Words from O’Brien
Certification, Part Deux! special survey The Concrete Sawing & Drilling Association is poised to formally launch the CSDA Company Certification Program for sawing and drilling contractors. This 3-tiered audit program, developed by the CSDA Certification Committee, will complement highly successful CSDA Operator Certification Program that was launched in 1996. Operator Certification was a success with individual operators because of the vast amount of industry knowledge and experience of instructors, focused curriculum and networking opportunities for the students. However, because there was a need to provide owners, architects, engineers, general contractors and government officials with an industry wide prequalification tool to help improve the knowledge and skills of cutting contractors while enhancing their public image, Company Certification was developed. CSDA is uniquely qualified as an industry leader in the development of safety and training programs since 1993. More that 2,000 employees have graduated from the hands-on and online training programs. The Company Certification Program is the first of its kind in the industry and aims to educate the marketplace that hiring a certified company will eliminate risks associated with hiring a sawing and drilling contractor who may otherwise be seen as another unknown subcontractor. Sawing and drilling contractors can attain one, two or all three levels of certification. Level 1 has been devised to evaluate if a company meets the basic safety and financial requirements of the industry. To attain Level 2, a company must show it is undertaking sound operational and financial best practices in addition to the criteria set out for the first level, while providing evidence that the company has taken part in basic training or certification programs to better its employees and the
company as a whole. Level 3 will provide potential clients with proof that a company has a total quality management system in place, and that the contractor is committed to a high standard of safety and sound business practices. The program is an industryspecific quality audit that mirrors the standards set by accreditations such as ISO9000. In fact, by attaining Level 3 of the CSDA Company Certification Program, a company will automatically be ISO9000 compliant. The sawing and drilling segment of the construction and renovation industry is very much a niche market, with no accreditations or certifications specifically customized for concrete cutting contractors. By implementing this program, a company can present a seal of approval from an industry-recognized organization to prospective customers and differentiate themselves from competitors. The accreditation will also provide confidence for specifiers that the company is financially and operationally stable and meets a standard of excellence in its specific discipline. The goal for CSDA in this industrywide certification effort is to continue to advance the professionalism of sawing and drilling contractors in response to a growing call from general contractors and governmental officials to produce verification of a company’s skills and professional qualifications. CSDA continues to be true to its tag line, The Association of Cutting Professionals, by once again providing cutting contractors with a path to future accreditation that is increasingly becoming the norm. Best regards Patrick O’Brien Executive Director CSDA, US Concrete Sawing & Drilling Association

Ammann and Yanmar revises cooperation Ammann, a global market leader in asphalt mixing plants and road construction machinery, will in future focus on its global activities in road building. Yanmar, a globally active developer and manufacturer of diesel engines for maritime and land-based applications, agricultural and construction equipment and energy systems, will strengthen its European activities to become the sole manufacturer of miniexcavators in Saint-Dizier , France. The joint venture partners will retain post-split ties in specific markets. Ammann and Yanmar can look back on a successful collaboration lasting more than two decades. Both companies are now focusing in accordance with market demands of recent years.
Concrete evidence of success The founder of Australia’s specialist hire equipment company Kennards Concrete Care, Angus Kennard, has led to him being named as a state finalist in the prestigious Ernst & Young Entrepreneur of the Year award. The New South Wales final will be held in September, with the winner advancing to a national final, which will be followed by the judging of an international winner. The awards are the only global competition for those who are building and leading successful, growing and dynamic businesses. Kennards Concrete Care operates as a standalone, specialist division of the general hire company. Kennards Concrete Care’s main categories are surface preparation, cutting, drilling, cleaning, demolition, dust control and mixing and pumping. Products include dust collectors, mixers and pumps, grinders, planers and profilers, shot blasters, skid steer attachments, crushers and splitters, sweepers and scrubbers, trailers, mowers, scabblers and mini loaders “Concrete is the second used resource in the world behind water, but the equipment needed for working with it is very expensive,” said Angus Kennard. “I saw that while large contractors could
afford to buy what they needed, medium and small operators were trying to do jobs with equipment that was often inadequate.” The business model KCC adopted was not just to hire equipment, but also to use the knowledge, training and experience of staff to offer solutions to customers. “In a general hire company, staff know a small amount about a lot of equipment, whereas our team knows a lot about a small number of items,” said Angus Kennard.

Bobcat mourns passing of skid-steer inventor Bobcat has paid tribute to the co-inventor of the first skid-steer loader, Louis Keller, as the company mourns his passing on 11 July at the age of 87. Together with his brother Cyril, Louis invented the first skid-steer loader, which was based around a threewheeled loader they developed in 1957 for a turkey farmer near Rothsay in Minnesota, USA. “We were saddened to learn about the passing of Louis Keller, one of the inventors of the compact, three-wheeled machine that led to the first Bobcatbranded skid-steer loader,” said Bobcat Americas and Oceania President Rich Goldsbury. “Louis was among those honoured in 2004 as Bobcat received the ASAE ‘Historic Landmark’ award, a recognition reserved only for the most important agricultural innovations in American history. And two years ago, during our 50th anniversary, we celebrated the achievements of Louis and his brother along with everyone else who has helped make Bobcat a success over the last five decades.” The Keller Loader had two drive wheels and a rear caster wheel, and the brothers built half a dozen more in the first year. In September 1958, they were hired by the Melroe brothers at Melroe Manufacturing Company in Gwinner, North Dakota, which was later to become Bobcat Company. Using the brothers’ design, Melroe introduced the M60

By combining Hilti’s expertise in a wide range of application systems for construction professionals with Trimble’s broad portfolio of positioning technologies, Intelligent Construction Tools will deliver a new class of productivity solutions to the building construction industry.
Di-Star’s 16th anniversary In September the Ukrainian manufacturer of diamond tools Di-Star, based in Poltava, celebrated its 16th anniversary. The company grew out of UkrDiamant, a Ukrainian-Italian joint venture established in 1994 with the purpose of manufacturing premium diamond tools. With the benefit of European experience, imparted by the Italian side, high-quality raw materials and advanced production equipment, Ukr-Diamant quickly became the leading niche manufacturer in Ukraine. Following a major corporate overhaul in 1998, Ukr-Diamant was integrated into the emerging Di-Star Corporation. From that moment Ukr-Diamant marketed its products under the Di-Star brand name. The merger was completed in late 2007, with Ukr-Diamant ceasing to exist as an independent entity. Di-Star currently has 136 employees and 3,200m2 of manufacturing facilities, with shops for diamond segments and blades, research and development laboratories and storehouses. Di-Star’s monthly production capacity is 200,000 pieces for segments and 50,000 for blades.

Caterpillar plans factory in China Caterpillar has announced plans to expand its manufacturing presence in China to meet growing customer demand. The company will produce mini hydraulic excavator models in the under 8t range at the new facility in Wujiang. It will form part of Caterpillar’s Building Construction Products Division, which has manufacturing operations in the United States, Japan, Brazil and the United Kingdom. “China is the world’s largest market for excavators in the under 8t class, and the development of this new facility will better position Caterpillar to provide our customers in China with solutions that will help them succeed,” said Caterpillar Building Construction Products Division vice president Mary Bell.
Hilti back on track to growth The Hilti Group has reported a 5.6% increase in
sales in local currencies in the first eight months of 2010 compared to the same first eight months of the prior year. This growth, however, has been greatly set back by the rise in value of the Swiss franc. In Swiss francs sales rose by 2.5% from CHF 2,521 million to CHF 2,583 million. This upward trend has been driven by the launch of new products as well as growth in new areas of business. Hilti has benefited from the markets such as Asia and Latin America. In Europe, the Near/Middle East regions and in Africa the picture remains mixed: A number of markets have shown strong growth while in others sales are still clearly down. In North America the decline has stopped and, despite the persistently harsh economic climate, slight growth has been achieved. The trend of operating result and net profit has also been reversed. By the end of the second 4-month period the operating result reached CHF 167 million, an increase of CHF 115 million (+223%) over the same reporting period of the previous year. During this same period net profit rose by CHF 31 million to CHF 54 million (+132%). However, currency influences due to the strength of the Swiss franc had a negative impact amounting to CHF 70 million on net profit. Investments in research and development remained virtually unchanged up to the end of August at CHF 114 million. Compared to the previous year, the number of persons employed has risen slightly to a total of 19,977. “We have made very good headway with implementation of our stabilizing measures introduced in 2009 and assume that sales will continue to grow over the coming months,” said Hilti chief executive officer Bo Risberg. “These positive trends, however, must not be allowed

New Holland Construction’s E485B Demolition baptised in Rome It was a baptism of fire for the New Holland E485B, the first to be delivered in Italy. As shortly after arriving at Trulli Special Demolitions in Rome it was put straight to the test on an implosion demolition project on via Selva Candida. The demolition took place on the 21 June 2010 of the tallest building in the complex, at 35m high and with a total volume of 40,000m3. The remainder of the build-
ings will be mechanically demolished using tracked excavators equipped with grabs and shears. The operation begun in June of 2008 when over 150,000m3 of buildings were demolished and restarted in June 2010 with completion set for the end of July.
Newcomer in Demolition Trulli Special Demolitions of Rome, who directed the operations, are active throughout Italy. The firm is no newcomer to major demolition and urban renewal projects, having been involved in high profile projects including the demolition of the Olympic Velodrome, built in 1960, as well as the demolition of the old Ara Pacis museum. Specialising in mechanical demolitions, Trulli Special Demolitions has a fleet of machines that includes 13 excavators, with operating weights from 0.2t to 90t. The company Saig, based in Parma, was also instrumental in the via Selva Candida Complex project as a key partner in demolition using explosives. The E485B Demolition went into service on the Roman site with a 24m boom and a 14t grab, helping to remove the 320,000m3 of building material, much of it reinforced concrete. Choosing New Holland was made easier by the dealer Romana Diesel, who has been a distributor for the entire range of the Fiat group equipment since 2008.
Overall high quality “We began dealing with Romana Diesel quite a few years ago, when my father Vincenzino began his own business and turned to Mario Artusi, then chief at Romana Diesel, for purchasing some of the first lorries,” says Mr Trulli. “In 2008 Romana Diesel became a New Holland dealership so when we recently needed to buy a new demolition excavator we approached them and they recommended the E 485B Demolition to us. I must say that once again that our trust in Romana Diesel is very well deserved.” Mr Trulli was struck by the overall quality of the excavator, especially its power, stability and extremely low fuel consumption. The E485B Demolition is equipped with a low consumption Common Rail motor producing 258kW at 1850rpm. It has an operating weight of 50.3t and an advanced hydraulic system with

The rise of dust-related health and safety regulations has many contractors asking questions about dust control systems. Pullman Ermator wants to be the source for answers. Text & photos: Jim Parsons
For decades, many concrete cutting and drilling contractors treated vacuums like the pesky tag-along kid brother or sister, something that they would bring if they had to, just as long as it did not get in the way. But as the dangers of silicosis and other dust-related diseases have become better known, contractors have come to realize that vacuums are more than just a necessary evil. They are an important tool for safeguarding the health of all employees on the jobsite, not just those working in close proximity of the dust source.
No one-size-fits all Fredrik Åkermark, executive vice president for Pullman Ermator Corporation USA, also wants them to understand that just like tools, there is no one-size-fits-all vacuum and dust extraction system for every application. “Everyone wants to cut costs, but it doesn’t always mean you get what you need, particularly when it comes to health and safety,” says Åkermark. “You go to a specialist for quality grinding, polishing, and cutting equipment, so why not do the same thing when you need help with vacuums.” That message appears to be resonating with US contractors, which is good news for their workers and for the two-year old alliance of US floor care equipment manufacturer Pullman-Holt Corporation, and Sweden’s Pullman Ermator, a long time leader in dust extraction and vacuum technology. Based at Pullman-Holt’s existing facility in Tampa, Florida, Pullman Ermator serves as a North American gate-
way for the Swedish-built HEPA vacuums, dust extractors, and air scrubbers that have proven themselves in Europe’s abatement, restoration, remediation, and construction markets.
Coming to America Although Pullman Ermator products have been available across the Atlantic for several years, the company saw the need to raise its US profile due to trends such as the launch of the federal Occupational Health and Safety Administration’s National Emphasis Programme to address health hazards associated with occupational exposure to crystalline silica in January 2008. “We needed a partner who could help us with warehousing, technical support, and distribution,” says Åkermark. “Pullman-Holt was exactly what we were looking for. They had an excellent reputation in the US and shared our philosophy of using HEPA filtration to improve workplace safety.” Part of that philosophy includes rigorous testing at the Institute for Occupational Safety and Health of the German Social Accident Insurance to right-size HEPA filter design for airflow and a specific country’s standards. Follow-up tests have also validated the products’ performance in the field. A study by the University of Alabama that monitored dust levels generated by multiple operators using a floor grinder connected to a T8600, HEPA dust extractor, verified dust and silica levels below OSHA’s recommended rates. The twin-filter T8600 has also become Pullman Ermator’s most popular 3-phase vacuum, with a reliable 10m3/min airflow and adaptability with multiple grinders. For single-phase settings, the S26 (successor to the S2800) provides 7.3m3/min of airflow. When matched with an appropriately sized Pullman Ermator Pre-Separator, 90% of the material can be captured before reaching the vacuum’s pre-filter and HEPA filter units. And with the unique Longopac feature, waste can be quickly transferred to individually sealed disposal bags without having to shut down the vacuum. “These features help maximize airflow and avoid interruptions for filter
cleaning,” says Åkermark, who acknowledges that a replacement HEPA filter can cost almost as much as some lowend vacuums. “That vacuum may last only three months, after which you have to spend the same amount again for yet another unit,” he says. “Our vacuums don’t break down on job sites, so there is no lost time or compromised performance.”
Spreading the word Åkermark, who was previously Pullman Ermator’s international sales manager, moved to Tampa to head the US operation in 2007. His Swedish accent has yet to be heavily influenced by the Southern drawls normally associated with Florida’s Gulf Coast, as he spends much of his time on the road working with the company’s 15 concrete construction market distributors, and members of Pullman-Holt’s 100-member distributor network. “Our representatives are our biggest advantage,” says Åkermark. “They meet with dozens of contractors a week to see what they do, what they need, and how our products can help them. We also use their input to modify our machine designs.” Åkermark expects that education will remain an important part of the company’s efforts in the coming months as contractors continue to familiarize themselves with dust control issues, matching the right model vacuum for the type of machines they are using, power requirements, work volume power needs, and volume of work. If a contractor is working with only hand tools, for example, “a single-motor vacuum should be sufficient, and we have three to four models to choose from,” says Åkermark. Along with technology and application needs, Pullman Ermator is also helping familiarize contractors prepare with the changing regulatory environment. Last April, for example, the US Environmental Protection Agency implemented its Renovation, Repair and Painting Rule for work performed in housing and child occupied facilities built before 1978. Before contractors can disturb a surface area containing lead based paint in a pre1978 building, they must first become RRP certified and use specific work practices that prevent lead contamination, including containing dust with ventilated power tools connected to a HEPA vacuum. Åkermark expects that renovation work in older commercial buildings will eventually be governed by a similar standard. “We could easily see such a rule in the next two years,” he says. Less clear is the outlook for the US construction economy. Åkermark believes that it will be another two to three years before activity is on a sustainable upswing. “Contractors who have survived the past two years will probably stay in business,” he says. “They know what it takes to handle the really difficult times, so they’re ready to take what opportunities do come around. They’ve been focused on cutting costs and people. Now they’re focused on getting jobs.” Despite the economic uncertainty, Pullman Ermator remains fully committed to its US initiative.

in part to the RRP rule, first half 2010 sales doubled the company’s entire 2009 performance. Two new 17m3 and 34m3 air scrubbers, fitted with HEPA filters designed to US standards, will also debut this fall. The company is also looking to expand its distributor network, with particular emphasis on building its West Coast presence. “We feel contractors out there have a preference to buy locally,” says Åkermark. And, there’ll be more Swedish spoken around Tampa, as Pullman Ermator owner and president Torbjörn Bengtsson has relocated to the city to be closer to the company’s primary growth market. The move toward HEPA filter vacuum systems may also get an extra boost from demographics. Unlike a lot of industries that are aging, Åkermark says that the US concrete cutting and polishing business is demographically young, which also bodes well for Pullman Ermator’s prospects. “They are more accepting of the health impacts of dust, and new technology, such as HEPA filters, so they should be very interested in our products,” he says. But regardless of a contractor’s age, the number one priority will be having a vacuum that performs eight hours a day and more. “Our vacuums may not be the most beautiful or the cheapest,” says Åkermark. “But they always work. Our customers can count on that.”

DEMCON right in the bull’s eye The Nordic demolition, concrete cutting and recycling exhibition DEMCON was held on 9-10 September 2010 at the InfraCity Business Centre in Stockholm.
The first DEMCON exhibition was very successful and attracted close to 70 exhibitors in the fields of demolition, concrete sawing and drilling, concrete floor grinding and polishing, recycling and related sectors. DEMCON is a show for pure professionals in these sectors and attracted over 2,100 visitors from all over the Nordic region of Europe. The majority of visitors attended the show on both days.
Many concrete cutters About 15% of the visitors came from Nordic countries other then Sweden. Another 10% were from the rest of Europe. There were also visiting groups from Russia, China, Japan, Australia, India and USA. Concrete sawing and drilling contractors were dominant among the visitors and many also work with light demolition using remotely controlled demolition robots and compact equipment. Traditional demolition and recycling contractors made up the second largest visitor group followed by a number of companies working in concrete floor grinding and polishing, renovation, cleaning of hazardous material, industrial cleaning and hydrodemolition. During the last decade earth moving contractors have also started to take on demolition and recycling jobs. The show attracted some of these companies and the objective is to attract more of this group at the next DEMCON.
Good business The rental show ExpoRent was also held in parallel with DEMCON where an additional 43 companies displayed their products and services. In the DEMCON outdoor area some companies demonstrated their equipment alongside the Nordic final of the Tyrolit Cutting Pro Competition. A unique slurry collector named Slurry Box attracted visitors as this novel device drained slurry and produced small compact and dry concrete bricks. There were very positive comments from exhibitors and visitors about the show and several exhibitors also said that sales were very good. A number of exhibitors sold far more than they had expected and one exhibitor said that they had broken the sales goal set for the show by five times. By the time the gates closed at 4 pm on Friday the 10 September it had already been decided that DEMCON would go on a two year cycle at InfraCity north of Stockholm with the next show set for 6-7 September 2012.
Several associations gathered

In addition to the main two day DEMCON exhibition at InfraCity, several associations had their meetings and seminars parallel to the show. The biggest was the European Demolition Association with over 70 delegates attending who also witnessed PDi • Issue 4 - 2010 • September - October
the launch of the EDA High Reach Guide. A full report about the EDA meeting is on pages 26-27 of this issue. Also the Swedish associations for demolition contractors and concrete sawing and drilling held their meeting as well as the Swedish Rental Association, Hyrex. In the evening of the 9 September a large gala dinner was held in the Scandic Hotel InfraCity Ballroom. Close to 400 guests attended, including delegates from all the associations as well as a large number of exhibitors at the show. During the dinner speeches were given by EDA President Giuseppe Panseri, the International Association of Concrete Drillers and Sawers President Peter White, Swedish Demolition Association President Lars Sandström, the Swedish Veteran Association of Concrete Sawers and Drillers spokesman Gunnar Landborg and Sune Almqvist President of the Rental Association Hyrex. Alfred Landl from Tyrolit was conducting the prize giving ceremony for the winners of the Nordic final in the Tyrolit Cutting Pro Competition, which was held in the fair ground earlier in the day. Michael Atkinson from Komatsu Europe proclaimed the winner of the Komatsu competition the same day. The gala dinner had The Bonke Gang band playing a mix of music from the 1960s and 70s as well as traditional Swedish songs and host for the evening was PDi magazine editor-in-chief Jan Hermansson.

Reformatte The European Demolition As-
sociation conference that coincided with the DEMCON exhibition marked a change in format that marked the event as one of the best in recent years. PDi’s Mark Anthony reports. According to the old adage, if it ain’t broke, don’t fix it. But, in its search for the perfect conference format, the secretariat of the European Demolition Association is not above tweaking its approach to enhance the quality of its proven product. Running alongside the inaugural DEMCON exhibition, the stripped-down version of the event gave the conference a new and welcome added dimension. And this wasn’t the only welcome change to the familiar format of these events.
A perfect conference format However, the EDA Autumn Conference began along traditional lines with a welcome reception at the Infra City Hotel’s Winter Garden in the evening followed by the beginning of the formal meeting the following morning. And here the changes were evident from the start. While EDA President Giuseppe Panseri was presiding over his first conference since has accession to the role earlier this year, he was joined on stage by moderator and multi-lingual TV presenter, Lauara Donadoni who played a key role in ensuring that the reduced conference stayed on track and on time. The opening presentation was given by Alfonso Oltra of the Instituto de Biomecanica, Universidad de Valenci who gave details of the EU Project Alert scheme that is seeking to reduce the impact of asbestos Below Alfonso Oltra from Instituto de Biomecanica.

exposure to workers across a broad range of industry sectors including demolition. Oltra was followed onto the podium by John Woodward, vice president of the Institute of Demolition Engineers and managing director of C&D Consultancy in the UK. Woodward, an EDA veteran, gave an insight into the command, control and communications measures set in place by himself and one of his clients – Armac Group - following a major fire at a UK school. A video of Woodward’s presentation can be viewed by visiting: http://ow.ly/2JZgf Maintaining the British theme, Woodward was followed by Komatsu’s Michael Atkinson – one of the event sponsors – who then made way for Stefano Chiavalon who gave a fantastic insight into the decommissioning of the historic Monteluce Hospital in the heart of Perugia, and how local community liaison turned a critical project into an opportunity for contractor General Smontaggi. From Italy, the presentations moved closer to the conference’s home with G. Tscherning A/S Tue Brix explaining how his company tackled the demolition of a heavily polluted sulphuric acid plant in Helsingborg, Sweden. Completing the morning session was Ferrari Demolition’s Daniel Rieber who explained how his company used a rope reeving system to bring down a mining head frame in France, and the use of hydraulic jacks to fell a French tower block. A video of the tower block demolition can be viewed by visiting: http:// ow.ly/2SY5x Pilar de la Cruz, principal of Voladuras y Demoliciones and EDA vice-president, opened the afternoon session with a presentation on the technical implosion of a pair of silos in Ciudad Real before sponsor Åke Sonerud of OilQuick explained how his company’s quick hitch system could pay for itself in saved machine time. And the EDA had time for another first before lunch with Erith Group’s David Darsey becoming the first acting National Federation of Demolition Contractors’ president to address the EDA. Together with colleague Stuart Accleton, Darsey looked at how his company had tackled the partial demolition and

welcome) of its new innovations with a panel debate moderated by Laura Donadoni. The debate posed a simple question: “In the light of the current economic crisis, is it better to have a vertical, specialised business model or a broad business model with skills in a number of sectors. The panel, which included Anna Jarnehammar from the IVL Environmental Research Institute in Sweden, Maurizio Massaia, president of the NAD in Italy, John Woodward, IDE vice-president, and Jan Hermansson, editor of PDi magazine in Sweden, discussed this question at some length, agreeing that a broad skill base was the best way to provide stability in an uncertain economic period. In truth, each of the subsequent questions that expounded upon that original proposition was worthy of a debate of its own; and I would hope that future panel debates are given greater prominence in the EDA’s conference programme. As delegates retired to their rooms to make ready for the evening’s Gala Dinner, the technical committee gathered to discuss the important and timely subject of training for high reach excavator operators. Once again, the Secretariat had managed to pull together a broad and interesting range of presentations from an equally broad range of companies and countries. And, with the introduction of the panel
debate session, has opened the doors to allow delegates to have a greater say in the proceedings and in how the future of the European demolition business is shaped in years to come.
Guidance Unveiled A cocktail reception in the midst of the DEMCON exhibition’s equipment exhibits provided an appropriate backdrop for the official launch of the EDA’s High Reach Guidance. Watching the development of the European Demolition Association’s High Reach Guidance has been like viewing the growth of a rare and unusual flower. It’s been almost five years since the EDA took the seed that was the National Federation of Demolition Contractors’ original guidance. That seed has been cross-pollinated with input from around a dozen countries, and lovingly nurtured by gardener-in-chief Stefano Panseri. And now, after several years of behindthe-scenes tending, Panseri has finally brought his bloom to a waiting world, launching the EDA guidance, appropriately, at the DEMCON exhibition in Stockholm, Sweden. It has been a labour of love for Panseri who has seen the guidance through numerous incarnations, rewrites and modifications. But the launch of the

At a time when most facets of the construction and demolition industry seem mired in the doldrums, the market for hydrodemolition services and products is a welcome bright spot. PDi’s Jim Parsons reports. All pictures on this page is showing the new Aqua Cutter 710V from Aquajet Systems AB
28
Patrik Andersson, Key Account Manager for Aquajet, Holsbybrunn, Sweden, says that general knowledge of and interest in hydrodemolition is growing worldwide as more people compare the process with the microcracks or broken rebars that can be caused by jackhammers.
Growing and upgrading A good indicator of the market’s strength, Andersson adds, is how quickly existing customers look to upgrade their equipment. He reports that for past few years, customers in northern Europe and Canada that started up with hydrodemolition a couple of years ago are now upgrading their equipment to get the latest models and technology. The U.S. has also been a relatively good market for hydrodemolition. Bob Nittinger President of American Hydro, Baltimore, Md., credits the US$700 billion federal Stimulus programme enacted last year, much of which is being used to refurbish hundreds and other infrastructure “This has been one of our best markets, along with garages and nuclear power plants,” says Nittinger. He adds that 2010 has been his company’s best year ever, and the backlog for the following year is the best it’s ever been at this time. Nittinger, whose company like many others in the U.S. designs and builds its own cutting robots, says that hydrodemolition has also proven preferable to mechanical demolition for large, complex projects. For example, American Hydro prepared the 13500 m2 (145,000 ft2) vertical surface of the San Vincente Dam near San Diego, Cal., as part of a long-term project to raise the dam by 36 m (117 ft) and double its reservoir capacity. Growing awareness of silica dust issues and worker health will only reinforce interest in hydrodemolition as the U.S. infrastructure market recovers. When it does, however, contractors will need to be ready. “Rather than just looking to contractors for cutting services, customers now want a complete package, including control, water recycling and reuse, and clean-up,” says Nittinger. “It makes sense to put the risk on contractors like us because we’re the experts.” A decade of explosive development should also make China an attractive market for hydrodemolition. “There are a lot of concrete roads there that are due to be refurbished, “ says Andersson. “We feel that the future for hydrodemolition is really good. If the market stays strong through the rest of 2010, 2011 will be even better.”

New products for the new market Aquajet is helping contractors prepare for the next wave of hydrodemolition projects with products such as the newest version of its Aqua Cutter robot, the 710V. Introduced at Bauma 2010, the Aqua Cutter 710V builds on the proven features of Aquajet’s versatile HVD robot by providing a sturdier base to extend free vertical reach to 7 m, with an option for widths of up to 4 m. The 710 also features updated versions of Aquajet’s patented Intelligent Sensor Control (ISC) and Evolution Smart Lance (ESL) systems that enhance the robot’s flexibility. Other features include extended track length and width, increased engine power with fuelsaving function, hybrid drive compatibility, a gull-wing opening hood, and revised equipment layout for easier service accessibility. “The new Aqua Cutter robot is incorporates the features customers need to compete successfully in today’s demanding hydrodemolition market by handling a wide range of working situations,” says Andersson. In addition, Aquajet recently released all-new multi-purpose Aqua Spine frame, designed specifically for applications that conventional robots can’t access. “Development of this frame is the result of experience with many previous special applications, and helps expand the usability of many standard parts,” says Andersson. Another hydrodemolition equipment leader, Conjet AB of Haning, Sweden, also has several new robots on the market. The new electrically powered Robot 365 MPA can remove concrete from numerous surfaces above and underneath the robot with minimal set up time. With a rigid design and improved multi-purpose arm, which reaches up to 6.4m above the robot and 3.3 m down the side, the Robot 365 MPA can operate with a reaction force up to 2000N, equivalent to the force of a water jet generated by a 550kW (700 HP) high-pressure water pump. The Robot 365 is also available with a Heavy Duty Arm (HDA) capable of handling a reaction force of 3000N generated by a larger 750kW (1000HP) pump. The Robot 365 has outstanding stability and can withstand these high

reaction forces while safely operating the feed beam with its jetting lance in any position. In addition, the Robot 365 can be fitted with an optional tower mast attachment on its front or side and is capable of reaching down and operating as much as 6m below the robot. The Robot 365 is based on a two-wheel steer and drive, four-wheel carrier. The width between the drive wheels and the level of the steering wheels are hydraulically adjustable. The drive wheels can be manually mounted in three different positions in order to either maximize stability or improve the reach below the robot. For less accessible hydrodemolition locations, Conjet now offers the Robot 324. With its robotic arm the 1100kg Robot 324 can work on horizontal and vertical surfaces as well as inside tubes and circular tunnels as narrow as 900mm. Due to its low weight, which is evenly distributed by the rubber tracks, the Robot 324 can be operated safely and easily on access platforms and scaffoldings. Conjet has also extended its comprehensive range of equipment with the ‘Nalta’ Jetframe 101, the world’s smallest and lightest hydrodemolition unit. Nalta, a colloquial expression from Lappland in northern Sweden meaning “small,” is an appropriate term for this lightweight, highly manoeuvrable jetframe. The cutting head and feed beam section weigh 14 kg and 6 kg, respectively. Each of the hydraulically controlled step units, which are fixed to each end of the feed beam and automatically climb up and down standard scaffold tubes, weigh 9 kg each. The jetframe’s trolleymounted hydraulic control unit weighs 90kg. The Nalta operator remotely controls all functions of the Jetframe 101 at a safe distance from the working area, eliminating the need for bulky and heavily protective clothing. Conjet vice president Lars-Göran Nilsson says that the Nalta will eliminate the accidents that can occur with the hazardous hand lancing operations. The product has already proved to be considerably more productive in pre-launch contract trials. “We are replacing the dangerous hand held lancing operations and making them safer with our new and revolutionary ‘Nalta’ Jetframe,” says Nilsson. “Contractors that have so far

used the Nalta, during on-site contract trials have been very impressed with its safety and performance.” With a hand lance pump of 120 kW, generating 250N reaction force, production with the Nalta will reach between two to three times higher than with a hand lance. And because the Nalta can withstand a greater reaction force of 600N, compared to 250N for a handheld lance, higher-powered pumps can be used, increasing productivity even further up to 5 to 6 times. “Nalta is also very easy and quick to set up and can work continuously, so there is far less downtime compared to hand lancing, where operators have to stop and rest every 20 minutes or so,” adds Nilsson.

N.E.T. had to clean about 4,200 m2 from the inner surface of the 1.8m to 3 m diameter penstock with its Conjet 324 Robot working on gradients up to 18°.
Conjet cleans up at Glenlee Power Station The 12MW Glenlee hydro-electric power station in Scotland is part of the 106.5MW Galloway HydroElectric power scheme, which was the first large scale integrated hydro-electricity supply complex in the UK when it was built and commissioned in the mid 1930s. A 60km long network of lochs, dams, tunnels, aquaducts, pipelines and rivers interconnect six power stations in a cascade system, which reuses the water several times for power generation. Each station reuses the water that has been discharged by the one above to generate electricity. A dam blocks the natural outflow of Loch Doon and acts as the main storage reservoir at the top of the scheme, which has a drop of 210m over its length. Glenlee is the fifth of the six power stations in the interlinking renewable energy scheme that covers a large area of Galloway and South Ayrshire. Water for Glenlee Power Station gathers in Loch Clatteringshaws and flows through a 6km long tunnel to a portal control valve above the power station. From
here water plunges 125m down the hillside through a 570m long steel penstock of varying diameter to the station’s twin 6MW turbines and out of tailrace valves and into a spillway, for discharge into the River Dee. From here the discharged water combines with natural river flows to the downstream Loch Ken, which acts as the reservoir for the last power station in the scheme at Tongland. Outflow from Tongland Power Station rejoins the lower reaches of the River Dee and flows into the Solway Firth at Kirkcudbright Bay. The Glenlee penstock was in need of cleaning and repainting and power station operator Scottish Power Generation Ltd awarded a contract for its refurbishment to the specialist contractor Concrete Repairs Ltd based in Falkirk. The flange bolted steel pipeline had not been cleaned and painted internally for over 70 years, since it was installed in the 1930s. CRL believed the internal cleaning and paint removal could be done with high-pressure
water jetting and contacted N.E.T. Waterjet Ltd, a contractor based in Meigle, Perthshire, specialising in ultra high pressure water technology and diamond drilling and sawing. “I believed it was initially feasible to use hand held high-pressure water jetting lances in the penstock’s varying diameters and gradients to remove the old paint coating and peat lying in the bottom, but there was a risk for the operators,” says N.E.T. managing director Tom Wallace. “So I looked at the possibility of adapting a robot, normally used for the hydrodemolition of concrete, and contacted Castellan, the UK agent for Conjet hydrodemolition equipment in Sweden. As soon as I saw the compact 324 Robot I knew it would work, using the optional Hammelmann blast or rotor head instead of the normal concrete hydrodemolition lance. CRL accepted my price and I ordered a Conjet 324 Robot from Castellan and it arrived on site in May.” N.E.T. used its new Conjet 324, with optional rotor head, to remove the build up of debris, old paint coating up to 4mm thick and unexpected original mill scale, back to a clean and smooth metal surface. The company had about 4,200m2 to clean from the inner surface of the penstock in diameters from top to bottom of 3m, 2.7m, 2.4m and twin 1.8m and on varying gradients from 1:100 up to the steepest 18°. CRL removed the flange bolted expansion joints and butterfly valves in the penstock to provide N.E.T. access at several points for the Conjet 324, which was supplied with water at a pressure of 2,500 bar and flow of 25 litres/min from one of N.E.T.’s existing 250kW Hammelmann 120 high-pressure pumps. “We are working a single shift seven days a week

The sequence is repeated continuously. The Conjet Robot has been superb and worked very well and is a lot safer and about three times faster than using hand lancing.”
Largest hydrodemolition contract for CanMar Contracting Ontario, Canada has for many years, traditionally relied on jackhammers for restoration of deteriorated concrete. But Toronto-based CanMar Contracting Ltd started the changeover to hydrodemolition techniques with the delivery of three Aquacutter Evolution robots from Aquajet Systems. Over the past two years CanMar has completed more than 55,741 m2 of garage slab restoration in Toronto using the three Aquacutter robots, achieving approximately 13,935 m2/ robot/year. “Working a typical 10 hour day, we are able to achieve on average of 93 m2/day using the Aquajet robot, “ said CanMar hydrodemolition manager. “A single

New partners on floor saws
In Germany machine and tool manufacturer Rellok Cutting Solutions GmbH from Celle has entered a partnership with Wilnsdorf-based Dr. Schulze GmbH to distribute Rellok’s floor saws. The partnership agreement is for Dr. Schulze acting as Rellok’s agent in Eastern Europe, Asia and Africa. Sales in Western Europe and certain regions of the Middle East will be handled by Rellok.
While Dr. Schulze has been operating for more than 25 years, Rellok is a new name in the concrete sawing industry and a spin-off from MB Holding Company LLC based in Oman. It was established this year with the objective of supplying machines, tools and customized solutions for professional users.
Four models
Rellok’s current line of floor saws includes four models. A 33kW Deutz 3-cylinder diesel engine powers the basic model RSF 330. The cutting roller is directly driven by a V-belt. The machine reaches a cutting depth of 170mm with a 500mm diameter blade. Retrofit kits for up to 1m blades are available and blades can be lifted hydraulically. The floor saw is easy to position above the cut thanks to a hydraulically operated support wheel, which lifts the rear axle for a short time, to facilitate lateral movements. The rear axle can be adjusted in both directions by 6° and ensures exact directional stability, even if there is a lateral slope. Cooling and rinsing water can be fed by a pressurized water or self-priming pump. The larger RSF 450, with a rated capacity of 45kW, is powered by a 4-cylinder Perkins turbo diesel. The cutting roller is mechanically driven by a two-stage angle transmission, with its setting optimized for a blade diameter range of 800 to 1,200mm. Unlike a direct drive, the cutting roller’s speed does not need adjustment for different blade diameters. The maximum cutting depth reaches 300 and 480mm for 800 and 1,200 mm blades respectively. The blade is lifted by a central hydraulic cylinder. Thanks to a steering knuckle, the RSF 450 is easy to set up and operate. Pressurized water or impeller pump is used for water supply.
Worldwide promotion
Ride-on machines
Having its research, development and production facilities located in the same area, Rellok is able to develop and supply machines and tools to non-standard specifications. The new manufacturer is betting on partnerships with recognized companies to promote its brand worldwide and its dealership agreement with Dr.Schulze is the first step towards this goal. More dealership contracts are in the pipeline.
The RSF 620 and RSF 750 are fully hydraulic machines. Travel drive and steering, saw blade drive and lowering are regulated by a fully hydraulic unit driven by Perkins 4-cylinder turbo diesel engines at 62 and 75kW respectively. Continuously adjustable hydraulic motors drive the cutting rollers. This guarantees the optimum speed for each blade diameter. If required, direction of the blade rotation can be changed. The cutting side is changed by turning the blade
drive console. The RSF 620 has a maximum cutting depth of 480mm and the bigger RSF 750 goes to 625 mm. Water is fed through the cutting roller and blade flanges. Both floor saws are of ride-on type, intended for heavy-duty operation. The RSF 620 and 750 are believed to be the first machines in their class where the operator sits above the driving motor and not behind it. The elevated position enables a better view of the sight vanes and cutting surface. A special emphasis is laid on ergonomics of the floor saws to ensure their maintenance and repair. All the machines have hydraulic travelling gears to prevent operator fatigue, if long continuous cutting is required. The drive motors comply with the EU Stage IIIa and EPA Tier 3 emission standards. The entire line is equipped with connectors for a hydraulic suction unit to remove the slurry out of the cut.
Attachment kit In the near future Rellok plans to top up its floor sawing range with new models and a variety of accessories. Several kits will be available for the fully hydraulic machines. The attachment kit for grooving is assembled on the back of the machine. It creates ridges in concrete or asphalt surfaces to improve the water transport and prevent aqua planning. There is also an attachment kit for cutting lateral joints in green concrete. The device is side-mounted, with a rail-guided cutting drive. The whole cut can be made in one go. Another attachment kit has two cutting drives on a line. This solution allows cutting a longitudinal joint to two different depths, or cutting and expanding it at the same time. There is also an option to attach a hydraulic drilling machine to the back of the floor saw for core drilling tasks.

Dynaset for demolition New machines from Bobcat The Finnish company Dynaset is claimed to be the world’s leading manufacturer of hydraulic generators, power washers and compressors. The company’s hydraulically powered machines produce electricity, high pressure water and compressed air. Dynaset’s hydraulic equipment generates power that increases productivity and work efficiency without utilizing extra engines. Its zero-emission products transform hydraulic power into electricity, high pressure water, compressed air, magnetic or vibration force by simply connecting two hoses. Dynaset’s solutions save users a lot of time and cost by eliminating the need for a separate engine, fuel or onsite maintenance. The excellent power-to-weight ratio guarantees easy on-board installation on any kind of heavy-duty machinery.
Hydraulic high-pressure dust suppression The company’s hydraulic high-pressure water pump uses a patented piston-to-hydraulic-piston principle without any rotating parts. Dynaset’s high-pressure dust suppression system atomizes water to mist to control dust emission on demolition sites and recycling plants. Low-water flow effectively cleans the air and provides for better breathability and visibility, without flooding the ground and making the surroundings muddy. The system is ideal for use with crushers, jaw breakers, hammer drills, or screens. Customers can also produce an umbrella dust suppression system using a rotating nozzle to spray the misted water around a 30m area. The high pressure water dust suppression kit also includes a pressure washing gun with hose reel for maintenance and clean-up applications.

More Heger Titan Xflow! With the launch of the Heger Titan Xflow C3 Heger is now able to provide this patented technology for the full range of professional floor sawing machines. A scientific test on a project on highway A5 in southwestern Germany has proven the extraordinary speed and life, which can be reached using this technology. Even the river gravel aggregates from the Rhine could not stop the performance of this blade. Due to the dotted structure the side friction
has been reduced significantly. Therefore the machine power can focus on the cutting edge of the blade and does not lose its capacity on the useless side friction. As another effect the dots allow the cooling water to get faster to the cutting area, which results in significantly longer life. The new Xflow C3 has been designed for machines from 20 – 50kW operating in concrete with hard aggregates. Some customers in Holland with whom we did the final in field tests found their
projects could be finished in half the estimated time with improved lifetime performance. The extra benefit of the new metal bond is the environment friendly HECO technology, which completely avoids cobalt. The use of cobalt is specifically hazardous in the production process. The very fine powders pollute the air and even sophisticated filter systems cannot fully preserve the emission.

Concrete floor grinding and polishing services continue to grow in popularity. But the enormous hype in the establishment of new manufacturers and brands that the market experienced a few years ago seems to have faded.
Nothing for fortune seekers Some players arrived and disappeared just as fast, and we can expect to see more brands vanish from the market in the near future. Professional concrete floor grinding and polishing equipment is not a goldmine where anyone without enough effort and knowledge can get involved and hope to grab a piece of the business. To remain in this business it needs a very serious attitude towards the method, the users, the tools and the service. The suppliers need to learn to go all the way to survive. The market is in a state of consolidation. But there is one exception. What has appeared is a growing interest for OEM manufacturing from established manufacturers resulting in more brands. It is mainly larger local and international suppliers to the concrete sawing and drilling industry as well as the demolition industry that have started to market their own brands of concrete floor grinding and polishing equipment. Many of these companies manufacture their own diamond tools and also offer grinding and polishing equipment to increase the sales of diamond tools. Others take up branded grinding and polishing equipment as a complement or to increase their other products.
Many diamond tool manufacturers Where we see a never-ending boost is in diamond tools for concrete floor grinding and polishing. There are lots of local diamond tool manufacturers supplying tools for their clients. Today we are also experiencing a wave of overseas diamond tools mainly coming from China. It first started with the diamond powder or complete segments but today there are among five to ten larger Chinese suppliers that are taking international market share. The marketing activities are to a large extent coming directly from China and the tools

are sold under the original Chinese brand, yet the concentration is on the tool and not so much on the machinery.
Environmental improvements The numbers of pure flooring companies are steadily increasing all over the world. Epoxy and other types of coatings have a very strong lead and are doing their best to cope with concrete grinding and polishing methods’ environmental advantages. Examples are less harmful coatings easier to apply and maintain. But still it is hard to crack the basic fact that concrete floor grinding has eliminated one step, which is the coating and treating concrete. The polishing phase is made with environmentally friendly methods. The only part of the concrete floor grinding procedure where more effort is needed is to contain the fine dust before it reaches machine operators. Using traditional coatings also creates dust during the removal of the old coating and during the preparation of the surface for the new coating, but not as much if the concrete floor is going to be prepared as a final flooring product. The professional manufacturers of dust extracting equipment perform continuous development in finding new and more efficient ways to deal with dust. Many of these manufacturers have co-operations with the manufacturers of floor grinding equipment. Despite this some manufacturers of floor grinding equipment have invested in their own production of dust extraction equipment, tailor made for floor grinding purposes. As the dust collection is a considerably important part of the whole concrete floor grinding process it is recommended that contractors consider how this should be done. A collector developed for floor grinding is best and should have the best filtering characteristic that can handle hazardous particles. This
is best found among sole manufacturers of dust extraction equipment. Besides pure flooring contractors, the floor grinding and polishing services are increasingly taken up between concrete sawing and drilling contractors and also among light demolition and renovation contractors. Several national branch association like US CSDA, UK and Swedish sawing and drilling associations as well as the international umbrella association IACDS, have brought up the subject on their agendas.
New products from HTC
Hiperfloor made with Husqvarna machines.
But what is new since last year’s concrete floor grinding and polishing feature? PDi has contact some players and a few have shared their experiences. The biggest is still HTC Sweden AB, founded by Håkan Thysell in 1992 who has a 60% stake. The investment company 3i has a 35% share. The number of employees is now 175. The company has one production plant and four fully owned subsidiaries, three sales offices and 42 agents globally with main markets being Europe and USA. The range consists of floor grinders in 15 different sizes from 270mm up to 2500mm. Dust extractors in five different sizes, specially designed for floor grinders. HTC has built a new training facility in Sweden. In addition all subsidiaries conduct training and education at their offices in their countries and most of the HTC dealers offer the same. HTC main clients are floor contractors and the construction industry. Concrete sawing and drilling, cleaning and demolition industry are also considered very important customer segments. HTC has a very comprehensive range of products and the focus on professional floor contractors has been clear in recent years. But since Bauma this year the company has strengthened its efforts towards concrete sawing and drilling, demolition and cleaning contractors by launching a completely new line of products called Greyline. Greyline consist of four floor preparation grinding machines and two dust extractors.
Husqvarna increase focus on popular training sessions Another manufacturer to respond is Husqvarna Construction Products. The company is the world leader in diamond tools and equipment for the construction and stone industries. The Husqvarna Group has 2,100 employees. Husqvarna has 10 main factories and the products are sold in approximately 70 countries through its own sales companies or distributors. Main markets are Europe, North America, and Australia. Husqvarna also hold several Husqvarna skills and training seminars each year. They offer these courses to existing customers, retail customers, and those looking to get started in the industry. During the seminars the diversity that Husqvarna’s range of grinders and tooling are capable of are taught. This ranges from removal of thick coatings and rain-damaged concrete to Above three pictures showing floor grinders from Italian Klindex.

high-end decorative finishes such as HiPERFLOOR. Due to the success of the seminars Husqvarna has decided to increase their frequency. No new models have been launched recently, but the range consists of five floor grinders and two dust extractors.
New products from Klindex, a growing Italian player A player that has increased its exposure on the international arena is Italian manufacturer Klindex srl. Klindex is located with its factory in Manoppello outside Pescara on the east coast of Italy. It was founded in 1998 and the owners are Ercole and Enio Bibiano. The company has a current turn over of EUR 11 Million with 50 employees. The main markets are Europe, Eastern Europe, Middle East, Asia, Australia and North America. The range consists of about 20 different models for concrete floor grinding and polishing from 1.7 to 25 HP. Klindex offer training sessions every week for their clients free of charge. The manufacturer recently launched their biggest floor grinder Expander 1000, which has a grinding diameter of 1 m. Klindex clients are mainly found among floor specialists which are also believed to have the strongest potential by the company.
Two new machines from Scanmaskin Another manufacturer that has strengthened its position on the export market is Scanmaskin AB. The company moved about a year ago in to new premises outside Gothenburg,

which have had a strong effect on the development of new products. The release pace has been kept high during the last 18 months and just before the Nordic demolition show DEMCON Scanmaskin released their largest machine ever, the Scan Combiflex 1000 RC. This is a real heavyweight machine and has the same robustness as all the other Scanmaskin models. Scan Combiflex 1000 RC is made for large grinding areas. According to Scanmaskin, this is the first grinding machine that combines the strength between the grinding method with four grind plates rotating on a large plate that rotates in the opposite direction. This provides the possibility to grind with higher speed and more weight on the machine. The machine is equipped with a radio-controlled operating system that allows the operator to concentrate on moving the dust collector and managing cables while the machine is working. It is also easy to transport the machine between places, thanks to the radio control. The SC 1000RC is battery powered, which makes it easy to move the wheels for steering. New from Scanmaskin is also ScanCombiflex 450. The machine has been developed for the rental businesses, floor layers and smaller renovating businesses. According to Scanmaskin ScanCombiflex 450 is more flexible, simpler to use and much cheaper then other comparable models. The efficiency is still the same as the ScanCombiflex 45 that remains in the range. With ScanCombiflex 450 it is possible to remove lighter coatings with SC-Tiger Silver. Rough and fine grinding can be accommodated with the Scanmaskin different Snap-On tools. It can be used for dry polishing of concrete and terrazzo. It is also suitable for grinding wooden floors.

Polished concrete floor still minor Polishing concrete floor as final flooring products is here to stay. And most manufacturers of floor grinding machines offer their own methods even though it was HTC who started this business segment by launching their Superfloor system some 20 years ago. But still polished concrete floors are not that common and all major manufacturers agree to that. “The market for polished concrete is growing as the market starts to see the benefits and the functionalities gained from the floors. Epoxy floors and dry shake toppings are still dominating and it is estimated that polished concrete represents only 2% of the world’s concrete floor so there is still huge potential,” says HTC Sweden’s Business Unit Manager Rental and Floor preparation Henrik Pettersson. “We are certain though that the market will grow as a lot of countries don’t yet fully understand the benefits with floor grinders. The alternative to grinders is often methods that destroy the floors, in the end that’s expensive. Also new rules and regulations like vibration and noise, makes other methods difficult to use.” Husqvarna Construction Products global product manager Joakim Leff-Hallstein believes polished concrete floor stands for a slightly higher share. “I guess we are looking at 2 - 3% of the flooring market. Carpet and tiles dominate the market for commercial and residential while epoxy is dominating the industrial market,” says Joakim Leff-Hallstein. Joakim was appointed global product manager for Husqvarna Construction Products at the beginning of August this year and worked earlier as export manager for HTC. Husqvarna believes that concrete preparation and polishing will continue to grow as concrete grinding is the most efficient way to remove glue, contaminants from the surface and repair rain damaged concrete “Polishing the concrete is becoming more popular due to its low maintenance, which reduces costs for shopping centres, distribution centres, warehouses and large retail stores. The positives are putting more of our product down (HiPERFLOOR) which increase the market share and general knowledge that you no longer need to cover your structural slab with costly floor coverings,” says LeffHallstein. Klindex marketing manager Roberto Bibiano does not mention any particular share for polished concrete, but believes it has huge potential. “Polished concrete floors interest all our clients today and in particular in Europe and I believe we will see a tremendous growth,” says Roberto Bibiano.
The hype not good for anyone But what about the hype in the market and how does that affect the business? “I believe that competition in general is something good as it helps the total market to grow and in this case it makes the market aware of the benefits working with floor grinders. However, competition is good as long as every player respects other companies’ patents and innovations,” says Henrik Pettersson at HTC. Joakim Leff-Hallstein agrees. “The negatives are that more and more companies bringing out machinery and flooring systems with no industry knowledge, so operators don’t get the significant training they need to satisfactory finish floors, which brings the concrete floor finishing market down as consumers see it as a flooring system that does not work.” Roberto Bibiano at Klindex says that today very few manufacturers cover half the market. “I think this situation will more or less remain and in the future not more then five to six manufacturers will remain. All the other manufacturers that have showed up recently will have difficulties to compete.”
Tasteful concrete floors at Air Force Museum
Old faithful low-speed surface grinders continue to be valuable U.S. General Equipment Company president Dennis Von Ruden shares some of his thoughts about low speed grinders versus the new high-speed models. With the introduction of high-speed diamond grinders in recent years, many users have tossed other types of equipment aside, hoping that the new, flashy machines will be a catch-all for concrete polishing and grinding applications. But rather than being distracted by the latest hype, contractors should take care to find the correct solution for a particular job. The answer to the question at hand may not always be the newest machine, but instead could be the old faithful ones.
High versus low Over the years, there have been countless instances where one technology was replaced by another. The high-speed grinders became a huge buzzword within the industry as the growth of concrete polishing jobs exploded. Although the machines came with a steep price tag, many people were impressed by the newfound ability to quickly tackle concrete grinding and polishing jobs. Suddenly, everyone could work like the professionals, or could they? With the development of a quicker machine, some may wonder why anyone would still use a low-speed grinder for concrete grinding and polishing. Can a high-speed unit do the same job more quickly? The answer is yes, but quicker is not always better. With speed comes the increased risk of inflicting costly damage to the surface, especially when the user is not a well-trained professional. Low-speed grinders, however, work more slowly so the operator does not accidentally remove too much material or lose control. Although low-speed grinders have been available for almost 50 years, the continuous development of new attachments makes them an extremely versatile machine, even more so than high-speed diamond grinders. Not only are the machines capable of grinding concrete, but new polishing attachments also allow them to complete polishing applications. Additionally, since high rotational speeds make it much
46
more difficult for a machine to penetrate surface coatings, low-speed grinders are the only practical option for removing them.
Different strokes for different folks Both types of grinders have their place in the industry. High-speed machines are typically suited for welltrained professionals, while low-speed grinders work well for small contractors and do-it-yourself exponents. But since there has been reduced emphasis on the use of low-speed surface grinders, there are a few things that should and should not be done with to these machines.
Do understand the job at hand Low-speed surface grinders may be versatile, but they are not a solution to all removal applications. For example, as a grinder they are designed to remove a minimal amount of concrete from the surface. Therefore, to remove 12mm of concrete on a 1,000m2 floor, a low-speed surface grinder is not the ideal machine.
Don’tuse incorrect power sources As obvious as it may seem the unit should have the correct power source for the location. Engine-powered grinders are typically the best option for outdoor applications, since electric-powered units will not work at an outdoor location that has no electricity. Electricpowered machines also will not suffice for indoor locations that do not have the correct electrical power available. In these cases, a propane-powered machine might be the ideal choice. Since electric-powered units often have high amperage and voltage requirements, it is important to understand jobsite setup and whether the machine needs a 115 or 230 V power source and if it requires a 15 or 20 A circuit.
Do understand the operation of the machine Contractors will have a pleasant experience operating

In Linköping the Swedish Air Force Museum is located. The museum re-opened June 12, 2010 after having undergone an extensive renovation and expansion. The exhibition hall houses a large number of aircrafts from the last 100 years, or from the pioneers of aviation to today’s JAS 39 Gripen as said on the museum website. The aircrafts are arranged and presented on a 5100 m2 high gloss HTC Superfloor that provides a powerful first impression. Kjell Pettersson på Stångå Clean AB was responsible for grinding the floor. During the first two months since the re-opening the museum has had more visitors than it previously had in a year and the museum’s personnel is very pleased with the floor. In the beginning however they were a bit worried that the shiny floor would steal too much of the attention from the aircrafts and they therefore considered a less shiny version of HTC Superfloor. Before the renovation the concrete surface was covered with a thick layer of green epoxy so it is not hard to grasp the enormous difference low-speed surface grinders if they are aware of proper operating techniques. For example, extra weight, such as cinder blocks or sandbags, can be added to the machine in order to increase the material removal rate. This applies to almost every attachment configuration with the exception of wire brushes. Since most low-speed grinders are designed for the addition of weights, check the manual for the manufacturer’s suggestions. Also, many try to increase the material removal rate by pushing and pulling the machine back and forth. Instead, a more effective technique is to slowly pivot the machine about its wheels.
Do not use the wrong attachment for the job Quite frequently operators are not satisfied with their surface grinder’s results, and the problem is often caused by the use of an incorrect attachment. For example, one of the most common mistakes is trying to use silicon-carbide stones to remove or grind floor coatings. The stones will work for only a short while before they clog. In this case, scraper attachments may work best. Many types of attachments have been developed to meet the needs of various applications, and most manufacturers post information on their Web sites regarding the proper use of attachments.
Do dispose of materials properly With today’s strict environmental regulations, contractors and do-it-yourselfers alike must consider the disposal of materials from the grinding process. If the surface being removed is contaminated by oil, chemicals, radiation or other hazardous materials, it must be disposed of according to relevant government regulations.
Don’t forget to maintain the machine Low-speed surface grinders are fairly simple machines. Besides regular engine maintenance on gas-powered units, there are not many components to service. But because the concrete dust is extremely abrasive, there are several important lubrication needs.
the floor has done. Kjell Pettersson tells that they had two HTC 950 RX when grinding the floor. “In total it was between 28-30 tonnes of grinding dust, or 6 kg grinding dust per square meter”, says Kjell. With a HTC 650 HDX Stångå Clean AB also grinded the 900 m2 parquet floor in the restaurant and library.
www.htc-floorsystems.com
One of the most common overlooked maintenance items is lubricating the transmission bearings. The problem exists because operators do not take the time to remove excess concrete dust around the bearings after use. Eventually, the grease fittings become hidden from sight, and dust continues to contaminate the bearings. This results in total bearing failure, which may consequently damage expensive transmission components. To combat this problem, some manufacturers have incorporated a remote lubrication system designed to simplify maintenance, but even this cannot prevent all abuse. Attachments are also key to operational success and should wear evenly and should be replaced as the contact surface approaches the attachment discs. The service life of attachments will vary based on the application and use. For example, a set of silicon carbide grinding stones may last approximately 450 m? , while a diamond system could cover up to 4500 m? before replacement is needed.
Tried and true Although new machines have taken much of the recent attention, low-speed surface grinders will continue to stand the test of time. Thanks to their versatility, they can still be a productive solution, rather than an endangered species. By understanding these simple tips, contractors can realize the full potential of these machines and utilize them to achieve consistent success.

Making way for Centraal in Rotterdam A new inner-city transport interchange called Centraal is being built in Rotterdam, Holland that requires the demolition of the old 1960’s section with 8,000t of reinforced concrete. The demolition contractor, Struijk-Groep, from Krimpen aan de Lek, was awarded the contract. “First we had to break into the upper layer, which was up to 1.3m thick in parts, so we could use two telescopic mobile cranes to lower our demolition machines and tools down onto the flat work surface, 35m underground. Here the excavator and boom tools were often less than one metre away from the running trains,” says Struijk-Groep joint managing director Allard Struijk. The site was divided into two working
areas with a 45t Komatsu PC450 excavator with quick-coupler and a free-rotating, 6.4t ACDE-Okada TSW 1800 VFR concrete cutter as the main machine working on the lower base level. The PC450 also used a silenced, 4t, G 100 City rammer hydraulic hammer, a 2.5 m3 demolition backhoe and sorting grab. In the lower sections a Fiat-Hitachi 135, a zero tail swing excavator alternating with a silenced Okada TOP 100a hydraulic hammer, a 1.4t Okada TSW 950 VFR concrete crusher;, worked alongside a Fiat-Hitachi mini excavator, equipped with an ACDE DMS 330 hydraulic hammer and a T175 Bobcat with shovel loader. The demolished material, has to be lifted from the pit and stockpiled in the upper area
of the site. At the stockpile a Fiat-Hitachi 350 excavator with a 2.8t Okada OSC 100 V Euro concrete crusher was used to separate the concrete and reinforcement prior to delivery of the separate materials to specialist recycling companies.

Doosan’s new Telehandlers Doosan Infracore Construction Equipment has entered the high capacity telehandler market with the launch of a new range of four models for Europe, the Middle East and Africa. Offering maximum lift heights of 10 m and lifting capacities from 7 to 21t, the new Doosan telehandlers combine the flexibility of telescopic handlers with the power of wheeled loaders, the efficiency of rough terrain forklifts and the reach of mobile cranes. They can be combined with many more attachments than comparable cranes or forklifts, allowing operators to use one machine for carrying out jobs that would normally require two or more different machines. Using buckets up to 4.5 m3, the Doosan telehandlers are also suited to loading applications. The smallest model in the range is the DT70, which has a maximum lift capacity of 7 t, a maximum lift height of 9.65 m and a maximum forward reach of 5.4 m. The next
larger model, the DT120, offers a maximum lift capacity of 12 t, a maximum lift height of 9.4 m and a maximum forward reach of 4.9 m. The two largest models, the DT160 and the DT210, both have a maximum lift height of 10.2 m and maximum forward reach of 5.15 m, with maximum lift capacities of 16 and 21 t respectively.

Italian manufacturer brings dusty issue to light Dust is an undesirable but inevitable by-product of every demolition project. The process of bringing down a building always generates a large amount of dust. What makes the matter worse is that this extremely harmful substance is often invisible. It takes a beam of light to see the real scale of the problem.
Italian Tower Light s.r.l., originally a lighting machinery manufacturer, was equipped enough to see both challenges and opportunities that dust suppression harbours to branch out into this business three years ago. “There is a great demand for hightech dust control solutions. A man with a hose will soon become extinct on demolition sites,” says Tower Light export manager Alessandro Rossi.
Italian enlightenment in the 21st century Tower Light is well known in the sector of mobile lighting equipment. Its products can be found in 60 countries, including Australia. Founded in 1997 in Villanova d’Ardenghi near Milan, Tower Light quickly grew into an international player, with a staff of 85 and branches in the UK and France. With a 50-model range of lighting towers, the Italian manufacturer is prepared to satisfy the most fanciful request for illumination equipment. Tower Light, however, never sells its mobile units to end-users, preferring instead to deal with distributors and rental companies. In 2007 when the manufacturer noticed that demand for dust control solutions among its customers began to snowball, it decided to seize the opportunity to diversify into this business.
Award winning range Three years on, dust control remains a largely uncharted territory, with no apparent leader or commonly accepted standards. “This is a fast growing market with enormous potential, and Tower Light aims to secure a pole position in it,” says Alessandro Rossi. The newcomer grasped the nettle and developed the popular Dust Fighter range, which currently includes 10 models. To market its dust control equipment, Tower Light established a daughter company called DF Ecology. Apart from water nebulizers, indispensable on construction and demolition sites, it offers road safety solutions like wheel washers for cars and trucks. Tower Light’s foray into dust abatement is proving successful so far, with the Dust Fighter range winning the ‘Rental product of the year’ award from the European Rental Association in 2010.

particles and make them settle on the ground. The most remarkable thing about this technique is that it does not generate mud. Among the Dust Fighter range, Alessandro Rossi singles out the DF7500 MPT as a complete package solution. This trailer based nebulizer is equipped with a generator and a large capacity water tank, which keeps the unit going for 1.5 hours. DF 7500 MPT’s body can be electrically rotated by 360° using remote control. Superlight VT1 is the company’s bestselling lighting system. The 9m Superlight VT1 is the first mobile tower with vertical mast. Before it was invented and marketed by Tower Light, lighting towers had used horizontal masts whose main problem was safety. There was always the danger of the mast falling down due to a safety pin malfunction. The Superlight VT1, with its vertical telescopic mast, is very easy and safe to operate. The tower is complete with a hydraulic lifting system to raise and fold down the mast and a powerful low noise generator with a running time of 60 hours.
Money well saved Tower Light missed Bauma 2010, preferring instead to organize an ‘Open Week’ at its factory. This proved a good decision as the Icelandic volcano eruption all but ruined the world’s biggest construction equipment show. The Open Week turned out to be a good marketing move, with many potential customers attending to check out Tower Light’s lighting and dust control machinery. However, the Italian manufacturer did not forgo exhibiting at all trade shows and besides exhibiting at Demcon in Sweden, Tower Light’s products can also be seen at Ecomondo this year, and Samoter and Conexpo in 2011.

Duztech cannons from Sweden goes abroad
Bobcat loader removes spoil in tunnelling project A Bobcat T300 compact tracked loader has provided a unique, cost-effective solution for removing spoil in the construction of a pedestrian tunnel at the site of the 14th century monastery of Santa Caterina del Sasso, a popular destination for pilgrims at the base of a sheer cliff face on the eastern shore of Lake Maggiore in Italy. The tunnel will link to a new lift system taking visitors down from the car park, making it easier for visiting the monastery. Previously access was by steep steps down 50m from the car park to the monastery entrance. The works were commissioned by the Architectural Heritage Sector of the Province of Varese, with the collaboration of the Achille Balossi Restelli Engineering Company in Milan. At the planning stage, it was clear that removing spoil from the tunnel would severely restrict the progress of the work. The inaccessible entrance, little room to manoeuvre and the need to lower a machine to a specific point, using only the construction site crane, narrowed the choice down to a compact loader. It was believed no other type of machine would have been able to work in the conditions. The contractors opted for a Bobcat T300 compact tracked loader, fitted with an anti-
particulate filter by Bobcat dealer MAIE to reduce emissions in the tunnel. Together with a range of attachments, the T300 loader was purchased by Sondrio-based specialist excavation contractor ACCISA SpA, which acted as subcontractor to the project’s main contractor I.CO.P. SpA, based in Udine. “We were looking for a compact loader which could remove spoil as quickly as possible. The machine had to be powerful and have lifting capacities suitable for working in difficult conditions, said ACCISA representative Massimiliano Duca, “Weight was another problem as we had to partially dismantle the loader and lower the components to the tunnel entrance with a crane, which had a maximum capacity of 1.6t. With the assistance of MAIE, the loader was dismantled so that the largest and heaviest assembly, the main chassis, could be safely lifted by the crane. The machine was then reassembled at the tunnel entrance to carry out the work and, at the end of the job, it was again dismantled to remove it from site.”

Low-emission demolition on hospital grounds The grounds of the city hospital in Stuttgart, Germany have been turned into a major construction site. Right next to the Katharinen hospital the new gynaecological and paediatric clinic is under construction. This new building is currently the country’s biggest hospital construction site.
FWA put their trust in Caterpillar demolition excavators and Atlas Copco hydraulic breakers and silent demolition tools. Owing to the long-standing co-operation with the attachment manufacturer both parties benefit from continual innovation.
Special restrictions
The last new entry of FWA’s equipment pool is the Atlas Copco CC 6000 U hydraulic CombiCutter launched at Bauma 2010. The company has been actively involved in the development of the cutter and purchased the first one. Just one day after the end of the exhibition the cutter was used for the demolition for the new hospital building in Stuttgart. “With its large jaw and the enormous power the new CC 6000 U is a big reinforcement for our machine pool,” says Fischer Group technical manager, Joachim Schmid. “And just like all other silent demolition tools it is quite silent and can therefore be used without problem in town centres.” The use of the new CombiCutter allows the heavily reinforced concrete to be demolished much faster. “The proven design with two cylinders is applied on the CC 6000, which of course also preserves the excavators during demolition work,” adds managing partner Georg Fischer. Apart from the new CC 6000 U also a new CC 3300 B with box-type jaw is used on the construction site. Other Atlas Copco attachments are used for the demolition job including two CC 3300 hydraulic CombiCutters, one with universal arm and one with scrap cutting arm, and three heavy-duty hydraulic breakers weighing 3t to 7t.
Before work could start first of all the former administration and storage building of the hospital had to be demolished. This demolition job had to comply with special restrictions curtailing the amount of dust, noise and vibrations produced during demolition work because normal hospital work had to continue unhindered. Contractor FWA Fischer Weilheim Abbruch was given this large-scale demolition job by the provincial capital Stuttgart. Within the short construction period some 50,000m3 of walled-in space above and below ground had to be demolished and properly disposed. Work started with extensive gutting and sanitation activities. Apart from the usual sanitation of pollutant wastes, such as synthetic mineral fibres and substances containing tar, a lot of sanitation work was needed to clear asbestos. Experts continuously monitored the work and in the end gave their clearance for the demolition work.
Water spray to reduce dust In order to reduce the amount of dust produced during demolition FWA used their own water spray systems directly attached to the excavators to bind the dust near where it is produced.

Metal+Waste Recycling invests in DustBoss Following extensive comparisons and appraisals of mobile dust suppression equipment in the UK Metal + Waste Recycling Limited has taken delivery of 10 DustBoss DB-60s from UK importer Inmalo. Five units are wheeled and the others are skid versions, with the machines being deployed in a number of the company’s locations throughout the UK. Metal + Waste has always paid particular attention to the environmental impact dust can cause, with tailor-made static dust suppression systems installed at all their operations to ensure maximum control of the problem. However, the company has found that static dust suppression is not always sufficient and has taken steps to seek an efficient and cost-effective solution by investing in DustBoss units. “We had tested the market and looked at a number of mobile dust suppressors,” said Metal + Waste director John Rice. “We were impressed with the build quality and efficacy of the DustBoss DB-60. Inmalo loaned us a unit on demonstration
and we were impressed with its performance, which convinced us that these were the dust suppressors we should invest in. The mobility of the DustBoss DB-60 means that we can take it to any area on our sites set it up and have it running in no time at all. We are finding that the dust-suppressed areas covered are far greater than we can achieve with just a static system and, in effect, we can take our dust suppression to where it is needed most and move it on to another area quickly and easily.” The DB-60 uses a series of 30 nozzles to atomize water droplets to the optimum size for maximum particle attraction and coverage, launching them with a 25HP fan. The ducted fan delivers 850m3/ min, giving it a throw of more than 60m. The DB-60 has an adjustable elevation from 0-50° and a 40° oscillating head, which can cover nearly half an acre and the wheeled mobile unit can be easily located to wherever it is specifically needed.

panel, all mounted on a cement base. The Fog Maker 10 bar low-pressure version is best to suppress dust in mines, quarries, steel plants, construction sites, power plants, and industrial facilities, while the 60 bar high pressure one is ideally used in vast open places such as outdoor concerts, soccer fields and public parks. Fog Maker is controlled from a panel, set on the machine, but it can also be remotely controlled.
Fog Maker is a new product launched by Idrotech, part of the Idrobase Group specializing in manufacturing fogging systems. This new equipment is mainly used to reduce dust as it uses an industrial atomizing system that shoots billions of small droplets into the air up to 60 m with a rotation field of 320° through misting nozzles, situated in a ring on the exit of a powerful fan. Fog Maker is available in two versions known as Elephant and Giraffe. The first is characterised by a short column and is more powerful, while the second one is more versatile and equipped with a hydraulic column, making it similar to a giraffe stretching out its neck, which can lift the fan up to a height of 5.2 m. Both models come complete with a fogging module, inlet water filter, and a control

Shibuya’s way of e PDi’s Editor Andrei Bushmarin had the privilege to visit Japan and in particular the Shibuya Company in Hiroshima. This was not just an exciting trip it also brought about reflections over what happened in Hiroshima on 6 August 1945 when over 129 000 people were killed instantly in the nuclear blast and how fast the city has recovered from the tragedy. Today Hiroshima is proclaimed the city of peace. Deputy Manager Koji Sawamoto, President Norikazu Shibuya, Vice-President Toshihiko Suganuma;
Everyone who has been to Japan and visited the Peace Memorial Park in Hiroshima will not forget the experience. Mind rebels at the premeditated atrocity of a-bombing. It is a horrifying lesson of technology serving destruction, not progress. But Hiroshima is also a reassuring and uplifting example of how quick a nation can rise out of radioactive ashes to rebuild their life and their cities. Hiroshima is now a vibrant Japanese metropolis, full of skyscrapers, shopping malls, green parks and picturesque waterways. Its gem is Miyajima, or God’s island nestled in Hiroshima Bay, where deer freely roam the streets and there are no graveyards because nobody thinks of dying there. The President of Shibuya Company Ltd, Norikazu Shibuya, who survived the blast by being out of Hiroshima, guided PDi’s Andrei Bushmarin through the past and present of his home city and his company.
From agriculture to concrete drilling Some of his relatives perished in the blast, but Norikazu Shibuya’s immediate family survived, and in 1952, his father Katsuji Shibuya, started a shop Noueki Shokai, which sold agricultural machines. Tractors and muck spreaders remained his business until 1967 when he saw a core drilling machine and recognized the potential of concrete drilling and sawing. It was how Shibuya Trading Co. Ltd, a dealer in core drilling systems, was born. Shibuya upgraded its status to manufacturer two years later when it designed and began to produce core drills TS-1 and TS-2. The period from 1955 through 1973 in Japan was that of rapid economic growth, driven, not the least, by close cooperation between the former adversaries. As a tacit apology, the USA opened up its market to Japanese products and introduced Japan to cutting-edge Western technologies. Before long, the possibilities of concrete drilling and sawing caught the imagination of Japanese contractors, and booming demand for equipment of this kind propelled Shibuya from a small-time producer with a two-model range into a multimillion dollar company.
No order is too tall Over the years Shibuya Company Ltd has acquired the reputation of a manufacturer of state-of-the-art drilling machines. In
The Genbaku Dome in Hiroshima’s Peace Memorial Park. 1982 when it realized the importance of dovetailing drill rig characteristics with those of core bits, Shibuya began to develop and produce diamond tooling. Also in the early 80s, Shibuya built Japan’s first electric wall saw SS-2000 and from then on continued to devise various types of wall sawing equipment. A Japanese contractor is not an easy one, and Shibuya often has to design machines and tools to challenging, even contradictory, specifications. “We rise to every challenge being posed to us by our specifiers,” says Norikazu Shibuya. “If we are requested to increase a motor’s power while reducing its size, we set about doing just that. We never shirk from a difficult task and always put in every effort to find a best solution for Deer on the streets of Miyajima
the customer. This is Shibuya’s way to build long-term relationship with clients”. This policy, along with an excellent after-sale service, has helped Shibuya secure an impressive 60% share of the domestic market. 70% of Shibuya output is sold within Japan, with the remainder being exported to North America, Europe, Oceania, Asia and South Africa.
Simple is beautiful Shibuya’s guiding principle in machine development is that everyone should be able to operate it. Even a heavy-handed PDi editor did reasonably well in his first hands-on training in core drilling. Japanese contractors want their drilling equipment to be compact and lightweight, and Shibuya has designed a range of light models TS-092, TS-132 and TS-162 to meet those requirements. In the international market, however, demand is higher for bigger drill rigs like TS-252 and TS-403. Shibuya’s most recent release is the hand-held drill motor RH 1532, which is only being sold in North America at present. Its main difference from the existing RH 1531 model is the electronic control, which helps the operator stay within the rated load and prevents the motor from overheating. If an inexperienced driller goes beyond the rated capacity, the electronic control simply shuts the motor down to avoid permanent damage to it. The 220/240V version of the RH 1532 will soon be released for the European market. Encouraged by customer feedback on the RH 1532, Shibuya has decided to carry on with the idea, and to equip its entire line of drill rigs with electronic control. “It will make our drills even easier in operation. I always say that simple is beautiful, we build our machines around this principle,” says Norikazu Shibuya.

player. The manufacturer is a long time member of Japan’s and North America’s Concrete Sawing and Drilling Associations. Japan’s association headed by Norikazu Shibuya is, in turn, one of the founding members of the International Association of Concrete Drillers and Sawers. “The best thing about associations is networking. It allows members to stay abreast of the industry goings-on and create an extended web of contacts,” says Norikazu Shibuya. At the moment, JCSDA, whose members gather twice a year to exchange the latest news, is more of a social club than an association. This stands to change soon as JCSDA is now working towards a greater formalization of its activities.
Dry techniques are the future Protection and preservation of nature is one of the world’s ongoing concerns. Japan’s new government has already stressed the importance of using eco-friendly techniques, like dry sawing and drilling, on construction projects. Shibuya Company strongly believes that dry techniques will shape the future of the global concrete cutting industry. The manufacturer has staked its claim in this burgeoning market with TSK-092, TSK-162 and TSK402 drill rigs that are suited to both dry and wet applications. Shibuya’s standard wall saw SS-300R can also be converted to dry sawing mode by attaching it to a special 760mm blade guard connected with a vacuum cleaner. Development of machines and tools for drilling and cutting of very hard materials like sapphire and quartz glass is another field that Shibuya sees as promising. The manufacturer will be stepping up its efforts in these areas as Japan’s economy snails out of the recession.

“ASHINE ON YOU CHINESE DIAMOND”
China has established itself as a big player in diamond tooling business. This immense country is home to an almost countless number of companies that produce and export diamond consumables into all corners of the globe. PDi’s Andrei Bushmarin reports.
Ashine uses the Chinese equipment to manufacture diamond tools.
58
There is, however, the issue of Chinese quality, which is known to falter occasionally. Xiamen-based Ashine Diamond seeks to reverse this pattern by offering tools of consistently high quality.
Building trust rather than tools The Ashine story started in 1993 when Richard Deng, a graduate of Sichuan University with a Master’s degree in synthetic diamond technology, set up a small workshop called Sanjinfeng to produce segments for stone blades. Before launching into his own business, the young graduate worked for a while in the stone industry as a technician. At the start-up stage, Sanjinfeng’s payroll consisted of just two workers. In 2002 when the business began to take off for the fledgling manufacturer, the name was changed to a catchier Ashine to convey the spirit of youthfulness and enterprise that was and remains essential to the company. Ashine’s other corporate values include professional integrity, industriousness and a strict environmental policy. Ashine is committed to minimizing the environmental impact of its operations by using fewer natural resources and less energy. Significantly, despite the fierce competition the company faces domestically, it is European manufacturers that Ashine considers its principle rivals. To set itself apart from other contenders, Ashine has placed long-term relationship with customers above short-term profits. “Ashine sees itself as not just a manu-

facturer of diamond tools as we aim to become a reliable and attentive partner for our clients who listens to their needs,” says Richard Deng. “Winning customer trust is a crucial element in our strategy to turn around the public opinion of Chinese quality, and to give the words ‘made in China’ a new prouder meaning. I know this business, I love diamond tools, and I love my job!”
High end is the target Seventeen years on, Ashine has grown into a US$12million/ year business. Its 150-strong team manufactures and sells diamond tipped tools into more than 20 countries through a network of some 50 dealers and distributors. The main focus is, unsurprisingly, on the markets of the USA, Germany, Italy, Japan, and Australia, but Ashine also eyes with much interest the BRIC countries. Unlike

many other Chinese players, Ashine targets the high end of diamond consumables with a wide choice of laser-welded and hot-pressed blades, core bits, diamond wires, and grinding and polishing pads and discs. It is the latter of those that many Ashineâ&#x20AC;&#x2122;s customers have begun to identify the company with. Ashine claims to have pioneered the production of tools for concrete grinding and polishing in China, and to have gained quite an experience in this field. Ashine operates two plants, with a total floor area of 7,000m2, to produce tools for stone and construction applications respectively. The smaller stone plant runs three production lines, while the bigger one has 10 lines to produce a big variety of diamond tools for construction. The production volume currently totals 500,000 pieces per month. No major expansion is in the pipeline, with Ashineâ&#x20AC;&#x2122;s target now being to keep the quality of the existing catalogue on the up. True to its pro-China views, Ashine only uses the equipment of Chinese origin to manufacture its tools. Tool quality is, too, tested on China-made instruments. The only concession Ashine is prepared to make concerns tool safety performance, which it evaluates, using machines from Germany. Tools that come off Ashineâ&#x20AC;&#x2122;s

trademark grinding and polishing tools. Ashine considers Bauma a unique opportunity for manufacturers to exhibit their products to a world wide audience. Trade shows are a pivotal part of Ashineâ&#x20AC;&#x2122;s marketing strategy, and it has already announced its plans to take part in the industryâ&#x20AC;&#x2122;s biggest events, including 2010â&#x20AC;&#x2122;s Concrete Show, Bauma China and World of Concrete in 2011.
Bauma and other shows Ashine used Bauma 2010 to show a range of new products. Its stand featured the Turbo line of 300 to 900mm laser-welded blades for reinforced concrete, a range of 500-1200mm wall saw blades, and the companyâ&#x20AC;&#x2122;s

MB’s new Universal Quick Coupling MB S.p.A., considered the world leader in the production and sales of crusher buckets based in Vicenza, Italy, has added the Universal Quick Coupling to its line of equipment. Available in seven versions, depending on the excavator and the pin on which it is assembled, the new Universal Quick Coupling allows all kinds of equipment, such as crusher buckets, hammers, and drills, to be quickly fitted to an excavator. This new coupling improves pick-up geometry by reducing the distance between
the excavator arm and the equipment used, thereby speeding up jobs carried out on site. The strain on the excavator is also diminished, due to reduction of more than 50% of the weight compared to traditional couplings. The new Universal Quick Coupling weighs about 80 kg, compared to 150 kg of other couplings. This universal coupling is quick and versatile and makes assembly operations easy thanks to the possibility of quickly assembling the pieces of equipment on the front and back. MB S.p.A. occupies a place in the front line in the demolition and recycling sector, and the constant research ensures the company is always one step ahead by offering work tools that are an absolute must at construction sites. The equipment offered by the company has made it extremely competitive and well known at the international level in just a few years.

Priceless Royal Doulton panels saved by D-Drill In the UK a team of drillers has safely removed priceless pieces of tiled art at the old Royal Victoria Infirmary hospital. Two experts from Stanleybased company D-Drill removed several collections of Royal Doulton panels, which displayed a number of scenes from famous nursery rhymes. The tiles, which are worth thousands of pounds, were mounted across the RVI hospital’s children ward in Edwardian times and had remained there until the children’s ward closed in 2009. Demolition had started on the site and D-Drill was asked to remove the tiles without damage, so that some could be remounted on the walls of the new hospital. “After looking at the on-site situation and realising that there were old steel conduits within the rendered wall behind the tiled panels, we decided that the only way to carry out this delicate operation was to cut a chase around the perimeter of the panels through the plaster and render with a 110volt diamond hand held saw,” says D-Drill representative John Emberson. “We
then fed the diamond wire into the chase and onto the wire saw drive machine. “We had to use a bespoke pulley wheel system to control the diamond wire as it cut down behind the panels without cutting the tiles. There were 68 panels to take down and we needed to make sure they were not too heavy to transport and handle. “The process started by gluing a board and holding a frame on the face of the tiles, and then cutting down behind the panels so that there was nothing left bar the original tile cement. That meant they could then be moved safely. We’re delighted with the outcome because they are beautiful tiles and they were a part of the RVI’s history. Now most have gone into storage although three have been remounted and add a touch of the past to a modern hospital.” “The key with any project like this is to make sure any damage is minimal,” said Eura Conservation director Robert Turner, who com-
missioned D-Drill. “This project was difficult and we couldn’t have relied on the traditional method of removing the panels tile by tile, because there would have been too many breakages. Instead, we drafted in John Emberson with his 30 years’ experience along with D-Drill’s specialist equip-
ment to enable us to remove the whole display as one fixed piece. Between us, we ensured there was only very minor damage. Several of the pieces have now been placed in the new hospital and others will follow at a later date.”

Practical “Aiyonthology” from Okada When Apple launched its iPhone, it became a household name almost overnight. Osakabased Okada has pulled off the same feat in the Japanese industry of demolition attachments.
Primary crusher TS-W1100V.
One of its models, IPH400 (pronouced “aiyon” in Japanese) grew so popular that aiyon has become a byword for hydraulic hammers in Japan. “Now, when Japanese contractors need a high-performing hydrohammer they come to us asking for an aiyon,” says Shigeru Hirosaki and Taihei Hosokawa from Okada’s overseas department.
Humble beginning It was back in 1938 when Tatsuo Okada founded Okada Rock Drill Co., a small family venture that manufactured small-size pneumatic hammers and drills for mining and construction applications. The first incarnation of the company was not destined to last, though. Soon Japan was dragged into the maelstrom of World War II, and Tatsuo Okada was forced to close his shop, but when the war finished the Okada family set about reviving the business. They scurried around Osaka on bicycles clutching bags of small pneumatic hammers they touted to customers. By the late 50s, Japan’s war wounds were largely healed, and its economy began to grow. This gave Okada the chance to develop into a fullblown manufacturing enterprise with a solid product line. It was around then that the legendary IPH400 was designed. With power 10 times greater than 30kg class hammers available at the time, it became a hit and spawned generations of aiyons. Following its success, Okada expanded the line with IPH200, 600 and 1000 models to meet customer demand.
Big time The steady growth the company enjoyed since the late 50s culminated in Okada’s listing on the Osaka Stock Exchange in 1992. It enabled Okada to widen its international reach, and to strengthen its position as Japan’s leading manufacturer of demolition attachments. By that time, Okada’s line-up featured not just trademark aiyons, but also all kinds of tools, such as primary crushers, pulverisers, shears, and grapples. In parallel, Okada was active in the recycling business. It became the first Japanese manufacFamous aiyon or hydraulic hammer.

ORC-81V – Okada’s secret weapon in Europe.
turer to implement the mobile crusher concept when it launched the crawler-mounted jaw crusher CR36B/ CR24 in 1994. When the economic boom of the 90s was followed by the stagnation of the 2000s, Okada refused to slow down. Even at the height of the ongoing global recession it kept investing in product development and scouting for new markets. Japan’s economy is still in the doldrums, therefore priorities are shifting towards overseas markets. The Okada brand is already well known in North America and Europe through the efforts of its subsidiary Okada America Inc. and the Netherlands-based liaison office. Since 1995, another Dutch company, ACDE Europe, has been distributing Okada’s products in the Benelux countries and Germany. In 2010 Okada set up a sales office in India.
Okada 2010 The current Okada has 191 employees with an annual turnover of over EUR 60 million. Since 2007, its president has been Toshiyuki Kanda who joined Okada after working for Sumitomo Mitsui Banking Corporation. Okada’s production facilities are based in the prefectures of Aichi and Saitama. The 7,000m2 factory in Aichi produces famous aiyons, while crushers are manufactured at the 4,600m2 plant in Saitama. Okada dominates Japan’s crusher market with a 40% share and commands 20% of the hydraulic hammer segment. According to Shigeru Hirosaki, the domestic market for hydraulic hammers is shrinking amidst a growing campaign to curb noise levels within city limits, thus making way for quieter techniques like crushing. Domestically, Okada has built a strong network of 11 branches, each one having its own service department to provide consulting and after-sales services in every corner of the country.

Pricey but worthy The Okada attachment that currently tops its bestselling list is the 1.5t hydraulic hammer TOP200 and is quite popular with demolition contractors. So far, Okada has sold over 3,000 units worldwide. However, in line with market expectations, Okada is now refocusing on developing crushers, rather than hammers. Okada’s current range includes the TS-W1100V, a 2.4t primary crusher with a jaw opening of 1.1m, and the TS-W2000V boasting a jaw opening of 2m. The jaw is shaped as a sharp wedge to cut through concrete. Triple master TS-WK800V is a versatile demolition attachment applicable for primary crushing, pulverizing and rebar cutting. Jaw tines are designed in a way to allow the material to fall through the jaw for maximum performance. Okada is proud of what it has achieved with the TS-WK800V and recommends it as a universal solution to a wide variety of demolition tasks. Okada’s other trump card in the multi-purpose crusher segment, is the rotating crusher ORC-81V, which has been designed specifically for the European market and currently being tested in the Netherlands. It is capable of completing a full cycle of primary to secondary demolition operations within a much shorter period of time. There is the possibility that Okada may also become a household name for crushers too.

High-cycle wall sawing at its most compact: hurricane SB120 The newest member of the braxx family which was presented at this year’s Bauma, the hurricane SB120, has proven to be the concrete cutter’s darling for flexible use. With its 12 kW nominal performance, despite the compact dimensions, it features cutting depths of up to 430 mm, at only 22.5 kg saw body weight and 350 mm maximum depth.
The handling eases daily work The rail fastening brackets can be set slant for optimal stair cutting. Also, they have higher ground clearance, and the rails can be extended and connected easily with eccentric bolts. Due to the rail design, the saw can be set onto the rail on both sides, so the user can make division cuts without removing the rail. And not to forget, the roller guides makes the saw run smoothly. To round off the advantages of the new EDT Eurodima rail systems: it has the lowest rail weight in the class up to 15 kW. The rail fastening brackets and a demountable flush flange are standard equipment for the hurri-
cane SB120. As braxx users know, the drive motor can be taken off without any tools. Revolution and torque setting is continuously variable, by using a potentiometer. The new hybrid ceramic ball bearing, lubricants that were developed especially for high revolutions and other robust technical details such as high-strength spindles are the reason for the high output per operating time, service intervals are very long.
New braxx control BC120 Together with the hurricane SB120, the new braxx control BC120 is launched. Like the other control units of the braxx family, it features EMV security together with easy operation. The BC120 is especially compact with its trolley-like transport, and its connections and pins are set deep in the frame, so that it provides better protection from potential damage. Easy menu navigation, self-explanatory display with direct and indirect lighting, phase failure detection, line safety switch, remote control etc. are standard for braxx control users.

remote control and its bright LED display. The 32 channels with automatic channel search ensure proper connection, and the robust design, the ergonomic abdominal belt as well as the IP65 specification provide further advantages for users. In addition to the high cycle technology, it
can be used for hydraulic machines by employing a braxx engine. A customer in southern Germany used a new base package of the WM50 with the braxx EB200 engine. The concrete sawing contractor wanted to utilise the wireless remote control with the hydraulics system. The contractor’s operatives were trained by application engineer Harald Drum, together with the customer’s advisor. The combination of WM50 with wireless remote control was a first-time application in Germany. The introduction and training of the employees was completed with ease as they had worked with the WM50 for many years, and the handling of the EB200 and the wireless remote control is easy. The users perceived the wireless remote control as a special highlight, as the operating range was virtually unlimited and no cable was there to hinder operation. The wireless remote control can be used in all high cycle combinations of EDT Eurodima.
US Stone Construction Equipment adds diamond saw blades In the US Stone Construction Equipment Inc has added a diamond saw blade line to complement its range of masonry and concrete saws. The new saw blade line covers the most common sizes for the vast majority of cutting applications. The 26 primarily general purpose blades in the line fall into two categories of Saw-lect, the value line, and Saw-preme the premium line. The laser-welded blades are well balanced and flatter, delivering faster, straighter cuts, the first time, every time. The blades range in size from 305mm to 508mm, with bond ratings from 3 to 8 to cut brick, block, stone, cured concrete, green concrete, asphalt and asphalt over concrete. The blades fit all 25mm arbors and can be used wet or dry. They fit both Stone saw lines, and the majority of the blades can also be used on high-speed saws.

A Viking in On a Glendale back street in the vibrant greater Los Angeles area is the home of the demolition company Viking Demolition Contractors Corporation. Even though recession has struck hard in Los Angeles there is a lot of activity and one suburb after another teams up with only the name badges that distinguish them apart. Los Angeles feels like one big city rich with Mexican culture.
The recession has left clear traces “It may look as if it’s full speed based on the activity of all the people and the heavy traffic, but I assure that you that’s a false impression. You would have seen it a few years ago before the recession crippled everything in this area,” says Berger Jostad who founded Viking Demolition Contractors together with his partner Mike Tredick in 1965. The bad economy in the country, particularly in California has clearly left its mark on everyday life. “We have reached the bottom, but it is a very long way back to reach halfway in relation to how we had it before. The recovery has gone much faster on the East Coast than in the West,” says Berger. Inside the office there are a number of empty desks. Here was a hive of activity only a few years ago and they had a lot of work. In the office now work mainly the brothers Todd and Scott Tredick with Berger Jostad coming in a few days a week. It was Todd and Scott’s father Mike and Berger Jost who started the company in June 1965. Mike is now retired and Berger has also cut down his work in the company as he is 77 years old.
One of the oldest
That the Vikings discovered America is nothing new but did they really go all the way to California? Berger Jostad seems like living proof for that both by appearance and name. And he even runs, together with his colleagues, Viking Demolition Contractors Corporation in Los Angeles. 64 PDi • Issue 4 - 2010 • September - October
The company is one of the oldest operating demolition firms in the United States. The demolition tradition in the US goes much further back then 1965, but the really old companies have either gone bankrupt, reorganized or closed down. So most of the oldest and still active were formed in the 1950s or 1960s. Viking Demolition Contractors is a fairly typical American demolition company. It focuses on traditional heavy duty total demolition. Partial demolition or renovation demolition are less common for Viking. Usually everything in this area is removed and replaced with new. Viking Demolition purchase services in terms of recycling of demolition debris and almost nothing is running on landfill now. “Actually, we have always worked with recycling in the sense that we have tried to resell everything that we considered to be of use. However, we do not deal with the recycling and crushing. These services we buy from local recycling companies,” says Berger. Berger was born and raised in Madison, Wisconsin by Norwegian parents. His mother was also born in the US but both her parents came from Stavanger, while Berger’s father was born and raised in the town of Hardanger, not far from Bergen, on Norway’s west coast.
Heavily influenced by Norway Berger remembers his childhood as strongly marked by
n Hollywood the Norwegian culture both at home and throughout the community where he lived. “I remember when I went to school more than half of the children in the class came from or were related to Norway. There was a lot of Norwegians in the area where I grow up and we all looked like Norwegians,” says Berger. The language at home was Norwegian but gradually English language took over and Berger has forgotten much of the language he spoke as a child. During the great emigration from Scandinavia Swedes sought mainly Minnesota, while the Norwegians in larger numbers stayed in Wisconsin. Although both of these states in terms of latitude are considerably further south than Sweden and Norway they still have rather harsh winters with a lot of snow and several degrees below zero. Berger wanted to go to the south of the country and after completing training in economics at the University of Wisconsin, he moved to California because of his military service in the US Air force. When military service was over he remained in California. His colleague, Mike Tredick, Berger met many years ago. Berger got a job as a salesman at the same company where Mike was working and after a few years they decided to start a construction business together. The reasons were many but the area around Los Angeles expanded considerably and there were a lot of work. At that time, San Fernando Valley looked completely different. By then, communities as Glendale, Burbank, Van Nuys, Reseda, Tarzana and others were separated by large green areas. “At the time there were a lot of orange plantations in the San Fernando Valley. The whole valley was full of orange groves and in the first years we worked very much in clearing the orange trees. Plantations were replaced by buildings and other things as the area was exploited, ” says Berger. It was the time of the Freeway and along the new roads the suburbs where expanding rapidly. Berger and Mike’s company was frequently hired to clear away for road construction and others. But over time the company grew and the duties changed towards demolition services. The orders came increasingly from the major studios that have their recording studios in the area. Viking Demolition Contractors have done many demolition projects for companies like Universal Studios, Warner Brothers, Paramount Pictures, Walt Disney Productions to name a few. The assignments may involve tearing down an old so-called set to make way

The birth of the new construction equipment association in Italy, UNACEA A new association of construction equipment and attachment companies, called Unacea, has been formed in Italy by a group of Italian manufacturers Fiori, Ihimer, Indeco, Simex, together with two of the world leaders in the sector Komatsu Utility Europe, and New Holland Kobelco, which have their primary plants in Italy. The board of Unacea has been formed by the founding members, who elected Enrico Santini from Fiori as president for the necessary period to acquire new associates and before a assembly of the members is called. Franco Invernizzi from New Holland Kobelco and Enrico Prandini from Komatsu Utility Europe have been appointed vice-presidents. Luca Nutarelli has been called to hold the general secretariat. Unacea already represents 50% of the turnover of the earthmoving equipment sector in Italy. “Italy’s earthmoving machinery industry is number one in Europe,” said Enrico Santini. “And, in spite of the crisis, the Italian market is still one of the most important of the Union. Up to now, however, our division did not have a trade representation able to grow and to deal with the problems of the sector in an autonomous manner. This is why, after fruitless efforts to have their needs understood, a number of companies have left Unacoma/ Comamoter and have now undertaken this challenging project: to build a trade association which is firmly in the hands of the sector companies. We need an association that fights to emphasize product quality against the unfair competition of countries that do not respect EU directives, and to create limitations to the use of obsolete machinery, which is detrimental to all citizens and to our industries, thus obliged to pay all the costs to adjust to increasingly pressing European regulations. Only with an association run by the companies themselves and able to join together the whole sector can the Italian industry aspire to attain a leading role at European level.”
EPA’s new Lead Safe Rules The US Environmental Protection Agency’s recently enacted Renovation, Repair and Painting Rule for contractors, informally know as the lead safe rule, may appear complex and difficult to follow. But these more stringent regulations on

handling lead paint should prove to be a boon for both homeowners and contractors, according to LeadSafe Video Solutions Inc president Chris Zorzy. According to Zorzy, under the new EPA guidelines, contractors must use lead safe work practices and follow procedures that contain the work area, minimize dust, and clean up thoroughly. Any lead paint must be removed using approved methods, and all debris must be contained and disposed of using appropriate precautions. “To become lead safe certified, a company must undergo an 8-hour training programme from an EPA-approved trainer, then apply for and receive a Lead-Safe Certificate. Until that happens you cannot begin work on a home or building erected prior to 1978, when strict lead paint laws were passed,” says Chris Zorzy, whose company, LeadSafe Video Solutions, provides training for contractors’ employees and staff.
CSDA Releases Three Best Practice Documents The US Concrete Sawing & Drilling Association announces the release of three new Best Practice documents entitled Polished Concrete Floors (CSDA-BP-008), Green Construction (CSDA-BP-009) and Hi-Cycle Concrete Cutting Equipment (CSDA-BP-010). The release of these three documents brings the Association’s series of Standards, Specifications, Tolerances and Best Practices to 27 in total. Produced by CSDA’s Standards and Specifications Committee, these latest Best Practices cover three very different, but equally important, subjects to cutting professionals. The method of preparing and polishing concrete floors continues to be popular in industrial, commercial and residential areas, and many cutting contractors are adding this technique to their range of services. A CSDA Best Practice has been released on this subject to promote the benefits of polished concrete floors and, more importantly, to aid sawing and drilling professionals
PDi • Issue 4 - 2010 • September - October
who wish to offer this service to their customers. This document complements a Specification (CSDA-PC-113) released on the same subject in 2008 by the Association. An increasing number of companies are recycling on the job site and in the office to be both environmentally-friendly and cost-effective. The Green Construction Best Practice is specific to the sawing and drilling industry, and provides insight and guidance in the creation of a site-specific plan for environmentally-friendly work practices to be performed by sawing and drilling operators. It also provides tips and suggestions for making a shop or office more “green.” CSDA-BP-010 focuses on the application of hi-cycle cutting equipment. There is increasing pressure from general contractors and government municipalities for cutting contractors to provide alternatives to hydraulic equipment, so the increased availability and serviceability of hi-cycle/ high frequency systems is helping many contractors make the switch. The Best Practice provides detailed information on hi-cycle equipment and cutting methods; including power, available systems and a list of common terms and definitions to educate contractors.
CSDA Resource Guide Aids Specifiers Architects, engineers, general contractors and government officials, virtually everyone who is involved in specifying sawing and drilling services in their daily work, have 24/7 access to the US Concrete Sawing and Drilling Association’s, 201011 Resource Guide. CSDA offers this guide as a printed manual, but the guide is also available free of charge online at www.csda.org. “The mission of the Concrete Sawing and Drilling Association is to promote sawing and drilling services and the contractors that perform these services to specifiers, highlighting the advantages of their use in renovation or demolition projects,” said association executive director Patrick O’Brien. “To have these resources available in print and on the Internet helps specifiers access this information whenever and wherever they need it.” Diamond cutting systems can provide significant cost advantages over conventional removal methods, yet many architects, engineers, general contractors and government officials are not aware of these cutting techniques and capabilities. Whether it is a major infrastructure project such as a power plant or dam renovation, or a highway or airport surface repair job, cutting and removing large sections of concrete can be much more cost effective than other demolition methods. Diamond cutting systems can also help maintain the structural integrity of surrounding structures due to minimal vibration and less debris. The latest CSDA Resource Guide contains a comprehensive collection of 24 specifier resource documents produced by CSDA in conjunction with the Occupational Safety and Health Administration and the International
Association of Concrete Drillers and Sawers. Specifications, Standards, Tolerances and Best Practice documents included in the guide can help specifiers better understand the wide range of cutting capabilities that exist through concrete cutting, and provide ideas on how the use of diamond cutting tools can be advantageous in future projects. The Resource Guide is just one of the tools that CSDA provides for specifiers. The Specifier’s Corner of the CSDA Website home page includes a feature to submit project details and request bids from CSDA contractors through the completion of a simple online form. This area of the website also contains PDF versions of individual Standards, Specifications, Tolerances and Best Practices. In addition, each sawing and drilling job story published in Concrete Openings magazine can be downloaded for reference from the Techniques page of www.concreteopenings.com, where they are arranged by the technique used. Specifiers are encouraged to utilize the Resource Guide and other tools offered by CSDA.

CSDA/OSHA Alliance Releases Toolbox Safety Talk The Alliance between the US CSDA and the Occupational Safety and Health Administration has released a Toolbox Safety Talk entitled Sprains and Strains Prevention (CSDA-OTST-1001), the fifth document produced by the Alliance. “Working in an industry where employees can be required to lift or carry large objects, whether it is pieces of debris or items of equipment, workers need to know what are the best ways to handle objects without inflicting injury upon themselves or others,” says CSDA Past President Tom Stowell, who created the document. “Injuries caused by improper lifting techniques not only have an impact on a person’s work, but their lives as a whole,” Stowell added. “That is why this Toolbox Safety Talk is so important.” Sprains and strains account for about one third of injuries in the construction industry and, depending on the severity of the injury, can be simply an overstretch of a muscle or ligament that can result in a partial or complete tear. An injury like this can often hinder, and sometimes end, a worker’s career. This Toolbox Safety Talk provides details of safe working practices to reduce the likelihood of sprains and strains, and identifies common mistakes when moving objects in the workplace. The Alliance Toolbox Safety Talk on the prevention of sprains and strains follows the release of four Best Practice documents on the subjects of Highway Work Zone Safety, Reducing Silica Exposure, Defensive Driving and Electrical Safety. Three of these Best Practices are also available in Spanish on the CSDA Website.
