New dumpers from AUSAIn response to customer demand, Spanish construction equipment manufacturer AUSA has recently launched two new 2.5t articulated rotating dumpers, the D 250 AHGA and the D 250 AHG, which complete its line of dumpers. The dumpers have been designed specially for the Central Eu-ropean and Scandinavian markets, where there is
BICES and AEM Join Forces The Beijing International Construction Machinery Exhibition and Seminar and the Association of Equipment Manufacturers, which owns the CONEXPO Asia exhibition, have announced a cooperative effort to ensure the perpetuation of an international construction machinery exhibition in China. The BICES-AEM partnership will bring together manufacturers, customers and industry organizations to produce the most successful event possible for all industry stakeholders. BICES 2009 will be held 3-6, November 2009 in Beijing at the Jiuhua International Exhibition Centre.
Atlas Copco with-draws from IntermatAtlas Copco together with Dynapac has withdrawn from participating at the construction trade show Intermat 2009, which will take place in Paris, France in April 2009. A trade show like Intermat requires extensive resources to attend, both in terms of money and people. Because of the turmoil and uncertainty in the construction mar-ket, fewer visitors, particularly international, are expected to come to Intermat. With this in mind, Atlas Copco estimates it can bring more benefits to customers by reallocating the effort spent on Inter-mat and focusing on more targeted activities. Atlas Copco is committed to the construction market. The company says that it will also in this downturn develop the leadership by working closely to the customers. By focusing on more direct customer activities, they will interact more efficiently with the customers and will be better able to respond to the direct needs of the market.
Bobcat’s 50th Anniversary Competition WinnersBobcat has announced the three prize-winners in the ‘What Did Bobcat Do For Me?’ 50th an-niversary celebratory competition. The winner of the Grand Prize, a trip to the USA, including a visit to the Bobcat factories at Bismarck and Gwinner in North Dakota and a one-day visit to New York, was David Arthon of Fuveau in Aix-en-Provence in Southern France, a customer of the Bobcat dealer Boïs. The second prize, a EUR 1000 voucher for Bobcat products, went to Richard Heskens of the Netherlands, a customer of Bobcat Zoeterwoude. Mathias Morlion of Belgium, a customer of Bobcat dealer, Vangaever, won the third prize of a EUR 500 voucher for Bobcat products.

Hillhead 2009 PostponedIn view of both the scale and speed with which the current adverse economic climate has developed, a decision has been made to postpone the UK show Hillhead scheduled for June 2009 for a period of 12 months. Despite the show being heavily booked as usual, discussions took place with leading exhibitors at the end of January following which it was concluded that it would be in the best interests of the event if it were put back a full year to allow UK market conditions time to stabilise. The organisers apologise for any inconvenience this may cause and the new dates for Hillhead 2010 are 22-24 June.

Stone adds diamond saw bladesThe US company Stone Construction Equipment, Inc has added a line of diamond saw blades 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 appli-cations. The 26 primarily general purpose blades in the line fall into two categories, Saw-lect the value line, and Saw-preme the premium line.
The laser welded blades are extremely 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 con-crete, asphalt and asphalt over concrete. The blades fit all 25mm arbours 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.

Where music and demolition met, for one last time…The iconic Astoria music venue in the heart of Lon-don’s theatre land has played host to some of the biggest bands in the music business. In its 30-year history, the Astoria’s 2,000 capacity venue played host to everyone from the Beach Boys and David Bowie to current stars such as Amy Winehouse, Oasis and the Arctic Monkeys.
But as preparation for London’s Crossrail project gathers pace, the venue hosted its last-ever gig. Even as concert goers were queuing, amid TV and radio journalists capturing the moment for posterity, scaffolding was being put in place to facilitate the demolition works. Bizarrely, in the middle of all this, a music journalist for BBC Radio, who was there to see the demolition, was
interviewing PDi’s Mark Anthony, who was there purely to watch the bands.

Primarily customer of TRAXX will be a consumer of goods involved in the concrete sawing and drilling, rental, demolition, concrete placement, construction, tiling, surface preparation and stone processing indus-tries. TRAXX manufactures many of its own products but reserves the right to source the very latest and innovative additions to the construction industry, from a vast network of business partners. The people behind Traxx are Lloyd Williams, Gail Williams, Dianne Eade, Lorraine Kenny, Stuart Smith and Mark Snoad. More about Traxx in the next issue of PDi.
Atlas Copco’s new business structure for the USAAtlas Copco Construction Equipment LLC is the name of the new Atlas Copco business dedicated to serving the US construction market. This new entity combines the Portable Air operations of Atlas Copco Compressor Technique’s US sales company with the Atlas Copco Construction Tools US sales company. Atlas Copco Construction Equipment is responsible for the sales and service of portable compressors, generators, pneumatic, hydraulic and gasoline-powered construction and demolition tools, along with related aftermarket services, for both the Atlas Copco and Chicago Pneumatic brands.
The new organization is based in Commerce City, Colorado, sharing offices and back office functions with the Atlas Copco Construction Min-ing Technique USA customer centre. Although the two companies will operate independently, they have much the same culture and market knowledge and can benefit from these and other synergies. The Westfield, Massachusetts office of the Construction Tools business will be closed at the end of March 2009.
Top priorities of Atlas Copco Construction Equipment LLC are to stabilize the sales and service structure, to support customers, and to continue to be a leader in the construction equip-ment business. The new company will have three sales and service regions in the North, South and West United States.
Erik Sparby heads up Atlas Copco Construc-tion Equipment as its general manager. “We are looking at this as an opportunity to become more focused and dedicated, specializing on the unique needs of the construction industry,” he said.

Five years of finding concrete solutionsDiamonds have come up trumps for the Austra-lian company Kennards Concrete Care, which celebrated its fifth anniversary in January this year. Since 2004, the specialist equipment hire company has helped hundreds of contractors

tackle all sorts of concrete related jobs, from demolition, drilling and cutting to grinding, strip-ping and planing.
Starting with a hire centre in Sydney, Kennards Concrete Care quickly added outlets in Brisbane, Melbourne and Perth. Growth has come not just from the array of equipment on offer, but from the expertise of staff, who can advise customers on the right machine or the right diamond for their job.
Kennards Concrete Care was the idea of Angus Kennard, whose grandfather, Walter, founded Kennards Hire in 1948. While working in the general hire business, Angus developed an interest in concrete equipment, and began adding more products at the branches he managed. He believed there was a need that was not being fully met, and after travelling overseas to learn more, launched Kennards Concrete Care as a stand-alone entity. “Our business is about providing solutions to problems,” said Angus. “Rather than a customer coming in and saying, ‘I want a grinder,’ he is more likely to say, ‘I have this situation, what have you got that will do the job?’
“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. When you are working with concrete, there are many variables and job limitations that have
to be considered. With surface preparation, there is the hardness of the concrete, the product to be removed, surface finish required, whether it is inside or outside, is it a wet or dry environment, is there a need for dust control and what power source, if any, is available. We have grown largely because satisfied customers come back, more people are finding us through our website and our product range continues to expand.”

JCB’s new £40 million factoryIn the UK the curtain has fallen on almost 140 years of manufacturing history in Uttoxeter as the final machine to be made at JCB’s Heavy
Products factory rolled off the production line. The manufacture of tracked and wheeled excavators is being transferred to the new purpose-built £40 million JCB Heavy Products factory in Uttoxeter.
“This is the end of an era because my family has been linked to this site since the nineteenth century when Bamfords Ltd started manufacturing agricultural machinery,” said JCB Chairman Sir Anthony Bamford. “But this is also the start of a new and exciting era, not only for JCB’s excavator business, but also for Uttoxeter because the relocation offers the op-portunity to redevelop and enhance an important area of the town.”
Sir Anthony’s great-grandfather Joseph Bamford was one of five brothers who were the original partners of Bamfords Ltd. Sir Anthony’s
own father, the late Joseph Cyril Bamford, was famously sacked from Bamfords Ltd by his uncle Henry. Joseph Cyril Bamford later went on to found JCB, which has grown into one of the world’s most successful construction equipment manufacturers.
The move to the new JCB Heavy Products factory represents an opportunity for JCB to grow its tracked and wheeled excavator business once the global construction markets recover from the current downturn. The company’s excavator range comprises machines from 7t to 46t.

Bobcat launches first wheeled excavator Bobcat has launched its first wheeled excavator the 5.5 t E55W powered by a 40.8 kW Yanmar liquid-cooled diesel engine. Equipped as standard with single tyre configuration, dual tyres are available as an option. The E55W offers 2 travel speed ranges, with a maximum travel speed of 30km/h. The maximum digging depth is 3.495m, the maximum dump height is 4.265m and the maximum reach at ground level is 5.89m.
The undercarriage consists of a rigid, welded frame. The routing of hydraulic lines, protection for the transmission and heavy-duty axles make the undercarriage ideal for wheeled excavator applica-tions. Both the outriggers and dozer blade are pin type for maximum flexibility.
The operator cab offers the same space as that found in the cabs on much larger medium and heavy-duty machines. The steering wheel can be positioned to suit the operator and the position and angle of the seat cushion as well as the position
of the consoles can be adjusted independently of each other. The operating controls have been arranged to ensure convenience and comfort. The hydraulic joystick levers have grips that allow the operator to perform precise operations easily.
In addition to the normal trenching and groundwork jobs, the E55W’s stability and lifting capacity allow the excavator to be used for ap-plications such as truck loading and unloading and moving pipes and materials. For maximum safety during all operations involving lifting work, the E55W is equipped with an overload warning device as well as safety valves in the boom and dozer blade hydraulic systems.

The new Allu SCH screener crusher can handle various kinds of demoli-tion waste effectively like bricks in this case.
The first crushing buckets for full-scale use in demolition and recycling applications were launched at the end of the 1990s. Their forerunners, to simplify demolition and recycling, were the hydraulic crushers and pulverisers. Today these attachments complement each other and have made the demolition and recycling process so much easier. The Finnish manufacturer Allu launched its first screening crusher in 1991 for crushing lighter demolition waste.
Compact and flexible recycling on site
The bucket crusher is a hydraulic tool, developed from traditional jaw crusher technology. Although unlike a conventional crusher, a bucket crusher is operated by hydraulic power provided by the excavator it is attached to. The bucket makes it possible to pick up the rock to be crushed and then to load into trucks or use as back filling on site. The reduction in outlay costs is clear because this system makes it possible to reuse inert materials without having to take them to a landfill, while the ability to crush different types of materials makes it possible to use them directly on site.
The areas of application of these tools are numerous and include demolition, building construction, earthmov-ing, excavation, road works, quarrying and mining, land reclamation and trenching and rock breaking or crushing of quarry material.
Upgraded model from Trevi Benne
The Italian manufacturer Trevi Benne is now strengthen its position as supplier of crushing buckets by introducing an upgrade version of their crushing bucket series BM. The Crusher Bucket BM Series is available in two different models. The BM 25 weighs 2.5t and BM 35 3.5 t. They
are designed for crushing inert materials from demolitions and building renovations such as concrete, asphalt, waste material from storage centres and debris in quarries, to provide a finished product for use as backfill.
The Crusher Bucket allows on the spot recycling of waste material for immediate reuse on the site. The power is produced from the eccentricity of the pounding unit for crushing the material in the bucket. The interchange-able plate system reduces maintenance costs and limits downtime.

Allu a truly global playerThere are just a few manufacturers of crushing buckets with global sales. One of the companies is Allu Finland Ltd, which was founded in 1985 by Markku Jonninen. The company was first called Ideachip Ltd, but it changed its name to Allu Finland Ltd in 2007. The new name stems from the company’s globally recognised trademark Allu. Allu Finland Ltd created the Screener Crusher method in 1991. To date, their sales constitute over 80% of the world market for Screener Crushers.
Last year Allu released their Allu SCH Screener Crusher for heavy applications. Allu SCH Heavy series are suitable for 20–34t excavators and 12–24t wheel load-ers. In this series, the frame is reinforced and the engine is a heavy-duty model. The maximum driving output of

MB first with the Bucket CrusherAnother manufacturer that has proven to be a world-class supplier of crushing buckets for heavy use in demolition and recycling applications is the Italian company Meccanica Breganzese. MB has specialised in construction and sales of jaw-action bucket crushers and manufactures four basic models. These are BF 60.1, the smallest in the range, suitable for excavators in the 8-14t class, BF 70.2 for excavators from 14-20t, BF 90.3 for excavators from 20-28t, and the largest model, BF 120.4, for excavators weighing more than 28t. According to MB they produced the world’s very first bucket crusher. By using an MB crusher the crushed material can be recycled directly on site resulting in a significant reduction of costs. The equipment is versatile and all that is needed is a standard excavator in order to work efficiently.
The benefits with the MB crushers are the facility to crush any type of material insitu and in any type of situa-tion, with a significant reduction of operating costs. Thanks to their production capacity, MB bucket crushers can be utilised in small, medium-sized and large worksites, thus dispensing with both plant hire and transport costs. The bucket crushing solution eliminates the problem of waste disposal. Product output can be received in the required size just like a standard crusher.
MB’s models
The smallest BF60.1 in the range weighs 1.5t and is rec-ommended for excavators in the 8-12t class. Crusher jaw opening is 600 x 450 mm and bucket capacity is 0.5m3. The material size is adjustable between 20 and 100mm, while average hourly production is between 9.1 and 19.8 m3, depending on the required product size.
The second smallest model, BF 70.2, weighs 2.25t and
is recommended for excavators weighing between 14 and 20t. Crusher jaw opening is 700 x 550 mm and bucket capacity is 0.6m3. The output size is adjustable between 20 and 120mm, with average hourly output of between 12 and 30m3, depending on the required product size.
The first bucket crusher to be manufactured and marketed was the Bf 90.3 weighing 3.5t and recom-mended for excavators of 20-28t. Crusher jaw opening is 900 x 450mm and bucket capacity is 0.75m3. The output size is adjustable from 20 to 120mm, with average hourly output of between 18 and 40m3, depending on the required product size.
The largest bucket in the range is BF 120.4. It weighs 4.9t and recommended for excavators from 28t. Crusher jaw opening is 1200 x 450mm and bucket capacity is 1m3. The output size is adjustable between 20 and 120mm with average hourly output between 25 and 50m3, de-pending on the required product size.
MB has also an iron separator system that was unveiled at the end of 2007 at the SAIE trade fair in Bologna. Available for all MB bucket crusher models, this device is composed of a 250kg magnet, a magnet support, and an installation kit. The device is easy to install on the bucket and allows the separation of ferrous materials from inert material to be crushed.

VTN Europe - Three different seriesThe Italian manufacturer VTN Europe is manufacturing three series of crushing and screening equipment, the SB, FB and SR series. The SB Series is commonly used for screen-ing demolition material and quarry residues. The material is screened using the innovative vibrating and alternating movement of the screens fitted longitudinally inside the bucket. Thanks to the vast range of screen sizes available and their interchangeability, the same model of bucket can be used to screen materials of different sizes.
The heavier FB series is a full size crushing bucket, which has been designed and built to meet the increasing necessity for immediate on-site recycling and reuse of waste material deriving from construction and demolition work. The high performance levels of the FB crushing bucket, available in two models, make it the ideal solution, not only for small and medium-sized construction sites with limited amounts of waste material, but also for extremely demanding work conditions, such as quarries. It is made entirely of Hardox 400 and equipped with a fixed and a moving jaw. The adjustment of the moving jaw allows the size of the crushed material to be adapted to the different operating needs.
VTN also produce a rotary screening bucket called SR. The SR series is made in five models for use on excavators with capacities ranging from 7-35t and has widespread ap-plication in screening natural material, such as river beds, quarry residues, sand and dry soil, as well as all situations where fine screening is required.

The CB-line from SimexSimex has expanded its operations into producing crushing buckets, which were shown for the first time at the exhibi-tion SAIE in 2006. The new Simex CB line of crushing buckets, contain nine different models in sizes from 1.4 to 2.4m in width, bucket weights from 800 to 3500kg and crushing sizes of the material from 10 to 80mm. They are suitable for use on wheel loaders and skid steers. What makes the Simex crushing buckets different from other brands is the rotating function instead of jaw crushing. As in all other Simex products the main details and the functions are patented. The body of the teeth in the rotating crushing unit is made of Hardox.

The 2009 edition of the US construction industry’s premier annual trade show saw a 23% drop in attendance from last year, with most of the blame directed at the global economic upheaval that has slowed or halted building activity in nearly every market sector.
The decision-makers cameBut although the 65,287 who attended WOC may not match previous shows, they were, for the most part, the people that the concrete cutting, demolition and floor prep industry vendors wanted to see. “These are the decision-makers, the people who have needs and are ready to buy,” observed Greg Smith of Allied Construction Products, which was showing its TotalBreakerBits line of replacement tools for hydraulic hammers. Smith added that while many organizations may have been unable to afford dispatching large contingents to Las Vegas, industry vendors couldn’t afford to stay away. “It’s important to be here and be noticed regardless of the turnout,” he said. “If you’re invisible or pull back, no one will remember you when they are in position to buy new equipment.”
Many exhibitors chose a more austere approach to telling their stories, even though exhibition space was only 2% off 2008’s total. “The one-upmanship among vendors isn’t here, something that is probably long overdue,” said Stihl sales representative Hugh Munn.
And while vendors may have come to WOC 2009 with lowered expectations, a hopeful worker at Stanley Tools aptly observed that, “we just need that one visitor to make it all worthwhile.”
A field day for concrete floorsWOC’s attendance may have been down, but the proportion of concrete floor grinding and preparation equipment was sub-stantially higher. Among the many products vying for attendees’ attention were DITEQ’s 762mm and 660mm planetary floor preparation and polishing system, SASE Company’s EDGE
Pro 180 variable-speed edger with pivoting wheels, Terrco, Inc.’s direct-drive edger with adjustable depth-setting rollers, and HTC’s dual-head 1500 ixT ride-on grinder.
Blastrac continued to boost the profile of its US built Diamatic line with products such as the 584mm BMGP 600-R grinder, which uses the company’s point of development technology to col-lect dust and debris through the machine, resulting in a cleaner work path and cooler diamond and polishing heads. “POD offers benefits on many different levels, such as cleaner, healthier work environments, longer tool life and reduced labour and equipment costs,” says Blastrac spokesman Jason Root.
The proliferation of floor preparation and pol-ishing equipment comes as no surprise to ON-FLOOR Technologies, Tom Francis.
“It’s all part of the industry’s current green consciousness,” said ON-FLOOR Technologies
World of Concrete vendors and atten-dees keep a brave face despite uncertain times. Much the way celebrities and ave-rage citizens alike have used Las Vegas as a springboard for reinventing them-selves, WOC may want to consider adopting a new slogan: size isn’t everything.
representative Tom Francis. “On 90% of industrial floors, the surfaces are man made and will ultimately end up in landfills. Polished concrete floors eliminate the need for chemicals to clean crevasses and improve reflectivity, which cuts energy costs, improves employee health, and makes for a brighter, more invit-ing environment.”
Concrete polishing also presents opportunities to apply alternative energy sources, such as propane, which powers Eagle Solutions’ EnviroPro WA27 burnisher, and Concrete Polishing Technologies’ 27-hp aluminium-bodied G320 PRO grinder.
CPT vice president Dave Padgett said that although a lot of companies are jumping into the surface preparation market, the ones who will make it are more in touch with needs of contrac-tor and their customers’ market trends. They are also the ones who know how to provide smaller contractors with technical support.
Greater awareness of risks with dustMore grinding of floors and other surface types also means more dust to control. Dust Collection Products president John Buser said that awareness across the industry of silicosis and associated health risks is growing, albeit slowly. “Many contractors just don’t realize that silicosis has cumulative effects, and that they need to be consistent about protective measures,” said Buser. “OSHA’s involvement has put pressure on contractors to take action, and we’re gradually seeing more interest in things that will help.”
Dust control solutions on display at WOC ranged from KHK Diamond Products’ polycrystalline diamond blades for reducing material to larger chunks, to Dustless Technology’s ToolSynch mechanism for remotely operating its vacuums, providing con-venience and energy savings as well as improved productivity. Dust Control Technology also featured its new DustBoss DB-45 mid-range sprayer, which can control dust and odour particulates
across an area of 1,115m2.Metabo Corporation executive vice
president Dave Smith said that contractors should also be thinking about protecting their workers from excess vibration from grinders, hammers, and other equipment. “Though not yet a major concern in the US, it is very big in Europe where EU regulations are already in place,” says Smith. “But contractors will soon have

to study vibration data on equipment to determine how long workers can safely use equipment.”
Several products at WOC emphasized their vibration con-trol qualities. Metabo’s new WEO-125 125mm angle grinder has electronic speed stabilization and auto balance features that minimize user fatigue, while Hilti’s new TE60 Combihammer features a built-in mass damper system that produces only a third of the vibration of the company’s TE70, but delivers 15% more performance.
Saws in the spotlightThe cutting side of concrete work also figured prominently at the show. ICS Blount, Inc., announced the beginning of full production of its FORCE4 diamond chain, which has 50% more tensile strength to deliver more power with less risk of breakage. ICS marketing director Ed Hanson explained that its expanded manufacturing facilities for the FORCE4 line will not only provide a price point below its PRO series chains, but also
allows the company to offer an expanded product line with five bar lengths from 250mm to 635mm, and new chain options to handle a wider range of materials.
FORCE4 is also the foundation for a new track-mounted hydraulic wall saw that ICS plans to introduce to the rental mar-ket later this year. “This concept has been around for 10 years, but FORCE4 made it possible,” says Hanson. “It’s particularly helpful for production openings in limited access areas, and eliminates a lot of hassles and conflicts for contractors.”
Also touting wall saw expertise was Husqvarna, which demonstrated its WS440 HF with a water-cooled 400-hz electric motor that generates up to 17 hp. Husqvarna also launched a new dust suppression system that uses a minimum of water mist and is developed to be used among other together with their series of hand held electric power cutters. More about this novelty in the next issue of PDi.
In Diamond B’s booth it was crowded as usual with con-crete cutters waiting for a test drive of the latest from the Pen-truder line of high frequency wallsaws, wiresaws and core drills. Tractive, the manufacturer of the Pentruder series announced introduction of a new wall saw, a completely new core drilling system and a new contact system that will simplify the work.

Another high-cycle cutting option on display was Sanders Saws’ new lightweight BRAXX 1,000-hz wall saw system that supports both wire and blade sawing operations. “At 43hp, the BRAXX can handle up to 1.5m diameter blades,” said spokes-man Mike Horan. “The wire saw version features a number of add-on components for extra versatility that take advantage of high-cycle’s improved dependability.”
Also anticipating a spike in demand for alternative power cutting was MK Diamond Products with the introduction of its MK-4000 and MK-3000 series self-propelled saws that utilize three-phase totally enclosed fan-cooled motors. The 30 hp MK-4000B series provides 89Nm of torque at the blade shaft while the 20 hp MK-3000B series provides 69Nm. MK Diamond vice president and general manager Brian Delahut said that the new products meet the US Environmental Protection Agency’s Tier 3 emissions standards, which may be a requirement for contractors seeking infrastructure work funded by the recently enacted stimulus programme. “If they have a lot of old saws, they’ll need to replace them with compliant equipment,” says Delahut. “We expect there’ll be high demand in the rental market for these kinds of products.”
The pursuit of productivityOne quality never in short supply at WOC is innovation. For example, Genesis Attachments displayed its new GDR 200 demolition recycler. Designed to work with 20t class machines, the fully rotatable recycler delivers 115t of crushing power and features three jaw set configurations. “We drew on a lot of contractor input and ideas to make an attachment that is light, powerful, and inexpensive,” said Genesis southwest regional manager Blaine Archibald.
For all-in-one core drilling, Diamond Products presented its Ultimate Drilling Machine; a self-contained mobile unit for electric and hydraulic powered drilling of 100mm to 610mm diameter cores through asphalt and concrete up to 300mm thick. Attendees exploring remotely controlled demolition options evaluated Husqvarna’s 29.5-hp DXR 310 robot, scheduled to
make its US debut later this year. The DXR 310 was introduced on the European market during the fall of 2008. Brokk’s brand new 260 robot with its 1,900Nm hammer and 7m reach (see article on page 20) were shown for the first time ever at the Las Vegas show. In door the manufacturer also showed another novelty, their largest machine Brokk 400.

dors from the economic uncertainty awaiting them back home. Metabo’s Smith noted that the outlook had seemed even bleaker at the 2002 show in New Orleans, which took place just five months after the 9/11 attacks. This time, it’s a matter of the business cycle needing some upward traction. “Until consumer spending increases and credit loosens, we can’t say what will happen,” said Smith.
Dixie Diamond Manufacturing’s Greg Wolters added that many people were pinning their hopes on President Obama’s stimulus programme, which was still being formulated during the show. “I’m not sure how it will turn out, but at this point, any kind of stimulus will be good,” said Wolters.
Any respite from the string of bad news was welcome, accord-ing to CS Unitec president Tom Car-roll. “People here are talking about business and doing business,” said Car-roll. “They are look-ing for equipment, and new ways to do things. That’s what shows like this are all about.”www.worldof-concrete.com

New Brokk launched at World of Concrete
The design might not be the same as the forerunner but in terms of capacity the Brokk 260 has been de-veloped to take up where Brokk 250 finished. “Since Brokk 250 went out of production in 2000 we have often heard our clients speaking about it with great admiration. So during the past couple of years time we have developed a new and better version of Brokk 250 which we call Brokk 260,” says Brokk President Per Waldemarson when PDi met him at World of Concrete.
A Brokk 250 with modern techniquesBrokk had previously shown the new Brokk 260 as a sort of appetiser at the Scandinavian show, Building Machinery, in early January. The reaction from the industry has been very encouraging, even though there have been few opportunities to test it. Since the international launch at WOC a number of machines have been sold in Europe and the New York demolition contractor Robo Breaking, known to be a big supporter and specialist in operating the former Brokk 250, has tested the first machine in the US.
Brokk 260 completes the machine pro-gramme. It is similar in weight and size to the Brokk 250, but Brokk 260 is also a lot different from its forerun-ner, especially with the new technical solutions it is equipped with. This is an all-round machine in which Brokk has optimized power, capacity and size for use in precise demolition of buildings and for demolition jobs within the concrete and process industry. Brokk 260 is based on the vast Brokk knowl-edge, but is at the same time built for new construction solutions. “Brokk 260 is a machine that is built for use in even tougher environments then its forerunner. A huge amount of effort has been made to design a well balanced machine that is stable during operation as well as transportation,” says Brokk Technical Manager Gunnar Bystedt. The machine weighs only 3050 kg and has a reach of 5.8m. Equipped with Atlas Copco´s new hydraulic breaker SB 302 the machine and the
breaker establish a powerful combination. “Our favourite machine is back!”
A wide range of performance and quality tests has preceded the launch of the Brokk 260. The test work
has included a range of field trials by Brokk´s designers and also by
external well experienced opera-tors. The Swedish demolishing
company Rivners AB was given the opportunity to test the machine on a large job in Stockholm. A satisfied project man-ager, Kent Winborg, says “Finally our favourite size
of Brokk machine is back. We are very impressed by
its large capacity combined with flexibility and efficiency.” Production of the Brokk 260
has started and the first units were delivered in March.

Last year saw the release of several new core drilling systems, but with the current economic crisis there are many core drilling systems on suppliers’ shelves waiting to be purchased. This lack of demand has possibly delayed the release of new models, but maybe later in the year there will be some new products on the market. However, with the next Bauma construction equipment show scheduled for spring 2010, manufacturers may decide to wait for the exhibition to introduce new products.
News from Tractive and Atlas Copco
But there are indications of some activity, as PDi understands that Tractive is developing a new Pentruder high frequency core drilling system. The new system is expected to be officially an-nounced during the second half of 2009 and will be based on a completely new principle.
Manufacturer Atlas Copco is launching their handheld hydraulic core drilling system LCD. Although hydraulic equip-ment may no longer be that popular among professional concrete cutters, there are still applications where hydraulic devices still work.
Operational safety, high performance and long life have been the main targets for the designers of Atlas Copco’s two relaunched handheld hydraulic core drills. At hydraulic torque control reduces kickback to a low level and operators will always be in control, even when drilling holes of 200mm diameter. For operator comfort, the Atlas Copco core drills have low or nearly no vibration and the core drill fits in standard drill stands, whenever the space conditions allow.
The power-to-weight ratio is optimized compared to the previous range. “The surprisingly lightweight core drills convince any customer after drilling the first large hole,” says motor drills, breakers and handheld hydraulics product line manager Jan Byrresen. “Customers comment that they had not believed that this is possible by hand drilling and so safe and fast. The LCD 500 and LCD 1500 is a useful core drill for any job where quick and safe operation is needed in often difficult to access, wet and muddy work sites.”
The drills offer spark free operations since there are no elec-trical components. There is continuous lubrication and cooling through the power pack. Lifetime of power pack and core drill are protected through the closed hydraulic system, which prevents dust or slurry entering the internal parts.
Handheld hydraulic core drills are universal tools for all hand drilling jobs, even in confined spaces, where there is no room for drill stands. Core drills are used in a wide range of applications, including building renovation and utility works.
Core Drills
Recent introductions
Last year Hilti launched their compact drilling system DD120 that can take core bits with diameters between 37-120mm. Hilti has received a lot of credit for their line of professional drill systems and the range contains five electric models and one hydraulic.
Also last year Husqvarna launched their DM 330, which weighing only 13kg, features an ergonomic handle that makes the drill easy to carry. The controls are designed and positioned to further enhance ergonomics and to facilitate drilling.
Last year Multiquip launched their CDM1H Core Drill. This single-speed model excels in wet drilling applications up to 75mm diameter or it can be used with Multiquip’s Cobra dry drilling bits up to 125mm diameter. The Cobra is made specifi-cally for dry drilling reinforced concrete. The CDM-1H hand core drill is ideal for electrical and plumbing jobs where operators need to drill through walls and floors. The 11A, 115V hand-held core drill operates at 0-1,800 rpm. This unit weighs only 20kg and comes with an adjustable shoulder rest, a three-position handgrip, and it’s designed with an internal water feed feature. For operator convenience a carrying case and tools are also included.

Hilti has decades of experience with diamond systems for cutting, grinding and coring. But controlled de-molition in atomic power plants not only demands comprehensive know-how, contractors also often need special solutions for complex tasks that cannot be car-ried out using standard tools and equipment.
One example of a job that required a specially manufactured solution was a project carried out by the company Norbert Braun GmbH of Münster, Germany. A stainless steel vapour drier in a reactor had to be cut into several sections to allow it to be packed in radiation-tight containers. Braun’s concept involved placing the vapour drier inside formwork and filling the formwork with a special low-viscosity concrete before subsequently using a wire saw for the cutting process. The water-cooled sawing operation was monitored by cameras and remotely controlled so that the time spent by the workforce within the hazardous radiation zone could be kept to a minimum. This was an extremely demanding and innovative procedure, for which Norbert Braun GmbH recently received the “Diamond Award 2009” from the International Association of Concrete Drillers.
Hilti supplied a special high-capacity diamond wire saw system for the project, featuring a higher power output, a pneumatic wire tensioning system and continuously adjustable wire speed control. With this equipment Braun was able to prevent sudden rises in the tension on the wire and greatly reduce the risk of wire breakage. In addition, Braun used special diamond wires supplied by Hilti in three different diameters, which allowed trouble-free completion of each cut.
Pioneering role in dry cutting
Hilti diamond systems in atomic power plantsThe controlled demolition of atomic power plants is a com-plex and demanding operation. Projects of this kind often have to be undertaken by companies with specific experience in this field.
Other methods of controlled demolition in atomic power plants make use of dry cutting techniques. In 2002, Hilti was one of the first companies to supply dry-cutting wire sawing solutions for demoli-tion work in atomic power stations. This technique allowed considerable cost-savings when removing contaminated concrete or steel structures as the costly and time-consuming task of sealing off the cutting area and the evaporation processes required for the disposal of contaminated concrete slurry were no longer necessary.
As part of a demolition project in 2008 at a reactor in Germany a Hilti dry-cutting diamond wire saw was used to cut an access opening in a curved concrete wall to allow removal of material from the reactor core.
Comprehensive range of productsHilti diamond systems provide a broad range of solutions incorporating dry-cutting techniques for use on reinforced concrete and steel. These include diamond wire saws with continuously variable speed control, adjustable wire guidance systems and high-performance diamond wires.
The know-how incorporated in Hilti diamond sys-tems is in big demand for technical demolition in atomic power plants, especially with the dry-cutting technique.
Project engineering with tailor-made solutions makes Hilti a reliable partner for controlled demolition in atomic power plants. The photo shows an automatic drilling system developed by Hilti in use on a concrete container.
Hilti also supplies a range of core drilling machines and dry-cutting core bits featuring the innovative poly-crystalline diamond technology. Core bits of this type achieve higher coring performance than conventional segment-type core bits, and only one specification is required for use on various types of concrete.
For surface decontamination Hilti recommends hand-guided diamond grinding systems in conjunction with the appropriate vacuum removal system for dry dust. These power tools, discs and appliances have been developed together to form matched systems providing high suction performance.
Individual solutionsHilti is also a source of support provided by teams of engineers with experience of controlled demolition projects in atomic power plants. The manufacturing of special solutions and customization of standard tools and equipment for special jobs is also a field in which Hilti excels. Hilti’s specialists can also provide technical advice, training and repairs where protective measures against radiation are essential.

of the operator using the machine’s remote control far away from the demolition area was another advantage. First Kevin rented a machine from Brock Inc, a demolition robot rental firm in Monroe, Washington. “Demolition robots became a great opening for us as soon as I realized what a profitable complement they were for our business. We could take on a lot more jobs then before due to the efficiency the robots provided. We could also do other types of jobs thanks to what the Brokk robots added to our services,” says Kevin Bohm.
It was at World of Concrete 2006 Kevin bought his first demolition robot, a Brokk 180. Shortly after he bought his second 180 and after that a Brokk 90 was added. “I am very satisfied with Brokk, but training of the operators is an absolute necessity in order to operate the machines correctly and get the maximum out of them. Our operators are well trained by Brokk in Seattle, which also put us in a unique competitive situation. The right type of equipment and the right person behind the joysticks,” says Kevin.
Kevin estimates that Alarcon Bohm is six to seven times more efficient with their Brokk robots compared to conven-tional methods. Today the Brokk machines are used at least in one of five jobs and Kevin can see a constant increase of the Brokk operations. But there is some scepticism from clients who have not seen the equipment before. “When I said to a client that we were going to bring the demolition robot through the stair case he questioned if that was a good idea.
But when he saw the machine crawling up the stairs he was convinced in a couple of seconds,” says Kevin. “As
soon as our clients see the robots in action any shred of doubt is blown away.”
Increased working territory
Almost 90% of all Alarcon Bohm’s jobs come from public clients like banks, federal institutions and departments, airports, jails and schools. Very few jobs come from the private sector. According
to Kevin this is an advantage as the private sector is much more unstable to work with.
Alarcon Bohm has also started to take on more cleaning jobs like removal
of asbestos and other hazard-ous materials and hope to
increase this service in the future.
About 90% of the jobs are carried out in the greater San Franc i sco bay area but the company is aim-ing to widen its working terri-tory. They are l i c e n s e d t o carry out de-molition work in the states of California, Washington, Oregon and
Nevada. One
“A Profitable Opening”In the US the Oakland based demolition firm Alarcon Bohm Corpo-ration in California has since the start in 1989 always been a hall-mark for a successful business and once ranked one of the fast-est growing compa-nies in the greater San Francisco Bay Area. Three years ago its President Kevin Bohm took it to a new level with the move into the new service of demo-lition with remotely controlled robots from Brokk.
Kevin Bohm is one of those self-made entrepreneurs that started with nothing and has built his way up. He is proof that the American dream still exists and that you can set out your mind and fulfill your dreams.
Hauling construction refuse
Kevin Bohm is the President of the demolition and recycling firm Alarcon Bohm Corporation, a company he founded together with his wife Patricia in 1989. Bohm started at the age of 19 in the towing business when he got a used tow truck from his father. Some years later he changed his profession and became an apprentice carpenter and moved to the Bay Area in California. It was here he got the idea to start using trucks as a work tool again. But he changed towing for hauling as he found out that there was more money to make in transporting construction waste. This became the initial foundation of the company Alarcon Bohm Corporation with one hauler truck and three dumpsters.
With the right strategy and determined minds the business got a good start and has constantly been growing ever since. After some years the company developed to provide soft de-molition and renovation service, which today has become the core business. In the beginning of 2000 the business took off and during a three-year period it was one of the fastest growing companies in the region with a growth of over 450%. Today Alarcon Bohm has annual revenue of US$15 millions and about 60 employees, which can vary up to well over 100 depending on the workload.
Demolition robots best
choice for Alarcon BohmKevin Bohm has always been alert at finding and trying new methods for improving his services and new business ideas that generate a good return. Some years ago he learned about a method for bringing down structures using electrically pow-ered, remotely controlled demolition machines.
In the environmentally conscious Bay Area of California a device that does not pollute and that can, due to its compact size, access weak concrete floors and very confined areas still with a lot of power would be a success. The safety
Kevin Bohm and his wife Patricia’s company went from hauling con-struction waste to become a fully specialised demolition contractor using among others remote controlled demolition techniques.
“A Profitable Opening”goal is to widen the working area covering Hawaii, Alaska and Arizona.
Besides the demolition robots Alarcon Bohm has a wide range of machinery, which also includes several types of hand-held equipment, excavators and a number of compact machines like skid steers, dumpers and haulers and dumpsters. They are also looking at the possibility to acquire a Brokk 400 in order to take on heavier demolitions jobs but still within the soft demolition and renovation segment.
“Our Brokk operation is definitely an area we want to develop in the future and we have got a very good start during these past three years that we have been offering Brokk services. There will also be a lot of state investments in terms of renova-tions in the near future and with our demolition robots and well-trained operators we will have a good chance to be part of that,” says Kevin Bohm.
Alarcon Bohm is currently negotiating with the US Army Corps of Engineers about a long-term contract to handle demo-lition and renovation jobs on army bases in western USA.
Brokk in the United StatesBrokk is the biggest manufacturer of this kind of equipment and has been present in the US market since the mid 1980s and a lot of machines have been sold. But there are still few contractors using Brokk machines and not so many in each state.
One of Alarcon Bohm’s Brokk 180s set out for a new mission.
The roll-off truck system that Alarcon Bohm is using is rather unique in the US but a common system for hauling all sorts of waste in Europe. The system that uses a hook to pull the dumpster off and on the truck makes the handling quick and easy.

The European Championship of the TYROLIT Cutting Pro Competition was the crowning finale of the 2008 event. On 22 January 2009 more than 600 visitors experienced a brilliant final in the Messehalle Innsbruck. In the end, the result was extremely close: Kim Guldbæk (Nordjysk Diamantboring og Skær) from Denmark won just one point ahead of Paul Maurer (Meister Betontrenn-Technik) from Switzerland.
Inspiring supportersCheered on by the fan clubs from their home countries, the 16 national Cutting Pro champions showed their exceptional skills in the three exercises wall sawing, core drilling and hand sawing. It was clear from the beginning that superior profi-ciency, know-how and experience would not be sufficient to win this championship. The fastest athletes were those who mastered the given conditions, live on stage, in the limelight and in front of fans going wild by keeping cool and concentrat-ing on their task, whilst being encouraged by the TV presenter Charlotte Engelhardt.
In the visitor’s area, the excitement was close to boiling: Vikings blew their horns for the Norwegian Svein Roger Bye (Moby). Cow bells chiming in a sea of Swiss fans, each dressed in T-Shirts in their national colours, motivated Paul Maurer (Meister) and Urs Birrer (Bibi Betonbohrungen). Enthusiastic Spaniards drove their Spanish Champion Miguel Zollo Sevilla (Perforación y Corte Saldaña) to an outstanding performance. The Austrian Markus Netztaler (Schaidraiter) made use of his home advantage and the wave of excitement.
During the award ceremony, the enthusiasm of the ath-letes came through and turned this last part of the competition into the emotional climax of the evening. The spectacle faded out with a great party. An essential part in the success of the event was the entertainment provided by the Cheerleaders of the Swarco Raiders, the drummers of Beats & Noises as well as the rock band Groovebreakers.
Double Nordic Victory in Tyrolit’s International Cutting Pro Competition

SPECIAL DELIVERYWhen it comes to diamond tools and equipment, there’s always something new at US Diteq.
facturers a r o u n d the globe. Among th e c o m p a n y ’ s key partners are Shibuya, Dustless Tech-nology, Keyang, Powers Fas-teners, Subaru, and EMAK. The alliances provide production resources that complement Diteq’s US based light manufacturing and warehouse capa-bilities, which include its headquarters 1,400m2 facility in Lees Summit, Missouri and a 2,300m2 facility in Anaheim, California.
Another advantage of Diteq’s niche philosophy is that it creates a wider range of opportunities to reach prospective buyers. Distributors range from the traditional channels of concrete equipment and supply dealers, rental distributors, and specialty trade suppliers to hardware stores and fire and rescue supply houses. Diteq also sells directly to Concrete Sawing and Drilling Association members.
“We try to be as discriminating as our customers when it comes to selecting quality tools to offer,” says Steiner. “That’s why we work only with partners who have a proven com-mitment to quality manufacturing. As a result, customers aren’t left wondering whether a product will meet a par-Dan Steiner, President of Diteq.

Diteq president Dan Steiner readily admits that his company is not the biggest manufacturer in the diamond tools and equipment business. But if a construction or demolition contractor is looking for a specific tool to fit a specific need, chances are Diteq has it.
“We’re trying to put our mark on the industry by be-ing a one-stop shop for filling a lot of niches,” says Steiner. “When people buy one type of product from us, they often find that we have other tools and equipment that they’re looking for.”
More then two centuries of experienceSuch a broad product range is rather remarkable considering that the company, with 35 employees, has been in existence for only six years. Yet despite its relative youth, Diteq’s core management team has more than two centuries of combined industry experience.
“Though our beginnings are rather humble, our experi-ence has helped us grow quickly,” says Steiner, who joined DITEQ in 2005 after spending more than 30 years at Husqvarna. “We have a good understanding of what con-tractors look for in tools and equipment, and the resources to quickly roll out new products or refine existing ones to meet those requirements.”
The depth and breadth of experience has enabled DITEQ to identify and forge strategic alliances with other manu-
SPECIAL DELIVERYticular need or be a worthwhile
investment.”But Diteq is more than just a
matchmaker for products and niche needs. From the very beginning, the
company built its reputation based on the innovative diamond blades and related tools that
feature Diteq’s proprietary ARIX diamond arrange-ment technology. Comparing the blades with high-quality tyres used by racing cars, Steiner says the precise alignment of ARIX blades increases their cutting speed by 50%, and extends their life by 30%.
Steiner adds that ARIX technology’s complexity has so far frustrated any attempts to decipher its secrets. “There is truly nothing else like it, both in terms of its design and the performance it provides users,” he says.
Diteq is now implementing ARIX technology into small diameter blades, core bits, and stone cutting fabrication tools. The company has also recently introduced a new line of 100mm to 406mm vacuum bonded utility blades that can cut both metal and concrete. This has attracted interest not only from its traditional construction and demolition customers, but also emergency services professionals.
“Up to now, using a diamond blade to cut metal has been un-heard,” says Steiner. “Because seconds count when it comes to saving lives, many fire departments and rescue squads are now discovering the value of these versatile, time saving blades.”
Although DITEQ’s ARIX blades are produced in Korea, they will not be severely affected by the outcome of the anti-dumping suit against Chinese and Korean made blades.
“Prices on diamond blades across the industry will likely go up, but we’re glad to see this issue resolved because it was getting out of hand,” says Steiner. “Too many contractors were treating blades like commodities and trying to cut their costs for the wrong reasons.”
Diteq’s expertise in diamond blade applications is paying off in other ways. The company’s newest partnership with Cardinal Saws and Blades of Conshohocken, Pennsylvania, has yielded new opportunities in the green concrete mar-ket. Among the recently introduced products are the new G-TEQ lightweight saw, the Liberty Bell blade, with its distinctively shaped arbour hole that fits all Soff-Cut® saws, and the C-TEQ crack chaser that can smoothly handle even the most erratic fissures.
Finding such synergy in products and equipment provides innumerable benefits in the field. At the World Trade Centre site in New York City, CSDA contractor J.P. Hogan of Staten Island, New York, is using the Shibuya 402 core drills and Diteq C-52 core bits to remove existing east wall infrastructure and make way for construction of the new Freedom Tower. Hogan, a subcontractor for the multinational Phoenix Group construction consortium, uses a specially crafted diamond wire saw, then core-drills
the panels for lift-out and removal. Hogan quote about the project, and how the core drills
and bits have contributed.
Beyond cutting and drillingSteiner notes that as a full-line supplier to CSDA, the com-pany supports all phases of a contractor’s operation. “We also supply heavy-duty electrical cord, battery powered spray systems, high-quality pump sprayers, and carbide drilling steel and hammer bits,” he says, citing the new Concrete De-stroyer as an example. “This non-toxic, environmentally safe biodegradable liquid dissolves Portland cement on contact, making it ideal for cleaning up equipment and tools. It can even remove concrete that is years old,” says Steiner.
So too is Diteq’s support of the concrete preparation industry. The company’s expanded product line includes 200mm to 460mm grinders with diamond grinding heads and Teq-Lok diamond inserts, and special diamond buttons
and PCD (Polycristaline Diamonds) heads. “We also stock a full line of abrasive blades, grinding wheels, and sandpaper products,” adds Steiner.
Diversity and an eye for detail will likely serve both Diteq and its customers well as economic un-certainty shrouds what was already shaping up to be an uncertain market
for construction and demolition services. “Money for construction loans is only going to get tighter,” says Steiner. “One hopeful sign
is that almost everyone agrees upgrading roads, bridges, sewers, and other public infrastructure will be critical to keeping the US economy going.”
Other issues are far more certain, such as the need for contractors to take greater care in safeguarding their work-ers and the environment from silicosis. “It’s a huge safety concern that will receive much more attention, particularly when working in confined spaces,” says Steiner. “We’ll also see more manufacturers develop ways to separated slurry into a material that can be safely disposed or reused.”
Regardless of what opportunities and issues contractors are presented with, Steiner has no doubts that Diteq has prod-ucts to help meet them. “We want people to come to us first,” he says. “We may not immediately become their primary tool and equipment supplier, but we’ll be happy to be their number two or number three supplier. As they get experience with our products and learn more about what we offer, we’re confident they’ll keep coming back for more.”

New York Street Stitched Up!
Property developers Bruntwood Estates embarked on a redevelopment project in the commercial centre of Manchester, York Street. This involved demolishing the old building and constructing a new state of the art of-fice block. To make way for the new development, the basement of the old building had to be drilled and piled. Contractor Sir Robert McAlpine called in drilling and sawing specialists Holemasters Demtech Ltd to cut pockets out of the concrete basement slab so piling could begin.
Extensive Concrete CuttingWhen it came to drilling thousands of holes 112mm diameter, 1.2m deep, in reinforced concrete, Holemasters Demtech Ltd had to get the best diamond core drill for the job. A few less minutes per hole, and a couple more holes per core drill, would make a huge difference to keeping within the budget, and hitting the completion date of the large project.
UK based concrete

Demtech Ltd were
chosen to undertake

job in New York Street,
Manchester.
Heavy SteelDrillers soon found 60mm and 100mm thick steel plates running through some of the cutting area, which looked to be a big problem early on in the job. However, Holemasters Demtech found the AERO® Core Drill was quick, even when drilling pure steel, and a lot faster than at first expected.
Core Drill TrialsTesting to find the best bit was not a problem as Hole-masters had more than eight hydraulic drill set-ups on the site, alongside each other, each with the same motor speed, and all drilling the same concrete. Each set up had a hydraulic autofeed. These conditions ensured there were few variables in the testing process. Holemasters tested core drills from six different companies and it soon became clear that the AERO® Core Drill came out on top as the best product, on speed and life.

Progress to dateHolemasters Demtech completed most of the basement slab drilling in eight weeks to specification and with maximum efficiency, fulfilling Sir Robert McAlpine’s requirements and leaving Bruntwood Estates happy with the progress on the project.
Strong Market PresenceDiaquip, manufacturers and suppliers of the AERO® Core Drills, were very impressed with the professional-ism and thoroughness of the trials Holemasters Demtech carried out. The consistency of the AERO® was proven throughout the project. Well over 3,000m of drilling with the AERO® Core Drills were completed on the job.

Correct marking of abrasives – a must for oSa-membersThere is a huge range of tools in use today that are easy to operate, bear little or no marking and do not come with an instruction manual. This is the case for simple hand tools, such as hammers and screwdrivers, but for abrasive products the requirements are much different. Abrasive wheels incorrectly selected or misused can be very dangerous, causing serious injuries. The range of products in terms of size, shape, specification and operating requirements require explicit marking regulations. International and European standards of abrasives therefore require that the maximum permissible operating speed (in m/s and RPM), the dimensions and any particular restrictions to its use be marked directly on the abrasive wheel. And this marking must be legible and permanent. Unfortunately many products do not meet these requirements and, therefore, give rise to great safety risks. Consequently, the message from oSa to all users of abrasives is “Don’t use a product if its marking is illegible, incomplete or missing!”
Almost every week the oSa-headquarters receive information on insufficiently or incorrectly labelled products marked with the oSa®-logo. If these are manufactured by an oSa-member, a phone call usually helps to clarify the case and admonish the member to mark correctly in future. If however we have to deal with a coun-terfeit or private label product, a lawyer will be used. A severe infringement of oSa-regulations is the missing 5-digit private label number, as this number safeguards traceability from the user/dealer/importer back to the manufacturer. The counterfeiter will in such cases have to sign a cease and desist letter and cover the legal costs. Further possible legal steps are the destruction of the counterfeits and compensation dependent on the turnover. Members of oSa are totally committed to the correct marking of their products. To help members in the correct marking of abrasives, instructions for the different abrasive products will shortly be provided in the internal member section of the oSa website.

Drilling to the Core at Shard London Bridge
part of a World War II shelter and long redundant underground station. Drilling depths of 3m and 150mm diameter through reinforced concrete and cast iron liners were conducted to obtain core samples for material testing, necessary for the predemolition planning.
“It was great to be one of the first contractors on the Shard project, working on an old London site,” says D-Drill south branch manager John Barber. “D-Drill was brought in because of our experience and ability to drill in confined spaces
and our understanding of demolition requirements. We are now expecting to be involved in more drilling and sawing projects as the construction of the Shard continues.”
Shard London Bridge is set to become the UK’s & Western Europe’s tallest building stand-ing at 310m and spanning over 72 floors. The brainchild of Italian architect Renzo Piano, this prestigious project is set to be complete by the end of 2011.

For more than 15 years the Swedish company Midhage Diatip has been a supplier of equipment for re-brazing segments onto diamond tools. In the beginning the range focused on equipment for the retipping of diamond core bits, but recently the range has been supplemented with machines for the production of diamond blades. The business idea is not to compete with suppliers of machines for the big professional diamond tool manufacturers, but rather offer low price options for the small manufacturers or the service shops. The founder of the company, Jack Midhage, was a well-known name in the diamond tool business. In spite of his age Jack Midhage took part in the development of new products and in sales and marketing. Today the late Mr Midhage´s son and daughter are directors and involved in running the business in co-operation with the different manufacturers.
Carina Midhage, who is doing most of the customer contacts, is happy to be able to continue her father’s work selling machines for retipping and manufacturing of diamond tools all over the world and says that there has been an increasing interest in the company’s products in recent years. As a result of the bad times there is a need to repair instead of always buying new and Midhage Diatip can offer the equipment and auxiliaries that make the job easier. “And for the moment our export custom-ers can also take benefit of extra discounts because of the low currency rate on the Swedish Krona,” says Carina Midhage.
The company’s growth has benefited from a
number of trends. Previously the cost of the diamond segments constituted a major part of the total tool cost. Now other costs have become more significant, particularly those of steel centres and barrels, as well as transportation.
The retipping rangeThe top selling model is still the CD 7-28 for retipping core bits. The machine cuts off the worn end of the used barrel at the same time as it cuts neat and ac-curately positioned seats for the new segments. The seats make it easier to braze the new segments and make the whole bit stronger. It is also available as a smaller model, the CD 600, which is lower in price and easier to take to site. These are manual models that work without electrical power but they can also be supplemented with hydraulic motors for the cutting. In addition there are also fully automatic models controlled by a CPU. For fixing the segments while brazing the company’s brazing magnets have become very popular. They are available in different types and with differ-ent dimensions to suit all bits.
Beside this range of machines for the core bits there is also a full range of machines for the repair or manufacturing of diamond blades, brazing machines, a dressing and grinding machine and a
tensioning machine. These machines are designed to suit repair shops or the small series production. The brazing machine, HFCS-1600 SA, is semi-automatic that brazes the segments
onto the blades with a high frequency generator. The preparations and the rotation of the blade are
manual, but the feeding of the segment in position for the brazing is controlled by a pneumatic system.
Also the dressing machine, SD 1200, works half manually. The grinding heads are fed by hand wheels, but the oscillating movements for an even wear of the grinding wheels are automatically performed.
On the tensioning machine, T 1600, an electric motor does the rotation of the blade, but the pressure is manually controlled.
The company is flexible and many of the machines are spe-cially designed by request from customers. Morgan Midhage, who has been in the diamond business
for 20 years, noticed that as the floor grinding market has expanded there has been an increased interest for equipment that can make the retipping of floor grinding plates easier. This demand resulted in the new GH 15 in the programme for brazing segments onto discs, plates and cup wheels. The machine works with a high frequency generator and can braze material up to 15mm in total thickness.

Concrete drilling and sawing operators need the best and reliable tools to accomplish challenging assignments fast and precisely. The tools must be compatible with the machines they are working with and the right quality to cope with the smooth sawing and drilling of concrete and reinforcement.
After EDT Eurodima has done pioneering work in high frequency machine technology and improved the product range, the focus has now shifted to diamond tools. The existing production facilities and processes have been improved with new quality and innovative technologies and the range of diamond

tools for drilling and sawing enhanced.Duramant is the innovative diamond segment
for both drill bits and saw blades. EDT Eurodima developed a new bonding that retains the diamond longer in the segment. Cutting speed in concrete was increased by up to 30% and tool life by ap-proximately 25%. The special drill spikes ease the centring and the start of drilling, so the edging of the diamond tool becomes obsolete, saving time and work. Duramant segments can be used for brazing as well as for Space Welding.
Space Welding is a technology that comes from the automotive industry. EDT Eurodima is the first to apply this welding method in diamond technology for concrete drilling. It generates a high-strength join of diamond segment and tube. The joining process does not imply heat development, so the positive characteristics of material are prevented from being damaged, which would happen when using other methods, such as brazing and laser welding. This technology guarantees highest tool quality for users.
The Precision Tension Guarantee is the new-est of a series of investments in tool quality. For a diamond saw blade, one key quality indicator is the tension of the blade. The bigger the size, the more tension is needed to cut a straight line. There are dif-ferent ways to tension a blade. These are the manual method, where the operator adjusts and tensions the blade or with the EDT Eurodima fully automatic tensioning machine. The machine produces a ten-sion quality sheet, where all the technical data are indicated. So customers get the perfect blade and relevant documentation as the Precision Tension Guarantee. A perfectly tensioned blade avoids side friction, so potential damage and decrease of performance are minimised. The tool life can be increased by a double-digit percentage.

Every third year the French construction machinery show Intermat is held at the Nord Villepinte Exhibition Centre in Paris and is recognised as the second largest international show in Europe after the Ger-man exhibition Bauma.
Record year in 2006In 2006 Intermat had
1,500 exhibitors and at-tracted 209,000 visitors
from 127 countries. More then 45% of the visitors came from out-
side France. The show attracted 16% more visitors then in 2003 but at that time 160 nationalities were rep-resented. But Intermat is truly an international show although some critics believe it has developed into more of a national show.
Good hope for 2009But 2006 was another time, and then the show conveyed an at-mosphere of econo-mic and construction
growth in Europe and for the years
ahead. We know that 2007 was
an even better year and the first half of 2008 was also good. The figures for Intermat 2009 are different and the num-
ber of exhibitors has declined by about 200 down to around 1,300 companies. Sev-eral of the big manufac ture r s have withdrawn from the show, but Intermat does not appear to be that affected by the recession. This Intermat covers 350 ,000m 2 o f exhibition space, i n c l u d i n g a
10,000m2 open-air demonstration area,
which is almost double that of 2006. Some 70% of the exhibitors come from outside France. There will be eight national pavilions represented by Algeria, China, Korea, Spain, United States, Great Britain, India and Italy. The organiser is expecting more than 200,000 visitors with 45% from outside of France.
Confident organiserIntermat exhibition manager Maryvonne Lanoë says, “We are proud to observe that despite the current economic crisis that is affecting us all, Intermat will send a clear sign of
industry players’ anticipation of the recovery. The manufactur-ers taking part in the event are making a winning investment for the long term. Three months before the 2009 edition, we have recorded a 10% increase in registrations in comparison with the previous event, which is a sign of the industry’s con-fidence in its exhibition. Intermat 2009 will bring together manufacturers representing a major proportion of a global market worth US$80billion. In terms of jobs, the market is still buoyant, in particular in France where 600,000 people are employed in the areas of public works and building structural works, not forgetting a further 100,000 jobs in the materials industry. In Europe, this amounts to 11 million people, and 550,000 in the materials sector. The promised mobilization of key economic and political actors over the next few months demonstrates the importance of this sector whose trade fair is a symbol of global and French excellence.”
Hopefully Mrs Lanoë’s predictions will prevail and Intermat will be the start of such a change.
Director of the National Federation of Public Works Jacques Allemand, who is also chairman of the materials delegation and executive president of the Innovation Awards Jury, added, “While market conditions undeniably worsened at the end of last year, we are still optimistic with regard to the future and the development of the construction sec-tor.

as well as attachments, is not very different from Inter-mat 2006. It is a bit shorter and some of the big names are not exhibiting this year. The remotely controlled demolition machine manufacturer Brokk will be ex-hibiting and showing its two new models launched at the end of last year and in the beginning of this. Also Finnish remotely controlled demolition machine manufacturer Finmac Demolition will exhibit and they are launching a new machine at the show. There are also new machines and attachments from Allu, Mechanicca Breganzese, Bobcat, Doosan, Caterpil-lar, Cat Work Tools, Trevi Benne, Mantovanibenne,
VTN Europe, Indeco, JCB, Ramtec, Socomec, Stanley, Genesis and Promove to mention a few.
What is a bit surprising is the ab-sence of concrete sawing and drilling equipment, floor grinders and indoor dust extraction equipment. Although Intermat has not been a traditional show for this kind of equipment, there have been several manufacturers in these product segments exhibiting in the past.

The Italian manufacturer Meccanica Bregan-zese S.p.A. was formed eight years ago in a small town in the Italian province of Vicenza. It was the realisation of a project developed by the Azzolin brothers, who have brought specific technological expertise to the group, making its market position ever more competitive.
The company has developed and ex-panded since the start and has found good market potential in France. MB visited France during Intermat 2006 with a small team mainly for exploratory purposes. The results were pretty impressive, with more than 15 units sold in the period immediately after the event. The initial surprise period of interest proved to be a major incentive and persuaded MB to set up a permanent team in France. The French operation started in 2007 and sales gradually started to rise.
MB currently exports to more than 100 countries, always applying an attentive com-mercial strategy and always responsive to

the technical and economic requirements of its customers. In line with this approach the company has set up a nationwide after-sales network and is currently in the process of setting up a specific service branch to further enhance the effectiveness of its operations in the market.
Four basic modelsMB manufactures four basic models. The BF 60.1 is the smallest in the range and suitable for excavators in the 8 to 14t class. The next is the BF 70.2, for excavators from 14 to 20t, followed by the BF 90.3, for excavators from 20 to 28t, and the largest BF 120.4, for excavators weighing more than 28t.
MB produced the world’s very f i rst bucket crusher, thus creating a niche market as crushing and recycling were hitherto the domain of leviathan dedicated mobile crushers. Productivity is high as the crushed material can be recycled directly on site resulting in a significant reduction of costs. The equipment is also very versatile as all that is needed is a standard excavator for operation. The areas of application of these tools are numerous.

Italian manufacturer Promove continues its policy to expand and will use Intermat to present two new hydraulic breakers. The XP300 will fill the gap in the compact range, while the giant XP7000 is for heavy breaking in quarrying and other severe applications.
These new products represent Promove’s idea of high quality demolition equipment: the perfect combination of high breaking performance, outstanding reliability and low maintenance requirements and real-time sup-port to dealers and customers. XP7000 is the answer to the trend in the increasing sizes of excavators. Carriers over 60t are becoming more and more popular in quarrying because of the severe limitation in blasting and in tunnelling, as the width of roads and tunnels increase and therefore large-sized excavators can be used to advance more quickly.
When high productivity becomes a key driver, increased size of machines used on the front line is the only way to get adequate produc-tion and keep costs under control.
The new mass breaking hammer has been accurately tested for a long time before official launch, showing very positive features in terms of productivity and noise and vibration level the lowest on the market. No spare parts other than ordinary consumables, like chisels and retaining bars, were necessary during the long testing period, indicating Promove breakers to be extremely reliable even in the toughest conditions.
Technical features of the XP range of ham-mers are extended to this model, including the combined gas and oil working principle, blank-firing prevention system, auto-greasing pump,
Two new breakers from Promove on display at Intermat
adjustable frequency/en-ergy, full square-section percussion body with tie-rods completely encased for extra long life, high back pressure and underwater operation kit as on option. XP7000 can also be equipped with the optional tunnelling kit, featuring especially hardened bushings and dust-protecting systems.
Promove is conscious of the importance of cost-control on job sites. Thanks to an accurate study of the hydraulics’ efficiency, XP7000 operation requires less oil flow than any other competitor breaker in its class, resulting in less fuel consumption and less cost/m3 of broken rock.
The smaller XP300 will fit on 5 to 6t excava-tors and on a range of skid-steer loaders, also more and more popular and requiring bigger hammers than the XP250.
The new model is closer to XP400, sharing the same 80mm chisel, and delivering superior class breaking performance. Like all other XPs, it has an anti blank firing system, square section percussion body. Vibration and noise insulation is particularly accurate in order to allow operating under strict urban regulations.
A complete range of breakers up to 10,000 lbs operating through nitrogen and oil to deliver very high energy and productivity along with recognized reliability and low oil flow requirements.The high back-pressure allowed makes initial installation and working set-up very easy.

Caterpillar Work Tools B.V. has introduced the new mobile scrap and demolition shears S320B, S325B and S340B series for hydraulic excavators. These shears extend the range of B-series to the previously released S365B and S385B shears.
“The performance and durability improve-ments will further build on the already excellent reputation of the S300 B shears,” said Caterpillar Work Tools B.V. commercial manager Dave Becktel. “With an emphasis on quality, value and safety Caterpillar has improved on our already excellent line of scrap shears.”
The shear and knife design improves cutting performance and the hardened piercing tip of the upper jaw maximizes productivity when piercing is required. All S300 shear models are equipped with 360° rotators ensuring a quick and precise placement of the jaws in a cutting position without moving the excavator. The high force-to-weight ratio enhances faster cycle times, resulting in more cuts per hour.
Cat shears are designed to cut and reduce the size of metal items commonly found in scrap yards and demolition sites. The straight lower jaw works with the apex of the upper jaw, compress-ing and flattening the steel before the cut. The straight lower jaw maximizes shear force and

creates a more efficient cut. The new shape of the housing provides
improved protection for shear components and better positions the jaw relative to the stick. The cutting edge design greatly improves the protection of the cylinder that eliminates the use of a cylinder guard by extending the housing to cover the cylinder rod. A new hub design is better protected against damage.
Large access panels on the top, bottom and sides of the shear housing make it easier to service. The unique hub adjustment quickly compensates knife wear. The threaded pivot-pin holds the jaw in positive alignment without the need for external retention. The gap between upper and lower jaw can be easily adjusted, keeping cutting capability high, even as blades wear. The piercing tip in the upper jaw is made of hardened steel and can be repeatedly hard faced, helping increase the intervals between tip replacements.
Safety during maintenance work is enhanced with improved jaw and rotation service locks. A standard flagged pin is used to secure the cylinder rod to the moving jaw. This pin design is very similar to those used elsewhere on a Caterpillar excavator and makes maintenance more intuitive and lets technicians use standard tooling.
The S320B, S325B and S340B series fit Cat excavators weighing from 10t to over 60t. The shears can be mounted on either the boom or stick, and cater to all needs for scrap processing and demolition applications.
Caterpillar supports its work tools with a comprehensive range of before and aftersales services that cover everything from advice on work tool selection to operator training, equip-ment management, and a range of financial and insurance products.

New pulveriser from MantovanibenneMantovanibenne adds a new Pulveriser in its range: RP80 is the new Rotating Pulveriser, 8200 kg weight suitable for 60 - 90 ton excavators. The RP80 with its impressive dimensions has a special feature: the mobile jaw is composed of a plate completely interchangeable. The plate is available in two differ-ent options: one suitable for primary demolition (1 front tooth) and the other for secondary demolition (2 front teeth). In this way, the Pulveriser jaw can be adapted to the kind of work that has to be carried out. The replacement of the plate can be done in a short time. Once the plate has been changed, the RP jaw is as new. This new solution avoids the continu-ous change of single teeth, reducing the machine standstill. Furthermore, the jaws’ compactness makes the crushing work more effective. RP80 is now working on an important Italian job site and its performances are amazing.

An Atlas Copco CC 2500 U was involved in the renovation of the Wankhede Cricket Stadium in
Atlas Copco renovation in MumbaiMumbai, India. The stadium needs to be reno-vated for the 2011 Cricket World Cup finals.
Shri Ganesh Construction, a subcontractor of Supreme Infrastructure India Pvt Ltd, Mum-bai, was carrying out the necessary demolition works. The Mumbai Cricket Association decided to demolish most of the northern and western stands of the stadium and improve the drainage of the ground. The capacity of the stadium will be increased from 35,000 to 39,000 seats and the entrance will be enlarged to make access and departure of spectators safe and easy. The main aim is to give every spectator a clear view of the match apart from comfort and world class facilities. Any corner of the stadium will have free view of the ball crossing the boundary line.
Wankhede Stadium was built in 1975 and is surrounded by residential buildings and skyscrap-ers and the Mumbai western railway track passes close to the stadium. Due to noise and vibration levels the use of hydraulic breakers was prohib-ited. The authorities instead accepted the use of a CombiCutter for the demolition work.
About 7,000m3 of reinforced concrete had to be demolished within a project time of three months. “I completed the job on time and am very satisfied with the performance of the CombiCutter CC 2500 U. I am happy with sales and service support given by Atlas Copco,” says Shri Ganesh Construction owner Phoolchand Jaiswal.
The CC 2500 was equipped with universal jaws, which are fitted with teeth for breaking con-crete and with blades for steel cutting. All blades and teeth are replaceable. It fits on carriers from 22-35t and weighs 2,640 kg. With maximum oil flow of 250 l/min the cutter achieves opening cycles of 3 sec and closing cycles of 2.8 sec.

In the US one of the Washington, D.C. area’s most experienced demolition contractors has successfully controlled extensive dust while taking down the old Waterside Mall, a 4-storey, heavily reinforced concrete structure totalling approximately 111,500m3. Crews were able to suppress surface dust and airborne particles with portable high performance misting equipment, despite the crowded urban location and close proximity to the local Metro station tunnel entrance in what has been called a surgical demoli-tion project.
Engineers from Wrecking Corporation of America knew that the densely populated area and close prox-imity to remaining structures would require extraordi-nary precautions. “The Metro station entrance has a
Dustboss valuable at mall demolition
way of creating a vacuum,” says Wrecking Corporation of America executive vice president Terry Anderson. “If the wind is blowing the wrong way, the dust gets sucked right down. The site was also hemmed in on three sides by structures that needed to be preserved, so we had to do a very selective removal, while pro-tecting the entire surrounding area from the nuisance and potential hazard of airborne dust.”
After researching possible solutions, Anderson decided to rent a DustBoss DB-60. As the largest of the suppression designs from Dust Control Techno-logy, the unit atomizes water droplets to the optimum size for particle capture, launching them 60m or more with a powerful 25 HP fan that generates nearly 850m3/min. With its built-in oscillation, the DB-60
can effectively cover nearly 2,000m2 with a fine, dust-trapping mist.
The DB-60 is a fully automatic ducted fan mounted on a wheeled carriage so it can be easily located to accommodate wind direction or specific work areas. The unit delivers adjustable elevation from 0-50° and a 40° oscillation range, providing crews with outstanding coverage.
“The droplet size is critical to effective suppres-sion,” says Dust Control Technology chief executive
officer Edwin Peterson. “Dust particles tend to be in a fairly narrow size range, so the water should be atomized to droplets near that same size for maximum attraction. Our standard models produce droplets from 50-200 microns, but all of our units are designed to be easily customized for targeting specific particle sizes or for cooling applications.”
The takedownWCA began the project in November of 2007, and the old structure did not go easily. “This was one of the more difficult buildings we’ve taken down in some time,” says Anderson. “We had to fight down every step.” WCA employed a high-reach excavator for the general demolition work, a 45t Komatsu PC400 with a 26m boom. Kinshofer dedicated shears with 360º rotation were used for cutting the approximate 5,000t of reinforcing.
Anderson’s crews also made extensive use of a 90t truck crane and wrecking ball. “It’s a technology that virtually never breaks down,” he said. “And it leaves a small carbon footprint.” WCA also used a 63t Caterpillar 365 excavator to take down the structures, along with three Hitachi 450 excavators with bucket attachments and four Hitachi 330 excavators with a variety of attachments that included concrete pulveris-ers and demolition hammers.
WCA performed all concrete crushing and recycling on-site, with an Extec C10 crusher used to process approximately 53,500m3 of material. The crushed product was used for non-structural fill and backfilling.
“By nature, concrete work generates a lot of dust,” says Anderson. “We felt we had to take strong measures for control on this project. The DustBoss did such a good job that we decided to purchase the unit.”

Buy well, crush well, DownwellA UK based demolition contractor has reaffirmed its faith in Extec with the purchase of a new C-10+ track-mounted mobile crusher. Replacing an existing C-10, the unit joins an Extec C-12, itself a replace-ment for an earlier model, in the growing fleet of Downwell Demolition.
The C-10+ was purchased to allow the com-pany to work efficiently on inner city sites, particularly in and around London, where space is at a premium. “I must admit I was nervous about taking on another crusher in the present economic climate, but we are lucky enough to have a combination of a very loyal client base and a good business reputation, which has enabled Downwell to continually expand. We have plenty of work and projects on the books for 2009, and I am in no doubt that the Extec crushers will play a big part in that continued success,” says Downwell Demolition founder Matt Phillips.
The C-10+ was commissioned on site at the Quantum House redevelopment in Croydon, Surrey, a four-month contract to demolish and recycle a seven storey office block. The C-10+ was then sent to Kingsnorth Power Station in Kent where it processed a mixture of concrete and slag on a seven week contract. “Almost without exception, demolition waste is now processed on site and left for future
development,” says Matt Phillips. “The two Extec machines enable us to process all construction and demolition waste into Type 1 or 6F2 very efficiently, which makes them not only environmentally friendly but also extremely cost effective.”

The International Association of Concrete Drill-ers and Sawers, IACDS proudly announced the winners of the Diamond Award competition at a press conference on 4th February during the World of Concrete 2009 in Las Vegas, Nevada. President of IACDS, Patrick O’Brien presented the gold, silver and bronze awards to the winners from Germany, Italy and Mexico.
Gold Award to BraunThe gold award in this competition was awarded to Braun of Germany for the company’s outstand-ing work dismantling a highly-contaminated steam dryer at a nuclear power plant. The project involved putting the steam dryer in a steel formwork for radiation shielding, encasing it with concrete, and cutting it into pieces via remote control using diamond wire sawing techniques. The cut parts were dismantled using the wire saw and packed in Type IV Konrad containers suitable for final disposal.
Silver to TondinTaking the silver award was Tondin srl, for their work on the project to consolidate the foundation of the Loggia Palace in Brescia, Italy. Tondin was able to devise a high speed drilling system with micro bits to fit into confined spaces to restore the foundation.
Bronce to Mexico and GermanyThe bronze award was won jointly by ADRA Tecnologia en Servicio of Mexico and by Ger-many’s BWW. ADRA’s job on a crucible Mittal Steel repair project where diamond tools were required to cut graphite without the use of water. BWW’s job involved a large roll mill replacement project with severe time constraints to finish the job in only 120 hours.

The results of a CSDA contractor member sur-vey in the US conducted by an independent re-search firm have proven to be very enlightening. The survey, which was completed at the end of 2008 by MemberScope, was conducted to col-lect operating and financial data from contractor members to provide a profile of the membership. “The survey is a great tool for CSDA contractors to gauge how their business is doing compared to the industry,” said Patrick O’Brien
The survey is very comprehensive and includes information about operations including company background, personnel, accounting and finance, and sales and operations, and with a response rate of almost 40%, the findings are
solid. Most respondents are S-Corporations and 25.6% have one or more branch loca-tions. Nearly one third of the members who responded are located in the Midwest. More than half of their work is performed in building renovation with 23% in new construction and 20% in infrastructure, highway, airport, bridge, dams and power plants.
With regards to personnel, there are an average of 25 full-time-equivalent employees at members’ companies with 12.6 of these employees being sawing and drilling operators. The hourly wage for a typical operator who works 40.9 hours per week is US$20.29. Dispatchers make an average hourly wage of
US$22.53 and estimators make US$26.33. A typical manager works an average of 49.8 hours a week. An impressive nine out of ten companies responded that they have a safety supervisor and written safety and environmental health programs in place.
The average estimated sales volume for re-spondents’ companies in 2008 is US$2,663,690, up from an average of US$2,394,578 reported by these companies for 2005, the first year reported in this survey. The average amount of a company’s sales per truck was US$201,155 with a median of US$199,000. Flat sawing ac-counts for 27.8% of total sales with core drilling close behind at 25.8%. Additional services being
offered include selective demolition, decorative cutting, ground penetrating radar and surface preparation.
Operating statement information showed direct operating costs which ranged from an average of US$987,634 for operator/labour costs to US$194,631 for diamond tools. Sell-ing expenses including salaries, advertising and travel expenses averaged US$163,171 while general and administrative expenses, including managers, office and dispatch wages, averaged US$617,468. The average profit among all companies combined was US$209,388 with a median of US$80,000.

CSDA on the Cutting Edge with New Training DVDUS CSDA continues to develop, improve and expand its range of training materials, and is pleased to an-nounce the release of a new instructional DVD and video on the subject of Flat Sawing and Blade Safety. The CSDA has been quick to respond to advance-ments in sawing and drilling equipment, such as electric and diesel power saws, and how they can affect the daily working practices of operators. By staying in tune with all the latest sawing and drilling developments, CSDA ensures it remains on the cutting edge of the industry.
“There is far greater use of electric and diesel saws today than there were 10 years ago, and this DVD was upgraded to meet the technical challenges that operators face today,” says CSDA Safety Com-mittee chairman Skip Aston.
The Flat Sawing and Blade Safety Video helps to provide operators with the skills and knowledge required for safe and effective flat sawing, along with addressing important issues like proper blade tightening techniques. This was a necessity, as CSDA had become aware of some dangerous situations with blades coming loose and separating from the saw.
“Operator safety is paramount, and safe working practices and precautions relating to this type of work are highlighted and reinforced. The video encourages operators and employers to refer to ANSI regulations and adhere to them. Safety is not only a matter of knowledge, but of attitude,” says lead instructor for CSDA training classes Rick Norland.
Training not only benefits the employee but employers as well. Many companies will testify that the rewards associated with employing highly skilled, well-trained teams outweigh the costs of training courses and materials through the quality of their work and the satisfaction of clients.
This new video is also available as an online course, along with many others, via the CSDA website.

CSDA/OSHA Alliance Focus on Defensive DrivingThrough their Alliance, the Concrete Sawing and Drilling Association (CSDA) and the Occupational Safety and Health Administration (OSHA) provide vital materials to advance the safety and training of sawing and drilling professionals and to help foster a safe work environment. A major focus of the Alliance is to develop Best Practices (tip sheets) for the sawing and drilling industry. A new Best Practice entitled Defensive Driving (CSDA-OBP-1003) has just been developed and released in an effort to educate drivers and prevent on-the-job road accidents and injuries.
Cities and towns everywhere are experiencing increased traffic due to the ever-growing numbers of vehicles on the road, and it is important to take all necessary precautions to avoid collisions with other vehicles or pedestrians. The Defensive Driving Best
50 PDi • Issue 1 - 2009 • Feb - March
Practice provides sawing and drilling operators with advice and tips that will help them to remain vigilant behind the wheel and ensure their vehicles are road-worthy. Adherence to the information provided could literally be the difference between life and death for drivers and passengers.
CSDA and OSHA have worked together on safety and health issues for the country’s concrete sawing and drilling industry for almost three years, and have also released Best Practice documents on the subjects of Highway Work Zone Safety and Reducing Silica Exposure. All of these Best Practices are also available in Spanish.
OSHA will be sharing the CSDA booth at the 2009 World of Concrete, 2 – 6 February in Las Vegas. Representatives from OSHA will be present to answer any questions attendees have that relate to the health and safety of workers, specifically those employed in the sawing and drilling industry segment.

US Demolition Asso-ciation’s new branding initiative includes re-vitalised website, logo and tagline promiseDemolition contractors, engineers, general contractors, government regulators, the public, and the media now have a new authoritative source of information of all things involved with the demolition process at the National Demolition Association’s redesigned and revitalized website www.demolitionassociation.com.
As part of its strategic growth plan for the future, the Association is accompanying the unveiling of the massively upgraded website with the introduction of a new logo and a new organizational tagline, “Making Way,” to communicate the promise that progress accompanies the demolition process. “The demolition industry has evolved into a very diverse and sophisticated business since the founding of our Association 37 years ago. Today it includes not only demolition contractors, but also companies involved in the broad spectrum of demolition-related services,” explained Michael R. Taylor, CAE, Executive Director. “We want our website to be the foremost source of information for all of these constituents, which is why we completely revamped it to put everything visitors need at their fingertips. It’s now the gateway to all information needed on the demolition process, on a worldwide basis.” The fresh, concise redesign and the enhanced, simplified navigation system enable visitors to quickly find what they are searching for on
the site. One of the most noteworthy additions to the site is a series of new videos, which answer questions such as “When is Demolition Needed?” “What is the Process of Demolition?” “How Does our Work Benefit Society?” and “How Does the NDA Supports its Members?” Other features of the website will be safety-training courses, a member or supplier locator, access to the Demolition Safety Manual, or downloads of the training videos.
The new logo found on the National Demolition Association site – a stylized wrecking ball within a box – presents a streamlined look of commitment and competency. The simple, bold statement repre-sents the past, present, and future of the demolition process.
Developing an appropriate tagline to convey the value of the demolition process led to the choice of “Making Way.” “This short, bold statement captures everything involved in demolition from demolishing structures to abating asbestos, cleaning up weapons site or remediating Brownfields,” Taylor said. He pointed out that many of today’s demolition firms are vertically integrated, owning their downstream buyers. “Many of our current members also provide services that may include construction and demolition debris recycling, landfill operations, and salvaging, while others perform hazardous material management and remediation which often precedes the actual structure take-down,” he added. These businesses, as well as civil engineering, architectural, and general contracting firm, are all viewed as being part of the demolition process.
According to Taylor, the phrase “Making Way” conveys the fact that demolition professionals make way for the future, for new development, for historic preservation, for better schools, safer factories, and more jobs. “We ‘make way’ for a safer environment, cleaner streams, better public service, and economic progress.”
