WHERE EXPERIENCE

COUNTS

Also branch magazines suffer in bad times Dear Reader The holiday season is either over or ending for us in the Northern Hemisphere. I would say most of us are coming back to a difficult business climate and that certainly goes for us that produce business related magazines. Something that has always surprised me is that when things get tough many companies dramatically cut their costs for marketing, almost like in a panic. I understand that all variable costs are the first to be cut before cutting salaries and personnel. But still for manufactures, distributors, agents or contractors that offer services, exposure is an absolute necessity. Nowadays when efficiency is vital it should be even more important. Previously when labour costs were less expensive sales forces were much bigger and manufacturers and sales companies could spread the message face to face by their own personnel. But today it seems to be done very much with the help of social media, exhibitions, direct mail and trade magazines. But as soon as things change and there is a new recession approaching companies put the breaks on. As we are a specialised trade magazine publisher we are a thermometer for the market’s health. We always get the first signals when a recession is approaching. I wish it was the same for upturns in the economy. But when there is a boom manufacturers try to make up for the loss of exposure during the recession, a loss that they have created themselves. Why not do almost the opposite. Here in Sweden there is a saying “Gather in the barns” during good times so you do not need to go down in standard that much during difficult times. It does not matter how much exposure you create during good times, even if it is three times as much as your competitors, if you are almost invisible during bad times you are forgotten. And unfortunately the market forgets fast. So my recommendation is to provide a more even exposure over good and bad times and try to stay visible. Try to spend more or less the same amount of money in bad and good times. But for that to function some planning is needed. Maybe a marketing fund or an endowment can be a good idea where marketing money is saved for bad times. For trade magazines like PDi that are independent, without any support from branch associations, large fluctuations in the economy are quite difficult to manage. It is a struggle to maintain the same quality level in terms of producing in-depth features, surveys, site visits, company profiles and attend trade shows around the world. But as PDi was set up in 2000 we have experienced several ups and downs and managed to get through. Let us hope that the rest of 2013 will result in a slight improvement all over the world and that it will continue to a more stable and strong market in 2014. The last decade has been a little bit of a rollercoaster Photo: Vito Gogola.

Words from the IACDS President

“Let’s create a smorgasbord of courses to choose from” We have had a fantastic summer, especially in the far Northern Hemisphere where I live. Everyone I have spoken to after the holidays have been so positive. It seems as if all have found strength for the autumn and everyone is talking about the great summer we had. It seems that not only in Sweden we had good weather it has also applied across other parts of Europe. This shows to me the importance of ‘high pressure’. If we look at our industry the situation is quite different, as we do not have high pressure. In the best case we could say that what we have right now are scattered showers. The industry mainly talks about how difficult it is to recoup the work and the problem is the cost of labour. If you have a well established company, a company with its own staff that has been working with demolition and concrete cutting for say 6-10 years you at least have notice of 4-6 months, in Sweden. Compare that with the anticipation you have when you are counting on jobs. Besides this the staff in an older company also have higher wages than a young company. We know of this and may also explain the difference for our clients. We are more expensive because we have trained and skilled workers and thus slightly higher overheads. Minimum wages in the construction industry in Sweden are today about SEK140/h (EUR16). The problem today is that we can hire staff for under SEK100/h (EUR11.5), but on the news we can see examples of how companies have found labour for about SEK50/h (EUR5.75). Labour costs have fallen to completely unsustainable levels, which is impossible for serious companies. How is this possible? A carpenter who currently works with new house production is of course more or less a fitter. The houses will be delivered as if they were packaged by IKEA and assembled on site. Read the manual and you have in eight steps installed a whole house, simply speaking. To become a carpenter or concrete worker and carry out this work a special training is required, of course. The concrete cutting and demolition business is today one of the hardest and heaviest occupations in the construction industry with dismantling, sorting, recycling, landfill, knowledge in statistics, hardware knowledge and personal protection. There are no manuals for this job. The list of the required knowledge of our workers to demolish a house can in principle be any length. But nowhere around the world is there special training for this profession. We can possibly find shorter induction programmes, but no training that takes a comprehensive approach to concrete cutting or demolition. Here I see that we as an association need to do much more. Instead of betting on long uniform high school training for concrete cutters

and demolition contractors, compared with three years of training to become a carpenter, I see a lot of small-certified short courses. Courses that you can pick from just like a smorgasbord. For example in Sweden we have no requirement for training to handle a demolition robot. I think this is really weird as we have all the manufacturers of demolition robots in our country. I believe it requires training for the same type of work in England. How hard can it be that we are all working for the same goals and to implement the programme in all EU countries? In the same way, we could work our way through a smorgasbord. We do not expect that anyone involved in the European demolition and concrete cutting industry should have a long and uniform, relevant education. But we require training for people working with PCBs. Compare also with asbestos work, here there is a four-day training and it is the same for all EU companies. Let it be the same thing say for silica, arsenic, creosote, soil remediation, driving compact loaders on a work site and more. What we should focus on in all branch associations is to create shorter courses for contractors in different types of disciplines and the training courses should be standard all over Europe. If a contractor is tendering for a job without having undergone a training course that is required he should not even be able to tender for the job. Each training course alone should not be long or expensive. I will expand my proposal and in more detail in my next column. But it is my firm belief that this type of smorgasbord, with many short courses, is a perfect way for concrete cutting and demolition industries to have unified and legitimate licensing. To learn and by legislation force clients to use only licensed personnel is the best way of eliminating cheap and unskilled labour. Professional contractors can never compete with extremely low labour costs, but we can always take up the game as long as we talk about skills and training. Lars Sandström President of IACDS

I’ve lost 88 kilos this week. The new husqvarna K 6500 electric power cutter really makes you

feel the force of a new generation high frequency technology. A massive 5.5 kW (using 3-phase) output at the spindle means outstanding power/weight ratio. And you’ll easily move it around, the K 6500 and the PP 65 power pack weighs only 10 kilos each. That’s 88 kilos less than equivalent hydraulic systems!

EDA Words from the EDA President

Open house: New EDA president submits her first column Since the last issue of PDi there has been a change of leadership at the European Demolition Association and PDi Magazine would like to take the opportunity to thank the former president Giuseppe Panseri for his contributions in the magazine. We also would like to welcome the new president Pilar de la Cruz. We are very happy to announce that Pilar is actually the first woman in this position. Below is her first column: I am Pilar de la Cruz, a second generation demolition professional from Madrid, Spain. It is my honour and pleasure, as president of the EDA, to address you through this column, as my good friend and colleague, Giuseppe Panseri, has been doing over the last couple of years. My duty as president started recently at the EDA Convention held in Milan, so I will be following up on the work of my predecessors, becoming the first EDA president from Spain. I hope that you can use the comments I am sharing in this column, as food for thought. As the summer is getting close to its end, there is an image that comes to my mind to start this column, which is ‘open house’. In most of Spain, with the heat of the summer, the houses warm up during the day, and it is so pleasant to open the windows and doors at night to get some fresh air coming through. Everything stays the same in the house, but feels so good to have a natural breeze, which is more intense towards the end of the summer. Over recent years I have listened to many of my colleagues at the EDA speak about the generational change, and also the changes to companies that come with the new generations. And being a second generation demolition professional myself, who had the opportunity to learn about the industry directly from my father, I do feel the change. As it has been said before, the world has changed so much over the last few years, so our companies also have had to adapt quickly to these changes to survive. But, most importantly for me, the demolition industry has changed so much that it is also a good time to open the house. The demolition industry is no longer just about taking down a building or structure. This industry is about handling the space change, taking care of customers’ needs to ‘leave an empty space’, as my good friend and demolition expert Beatriz Petralanda

says. To do so, we need to work together with other industries connected to demolition. And I believe these industries should all be seeing it as part of what is now called deconstruction, which is hazardous waste decontamination, concrete sawing and drilling, dismantling, decommissioning, demolition, preparation for recycling and recycling. These activities are all connected. So in order to generate this fresh breeze, the EDA is inviting all related industries to celebrate next year with an open conference to include debating sessions about our work together, called “Deconstruction forum”. It will be held on 12 to 14 June 2014, so please save these dates in your diaries and further information will be made available in the weeks ahead. Pilar de la Cruz President of the European Demolition Association About EDA

The EDA was founded in 1978 and is the leading platform for national demolition associations, demolition contractors and suppliers. The EDA has a strong focus on developments in Europe, which are of interest to the demolition industry.

Strong second quarter for Wacker Neuson Metso acquires Chinese steel foundry Pilar de la Cruz, EDA President, VD Voladuras Demoliciones y Desguaces SA, Spain

PDi • Issue 4 • July - August 2013

Metso has completed the acquisition of the steel foundry in Quzhou City, Zheijang Province, 400 km Southwest of Shanghai. The assets of Quzhou Juxin Machinery and Quzhou Chixin Machinery and approximately 220 employees have been transferred to Metso. The value of the acquisition has not been disclosed. The acquisition improves Metso’s capabilities to supply wear parts to its mining and construction industry customers in China and other markets in Asia-Pacific “I am really pleased that we were able to close this important acquisition,” said Metso mining and construction services business line president João Ney Colagrossi. “ It gives us good starting point to

The light and compact equipment group Wacker Neuson has reported an upturn in business in the second quarter of 2013, compensating for the weak start to the year. Second quarter revenue increased by 15.8% reaching EUR329M compared to EUR284.2M in the same period last year. The onset of construction activity in April had the effect of relieving market tensions resulting from the late start in some countries. “2013 got off to a slow start due to sluggish economies in many target markets and poor weather conditions in the northern hemisphere. In Q2, however, our revenue rose 28% on the prior-year quarter to a new record high for the company. Despite a significantly more intensive competitive landscape, we were able to successfully maintain and in some cases expand our position,” said Wacker Neuson SE chief executive officer Cem Peksaglam.

Looking forward By Richard Vann

Richard Vann is managing director of the RVA Group, a UK based specialist engineering consultancy providing management services for large scale, high hazard and complex decommissioning, decontamination, dismantling and demolition projects. He is a past president of the Institute of Demolition Engineers and the Institute of Explosives Engineers. He has almost 30 year’s demolition and decommissioning experience, and plays a pivotal role in continuing to shape industry developments. Of course the global economic climate of recent years has brought many negatives to the demolition sector. The pressure to undercut competitors’ prices to win work has become so great that unfortunately some demolition firms have not had sufficient resource to execute projects to the required standards, and many others have gone out of business all together, however there have also been a number of positive developments. I applaud the cultural change taking place within the discipline. A shift in mindset now sees more and more demolition and decommissioning engineers, managers and directors striving to future proof their careers and businesses by continually developing their skills and knowledge. This has certainly been the case in the UK, helping the sector attain a greater level of credence worldwide. We are increasingly seeing the experience of the most technically equipped professionals being sought overseas. There are some similarities across the US and Europe, but UK standards and methodologies are commonly recognised as the benchmark. Further afield in the Middle East and Asia for instance, clients readily acknowledge that UK expertise can add a great deal of value to their projects, hence a number of UK organisations have a growing international client base. Significant progress too has been made with the management of waste. Since its inception demolition has been a committed recycler, acknowledging the commodity value and demand for materials that can be salvaged during domestic, commercial and heavy industrial executions of work. In reality demolition was probably one of the first ‘green’ disciplines, and as global environmental

regimes have become more robust, clients have heightened their commitment to reducing, reusing and recycling. We are also enjoying and encouraging the greater level of teamwork and tripartite alliances being forged between client, contractor and consultant. As project complexities and challenges increase, leading demolition professionals are seeking to share knowledge and specialist insight. The industry has come a long way in its willingness to communicate and peer-interact; this momentum should not be lost. Demolition is not a black art, and the likelihood is that many challenges will have been encountered in some form or other before. There is sufficient expertise and talent within demolition for us to devise safe, environmentally sound and cost-efficient solutions that demonstrate the degree of engineering aptitude within our specialist field, should we be open enough to embrace them. Adversity is after all, the mother of progress. Richard Vann is managing director of the RVA Group in UK.

It is anticipated that the first building extension phase will be completed in the third quarter of 2014. This covers site development, erection of a logistics warehouse over an area of approximately 47,000m2, as well as the construction of a separate administrative building. The site should be operational within the third quarter of 2015. The investment for the first extension phase is over EUR100M. In the final phase, Liebherr will have a warehouse area of about 170,000m2, as well as an administrative building covering an area of 4,500m2 on the 360,000m2 site. Several factors were decisive in selecting the location, including the proximity of the A7 autobahn, as well as the area available for further expansion. Another factor was the large number of Liebherr construction machinery plants in Southern Germany, Austria and France. For parts storage, a 38m high-bay with 60,000 spaces for pallets will be built and for logistics, there will be a 29m warehouse for 122,000 containers with a potential for handling 3,500 containers/h. In the remaining, 20m high part of the building, provision will be made for manual storage areas with 25,000 pallet spaces and a storage zone, as well as workspaces for customer specific consignment, packaging and dispatch. Using 22 transport loading bridges, the spare parts will loaded onto lorries and vans and sent to customers and dealers by the quickest route possible.

Boels progression into dust suppression The European rental company, Boels Rental, has placed an order with Italy’s DF Ecology for 20 of their DF Smart portable dust suppression units and painted in their distinctive orange livery. DF Ecology is a sister organisation to lighting set manufacturer, Tower Light, and is based alongside the Tower Light manufacturing plant in Villanova d’Ardenghi near Milan, Italy. Boels already has an extensive fleet of Tower Light lighting products. The DF Ecology range first came to their attention at the Bauma exhibition and decided to invest in DF Ecology products principally because of demands from their clients to provide environmental beneficial products. DF Ecology manufactures an extensive range of water based dust suppression products under the Dustfighter brand. Dust suppression on construction sites is becoming an important aspect to ensure the health of site workers. The DF Smart is designed to provide workers with safe protection from airborne contaminates. It is ideally suited for contractors working with dust producing equipment, such as disc cutters, wall chasers and similar machines. The DF Smart produces a fine mist of water through a series

of high-pressure jets. The mist is then propelled onto the site by a powerful fan, rendering the area free from unhealthy and hazardous material. DF Ecology’s research suggests that the DF Smart will become an essential health and safety component with trades, such as builders, landscapers, light demolition contractors and recycling agencies. The DF Smart operates from ordinary mains power, 230V 50 Hz 2.2KW and weighs just 77kg with wheels for easy transportation. It consumes water from 3.6 to 5.8litre/min at 2.5bar via a quick-release standard water hose connection. Boels Rental has more than 300 locations in the Netherlands, Belgium, Luxembourg, Germany, Austria, Czech Republic, Poland, Italy and Slovakia. It is regarded as one of the leading European rental firms.

A first for a Terex Mac 25 pick and carry crane Koodaideri Contracting Services is Western Australia’s first fully indigenous owned lifting company. The company specializes in lifting, but also carries out other contracting work within the region’s rail and construction industries. “As we were just becoming established we didn’t want to go too big, too soon so we decided on a Terex Mac 25 pick and carry crane because it was the right size for our needs,” said KCS managing director Peter Todd. “With mobility as the primary requirement, we spent some time investigating the different cranes available in the market. We work on construction sites and in mines with rough tracks and we needed a crane with the maneuverability to get to any of the lifting sites.” The Terex pick and carry crane range includes three models with lifting capacities ranging from 15t to 25t. The new Terex MAC 25 SL superlift counterweight system is designed to provide additional lifting capacity to all current Terex MAC 25 pick and carry cranes and can easily be retrofitted onto earlier models to increase their lifting potential.

New Allied-Gator MT technology changes shearing Allied-Gator is now offering a new blade design exclusively for the MT mobile shear with the introduction of patent-pending serrated gator blades. Results from extensive field tests have shown serrated gator blades outlast traditional

current Allied-Gator MT customer regardless of tool size, and no product modifications are needed to the MT. “The serrations of the MT’s new blades are designed to progressively pass through material like a saw blade rather than forcing the shear to chop through a large mass of material like an axe,” said, Allied-Gator sales and marketing manager Mike Ramun. “This new blade design does not rely solely on sharp shear blade edges to achieve the cut. Instead of a snipping effect, these blades generate a tearing action. This allows the MT shear to grip and tear scrap materials, which is a far more efficient cutting method than the traditional ‘scissoring effect’ utilized by all other mobile

shear blades up to 50% longer when processing general scrap, and up to 90% longer when shearing steel wire and cable. This new technology is an option, which is available to any

shear blades.” As the MT’s dual moving shear jaws close on structural steel, each serration systematically yields and tears scrap material along the blades’ cutting path. “This new method of shearing greatly reduces the overall wear and tear to the tool. It’s like perforating a sheet of paper as you tear it,” said Ramun. Traditional blades force steel wire and cable to the throat of the jaw and cause uneven wear and damage to that specific blade area. Uneven blade wear has caused most recyclers to dread cutting steel wire and cable with their mobile shears. With serrated gator blades in the MT, the serrations trap steel wire and cable along the blades as the jaws close. This allows the blades to progressively rip and tear the cable apart on its way to the throat. The new technology is also effective in processing troublesome materials, like stainless steel and thin sheeting. The patent-pending Allied-Gator serrated gator blades are available for all 11 sizes of the MT Series multi-tool line.

Historic lock restored in the UK

In the UK concrete cutting experts from D-Drill were called in to help restore a historic lock in the county of Berkshire and had to guard against environmental damage. D-Drill was contracted by construction company Galliford Try to restore the reinforced concrete embankment of the Old Windsor Lock because it was starting to move and break-up. The lock, which was built in 1822, is maintained by the Environment Agency and it embarked on the restoration work as the embankment was becoming hazardous. D-Drill used diamond sawing equipment to form movement and expansion joints to prevent future break-up of the concrete. The job was made more complicated as no residue could be allowed to seep into the water or into the ground. Special bunds were formed to contain any waste, which was subsequently removed with an industrial wet vacuum and disposed of into a sealed container. The work was carried out during a three-week programme and was made all the more difficult by rising waters during bad weather. “This was a job that called upon a range of skills and expertise of our team, not only the cutting method but also making the site safe and sealed,” said D-Drill representative Johnny Barber. “It was essential to maintain a public thoroughfare and, with that, had to ensure public safety. Also, members of our team had to carry out their work wearing life-jackets, which is something they are not used to. “We worked closely with the Environment Agency and Galliford Try to ensure no waste made its way into the canal. The bund system enabled removal of all contained waste safely and efficiently. A further consideration was that no power supply was available on site, so we arranged to use a bunded 415V, 3 phase diesel generator. “There were regular visits from the Environment Agency to check the work and both they and the client, Galliford Try, were extremely happy with

the way we went about the task and completed the job on time and within budget.”

Keltbray complete phase 1 demolition at London Bridge In the UK Keltbray has completed the first phase of the main demolition work at London Bridge Station. The work is part of Keltbray’s £25M contract for contractor Costain and Network Rail to create an improved and more spacious station with more frequent train services by 2018. During the first phase Keltbray had over 100 people working on the demolition of three platforms and 12 existing brick viaducts. This work was carried out whilst causing minimal disruption to neighbours, passengers and allowed the continued operation of trains. “Our biggest technical challenge was to ensure the stability of the remaining structures during the demolition process,” said Keltbray project manager Nick Smith. “We solved this through the installation of temporary works, including a gravity concrete retaining wall to support the live platforms and tracks. Four machines worked simultaneously along a 150m long face to progressively demolish the arches in 1.5m strips. Maintaining this sequence was essential to avoid an uncontrolled collapse. During the works over 25,000t of material was removed from site with wagon movements peaking at over 150 loads/day.” At London Bridge all parties on site are working to BS 11000 Collaborative Business Relationships. “Working to BS 11000 promotes team work and enabled us to work more democratically with Costain, Network Rail and other parties to ensure we focused on mutual benefit and optimise efficiency,” said Smith. “I am pleased to say that Keltbray has successfully completed the first stage of the complex

18 PDi • Issue 4 • July - August 2013

arch demolition,” said Costain project director Mark Howard. “They have demonstrated their commitment to deliver, have a ‘can do’ attitude with a positive safety culture and display the right behaviour to succeed within a collaborative environment. Keltbray is a strong supporter of our zero tolerance approach to vehicle safety compliance, where we only allow delivery vehicles onto site that are fitted with safety equipment which reduces the risk to London’s cyclists.”

Demco Technic’s Unicut wire saw on the job Demco Technic’s new servo drive Unicut diamond wire-saw has been successfully used on a bridge repair project in Switzerland. Four concrete abutments on the Klausenstrasse bridge project had to be cut into several pieces using the Unicut diamond wire saw. There were about 16 sections that had to be cut for removal, each measuring about 2m2. The average cutting performance was 15min/m2. In addition Demco Technic has launched its latest 16kW Captor concrete cutting wall saw, which can handle blades up to 1.2m

diameter. It can be combined with the Unicut wire saw to minimise investment.

A successful hospital co-operation Demolishing part of a hospital while emergency treatment and operations continue as normal is only possible with the right equipment. It must be quiet and low in vibration, like the Darda CC 420 concrete crusher on a Brokk demolition robot and the CC 320 on an electric mini-excavator. Due to a change in floor use and the necessary renewal of the housing technology at the BG Trauma Centre in Frankfurt/Main, a four storey building section had to be demolished. While the interior walls were made of masonry, the exterior walls and the suspender beams and joists, ceilings and pillars were made of reinforced concrete. A soft demolition method was needed to allow the operation of the hospital to continue. Dust protection walls were used to

isolate the emergency ward as well as various operating rooms from the demolition work.

Compact and strong In the outside courtyard area a Takeuchi TB16 mini-excavator equipped with a Darda CC 320 hydraulic concrete crusher was used. As the machine was powered electrically neither noise nor exhaust fumes was an issue. The CC 320 can break up to 300mm thick reinforced concrete, as well as reinforcement up to 20mm. All Darda crushes generate their crushing power with a pressure converter that is independent of the carrier machine. This makes them very effective even on small machines. Despite their compact design they have a very large jaw opening that enables them to crush thick concrete.

The Brokk 160 and the Darda CC 420 concrete crusher

High performance demolition without noise with the CC 320 concrete crusher and an electric mini-excavator.

No risk on thin floors Inside and on the top floors of the building a Brokk 160 demolition robot performed the work equipped with a Darda CC 420 concrete crusher. Brokk demolition robots are perfect for working inside buildings. With their electric-hydraulic drive train, they are emission-free and quiet, which are necessary requirements for the hospital project. The have low load bearing pressure which is an important factor when working on floors with limited load-bearing capacity. The Brokk 160 is compact and its track width can be reduced to 780mm, so that it fits through most doors. Its digital remote control allows the demolition robot to be operated from a safe distance. With

a breaking capacity of up to 38t, the Darda CC 420 breaks concrete up to 400mm thick while its reinforcement cutters are able to cut through steel to 28mm. The partial demolition of the university hospital went according to the schedule of the structural engineer. The chosen demolition method proved to be advantageous as the reinforcement starter bars had to be preserved in many places. This would not have been possible with concrete saws, and the demolition costs would have been much higher. Using the two Darda concrete crushers on the carrier machines, contractor Bopp Bau was able to demolish approximately 1,200m3 of material in four months.

New Genesis XT Mobile Shears

In the US Genesis Attachments has introduced four new XT Mobile Shear models, increasing the line to eight. The new GXT 445 and GXT 775 straight and rotator models join the GXT 555 and GXT 665 models introduced in April 2013. Shorter in length and height and lighter in weight, the GXT features a centre of gravity that is closer to the excavator, enabling the rotating

models to mount on 21t to 35t excavators that previously could only carry smaller, less powerful shears. “Interest in our new GXT mobile shears is high,” said Genesis business development director David Palvere. “Scrap processors and demolition contractors appreciate that the GXT fits on smaller carriers, reducing their initial acquisition and hourly energy consumption costs.” The GXT also features an apex, where most cutting is done, that is closer to the back of the jaws, improving material gathering and increasing cutting performance and efficiency while reducing maintenance. Additional GXT models are planned, and the complete line will fit 9t to 113t excavators.

Gentle Repair of an

St. Petersburg’s famous Dvortsovy Bridge is under renovation and no percussive equipment was allowed. Only the gentle touch of concrete sawing and drilling equipment. St. Petersburg is one of the most beautiful cities in Europe. Architectural ensembles, palaces, monuments, gardens and fountains - these glorious for all around the world masterpieces became essential symbols of the city, forming it’s the one and only image. Famous drawbridges, attracting thousands of tourists during the white nights, are taking a seat of honour among these symbols. The Dvortsovy Bridge is possibly the best known among them. It was built in 1916 and connects the Dvortsovaya embankment and the Vasilievsky island.

No percussive methods allowed Although there is a perception, even among professionals, that previous structures were made to last for many years, the supporting machinery in the bridge’s granite piers at a depth of 3m below water needed replacing. The work was complicated because the new equipment was larger than the original and there should be not traffic disruption on the bridge. The main issue was a problem of space for the new design, which required the removal of 1,500t of granite. Also the dismantling works should not interfere with the activities of other

contractors. The best solution was offered by the contractor Arasar, which had prior experience on the reconstruction of the Blagoveshchensky and Anichkov bridges. The company offered the solution of using diamond cutting technology. Any kind of percussive dismantling would be ineffective and dangerous. Vibrations and micro cracks, which inevitably arise when operating a pneumatic tool, would cause problems, as the thickness of pier wall left is only 300mm in the upper part. There was a need to guarantee high accuracy and an absence of deformation, which could be provided by diamond cutting.

Difficult circumstances Milling of a 10m3 granite segment weighing 27t was performed in several stages. First, two vertical holes 250mm diameter and 2m deep were drilled with diamond drilling systems. These holes were used for the roller submersible tensioners of the cable cutting system used for vertical cutting. Then with two similar vertical cuts and the final horizontal one, the granite block was lifted out by a crane. Despite the proven technology, some adjustments of progress were made due to the capricious winter weather and a bomb that exploded near one of piers during the Great Patriotic war. Granite blocks have crumbled and cracked and even leaks have occurred. Periodically, when pumps could not cope with the icy water, the dismantling work was suspended and equipment temporarily removed. Drilling on the pier was difficult due to the crushed granite and removing sand from the holes.

Despite all the difficulties, Arasar completed the works on time and the client had the best solution for the task as diamond cutting technology proved its effectiveness on one of St. Petersburg’s most famous structures.

New Attachments: “Shear” Force and “Crusher” Power.

Ramtec upgrades Robi crusher-grapple Ramtec has upgraded the Robi crusher grapple CG35R with a high-speed valve. Weighing in at 2.6t, this model

This year work tool manufacturers for the demolition attachment industry have delivered a plethora of new shears, crushers and pulverisers that are stronger, more productive and cost efficient than their predecessors. PDi’s Andrei Bushmarin reports. The demolition attachment market is growing, albeit at a much slower pace than the players would wish. The annual amount of demolition projects oscillates around the same figures, but the number of suppliers is steadily increasing competition in the sector. In terms of consumption, North America holds on to its leading position, closely followed by Central Europe and Scandinavia. Among emerging economies, South America and Africa posted the highest growth rates. Eastern Europe, which is currently underperforming, is expected to resume growth in the short-to-mid term. As the southern European market is virtually non-existent, Italian and Spanish manufacturers are hanging on by their fingernails, with their chances of survival depending solely on international sales. There have not been any groundbreaking innovations, but the general trend is that attachments are getting increasingly larger and more efficient,

26 PDi • Issue 4 • July - August 2013

while generating less noise and dust. According to US based Genesis Attachments marketing manager Amy Burmeister, high performance, ease of maintenance and noise and dust suppression systems are the key requirements that professional contractors require. The sales and marketing director of Finnish company Ramtec, Benjami Pitkasalo, said that users are becoming increasingly harder to satisfy, requiring more features on their tools while trying to drive the price down. Young demolition companies tend to go for cheaper Korean or Chinese products or rent their attachments. With most respondents believing that the global demolition market is slowly gaining momentum, the outlook for late 2013 and early 2014 is cautiously positive.

Genesis extends range of GXT mobile shears Genesis Attachments has added four new models to its existing GXT line of mobile shears, thus extending it to eight. The new GXT 445 and GXT 775 straight and rotator models join the GXT 555 and GXT 665 shears launched in April 2013. Shorter in length and height and lighter in weight, the GXT shears have their centre of gravity closer to the excavator, en-

abling the rotating models to be mounted on 20t to 35t excavators that previously could only carry less powerful shears. The GXT range has the cutting apex moved closer to the back of the jaws, which improves material gathering and increases cutting performance while reducing maintenance. More GXT models are already in the pipeline, and the complete range will fit 10t to 110t carriers.

is designed to fit 20t to 40t excavators. The most important feature of the CG35R is its ability to separate material after crushing. According to the company, the combination of the wide jaws and crushing force allows users to perform demolition tasks with the CG35R much faster and efficiently than with a conventional cutter crusher.

Demarec to adjust tools to market requirements Demarec, a specialist manufacturer from the Netherlands, is going to overhaul its range of pulverisers, demolition shears and Mutli-Quick processors with a view to adapting them to higher working pressure. The maximum pressure will be raised from 350bar to 380bar, which will result in a 10% increase in capacity. The overhaul has been prompted by the increasing number of excavators that have hydraulic systems operating at a pressure of 380bar. Demapower system tools and those with standard cylinders will undergo the upgrade. In line with the trend towards larger attachments, Demarec has delivered its first 9t scrap shear and is currently working on another two models, weighing 13t and 16t. These will be available with and without the 360° rotation mechanism. Also new from are two grab models, the DRG 25 and 27. They are currently only available in the Benelux market, but export versions will follow shortly. The DRG-25, weighing 1.45t is intended for 18t to 28t

Atlas Copco introduces mobile shear jaws Atlas Copco used Bauma to showcase a new jaw version, which turns its CC 3300 Combi Cutter into mobile shears. Designed for cutting steel structures such as profiles, beams, frames and rebars, these new jaws will be handy on demolition and recycling sites as well as scrap yards. The CC 3300 is modelled on Atlas Copco hydraulic combi cutters, featuring two moveable jaws and two lifting cylinders. One of its most distinctive features is the central pin, which holds both cutter jaws together. This solution reduces the time needed to change the jaws by up to 75%, compared to

Austria-based Wimmer has been developing and improving the Topcut line of demolition shears for about 15 years now. The universal Topcut U, designed for a wide range of applications, was the first in the line, joined later by another four jaw versions. Today “Topcut” shears are available in four weight classes, fitting 16 to 75 t excavators. Just recently, Wimmer has added another model, the 700U, to the Topcut range. The new shears come complete with two cylinders and a speed valve for high-performance demolition. It also boasts a number of features that guarantee long and reliable operation in harsh demolition environment. One involves special covers protecting the cylinder surfaces. Secondly, the oil lines are routed inside the cylinders to prevent them from damage by debris. And the last but not least, the shears are designed in a way that ensures that no screws or bolts are exposed to the breaking forces. The jaw design has been optimized so that users

100t carrier machines. The new grabs feature innovative cylinder technology, which reduces by 50% the force transmitted onto the housing. This solution enables more compact and lightweight construction. Two hydraulic motors built into the housing provide 360° rotation. The range is primarily geared towards heavyduty applications, with all models boasting robust and sturdy construction. Parts subject to regular wear and tear, such as the cutting edge made of 500 HB steel, are readily changeable. The grabs are available with either the Lehnhoff patented quick-coupling system or with a mounting bracket for other types of quick couplers.

Trevi Benne equips premium line with impact booster Another Italian company Trevi Benne used Bauma to debut a new premium line of demolition attachments equipped with a power multiplying device called impact booster. This is an integrated hydraulic unit that sharply increases the excavator’s operating pressure, when it is no longer enough to crack the material being demolished. Thanks to the impact booster, operating pressure can be raised from the pre-set 250bar to a peak of 750bar within seconds. The advantages of this solution are reduced stress on the excavator and lower fuel consumption, since most of the time the machine operates at 250bar, instead of the conventional 350bar, and increases the pressure only when it is needed. The booster also helps increase crushing power and operating speed, which results in the reduction of the open-close cycle to just 3.5s. The premium line includes the primary demolition crusher HC Premium, the multi-kit processor MK Premium,

CP expands RX line of heavy breakers Chicago Pneumatic has introduced five new models

to its RX line of heavy breakers, the RX26, RX30, RX38, RX46 and RX 54. Ranging in weight from 1.8t to 4.2t they fit 20t to 70t carriers. The standout feature of the new RX breakers is the power control plus valve. It is a combined stroke length and start-up mode switching valve that operators can change in the field without opening the hydraulic circuit. The valve enables breaker operators to choose between two different operation modes to optimise productivity for different applications. The first mode is PowerStop Plus, which allows operators to switch the breaker to high impact energy with normal impact rate. In this mode, the breaker

starts only when the working tool is depressed, and is recommended when working on solid ground, large rocks, hard concrete and trenching. The second mode is EasyPower Plus, which allows operators to switch to high impact rate with normal impact energy. In this mode the breaker starts e ve n w h e n t h e working tool is not depressed, and is recommended when working in unstable ground, small rocks, and thin concrete surfaces and when working in horizontal or overhead positions. Common to all RX breakers is the power boost feature, designed to achieve greater breaking performance in tough applications without requiring additional hydraulic input. The enhanced percussive performance is achieved by reusing the recoil energy. As with all breakers in the RX series, the new line-up features the energy efficient gas/ oil hybrid technology and an internal control valve for increased efficiency.

“I am seriously very worried over the market situation in Europe. But we are doing very good in North and South America,” said Indeco Managing Director Michele Vitulano.

Putting trust in North and South America With a very weak domestic Italian market and a scattered European market Italian attachment manufacturer Indeco, based in Bari, put its trust in North and South America. About 40% of the company’s sales are shipped to North America.

Being an Italian manufacturer dependent on the Italian market is currently a very difficult task. The Italian market is experiencing one of its worst reces-

sions in decades. If a manufacturer wants to see any chances of survival export is the solution. “I am seriously very worried and the bad market situation is not limited to Italy,” said Indeco managing director Michele Vitulano. “All surrounding markets like Spain, Greece and other smaller states are really bad too. Middle East countries that used to be rather good have become more difficult. One reason is the strong competition from China and Korea.”

About 40% shipped to North America Indeco puts its trust in some of the more northern European markets and, in particular, North and South America. About 40% of the sales are in North America, including about10% in Mexico. Sales in South America represent10% of the company’s business, and is increasing. Europe accounts for about 25% of Indeco’s business, while Africa, the fastest growing market, is averaging between 10% and 15%. The remaining

25% is mostly divided between the domestic market in Italy and rest of the world. Indeco has owned a US subsidiary in Milford, Connecticut for more than a decade, and operates four service centres across the country. A new service centre recently opened in Portland, Oregon. Two years ago, Indeco established Indeco Mexico in Mexico City which also supports neighbouring countries to the south. Vitulano believes that technicians are sometimes more important to focus on then sales people. Technical advice and professional support is what the users are asking for. Not that he thinks that his products sells for itself, but the sales work is left to about 30 dealers that sell Indeco equipment in the US, Canada, and Mexico.

A complex but growing South American market South America is a prioritized market sector for Issue 4 • July - August 2013 •

Indeco, and the company has dealers in most countries. “But each country in South America is unique,” said Vitulano. “In Europe countries can be different in some ways but the basics of doing business is the same. “In South America each country is a unique and quite complex project and much of the complexity is related to the difficult im-

port legislations.” Argentina has become a very strong market for Indeco, with a dealer located in Buenos Aires and enjoys and about 60% of the market. However, companies need an import certificate for every imported product, something that can take up to two months to secure. Venezuela has a similar requirement. Brazil is different. The import certificate is not a problem to get but the country’s import duty is still horrendous, though it has been lowered over

the last decade. However, it also takes a very long time to get products through customs. “Even though we struggle with these practical and bureaucratic obstacles South America is a very interesting continent right now, which in some cases is booming,” said Vitulano. “We have very good sales in Argentina, Brazil, Venezuela, Colombia, and Chile at the moment.”

New products The focus in Indeco’s product development and product range is still hydraulic breakers. But while the company offers a wide variety of breakers, the company has devoted the past decade to widening the range with other types of demolition and recycling attachments like concrete cutters, pulverizers, sorting grabs and steel shears. In the spring Indeco launched several new products.

The new ISS 10-20, small on size, big on performance The new ISS 10-20 is the smallest shear in Indeco’s range designed for 10t excavators. Like Indeco’s other shears, the latest addition will also have outstanding cutting force due to special design features. They include a dual-profile piercing tip system, four fully reversible and interchangeable steel blades, a dual blade guide system, and deep jaw and long blades, and a cutting register adjustment system. The benefits of Indeco hydraulic shears include a regeneration valve that accelerates no-load movement of the jaw, thus speeding up opening and closing. A heavy-duty pivot group keeps the jaws aligned and prevents buckling, while a large, hydraulic cylinder provides force to deal with any type of working conditions.

The Indeco IBS pedestal boom system Indeco has also launched a new series of products to meet customers’ specific requirements and individual needs. Produced and marketed a few years ago by Indeco North America and Indeco Australia, the Indeco IBS pedestal boom secondary breaking system looks destined to make an impact on many other markets, having already proven to save time and money in many a quarry and mine. Mounted over the mouth of a primary crusher, the systems reduce

bridged and oversized material that slows down crushing operations. The new line of Indeco IHC Series-R rotating compactors has been created to help contractors work even under the toughest conditions. These rotating compactors have continuous 360° rotation. The hydraulic fittings are in line with the carrier boom, the hydraulic rotation motor is easy to access and the upper attachment plate is reinforced.

New line of rotating compactors The IHC compactors replace traditional hand-held equipment and in slope applications, eliminate selfpropelled rollers. Indeco compactors, mounted onto a carrier boom, are hydraulically driven with an oilbath bearing system. This gives a balanced design of compaction force and vibration speed, achieving the depth penetration needed to reduce air voids and move more material faster.

New Pan American Demolition Magazine In July a new demolition magazine Professional Demolition Americas was launched specifically for the North, Central and South American markets. PDa will be produced entirely in the US.

PDa is published by Riverbends Publishing, which operates within PDi’s publishing company SCOP. PDa’s editorial staff, led by well known US industry correspondent Jim Parsons, is experienced in all facets of the demolition industry, and the issues that are of the greatest interest to contractors, equipment manufacturers and customers. Parsons will be supported by another established industry correspondent Luiz Carlos Beraldo, covering the South American market and will be based in Curitiba, Brazil. “I am very exited about this new project. PDa is very similar to its well established sister magazine PDi and will cover the same industry sectors like demolition, concrete sawing and drilling, concrete floor grinding and polishing, recycling, hydrodemolition, industrial cleaning and soil remediation,” said PDa and PDi editor-inchief Jan Hermansson.

Two continents on the go Though not fully recovered from the recession or insulated from Europe’s economic difficulties, the economies of the Western Hemisphere are, on the whole, on the rise. New and postponed projects alike are moving forward. A new sector is rapidly evolving around the growing popularity of concrete flooring, and yet another product innovation seems to arrive nearly every day. PDa will strive to provide the same degree of quality and up-to-the-minute coverage, as PDi, but focused exclusively on news and trends driving this dynamic industry in North, Central and South America. In the US several states have implemented new funding strategies to jump start their highway and bridge restoration programmes, while Brazil is bustling with a variety of projects leading up to next year’s football World Cup and the 2016 Summer Olympics. Contractors are shifting their energies from simple survival to finding ways to improve their productivity and competitiveness, attract and retain labour, comply

with environmental and health and safety regulations, and make the wisest investment in equipment and other resources. And, few jobs can be considered routine in demolition work these days, as megaprojects, site constraints and access issues continue to challenge contractors’ professional skills and innovation. All of this, and more, will be coming to readers in the first and future issues of PDa. “We’re confident that our readers will like what they see, and want to learn more,” said Jim Parsons.

Multi lingual to come PDa will have the biggest circulation in the US, Canada and Mexico. But the magazine will be sent extensively to contractors in Brazil, Argentina, Chile, Colombia, Bolivia and Venezuela. All together professional contractors in about 35 countries in North and South America will receive PDa. The magazine will be published quarterly and circulation is aimed at about 20,000 copies. The plan is also to make PDa multi-lingual in English, Spanish and Portuguese. But it has not yet been decided if there will be summaries of selected articles in Spanish and Portuguese in the initial English issues or if there will be completely separate issues in Spanish and Portuguese. Another option under consideration is to publish Spanish and Portuguese versions on the PDa website, www.pdamericas.com for downloading or reading online.

Valuable and strong supporters “To start a new magazine demands financial endurance

over a number of years. And I speak from my own experience with PDi magazine,” said Hermansson. “To deliver a quality product that will be appreciated by readers takes a lot of hard work and energy. You need dedicated and professional staff and you need to make sure that each issue actually reaches the right audience, which is essential for our valuable advertise r s . We a r e very fortunate to have worked with many good and loyal clients over the years. To launch and produce PDi and now PDa is a close co-operation with our advertisers and also our readers. We have much to thank them for. “I have high hopes for PDa and I have wanted to publish a demolition magazine for the North, Central and South American markets for a number of years. We hope the time is right, as we know that business is picking up in the Americas. We also launched PDi at a very difficult time and it has worked well.” PDa will be sent to professionals in North, Central and South America offering services or selling equipment for demolition, concrete sawing and drilling, recycling, concrete floor grinding and polishing, hydrodemolition, handling hazardous waste, industrial cleaning, handling dust and concrete slurry and related areas. Anyone that would like to subscribe to the new magazine please visit the website www.pdamericas.com for more information.

Quick Couplers wit

The demolition industry is all about family and as a guesstimate family-owned companies account for at least 90% of all market players, suppliers and contractors alike. Austria-based Wimmer Hartstahl is a prime example of a family business. PDi’s Andrei Bushmarin reports.

Alois Wimmer established Wimmer Hartstahl in 1984 in Thalgau, a small hamlet of Salzburg. A mechanical engineer by education, Wimmer focused on manufacturing digging tools and repairing excavator buckets.

Discovering true identity In the first year the company had just four employees, including the founder. But in 1985, Wimmer happened upon an idea that would propel the company into a new area and help to discover its true identity. The idea was to create a hydraulic quick coupler that would relieve operators of the necessity to leave the cab to change the work tools. At the time mechanical couplers designed by Toni Verachtert were common, but they still required the operator to get out of the cab and do a fair amount of manual work. Automatic devices did not exist, and that was the niche Wimmer plunged into. That was the birth of the A-Lock concept that would define Wimmer’s future for years to come. Business skyrocketed, and the company moved into new bigger premises in Thalgau and took on another 30 personnel.

Golden period The late 1980s and 1990s were a boom time for Wimmer. The A-Lock concept proved a tremendous success, on the back of which the company grew rapidly. In 1989, Wimmer branched out by registering a daughter company Wimmer Felstechnik, whose products included tunnelling equipment and demolition attachments. Four years later, Wimmer had built up a new manufacturing facility in the Czech Republic. Originally called Budwqeis Felstechnik, it was later renamed Wimmer International CZ. In the mid-1980s, Wimmer set its sights on the North American market. The company opened a sales office in Montreal, Canada in 1986, which became Wimmer’s operational base on the East Coast.

The Oilmatic era

The founder, Alois Wimmer.

As the new millennium dawned, Wimmer kept on developing at a breathtaking speed. In 2001, the manufacturer expanded its facilities in Thalgau and built a training centre for employees, customers and dealers. 2004 saw another milestone for Wimmer, when it developed the A-Lock Oilmatic, a fully automatic quick-coupling system with the tool recognition option. The company also built a new hall on its premises in Thalgau for rented equipment and a service department. The following year the company expanded its manufacturing facility in Budweis, doubling the capacity of the Czech plant. In 2006 Wimmer won an award for the best family-owned employer in the Salzburg area. Although affected, just like anybody else, by the 2008-09 recession, Wimmer managed to keep all the staff and eventually finished the decade on a high note by launching the next generation of fully automatic devices Oilmaxx, and developing a range of tilt and rotating units for excavators the Tiltator.

Father and son The demolition industry is still relatively young, with most companies going through their first generational change. Interestingly, if founding fathers more often than not tend to be inventors and engineers, their sons and daughters are usually trained as managers and business administrators. It is only Left: The Wimmer team in early days. Sitting on Alois Wimmer’s lap is his son and the other CEO in the future Andreas Wimmer.

Although quick couplers are the product that Wimmer is most known for, its range of solutions is far from being limited by it. Wimmer is a company that can solve any of its customers’ problems, and to be able to do this, a supplier must have a full range of tools available. As far as demolition and recycling is concerned, Wimmer offers attachments for primary and secondary applications, including hydraulic breakers, shears and grapples. Demolition tools are manufactured at the Thalgau facility and excavator buckets and tilt and rotating units, are made in the Czech Republic. Wimmer currently has 96 employees, of which 65 are engaged in production. Since customized and tailor-made products account for a significant part of the Wimmer catalogue, the company keeps a relatively big research and development department of six engineers. A brainchild of Alois Wimmer, the department has been under the founder’s supervision since day one. The average turnover oscillates at some EUR14M/year, with export accounting for around 45%. However, in the demolition attachment business, the situation is reverse with 55% of the output going for export, while the remaining 45% is sold domestically. As Wimmer products are already well known in all German-speaking countries, France, the UK and North America, the company has now set a goal to make the Wimmer brand recognisable beyond these markets. It might prove difficult in some countries, because Wimmer products are not cheap. In line with its motto “quality without compromise”, the manufacturer uses only high-quality parts and components for its attachments, and the resulting product is a durable and high-performing tool with an accordingly high price tag. But as Andreas Wimmer explains, “You can compare our products to a Savile Row suit. It might be expensive, but it is going to suit you on any occasion.”

Cape Town tackles rubble dumping The problem of illegal dumping by small demolition operators has resulted in Cape Town adopting a zero rate for clean builders’ rubble, which became effective on 1 July 2013. Clean builders’ rubble disposed of at council facilities is now free, subject to some individual site limitations and a general cap in vehicle carrying capacity of 1.5t. Jessica Hannah reports. Meanwhile, there has been challenges to work out an incentive scheme for companies that recycle building rubble. “When undertaking a demolition the company makes every effort to be environment-friendly,” says Ross Demolition owner Robert Ross. “Many building projects apply to be ‘Green’ with strict environmental rules to adhere to, including in the demolition phase.” Generally the mainstream South African demolition industry makes every effort to recycle as much of a building or structure as possible. There are outlets where recoverable material is sold, concrete is crushed for reuse as sub-base or aggregate. However, environmental efforts have also increased costs as strict controls have to be kept in place, additional staff employed and environmentalist fees are costly. Ross says that, on the other hand, it has become a way of life. He believes that there still needs to be a huge incentive programme as a company that is environmentally friendly, as far as is possible, is still paying exorbitant fees to do so. Draco Demolition managing member, Teddy Habib, adds that the accent these days is on ‘green’ demolition. “There are no green rules or regulations regarding demolition at the moment, but this will come, and by adopting these practices on everything we do, we aim to be fully compliant before this becomes a legal requirement,” said Habib.

Illegal Dumping: Waste disposal has been increased drastically rendering many demolition projects unsustainable, and leading to a scourge of illegal dumping.

Brokk establishes sales company in Switzerland Brokk, the world’s leading manufacturer of remote controlled demolition machines, strengthens its presence in Switzerland by establishing a new subsidiary, Brokk Switzerland. Brokk makes this long- term investment in the Swiss market after many years of partnering with a local distributor. Switzerland is a market with a long and successful Brokk history. The introduction of the Brokk remotely controlled demolition concept in Switzerland dates all the way back to the 1980s, and it has since continued to be a leading edge Brokk market. The establishment of Brokk Switzerland represents the twelfth subsidiary that Brokk has established or acquired in recent years, and is yet another proof of Brokk’s longterm commitment to its customers around the world. “We are now making an important strategic investment in the Swiss market. Our Swiss customers’ high demands on both the machines and the after-market service makes for a very good fit with Brokk’s values and how we operate. Consequently, we see a great potential for long-term growth and continued successful co-operation”, said Brokk Group Chief Executive Officer Martin Krupicka. Brokk Switzerland will focus on the sales and service of Brokk machines and equipment in the Swiss market. Operation of Brokk Switzerland started in September, when Brokk takes over the operation from its current partner in the market. Dieter Kaupp has been appointed managing director of Brokk Switzerland. Kaupp was previously leading the Brokk business at Mertec, as head of the Machinery business unit. “Our experienced team in Switzerland look forward to continue to provide our customers with the same high level of service they are used to”, said Kaupp.

South African legislation lagging behind Europe PDi continues its review of the South African demolition industry. Jessica Hannah reports. Despite excelling in areas such as mining and construction, South Africa is not on a par with its European counterparts when it comes to demolition, which is such a key driver of the African demolition sector, with South Africa as the leader in the field.

World’s changing but not South Africa Atlas Copco Construction Tools Division business line manager Neville Stewart, based in Johannesburg, believes that it lags behind international trends and legislation, choosing to continue with traditional methods of demolition while the world changes. Demolition remains an exercise of excavators with hammers, generally coupled with manual labour. This accounts for smaller projects, whilst larger undertakings, in the mining sector for instance, are most commonly drill and blast. “There

have really only been improvements in existing technology in the silent demolition and power demolition tools, but no new methods,” said Stewart. “Demolition will grow as buildings age in South Africa, which has relatively young structures not yet ready for demolition. As space becomes an issue, methods will most likely change, leading to demolition becoming more of a requirement to make way for more residential and commercial space.”

support. This is a particularly significant problem in remote areas of South Africa and in deeper parts of the continent as a whole where there are opportunities in infrastructure development. The latter is a problem to be addressed as South African companies looking across borders to ply their trade. “South Africa needs to look at greener demolition machinery and at how the construction, mining and demolition industry is dealing with sustainability and the impact that industry has on the future”, said Stewart.“The carbon tax doesn’t seem to have affected the demolition industry. It is paid ac-

cording to motor size and emissions at the time of purchase. What happens when machinery ages or is not maintained well? Efficiency of attachments can also affect fuel usage and thus emissions.”

Emission and noise levels might become the key Stewart believes that emissions and noise levels will determine future demolition methods. These are important design considerations in major markets already and South African developed machinery will have to follow suit. However, he says that we will have to wait a few years for that to happen.

Lack of technicians and service Another industry challenge is to maintain and service equipment, as well as produce skilled employees to operate and maintain new machinery to optimum efficiency. This skills shortage is also increasing labour costs, as good technicians become a rarity. The industry must also gear to provide operational

Wimmer helping in the alps The Austrian village of Schladming is a ski centre, which intends to invest to secure its future interest in tourism. The aerial cable car to the top of the ‘Hochwurzen’ will be renewed. Each car will be able to carry 10 passengers and have a capacity of 2,500 people/h.

But before a start can be made on the new cable car system all the buildings and installations for the old system have to be removed. For this kind of job contractors could opt for demolition attachments from Wimmer Felstechnik

in Thalgau. The Topcut demolition shears are considered to be a favourite and are available in four sizes covering carriers from 16t to 75t. During 15 years of research and development for Wimmer Topcuts many improvements have

been achieved. Five different jaws have been developed for various applications and can be exchanged by customers. A speed valve was installed to cater for an accelerated jaw closing when there is no resistance, which contributes to

a higher working speed. Topcut has a reputation for reliability and efficiency and there is the possibility for contractors to rent Topcut shears from Wimmer for special jobs.

HTC grinding technology in Swedish research project In Sweden Mistra Innovation has awarded a grant of SEK4M (EUR406,000) to HTC for its project Via Futura with the aim of describing the environmental and financial effects of using the manufacturer’s grinding technology on asphalt roadways in Sweden. The project is being run by HTC Sweden together with the Swedish National Road and Transport Research Institute, Linköping University, the Swedish Transport Administration, Svevia and Projektengagemang. An earlier pilot project showed that grinding considerably reduces noise and rolling resistance. Uneven road surfaces generate negative effects in the form of noise inside and outside vehicles, as well as by increasing the rolling resistance of the wheels, which in turn leads to increased fuel consumption. Another undesirable effect of worn road surfaces is the increase in breathable particles. A pilot project on one of Sweden’s busiest, the E4, showed that grinding the surface reduced noise by 2.2dB(A) and reduced

the rolling resistance by between 4% and 7%, resulting in a reduction in fuel consumption of 2%. “At HTC we see the application of HTC’s tried and tested grinding technology to surfaces other than stone and concrete floors as very exciting,” said HTC business area manager Per Sandström. “HTC has been developing this technology for many years and we hope this project will confirm what we believe our method increases travel comfort, as well as saving both the environment and the taxes spent on repairing the infrastructure.” HTC estimates that the grinding method could lengthen the service life of a road surface by approximately 20% to 50%, which would be a major cost saving. Grinding is a relatively fast process and it can be done either across the entire roadway or just along parts of it. Determining which of these is the optimum procedure will also be one of the aspects studied in the project, which is expected to be completed in December 2015.

Although Bauma broke visitor records, it fell short of a record for launching new products. In the wheel loader sector, most manufacturers just spruced up the machines previously shown at Intermat a year earlier. But, given the life cycle of a wheel loader, these machines may well be regarded as new. PDi’s Andrei Bushmarin reports. Emission regulations exert a major influence on the development of off-road construction vehicles. As they get increasingly tighter, engineers are forced to find ways to achieve an optimum balance between the power of an engine and the quality of the exhaust gas it generates. Currently there are two methods commonly used to reduce exhaust emissions. These are selective catalytic reaction and diesel particulate filter. Each has its pros and cons, but both effectively serve their purpose.

SCR vs. DPF Selective catalytic reaction turns nitrogen oxides in exhaust fumes into nitrogen and water. This method is used in the engines that power the latest New Holland, Case and Caterpillar wheel loaders. The Cat988K is equipped with the Cat C18 ACERT engine that meets the Tier 4 Final/Stage IV standard. It features electronic fuel control, ensuring optimum performance and throttle response and delivering up to 20% greater fuel efficiency, compared with its predecessor 988H, the company claims. Additional fuel savings accrue with the Cat988K Eco mode, engine idle shutdown system, and engine idle kick down/automatic resume system. The Case521F and Case621F wheel loaders come complete with common rail engines, which also use SCR with diesel exhaust fluid to meet the Tier4 interim standard. Operators can choose from the four working modes of maximum, economy, normal and automatic to fine tune the machine performance to a specific application. Volvo CE prefers to install diesel particulate filters in its wheel loaders. The diesel particulate filter is a device that retains up to 90% of soot and diesel particulate matter. All Volvo small and mid-range models are fitted with turbocharged diesel engines, which feature cooled gas recirculation and a DPF with active regeneration.

Cat988K: a perfect loading tool The Cat988K is one of the few wheel loaders that were premiered at Bauma. The 50t model features redesigned

46 PDi • Issue 4 • July - August 2013

loader linkage, drive train modifications, redesigned cab and enhancements in safety and serviceability. The Z-bar linkage has replaced the mono-boom construction of the previous Cat988H to enhance the 988K’s versatility in small quarries and underground applications. The new cab is equipped with Cat’s next generation vital information management system that informs the operator in real time of fuel consumption and efficiency through an interactive touch screen. In-cab sound levels are reduced to 71.1dB(A), down from 74.2dB(A) in the Cat988H, and the cab temperature control system is automatic and continuously variable. A remote panel houses a stairway light switch, engine shutdown switch, and lockouts for the transmission and engine starter. A second panel provides access to the battery disconnect switch and a jump-start receptacle. A rear view camera system provides images to the in-cab monitor. Routine maintenance points, including hydraulic pressure taps and oil sampling ports, are easily accessed. The 988K will be available from August.

New compact from Wacker Neuson Germany-based Wacker Neuson used Bauma to showcase the WL 20, the smallest wheel loader in its nine model range. With a height of 2.19m and a width of 1.08m, the new wheel loader is very handy on jobs in confined areas and inside buildings. An articulated swivel joint allows the machine to maintain contact with the ground with all four wheels, even on uneven terrain. As the front and rear ends can oscillate independently of each other, the wheels always have maximum

traction. With an operating weight of 2t, the loader has a tipping load of 1.24t. The shovel capacity with a standard bucket is 0.2m?. The WL20 is available with a fold-down canopy roof.

The Volvo 5 First presented at Intermat, the L45G, L50G, L60G, L70G and L90G, are the latest additions to Volvo CE’s small and mid-size ranges of wheel loaders. Fitting in the 9t-10t weight class, the smaller L45G and L50G boast versatility and performance of larger machines. The machines feature Volvo’s TP Linkage, ensuring high breakout force and parallel movement throughout the entire lifting range. This combination gives high tilt-back torque and lifting power, while the progressive lift helps retain loose bucket material and minimises disturbing the load when lifting

Hitachi wheels out a new mid-size model Hitachi Construction Machinery (Europe) has extended its mid-range of wheel loaders. Presented at Bauma, the new ZW220-5 comes complete with a 7.8-litre six-cylinder water-cooled turbo engine, enabling a powerful digging performance and high travel speeds. A newly-designed clutch cut-off system allows for smooth operation when it is loading. The machine has two work modes. In the standard mode, the engine speed is controlled, which allows for smooth and efficient acceleration during loading, regular operations and travelling on level terrain. The P mode is useful when greater traction force is required for heavy-duty excavation and travelling uphill. The wheel loader features a new hydraulic circuit, which facilitates the combined operation of the bucket and lift arm for loading, and prioritises the use of the bucket for unloading. Visibility is boosted thanks to a pillar-less windshield and large sun visor. The counterweight is also visible from both sides of the machine. The shift-up delay to third gear makes it safer for the loader to operate in confined spaces, because it can perform excavating and unloading tasks more safely in first and second gear. The cab is more spacious than the previous model, because the heated air-suspension seat can slide further back, providing more legroom. The tilting telescopic pop-up steering column has also been repositioned to create additional space.

pallets. The combination of stable load and high-reach of the linkage design allows dumping into high-sided trucks. The bigger L60G, L70G and L90G are complete with Volvo’s six-litre, six-cylinder turbocharged V-ACT diesel engine, providing high torque at low engine speeds. The new engine capabilities are matched to those of drive train, hydraulics and lifting systems. Thanks to high-capacity axial piston pumps with variable flow, the working hydraulic pressure has been increased from 260bar to 310bar, ensuring superior control of the load and attachments as well as higher breakout forces and faster lift and tilt functions. Transmissions feature Volvo’s fully automatic power shift concept, which ensures that the loader always operates in the right gear by sensing engine and travel speed, kick-down, engine braking and other factors. Offering operators a choice of four gearshifting programs, APS results in more efficient work cycles with lower fuel consumption and wear.

RECYCLING

inside talk

The Master o inside talk

In this latest Inside Talk, we feature Gerald Hanisch, the chief executive officer of the Austria-based company Rubble Master. Hanisch spoke about the nuts and bolts of the recycling industry with PDi’s Andrei Bushmarin.

First RM model on the market.

It is fair to call Austria the recycling centre of Europe as it has more manufacturers of mobile recycling equipment per capita than any other country in Europe. But to be precise, it is the city of Linz and the neighbouring towns and villages that constitute the real capital of mobile recycling. It was in Linz that Hanisch started his company 20 years ago.

Tough beginning Hanisch, a graduate in mechanical engineering from the LiTec College Linz, initially got involved with mobile recycling when working for a company based in Linz. He did not stay long as he was never a nine-to-five man, content to just perform his duties. An entrepreneur by nature, he detected a gap in a rather tight-knit recycling market that nobody had yet filled and went for it. That gap was compact mobile recyclers for inner city jobs. He pictured machines that would be nimble, easy-to-operate and affordable. In 1991 he left his job and teamed up with a colleague to form a new company called HMH, which had a difficult start. The early 1990s were a time when the e-commerce bubble burst, and getting finance for a start-up project was a major obstacle. Eventually, a loan from the government of Linz helped overcome that. The prototype machine was unveiled in 1993, and, later in the year, the fledgling manufacturer supplied its first compact recycler RM 50 to the Austrian customer.

International ambitions from the start In the early days the company only had three employees, but it didn’t deter Hanisch from prioritising the international market. But, as a new company HMH was facing a big challenge of having to convince buyers of the advantages of its machinery. Under 30t recyclers were unheard of at the time, and it took

the market a while to recognise their potential. Germany, as usual, lead the way by becoming the first country to buy an HMH machine. The UK, Denmark and a number of Eastern European states soon followed. But a truly global recognition came to HMH in the late 1990s with the development of its mobile crushers RM 60 and RM 80. The latter became a best seller, which allowed the company to considerably expand its international sales network. In the early 2000s, the Austrian manufacturer conceived and realised a concept of environmentally friendly recycling dubbed RM Enviro. It called for the use of integrated soundproofing and dust suppression systems at critical points of the recycler and a hybrid diesel-electric transmission. It was also around that time that the Austrian company penetrated the US market with its proven crushers and a newly designed range of screens. An office was set up in Memphis, Tennessee to run the North American operation.

Birth of the GO! concept The 2006-07 construction boom allowed HMH to reach new heights. It added South Africa to the list of conquered markets, opened up an office in the UK and began expanding its headquarters in Linz. It was then and there that the GO! concept was born. Sim-

of Rubble! plicity of operation had always been a trademark quality of every HMH machine, and the GO! range became the ultimate realisation of that principle. With a GO! crusher, all the operator has to do is push the button and start working. No setting-up or extra tuning is necessary. The GO! concept was a second major break-through for HMH after the RM 80 success, which unfortunately was marred by the onset of the global recession. To weather the storm, the company, which was rebranded in 2008 as Rubble Master HMH, had to tighten its belt and even lay off some staff. Hanisch remembers that letting those employees go was one of the hardest decisions he has ever had to take as a manager. But once the worst was over most of the people that were laid-off were re-employed.

New dawn In 2010, things were on the up again. In an attempt to replicate the business model that worked so well in Austria, the manufacturer registered a sales office in Switzerland and went through yet another rebranding procedure. The reasoning behind rebranding was to show the market that the company was ready to move on and try its hand in new business areas, the extractive industry being one example. The renamed RM Compact Crushing continues to expand its range of mobile crushers and screeners, to which a model of stacker has been recently added. The MTS 2010 stacker was first unveiled at Bauma, along with a range of crushers, featuring the anew RM TWO-GO! hybrid

technology. These crushers come complete with both diesel engine drive and an electric motor.

Gerald Hanisch, CEO of Rubble Master.

Spokesman for the customer The cornerstone of Hanisch’s business philosophy is that he, as the chief executive officer, must maintain close contact with his customers, picking up their ideas and translating them into new and better solutions. He himself calls it ‘being a spokesman for the customer’. Being able to think on your feet and react immediately to ever-shortening industry cycles is another important characteristic of a successful manager, believes Hanisch. He has built his business around three core principles of product development that should never pause, elaborate design of the machines and clever marketing. RM machines are now sold in over 90 countries, and the list keeps growing as the company expands its dealer network. The forth coming Bauma Africa, where Rubble Master will have a large stand in the outdoor area, will provide an ideal opportunity to do just that.

US road construction to increase by 3.5% through 2013

During the five years to 2013, the US road construction industry grew at an average annual rate of 2.8% to $49.7bn (EUR37.4bn). In 2013, revenue is expected to increase 3.5% due to increases in government funding for highway projects. While revenue has grown, US highway contractors were not immune to the recession’s negative effects. Falling demand from the private sector and decreased state and local government funding have drastically increased competition for federally funded projects. As competition intensifies, operators are increasingly competing for projects on price, consequently profit margins are suffering. In the short term, there will be a small market improvement due to certainty in funding because of the new federal highway bill (MAP-21) passed in July 2012. The legislation means that states are more likely to start and fund medium scale projects with funding levels assured through

2014. However, long-term market prospects remain difficult as both state and federal governments refuse to increase their respective gas taxes or implement other funding schemes. Without expanded user-based fees, states will have to use more and more of existing funding to maintain existing infrastructure, and make more use of alternative financing schemes such as public-private partnerships, state infrastructure banks and tolling to finance new construction. This will limit growth through the decade for all segments of the road construction market. The industry is expected to return to moderate growth in 2013, with the new Surface Transportation Extension Act of 2012. Additionally the Moving Ahead for Progress in the 21st Century Act (MAP-21) into law in July 2012 will fund surface transportation programmes at more than $105bn/year (EUR79bn) for the 2013 and 2014 fiscal years.

LEHNHOFF AT THE ‘ Automatic quick couplers are now an integral part of almost every demolition contractor’s arsenal. Thanks to these simple devices, the changing of work tools and attachments can be made in a matter of seconds. Currently only a few companies make them, including Lehnhoff Hartstahl in Germany. PDi’s Andrei Bushmarin reports.

In July 1960 Ernst Günter Lehnhoff founded the company Metallbearbeitung Steinbach in the spa town of Baden-Baden repairing gears. Two years later the company exhibited at Bauma for the very first time, which influenced a fundamental change to the company’s strategy.

Focus on excavator attachments Gone were the gears and together with a change of name to Lehnhoff Hartstahl, the company refocused on manufacturing tooth systems for backhoe and shovel buckets. That was a groundbreaking decision, which, to a large degree, shaped Lehnhoff into the producer it is now. The late 1960s was a momentous period for the German company. In 1967 it became one of the first manufacturers in the world to make excavator attachments from armoured steel. Just one year later Lehnhoff received an order from a customer to develop what would become the world’s first tilting bucket. Lehnhoff rose to the challenge and soon delivered the model, but never bothered to patent it. When Ernst Günter Lehnhoff passed away in 1980, his son Peter Alexander picked up the reigns. During the 1980s, Lehnhoff extended and expanded its range of attachments, which resulted in it being chosen the original equipment supplier for Komatsu Germany in 1984. But a pivotal moment Lehnhoff ’s fortunes came in 1989, when it devised its first

quick-coupling system for mini-excavators the Lehmatic MS03.

Quick couplers - a new direction Having designed the Lehmatic system, Lehnhoff realized it had struck a very rich vein, and lost no time in developing it. By 1992, the manufacturer was able to offer an extensive range of quick couplers for carriers ranging from 1t minis to 70t hydraulic excavators. Five years later, Lehnhoff delivered a first Lehmatic HS100 quick coupler for a 100t demolition excavator. Lehmatic couplers proved very popular and by 2001 around 30,000 units had been sold worldwide. Part of the profit was reinvested in upgrading production facilities with new equipment, like laser cutting stations, welding robots and computer numerically controlled processing centres. Peter Alexander Lehnhoff, the current CEO of the Lehnhoff company.

Development of Variolock There are a few types of quick couplers, but it is fully au-

tomatic devices that really make a difference for excavator operators and owners. Using such a coupler, operators can change between various attachments within seconds while staying in the cab, which increases productivity but also improves their safety. Another benefit of an automatic quick coupler is that all hydraulic lines are routed inside the system, which prevents any oil leakages. Competition is still limited in this sector, with only a few companies dominating the global market. Lehnhoff began working on its own fully automatic coupler in 2004, and three years later unveiled the prototype at Bauma. The new device named Variolock was based on the proven Lehmatic system and boasted high rates of reliability. According to Lehnhoff, some Variolocks have racked up 2,000h without a single incident of malfunction.

Hard work ethics Putting in an honest day’s work is not difficult to the Lehnhoff staff. The company has a strong work ethic and even named its canteen ‘Hard Work Café’. With 170 employees, Lehnhoff is a mid-size company and 120 work in production, 30 perform the sales and administration tasks and another 20 work on research and development. The large Research & Development department is a necessity, because

Lehnhoff designs a lot of one-off products. The BadenBaden facility covers 20,000m2 and houses equipment for the production of all types of quick couplers and excavator attachments. To demonstrate the capabilities of Lehnhoff tools to potential customers, the company is building a demonstration area next to the main building. This will be big enough to accommodate five 3.5t to 23t excavators that will be used to demonstrate the advantages of Lehnhoff quick couplers and various attachments. The range of attachments is constantly growing and Lehnhoff has been finalising a new range of sorting grapples, which will be launched in Issue 4 • July - August 2013 •

Servitécnica improved the production The Brazilian specialist concrete cutting contractor Servitécnica, has carried out a demanding job at the Fibria Celulose paper production plant in Aracruz, once the biggest paper mill in the world. Servitéchnica, based in Belo Horizonte in the state of Minas Gerais, visited the site and produced a cutting plan for the job. The contractor drew up a schedule of work that projected completion in just four days. This met the client’s expectations and the project was approved. Servitéchnica has considerable experience of this kind of job and has worked with concrete sawing and drilling as well as demolition for more than 20 years. It is one of the bigger concrete cutting companies in Brazil and has also a subsidiary for remotely controlled demolition called Demoloção Remota. Besides its head office and workshop in Belo Horizonte. Servitécnica also has branch offices in Rio de Janeiro, Salvador and Vitória.

Scheduled cleaning stops In the Fibria Celulose plant production has to be stopped to make scheduled shutdowns for removing solid material from the effluent mixing tank resulting from the manufacturing processes. This is a deposit on the bottom of four tanks, each divided into three levels. Maintenance access to the four tanks is gained through 600mm x 600mm openings in concrete slabs, making cleaning operations extremely slow. Fibria Celulose, contracted Servitecnica to remove the 12 heavily reinforced concrete slabs measuring 3.4m x 2.6m, and each weighing 4.4t. At the same time the tanks would remain in operation and the company had to ensure that the process adopted would not result in any solid material falling into the tanks.

Hot and smelly Due to the irregularities in the slabs and the impossibility of gaining access to their undersides it was decided to cut them using wall saws equipped with 800mm diameter blades. Two wall saws and two electro hydraulic 20kW Tyrolit units were used simultaneously to cut and remove the slabs in daily shifts of 12 hours. When removing the slabs, to make the interior of the tanks visible, the work was very hot due to the high temperature of the very smelly liquid in the mixing tanks. Each concrete slab was hoisted at four points and removed using a crane. The job was finished in four days, as to the schedule, without any accident or safety

incident. On completion the factory staff congratulated Servitécnica for the quality and speed of their work. Removing the effluent mixing tank covers, will allow the removal of solid residues from the interior of the tanks to be mechanised, resulting in shorter factory shutdowns and improved productivity.

CSDA’s new electric safety video In the US the Concrete Sawing and Drilling Association has released its new Electrical Safety video. The aim of this video is to spark interest in electrical safety in the industry and make employees aware of current safety procedures. According to the Bureau of Labour Statistics, electrocutions accounted for over 170 fatal occupational injuries in 2011 across the US. In addition, the Occupational Safety and Health Administration issued almost 3,500 citations for breaches of its electrical standards between 2011 and 2012. Therefore, it should come as no shock that the CSDA has produced a video to help contractors avoid and manage electrical hazards on jobsites. Electrical Safety is the latest in a series of training and certification resources from CSDA. Since its launch in 1995, the CSDA Training Programme has expanded to offer both handson and online classes totalling 34 products. More than 3,700 classes have been completed to date, and CSDA has sold over 1,500 hard copy safety videos to the industry. This new video follows on from previous guidance on electrical safety included in the association’s 230 page Safety Manual, its Safety Handbook and several of its Toolbox Safety Tips. In addition, through its ongoing Alliance partnership with the OSHA, CSDA released an OSHA Alliance Best Practice on electrical safety in 2010. This document is available to download from the CSDA Website. “This is an important video for contractors who operate electric powered equipment and for employees working on jobsites with electrical hazards, which is almost everyone,” says Dan Cowperthwait from Atlantic Concrete Cutting and CSDA safety committee chairman. “Following the guidance provided in Electrical Safety could be the difference between life and death.” Electricity is widely recognised as a serious workplace hazard and employees can be exposed to electric shocks, burns, fires and explosions on sites. Like most industries, the concrete demolition and renovation industry is experiencing an increase in electric powered equipment. More than ever before, it is crucial that employees be trained in hazard recognition and safety procedures related to electricity. The 20min Electrical Safety video is available online via www.csdatraining.com or in DVD format for employers to purchase and conduct electrical safety training.

Train more and save with CSDA As the US Concrete Sawing and Drilling Association’s training programme approaches a milestone of 4,000 graduates, the association is now offering a range of discounts up to $1,000

(EUR750)/student. Due to an increasing interest in its range of hands-on and classroom courses, the CSDA has created a pricing structure for those who want to train two or more employees at once. Under the new pricing structure, an employer could send three employees to a two-day training or certification class and the savings would equate to almost 25% of the standard price. These savings can increase further if the employer registers more students, but the association is aware that not all companies can afford to have multiple employees off jobsites or out of the shop or office. “We had several contractors express an interest in sending two or more employees to training classes but the costs associated with registration, travel and accommodation quickly add up,” said CSDA training committee chairman Kevin Warnecke. “By offering tiered prices, we hope to present contractors with significant discounts that lower overall costs and allow more employees to attend and receive training. This is a great deal for both the employer and employee.” Tiered pricing applies to all future two-day hands-on and classroom courses hosted by CSDA and its training partners. Classes held at World of Concrete are excluded from the new pricing structure, but will remain at the competitive price of $785 (EUR590)/student. “Training has always been a worthwhile investment for any business and we have seen so many companies benefit from our handson and online classes”, said CSDA executive director Patrick O’Brien. “We want our classes to be an affordable investment for our smaller member companies and offer discounts to those larger companies who want to train several employees together.” The association launched its training programme in 1995, which now consists of 34 hands-on classes and online sessions. More than 3,700 classes have been completed to date, and CSDA has sold over 1,500 hard copy safety and training videos to the industry.

ing and education in the demolition process to oversee the work being performed by a competent demolition contractor,” said NDA executive director Michael R. Taylor. “The NDA strongly recommends the use of a professional engineer when an association member is confronted with a challenging structural issue on a project site. However, few, if any, architects or professional engineers, unless they have worked in the demolition industry, have the training or expertise to knowledgeably comment on the work plans of a demolition project.” The hearing was precipitated by a demolition accident in June in Philadelphia that killed six people. The NDA was invited to provide testimony because it represents more than 800 firms involved in the approximately $5bn (EUR5.8bn) demolition industry. Taylor pointed out in his testimony that according to statistics compiled by the US Bureau of Labour Statistics and Occupational Safety and Health Administration, the seemingly dangerous industry is in fact overwhelmingly safe, with only one workplace fatality occurring every one million man-??hours. “It seems a wise idea to the NDA to include a system of review of construction codes, administrators, and third party agencies charged with enforcement and administration of laws,” said Taylor. He noted that under OSHA standard 29 CFR 1926.850, a written engineering survey is prepared by a competent person to determine a structure’s condition and the possibility of unplanned collapse of any portion of the structure. In the testimony, Taylor also addressed the proposed requirement for at least $1M (EUR755,000) in liability insurance could have an economic impact on certain smaller demolition projects. “For companies new to the demolition industry, these additional costs could have an impact on getting started in the industry,” said Taylor. A full copy of Taylor’s testimony is available at http://www.demolitionassociation.com/ OURINDUSTRY/DisasterResponse/tabid/265/ Default.aspx.

Las Vegas for NDA NDA testifies on convention 2014 Philadelphia building In the US the National Demolition Association’s collapse 41st annual convention will be held at the In testimony before the Pennsylvania House Committee on Urban Affairs concerning legislation meant to change safety requirements for city demolition projects, the National Demolition Association executive director supported many elements of the law, but took issue with requirements on project oversight. Specifically, the bill would require all demolition plans for commercial structures in Class One Cities in the Commonwealth to be reviewed by a licensed architect or professional engineer. “While in no way impugning the value of these professions, they simply lack the train-
