We’re Back! Welcome to the latest edition of the Demolition magazine. Did you miss us? We must start with an apology. Due to circumstances beyond our control, we temporarily lost our advertising manager late last year and, since the adverts pay for everything else, we were unable to publish the previous two editions. However, those issues have been resolved and, as you can plainly see, we are back…bigger, better, and brasher than ever before. A considerable amount of water has flowed beneath demolition’s bridge since the last edition of the magazine flopped onto your doorstep. We have seen names like Masterton and Hunter Demolition erased from the industry landscape; we have seen an NFDC president go and another one arrive; and we have seen an increasingly bold recovery from the dark days of recession. We have tried to reflect that within the pages that follow, and within the revised format of the magazine which – as you can see – has eschewed the familiar black livery in favour of something more in keeping with current times.

And the changes don’t stop there. Some of our tried and tested items – QuickFire, Demolition TV and App Happy – have given way to make room for a greater focus on actual demolition work, although they might be back again in the future. But perhaps the biggest change is your method of consumption. Partly to do our bit for the environment and partly to reduce unnecessary print and postage costs, we have switched to a (virtually) electronic-only format. We would rather invest the money we used to spend on paper and stamps on bringing you more and better items to read and videos to view. This change will also allow you to read it online, via a new iPhone and iPad app unless you want to pay for a printed paper version (subscription details at the foot of Page 3). We’re sorry it’s taken so long to get our house in order. But rest assured, normal service has been resumed, with some added extras thrown in by way of an apology. Mark Anthony

and recycling sectors. Some of the leading producers of specialist attachments, crushing and screening equipment will be jostling for position within the SCDZ, many of them displaying equipment making its PlantworX debut.

If you’re looking to find ALL the hottest demolition kit on the market this year, there is only ONE exhibition for you and that’s PlantworX 2015. Mark Anthony looks ahead to the show and at the Demolition magazine-sponsored Site Clearance and Demolition Zone in particular.

If there is one demolition name that is synonymous with innovation then that name is Brokk whose remote controlled machines have removed man from potential harm and made demolition significantly safer as a result. The company is bringing its robot army to PlantworX with a comprehensive display of remote controlled demolition might comprising the Brokk 60, 100, 160, 260 and 400 models. The versatility of these demolition robots is further enhanced by a full range of mounted and handheld attachments including concrete crushers, steel shears and concrete splitters.

Quick to embrace new developments to make work safer, cleaner and more productive, the demolition and site clearance sector is one of the most innovative in the construction equipment sphere, as evidenced by its representation within the PlantworX Awards. PlantworX 2015 provides an ideal shop window through which to view the latest developments in this fast-moving sector.

Also at the cutting edge of innovation is Worsley Plant, recipient of a highly commended in the engineering category of the PlantworX Awards

Although the carriers – excavators, mini excavators and skid steer loaders – will be dotted across the entire PlantworX site, the Site Clearance and Demolition Zone (SCDZ) should be the first stop for anyone in the demolition

stuff for the Lehnhoff Hartstahl manufactured Variolock Quick Coupler System. Designed for specialist sectors like demolition and recycling, the Variolock system ensures that changing attachments is effortless, safe and fast. In addition to ensuring faster attachment changes, the Variolock system reduces contamination of the hydraulic system and delivers less back pressure and lower fuel consumption. The Variolock range is an ideal match for Worsley Plant’s range of high-quality attachments such as crushing and screening buckets, grabs, shears and pulverisers and can work with other similar products on the market.

Making its debut at PlantworX 2015 is CMB International which is based within spitting distance of the new Bruntingthorpe show ground. The company will be showing off its RC150 trailer-mounted jaw crusher that features a single toggle jaw crusher and which is powered by an emissions-compliant Hatz diesel engine delivering 28 kW of power. Despite its compact dimensions and light weight – the unit weighs just 3,000 kg including the trailer – the RC150 rubble crusher is remarkably productive, with a crusher throughput of up to 50 tonnes/hour that makes it ideally suited to plant ire and confined space, inner-city recycling applications.

stuff but with crushing performance of nearly 45 tonnes per hour. That is the equivalent nine skips worth of rubble converted into a saleable product in just an hour. Over on the CGCS Midlands stand, meanwhile, the company will be displaying a representative model from its PRONAR range of trammel screens. The MPB 18.47 unit, which weighs in at just under 13 tonnes, forms part of a threemodel range and is powered by a 62 kW Mitsubishi diesel engine. According to CGCS Midlands, the MPB 18.47 is suitable for soil, compost, municipal waste, coal, aggregate, and biomass applications and can be tailor-matched to customer requirements with round or square holes and different plate thicknesses. Equipment suitable for application in the site clearance and demolition sector will not be confined to the SCDZ, however. One of the most talked-about machines at the show is another aimed squarely at the demolition fraternity but which will be displayed outside the SCDZ.

Another PlantworX Awards winner, Wacker Neuson‘s smallest mini excavator – the 803 – is offered with a dual power option. In addition to the standard diesel engine, the unit can be connected to an external electro-hydraulic drive unit HPU8, allowing it to operate electrically and completely emission-free. If you’re involved in internal demolition or strip out applications, the Wacker Neuson 803 is a must-see. A familiar and popular name in demolition circles is ECY Haulmark which returns to PlantworX with an impressive and comprehensive display of attachment power. Taking centre stage will be the company’s range of FRD Furukawa hydraulic breakers. Of particular interest will be the FXJ mid-range that replaces the previous XP range. The FXJ range includes the FXJ135, FXJ275, FXJ375 and FXJ475 that are suitable for 12-55 tonne base machines and which benefit from a mono-block design with no through bolts. ECY will also be demonstrating the OilQuick automatic quick coupler system on the demonstration area. There are now over one hundred OilQuick units in operation around the UK, many with leading names in the demolition business such as AR Demolition and Armac.

The Heart of the Matter Today’s sophisticated construction, demolition and recycling machines have powerful hydraulic systems at their heart. As with a human it’s vital to keep the system in a healthy condition to maximise performance and reliability. In the same way that your doctor would check your temperature, blood pressure and carry out a blood test if you were ‘under the weather’ you can carry out a machine ‘health check’ with a few relatively simple tools. Hydraulic oil can be considered as the equivalent of blood in a human, its condition affects machine performance and reliability.

The hydraulic system is the beating heart of all construction equipment. Keeping that heart healthy is key to ensuring that equipment has a long and productive life. Demolition magazine reports.

Essential Tasks Hydraulic oil performs several essential tasks in modern construction equipment. Firstly, it provides fluid power, transferring the energy from the machine’s engine to the hydraulic components to operate the machine. In an excavator the engine driven pump provides a flow of hydraulic oil under pressure that is used operate the track motors, the slew motor, and hydraulic rams to operate the machine’s boom, dipper, and bucket. Secondly, it provides the required lubrication between component parts minimising wear. Thirdly, it provides a heat transfer function spreading heat throughout the system and providing the means to cool the system through the use of oil coolers. Hydraulic systems, in modern machines, operate at

stuff very high pressure, up to 450 bar, and under extremely close tolerances demanding regular monitoring of fluid cleanliness. Particle and water contamination are the most common hydraulic system problems both of which lead to increased wear and potential damage to the fine tolerances of pumps, valves, motors and cylinders. Essentially there are four tests that can be carried out to monitor the condition and performance of hydraulic oil and hence machine health. 1Oil temperature 2 Oil pressure 3 Oil flow rate 4 Oil contamination, water and particulates

Temperature Measurement Most modern machines are equipped with monitoring and diagnostic tools that are integrated into the machine’s engine management and hydraulic systems. High oil temperature is usually a sign of either low coolant or oil levels or blocked radiators or oil coolers. If all these are OK but oil temperature is too high there are several tools that can be used to accurately measure hydraulic oil temperature under different operating conditions.

If you suspect that a machine has lost performance and need to troubleshoot the hydraulic system there are a wide range of tools to help from simple analogue pressure gauges through digital pressure gauges to sophisticated flow turbines and digital data loggers.

Very accurate temperature sensors, with a working range from -50°C to 200°C, can be fixed in Minimess test points which can be fitted in any run of hose or pipe using standard hydraulic adaptors with the appropriate thread for the machine. (E.g. BSP for a JCB, JIC for Cat, Metric for continental European machines). An electronic data logger is used to read the electronic signal from the temperature sensor and convert it into meaningful data that can be recorded and analysed as part of the fault finding process.

Analogue flow Management A universal truth is that when troubleshooting hydraulic systems flow should be checked first followed by hydraulic pressure in a specified order of priority through different points of the system. The simplest way to accurately measure hydraulic flow is to mount a flowmeter into the hydraulic system at an appropriate point. Instruments like the Hydrapro 702 cost around £780 (including VAT) but

STUFF

make flow measurement a safe and practical proposition. The instrument has a stainless steel body, ¾ inch BSP ports and can work safely at up to 240 bar. It is an analogue instrument, which is non-electrical, making it both reliable and durable. It can be easily fitted into a run of hose or pipe using adaptors.

Digital Temperature, Flow & Pressure Measurement

Once installed the Hydrapro shows hydraulic flow up to 110 litres per minute, temperature to 116°C, and pressure up to 345 bar, adequate for even large excavators. An integral load valve allows the system to be put under load up to 414 bar, simulating a work cycle.

The ultimate solution is a digital 3 channel data logger and flow turbine kit. This sophisticated solution will set you back around £4,200 but will enable you to tackle any job. The 3 channel data logger enables comprehensive recording of data, with an internal memory capable of storing 1,000,000 readings, and analysis using a bespoke Windows based software package, Hydrcom 6.

The Hydrapro can also be used for setting-up a pipework kit and system for dipper mounted breakers and other hydraulic attachments.

A flow turbine unit RE4 is mounted securely in the hydraulic system using adaptors at a hose or pipe joint. The turbine unit measures flow, temperature and pressure and transmits digital data to the data logger in 3 channels. The unit provides a ‘real-time’ read out of the parameters being measured and records the data in the internal memory. The data is easily transferred to a PC via a standard USB port.

Analogue Pressure Management Checking hydraulic pressure in a hose run is comparably simple and relatively cheap (£120) analogue pressure test kits are good enough for a quick check. They are mounted into the hydraulic system using adaptors with the appropriate thread form for the machine. Analogue gauges show pressure but do not record data and they are not capable of showing pressure spikes for example.

Digital Pressure Management The next step in sophistication is to use a digital pressure gauge or kit. The advantages, over analogue gauges, are that they are much easier to read, they are more accurate and they can record minimum and maximum pressure. Digital pressure gauges can work at up to 600 bar. A kit with fittings costs around £440.

Many machines will already have pressure test points mounted on pumps or in the hydraulic circuit. It is safe and easy to fit pressure test points in a machine’s hydraulic circuit. The machine should have the engine off and hydraulic pressure in the system should be dissipated by operating the control levers. Pressure test points can be fitted for temporary use or as a permanent fixture. As long as they do not constrain the circuit’s hydraulic flow they do no harm. An adaptor and pressure test point can be placed at any hose or pipe junction. The hose/pipe joint is opened and the ‘T’ piece adaptor screwed into place. Adaptors are readily available in all the common thread forms including BSP, JIC, ORFS and metric. The ‘T’ piece is fitted with a Minimess pressure test point. Minimess test points provide a safe interface to the active hydraulic circuit. An analogue or digital pressure gauge is easily fitted to the Minimess test point using a gauge adaptor. Low cost pressure test kits provide all the components required. Minimess test points can also be used for taking oil samples.

Bucket Kryptonite

God created the Earth in six days. On the seventh day, he rested. On the eighth day, having seen his football team lose at home and having awoken with a near-terminal hangover, he was in a foul mood so he devised the ultimate test for excavator buckets. And lo, he created demolition.

Demolition is to excavator buckets what kryptonite is to Superman. If there are two things in the world that excavator buckets hate most, it is impact and abrasion; demolition delivers both â&#x20AC;&#x201C; quite literally â&#x20AC;&#x201C; by the bucketful.

Hidden rebar encased in jagged concrete grind, wear and eat away at buckets. And all the Hardox steel, ground engaging tools, reinforced teeth and cutting edges and enhanced operator care offers about as much long-term protection as a silk-lineed cloak affords a Matador. According to fabrications specialist Rich Holt, one of the key issues is that buckets are generally designed with digging in mind. They are manufactured to ease the flow of material in and out of the bucket with the minimum resistance. And that same lack of resistance tends to corral material – debris in the case of demolition – ensuring that the wear is contained and concentrated in the same place over and over again. The result is premature bucket wear and a hefty repair or replacement bill. “The front of the bucket is where all the wear and tear is

contained as, basically, this is where it strikes the material,” Rich Holt says. “Over time, this will wear, causing the bucket to lose its strength and, ultimately, to fail.”

In the Worn Zone Rich Holt, founder of Fabrications by Design, comes to buckets and demolition with a fresh pair of eyes. Relatively young, he openly admits that it was only a few short years ago that he thought that all excavators were called JCBs.

the way we do it is basically we heat the steel up, temp it, and then put the wire down in lots of different directions so it has more places to wear.”

Ad his first up-close encounter with a bucket was when he was offered the opportunity to actually work on one.

According to Holt, this approach is doubly effective. “By laying down the hard facing in these swirls and patterns, we are able to give the bucket greater protective coverage,” he explains. “In addition, the tattoo-style pattern helps to ensure that the material is dispersed and doesn’t follow the same path over and over again. This too helps reduce overall wear.” Rich Holt reports that, in addition to helping customers’ buckets last longer and reducing their owning and operating costs, there has been an unexpected benefit of his tattoo-style. “By the time a bucket leaves our premises, it is absolutely unique. Not only does this act as a deterrent against opportunist theft, it would also help trace the bucket’s original owner if one of our buckets was stolen.”

But that fresh perspective also allows a fresh and innovative approach. And rather than replicate the straight line bucket protection that is the stuff of tradition and received wisdom, the bucket protection provided by Holt and his team is characterised by an intricate and unique tribal tattoo aesthetic that looks freshly ripped from the bicep of a hipster with no imagination and hippy leanings. “What people used to do was weld rebar on or solid strips of hard facing wire.” Holt continues. “Our solution is basically putting hard facing wire down through a MIG welder, which is quick and cost effective.

A former office block built in the 1960’s was demolished over the May Bank Holiday weekend to minimise inconvenience to train users and other Coventonians. The demolition commenced at midnight on Friday 1 May and was due to be completed in 48 hours. The work was successfully executed and completed by Sunday afternoon and the access to the station was re-opened by 5pm on Sunday 3 May and 6 hours early. It is now possible to see the station. Residents, commuters and office workers were amazed this Tuesday morning to return to work to find that the whole office block had basically just disappeared.

managers, machine operators, and operatives everything came together with excellent results. The demolition was carried out by Solihull based Armac Demolition utilising several large high reach excavators. Some 4,000 tonnes of concrete was demolished using a progressive fragmentation method where by the concrete was “chewed down” using hydraulic attachments, this method avoided the use of hammers during night time hours to avoid noise and disruption to local residents and businesses.

The project took weeks of pre-planning and coordination with several key stake holders and logistically this could have proved to be very challenging, but with a team of highly skilled

The Big Picture A landmark demolition project in the centre of London’s movie land has put contractor John F. Hunt in the spotlight. But the company has risen to the challenge with an innovative, four-sided façade retention. Mark Anthony gets ready for his close-up. It is estimated that 37 million people pass through Leicester Square each year. Some are following their noses to M&M World where the sickly-sweet smell of chocolate alone is enough to swell the waistline. Some are heading for the nearby Covent Garden and its many restaurants, bars and hipster hangout delights. But most head to Leicester Square for the movies. Even though the technology of many of the square’s cinemas have long since been overtaken by out-of-town multiplexes and IMAXs, Leicester Square remains the capital’s movie central. The square hosts as many as three movie premieres each week, has hundreds of yards of red carpet on permanent standby, and its air is heady with the pungent whiff of p popcorn.

on site But the property requiring the attentions of John F. Hunt was the AA headquarters which was built progressively between 1923 and 1959 and which, as a result, comprised a hotchpotch of materials and construction methods. Furthermore, a pair of lift wells had been infilled during the 1970s. “Given the location and the need to retain all four facades, our process began with an extensive investigation to identify construction methods and materials, pockets of asbestos left behind after previous strips, and – of course – liaison with key stakeholders including Westminster City Council, the Heart of London Business Alliance and the Leicester Square Association,” explains project manager Michael Frisby. “Those investigations informed our demolition design and methodology and these were shared at an early stage with our client.”

Into this well-trodden arena came John F. Hunt, the demolition contractor charged with partially demolishing the former home of the Automobile Association during a 12-month contract whilst retaining its four-sided façade, minimising disruption to the numerous cinemas and hotels that line the local streets, and keeping those 37 million pedestrians safe.

Those designs were complex in the extreme. The four external elevations of the former eight storey (plus rooftop plant room) were to be retained from the fifth storey cornice downwards. The internal basement and slab were to be removed to facilitate piling in preparation for the construction of the replacement building which will comprise high-end retail at ground level and seven floors totalling 8,500 m2 of office space. That building, which is scheduled for completion in 2016, will feature a new core, new floorplates, a new upper storey of accommodation and a new roof.

The History Boys 48 Leicester Square is probably best known as Farnum House, the original home of the Automobile Association. But the address on the west side of Leicester Square stretches back considerably further than the roaring 20s. Indeed, portrait and historic painter Jeremiah Davison called the place home in 1750 and was later owned by James Christie, the tailor and not the auctioneer of the same name as is often claimed.

Top Guns Key to the successful completion of these complex works was an equally complex set of temporary works charged to John F. Hunt and their in-house design engineers. Immediately after the investigations, asbestos removal and soft strip were completed, a tower crane was erected through a central core to facilitate the delivery of mini excavators onto the back-propped upper floors to begin the top down phase of the demolition. “The erection of the crane was the pre-cursor to the commencement of the structural demolition. A cantilevered scaffold was to be erected to the fifth floor while the first parts of the temporary works were put in place,” Frisby recalls. We were effectively demolishing from the top down while the scaffold and temporary works were installed from the bottom up.

As a result, crane hook time had to be scheduled to ensure that we and our subcontractors could maintain their respective processes.” Those temporary works comprised some 250 tonnes of steel arranged as three levels of trusses supported on five towers. As works progressed, these works ensured the stability of a four-sided façade surrounding a hollow inner core that increasingly resembled a Roman amphitheatre. “Two and three-sided façade retentions, particularly in London, are nothing unusual. But a four-sided façade retention is something different altogether,” Frisby says. “And one of the biggest challenges is that there were no discernible exit for materials.”

No Way Out Steel and timber removed from the upper floors of the structure was craned down in skips while around 10,000 m3 of reinforced concrete was pushed down through a shaft to the ground floor for onward processing and removal. With the assistance of Westminster City Council, John F. Hunt secured a regular lane closure of nearby Whitcomb Street to facilitate the removal of “waste” materials.

Hardcore was transported to a recycling plant in Stratford, east London where it was crushed to a 6F2 grade. Steel was removed to a facility in Canning Town – also in East London – for recycling, while local company Westminster Waste handled waste timber. Despite the challenges of materials handling and removal, John F. Hunt easily exceeded its original recycling rate aim of 95 percent, ultimately recycling 99 percent of arisings from the site.

Someone to Watch over Me Not surprisingly, given the high profile location, John F. Hunt was also required to adhere to just about every kind of monitoring and scrutiny known to the demolition world. “There is a hotel very close to the site together with some residential properties. And, of course, we couldn’t afford to have complaints from the major cinemas about noise,” Frisby asserts. “The

site was monitored constantly for noise, dust and vibration. We limited our works to a strict 60 hours per week, often scheduling staggered shifts to avoid movie premieres and other local events. Despite these numerous challenges, we completed our works without a single complaint.” One of the key factors in achieving this “zero complaint” record was John F. Hunt’s careful interaction with pedestrians. The site hoardings contained information about the works throughout and, through stakeholder liaison meetings, local businesses and residents were kept informed of the progress and any specific points of the demolition. “The signs on the hoarding proved really popular,” Michael Frisby concludes. “They told locals enough to keep them informed but not enough to make them curious.”

History Repeatin Having recently completed its fifth tower block demolition in the same South London road, it would be no surprise if Sloane Demolition’s vans could navigate themselves to Putney. Mark Anthony reports.

Residents and office workers in Putney could be forgiven for doing a double-take at the hoarding outside the latest Sloane Demolition site in the area.

Having previously demolished four tower blocks – a mix of residential and office accommodation – over the past few years, the company popped up again at 111 Upper Richmond Road; a nine-storey block just a few doors up from the company’s last visit to the road.

With residential buildings to the rear and to either side and with businesses and main feeder road into London out front, a lack of disruption of any kind was a key consideration in the companyâ&#x20AC;&#x2122;s decision to opt for a top-down approach.

A Kubota KX-101 mini excavator on hire from Rhino Plant Hire and equipped with a hydraulic breaker carried out the lionâ&#x20AC;&#x2122;s share of the work while a Bobcat skid steer loader provided support, pushing debris down the former lift shaft before it was removed from site for onward recycling and resale. Sloane Demolition reports that the 16week demolition contract was completed ahead of schedule with zero reportable incidents and a recycling rate of approximately 95 percent. And while the Sloane Demolition hoarding has now been removed from Upper Richmond Road, no-one would be too surprised if it reappeared some time soon.

On Hire Ground There’s a new name in the high reach excavator business and it is not a manufacturer, modifier or contractor but a specialist hirer. Mark Anthony hails the new Messiah.

If you squint (and I mean REALLY squint), Tony O’Sullivan looks a lot like actor Jason Statham’s slightly skinnier brother, complete with cropped hair and designer stubble. But while Statham is busily taking his shirt off (again), attempting to nail down a credible American accent, and battling with the hardship of waking up beside lingerie model Rosie Huntington-Whitely each morning, O’Sullivan has his mind on higher and hire things.

Demolition Central There is an area around Dartford Bridge that is the unofficial demolition capital of the UK. Erith Group and John F. Hunt are just up the road, and bucket and breaker-maker Miller GroundBreaking has set up shop there too.

on site And all of this stems from a depth of knowledge of the Caterpillar equipment range that is unparalleled outside the confines of the construction equipment giant’s Peoria home.

Empty Yard, Profitable Yard A wander around the Messiah Corporation yard is like stepping into a Caterpillar Performance Handbook made real. Among the more than 200 machines there’s a couple of dozers – D6 models - in one corner; a massive Cat 992D wheel loader complete with mining-style tyre chains has been shot-blasted and is awaiting re-spraying in the workshop; and a line-up of Cat excavators of varying sizes and vintages line the perimeter wall like sentry guards. Fascinating though all this kit is, I am here with a specific interest – High reach excavators. Tony O’Sullivan leads to a disappointingly empty area of his yard where a single high reach boom – the name CDC Demolition now barely visible along its length – the only evidence of O’Sullivan’s demolition aspirations. But what is disappointing to the photo journalist is manna from heaven for a plant hirer for whom an empty yard is a profitable yard. And the reason there are no machines to photograph is that they are out on hire to the likes of Squibb Group.

In the midst of all of them is Messiah Corporation, a modestly-named used equipment specialist with a taste for Caterpillar equipment and an eye on the demolition prize.

Despite the wide open spaces that greet us, it is clear that O’Sullivan is taking his assault on the high reach hire business extremely seriously. Using his in-depth product knowledge and calling upon his global contacts in the used equipment arena, O’Sullivan has quickly assembled a multi-million pound fleet comprising 17, 21 and 28 metre reach models.

At the helm of this enterprise is Essex-boy-madegood Tony O’Sullivan; a man with a mobile phone seemingly welded to his ear; and an accent so thick it would make Del Boy sound fresh out of elocution school. But beneath that wheeler-dealer exterior is a determination to make a difference in the UK demolition business; a willingness to overcome the expense of high reach excavator ownership with an easier-to-swallow hire alternative.

Some have arrived in the Messiah fleet complete, others have been assembled from individual machines that have been acquired and cannibalised to match the specific demands of the UK demolition business.

Verachtert tool. Minimum hire duration is one month and hire rates vary from around £2,000 per week to around £4,000 per week. Any damage to a machine can be repaired by the company hiring it or charged by Messiah at cost plus 25 percent. O’Sullivan says he is aiming to have a fleet of 10 high reach and demolition spec machines on hire by the end of the year.

Regardless of their point of origin, each machine bears the Messiah stamp of quality. “We test each and every high reach boom we have before it goes out on hire,” O’Sullivan insists. “Each machine is thoroughly tested, repairs are carried out as necessary by a qualified engineer, a certified guarding package is fitted, and the machine is even badged in the name of the company that is hiring it.”

With a multi-million investment under his control, it is little wonder that Tony O’Sullivan is keen to protect his fleet. He insists that operators are fully certified to high reach standards and customer companies’ financial and insurance details are checked as well. Although he is still building the excavator fleet, Tony O’Sullivan is already looking ahead at the possibility of creating a complementary attachment hire fleet including tools from the premium brands such as Verachtert and Genesis. Until then, his intentions are clear. “We have no interest in doing demolition or cutting buildings up,” Tony O’Sullivan concludes. “We just want to offer the best and most extensive high reach and demolition equipment hire fleet in the business.”

Flexible Approach According to O’Sullivan, the concept behind his personal assault on the demolition market is simple. “A high reach machine will set you back half a million pounds or more and it might be sat in the yard for six months out of twelve or even more as they’re not suitable for every kind of demolition,” he explains. “Instead of having a lump of depreciating metal in the yard that they’re using two or three times per year, our customers can just call off machines as and when they need them, and off-hire them when they don’t.” And when customers DO need a machine, they have something of a Caterpillar treasure trove from which to choose. The 17 metre Cat 325, for example, was originally designed as a face shovel and as a result carries 6.5 tonnes of counterweight instead of the usual four tonnes; has an uprated hydraulic pump; hydraulic rams from a larger Cat 330; and the whole thing is carried on a wider than usual undercarriage for added stability with the former CDC Demolition boom that has been line bored, pinned, bushed, rewelded and fitted with new rams and seals. The Cat 345 machine – which is on hire in 28 metre UHD configuration – sports a unique tilting and elevating cab combination. The largest machine in the Messiah fleet is a Cat 365 that reaches nearly 15 metres with a seven tonne

You know how some things are just, you know, right? The iPhone, for example, is just right. The Coca Cola logo, the Audi R8, New York’s Chrysler Building. All just right. Well add to that list the new Liebherr R 974 demolition spec excavator that has recently trundled onto the Didcot A site to spearhead the demolition of this defunct coal and oil-fired power station.

Application-Matched Coleman and Company is rapidly establishing a reputation for its ability to match machine with specific application. The company worked with JCB to design and build a remote-controlled excavator for its contract at Birmingham New Street. We reported on its new “safety-first” JCB skid steers that were destined for the Didcot site. And now, the company has gone large and purchased a custom-built Liebherr R 974 that will spearhead the years of work required to level the power station.

That Liebherr are among the premium providers of demolition excavators has never been in any doubt. But there is something – some je ne sais quoi – about this machine that takes the really good into utterly exceptional territory. It might be the clean lines, the minimalist yet wellprotected styling, or the massive fiddler crab claw red attachment slung from the machine’s dipper. But, whatever it is, this machine is a bit special.

Power to Spare Beneath the armoured skin of this Coleman and Company-liveried behemoth beats a heart that is pure Liebherr. It is powered by a fuel efficient and emissions compliant Liebherr D 9508 8 cylinder diesel engine developing 400 kW (that’s 544 horses worth) of power.

Front-End Equipment In standard mode, the machine is equipped with a basic boom and multi-coupling system. A six metre plug in boom fitted with high pressure hydraulic lines can be switched over in a matter of minutes, while a 2.9 metre stick features an oversized bucket ram. The machine features an additional hydraulic control circuit to control the massive LaBounty MSD 7500R attachment supplied by ECY Haulmark. "As our schemes for complex demolition projects become increasingly innovative, it is entirely logical that the plant and equipment used, must follow suit,â&#x20AC;? concludes Coleman and Company managing director Mark Coleman. â&#x20AC;&#x153;This design led demand has been fully embraced by first JCB and now Liebherr."

The machine is carried on a VH-HD tracked undercarriage with 750 mm double-grouser track pads and carries 16 tonnes of counterweight, 10 tonnes of which is removable mechanically. For optimum on-site safety, the machine features rear and side mounted monitor cameras. A switchable travel alarm is mounted in the cabâ&#x20AC;&#x2122;s right joystick. The unit is operated from a demolition-specific cab with a full guarding package and 30 degree tilt. Extra comfort seat and air conditioning make the cab a genuinely pleasant place to be. But it is at the business end of the machine that the Liebherr R 974 really shines.

Demolition, But Not As We Know It

What lurks behind the traditional façade of Carey Group’s Wembley headquarters is a pristine and space-aged glimpse of the industry’s future. Mark Anthony penetrated the company’s inner sanctum.

I have driven past Carey Group’s innocuouslooking headquarters countless times on my way to first the old and, latterly, the new Wembley Stadium. As an England football fan by birth, and a West Ham fan by choice, it is a journey that I have long associated with hopes dashed and with disappointment. Yet, even in the hours of traffic jams on the way to yet another “close but no cigar” sporting moment, I have often wondered what lurks behind that familiar yellow and blue façade. For, having written about construction and demolition for long enough to see West Ham relegated and promoted at least four times (I have stopped counting), I had never been granted access to Carey Group’s HQ. To the best of my knowledge, I have never upset them, and they are far from aloof. But this is a company that has never really craved media attention because,

frankly, they just don’t need it. However, when my friend Ryan Lee joined the company, I seized the opportunity for a glimpse behind the curtain.

Minimalist Haven At first glance, the near-empty plant yard, nearempty workshop and head office building configuration of the Carey Group HQ is in keeping with demolition companies large and small, the world over. But the empty plant yard speaks to a company that is seemingly constantly busy; a company that takes care of its plant and vehicles meaning the workshop echoes to the sound of Capital Radio and not much else. And yet even this does not fully prepare me for the headquarters itself. A modernist reception area leads onto an open plan office, the likes of which I

Home from Home

have never seen in the world of demolition. Several hundred people – only some of them employed by the company’s demolition division – sit at clean and tidy workstations equipped with the very latest computer technology. The walls – where there are walls – are emblazoned with inspirational quotes including, appropriately: “Set some goals, then demolish them”. At the far end of this huge space rises an open plan boardroom where you fully expect to find James T. Kirk peering down from his captain’s chair. This area boasts every multimedia tool you could hope for and looks down upon a company nerve centre that hums, hive-like, with quiet activity.

Head offices are one thing; site offices are generally another. Not so in the case of the Carey Group’s TE Scudder contract that is redrawing the town centre landscape of Reading in Berkshire. For the duration of the 33-week demolition of the derelict Friars Walks Shopping Centre and the neighbouring 14-storey Western Tower, its accompanying bingo hall and a bus garage that runs beneath, the company has taken over part of a neighbouring office block. This too is equipped to an almost palatial standard complete with fine wood boardroom table and multimedia presentation capability for head office quality client meetings. And the walls replicate those inspirational quotes from the company HQ, partly as a constant reminder and partly to make this feel like a home away from home for its staff.

This is a demolition company headquarters as imagined by Steve Jobs and Sir Jony Ive; a perfect match of form and function; an air-conditioned, minimalist haven; a place where staff look forward to the start of the working day and from which they’re in no hurry to leave.

Such trappings and niceties do not extend onto the site - part of a £500 million redevelopment of the town centre around the railway station - although there is still the feeling that this is how demolition

This is certainly the case with Ryan Lee. After the guided tour of the main office, he leads me “below

On site should be. Even though I am expected, gaining access to Fort Knox would have been marginally easier; the site boasts enough dust suppression to turn the Sahara into a bog; and the lead excavator is a veritable Swiss army knife on tracks.

Complex Programme

The entire demolition process has been designed and engineered via a three-dimensional plan that was created in-house by one of Carey Group’s fiveperson-strong CGI team. “We use the CGI in a number of ways,” explains head of business development, Shaun Rowberry. “We use it initially to develop and engineer the safest and mosteffective demolition method. We use it at pretender stage to demonstrate the proposed demolition process to the client and to satisfy them that we have fully understood their requirements. Once on site, the CGI is used in daily and weekly planning meetings and in site inductions for new members of the team so everyone can see precisely what we are looking to achieve.” Although as a specialist contractor neither Carey Group nor TE Scudder is directly responsible for Building Information Modelling (BIM), both the existing 3D and the recently acquired 4D modelling and project planning systems employed by the group are fully BIM compliant.

The Armac high reach is responsible for removing a parade of shops to make way for a temporary entertainment park that sits in the midst of the 1.6 hectare site and which has events planned for this summer. Western Tower will be brought down using floor-byfloor top down methods. The original plan was to use this methodology down to level six although the company is now considering maintaining those methods down to level three or four to avoid unnecessary delays for the removal of the tower crane and the striking of the scaffolding.

The company will require all the project planning capability at its disposal on a contract that, while well within its demolition capabilities, is a very picture of complexity and finite scheduling.

Adding to the complexity of the process is the presence of a bingo hall and a bus garage that runs beneath, both of which appear to have been engineered to withstand a nuclear attack such is the quantity of asbestos lurking within and the thickness of some of the concrete beams. And then there’s the small matter of propping then dismantling the Garrard Street bridge that formerly linked the shopping centre and adjacent multistorey car park to the town centre’s main pedestrian area. For all that complexity, the site exudes an air of

controlled calm and of carefully choreographed processes. Everyone knows their role and although a lot of the site workforce is of Eastern European origin, only site manager Garth Thompson – his Scottish accent redolent of heather, haggis and deep-fried Mars bars – is hard to understand (sorry Garth). This, then, is demolition on another level. The UK demolition sector boasts a number of extremely impressive and admirable businesses. But if you’re looking for the sector equivalent of a

on site Armed with this information, we can understand why a zero tailswing, high reach demolition excavator is simply not possible. For such a thing to exist would be a freak; an unnatural aberration on a par with a bumble bee flying in contravention of all known aerodynamic principles. But the laws of physics reckoned without the “necessity is the mother of invention” mindset of a modern demolition contractor, and the “anything is possible” attitude of an experienced excavator modifier. Which is why a site in north-west London is currently playing host to a Hyundai 235LCR-9A zero tailswing excavator with a 16 metre reach front end that is happily waving some three tonnes of front end equipment in the air.

Steady As She Goes The machine in question started out as a standard Hyundai 235. And while at first glance the modified unit just appears to have an extended front end, there’s much more to the Kocurek-modified machine than meets the eye.

The machine now includes a dedicated demolition boom, a new intermediate boom and dipper that provide it with its 16 metres of reach. High visibility roof glass and a purpose-built guarding package protect the operator and ensure clear vision of the Prodem attachment. A key change is the addition of underslung counterweight which allows the machine to wield some three tonnes of tool and coupler without turning the machine into a nodding donkey and giving the operator seasickness. In truth, however, the base machine proved surprisingly stable, even with the extended boom. “This was the first Hyundai we have undertaken of this size and we expected it to be similar to the Hitachi ZX225USR machines that we have converted in the past,” says Kocurek Excavators’ general manager Brian Carroll. “Simon Barlow at Rye Demolition has been threatening to buy a Hitachi 225 for 18 months. But he opted for the Hyundai. And if our stability testing is anything to go by, he will be very happy he did.” To see Rye Demolition’s new machine in action, please visit: http://tinyurl.com/n9wb9bf

Worsley Seeks Success Worsley Plant will be using the PlantworX 2015 exhibition to launch a brand new concept screening bucket.

According to Worsley Plant, the Crossover bucket XO for short - is a totally new concept in the attachment sector. Put simply it is a bucket frame which can be connected to several work modules, enabling users to switch between modes in as little as 10 minutes rather than changing bucket.

There are 3 modules available: •SB Module •SC Module •SV Module

Crossover Blade Screen Module (SB) Ideal for screening top soil or using for padding pipelines and cables. The rotating blades process even the most moist top soil and are available in several spacings. Also great for mixing soil, sand and fertilizers to get the ideal mix, landscaping, screening peat and soil stabilization

If youâ&#x20AC;&#x2122;re going to PlantworX 2015, you can see the new REMU Crossover bucket in action. If you canâ&#x20AC;&#x2122;t make it to the show, you can check out the video here: http://tinyurl.com/p4pkvfm

Screener Crusher Module (SC) An excellent choice when you need to grind lumpy materials such as topsoil. The crushing blades push the materials through the blades to make it finer. Applications also include mixing and aerating compost, grinding packed materials to make them loose, and crushing roof tiles and wood.

Vibrating Screening Module (SV) Based on a vibrating movement in conjunction with a screening mesh (available in various sizes). It is ideal for separating sand from paving stones for reuse, screening the sand or other loose and dry materials, and shaking waste and dirt out of recyclable material. Two different sizes of the Crossover bucket will be launched initially. The XO2090 is recommended for excavators over 5 tons and the XO2150 for excavators over 8 tons.

On the Tools

A Positioner-ActuatorManipulator (PAM) machine on hire from UK dealer STM of Tring has been able to dramatically cut concrete removal time for Bam Nuttall on its ÂŁ85 million tunnel refurbishment contract at Heathrow Airport. 60

The 18-month contract involves major work on the main and cargo tunnels serving Terminals 1, 2 and 3 in order to comply with the latest European tunnel standards and also to extend the life of the tunnels for a further 60 years.

operation. Also, weighing only 525 kg without a tool in place, the machine can be easily transported in a typical high roof 3.5 tonne van. Commenting on the PAM unit, Bam Nuttall's main tunnel manager Jon Daley said: "The machine proved incredibly beneficial for us as it produced the same volume of work as six men using hand breakers and was hence able to cut almost 10 weeks off the original concrete repairs schedule which resulted in a significant cost savings."

As part of the project, some 206 square metres of concrete repairs were needed to be carried out and, initially, this was done using hand-held electric breakers. However, because of the high levels of hand/arm vibration involved, these tools could only be used by an operator for very short periods of time which resulted in slow progress. Consequently, Bam Nuttall sought out the Canadian built PAM (Positioner-ActuatorManipulator) unit which allowed work to continue throughout the 10.30 pm to 5.30 am possession time. This was made possible as the breaker is firmly secured to an air-over-hydraulic powered two-piece arm which almost completely isolates vibration from the PAM's hand controls, with typical vibration levels of just 2.5 to 2.7 m/s2.

Doosan Upgrade Gathers Pace The new Doosan 40-50 tonne DX420LC-5, DX490LC-5 and DX530LC-5 are the company’s largest Stage IV compliant crawler excavators, providing significantly improved performance compared to the previous ‘LC-3’ Stage IIIB models.

The new Stage IV 40-50 tonne excavators offer the strength and productivity needed for heavy duty work such as large-scale earthmoving, moving rock, pulling down buildings, secondary breaking, loading haulers and pipeline projects found on quarrying and mining, highway, aggregate, demolition, utility and general construction projects. Featuring a distinctive new machine styling scheme, the ‘LC-5’ range improves the already high standards set by the previous LC-3 range, adding to enhanced comfort and controllability with new features to boost fuel efficiency, uptime

and return on investment, with a focus on increased power, robustness and agility. The new 42 tonne DX420LC-5 is powered by the Scania DC13 diesel engine, providing 257 kW of power at 1,800 rpm. The DX490LC-5 and DX530LC-5 are both powered by the Scania DC13 diesel engine, providing 283 kW of power at 1,800 rpm. The engines meet Stage IV emission regulations without the need of a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies.

Renowned for their excellent fuel efficiency, reliability and long service life, Scania engines combine exceptional power output with high torque at low revolutions. The new Scania engines in the DX420LC-5 to DX530LC-5 operate at a much lower engine speed of 1,800 rpm, down from 2,000 rpm in the Stage IIIB models, leading to significant reductions in fuel consumption, which factory tests show to be an average of five percent across the three models. In addition, the move to the Scania DC13 diesel engine in the DX420LC-5 excavator has provided an increase in torque of 11 percent.

k i t ta l k To help meet Stage IV regulations, Doosan has added a mass airflow sensor and exhaust brake to the engines. The mass airflow sensor allows the electronic control unit to improve the management of airflow provided by the variable geometry turbocharger and to optimise fuel delivery to the combustion chamber based on air intake volume and rpm. Other exclusive features of the Scania engines are the dual fuel filter and water separator systems. In the first, a full-flow paper fuel filter is used to remove large particles with a centrifugal cleaner filtering out small particles, providing operating economy and lower environmental impact. The water separator utilises a 10 micron sized primary filter connected directly to the fuel tank, and a 3 micron sized pressure-type secondary filter. The systems are equipped with a heating function as standard for better cold crank performance. The excavators have a pre-heater with glow plug installed on the engine, which is a cold-start aid device for the winter season. The pre-heater is activated automatically when the start key is in the ON position in the ignition and the coolant temperature is -10 °C or lower. The system guarantees proper starting down to -20 °C. The engine coolant heater is used in connection with the machine's own heating system to pre-heat water-cooled engines. The engine coolant heater operates independently of the engine and is connected to the machine’s cooling, fuel and electrical systems. There is also a wake-up function to pre-heat the machine. The engine coolant heater helps the engine and equipment start and operate at temperatures below -20 °C.

As well as the fuel efficient Scania engines, new innovative and exclusive features have been introduced that together lead to huge reductions in fuel consumption amounting to an average of six to 13 percent compared to the Stage IIIB machines. Among these features is the new ‘Trip Meter Setting’ screen which allows operators to check fuel consumption daily (or over a desired period) directly from the control panel; the new Auto ShutOff provides an automatic shut down for the engine after a pre-set time when the machine has been idling for a specified time (3 to 60 minutes configurable by the operator); and to save even more fuel, there is a special Doosan-developed system, Smart Power Control (SPC), to optimise the balance between the pumps’ output and the diesel engine. The DX420LC-5, DX490LC-5 and DX530LC-5 have an optimised cooling system, which separates the radiator and the oil cooler. There is one fan drive pump attached to the engine and one fan motor for the oil cooler. The fan for the radiator is driven by the engine shaft directly. The turbo charger is now better protected, and a step has been added on top of the engine to allow extra access for maintenance. The storage box is slightly larger for better storage from ground access, and the fuel pump has been relocated to the storage box for more convenience. The batteries have also been relocated inside the left radiator compartments (previously in the tool box) for easier access to the battery disconnection switch. The excavators are equipped with a battery capacity of 2*100 AH (1,300 cca), which provides strong cranking performance in cold environments.

The DX420LC-5 to DX530LC-5 are factory-installed with the new CoreTMS state-of-the-art wireless fleet monitoring system, a feature not previously available as standard on Doosan excavators and now incorporated in all new LC-5 generation machines above 14 tonne. The new CoreTMS system is a tool designed specifically for the Doosan range, providing comprehensive information about machine performance in a dual mode (satellite, GSM).

New gauges, functions and menus have been added to the control panel, including a new AdBlue速 gauge. A new quick menu bar has been installed which allows key functions to be accessed quickly, without having to go through all the menus and validations. A side-view camera is available as an option and the control panel allows the views from both the rear and side view cameras to be combined on the same screen, simply by pressing a button on the control panel. For more safety when using the cameras, a menu bar now stays open so that the operator can keep an eye out for warning symbols and the levels of key gauges. In the DX490LC-5 and DX530LC-3, there is the additional safety feature when starting the engine of a new menu which allows the rear camera view to appear by default on the control panel.

Because the software in the CoreTMS system has been upgraded to communicate directly with the EPOS system on a Doosan excavator, it is the only tool of its type capable of providing this level of information, delivering insightful and cost-saving data about equipment to help customers work more effectively. Also available for retro-fitting in a kit form, the CoreTMS system is supplied with a free 3-year subscription in new LC-5 excavators and customers are provided with their own account so that they can manage the machines in their fleet using the system.

All current options including narrow tracks, short and long arms, shoes and hydraulic lines are available on the DX420LC-5, DX490LC-5 and DX530LC-5. The DX530LC-5 offers a 9.0 metre boom and a 6.0 metre arm with a reach of 16 metres or an 11 metre boom with an 8.0 metre arm with a reach of 19.5 metres.

Hammers to th Ten new Cat E-Series hammers designed for use with mini excavators, skid-steer loaders and backhoe loaders - are available in both "silenced" and side-plate versions. Four sizes H35, H45, H55 and H65 - are offered in two mounting configurations for installation on both Caterpillar and competitive carriers. Silenced hammers, identified with "s" in the model designation, use a fully enclosed housing to suppress noise, a valuable feature in sensitive work environments and in small-machine applications in which the hammer is in close proximity to the operator. Non-silenced, side plate models are available for all four sizes. Flat-top models allow versatility for installation on Caterpillar and equipment made by other manufacturers. Pin-on models are available for the H55E and H65E in applications that require a dedicated, hammer-equipped Cat machine. Several features assure convenient installation, comfortable operation and long hammer life. These

hammers are designed and engineered to match auxiliary flows and pressures of the Cat machine. Plus, hydraulic ports are positioned for convenient installation. As soon as the hammer is "plugged" in, it is ready to perform. Suspension system on the silenced models include buffers at the top and bottom to absorb reflective forces and isolate them from the machine. A suspension jack helps to dampen vibration and sound. The result is quiet, reliable operation and reduced operator fatigue.

e Power of 10

To protect the hammer from internal stress, an automatic shut-off can be activated. This instantly stops the piston when the hammer breaks through material which in turn protects the hammer from blank-firing. These new E-Series hammers include 47 percent fewer parts than did their D-Series predecessors. This allows for quicker and easier servicing. When it comes to daily maintenance, a single grease point is conveniently located and easily accessed. Tool changes are accomplished with common hand tools.

John F Hunt Rings Bell John F Hunt has purchased three B25E articulated dump trucks from Bell Equipment. According to the company, the small size and exceptional reliability of the Bell haulers make them ideal for land remediation on demolition sites. Having won a big contract, which would tie up at least several ADTs for two years, John F Hunt recognised there was an opportunity to extend the number of Bell machines in its fleet. The machines chosen are from the new generation E-series, which offers increased production payloads, lower daily operating costs, superior ride quality and uncompromised safety standards, as well as the lowest fuel cost per tonne on the market. The choice of the smallest size in the Bell ADT fleet – the 25-ton B25E – reflects the importance of having a high-quality, robust dump truck capable of working within the often confined spaces following a demolition.

The deal continues a working relationship between the firms that goes back nearly a decade, when John F Hunt first bought two D-series ADTs. Over the past nine years, these machines have performed exceptionally, as John Yeldham, Depot Manager at John F Hunt, explains: “The Bell dump trucks are reliable and hardworking and we’ve experienced very little downtime. On the rare occasions we’ve needed help, Bell has provided a great back-up service.”

“The Bell B25E is the ideal size for our purposes and we’re getting the excellent results we anticipated,” concludes John Yeldham.

Speedy Solution to Dust

In recent months there has been a concerted effort from the HSE to improve awareness of the potential hazards that workplace dust can pose and the necessary steps that construction firms need to take in order to ensure the safety of their workforce and to reduce its impact.

Speedy Hire is one of the UK’s leading providers of equipment and associated services to the construction industry, delivering a wide range of tools, machinery and support. Part of its offering is provided by Dustcontrol UK, a specialist supplier of dust extraction equipment. In light of the HSE’s attempts to improve understanding of the risks that dust can pose, Speedy Hire has undertaken a series of ‘Dust Innovation Days’ for some of its biggest contractors, including Balfour Beatty and Costain.

asthma and silicosis, an incurable lung disease, which causes up to 600 deaths a year in the UK. The success of Dustcontrol’s involvement in these days has seen the team receive invitations to do direct demonstrations for attendees who are interested in finding out more and educating their wider workforce.

These have been initiated by its major projects team following a rise in enquiries from the firm’s key construction clients looking for education on the necessary dust control procedures that are required to fit within HSE guidelines, with London based contractors displaying particular interest. The days allow for discussion surrounding dust control requirements, the reasons for them and the appropriate procedures to put in place in order to combat any negative effects. Dustcontrol UK was invited in by the major projects team to provide expert knowledge, offering specialist advice and instruction on how dust extraction equipment works.

“The Dust Innovation Days are fantastic opportunities to educate contractors on the serious issues that dust presents. Awareness in the industry is starting to improve, but with a concerted effort and a co-ordinated approach we hope to educate the whole of the construction sector,” concludes Dustcontrol UK’s Phil Haskins. “Speedy Hire’s approach is fantastic and we hope that others take up the baton with similar enthusiasm.”

Dustcontrol supplies a variety of products to Speedy Hire, the correct workings of which it is able to demonstrate to attendees during the course of the innovation days. These products include mobile dust extraction units such as the DC2800C and the DC3800C, which provide on-tool extraction, trapping dust at source and preventing it from escaping into the wider workplace. Other products, such as the DC Aircube, help to remove dust from the local atmosphere, filtering the air and extracting any dust particles from the flow. They help to provide cleaner and safer ambient air, making the workplace environment safer for construction workers and also reducing its impact on others working or living in close proximity. This is particularly pertinent when working in schools, hospitals and offices.
