Double-Edged Sword pool might comprise just four or five men.” Our insider also claims that the requirement for jobspecific training and accreditation has reduced the pool still further. “In the days of wrecking balls and traxcavators, everyone multi-tasked. If the crane and ball wasn’t working, the operator would be expected to get out of the cab and muck in, heaving a 40 pound hammer, burning, or manhandling debris,” he continues. “Now, everyone on a demolition site has a specific job and a set of qualifications and a card to go with it. They don’t get the same breadth of experience and that too impacts upon their ability to scale the career ladder.” At a time when the industry is struggling to attract new recruits and those that still recall working alongside traxcavators are heading for retirement, such restrictive pigeonholing of the current labour force is likely to have a severe and detrimental effect and could greatly worsen the industry skills shortage.

There can be little question that increased mechanisation of the industry has made the demolition process faster, safer and cheaper. Contracts that would have required upwards of 20 men just a few decades ago can now be tackled by five or less; and manual labour has been almost universally outlawed as demolition workers have moved back from the workface to operate machines and man well-appointed site offices that have all the comforts of home. And that’s a good thing, right? By and large, yes, it is a positive step in the right direction. But according to one industry insider, this degree of progress cuts both ways, resulting in a smaller pool of workers from whom to promote and advance through the demolition ranks. “Back in the days when there were 20 or more men on site, you had a large pool from which to train burners, top burners, mattock men and top men and, ultimately, site managers and contracts managers,” the unnamed insider claims. “Today, that resource

App Happy Travel Apps The life of the modern demolition man (or woman) is a nomadic existence: forever traveling and forever moving from site to site utilising a multitude of transport systems. Thankfully, as in all things these days… .there’s an app for that:

unlike more costly, dedicated sat-nav systems, this is regularly updated free of charge and does not require the purchase of maps should you have the audacity to travel overseas.

Tube Map – For those living or working in London or visiting from outside, the London Underground system remains one of the fastest ways to get around the nation’s capital. And the excellent Tube Map app is the fastest way to negotiate around the famous colour-coded network. Simply enter a start point and a destination and the app will work out the fastest route, proving you with change points and estimated time of arrival.

EasyJet – Speaking of overseas travel, the EasyJet app gets our nod as the airline app of choice. The app is true to the airline’s “no frills” ethos and is all the better for it, allowing users to find and book flights in under a minute for those last-minute escapes from the rigours of work.

The Trainline – If you travel by train, The Trainline is a must-have app. A comprehensive search function allows you to plan your route and, best of all, the app allows you to purchase tickets on-the-go for those last-minute meetings and weekend getaways.

TripIt – But our travel app of choice is TripIt. TripIt stores all your travel plans including train and airline ticket information, hotel reservations, meeting and appointment dates etc. It syncs with your iPhone’s internal calendar and – best of all – it is easy to populate. You simply email your airline, train and hotel confirmation details to a dedicated email address and TripIt does the rest, providing you with a step-by-step itinerary, reminders, flight status updates, and even places of interest. Highly recommended.

Maps – The native GPS app built into all iPhone models is about as good a satellite navigation system as you’re likely to find, switching seamlessly from car, train and foot travel. And,

Much More Than a Nuisance

With silica related deaths rising year-on-year, dust is a serious issue. James Miller, managing director at dust extraction specialists Dustcontrol UK, explores the matter further.

Silica dust is a problem that suffers from a lack of recognition. The majority of us have heard about the health hazards presented by continued exposure to asbestos.

hearing the word ‘asbestos’ know to be wary in its presence. The problems linked with silica dust on the other hand suffer from a lack of wider awareness. There are now more than six hundred and fifty silica related deaths per year, making it the second largest cause of occupational lung cancer after asbestos.

It’s widely covered in the media and the vast majority of people, even if they don’t work in construction or the associated industry, upon

Age-Old Issue Silicosis (as the lung disease is known) isn’t a new problem. Miners and stonecutters throughout the ages have suffered from its effects. However modern construction techniques have seen the impact of these effects increase significantly over recent years as the number of sufferers has risen sharply. Silica on its own isn’t a problem and is present in sand, granite, cement, stone and other commonly used building materials. The amount of silica contained within these materials varies. For example with sandstone, silica makes up between 70 and 90% of the content, however with marble or limestone, silica equates to only 2% of the total substance. The variation within concrete can see it range from constituting as little as 25% to as much as 70%, so it really does depend on the particular materials that have been used.

send RCS particles into the air, which can then make their way into the lungs. When it comes to demolition, the very nature of the procedures involved means that the risk of exposure to RCS is often higher than during other construction site activities.

Where silica can become a problem however, is during the course of common construction techniques. Activities such as cutting or grinding concrete, chasing out mortar and drilling in enclosed spaces, breaks down silica and causes it to form as respirable crystalline silica (RCS). It is RCS that provides the hazard, which, when inhaled, can cause incurable lung cancer following a prolonged period of exposure. RCS is extremely fine and isn’t visible in normal lighting, which means that, whilst you might think that the air is clear; this isn’t necessarily the case.

There is a responsibility for employers to put appropriate procedures in place in order to reduce the associated risks as much as possible. Poor controls in the workplace leave employees susceptible to potential health hazards, whilst also leaving employers susceptible to liability claims being made against them. Asbestos claimants have been awarded compensation running into millions of pounds. Victims of silicosis could look for similar damages. With this in mind then, it pays to be aware of the potential issues that prolonged exposure to silica can cause and to put appropriate safeguards in place.

Prevention Measures The prevalence of silica means that it’s not just miners and stonemasons who need to be cautious in today’s world. Anyone working in the construction industry is at risk, as simple tasks such as sweeping or the pouring of powders can

STUFF There are a number of steps that can be taken to minimalize the risks presented by working with silica dust; here are my top ten tips: Identify the problem By identifying any potential risk, you’re in the best position to help reduce the impact. List any activities that could present a hazard and consider the possibility of bringing in an industrial hygienist to undertake a full assessment. Use substitute materials As manufacturers of building materials become increasingly aware of the risks posed by prolonged exposure to silica dust, they’re looking for alternative solutions. Opting to use alternative materials that don’t contain silica completely eradicates the risk of silicosis. However, with demolition, you might not have much input on what materials have been used! Utilise dust extraction If dust is an unavoidable problem, then read the HSE document CIS36 and take appropriate steps. Mobile dust extractors built to Application Class M (medium) or H (high) help to take out the dust at source and eliminate the need for sweeping, nullifying the risk of it getting airborne. Wet it Water is the enemy of dust, so where possible use water to contain any dust in the air. Wet drilling and sawing is advised. Remove dust and debris with a wet vacuum or hose it down.

Workers should also be monitored and advised to take medical check-ups every 2-3 years. Be hygienic Crystalline silica has the capacity to stay on hands and clothing during the course of contact, so it’s as simple as washing hands before eating, drinking and smoking. Combine this with changing clothes at the end of the working day and taking a shower if possible. Training Education about the matter is key to helping eradicate the problem. The effects upon health as well as the importance of effective controls and the correct procedures to follow should all be ingrained in a workforce. Mask up Correctly fitted protective masks should be a minimum requirement in the presence of silica dust. FFP3 masks filter at least 99% of airborne particles. Effectively Communicate The presence of crystalline silica needs to be clearly labelled; if it’s in a greater concentration than 0.1% then a safety data sheet must accompany any products where this is the case. Signpost it If crystalline silica is present, make sure that the area is clearly marked and that warning signs indicate the potential hazard so that workers are aware.

Monitor the air for dust Using air quality monitors can tell you how much dust is in the atmosphere and help you to make a judgement on the appropriate steps to help control the amount of silica present.

HAVs Monitor Gets Personal Svantek has launched the world’s first personal hand-arm vibration exposure meter. The compact and rugged SV103 easily attaches to the operator’s arm whilst the lightweight MEMS accelerometer straps to the hand making it the only device to accurately measure the vibration dose being received.

“Many currently used assessment methods for hand-arm vibration are subject to a very high level of uncertainty. Typically vibration measurement accuracy can vary in the range of ± 20% to 40% which makes a big difference in relation to the risk of operators developing *white finger disease,” says Svantek sales and marketing director Paul Rubens. “As a result, our new SV103 is a real game changer. It significantly reduces measurement uncertainty as it is strapped to the operator’s arm and is small enough to take daily vibration exposure measurements without interfering with normal working activities. We are confident that the SV103 will set a new benchmark in hand-arm vibration exposure monitoring.”

In addition, Svantek’s new SV103 incorporates an additional contact force transducer that measures whether the tool is being gripped correctly. The lightweight, easy to use instrument meets ISO8041:2005 and is suitable for taking measurements in accordance with ISO5349 and European Directive 2002/44/EC.

Moving With

Industry bodies must embrace modern technology and modern attitudes if they are to survive and thrive in a relaxed and connected age. Mark Anthony reports. Take a minute to think about your daily working routine in this relaxed, informal, modern and connected world of ours. If you are anything like me, you are awoken from your nightly slumbers not by the ringing of an alarm clock but by the melodic tones of a smartphone.

Turning off that alarm, you might take a peek at your email inbox, the news headlines or your Facebook or Twitter feed before getting ready for work. If that work requires you to operate a machine, jeans and a t-shirt are de rigueur. If your job is more of a management or administrative role, you’re probably dressed like you’re heading to the golf course; an open-necked shirt teamed with chinos or something equally informal – If it’s good enough for David Cameron and Barack Obama, then it’s good enough for me. What follows will be a day filled with communication that is electronically-driven. It might be calls on a smartphone with more computing power than the Apollo spacecraft that first took man into orbit; or it might be via email

the Times using a tablet computer that looks like it has been beamed back in time from somewhere in the Star Trek universe.

Meetings between team members and even clients and stakeholders now regularly take place electronically via FaceTime, Skype or Google Hangouts linked to webcams to ensure that facial expression and nuance are not lost in the ether. Site progress photos are taken by and shared via smartphones.

LOOKING FOR WORK? 15

Opinion Face-to-face meetings are now conducted in casual coffee shops, huddled around computers and tablets. Business cards have been replaced by the electronic sharing of contact information; company brochures have been superseded with company websites and YouTube videos; and meeting notes are committed not to paper but to an electronic device for instant sharing and instant updating. Few of us wear a watch for anything other than fashion or a public display of wealth and affluence these days; the clock on our phones is more convenient and more accurate. And the real anoraks among us even pay for our Starbucks Frappuccino with a wave of an electronic device or a contactless credit card rather than dirt and outmoded cash.

While it is perfectly acceptable to haul around your smartphone, laptop or tablet computer, you will be expected to have it switched off (or, at the very least, set to silent) for the duration of the meeting. Mind you, there’s little point in having it switched on as the information provided is likely to come in dead tree, paper form that would require the addition of a scanner. Although high level business meetings with some of the UK’s largest construction companies and property developers are conducted in the casual surroundings of a Café Nero, industry body meetings seemingly must take place in hotels and venues with the correct oak panelling quotient. Then there’s the language.

Forced Formality

In the slightly-rough-around-the-edges demolition industry, we were quick to embrace informal business language. Clients and stakeholders are often referred to as “mate” (in London), “pal” (in Scotland), and “my duck” (in Nottingham). Swearing, once viewed as vocal proof of a narrow

Now compare that to a day that involves the meeting of an industry organisation, institute or federation. For one thing, those chinos and opennecked shirt aren’t going to cut it. Not only will you look out of place but the lack of a tie (the right tie) might even incur a financial penalty.

vocabulary, is now the lingua franca of the demolition and allied trades; curse words are used to add emphasis and humour and even as terms of endearment. At industry body meetings, meanwhile, it is still “Mr Chairman” this “subclause” that, and “constitution” the other; the language of a bygone age.

Victorian restaurants are where you take retiring employees for a final roast beef-flavoured send-off, all the while discussing your recent meal of snail porridge and mahi-mahi ceviche. The aspirational heroes of today are not landed gentry but football players and celebrity chefs for whom Estuary English is not a subject of derision but a badge of honour and realism; God Save the Queen is not a loyal toast, it is a punk rock anthem.

Aspiration & Alienation And there’s the rub. For the senior members of the demolition fraternity, formal language, suit and tie wearing and oak-panelled dining were aspirational; an unspoken proof that some of the most working-class working men could mix with the hierarchy, emulate the aristocracy; and dine freely in establishments that required noble breeding or a university degree in table etiquette and comportment.

If bodies like the NFDC and IDE are to have any degree of influence in the industry of the very near future, they must throw off the shackles of tradition and engage with the industry as it is and how it will be, not how it once hoped to be. Tradition and nostalgia have their place, and I enjoy brogues, heavy tweed and dining rooms that carry the lingering whiff of cigar smoke and affluence as much as the next man.

For the rising and future stars of the industry today, such traditions are not the stuff of aspiration; they are the stuff of alienation. Today, suits and ties are largely for weddings, funerals and boy bands wanting to be taken seriously as musicians;

But unless the powers that be set aside forced formality and earned pomposity, we might all be a part of the last generation for whom membership of an industry body is considered worthwhile, meaningful or relevant.

Keeping Cool Factory Fire Northbank Demolition recently completed the demolition of a former air conditioning equipment factory in Leeds. Demolition magazine reports. The fire at the Airedale International Air Conditioning factory at Rawdon, Leeds late last year was devastating. It destroyed large parts of the 23,000 m² facility and required firefighters to remain in attendance for several weeks. But in keeping with the region’s reputation for tough resilience, Airedale is planning to bounce back with a new factory within the footprint of its former premises. And following a competitive tender, Northbank Demolition Ltd was awarded the complex demolition contract to pave the way for the company’s phoenix-like return. “We weren’t the cheapest, but due to our health and safety record, previous contracts and recommendation we won the tender,” explains Northbank’s business development manager, Mark Mates. “The four month contract required the demolition of the fire damaged buildings, extensive asbestos removal and the breaking out of floor slabs to create material stockpiles in advance of the new build.”

With the demolition now complete, the air conditioning equipment manufacturer has submitted a planning application to Leeds City Council which proposes to rebuild the original Airedale factory facility on a like-for-like basis with roughly the same footprint and gross floor area. In addition to a new production shop floor, the proposed new single-storey building would include a replacement research and development test centre with the capability to test larger products, offices and training facilities. The new test centre will incorporate an extension of around 2,000 m² including a 2 MW chiller test chamber, 250 kW and 120 kW unit test chambers and a data server test room.

Objects of Desire

Editor Mark Anthony gets to grips with a new rugged computer tablet that could be the ideal solution for the websavvy demolition man at large.

Keep Taking the Tablet My trusty first generation iPad has incredibly strong ties to the demolition sector. My first 8 GB model was purchased – on a whim – at the Apple store in London’s Regent’s Street just moments after I left a nearby Erith Group demolition site. When that model was stolen from my hotel room in Las Vegas while I was reporting on ConExpo 2011, it was replaced at a nearby Best Buy by a 16 GB unit that has been my constant companion ever since. That iPad has reported live from industry events across the UK, Europe and beyond; it has displayed and edited demolition photos; it has played demolition video; and a good percentage of the articles in this magazine and on DemolitionNews.com were conceived, written and edited on a pre-retina-ready screen that now has a cataract-infected, milky quality to it. But there is one line that my iPad does not cross. Even though it is now three generations out of date and shows quite a few signs of wear and tear, my iPad rarely – if ever – goes onto a demolition site. I am happy to take my much newer iPhone 5. I am content to chance my much more expensive stills and video camera. But a demolition site just feels

too risky a place for something as fragile and aesthetically pleasing as a tablet computer. Until now.

Hard Knock Life The new Raptor R7 from Liverpool-based Rugged and Mobile Ltd is an Android system tablet computer that has been designed for a hard knock life. The unit comes wrapped in a rugged yet extremely lightweight protective case in an obligatory black and yellow livery that immediately feels right at home in a site environment. The Raptor R7 is significantly smaller than a standard Apple iPad, its small seven-inch display sitting somewhere between shrunken tablet and smart phone with delusions of grandeur. Indeed, the unit is equipped to make phone calls out-ofthe-box, although what your workmates will make of you conducting a phone call on a device the size of a paperback book we can only imagine. As a nod to its likely place of work, the unit comes with an adjustable strap that allows it to be held securely in either hand. Ours also arrived with a film screen protector to help protect the pin-sharp display from oily or dirty fingers. While this is easily removed, we would strongly recommend that one is installed as the glass is really the tablet’s only real Achilles’ heel. Headphone input, charging port and slots for a variety of additional cards and memory devices are all stowed under rubberised or plastic caps to ensure that they don’t get clogged with potentially destructive dirt and grime. While they unit may not be waterproof in the truest sense, those caps also provide a useful barrier to moisture, that destroyer of all things electronic.

As with all tablet computers, this unit is ready to use straight from the box without the need for software installations or updates. It is supplied with a wide range of useful apps including (not surprisingly) Gmail, Maps and a nifty FM Radio. From a business perspective, the Raptor R7 also comes ready to record sound, shoot photos and video, and to manage both calendars and contacts with everything synced back to a computer seamlessly via a supplied USB/Firewire connector. If those native apps don’t float your boat or allow you to accomplish specific work tasks, you can choose from more than 1.2 million free and paid for apps that are available from the Google Marketplace. When I trialled the Caterpillar B15 smart phone previously, I allowed my lack of experience with the Android operating system to cloud my judgement. On the Raptor R7 – with its larger screen and slicker interface – this was not an issue. In fact, rather than an obstacle, the Android operating system was more like a magical mystery tour.

Cut the Mustard So does the Raptor R7 tablet cut the mustard or is it destined to remain wrapped securely inside a protective sleeve, never to see the light of a demolition site? In my opinion, the Raptor R7 (and devices like it) could mark a turning point in the demolition field, bringing seamless (and paperless) information sharing to site level in a rugged form factor and

without breaking the bank. I already know of at least one major demolition company that is planning to switch its site paperwork for an electronic information trail and to equip it site managers with a suitable mobile device with which to view, update and share that information. The Raptor R7 from Rugged and Mobile Ltd could BE that device. Unlike previous attempts to bring mobile technology to the demolition world, this is neither ugly nor cumbersome. In fact, it actually looks as if it might have been designed by someone from the industry. You could carry the Raptor R7 onto any demolition site in the world without fear of your precious tablet becoming harmed or damaged and without the fear that your colleagues will mark you as some kind of poseur or geek. And, being entirely app-based, this device will suit even the most avowed technophobes.

Pros â&#x20AC;&#x201C; Compact size and rugged form factor makes this device totally demolition-ready, while the open-source Google Marketplace ensures that you have an almost endless supply of apps to suit your work and leisure needs. Cons â&#x20AC;&#x201C; All the while computer screens are manufactured from glass, they are vulnerable to impact, and the Raptor R7 is no different in that respect.

Blazing Squad AR Demolition has developed an expertise in making-safe and demolishing fire-damaged structures that others would find too hot to handle, as Mark Anthony reports. Unlike most of who see a fire and whose survival instinct compels us to run away, firefighters will head toward the flames. Unlike most of us who see a fire damaged building and think “unsafe and unstable”, the team at AR Demolition simply prepares for another day at the office. In the past few years, the company has dealt with several fire-damaged structures: some beyond salvage; and some requiring emergency attention to ensure that they can be saved. In that time, the company has developed a degree of expertise not normally associated with the average demolition contractor.

Managing Risks “Dealing with fire-damaged structures does add some unique challenges,” says AR Demolition’s Richard Dolman. “Even before we have set foot on site, there is an additional layer of communication and management involving the fire

service, the insurance company, and the owner of the building. Unlike the normal demolition of a building, the decision to carry out a complete or partial demolition of a fire-damaged structure is often made ‘on the fly’ to ensure the safety of the public and neighbouring buildings.

You do not have the luxury of months of planning time.” Despite this, Dolman says that he and his team take a very systematic approach to a burned-out building demolition.

ON site

Experts by Default “Ultimately, I need to be 100 percent certain that we have carried out all the correct risk assessments and that we all know precisely what we’re dealing with. Our philosophy is quite simple. If there’s a risk, we don’t go in and we just have to demolish from a safe distance until it is safe enough to go in,” he insists. “Obviously, fire-damaged buildings bring with them additional risks. By analysing the building thoroughly, working with the fire department, and carrying out any necessary structural checks, we can manage out most of those risks and be mindful of any others.”

Dolman explains that his company’s growing expertise in the demolition of fire-damaged buildings came not by design but by default. “We have always wanted to work with Leicester City Council but we had struggled to make any real inroads,” Dolman says. “But we took care of an unstable chimney for their building control department and they have seen our approach and our commitment to training. Slowly but surely we have convinced them that we have the expertise, equipment and experience to tackle increasingly complex works.”

ON SITE

A good example of this was the 6storey carpark and public arena of the Derby Assembly rooms building in the centre of the city.

According to Dolman, working with a fire-damaged structure requires a different mind-set from the demolition contractor. “For one thing, you have to get away from the ‘bring it all down’ mentality. You are dealing with people’s homes, buildings and money and it is vital that if anything can be salvaged, it should be,” he says. “There is also a temptation to view these jobs as an ‘open cheque book’ but we prefer to keep it tight and do it right. I don’t want AR Demolition to win just one job. I want ongoing work so we have to prove consistently that we are offering value for money.”

A fire in the plant room on the roof had spread to the multi-storey car park beneath, requiring a careful approach from the AR Demolition approach. “When I first looked at the job, my immediate reaction was to call for our high reach excavator,” Dolman recalls. “But that would have caused huge disruptions including localised road closures, significant damage to remaining structure and complex traffic management. Instead, we decided to take a more measured and calculated approach.”

That said, Dolman says that post-fire work does lend a degree of resourcing freedom. “If we are in a competitive tender situation, we are always looking at ways in which we might shave cost in order to win the contract,” he explains. “With a fire job, if you need an additional item of equipment, additional people or some other resource, you just do it because that is best for us, best for the client and best for the public.”

That calculated approach require AR Demolition’s structural engineering team to analyse the fire-damaged structure and to confirm that the building was stable enough to withstand a top-down approach.

Professional Capacity Dolman says that the freedom of fire jobs extends beyond the ability to order the right type of equipment. “Fire jobs are one of the few times in which everyone truly recognises and accepts our professional expertise,” he asserts. “Everyone from the fire brigade and the local council to the insurance company, building owner and CDM coordinator accepts that we are in charge and that we know what we’re doing. They just let us do what we do best and there is zero hassle.”

“Having analysed the building, they confirmed that the floor slabs would take a top down approach,” Dolman says. “Furthermore, with some localised propping in place, we were able to use an eight tonne Hitachi excavator on the roof, minimising the time the partial demolition would take.” The company utilised a 120 tonne mobile crane to place the excavator on the roof, employing a series of smaller skips to remove waste that was then

lowered to the ground by the same crane before decanting the waste into larger bins for onward processing and recycling. “Just because it’s a fire job doesn’t mean that we forget our environmental commitments,” Dolman says. Despite the additional demands, it is clear that Richard Dolman relishes the challenge of working on fire-damaged buildings. “I enjoy looking at a job from a different perspective, considering salvage as much as demolition, and being seen as the experts in our field,” he concludes. “I would happily do fire jobs every day of the week.”

Rankin Checks

It was holiday time for the team at E. Rankin Ltd when they tackled the demolition of a sea front hotel in Clacton-on-Sea. Mark Anthony checks it out. The destruction of hotel rooms is a past-time more normally associated with drug and booze-addled rock stars. But if the likes of Keith Moon and Axl Rose had been given access to the type of equipment used by E. Rankin Ltd on a recent hotel demolition project, just imagine the havoc they could have wreaked. The Hampshire-based company was charged with

the demolition of the 43-bedroom Comfort Hotel â&#x20AC;&#x201C; which was closed due to environmental concerns to make way for a larger, more modern 50bedroom Premier Inn at the popular seaside resort. The former hotel, and the land upon which it say, was purchased by Whitbread PLC almost a year ago and has been awaiting planning permission prior to the demolition and subsequent construction of the replacement hotel.

In Work tool sales & rental

During a six-week contract duration, the six-man E. Rankin team – including founder/owner Ed Rankin himself – used a Komatsu PC210LC excavator to tackle the heavy demolition of the three-storey building. Equipped with a rotator grab, the unit systematically dismantled the hotel, segregating materials as the works progressed to ensure that some 97 percent of all arisings were reused or recycled. Bricks and other demolition “waste” was crushed and retained on site to form the piling mat of the new Premier Inn hotel.

From Debt to Demolition A drastic career change has put Andrew Dickie on the demolition map; and has put his company – RoadRock UK – on the path to success. Mark Anthony reports. To the uninitiated, the name RoadRock might conjure images of an asphalt gang, an aggregates producer, or a jobbing band of musicians in the Traveling Wilburys mould. But the selection of this name for a demolition company is far more prosaic; far more telling. “For one thing, I didn’t want us to be pigeonholed as purely a demolition company, even though that’s what we are,” says managing director Andrew Dickie. “But also, the word demolition brings with it certain negative connotations that I wanted to avoid.” Given the fact that Dickie’s career started in the equally PR-friendly world of debt collection, such concerns are not without irony. But it is clear that Dickie is keen for his company – which is now in its tenth year – to plough its own furrow rather than blindly following what has gone before.

Going for Gold Dickie earned his stripes working as a subcontractor to the late Joe Romani who ran the Demolition Services company until his untimely death from prostate cancer in 2011. Dickie decided that the time had come for RoadRock to emerge from the shadows and become a force in its own right. He left Demolition Services’ north of England stronghold and headed back to his native south of England, setting up home in Southampton and setting up shop in Rainham in Essex. Although the Essex yard is rented and may ultimately be relocated, Dickie says that it is a perfect location, providing fast access to London and the M25 which is where most of RoadRock’s work takes place. To date, that work has been primarily subcontracted to larger and better-known demolition firms. But, having recently applied for NFDC membership, Dickie is keen to carve his company a slice of the pie for itself. And he is going about it in the right way. He insists on a high level of training for his staff and is a regular customer from the National Demolition Training Group which has bestowed numerous industry gold cards upon his 15-strong workforce.

And although he is retired, ex-Erith Group contracts manager Brian Grover plays a vital role in the company’s ongoing development.

Cradle to Grave Dickie admits that it is difficult to have a unique selling point (USP) in a market sector as vertical as demolition, although he admits that he is far more interested in machine-based demolition work and less interested in manual strip-out works.

But his approach is refreshing and speaks to a 39 year old’s eagerness to break the mould and look to the future. “You need to be upfront with clients and stakeholders,” Andrew Dickie concludes. “I would rather tell a client how it is in reality rather than keeping quiet, nodding politely and hitting them with a bill for extras afterwards.”

However, he says that his company prides itself on a “cradle to grave” approach. “In many larger companies, an estimator will work out a preliminary method statement and price the job accordingly. If that tender is successful, the job is handed over to site managers and equipment operators who often see a better, safer, more efficient demolition solution,” he says. “Our approach ensures that the same people see the job through from pre-tender and tender to completion. It ensures less confusion, less discrepancies between estimation and working method and, ultimately, is just better for the client.” The fact that he has applied for NFDC membership underlines Dickie’s willingness to stick with the traditions of the past.

Cradle to Gra

A former London hospital that helped extend the life of generations of the capitalâ&#x20AC;&#x2122;s sick children has finally come to the end of its own. And Downwell Demolition is charged with seeing the structure to its final resting place.

A former children's hospital in the East End of London is undergoing complete regeneration to provide a sizeable number of new homes with the initial demolition works currently being undertaken by Downwell Demolition. The Queen Elizabeth Hospital for Children in Tower Hamlets was originally formed from the merger of two separate childrenâ&#x20AC;&#x2122;s hospitals - one in Bethnal Green and another in Shadwell - during World War II.

ave The new hospital was established in a building on Goldsmiths Row which had originally been constructed as a Dispensary for Women and Children in 1870.

20th Century, extensions and alterations during the 1930s and the construction of the Hayward Building at the rear of the site in 1972.

Another Brick in the Wall For the following fifty years the hospital provided dedicated care for sick children with the original structure facility expanded with the addition of nurses’ accommodation at the beginning of the

Having been empty since its closure in 1997, the first task for Downwell was to empty and soft strip the nurses’ quarters, prior to the building’s demolition.

on site A major brick reclamation project on this building alongside the demolition work has been undertaken to minimise the environmental impact and attempt to recycle as much materials from the deconstruction as possible. “Being able to reclaim bricks for reuse is something we pride ourselves on. We will always attempt to employ sympathetic demolition techniques to maximise the salvageable materials from any project,” says Downwell Demolition MD Matt Phillips. “By doing so, it can give us a commercial advantage over some of our competitors and benefit our client by reducing overall project costs.” Following the soft strip, one of the company’s Komatsu PC340 high reach demolition rigs complete with rotating grapple was employed to delicately pick apart the nurses’ quarters, with the resultant bricks collected, cleaned and palletised by a team of demolition labourers. The ‘soft-touch’ demolition performed by Downwell was not just for the sake of improving reclamation rates. “This project has one of the strictest vibration tolerances we have ever encountered,” Phillips explains. “The local council has set a tolerance of one millimetre per second to ensure the disruption to local residents is kept to an absolute minimum, meaning we have to be very careful when carryingout our works on this site.” Once the nurses’ accommodation has been fully demolished to ground level, Downwell will be focussing its attention on the high rise Haywood building, previously used for laboratories, and the low rise A&E block, which includes the removal of asbestos by the company’s own asbestos division, Inner City Environmental.

Façade Retention The original Victorian building at the very front of the site will also be demolished, although the front facade on Hackney Road is to be retained using a temporary façade retention scheme. The building will initially be fully scaffolded with a Monarflex protection, before piles are sunk beneath the building to support a steel frame that will retain the structure’s front and side facades. The building will then be demolished in a controlled manner leaving just the original facade. This part of the project is extremely complex and requires a considerable amount of co-operation between Downwell and the temporary works provider, Becro. The remaining demolition work on site will take place behind a scaffold surround wrapped in Monarflex, with high reach machines allocated to bring the two structures down safely within the site’s boundaries, due to the site being flanked on one side by a variety of footpaths, cycle lanes and residential dwellings and the other, Hackney City Farm. Once all the former hospital buildings have been fully demolished, the concrete foundations will be broken-out, crushed and removed leaving the developer, Rydon Construction, a clear site capable of allowing the construction of 188 new residential dwellings, 70 of which will be affordable homes. “The conventional demolition involved on this project is relatively straightforward.

However, the site’s central London location coupled with the complexity of the facade retention scheme results in a considerable challenge,” Matt Phillips concludes. “Thankfully, my team, both on and off site, have the suitable level of experience and skill to ensure we deliver this project to our client both safely and to programme.”

Patient Care An ongoing strip-out contract within a Nottingham hospital is requiring care, consideration and considerable patience from the team at Cawarden Demolition. Demolition magazine reports.

Demolition works don’t come much more sensitive than working immediately adjacent to the children’s cancer wing of a major city centre hospital. But that is precisely the challenge facing the team at Cawarden Co Demolition as it tackles an ongoing strip-out of wards E39 and E40 at the Nottingham Children’s Hospital at the Queen’s Medical Centre as part of an upgrade of the hospital’s paediatric cancer care facilities.

Signed and Sealed That upgrade requires the removal of large sections of plasterboard ceilings, high-level ducting, vinyl flooring and concrete floor screed together with partition walls and some bathroom facilities. But with a live cancer ward next door, there is no room for a “wham bam” approach, as estimator/contracts manager Oliver Crooks explains. “There is no restriction on working times but the works are continuously monitored for noise and dust,” he says. “The entire working area is

sealed at either end and is semi-pressurised to ensure that any dust and debris stays within the confines of the site. Extraction fans are used to draw dust away from the live ward and out into the atmosphere.” Crooks, son of Cawarden managing director William Crooks, reports that this makes for a difficult working environment. “Because the work is sealed, there is no through-flow of air and the wards get very hot, even during cooler days,” he explains. “And then there is the challenge of extracting the arisings using nothing more than 660 litre wheeled medical bins.”

Elevator Delays To meet the strict health, safety and environmental rules imposed by client Interserve and QMC owner and operator – the National Health Service – all arisings are required to be bagged and placed into

medical bins before being sealed and removed to an outside service yard some four floors below. “As we have no space for more intensive materials segregation, we tend to work on one particular material at a time. Plasterboard ceilings for example. Once this has been bagged and placed into the bin, the bin is sealed and pushed out of the containment area,” Crooks says. “The bin is then vacuum-cleaned, wiped over with a damp cloth and pushed across sticky pads that remove any remaining debris from the tyres. While the site area is resealed, the bin then goes to the elevator.” So far, so simple. But the challenge doesn’t end there. The freight lift used to transport demolition waste to the ground floor is also used by hospital cleaning and maintenance staff and, on occasions, by patients. “Regardless of how busy we are, it is vital that the patients and hospital staff take precedence. If we’re taking a full bin down or an empty bin up and a patient needs the elevator, we will step out,” he insists. “As a result, it is not unusual for it to take 50 minutes for a bin to go down and come back up again.” This attention to detail and patient care is clearly appreciated by the client and the hospital administrators. “We have weekly site meetings to run through the planned activities and to address

any challenges that might arise,” Oliver Crooks concludes. “Both Interserve and the NHS representatives have been impressed by our approach on this challenging contract.”

Embassy Goes All Volvo North London-based Embassy Demolition Ltd has added four new Volvo ED220D excavators along with an EC480D three piece hi-reach demolition rig making its fleet of crawler machines virtually 100 percent Volvo. Established back in 1971, Embassy Demolition Ltd has taken delivery of four EC220D excavators and a bespoke three piece demolition rig mounted on a Volvo EC480D giving a maximum pin height of 26 metres. The machine can, if needed, be converted quickly back to standard backacter thanks to its modular boom joint.

“It’s the build quality and reliability we like about the Volvo machines,” says Embassy MD Jim O’Doherty. “They are robust and well specified for this sort of application.” Volvo’s level of after-market support is just as important to his operation with all of his Volvo equipment being covered by Volvo’s Blue Customer support agreements. Under this arrangement all his Volvo machines are serviced and maintained by qualified Volvo service engineers including regular inspections, oil sampling and analysis and comprehensive, proactive reports to maximise machine productivity with the aim of enhancing residual values. The four new Volvo EC220D machines have been equipped with FOGs guarding as well as additional 3rd hydraulic service lines to handle a variety of demolition attachments. (Hammer/shear and quick fit hydraulics are provided as standard). “Equipping the machines this way means we can have full flexibility for the contracts we are undertaking which can be anything from demolition to muck shifting, material or waste rehandling,” O’Doherty continues. The EC220D benefits from the use of Volvo’s Stage IIIB D6 engine, delivering 129kW of power and 849 Nm of torque, coupled to an improved hydraulic system with larger pumps which in turn significantly improves hourly fuel consumption with shorter cycle times. Operators can select the best work mode for the task at hand, ensuring optimum performance and fuel efficiency. Modes include: Iidle, F-fine, G-general, H-heavy or P-power, with the machine automatically setting the appropriate engine speed for the work mode and ECO mode is a new feature that works in G to H (or P) mode.

Pump flow is controlled for combined digging and swinging operations to reduce the flow loss through the overload relief valves, while maintaining digging power and maximum swing torque. Eco mode provides better fuel efficiency without loss of performance in most operating conditions. The EC480D supplied to Embassy Demolition with a bespoke three piece demolition rig designed and manufactured by Kocurek Excavators replaces an older EC460B model. With a maximum pin height of 26 metres and forward reach of 14 metres the EC480D is capable of handling a tool weight of 2,500 kg. The equipment features a hydraulic modular joint which enables the machine to be fitted with either ultra hi reach demolition equipment, a straight boom arrangement or as a standard backacter for digging duties. Further standard features to the Ultra High reach specification include a hydraulically tilting operator’s compartment; heavy duty belly plates; the Volvo SIPS (side impact protection system); five tonne additional counterweight, double thickness to side panels.

Wacker Neuson Duals Emissions Wouldn’t it be great if a machine could work dieselpowered most of the time but then have the option to switch to allow it to work safely and efficiently in zero-emission zones? Well, now it can. 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, for example, the excavator 803 is required for demolition / renovation work or interior restorations, the operator drives it in conventional mode to the site of operation. Two openings are embedded in the excavator’s dozer blade in which the HPU8 can be suspended for transport. In this way, the operator brings along the generator via this transport support. The dimensions of the excavator 803 and the unit HPU8 are matched to each other so that the end user can easily drive through narrow door openings with the set. Once arrived on site, the operator simply connects the external unit to the excavator’s undercarriage and can then continue to work completely free of emissions. The excavator is supplied with hydraulic power via the undercarriage. In this way, the tail swing radius

and possibility of a 360-degree rotation also remain unrestricted in electrical operation – which means complete freedom of movement for the operator. The operating weight, stability and dimensions of the excavator do not change with the option and the output also remains constant in operation with the generator. For the operator, the sequence of operations thus remain completely unchanged after the connection of the generator. The HPU8 unit designed specifically for excavator operation is characterized by its compact and sturdy design and the cooling capacity specially tailored for the compact excavator 803. The electro-hydraulic unit saves space, is easy to transport and is designed for work under full load

at up to 45 degrees Celsius ambient temperature as well as at low temperatures. The excavator 803 dual power and the generator HPU8 are also of interest for rental yard operators: A high machine utilization is ensured due to the versatile application possibilities – indoors and outdoors. The generator is connected to the excavator’s undercarriage via Plug & Play and is also no problem for less experienced operators. With a weight of 190 kg and compact dimensions, the unit can be stored and transported easily. The HPU8 is also very maintenance friendly: The simple design and easy-to-remove casing parts provide for good maintenance access.

Keeping the Faith The new EC140D is powered by a Volvo four cylinder D4H Stage IIIB engine developing 114hp which contributes to an excellent performance being well matched to the machine’s hydraulics.

John F Hunt Hire Services based in Grays Essex has taken delivery of four Volvo EC140D excavators for its civils hire fleet and demolition division.

The machine’s ‘Integrated work mode control’ provides high efficiency, rapid dig cycles and low fuel consumption. This advanced mode control system ensures the maximum possible hydraulic horsepower available is delivered at a constant engine speed under varying load conditions.

The four new Volvo EC140D’s were selected following a competitive tender process but in particular thanks to the reliability and performance of their existing EC140B machines purchased back in 2006. “Basically we have trust in the Volvo brand in terms of performance and reliability,” comments Managing Director Keith Scott. “Our EC140B’s have performed well in a mixed fleet of equipment, so the reliability as well as the after sales service we enjoy from Volvo has been deciding factors in our purchasing decision.” The new additions will be deployed in John F Hunt’s civils hire fleet or when the need arises, on demolition projects. The machines will also be hired out to end users.

In addition, boom and arm geometry provide highly competitive digging forces and lifting capacities, which makes for faster work cycles. Hose rupture valves are fitted as standard to the boom and dipper cylinders as are quick fit hydraulics and a hammer/shear service. The Volvo Care Cab offers a large roomy interior with plenty of leg room and foot space. The excellent all round visibility is enhanced by pressurized and filtered cab air supplied by a 14 vent, climate control system. An adjustable easy to read LCD colour monitor provides real time information of the machine

functions, important diagnostic information and a wide variety of work tool settings. The monitor also doubles as a monitor for the rear view camera. An optional heavy duty guard has been added to

the front windscreen and top of the cabin to prevent damage from brash, branches and other site debris.

Taking Fuel Advantage A rapidly expanding Scottish plant hire firm has just taken delivery of three 20-tonne JCB JS220 tracked excavators to capitalise on increased demand from the demolition sector. Based in Darvel in Ayrshire, Tom Grant Plant purchased the machines after identifying a gap in the market for a mid-sized excavator to perform clear up duties after heavier equipment has left demolition sites. According to the company, the JS220 has the power to handle heavy materials and attachments but offers greater manouevrability and cost efficiency than the traditional large demolition excavator. The new machines join two earlier JCB JS220s which were purchased in August 2013 and have been in high demand for the site clearance role ever since. The JS220 is the first JCB excavator above 20 tonnes operating weight to adopt the company’s highly efficient Ecomax diesel engine. The 4.8-litre engine delivers 129kW (172hp) and is equipped with 2,000 bar common rail fuel injection, a variable geometry turbocharger and full electronic engine control, resulting in a 10 percent cut in fuel consumption and improved engine responsiveness. As with all JCB Ecomax engines, the clean burn technology results in there being no requirement for a costly, and bulky diesel particulate filter (DPF).

“With its agility and excellent fuel efficiency thanks to the Ecomax engine, the JS220 is significantly cheaper to run than a large demolition excavator yet able to perform a wide range of handling, cutting and sorting tasks required as part of the demolition process,” says company owner Tom Grant. “We have spotted the opportunity to deliver this service – providing a smaller and productive machine than many out and out demolition contractors have in their fleet. In addition to the machines’ performance the service from Scot JCB is also excellent. Its response times on support or parts is rapid and the competition just can’t compete with that.” The three new machines have been specified with specialist auxiliary pipework, a rotation circuit and directional controls to give enhanced attachment utilisation. They have been put to work on a series of demolition projects across central Scotland picking up steel, wood and building materials and feeding crushers on site, using a range of attachments including buckets and a selector grab.
