CB Livelink proves its worth in battle against theft

The JCB 4CX backhoe loader recovered thanks to JCB LiveLink after being stolen by thieves

n SURVEYS

TRAINING & ASSESSMENT

constructionnational spring 2011

Thieves have been thwarted in their attempt to steal a top-ofthe-range JCB backhoe loader– thanks to the machine being fitted with the JCB LiveLink satellite tracking device as standard.

The JCB 4CX backhoe loader was stolen from JCB dealer Greenshields JCB’s depot in Hemel Hempstead. But it was recovered just hours later and all thanks to its JCB LiveLink telematic system, which gives real-time location information.

When Greenshields JCB staff discovered the theft, they logged into JCB LiveLink, which revealed the machine had been driven and parked up four miles away in Abbots Langley. They promptly recovered the machine.

During 2011 JCB’s 3CX and 4CX backhoe loaders, side-engined telescopic handlers and tracked and wheeled excavators sold in the UK are being fitted with JCB LiveLink and an immobiliser as standard – and the stolen 4CX was one of the first machines to benefit from JCB’s strong stance on plant theft.

Yvette Henshall-Bell, JCB’s UK and Ireland Sales Director said: “The recovery of this stolen machine in a matter of hours of the theft proves beyond doubt the benefit for customers of fitting machines with LiveLink as standard.”

JCB Insurance Director and General Manager Michael Gregory added: “Claiming for the theft of a valuable machine like a JCB 4CX would have had a profound effect on any business insurance renewal premium, so the financial advantages of fitting LiveLink speak for themselves.”

JCB LiveLink provides a telematic link to JCB’s machines which gives customers real-time location information, with curfew and geofence alerts – a real defence in the fight against thieves. In addition it can monitor the health of the machine as well as machine hours and performance.

JCB has taken a very strong stance on machine theft in the UK and Ireland, where every week more than £1 million worth of construction and agricultural machines are stolen – with just eight per cent ever recovered.

During 2011 and under the name ‘JCB Guardian’, JCB’s 3CX and 4CX backhoe loaders, side engine telescopic handlers and tracked and wheeled excavators will be fitted with both an immobiliser and the JCB LiveLink system which allows machines to be tracked and located by satellite if stolen. This is the first time that any JCB product has been protected as standard with both immobilisers and Livelink – a move that will help save some UK customers almost £1500 over three years in insurance premiums with JCB Insurance.

Extending protection to other products, JCB LiveLink will be installed as standard on JCB’s wheeled loading shovels and range of Telemaster articulated shovels. In addition, immobilisers will be fitted as standard on JCB’s range of compact telehandlers and mini excavators. q

Skills and Training

still top priority for construction sector Forecasts for the industry remain grim for the next year, but there is growth on the horizon, and that means skills and training investment is still a top priority for construction.

n

The latest findings from the Construction Skills Network, for the period running 2011-15, detail the predicted future skills and training requirements of the UK construction industry.

CITB-ConstructionSkills, which releases the data annually, is hopeful that the Government will now take action to support skills development and help create stability for the sector through core investment.

According to the report, employment levels are likely to drop by up to 76,000 jobs this year before there is a return to growth, but ConstructionSkills deputy chairman Judy Lowe says this figure needs to be looked at in context. “The industry went through a far worse situation in 1990 to 1993, when around 12 per cent of jobs were cut,” she says. “The good news is that we’re expecting to see either

constructionnational spring 2011

constructionnational spring 2011

a small upturn or a flatlining in the sector in 2012, which will be the first time since 2008 where there hasn’t been a decline.”

Importantly, the forecast shows exactly where areas of growth are likely to be. “Last year, repair and maintenance counted for around a third of all construction work. In the next five years, new build

work will only grow by around 0.5 per cent but repair will grow by 1.9 per cent. So, with 26m homes in need of energy performance improvement, there’s a lot of logic in focusing on training in skills appropriate for that sector,” says Ms Lowe.

Infrastructure as a specific industry sector is also tipped for growth.

Apprentices increase workplace productivity n

Wiltshire College offers a wide range of full and part time qualifications for the construction industry. With years of experience in construction related trades and with excellent facilities throughout Wiltshire, you can be sure that you will leave with exactly what you need.

They also offer apprenticeships in brickwork, carpentry & joinery, electro technical services installation, glass and glazing, painting and decorating and plumbing, bringing significant benefits to employers: Customise your apprentices’ training: ensuring that your apprentice is well equipped to meet your specific business needs.

A controlled and cost effective way of recruiting and motivating staff: offering training with a recognised qualification, with up to 100% funding.

Setting standards: an apprentice learns directly from you and will therefore quickly adopt your business practices and standards.

Address skills shortages for specific jobs: train the apprentice to fill the positions you need now and for the future.

80% of those employers who employ apprentices agree they make their workplace more productive. If you are an employer and would like to know how apprenticeships can benefit your business, or are interested in any of the construction courses on offer you can contact Wiltshire College on 0845 345 2235 and they will be happy to arrange a visit from a member of their team. q

constructionnational spring 2011

constructionnational spring 2011

“Infrastructure looks like it’s growing strongly. We also have 87 training groups devoted to specialist skills which can help firms enter specialist markets,” she says.

Further research by ConstructionSkills shows that 26 per cent of companies cut their training budget last year, with 18 per cent expecting to make further cuts this year. Ms Lowe warns that firms will need to invest in training if they want to pick up work during the recovery. “In tough economic times, training is seen as something that can be cut without having an immediate impact,” she says. “If you’re a business intending to grow and take on the low-carbon challenge, you need to start training now.”

In short, the report predicts that the next couple of years are going to remain tough for businesses, but a return to steady growth is on the horizon. So how should businesses react? The CSN data has helped CITB-ConstructionSkills to prepare a Five-Point Skills Plan for Government and industry which covers the key areas seen as vital to protecting jobs and supporting growth in the sector.

Firstly, it is essential to prepare for growth through increased productivity: Long term growth for the sector during a period when public spending is tight will require the industry to improve productivity so that it can stay profitable at a time when inflation is rising and margins are being squeezed. This will require a focus on maintaining existing skills and developing new ones, as well as innovation in working practices, to prepare the sector for growth.

Second, SMEs within the construction and built environment sector must be prepared to take on the energy efficiency challenge.

In a sector that accounts for 47% of all UK carbon emissions, the move to cut CO2 presents a logistical challenge but also a

sound opportunity for growth. This requires clear guidance from Government and an investment by employers to ensure the right skills and knowledge are in place to compete in this growing market.

Likewise, Government must engage with employers to meet the demand for skills, today and in the future: Working with the industry at a national and local level to guarantee the industry recruits the

CASE STUDY

Devon -based Coyde Construction is one company that is fairing well despite the current recession and has found real benefits in being a member of a regional Construction Training Group.

The company has continued to invest in its apprenticeship and staff training programme, as they realise the importance of ensuring that staff have first class skills and qualifications, not only to provide the business with competitive advantage now but to ensure that they are fully prepared for when the industry comes out of the recession.

Jenny Coyde, Director of Coyde Construction, explains: “It has been central to our business plan in these challenging times to have continued investment in our training programmes, as it is our staff who are at the heart of our business and it is essential that they have the necessary skills to make our business successful.

“This year we have a total of eight apprentices on our books, including three carpentry apprentices at NVQ Level 2, with two of these progressing to Level 3 in the autumn.

We have signed up to a further two apprentices this year, one in carpentry and one bricklayer.

“Through the Devon Construction Training Group and the funding it receives from CITB-ConstructionSkills, we have also been able to offer staff additional training and have a site manager about to achieve NVQ Level 4. We have found real benefit in being members of the group and the training advice it provides, as well as sharing best practice training routes with other employers in the region.

We are in good shape given the current climate and feel that our investment in training has really helped put us in this position.”

Coyde Construction recently received the Local Authority Building Council’s award for Best Social Housing Scheme, following on the success of winning the Best Community Project at last year’s awards. q

43,000 new workers a year it needs until 2015. Understanding the diverse skill requirements across the UK so that the construction and built environment sector can drive innovation and growth in communities across the country.

Industry must also tackle the recruitment challenge: Ensuring a pipeline of talented new entrants coming into the industry by championing apprenticeships as the best vocational route available, keeping this option front of mind for employers, students and the public sector. Looking for innovative, employer-led approaches to stimulate more graduate new entrants.

Finally, industry must develop education and training provision for all: Funding and training provision for new entrants must remain but not be to the detriment of developing the industry’s biggest asset, the existing workforce. To maintain the competitiveness of the construction sector we need to invest in ‘up-skilling’ and protect funding and training provision for adult skills.

CITB-ConstructionSkills already has a new business plan closely aligned with these proposals, and their broad spectrum of work, from recruitment and skills retention, to grant delivery and business support and training, will go some way to help. However, it is for industry and government to use the CSN findings to help make strategic decisions and pinpoint opportunities for growth over the next five years.

Equipping the UK with a well trained, productive construction workforce has always been central to the sector’s growth and success. But it is now essential if businesses are to succeed and grow, and it’s important to replace the skills lost to the industry during this recession. For that to happen we need to have a very clear understanding of the UK skills picture, including future needs, so that we can effectively plan and invest.

Skills and training should remain at the heart of any strategy to see the sector return to growth, and businesses need to make the investment now. Training can help enhance existing skills and provide talented workers with new ones – keeping them up to date with key legislation changes while positioning firms in the best light to pitch for new contract opportunities in a constantly changing and fiercely competitive market. q • To find out more about what skills and training can do for your business, visit www.cskills.org.

Stay safe and reap rewards NCC support to help businesses get benefits from staying safe

n

“Working safely can save companies thousands and deliver significant business benefits”, says Andy Walder, Director of the National Construction College (NCC).

“It’s not just about compliance with legislation – incorporating health and safety into a business could save employers unnecessary costs, and increase their productivity, helping them to get ready for forecasted economic growth.”

Despite continued improvement in the number of work-related accidents and fatality rates in recent years, the Labour Force Survey outlined that the construction industry lost 3.3 million working days due to injury and work related ill health in 2009/10, which cost the industry millions in sick pay, overtime and wages for temporary workers.

Workplace accidents affect product and service quality, customer satisfaction, repeat business and impact on the bottom line, which can have a damaging effect on businesses struggling to survive the recession.

Health and safety training is extremely important for the industry, as it helps to provide a safer working environment for employees while boosting morale and increasing staff retention and profits.

Similarly, a good health and safety record will provide businesses with that all important competitive edge, allowing them to succeed and grow.

Overall, the construction and built environment is waking up to

the value of Health and Safety. The NCC – the direct training division of CITBConstructionSkills – is running more courses than ever to meet this need.

One of the most popular offerings is the NCC’s Site Safety Plus package. It has an integrated programme of safety training for operatives up to those at management level, and provides businesses with the chance to select a health and safety programme that works best for their size, budget and individual worker’s needs. This includes courses such as Health and Safety Awareness, the Site Management Safety Training Scheme (SMSTS) and the Site Supervisors’ Safety Training Scheme (SSSTS).

Course provision is coupled with CITB-

constructionnational spring 2011 13

ConstructionSkills’ GE 700 Construction Site Safety Manual. As the leading industry publication for guidance on current construction health and safety legislation, the manual ensures businesses protect themselves, their people and their profits by bringing together everything that there is to know about construction health and safety training.

“Health and safety is paramount to the success of the industry and continued commitment to training and keeping abreast of health and safety legislation can help businesses remain safe and successful,” Mr Walder adds.

“At the NCC, we work with the construction sector to ensure its training needs are met, placing businesses in the very best position to pitch for new contract opportunities in a constantly changing and fiercely competitive market.”

Rope access a primary work solution for the construction sector

by RODERICK DYMOTT, Chief Executive Officer, IRATA International Simply... a solution

n

Considering the extensive use of sophisticated industrial plant and equipment that is deployed across the sector, and the long established procedures and processes that have accompanied the growth and development of construction work, it is somewhat refreshing that a simple and yet proven means of high and difficult access is available, remarkably safe, globally successful and able to offer very special benefits in addition to efficiency and effectiveness.

The use of ropes in construction is as old as time itself. You can imagine that workers building Noah’s Ark or the Hanging Gardens of Babylon deployed ropes as part of their construction progress, though perhaps not with the safe working culture that governs their 21st century use. Whilst a few remain sceptical about the role rope access can play in the industry, the majority, the more enlightened have recognised the dramatic increase in the use of this access method to solve many new or longstanding problems.

The rope access specialists trained and employed by the member companies of IRATA International worked in excess of ten million hours on rope in 2010, double the number of just three years before.

The role of rope access in construction Whilst it is normally the role of industrial rope access to provide short term and, often, small scale support to the sector it should also be noted that this does not stop its benefits being used on major iconic structures...Big Ben, the London Eye, our major bridges, historic houses, modern high-rise buildings and constructions, large and small, that present difficulties for many of the traditional construction methods.

The complexity of much construction work, particularly that including design features and materials that present difficulties for construction equipment and work procedures, is often simplified by the deployment of men working from modern ropes and a system that can see them set up for work in a fraction of the time

that others methods need, and then remove themselves from the site with equal speed.

The increasing design flair being shown in building design is not always good news for those who have to construct the more weird and wonderful shapes and then inspect, repair or clean them, though this is part of the reason for the increasing use of rope access. The curves, slopes and slants, and also the range of materials used, create long term problems for those who are more used to square, plain buildings and, as a result, there is increasingly a call to an IRATA company to help place and fit a particular feature and, later on, maintain its appearance and/or inspect its condition.

And there is no cause for safety concerns For those who have not yet bought in to the remarkable flexibility, adaptability and simplicity of industrial rope access there can be some concerns about safety because of the ‘Well, I wouldn’t do it’ syndrome. The facts are that IRATA rope access teams record the safest work statistics of any in the work-at-height sector. IRATA is a trade association, indeed it is the sole global organisation of the type in its sector, with member companies and training venues in every continent but that, in itself, does not guarantee safe working.

The key to all safe working is the level and standard of training given – do not allow anyone to convince you otherwise. All IRATA rope access training is undertaken by IRATA companies in venues that are regularly audited and required to be equipped and manned to set standards. The trainers are rope access experts with broad experience, including many thousands of hours on ropes, and the training they give is to a set syllabus so it can be certain that all the required knowledge is passed on.

Even though the IRATA work record demonstrates our responsibility and safety culture, training courses will include training for rescue and errors are corrected the moment they are seen. And these IRATA men, and women, do not train once and expect that to last a career but are required to re-train regularly to

constructionnational spring 2011 17

18 constructionnational spring 2011

maintain their level of expertise and do so again when they look to move to a higher grade. If this standard of training was applied across the construction sector we would surely reduce the deaths and injuries suffered.

But even good training does not guarantee safety Throughout the construction industry the most damaging feature – the greatest failing – is when guess work enters the workplace. Of course, it is tedious to apply rules and regulations to procedures you have used for years but the moment that apathy is tolerated then the level of risk accelerates and, of course, it is the simplest, most straightforward work that is often the most vulnerable.

If you cut corners you introduce risk, and not just to yourself but also those working alongside you. If you have completed the same task many times you may come to believe you can undertake it with your eyes closed – but that is when you prejudice your own life and that of your colleagues. If ‘an idiot could do it’ don’t let him! Records show that workplace accidents are most likely towards the end of the working day when work gets rushed and good practice gives way to carelessness and haste, but we should not accept this as fact but guard against it. IRATA work teams operate to procedures and methods prescribed in the Association’s International Code of Practice and this has enabled an unblemished record of safe working.

Diligent self-checking is proof of good intentions Self-monitoring of work performance does not, in itself, bring in new orders, but the pride in, and the regular demonstration of, a safety culture will result in a performance that will. Every member company of IRATA International is required to submit work statistics throughout the year, and these reports are checked when IRATA auditors visit these businesses. The figures provided are handed directly and without amendment to a senior expert in

Reaching new heights of excellence in scaffolding n

Founded in 1945, the National Access and Scaffolding Confederation (NASC) membership now accounts for a significant share of the UK’s total industry workload and is increasingly making its mark in Europe. Members operate from locations throughout the UK. The NASC operates a strict policy of full compliance to all new legislation and its own code of conduct. Through their annual membership audit the organisation ensures that its members uphold best practice as professionals. This means they do not look for shortcuts on safety, which could put lives at risk. The training, qualifications and experience that NASC members offer are recognised throughout the world.

Successful candidates of the Construction Industry Scaffolder Record Scheme are also awarded a National Vocational Qualification (NVQ). These are both held in very high regard within the industry and offer full registration to the Construction Skills Certification Scheme (CSCS) – the industry’s largest skills register and the benchmark for skills quality. All member companies of the NASC offer this training which involves periods of on-site experience, courses in training centres and an outward-bound course.

Training has become the most important aspect within the industry for any employer and two schemes have been created by the NASC. Both of these schemes lead to joint qualifications under the CISRS – Construction Industry Scaffolders Record Scheme and the NVQ/SVQ. q

Delivering expertise in the use of powered access equipment

n

The International Powered Access Federation (IPAF) promotes the safe and effective use of powered access equipment worldwide in the widest sense - through providing technical advice and information and influencing and interpreting legislation and standards through its safety initiatives and training programmes.

It is a not-for-profit organisation owned by its members who include manufacturers, rental companies, contractors and users.

Training in the use of work equipment is required by most health and safety legislation and work at height regulations. Employers are obliged to train employees. The IPAF training programme for platform operators was developed by leading industry professionals.

More than 80,000 operators are trained each year through a worldwide network of over 400 training centres. Successful trainees receive a PAL Card (Powered Access Licence), a safety guide, a log book and a certificate.

IPAF itself does not provide training – this is provided by approved training centres, mostly manufacturer and rental members of IPAF. Approved training centres set the course fees independently for training provided and are regularly audited by IPAF. Class sizes are kept small and courses generally last one to two days and are a mixture of theory and practice, with a written and a practical test. q

this field who is then allowed to write the report that he wishes to and pass this back to the Association for publication. The IRATA Work and Safety Analysis is published every year and is openly available to anyone.

Over the years of this report being published it has not needed to report a single death of IRATA personnel whilst working on rope and has recorded an incident rate that is far below the national and international rates in the work-at-height sector.

IRATA International has taken its work around the world and into many industry sectors. In doing so it has brought this safety ethic to nations who did not previously have a developed safety culture and yet its training regime and safe working procedures have delivered fresh belief in doing things right.

But what can rope access do for you?

We should perhaps first look at some fundamental benefits that you acquire when you use rope access. Firstly, you have the advantage of a quick set-up and dismantle process that you cannot often enjoy with other means of access. Rope access teams arrive with just their ropes and, assuming they have assessed the work situation already, they can be at work within minutes of arriving on site as there is no machinery or access hardware to manoeuvre into place. Similarly, they can vacate the work area in very short time and, perhaps importantly for you, leave no equipment or machinery in place overnight and so avoid any security risk and the obstruction of paths, roads and entrances.

Before, during and after their work IRATA rope access workers deliver the much-prized ‘minimal environmental footprint’ because they need no motive power. They also require modest exclusion zones so are unlikely to affect motor or pedestrian traffic and will not require the chairman’s parking space! And the range of work they can do is vast, as evidenced by the fact that you are able to view IRATA personnel at work not only on Big Ben or Heathrow Airport but also on small projects in towns and industrial sites.

They tackle a limitless range of work that needs effective and safe methods of access to get to the worksite and then manage the work required with a safety-first philosophy and skilled expertise.

IRATA teams work on many of the world’s great iconic sites, but they are equally at home undertaking more modest tasks where inspection, testing, repair, maintenance and cleaning work can be completed without the need to build an access structure or occupy a disruptive amount of ground space.

When employing IRATA rope access teams clients have the ‘comfort blanket’ that is an unblemished and longstanding record of safe working. What more could you ask for? q * A list of IRATA member companies and the documents they work to are available at www.irata.org

One-stop access to training expertise n

Founded in 1974, the Prefabricated Access Suppliers’ and Manufacturers’ Association (PASMA), is the recognised focus and authority for mobile access towers.

As such it advances safety, standards and best practice across a wide range of sectors and represents the interests of manufacturers, suppliers, specifiers and users.

PASMA is committed to the highest standards of practice and as such it operates the industry standard training scheme – training thousands of delegates each year – through a select network of approved training centres that have access to a wealth of resources, knowledge and

support. PASMA trained around 50,000 delegates in 2010.

In addition to the renowned Towers for Users course, the association also delivers a range of specialist courses including Low Level, Work at Height (Essentials) and Towers for Managers. These courses enjoy an enviable reputation amongst management and health and safety practitioners, who seek objective proof of competence for staff engaged in the assembly, use, inspection and dismantling of towers.

Delegates attending these courses receive a course content booklet and PASMA Code of Practice, together with a PASMA certificate and photocard for the relevant level that is valid for five years. q

CAI

stands for proven professionalism n

The Confederation of Aerial Industries (CAI) is the recognised body for the aerial and satellite industry. The CAI is committed to raising standards within the industry – the criteria for membership of the organisation is extremely high, so that the consumer is assured of a quality installation when using a member.

One of the many membership requirements is that any installing member company will agree to the examination and test of any equipment manufactured or supplied, the inspection of any installation or investigation into conduct which could have a detrimental effect on the reputation of the CAI or its members.

CAI members only employ qualified personnel whose work is monitored by an inspector. If a CAI member is undergoing inspection, it may be that the CAI inspector will wish to accompany them to view their installing capabilities. This would be at no extra charge to the customer. It is, however, within the rights of the customer to refuse permission for the installation to be inspected.

All CAI members guarantee their installations for a minimum of 12 months. In addition to this, the CAI undertakes to back-up this

22 constructionnational spring 2011

guarantee with its own twelve months guarantee, for domestic installations only.

This means that should a CAI member fail to honour their 12 months guarantee on a domestic installation, the consumer can seek redress via the CAI. Provided that the problems are within the realms of the original guarantee, the CAI will arrange to have the work corrected at no extra cost to the consumer.

In addition, all CAI members are required to work to the exacting standards laid down in the CAI’s strict Codes of Practice.

CAI members should carry identity cards that clearly state their name and company details together with a photograph. If you are in any doubt about the validity of an installer, ring the CAI on 01923 803030 during normal office hours.

All CAI members are required to have full insurance cover to cover all aspects of their business. Most importantly there is a minimum requirement of ÂŁ2,000,000 for public liability insurance. This gives the consumer total peace of mind before the company even commences work. Through their insurance partners, Jelf Insurance Brokers Ltd, the CAI offers uniquely tailored insurance to meet the needs of the industry that is not generally available elsewhere, and at a competitive price.

If a customer is unhappy with the standard of workmanship carried out by a CAI registered installer, or indeed is dissatisfied with any aspect of the job, the CAI has an official complaints procedure. The CAI will fully investigate any complaint that it receives against one of its members and is empowered to impose sanctions on its members if necessary. q

Raising standards throughout the tiling industry n

Formed in January 2000, The Tile Association (TTA) represents the whole of the UK wall and floor tile industry under the banner of one organisation.

The TTA has more than doubled in size since originally formed and now has more than 750 members, consisting of tiling contractors, fixers, distributors, retailers and manufacturers. Its mission is to promote professionalism and technical standards in the tiling industry, as well as provide technical support to both members and their customers.

The TTA will not accept just any company as a member. Each company, contractor and tiling fixer that wishes to join is carefully checked for financial, technical and service standards. For all projects, large or small, you need confidence that the people taking on the job are skilled professionals. Avoid rogue traders. Enjoy peace of mind.

Check their credentials and make sure they are members of The Tile Association.

At The Tile Association Annual Gala Dinner and Awards Ceremony earlier this year, Ian Crowther, TTA Chairman and Trade Sales & Marketing Director of Johnson Tiles, addressed the industry.

“The major success of The Tile Association is that it brings together companies, individuals, specialists and associated services to create the unified voice for the industry.

“Our technical information and specification details have been updated and we are working to widen the knowledge of the industry on the green attributes of tiles and to ensure that they are an accredited product.

“And tile contracts involving heritage project sites which date pre 1919 will continue only to be available to fixers who hold a Heritage CSCS card – developed by the TTA. “The Tile Association is committed to training and I am pleased to announce that, in response to requests from the industry, the TTA has developed an NVQ level one qualification in tiling which will be launched in September this year.

“Training is important for the industry, whether it be for young craft apprentices or to continually update the skills of established tradesmen. London is the venue, in October 2011, for the World Skills Competition when young trade apprentices from all over the world compete for coveted Gold Medals, just as our athletes will do in 2012.

All the practical trades are represented at the competition, including tiling.

“Representing The Tile Association in the UK Squad will be Harry Coyle, Johnny Carter, Ian McMahon and Mark Woods, one of whom will go on to represent Britain in London. All four have been made honorary members of The Tile Association for 2011 and 2012. Their commitment to the industry is something of which we should all be proud. The eyes of the world will be on them in October and the industry will be there to support them.

“As most of you know it is less than 500 days to the 2012 London Olympics. I am delighted that projects for the Olympics are being led

by British expertise and British products and that British tile fixers are being used for the facilities at this prestigious event.” q

Cathedral encaustic Panels help create tiled floor wins national award

striking façade for new hospital building n n

The refurbishment of the tiled floor at the Cathedral Church of St. Mary’s, Newcastle has recently won a top award from The Tile Association (TTA), which recognises the outstanding skills involved in the creation of the new, Pugin inspired, tiled floor.

The award for The Best Technical Use of a Tile in a Contract celebrates the skills of tile manufacturer, Craven Dunnill Jackfield, which hand-made the 700m² of encaustic floor tiles using authentic production processes sensitive to heritage buildings, and the precise fixing by P Plunkett Tiling Contractors, which involved intricate workmanship to accommodate the architectural features of the cathedral such as pillars and steps.

The newly installed encaustic and geometric tiled floor at St. Mary’s is unusual in that it introduces new designs to this period building, rather than the more common practice of restoring or reinstalling the originals. The cathedral’s architects created the designs using traditional encaustic patterns from Craven Dunnill Jackfield’s archive catalogue. The specialist tile producer then generated some 50 scaled CAD technical drawings, translating the design into a workable floor plan, and then hand produced the high volume of tiles required in record time. q

The new Critical Care Unit at Belfast’s Royal Victoria Hospital will feature an innovative new curtain walling system, with panels supplied by bespoke architectural panel manufacturer Panel Systems.

The architects, Capita Percy Thomas, specified aluminium composite panels with a metallic silver finish, which are fixed within an extruded aluminium frame. This innovative method of construction allows for the creation of a stunning flush-glazed façade to the building.

This system was developed to meet the needs of building designers looking for an alternative to traditional curtain walling systems, where the composite panels sit in an existing frame, which can often look bulky.

Panel Systems manufactured 1,600m2 of the bespoke panel, which consisted of a 150mm core of mineral fibre lamella, to ensure it offered both acoustic and fire retardant properties.

The panels on this project were toggle fixed onto the curtain walling grid in the same way that a fixed light or opening vent is installed within the system. The opening vents have the same sightlines as the fixed panes, ensuring optimum aesthetics. This offers the architect the option to fit any combination of solid panels, fixed lights or opening vents anywhere within the curtain walling grid without causing any issues with drainage, yet creating an aesthetically pleasing façade.

The panels can be colour matched to suit both internal and external aesthetics. q

Asbestos in Buildings n

Recently the HSE launched their ‘Hidden Killer’ campaign to highlight the danger of exposure to asbestos fibre, particularly to maintenance and other tradesmen when working in buildings. This high profile campaign graphically indicated that around 20 tradesmen per week die as a result of exposure to asbestos and that tradesmen are still being exposed to these risks, even today, mainly due to the fact that they are unaware of the presence of asbestos in their workplace.

The Control of Asbestos Regulations (CAR) 2006 places an explicit duty on those responsible for buildings to manage the risk from asbestos in their property, not only for their own employees but for anyone who may come into contact with it including, of course, any tradesmen employed to carry out any work within the property.

A major requirement of CAR 2006, and subsequently any asbestos management plan, is to inform anyone who may come into contact with it of the presence of asbestos containing materials within the

property and to give those people adequate training in how to manage the risk of exposure. Tradesmen are of course under greater risk as they may inadvertently disturb asbestos during the course of their work.

In February 2010 new guidance to replace MDHS 100 was introduced by the Health & Safety Executive. Titled, Asbestos: The Survey Guide HSG 264, this new publication reduced the number of survey types from three to two and placed more emphasis on the client for the selection of the survey scope. There are now just two types of asbestos survey – Management and Refurbishment. Management replaces the old Type 2 Survey and Refurbishment replaces the old Major Refurbishment/ Demolition Survey.

The starting point of any management plan is to find out if the building contains asbestos materials, to record its location, extent and type and to assess the risk of exposure to asbestos materials on the long term health of anyone who may come into

contact with it. To be sure that you are getting a fully HSG 264 compliant report, only those companies accredited by UKAS (United Kingdom Accreditation Service) for both Inspection ISO/IEC 17020 and Testing ISO/IEC 17025 should be commissioned to undertake the work.

A management survey will give you all the information you need to produce your management plan and to risk assess all asbestos containing materials detected in accordance with an internationally recognised algorithm assessment method, as detailed in HSG 264, together with recommendations as to what is required to make the material safe and protect your workforce from dangerous and unnecessary exposure to asbestos fibre. q Alan Peck, Chief Executive Tersus Consultancy Limited

The new national event for the concrete industry is born n

The UK Concrete Show 2011 promised to bring the industry together and, over two days in Coventry in February, it delivered in style.

Almost 2,200 people across a wide range of disciplines attended the inaugural industry show – they saw 112 exhibitors, an excellent range of demonstrations, top class seminars and lively, hands on workshops. Early estimates are that millions of pounds of business was done at the show.

At the close of the show almost 30 stands had been booked and reserved for the 2012 show with Canadian manufacturer Baylynx confirming that they were increasing the size of their stand 6-fold, so pleased were they by the results they achieved at the show.

A number of companies just visiting this year’s show booked their stands for 2012 immediately – Derbyshire based KVM UK snapped up a 36 square metre stand and industry giant Liebherr have confirmed their intention to take 100 square metres. q

On the following pages we feature two of the innovative new products to feature at the show.

sound investment

A in supreme, lasting quality n

Offering superb sound quality, unmatched by any other material, is the new hi-fi concrete loudspeaker system skilfully designed and built for the connoisseur by Concretespeakers.co.uk – a small-scale family concern producing hand built and fully sound tested speaker systems to order.

The purpose of a loudspeaker system is to deliver as pure a sound as possible. This can only be achieved if there is sufficient ‘stiffness’ in the speaker housing to eliminate vibration from the cabinet walls. Many conventional designs use wood-based composites which are economical but not always successful acoustically. Recent attempts have used polymers and metals in a bid to solve this problem which, though expensive, do not come close the superb damping properties of concrete.

Concrete is very dense, significantly reducing cabinet vibration. In addition, the cabinet walls are moulded in one piece, giving rigidity to the cabinet structure. Not only does this rigid structure allow the drive units to perform at the optimum level without distortion, but the strength of concrete increases with time, giving you a product that improves with age.

The idea for the ‘concretespeaker’ was initially developed by company founder Gavin Alexander, while studying design technology at Goldsmiths College, London in the 70’s.

Gavin built his first pair of concrete speaker cabinets as his solution for a ‘sound’ project.

He applied prior knowledge of the versatility of concrete as a material and was very impressed with the clarity and richness of sound achieved.

Following further studies at the Cement and Concrete Association in Slough, Gavin built an improved system in 1982 and has enjoyed listening to recorded music through these loudspeakers for nearly 30 years. Although he has upgraded other hi-fi components in his sound system his concrete loudspeakers remain constant, their sound quality out-performing many well-known brands costing thousands!

His current design, the AL200BR, had been evolving for a little over three years when his son James, a musician and sound engineer, persuaded Gavin to update his original ‘box-like’ design to give it a more contemporary appearance.

Happy to accept this challenge, Gavin began designing a range of cabinets that would appeal to a new generation of music lovers. He researched and tested a range of cement and aggregate formulations that would give the ‘marblelike’ appearance he was looking for – and the the AL200BR was born!

This model has been made from carefully selected, high quality audio components that deliver a sound quality equal to products retailing at least double the price on the high street. Ingredients for the concrete mix have been carefully chosen to enhance the visual as well as the sound quality.

Many hours have also been dedicated towards the design and manufacture of a re-usable mould that ensures a consistantly high quality ‘finish’. The speakers are available in a choice of colours and finishes to meet your individual needs – see website for details. The company also offers a delivery and setting-up service throughout mainland UK. q Company founder Gavin Alexander (top) and his musician son James

Pride in the Job Supreme Award winners 2010 January saw the culmination of the 2010 NHBC Pride in the Job awards when 600 guests attended a presentation ceremony and dinner at the exclusive Park Plaza Westminster Bridge Hotel in London.

This was the 30th anniversary of the awards which celebrate and recognise the very best site managers from the house house building industry and have been fundamental in raising standards for new house buyers.

The Supreme Award winners in each of the four categories were presented with their awards by BBC broadcast journalist Kate Silverton.

n

Tony Boulter, winner of the small category award, said he enjoyed the personal satisfaction of producing quality homes on his development, School Hill in Truro, and the feeling that his hard work and efforts had paid off with the Supreme Award. This is the first time that Tony has become a Supreme Winner.

His site is a development of bungalows all built to a high standard.

The judges commented that each unit had exceptional external finishes and the quality of the work to the boundary and retaining walls ‘couldn’t have been better’.

Tony has been in the construction industry since leaving school and formed his own building firm in 1973, before forming his present company, Boulter Smith Ltd, in 1980.

NHBC Chief Executive, Imtiaz Farookhi, said at the ceremony: “For 30 years, Pride in the Job has been recognising and rewarding site managers who consistently build to high standards.

Climate Energy Solutions raise the bar in solid wall insulation e Climate Energy Solutions (CE Solutions) is a fully accredited insulation installer. Historically offering cavity and loft insulation, their exclusive UK distribution agreement with Wall–Reform® has enabled them to offer solid wall insulation using one of the best systems on the market.

CE Solutions has always taken pride in their customer service by using experienced and qualified installers who are constantly praised for their workmanship and people skills. Not content with standard installer accreditations they moved forward gaining CHAS (Contractors Health & Safety) and the additional SAFE contractor accreditation which is recognised as the fastest growing health and safety assessment scheme in the UK. The decision to apply for the SAFE contractor accreditation was driven by the need for a uniform standard across the business.

Managing Director, Phil McGrory commented “The work that we have been involved with from our start up in 2009 ranges from a one off domestic job to a nine storey block at Southend General Hospital. We felt that this would complement our existing CHAS accreditation and help to promote us to other nationwide businesses”.

He continued, “The additional accreditation has enhanced the company’s ability to attract new contracts and shows our commitment to safety which will be viewed positively by insurers when the company liability policy is up for renewal.”

John Kinge, Head of Risk at SAFE contractor, said “Major organisations can no longer run the risk of employing contractors who are not able to prove that they have sound health and safety policies. More companies need to understand the importance of adopting good risk management in the way that Climate Energy Solutions has done. The firm’s high standard has set an example, which hopefully will be followed by other companies within the sector.”

CE Solutions also recently took the opportunity to create a 7 minute film with the Energy Saving Trust (EST) to be part of their, ‘How to…’ series of documentaries focusing on showcasing their solid wall offer.

The interview and commercial presentations were screened on SKY in February and again March, with a potential audience of 22 million viewers, in over 9 million homes. The film is also available through the

BEFORE

Media Centre of their website at www.ce-solutions.org.uk.

The film illustrates how the Wall–Reform® system works and the amazing number of finishes it comes in. Wall–Reform® is a 15mm solid wall render system that, when attached to a 60mm phenolic board, achieves a U-Value of less than 0.3 W\m².k which conforms to the latest Building Regulations.

It is widely recognised as the best thermal plaster/render product available and it has been confirmed by many building control departments (LABC) that thermal products must be specified over non thermal to obtain the best standard technically, functionally and economically.

Wall–Reform® has two full BBA certificates, one as a thermal plaster/ render and another as a remedial plaster following a damp course.

It also helps reduce condensation and was specifically developed to improve the living conditions for those living in solid wall properties.

However, it can be used wherever any wall is being plastered or rendered and will increase the thermal element even when applied at 10mm thickness.

All C E Solutions’ thermal products have full EST, CESP and CERT approval. Phil McGrory felt that the creation and broadcasting of the documentary was a great opportunity to show the country they had solved the problem of solid walls insulation. He said, “We are now able to help people in traditionally harder to treat properties to save energy, money and the environment. I am also pleased to announce that we will be opening a training centre in Essex to complement the training offered by Wall Transform® in North Yorkshire.

CE Solutions opened the first Solid Wall Training Academy in Braintree, Essex to train installers in the art of Wall–Reform® application. The purpose built centre is available to all accredited installers to ensure that Wall–Reform® is installed to the highest standards in accordance with BBA and their own stringent specifications. n • If you are interested in training or finding out more about purchasing Wall–Reform® contact Climate Energy Solutions on 0800 980 4749 or 01376 555999.

Why insulation is key to the UK’s carbon emissions target

e

With homes producing over a quarter of the UK’s carbon emissions, the onus on reducing their carbon footprint has never been greater for householders and it is a priority Government issue too.

The way a building is constructed, insulated, ventilated and the type of fuel used, all contribute to its carbon emissions.

It is a worrying fact that, for over half of all homes in the UK, a significant proportion of the money spent on energy is literally being thrown out of the window as a result of inadequate levels of insulation, with around 50% of the heat being lost through the roof and walls.

The National Insulation Association (NIA) is a not for profit organisation representing over 90% of the home insulation industry in the UK. As a membership organisation, it actively supports the Government’s accelerated programme for insulation and its intention to raise awareness not only of the amount of CO2 lost through inadequate insulation, but also the amount of money that householders can save by having their homes properly insulated.

Before (left) and after the application of Envirowall’s Envirobrick external render system announced in June last year will focus on whole house eco-makeovers. However, SWI will have to increase dramatically if the Government is to hit its target by 2020. In fact, at a recent seminar held by the NIA, an industry expert stated that: “A figure of 200,000 properties per year would have to be completed if the Government is to hit its target by 2020.” More and more individuals are now starting to recognise the advantages of SWI and there are many cost-effective solutions available.

Solid Wall Insulation

The Solutions

The UK’s housing stock is estimated at approximately 24.5 million dwellings and 36% are made up of non-cavity wall construction – solid brick, solid stone, pre1944 timber frame and non-traditional, i.e. concrete, construction. These types of buildings lose more heat and energy than any other type of construction – a worrying fact when it is estimated that around seven million properties with solid walls have little or no insulation. While many local authorities, housing associations, private landlords and home owners have been concentrating on filling cavities to achieve their carbon savings, improving the thermal efficiency of solid-wall properties has largely been ignored. This is primarily because the solutions are deemed to be more expensive and cause greater disruption, hence the reason that these types of dwellings are referred to as ‘Hard to treat Homes’. This is not actually correct, they are not hard to treat, just more expensive to insulate compared to cavity wall insulation and loft insulation. However the subsequent energy savings are significantly higher.

Improving the thermal efficiency of solid wall properties is therefore an area which has massive potential for the future, particularly as little work has been carried out to date.

Around 25,000 properties a year currently receive solid wall insulation (SWI) and the Government’s new ‘Green Deal Scheme’

Solid walls can be insulated with either External Wall Insulation (EWI) or Internal Wall Insulation (IWI) and either option will greatly increase comfort, while also reducing energy bills and the associated environmental impact.

IWI typically consists of either dry lining in the form of flexible thermal linings (commonly known as thermal wallpaper), laminated insulating plasterboard (known as thermal board) or a built-up system using fibrous insulation such as mineral wool held in place using a studwork frame.

Flexible thermal linings come on a roll and are applied like wallpaper and, with some at only 10mm thick, will not cause significant disruption during installation.

These products can be applied to ceilings as well as walls and provide a solution for properties without a loft space as well as those with solid walls. It can also be applied to the underside of floorboards in a cellar/ basement. It is applied with a special adhesive using a roller or a brush and can be easily cut to size using wallpaper shears or scissors.

Once the product has been applied it can be painted, papered or even tiled. These products are only applied to the exterior facing interior walls of the property.

Another solution is laminated insulated plasterboard which normally replaces existing lath and plaster and is fixed directly to the

existing brick. Depending on the system, thermal boards can either be screwed or glued, using a dry wall adhesive, directly onto the brick work just like standard plaster board. It has the advantage that it can be installed room by room with the tenants in situ. It increases internal surface temperature within a room and also improves response to heating input when heated intermittently. It has the lowest thermal conductivity available and allows installation on damp surfaces without drying periods as it is hydrophobic.

EWI comprises of an insulation layer fixed to the existing wall, with a protective render or decorative finish. Dry cladding offers a wide range of finishes such as timber panels, stone or clay tiles, brick slips (brick effect finish) or aluminium panels. EWI increases the thermal quality of the building – particularly relevant when refurbishing non-traditional housing. It also overcomes moisture and condensation issues and protects the existing building envelope. It can reduce heating bills by up to 25% as well as greatly improving the appearance of the building.

EWI is a tried and tested method of upgrading the thermal performance and external appearance of existing properties which are literally transformed into warm, energy efficient and attractive homes and buildings. Improving appearance is of particular significance to many local authorities targeting housing projects in poorer areas. Adding EWI on a whole street basis will raise residents’ morale and give them a sense of pride in their community.

There are many other benefits of EWI including the fact that no living space is lost. There is minimum disruption for the residents as the work can be carried out while they are in their homes and there is no risk of condensation within the property as it is moved to the outside of the system that is being put in place. Also there is minimal maintenance once installed. n

Wood recycling sector looks forward to an exciting future

e

As we in the UK move towards a more sustainable society we must re-use and recycle more and landfill less, say the Wood Recyclers’ Association (WRA) as it celebrates its 10th anniversary.

As landfill taxes, landfill operator and haulage costs continue to rise, and packaging waste regulations become more stringent, the recycling of materials, including wood, assumes an everincreasing importance. The wood recycling sector therefore looks forward to an exciting future with enormous potential for expansion.

Set up in 2001, the WRA now has 75 member companies and represents the interests of the wood recycling sector to the Government, the Environment Agency and other regulatory authorities in the UK. Meetings of the association are usually held quarterly and are open to all members. Subjects range from trade and potential markets, discussions with the Government’s Waste and Resources Action Programme (WRAP) and packaging waste, through to regulatory, environmental and publicity issues.

The WRA published the Wood Packaging Protocol to more accurately calculate the amount of packaging being processed. It has also produced the Wood Recyclers’ Code of Practice, designed to raise operational, quality, environmental and health and safety standards in the sector.

The WRA is currently working with the Environment Agency and WRAP to develop a Quality Protocol for post-industrial wood. Once achieved, this Quality Protocol will define the point at which the wood which members process ceases to be a waste and becomes a product.

In parallel with the Quality Protocol development, the WRA is working with WRAP and BSI to develop a publicly available specification – PAS111 – for post-industrial wood. These exciting projects promise to enhance considerably the status and quality of WRA members’ products.

The WRA is a member of the Recycling Industries Alliance, an influential group of eight recycling trade associations set up in 1998 to lobby Government and the Environment Agency on a variety of major issues on behalf of member companies. n

Biomass at Christmas n

Christmas should be a time to sit back and relax with the family – but not for Kevin Thompson and the guys from the biomass-processing department of Cumbria based Thompsons Plant Hire Ltd. For them it was off to a damp and dreary Ayrshire and North Wales to provide holiday cover at both of the UPM CHP boilers and paper mills in Irvine and Shotton for the supply managers UPM Tilhill.

The plants are powered by green energy, through a biomass-fueled power plant, which uses approximately 80 tons of processed biomass per hour. This is usually trucked in from outside, but over the Christmas period the company’s regular suppliers shut down, leaving Thompsons to step in and fill the gap by chipping and handling on site stocks of biomass.

Maintaining production is no small job and requires not only the monster Morbark 4600XL Track Wood Hog but also a Morbark 5048 Drum Chipper. These machines are quite something to behold as they turn huge logs into wood chips in a matter of seconds. Between them, over the Christmas period, they managed to chew their way through 10,000 tons of logs at 25 tons per wagonload – that’s 800 wagons!

The Morbark 4600XL Track Wood Hog Thompsons were the first company in Europe to take delivery of a Morbark 4600XL Track Wood Hog. This massive machine is designed to work in the most inaccessible of locations. Usually found in a remote Scottish forest it has the capacity to produce up to 100 tons per hour of biomass from green brash wood and tree stumps.

Once shredded into biomass it is loaded

onto Thompsons’ fleet of walking floor artic trailers ready for delivery to the client. q OBMtec, specialists in the field of recycling machines, wood chippers and stumpgrinders are importers of Morbark machines for the whole of Europe. For futher information visit www.obmtec-rte.com.

Trenchless technology - the future of construction e Trenchless technology is increasingly accepted worldwide as being more efficient, less disruptive, environmentally friendly and more cost effective than traditional methods.

The UKSTT (United Kingdom Society for Trenchless Technology) is a registered charity involved in the development and promotion of trenchless techniques, sometimes termed no-dig techniques.

Trenchless technology is the science of installing, repairing or renewing underground pipes, ducts and cables using techniques that minimise or eliminate the need for excavation.

The use of such techniques can reduce environmental impact, social costs and at the same time provide economic alternatives to traditional open cut methods of installation, renewal or repair.

The techniques themselves can be broken down into three areas: • Repair and Renovation – including cleaning, localised repair techniques and lining techniques.

• Replacement – including pipebursting, pipe splitting, pipe eating and lead extraction & replacement systems • New Installation – including impact moling, pipe ramming, auger boring & thrust boring, pipe jacking, micro tunnelling, guided rod pushing, guided boring & directional drilling, rock boring, cable pulling and cable blow in systems.

Essential to the success of such methods are training, thorough site survey, planning, material and equipment choice.

The aims and objectives of UKSTT are: • To advance the science and practice of trenchless technology

• for the public benefit.

• To promote education, training, • study and research in the science and practice.

• To encourage the use of trenchless systems for the installation and • repair of underground pipelines, utilities and services.

• To promote the location and mapping of underground services.

• To encourage the development of new trenchless techniques.

• To assist members to maintain and enhance their knowledge, skills • and capabilities in the field of trenchless technology. n

World’s first application of latest pipeline rehabilitation technology

e

Portland, in Dorset, recently saw the world’s first commercial application of the latest development in pipeline rehabilitation technology – the new Melt-In-Place Pipe (MIPP™) system, known as Aqualiner, was installed for Wessex Water by its main rehabilitation contracting partner OnSite Central Ltd. Whilst the project may not be the largest, it was significant for both Portland and Aqualiner Ltd. Using the latest ‘third generation’ commercial system, it was the first ever to be undertaken on a ‘paid for’ basis.

The lining comprised the rehabilitation of just 23m of existing 225mm diameter clay sewer pipe which runs beneath Castle Road at between 1.5 and 2m deep. The work, scheduled to last one day working between manholes with a full traffic flow allowed alongside, would have taken 7-10 days of traditional open cut trenching with huge and unacceptable disruption. In the event, the lining installation process took just over 2 hours.

The Aqualiner process, whilst similar to existing relining systems, differs in some significant aspects. It does not utilise resins or chemicals as part of the lining process, rather it uses a liner material which comprises a combination of glass fibres, for stiffness and strength, and thermoplastic polymer fibres which, after processing, becomes the matrix that surrounds the reinforcing fibres.

This absence of chemicals in the liner process and its standard material content and strength means the Aqualiner system is not only suitable for installation in sewer systems but also pressure pipes, including potable water pipes.

The process is even reversible. By heating the liner to the correct temperature the liner can be removed if required with all the materials being fully recyclable. n

Tapping the earth’s stored energy with a

ground source heat pump e

Ground source heat pumps (GSHPs) are electrically powered systems that tap the stored energy of the greatest solar collector in existence – the earth. These systems use the earth’s relatively constant temperature to provide heating, cooling and hot water for homes and commercial buildings.

Ground source heat pumps can be categorised as having closed or open loops, and those loops can be installed in three ways – horizontally, vertically or in a pond/lake. The type chosen depends on the available land areas and the soil and rock type at the installation site. These factors will help determine the most economical choice for installation of the ground loop.

For closed loop systems, water or antifreeze solution is circulated through plastic pipes buried beneath the earth’s surface. During the winter, the fluid collects heat from the earth and carries it through the system and into the building. During the summer, the system reverses itself to cool the building by pulling heat from the building, carrying it through the system and placing it in the ground. This process creates free hot water in the summer and delivers substantial hot water savings in the winter.

Open loop systems operate on the same principle as closed loop systems and can be installed where an adequate supply of suitable water is available and open discharge is feasible. Benefits similar to the closed loop system are obtained. n

Landfill

Gas to Cash

Assessing the value of landfill gas and advising on its optimum use is one of the specialist services of landfill experts, Coventry based, Automatic Flare Systems (AFS).

AFS uses its mobile flare skid for landfill gas pumping trials to analyse the quantity and composition of landfill gas. Mounted on the skid is a Geotech GA3000 static gas analyser. It monitors the untreated gases downstream from knockout pots before going onward to a flare.

Managing director at AFS, Steve Willacy said, “We want continuous landfill gas monitoring and analysis and use a data logger to record the results from the gas analyser.” The data is auto downloaded to a web page so AFS can inspect it without going to site. At the end of the 12-week pumping trial AFS produces a site assessment report with daily gas readings, gas curves and an assessment of gas quality, type and volume. “We can then advise on how the gas can be best used for power generation, as vehicle fuel, converted to methanol or to biomethane to replace fossil-sourced natural gas – or if no value, how best to flare it.

“We had been using another supplier’s gas analysis equipment for about ten years and had been talking to Geotech about them producing a static gas analyser which suited our operations. With input from us and others, Geotech developed the GA3000 using its existing proven equipment, technology and know how. The GA3000 is doing exactly what we need it to do,” said Steve Willacy.

Since completing its latest pumping trial in Scotland the AFS mobile flare and analysis skid with its GA3000 been moved to Stornoway on the Isle of Lewis to carry out a pumping trial there.

While the GA3000 is working away on a remote Scottish island and its data is being inspected in Coventry, AFS is taking delivery of its next, larger Geotech automated extraction monitoring system (AEMS) with six gas channels for six supply sources, for an export client. n • More from Geotech at: www.geotech.co.uk or from AFS at: www. afs-group.co.uk

Communication is a must Transfer of private drains & sewers

e

The transfer of private drains and sewers is now set for 1st October 2011 and the challenges to all sides of the industry remain immense in what will be the biggest shake up the industry has seen, according to the National Sewerage Association. There is still a tremendous amount of work to be undertaken by Government in finalising regulations and procedures and the clock is ticking.

It will not only launch the water companies into relatively unknown territory, but the nature of the work, volume and need for prompt action will prove a test for Tier One contractors. We would look to all supervising officers acquiring an understanding of the processes involved (there are existing training courses) in order to avoid conflict between parties.

The challenge is in providing an informed call centre, knowledge of the area and sufficient operational vehicles and manpower to provide a rapid response service. Ideally this would involve the myriad of small proven local contractors utilising their local experience. To have a matrix of local contractors instead of a cascading downward series of subcontractors would give control on standards and service. The use of computers to allocate and log work would make a payment structure viable – it has been done before.

All sides of the industry need to be proactive and urgently participate in discussion with an open mind and to come up with innovative solutions to ensure that small companies, with well trained staff, can have a future and not be lost to the industry. Their experience is going to be vital to a smooth and invisible transfer.

It will be in the industry’s best interest if rates are set at a realistic level to maintain a cost efficient standard of work with well maintained equipment. There is still a warning in the old adage that ‘if you pay peanuts you get monkeys’. This industry has striven to set standards in safety and quality of work – let us not renege on the precedent set.

The lowest price can only be cost effective if all the criteria are met as laid down in the various, long established, model contract documents.

Where work has to be repeated due to the contractor taking short cuts, or not having the necessary experience in a process, could result in the lowest tender, on evaluation, proving more expensive than other tenderers with a proven track record. For peace of mind, all the appropriate training should have been undertaken by staff currently working for the contractor before any tender is considered.

At the recent meeting of the Private Sewer Forum, chaired by The Society of British Water and Wastewater Industries, it became even more obvious that communication is the key to a successful outcome.

Those of us involved in the contracting side of the industry have

10 environmentalbuild spring 2011 40 constructionnational spring 2011

been concerned about member companies working in the sector and how they can best ‘sell’ their services and skills to those who will be supervising the work in the future.

It would be to the benefit of the Tier One contractors if they were seen to be proactive in setting up meetings, much as some water companies have, with interested providers to discuss the problems experienced in the private sector and how working in partnership might be of benefit.

UK Drainage Protocol, who joined the meeting as guests, highlighted the lack of communication between local authorities and water companies following an online survey. They are unsure what their role will be post transfer and in the case of environmental threat, where they still have responsibility for resolution. Clarity of process is required as Section 59 notices for enforcement of repairs and recharging provisions will be repealed.

The message of change still has to reach many of the small contractors working in the private drainage sector throughout the country. Trade magazines, Government initiatives and trade associations have been trying to get the message out for several years with limited success. The general public needs to be made aware of the change, where applicable, and what procedures will be in place.

It can be seen how important communication is, and will be, in making the transfer of private drains and sewers a success. The tardiness in finalising the regulations and protocols for the transfer continues to hinder, in part, the communication process. Clarity of communication is required between the water companies and their support partners in local government and the operational processes and discussions need to take place now. n

Raising standards in the sewerage industry

e

The National Sewerage Association (NSA) has established its credentials within the sewerage industry, having been formed in 1996 to represent the interests of companies associated with the survey, operation, maintenance and renovation of sewers, drains and pipelines.

The NSA has representatives on several standards committees and liaises with other trade bodies on subjects of mutual interest. Its members are generally engaged in the inspection and maintenance of drainage and sewerage systems working to nationally accepted standards. Some specialise whilst others provide a broader range of services.

Members are expected to meet high criteria for staff training in the hostile environment in which they operate. Of critical importance are quality systems developed by members to ensure that reported data is to the highest possible standards. Reassessment criteria are being developed both for operatives and contractor members and these will be introduced so as to ensure that the high levels presently in place are upheld and improved. n

Hospital air conditioning powered by high efficiency natural gas engines

e

A state-of-the-art air conditioning system powered by high efficiency natural gas engines is providing low carbon cooling and heating at Scunthorpe General Hospital.

The system uses seven Sanyo gas-powered heat pump (GHP) chillers to supply chilled water to air handling units serving a suite of operating theatres.

It replaced two aging Trane chillers, based on hermetic scroll compressors running on the R22 refrigeration system. The internally located, ducted air-cooled machines, each originally rated at 165 kW, had been installed in 1991 and had become inefficient and expensive to run.

Consultant Pick Everard carried out an evaluation of several possible replacement options, including a traditional electric chiller and compact turbo-based technology.

Jeff Fleming, who headed the project for Pick Everard, said: “A key issue at the site was that there was no headroom on the electricity supply. Cooling loads had grown since the original chillers were installed, and replacing with a larger conventional electric chiller would have required a big investment in additional power supply.

“The Sanyo gas-engine driven heat pumps supplied by Oceanair (UK) Ltd not only provided a way round the power problem, they are a highly energy efficient solution. Our studies showed that in terms of life-time costs, energy consumption and carbon emissions, they come out well ahead of comparable electric systems.”

A further benefit of the Sanyo units, he says, is their low noise which makes them ideal for use in hospitals. Noise was likely to be a planning issue on the project, and the GHP units exceeded any potential restrictions. “They are exceptionally quiet in operation. You have to actually put your ear to the units to hear they are running at all,” he says.

The seven GHP units, each with an output of 56kW, were chosen from the Sanyo range for their optimum efficiency in order to minimise the hospital’s liability under carbon reduction legislation.

A further benefit of the multiple system is resilience compared with a single large chiller. If one unit is out of action, there is capacity to provide continuity of service. In the case of a conventional chiller installation, breakdown can cause disruption and affect cooling to the building.

The power advantages of the GHP units extend to a much lower startup current than standard electric chillers. As the process mirrors ignition in a modern vehicle engine, a few dozen Amps are all that are required for start-up rather than several hundred Amps for an electric chiller.

In winter, the heat pump cycle is reversed, providing high efficiency heating to operating theatres. As heating was previously supplied by inefficient steam heater batteries, this is saving significant additional

cost, Mr Fleming reports.

Each chiller produces an additional 18kW of waste heat that can be harnessed for use in generating hot water for the hospital’s domestic supply.

Each of the R410A chillers has its own separate refrigerant-to-water heat exchanger within the building, eliminating the presence of water on the roof and overcoming the need for trace heating, anti-freeze and water treatment chemicals.

Mr Fleming says: “Another bonus with the Sanyo system is that we only used one system pump compared to conventional chillers that usually require an additional chiller shunt pump or heat rejection pumps, which have a significant electrical power requirement.”

Servicing is highly economical, with engines requiring servicing every 10,500 hours, which equates to between two and three years.

Jeff Fleming says: “The Sanyo GHP units provided a superb solution that perfectly meets the requirements of the project. The technical support from Oceanair has been excellent throughout. They are the experts when it comes to Sanyo GHP technology, and helped train the hospital engineers in commissioning and optimising the systems.”

“I would have no hesitation in using the Sanyo GHP system again and look forward to working with the Oceanair team.”

Tony Evanson of Oceanair UK Ltd said: “The project is a brilliant example of how a modern GHP system can deliver in all areas – efficiency, power, servicing, low noise and low cost of ownership over the lifetime of the plant. It makes the case for GHP loud and clear. It is a technology that, in the right application, simply can’t be beaten.” n
