CASE STUDY

Providing

protection Thompsons of Prudhoe have worked closely with Scott Safety on a trial of the Phantom Vision

A

family owned business based in Northumberland, Thompsons of Prudhoe has over 60 years’ experience in the demolition and construction industry, often being required to deliver technically challenging projects in a safe and professional environment.

The company undertakes every aspect of demolition, dismantling,

2 Construction & Civil Engineering

decommissioning and earthworks projects, from asbestos removal, decontamination and asset recovery, right through to waste management, recycling and ground remediation.

The company is fully licensed and experienced in all aspects of asbestos removal. Teams work to the highest standards within this high risk and increasingly regulated industry. As a long-standing member of ARCA, Thompsons

ensures that all types of asbestos are removed safely and effectively, eliminating this hazardous material from demolition and construction projects. Its staff are experienced in removing asbestos products from a wide variety of different structures, including insulated flooring and roofing, through to pipework and internal fittings and fixtures.

With workers safety a top priority, Thompsons has invested in the

best safety equipment to enable its staff to work effectively and safely in asbestos contaminated environments. Reliability and ease of use are key factors when it comes to choosing respiratory protective equipment and other essential personal protective equipment for workers in this industry.

Thompsons has developed an excellent working relationship with Scott Safety through the company’s

regional manager and over the last ten years has bought a range of respiratory protection products including the Proflow, Powerpak and Phantom Vision, a powered air purifying respirator (PAPR).

In fact, when the Phantom Vision was introduced, Thompsons was chosen as a trial site for the new product.

Scott Safety spent time with the Thompson team working through

risk assessments to ascertain the right level of protection required.

The company provided intensive training on the use of the Phantom Vision, assessing its use in real conditions and gaining direct feedback from the user on issues such as comfort and ease of operation.

The launch of the Phantom Vision

Construction & Civil Engineering 3

signalled a major technological advance for mask mounted powered respirators; providing greater comfort and ease of operation for users requiring powered or nonpowered full facemask protection.

With its motor mounted inside the facemask, Phantom Vision significantly reduces the burden for the user and greatly simplifies the decontamination process after use. The design was developed specifically to meet the requirements raised during the consultation process, with a focus on low through life operating costs and improved user experience.

Feedback from the team at Thompsons certainly bears out Scott Safety’s claim to have designed a powered respirator that combines both comfort and reliability.

“Comfort is a big issue if you have to wear a PAPR for up to eight hours a day,” says Richard Jackson, head buyer at Thompsons. “Since the introduction of Phantom Vision, our teams feel they can work for greater periods of time due to longer lasting batteries and because the unit is lighter and easier to use, they suffer less from fatigue and can get in and out of cramped spaces more easily.

“The styling and look of the mask is important and the Vision ticks all the boxes,” he continues. “Scott Safety products provide comfort and reliability in the very hard working environments our teams operate in and I need to be certain that they are safe. It is easy to clean and maintain, therefore the Phantom Vision is now the only choice for us.”

After working in asbestos environments, decontamination is an essential process to ensure that asbestos fibres are not taken out of the secured environment on clothing or equipment, which might expose others who are unprotected. The decontamination procedures for users of the Phantom Vision are clearly set out in the user manuals. It is fully shower proof and should be worn throughout the decontamination process. All components can be wiped clean and

“With all the correct procedures, training and protective equipment in place, Thompsons is quite rightly proud of its reputation for completing projects safely and efficiently ”

technical guidance on this process is provided.

The asbestos removal teams receive on-going training to ensure that they are removing asbestos in a way, which is safe for both themselves and the public. Thompsons of Prudhoe invests heavily in the latest safety equipment and protective clothing, replacing it regularly to ensure the utmost effectiveness. All asbestos waste is packaged, marked and disposed of safely and in line with government guidelines. When asbestos removal projects are completed, Thompsons works with an independent and approved analytical company to provide the documentation and reoccupation certification required for its

customers’ records.

With all the correct procedures, training and protective equipment in place, Thompsons is quite rightly proud of its reputation for completing projects safely and efficiently. Richard Jackson concludes: “Working with Scott Safety, one of the world’s leading manufacturers of respiratory protective equipment, means that we can be confident we are providing the very best protection for our staff. We work in tough, sometimes dangerous environments and Scott Safety has the experience and technical knowledge to help keep our workers safe.” m

Simple route map

Thinking creatively A recent report by the London Health Commission found that £50m-£60m was being spent annually on maintaining NHS buildings that were either not used or not fit for purpose, prompting experts at WSP, the firm behind the engineering design for the Shard, to analyse the opportunities for redeveloping the real estate.

WSP says that by building apartments above NHS buildings you could provide a minimum of 77,000 new homes in London. This would represent almost 20 per cent of the 400,000 homes needed in the next decade according to the Mayor, with the added benefit of being able to redevelop ageing and unused healthcare facilities at the same time.

WSP’s estimation is based on their analysis of 79 individual existing NHS buildings in London, allowing for 100m² per apartment and using a mixed height overbuild development strategy, with a combination of six, 12, and 18 storeys. It only considers hospital buildings without A&E

facilities, which would cause specific planning and construction issues. If all the new residential buildings included 18 extra storeys the strategy could provide 118,000 homes, more than a quarter of the estimated need.

Director at WSP Bill Price said: “If private developers were allowed to invest in this land it would help plug the gap for more homes in London as well as provide stateof-the-art healthcare facilities to replace those that need a facelift or are not currently being used.

Obviously there are a few hurdles that would need tackling but this is done elsewhere in the world, for example the US, and there’s certainly no technical reason why it couldn’t be done.

“However the point is not that we should go out and redevelop every hospital into an apartment block, but that we need to start thinking creatively about our housing woes, challenging the status quo and looking at how we use the land available to us.”

The Travis Perkins Group, through Sustainable Building Solutions (SBS), has created a simple menu of options to help house-builders efficiently achieve the new Part L Building Regulations by matching the right energy solution with the right build fabric.

Over the last two years, SBS developed the fabric-first element of the solution: a series of specified technical drawings for brick and block construction, using everyday building materials and techniques.

With the introduction of the new Part L documentation in April, SBS launched a menu of options demonstrating how the drawings work with various heating, ventilation and renewables products, and the air tightness level required by each option. This allows builders to cater for specific customer and site requirements.

Lee Jackson, head of technical services at Travis Perkins, said: “With each new change in Building Regulations, there are plenty of myths created around how restrictive and difficult they are to achieve. With the right technical advice and fabric first principles it’s possible to simply build to the regulations with standard masonry construction to a total wall thickness of 300mm, with very little new equipment.”

Shedding light Mitie has been awarded a multi-million pound lighting maintenance contract by Tesco. This is the largest contract of its kind in the UK. The four year contract will see Mitie deliver lighting maintenance and repairs to Tesco’s 929 stores throughout the UK, and emergency lighting tests in 1500 Tesco Express stores.

Mitie was chosen for its experience delivering maintenance and energy savings, its national capability, and innovative approach.

Peter Mosley, managing director of Mitie’s Technical Facilities Management business, said: “We’re delighted to have been awarded the UK’s largest lighting maintenance contract; an achievement that highlights the significant growth and capability of our lighting business. Mitie’s service ethos and commitment to excellence are a good cultural fit with Tesco’s, and I look forward to continuing to grow our successful partnership.”

With over 35 years’ experience in the roofing industry, Richard Lowe has seen a whole host of design and legislative changes adopted over the years. Here he discusses one current hot topic in roofing systems - the issue of fragility

I

n the past few of months there have been a string of reports of serious injuries and in some cases, fatalities, due to some roofing contractors failing to control the risk of workers falling through fragile roof materials.

These news headlines have placed the issue of non-fragility under the spotlight within both the roofing industry and wider construction professionals too.

The construction of the roof is undoubtedly one of the most

6 Construction & Civil Engineering

Richard Lowe

hazardous operations in a commercial build process because of the potential for falls or material dropping onto people below.

Coupled with that, we’ve seen demand for designing with glass soar in recent years, with stylish, contemporary structures becoming ‘the norm’ rather than a luxury.

Installing large expanses of glass comes with its own challenges over and above easier to manhandle or lighter weight materials such as polycarbonates, for those

working on-site.

With architects, designers and building owners keen to maximise natural light within a wide range of sectors and building projects, this issue of non-fragility must be addressed hand in hand with this shift towards bolder affordable design and general sustainability of materials.

The National Association of Rooflight Manufacturers (NARM) states that the, “… roofing contractor must plan and

document a safe system of work before starting construction. This must take into account if any of the roof assembly will be fragile until fully fixed.” NARM also states that metal roofing systems, together with appropriate rooflights, “… can be designed to be non-fragile even after the first fix of lining out.

However until the systems are fully fixed, both metal and rooflights must be regarded as fragile.”

When specifying rooflights, designers should carefully consider

robustness and strength of the glazing required, and the possible dangers of employees working at heights within this context of fragility. As in all construction work, good safety standards are essential to prevent accidents. In accordance with the Health and Safety at Work Act and the Construction (Design and Management) Regulations 2007 (CDM), buildings should now be designed with safety in mind, not only for the construction period, but throughout the normal

life of the building. This must include considering the safety of people involved in maintenance and repair work - and even demolition. For example, it may mean providing permanent access to the roof and walkways.

The HSE document HSG 33 Safety in Roof Work refers specifically to fragile rooflights as an example of a potential hazard which should be considered during design and construction, and “…rooflights should be designed to project above the

Construction & Civil Engineering 7

EQUIPMENT

plane of the roof so that they cannot be walked upon…” – both of which are also key considerations stated by NARM. Like all good quality rooflight manufacturers in the UK, here at Xtralite we’ve followed a strict and comprehensive testing system for many years to ensure non-fragility of the specified glazing. The original Advisory Committee of Roofsaftey (ACR) test for Non-Fragility arose in the late 1990’s following concerns expressed by the HSE and the roofing industry about the lack of guidance on what constitutes as a fragile roof assembly. In more recent times, the Centre for Window and Cladding Technology (CWCT) has introduced new guidelines and testing for rooflight manufacturers, taking into account the possibility of any part of the roof assembly being fragile until fully fixed. The CWCT test is currently best practice as opposed to mandatory, and involves breaking a standard rooflight to assess its strength and robustness.

While undertaking this comes at a cost to manufacturers, many reputable rooflight manufacturers undertake them in contribution to creating safe, best practice solutions and for our customers, it means they benefit from an added

8 Construction & Civil Engineering

“Like all good quality rooflight manufacturers in the UK, here at Xtralite we’ve followed a strict and comprehensive testing system for many years to ensure non-fragility of the specified glazing ” level of reassurance.

As I have briefly mentioned, it’s imperative to take into consideration not only the risks associated with temporary gaps during construction, but also the risks when access to the roof is needed later on in its life, for example, during maintenance or cleaning. If a contractor fails to pay attention to the complex area of the interface between the roof and the rooflight, which is the weakest point of the structure, then problems can arise.

It’s also vital to consider the

quality of the materials you are specifying. Some imported cheaper and lower quality materials may result in the longevity of the glazing being reduced, thus increasing overall costs and inconvenience to the end user. Also in some instances, a double skin is specified for glazing structures instead of a triple skin to cut costs. Not only does this not comply with Part L regulations, but can also reduce the strength and robustness of the structure, increasing the risks of danger to employees whilst working at height.

Rooflight manufacturers have a wealth of experience and information to hand, and what’s more, their advice is free. If you relay the project details in as much detail as possible, manufacturers can play a key role in helping you to achieve the best and safest solution for your particular project. Good manufacturers will provide free site assistance prior, during and postconstruction of any building project and with fragility is such a pressing issue, always ask whoever you purchase your products from if it is premium grade. m

Richard Lowe is technical services manager at Xtralite Rooflights. Since it was founded in 1993, Xtralite has sought to deliver the highest levels of professionalism, expertise and innovation to specifiers, installers and users of roof lights.

Pension package

Masterplan vision Atkins has won a contract as masterplanner to develop the IMX International Trade and Exhibition Centre, located within the new Hongqiao Central Business District (CBD) in Shanghai. The investment value for this project is approximately 4.8billion RMB. The contract will also see Atkins develop its iconic architectural designs for the IMX exhibition centre and supporting commercial development covering approximately 150,000 square metres. All buildings within the Atkins masterplan have been designed to meet or exceed China’s three-star Green Building Standard. As the highest Chinese standard for sustainability, this achievement demonstrates the country’s commitment to future proofing cities.

The IMX masterplan is a part of the prestigious Hongqiao CBD, which integrates businesses with the world class Hongqiao

Transportation Interchange. This large-scale integrated development is a Shanghai government-led initiative to directly connect Shanghai businesses with largescale transport hubs and is already considered a ‘pilot’ model for green CBD’s across China.

Steven Smit, Atkins’ architecture design director in Shanghai, said: “The opportunity to work with King Wai on this forward-looking project in a prestigious Shanghai location significantly benefits the Atkins portfolio. Our team has been able to interpret the client’s unique vision for their IMX brand with significant flair.

“With this development our client aims to enter the burgeoning e-commerce sector in China, which makes this project particularly exciting. The Atkins-designed interactive exhibition showroom serves as a platform to access a wide range of online goods. This innovative merchandise model will help drive our client’s business growth,” added Steven.

New research from workplace pensions provider NOW: Pensions reveals that while just one per cent of small and medium sized employers in the construction sector plan to contribute more than the legislative minimum when they enroll their employees into a workplace pension, nearly a quarter (23 per cent) intend to increase their contributions over time. In comparison, while three per cent of employers in the manufacturing sector expect to contribute more than the legislative minimum when they enroll their employees into a workplace pension, just 16 per cent intend to increase their contributions over time.

Morten Nilsson, CEO, NOW: Pensions said: “The perception is that large firms offer better pension provision than their SME counterparts but this isn’t necessarily true. Smaller companies very often know their employees personally and have a more paternalistic attitude.”

Nilsson continues: “Auto enrollment is a legal obligation but many companies in the construction sector are giving serious thought to the benefits of offering a more generous pension package.”

First for Europe Ben Adams Architects has announced that construction has started on Nobu’s first European Hotel, the Nobu Hotel Shoreditch in London. Expected to complete in early 2016, the 156room hotel will be located at 10-50 Willow Street in Shoreditch.

Trevor Horwell, chief executive officer of Nobu Hospitality added: “The Nobu Hotel Shoreditch in London is our first European hotel joining our growing portfolio collection of hotels covering select locations in the Americas, Middle East and Asia. Our proven business algorithm for hotel owners is our tactical and competitive advantage, focusing our effort on maximising return per square foot. We are as such continuing to expand our global hotel footprint with a robust development pipeline working with the best strategic partners.”

Asound barrier

to progress

Geoff Crowhurst considers how the issue of noise will impact on the public perception of major projects and how the latest acoustics technology will help ensure the success of these grand schemes

T

he construction industry continues to go from strength to strength, with a number of major construction projects and new developments underway around the UK. To ensure the success of these ambitious new construction projects, ranging from garden cities to high-speed rail links, it is of vital importance to mitigate newly created noise associated with them. This is not only inclusive of the initial planning application stage, but also applies to the delivery for the final end user and the impact it could have on existing local residents.

Key planning issue For all the enthusiasm generated by the Government and developers alike around marquee infrastructure projects, a key stumbling block at the initial planning application stage is the issue of noise and the impact it would have on the public. For example, this

10 Construction & Civil Engineering

has been a major criticism from local politicians and communities to the Government’s flagship infrastructure project, High Speed Rail 2 (HS2).

The Government has recognised that noise is an issue that has to be addressed when applications for construction projects are being considered by local authorities.

Indeed, in their Noise Action Plan, the Department for Environment, Food and Rural Affairs (Defra) identified that noise can have a detrimental effect on the quality of life, health and economic prosperity of those exposed to it, as well as on the natural environment. The National Planning Policy Framework, published March 2012, includes specific references to noise, making it a key consideration in the local decision-making procedure for planning applications. Noise impact assessments are now often required as part of this process, with developers keen to prove that a new building - be it a residential, business or

transportation development - will have minimal impact on local households’ surroundings.

Through innovative acoustic technology, noise consultants are now able to accurately predict the impact of noise from prospective developments on existing buildings surrounding any given construction site. This has been made possible through a 3D modelling process that precisely identifies the noise levels that buildings will be exposed to, whether from a new rail line or road. By using noise modelling techniques, noise consultants are able to treat buildings with the right noise mitigation solutions, minimising the impact of new developments on local residents.

Stumbling block Noise must also be a consideration during the construction phase of a development, with high profile projects around the country at risk of having to halt progress for weeks

An example of IAC’s 3D acoustic modelling for a current railway project in Paris, France. The different colours represent the level of exposure to noise emissions

at a time, due to excessive noise emissions. Developers are not only faced with delays, but also with large additional financial costs. This in turn leads to negative headlines and a resentful public perception in the local area, two things that are extremely undesirable for developers.

Building sustainability It is not just during the planning and consenting stage that developers need to consider noise emissions and their impact on local residents. Once fully functioning, both residential and commercial buildings are noisy places. For example, one of the most common causes of high noise emissions in new buildings is heating/ cooling ventilation and climate control systems. The noise from these huge systems creates challenges for the operation of such buildings because the noise is audible to the residents as well as the households in the immediate vicinity.

IAC Acoustics has been actively involved in a number of developments, such as the £70 million mixed-use Kingston Heights project developed

by United House, mitigating exactly this problem. Kingston Heights will provide 56 residential apartments, more than 81 privately owned apartments as well as a 142-bedroom hotel and conference centre.

The challenge of the project was that new apartments were to be created above and adjacent to an existing noisy transformer unit. The transformer was completely boxed in and integrated into the new apartment building.

Working across all company divisions, IAC Acoustics managed the acoustic requirements of the building.

The noise reduction measures it put in place included the installation of acoustic louvres at the base of the outer walls and acoustic doors as well as fitting several tons of silencers in all the chimneys on top of the roofs. This was necessary to provide cooling airflow to the transforming unit now located on the ground floor of the building. Through the innovative technology used on the Kingston Heights development, IAC was able to successfully mitigate the excessive noise, allowing the development and the surrounding area to remain a desirable place to live and work in; a key priority of the developers throughout the building’s construction.

While investment and grand vision should always be encouraged in the construction sector, more thought has to be given to noise and its impact on the success of a prospective constructive project. Noise is not something that can be taken lightly, and mitigation is essential at every stage of a construction project.

Although environmental noise is predominately the responsibility of local authorities, the Government needs to ensure that there is a proactive approach from the top to ensure that noise is taken seriously when approaching and delivering major infrastructure projects such as HS2. m

Taking

care

David Diggle & Katy Lightbody give a heritage perspective on health buildings

N

umerous traditional hospitals and healthcare buildings are statutorily listed as buildings of special architectural or historic interest. Many provide strong architectural evidence of changing attitudes to the treatment of the sick and have long been some of our most functional, and largest, buildings. Some were built with great panache using up-to-date architectural fashions but many also have distinctive and sometimes rare features.

Alteration is inevitable in such intensively used buildings, and listed buildings are particularly challenging

12 Construction & Civil Engineering

where they require regular change and alteration. However, if undertaken carefully and informed by specialist advice, historic buildings can continue to be fit for purpose for modern healthcare and be given a new lease of life to the benefit of the wider hospital estate and to local communities.

Consenting regime Proposed works or development to health heritage assets will give rise to the need for specific consents and/or additional considerations when making applications for planning permission. Listed building consent is required for any works that would affect the character

of the building as one of special architectural or historic interest. In effect, this means works that may not require planning permission may require listed building consent, and the need should be checked early in the process with the local planning authority.

It is important to note that it is a criminal offence to execute or cause to be executed any works to a listed building that would affect its character, unless they are authorised – i.e. listed building consent has been granted. A related complication can be that objects or structures attached to a listed building, or within its curtilage, are also treated as being

part of the listed building. Therefore works, for example, to demolish an outbuilding within the curtilage of a listed building will normally require listed building consent.

Caution needs to exercised in undertaking works to listed health buildings and should be based upon some knowledge of the nature and extent of listing and the building’s special interest or significance.

Heritage ‘setting’ and ‘assets’

development near listed buildings and structures. All heritage assets have a ‘setting’ and that the concept of ‘setting’ contributing to an asset’s significance is defined in the National Planning Policy Framework (NPPF). National planning policy is directed at preserving elements of setting that are important to a heritage asset.

Since 2010, government planning policies for the historic environment have used the collective term ‘heritage asset’ to comprise ‘any

those such as listed buildings, conservation areas, registered parks and gardens, they may also include those that may be identified as being locally important - for example locally listed buildings or buildings of local importance or merit.

It is therefore vital in promoting change to understand the significance of the heritage asset in question, whether it is a listed building or a locally listed building, or whether the hospital campus is situated within a conservation

The issue of ‘setting’ to heritage assets also often crops up and can cause problems if not identified and assessed at an early stage, especially when contemplating new

building, monument, site, place or landscape identified as having a degree of significance meriting consideration in planning policies’.

Whilst heritage assets comprise

out a framework for assessment.

Similarly, the concept that setting can contribute to significance is now well established and guidance assists for assessing this and the related impact of application proposals.

In our experience it is now recognised that carefully managed change, based upon an understanding of the significance of the health heritage assets involved, is both inevitable and necessary in securing their long-term conservation.

Specialist advice is necessary to guide you through.

Removal of red tape To streamline the existing consenting process the Enterprise and Regulatory Reform Act 2013 was introduced by government. It was borne out of the Penfold Review from 2011, aimed at establishing action the government could take to promote economic growth and enhance the competitiveness of the historic environment.

The following new heritage provisions were introduced on the 6th April 2014, aimed at reducing

14 Construction & Civil Engineering

legislative burdens: l Heritage Partnership Agreements (HPAs) – A HPA is a non-statutory agreement which sets out an understanding of the significance of the heritage asset or assets and in particular what is not of special interest in listed buildings. Once the agreement is in place, it can reduce the number of occasions when listed building consent is required and thereby save the owner and local authority time and money.

HPAs can also grant listed building consent for specified works, reduce the need for serial applications, and, are likely to best apply to specific building types or complexes, where predictable and repetitive works are commonly carried out. They could be particularly useful for hospital campuses, which comprise of a number of heritage assets. l Certificates of Lawfulness for Proposed Works (CLPWs) – CLPWs are intended to provide a simple and fast mechanism to give clarity to owners on when listed building consent is not required. m

David Diggle is a director and Katy Lightbody an associate director, heritage at planning consultancy Turley. Turley Planning and Turley Heritage have worked extensively with NHS Trusts and other healthcare providers in understanding the significance of their heritage assets. It has advised on the alteration and extension of statutory listed hospitals and other buildings in healthcare use. It has also advised on the change of use and adaptation of redundant healthcare buildings being considered for disposal.

F

or many large businesses operating in the construction industry today, much of their work relies on the operation of capital assets, such as excavators and haulers.

These types of heavy equipment contribute to the business’s ability to generate profit. It is therefore a major requirement that they remain in operation at all times because if a piece of heavy machinery or vehicle breaks down, the detrimental effect on the business is loss of work and, ultimately, income.

Preventing failure is the key to capital asset management and it is a top priority for businesses operating

capital assets today, alongside having a sufficient maintenance service in place. For the mobile technician tasked with carrying out this responsibility, their role is truly mission-critical and there are many barriers that need to be overcome and customer requirements that need to be met in order to achieve a timely and efficient outcome.

Requirements to providing a mission-critical service The significant costs related to capital asset downtime have led field service providers to adopt more of a preventative and predictive maintenance solution as opposed to previously offering

break/fix service structures. Such a solution utilises accurate real-time machine data to determine the condition of an asset and emits an alert when maintenance should be performed. The value of this solution lies in its ability to allow convenient scheduling of corrective maintenance and to prevent unexpected equipment failures.

According to Aberdeen Group, Best-in-Class performers (the top 20 per cent of organisations) are more than 2.5 times more likely than all others to group multiple preventative tasks for a technician while they are already on a customer site (1). This proactive service not only prevents more

assets from breaking down, it also shows the customer that they are important.

In the event of a capital asset requiring repair, the most common customer complaint is when a technician does not resolve the issue first time. This may be due to not having the right part or tools, not having the right skills or not enough time to complete the job. Achieving a ‘first-time’ fix is therefore a priority and more and more organisations are beginning to realise the value of intelligent scheduling – incorporating technician knowledge, parts availability, and capacity into their scheduling processes to ensure that the technician arriving on site is actually the person who can resolve the customer’s issue, first time.

More than half of Best-inClass organisations use service performance data to evaluate the effectiveness of scheduling criteria (2). Indeed, by leveraging Performance Management Analytics tools, easily digestible performance reports can be generated and customised to showcase the key metrics of a field operation. Field service managers can identify the most productive performers, determine which schedules and routes produce the best results and compare results from one vehicle or worker against the entire workforce. Performance analysis can also help with job assignments so managers can better match the skills of field technicians to specific service calls.

This increases the prospect of firsttime case resolution.

Essentially, in the event of a capital asset requiring maintenance or repair, a major requirement from the customer is to have high level contact with the technician and to know the precise time that they will be arriving on-site, so that they know exactly when to power down and prepare the asset for service.

Timeliness and communication is key and providing this will ensure

“Field service technology can help significantly in capital asset management and provides mobile technicians tasked with this role to manage it successfully, first time, every time ” that the customer receives the level of service needed to mitigate the time that the asset will need to be out of action and avoid any unnecessary costs.

The solution – how can technology help?

Field service technology can help significantly in capital asset management and provides mobile technicians tasked with this role to manage it successfully, first time, every time.

Field service technology provides real-time visibility into day-to-day field operations, which allows fleet operators and dispatchers to make intelligent scheduling decisions. Real-time location intelligence and trip management tools embedded in the system can optimise route planning, reduce unscheduled stops and allocate tasks to the technician best suited for a job.

Such capabilities allow mobile workers to respond to customer requests as quickly and as efficiently as possible and improve productivity by increasing the number of jobs completed per day. This is particularly beneficial for mobile technicians visiting construction sites because they are often tasked with additional jobs on arrival which they have not accounted for. Therefore being able to save time elsewhere can result in more time with a customer and reduced risk of

being late or missing upcoming appointments.

Ultimately, the support of technology can significantly improve the management of capital assets and for the technician, is essential for meeting customer requirements and delivering a mission-critical service.

In construction industries today, businesses cannot afford to have inoperable assets, so the support of a solution to help technicians maintain, fix and improve the longevity of a capital asset is of the utmost importance. m 1 & 2: Aberdeen Group: Secrets to optimize field service for better customer experiences, 2013.

Careful cladding

18 Construction & Civil Engineering

Phil Rigby discusses some of the key points to consider with rainscreen cladding, including thermal, acoustic and fire performance

W

ith ever increasing improvements demanded by the Building Regulations for the thermal efficiency of buildings, the need to specify effective insulation products within rainscreen cladding systems is of paramount importance.

Rainscreen cladding offers designers, specifiers and engineers a wealth of options in new build and renovation projects, bringing practical benefits and aesthetic advantages to small structures and high-rise buildings alike.

However, before one can think about the aesthetical finish, there are a number of high performance considerations to factor in to ensure the safety and comfort of those within the building; covering thermal, acoustic and most importantly fire resistance. The insulation layer is a fundamental component of any successful rainscreen cladding system, and as such, must meet and exceed the criteria stated above.

Typical applications for rainscreen cladding include town/ city centre apartments, schools, hotels, hospitals, as well as any project requiring acoustic and fire performance as part of the specification.

Approved Document B:2007 - Volume 2 - Buildings other than dwelling houses, states that any insulation product used

in the ventilated external wall construction, as well as the cavity barriers of any building of 18 metres or more (approximately seven storeys) should be of limited combustibility, as defined in Appendix A. Limited combustibility can be defined as either materials which are classified as non-combustible, of density 300kg/m3 or more which meet the requirements of BS 476 Part 11: 1982, and materials classified as Class A2-s3,d2 or higher in accordance with BS EN 13501-1 Fire classification of insulation products.

As an alternative to complying with the requirements detailed above, compliance can be shown by testing the rainscreen cladding system in accordance with the requirements of BR 135, as confirmed in the extract below: External wall construction 12.5: The external envelope of a building should not provide a medium for fire spread if it is likely to be a risk to health or safety. The use of combustible materials in the cladding system and extensive cavities may present such a risk in tall buildings.

Additionally, guidance on external walls can be sought from paragraphs 12.6 to 12.9 or meet the performance criteria given in the BRE Report: Fire performance of external thermal insulation for walls of multi storey buildings (BR 135) for cladding systems using full scale test data from BS84141:2002 or BS 8414-2:2005.

Zurich Insurance’s School and Academy Design document goes even further, stating that ‘as a guide, non-combustible insulation should be used e.g. rock/mineral wool fibre type, stone wool, slag wool or man made mineral wool/fibre.’

This is where mineral wool insulation comes into a league of its own. It has the highest reaction to fire rating – Euroclass A1 and is noncombustible, so can confidently be used in line with Zurich insurance project guidelines. Rigid foam boards on the other hand have a

“ The many benefits of rainscreen cladding systems, including quick, efficient installation and outstanding thermal, acoustic and fire performance ” classification of B-F. Indeed, mineral wool insulation delivers a number of advantages over rigid foam boards in this type of application. For specifiers and installers, perhaps the most significant benefit is that mineral wool products are designed to friction fit between the cladding rails, so there is no cutting or taping to seal gaps. This can speed up the installation process making it ideal for fast track construction projects.

Plus, with no gaps between the insulation, there is no loss of thermal performance and no additional transfer of noise through the structure, making it a straightforward and effective solution. Indeed, mineral wool delivers excellent acoustic performance so it is ideal for minimising sound disturbance in large buildings or from the external environment – both key priorities within many rainscreen cladding systems.

Perhaps the most important consideration though when choosing insulation for a rainscreen cladding system, is the methodology used by the manufacturer to calculate the U-value. Some generate figures using standard elemental U-value calculation software based on the methodologies details in BS EN ISO 6946. However, in order to establish an accurate figure, the correction value for the brackets must be established by numerical modelling – and this is not always the case.

Manufacturers that can provide 3D numerically modelled U-value calculations in line with BS EN ISO 10211, will be able to guarantee the thermal performance of the rainscreen cladding system is accurately calculated. For thermal calculations that have not been

calculated in this way, a default correction of 0.30 W/m2K needs to be added to the calculated U-value.

It’s therefore always worth asking how the U-value calculations have been generated to ensure the figures provide an accurate reflection of the product’s real performance. Knauf Insulation’s 3D modelling calculations are provided by its Technical Advice and Support Centre (TASC) and the team there is always available to answer any questions specifiers and installers may have.

The many benefits of rainscreen cladding systems, including quick, efficient installation and outstanding thermal, acoustic and fire performance, mean they are likely to continue growing in popularity. To ensure they offer the best long-term value, choosing the right insulation is absolutely critical specifiers should not be afraid to approach manufactures for advice and assistance in achieving the correct specification for their project. m

Phil Rigby is product manager – rock mineral wool at Knauf Insulation. Knauf Insulation is the UK’s leading manufacturer of insulation products, and the only producer of four types of insulation: Earthwool, encompassing glass and rock mineral wool with the revolutionary ECOSE Technology, extruded polystyrene (XPS) under the Polyfoam brand name and extruded polyethylene (XPE). It is one of the most respected names in insulation worldwide, offering a broad range of insulation solutions to meet the increasing demand for energy efficiency, fire resistance and acoustic performance in new and existing homes, nonresidential buildings and industrial applications.

A

ll of the construction and specialpurpose machines manufactured

by Menzi Muck have the same intention at their core –the driver/ operator should feel ‘like a king’.

The company’s successful record proves that this approach is not without merit, and it has achieved the position of global market and technology leader, with its products gaining a formidable reputation and an ever-increasing number of loyal customers the world over.

The creation of today’s Menzi Muck walking excavator/spider excavator can be credited to company founder Ernst Menzi (1897-1984) who was not just an ingenious inventor, but also a born entrepreneur. He founded his first company at the age of just 26, and the history of the Menzi Muck walking excavator would not be the same without him. His spirit of invention and innovation lives on, and the business’ walking excavators and mobile all-purpose excavators are still developed with attention to detail and through close co-operation with customers.

What makes a spider excavator unique is that because of its flexible chassis it has the ability to fulfil the requirements of many applications – so for example it can work on gradients of up to 100 per cent, in

water up to 2.5 m deep or in deep mud, on mountains or on the ocean bed: the Menzi Muck can adapt to any type of ground. A high degree of motorisation and unique stability result in performance rates up to 70 per cent higher than those of conventional machines in the same weight class.

In addition, Menzi Muck aims to recognise customer requirements at an early stage of product development and directs its

attention to meeting and even exceeding these. One of its major strengths as a business is its ability to turn customers’ ideas into reality.

This gives rise to individual and tailor-made solutions, which can be put to profitable use in niche markets. Its partners are successful customers who are committed to an open and collaborative acquisition policy and are faithful to their obligations. Menzi Muck offers a full end-to-end service,

Construction & Civil Engineering 21

PROFILE: MENZI MUCK

with a focus on each area of sales, development, installation and service.

The Menzi Muck mobile spider excavator comes in three different basic versions, in weight classes from seven to 10.5 tons. The newest additions to the range are the M3 and M5 series diggers, which are both versatile and economical. The M3 mobile spider excavator has been designed to meet every need of the customer. With numerous options, the machine can be bespoke designed to meet specific client needs and every detail is based on functionality, safety and comfort. The result is a powerful, spider machine that is setting new standards in the eight-ton class.

One of the major innovations appearing on the M3 is the Menzi Powerboom – a unique boom of the M Series. This is mounted

22 Construction & Civil Engineering

horizontally in the centre part and therefore collisions at the boom cylinder are impossible. The new kinematics of Menzi Muck are also opening up new dimensions: optimum work in the close-up range at the minimum possible swivel radius is contrasted with maximum stretching of the boom.

The Menzi power booster thereby supplies the highest possible forces over the whole working range.

Operator comfort and safety are of course also prioritised, with a panoramic cockpit, extensive standard equipment and dashboard with LCD display all included. From the ergonomic joystick with proportional rocker and hand support to the airsuspended operator’s seat with

adjustable armrests and foot pedals, no stone has been left unturned to provide the driver with a maximum level of comfort.

A more powerful option, the Menzi Muck M5, is strong, fast and comfortable. It has been designed with a focus on power, mobility and maximum output, as well as being supremely equipped. However, as mentioned previously, it is the driver that ranks above all else, even technical sophistication. Every detail in the driver’s cab is based on functionality, safety and comfort, with the panoramic cockpit only being a part of it. The machine also features clever technology such as the Anticipating Power Management system that brings up to 30 per cent fuel savings,

and a Sensitive Load Sensing hydraulic system that is geared towards smooth and optimised performance.

These new models fit in alongside the existing A40, A20 and Menzi Dumper 45rd – all of which feature innovative technology and boast a range of features. The wheeled dumper Menzi 45rd, for example, is the first and only to have an engine that already meets the exhaust emission level 3b. This is achieved through an exhaust gas treatment system, which eliminates dangerous soot particles, and is already integrated in the modern turbo-diesel engine.

njoying international success since its inception in 1869, family firm Ammann has spent the last 135 years developing its product portfolio, supply network and services through strategic acquisition to become a leading global supplier of asphalt mixing plants, compaction machines and services for the construction industry. Conducting business in the building industry through Ammann Construction Equipment and Avesco AG, the group has utilised its entrepreneurial spirit to establish itself in new and emerging markets with sales, services and local production in areas such as North America, Latin America, India, Southern Africa and South East Asia.

Elaborating further on the group’s history managing director of Ammann Verdichtung GmbH Bernd Holz begins: “Ammann was founded 130 years ago and has acquired a number of companies throughout this time; the entity I manage was added to Ammann’s group of companies in 1984 and was previously known as Duomat GmbH. It also acquired Alfelder Iron Works in Germany in 1984, before acquiring Societa Italiana Macchine SIM, in Bussolengo, Italy, in 1991.

More recently the group acquired Stavostroj in Nove Mesto, Czech

Republic, in 2005, and started paver and trench roller production in Langenthal in 2010. Aiming to further develop its presence in strong markets, Ammann founded Ammann South Africa, Ammann Brazil, Ammann Bulgaria and Ammann Singapore in 2012 and opened a manufacturing facility in Gravatai, Brazil, and founded a joint venture with Ammann Apollo India in Ahmedabad in 2013.”

He continues: “The division I operate in Germany is a small part of Ammann, operating as a production facility for light compaction equipment such as small rammers, weighing between 60 to 80 kilos, vibrating plates,

which can only move forward, and reversible plates, that can move both forwards and backwards.

We also produce very heavy, fully hydraulic driven plates, which have a maximum weight of 850 kilos.” Powerful, economic, operator-friendly and ergonomic in design, Ammann rammers are the ideal compaction machine for construction projects involving trench construction, backfilling and sub-layer compaction for basements and industrial buildings as well as road and pathway repair.

All rammers provide fatigue-free operation through an elastically supported guide and a sure-grip, vibration-insulated guide handle.

Meanwhile, the group’s vibratory plate product portfolio includes a broad range of equipment, from remote-controlled vibratory plates, which provides operator safety and a powerful performance through its diesel engine, to forward moving vibratory plates, which are hydraulically powered and user friendly to ensure high machine performance. However, it is the group’s fully hydraulic attachment systems that Bernd anticipates increased demand for over the coming years. “Within our product portfolio we have attachments that can mount on an excavator, such as vibrating plate attachments,

and we are seeing that these fully hydraulic attachment systems can increase efficiency on job sites by eradicating the need to jump out of the excavator and attach manually by hand. Tools can be changed quickly and the system is easily adaptable on all excavators from two tonnes to 30 tonnes. We are not unique in this market but we are the best and we anticipate increased demand for this technology once it becomes better known in the market,” he highlights.

Approximately 40-45 per cent of annual production at the facility is sent to the German market, with the rest being delivered to international markets such as France, Poland, Switzerland and Austria. “We produced approximately 15,000 units last year for our core customer base in Europe,” says Bernd. “We also sell overseas to Latin America for countries like Brazil, but these are emerging markets for Ammann; we began operating there two years ago, so it is a growing market, step by step.”

Boasting the claim: ‘Productivity partnership for a lifetime’ Ammann retains core values of independence, sustainability and credibility through maintaining a sustainable service network and

Construction & Civil Engineering 29

delivering credible commitment to its customers around the world.

With factories in Germany, Czech Republic, Switzerland, Italy, India, China and Brazil, the group ensures its expert personnel are in close proximity to its customers and relevant markets 24 hours a day; it also has more than 60,000 spare and replacement parts in stock, with a spare parts service available at any hour of the day. Customer service and product reliability are critical keys to the group’s success and it is proud of the ongoing close relationships it has developed with clients through understanding their demands and striving to meet them every day, as Bernd highlights: “The reliability of our products is a major strength of the group, which is known for quality and lifetime cost effectiveness. Our slogan means we sell these products mainly through our distributors and dealers, with whom we have a long-term relationship alongside our end users; we work together, we are like a family. We are also committed to long-term results and don’t jump in and out of markets to gain over the short-term.”

Indeed, this commitment to longterm results led to Bernd finding opportunities for improvement within the production facility when he joined Ammann seven years ago; viewed as his biggest achievement so far while operating under the Ammann umbrella, Bernd introduced a lean manufacturing system that heightened efficiency and ensured the facility could reach targets during busy periods.

“When I began working here in 2007 it was a booming year for road construction equipment, so we focused on issues on the production side of operations and recognised that we were unable to produce enough units a week or month that our sales required. We also noticed that lead times were too long and that a lot of material was involved in the process so there was a lot of carrying material three or four times before it was

assembled on the assembly line.

This way of working was inefficient so we began a complete analysis alongside a third party consultant and also trained our personnel to understand the meaning of lean production.”

Using the medium sized vibrating plate product line for a test run, the facility set up new shelves with production tools and materials in close proximity to personnel; this simple improvement massively boosted efficiency through eliminating the need for staff to rush back and forth to get the item they required. “In addition we reduced long lead times in the facility through ensuring there is someone who will come and refill empty material boxes. These improvements led to reducing our inventory level of unfinished goods by 35 per cent and improving lead time production by 20 per cent; we now produce more machines with the same people on board as before.”

Keen to understand the needs of its major client base, the group regularly develops its products through innovative collaborations with experts to optimise product lines and also offer advantages to clients by listening to their issues.

“After summer 2014 we will launch a new fully hydraulic driven plate, which will weigh in at 850 kilos and will have a water cooled three cylinder diesel engine,” enthuses Bernd. “This is a new development for us, having previously use one

cylinder Hatz diesel engines, so this product is much more powerful and will in fact be the most powerful vibrating plate on the market. A lot of customers will use this big plate because it is cost effective and, judging from our calculations, far more efficient than a seven tonne compactor. The marketing campaign for this will begin in July 2014 and production will begin a few months later once testing has been completed.”

Renowned around the globe for its high quality products, the group has recently enhanced its presence with a major marketing campaign under the title ‘My Ammann’, which involves satisfied end users standing next to their product, as Bernd highlights: “Starting in 2013 the ‘My Ammann’ campaign came from our headquarters in Switzerland and involves one of our many customers standing next to a machine from our product range and saying they are proud of ‘My Ammann’; we are very proud of this campaign and have noticed that one of our competitors is now doing a similar campaign for their own products.”

Having set the foundations for ongoing growth around the globe, the future looks positive for Ammann as it focuses on further developing its impressive product range and becomes increasingly more competitive in a growing market. “After 2014 we will be completing a new range of small forward moving vibrating plates; in addition we will be focusing on being competitive in overseas countries by developing new products that can be produced not only in Germany, but in our facilities in India or China,” concludes Bernd. m

Providing consultation, design, supply and erection services to the construction industry, KLH UK is tackling the market head on, and changing opinions on the use of timber in construction along the way The business additionally undertakes associated work such as glulam beams & columns and associated structural steelwork.

Operating globally, the group has sales partners throughout Europe, Japan, Turkey, Australia and North America. KLH UK is the only part of the group offering a full design, supply and installation package.

“The market throughout the recession has focused mainly on the commercial drivers, with perhaps less focus on sustainability. However, sustainability sits nicely alongside commercial as CLT offers added value to our clients by examples such as the reduction in the need for PV by providing a fabric first approach to carbon reductions or the inherent air tightness of the structure from precision cutting of panels and openings providing a more efficient building in terms of operational carbon use. Although the market has been commercially driven, we are still able to compete on the basis of the overall

programme advantages that we can bring by using CLT,” explains Nic Clark, managing director. Until now, the company’s market has been very much focused on education, but there is a growing requirement for multi-occupancy residential, student accommodation and hotels, alongside the educational builds.

“The market is definitely improving with new enquiries surrounding residential projects coming through,” he adds.

KLH UK has worked on a number of impressive projects such as the UK’s tallest timber tower: Murray Grove, and the UK’s largest CLT structure: William Perkins Academy in Greenford, where 23,000 sq metres of timber was used in the construction. The company was also involved in the formatting of the design and supply for the world’s tallest tower in Melbourne, Australia, and recently completed Kingsgate House which was the world’s first major construction project to achieve PEFC Project Certification.

“We have a team of engineers focused on providing scheme designs, temporary works design, and full designs and connection drawings for our projects. A large aspect of their work is converting existing tender designs or architectural concepts into a CLT design, taking into account the

loading, spans, the fire requirements and vibration frequency requirements,” explains Nic. The next stage is the production of a 3D model detailing the design.

Once agreed with the customer, a full detailed design is produced, including the connection design. A team of technicians then produces a model that the factory can work to, manufacturing and cutting the individual panels. Information detailing all the cuts for the windows and doors, the chases for the electrical installations is inputted into the CNC machines at the factory in Austria.

The panel is produced in a standard size with the individual wall, floor & roof elements cut out and loaded for delivery in an order that suits the sequence of erection on site. “We use subcontract teams of improved installers for the site installation. However we do see a skills shortage in timber engineering and as a measure to tackle this we have sponsored a post-graduate at Napier to do a Masters degree in timber engineering for the 2014/2015 term, as well as having a home-grown approach to training.”

“Timber engineers are rare in the market so we recruit engineers

and provide on-the-job training in the Euro-code and timber design,” says Nic. Discussing training and attracting the right candidates into the industry he adds: “We need to look at the skills shortage that exists and as an industry we need to begin developing that. We are working closely with the University of Bath to generate interest in timber engineering but it really requires a drive on a more macro level. Young talent needs to see that there is a future in building in timber, and we need to generate some impressive structures to gain their interest.

Some Government intervention into research & training would lead the way to more sustainable construction taking place in the UK.” With the material supply chain fully in-house its clients are given the confidence in the process, offering a collaborative

approach based on skills and expertise throughout the process.

As a straightforward thinking business, it understands that the technology and process is new and it is important to be clear with the customer about the process and its

design throughout all stages of the project.

“Bringing a new technology to the market has brought with it many challenges. People are happy with what they know and are very reluctant to try anything new, but it is a hurdle that we have worked on overcoming and we can almost see the finishing line.

There is a large proportion of the design community that is very interested in sustainability so that is where some of the momentum is and that has been fantastic. We know many contractors have a sustainability agenda but every so often we are confronted with negative views, but it is interesting to see their reaction at the finished article; they almost always impressed, if not converted,” explains Nic. There are still some hurdles

to overcome and KLH UK has recently invested money into testing and research into fire during the construction phase with the involvement of the HSE. “We are also meeting some resistance from the insurance market, specifically

around the hotel sector where they are concerned about insuring the larger hotel schemes, which is odd given they insure CLT hotels on the continent ” Nic points out.

However one factor that is clearly a challenge amongst subcontractors

such as KLH UK is the struggle it faces in the payments terms with main contractors, typically waiting in excess of two months from manufacture before receiving payment.

“The future looks positive, there is massive opportunity which comes from the shortage of housing in the southeast and London, and as the benefit of CLT becomes more recognised contractors are looking to use this model. The design works really well, it is quick and provides very good value for money. We are always investing in the development of the product, currently looking at hybrid offers so that we can supply to different sectors such as the retail or the commercial sectors, where typically the open plan spans required are beyond the economical reach of the CLT. The vision for CLT as a product is that it becomes fully recognised as a mainstream construction material, alongside concrete and steel work. We want the product to be considered as a first choice, not simply an alternative,” Nic concludes. m

With a history dating back to 1946, Selwood Ltd has a proud history of delivering high-quality pump and plant equipment within both the direct sales and hire markets

ince emerging in postwar Britain during a time of enormous rebuilding and development, Selwood has endured as a leading name within the manufacturing and plant hire sector and is considered to be only the second plant hire business established within the UK. As such the company can rightfully claim to have entered the market at ‘ground level’ and has since diversified to match the trends and demands of an ever-evolving marketplace.

sales and manufacturing division for example, produces pumps and sells them within the UK and to the wider export market. Although Selwood enjoys a strong presence within the UK around 75 per cent of the pumps that the company produces are exported globally via its worldwide distribution network.

“We exported to in excess of 50 countries around the world last year,” managing director Chris Garrett elaborates. “The traditional bases are with major European markets but equally Australia, New Zealand and South Africa.

A key market for us is the oil industry where Selwood products are applied to the environmental protection side of the industry specifically. We can deliver our pumps to anywhere they are required.”

Furthermore Selwood has developed long-standing relationships with clients at home and abroad during its long history, which in turn have established the Selwood name as a highly trusted brand and a mark of quality as Chris further explains: “We have two relationships that date back to the 1960s and 1970s in South Africa and the Netherlands, so in this respect Selwood products have been around the world for many years and therefore clients know the product. We also take part in exhibitions around the world to demonstrate Selwood products as well.”

The range of pumps supplied by Selwood includes solids handing pumps, drainer pumps, high-head pumps, positive displacement pumps, hydraulic submersible

Selwood is currently headquartered in Eastleigh, Hampshire and today enjoys a yearly turnover of around £50 million and has expanded to include eight locations dedicated to plant-hire and a further 20 locations dealing with pump hire in addition to its manufacturing facility, which employ around 420 personnel across the business.

Today the business is organised into three separate divisions that offer targeted services to the company’s chosen sectors within the UK and abroad. The pump

pumps and super silent pumps as well as a full range of accessories and the patented Selprime selfpriming system, which encompasses an environmentally friendly design that has none of the associated drawbacks of oil vapour emissions and oil emulsification that can be associated with other designs. All pumps are produced in association with trusted contractors within the UK and Selwood constantly works to ensure that its standards remain high and that its designs remain innovative and market leading. The company’s hire operations focus on the UK market where it has established itself as the leading provider of pumps, plant hire equipment and accessories. “We assemble the pumps on site, they are all cast in UK foundries and machined within the UK before they come to us to be put together. We obviously own all the patterns and associated tooling, so we operate more of an onsite assembly facility with all work sourced in the UK. We also have an engineering section that makes modifications to existing products for bespoke options and development. The most recent changes to be undertaken are on tier changes to engines where we are moving to tier four, which has meant a lot of design work to package the new engines onto the product. Equally we have just launched a new range where we have revisited our H range of high head pumps and that was during 2013 and there are a few new products in this range that are still in the pipeline.”

The H range of pumps currently encompasses the H80, H100, H125 and H200 and includes capacities of between 95 m3/hr (H80) to 950 m3/hr (H200); the H design also includes mechanical shaft sealing that provides leak-free operation.

The most recently launched model is the H200, however general manager Tony Killick believes that the H150 offering a maximum capacity of 450m3/hr including solids of up to 38mm – will possibly be the H

range’s strongest selling variant.

“We have segregated our rental business in the UK so that it is specialised. We have specialist plant and pump hire facilities so that the two do not become confused. The company’s personnel come to work and have one thing to focus on, we are not trying to run mixed locations and drive cost synergies out of the business. What we are focused on is giving the customer exactly what they need and that is a key strategy of the business.”

Although the global recession spurred a slowdown in construction projects within the UK and around the world, Selwood has remained strong and used the experience of weathering the economic downturn to increase the efficiency

the UK market in the quarrying sector and we are shipping a lot of these [H150] to Australasia, including Indonesia and Australia.

Canada has also had some of the H150 body units.”

The Selwood pump hire division and plant sales division and hire fleet are both focused on the UK marketplace, operating nationally as trusted partners in various applications. Selwood pumps can tackle clean water, water with fine and larger solids, sludge, slurries, oils and hydrocarbons screened and crude sewage, while the company’s plant equipment has applications within construction, earth handling and civil engineering. Although Selwood offers its clients a diverse range of products, its main focus is on providing first-class service and addressing the needs of its customers as Chris further explains:

of the business and ensure that it is well placed to meet the needs of a resurgent market. “We see a continued recovery in the UK construction industry and we are looking at that positively,” Chris concludes. “We have supply frameworks with eight out of 11 of the UK’s water and sewage companies and that is obviously a key part of our market, however we have also established a team who are focused on developing work away from the water industry. There are of course, huge opportunities overseas be that directly or through distributors. I think that over the next three to five years the plan is to stay true to the company’s missions and values. Obviously we focus on sales and numbers for the longevity of the business but I think service is what really drives our business forward.” m
