MAJOR PROJECT

Leadenhall Laing O’Rourke’s Design for Manufacture and Assembly (DfMA) approach has revolutionised the way London’s new ‘Cheesegrater’ building has been constructed. By Steve Cork

ith its unique sloping silhouette and towering 224m height, the Leadenhall Building, in London’s Square Mile, has made an undeniable impact on the city’s skyline, earning the ‘Cheesegrater’ nickname long before the project has been completed.

An understated, yet modern

design, it has caught the eye of tourists and Londoners alike among a raft of modern, high profile skyscrapers. Much of this can be attributed to the partnership between construction and engineering specialists Laing O’Rourke and renowned architects Rogers Stirk Harbour + Partners (RSH+P), who chosen by the Leadenhall Development Company,

a joint venture between British Land and Oxford Properties, have brought this visionary building to life.

Already an iconic modern landmark, the Leadenhall Building’s eye-catching shape was conceived

by Graham Stirk of RSH+P to preserve the view of St Paul’s Cathedral from the historic pub Ye Olde Cheshire Cheese in Fleet

Street. To do this, he designed the building elevation to slope away from the view of St Christopher Wren’s 111m high famous domed cathedral, whilst still providing the space required for the intended offices restaurant and ground floor public space.

The diagonal slant of the Leadenhall Building meant that a traditional central concrete core

could not be used, with RSH+P instead designing an innovative steel structure to maintain the shape whilst providing the structural support the skyscraper requires. The use of a steel structure created a number of challenges for both the design and construction teams, most importantly the need to offset the natural tendency of the structure to lean north.

To overcome this, active alignment was used, which saw a shortening of the diagonal beams to pull the building south, ensuring it maintained its shape within fine tolerances. To fix these beams in to place, nearly 30,000 megabolts (ranging from 48mm to up to 76mm) were used, each of which were mechanically stretched before installation to allow them to shrink back to their original

size and essentially ‘squash’ the beams together – making for a very secure and rigid structure.

With 41 floors of office space, an open public gallery on the ground floor (rising seven storeys high), plans for a restaurant on the third floor and two reception areas, Laing O’Rourke needed to apply careful planning and a meticulous approach to the project. The use of the company’s leading Design for Manufacture and Assembly

4 Construction & Civil Engineering

(DfMA) approach on the project revolutionised the way in which the building was constructed, with 85 per cent of it being manufactured off site before being transported to the building’s central London location for assembly.

With the footprint of the building taking up most of the site, the mega columns could not be stored easily so were installed almost immediately upon delivery using one of four 250 tonne cranes. The

longest of the columns, measuring 28m in length and 60 tonnes in weight, are the largest items that can be brought in to the City and were delivered to site with a police escort during the hours of 1am and 5am. Work continued 24/7 to ensure the columns were safely in place and to reduce the amount of disruption caused. In total, the building now contains 18,000 tonnes of steel, a majority of which can still be seen from the outside of the building and frame the glass windows that provide the stunning views of London.

Without the use of a central concrete core, Laing O’Rourke needed to find a solution to form the structure and floors of the building internally – and again utilised DfMA. From detailed plans, the company created 138 table shaped components offsite, each weighing 35 tonnes, which could be craned in to place within two hours

and came complete with services and structural flooring already installed.

For the main flooring, Laing O’Rourke used its E6 flooring solution, allowing the solid precast concrete components to be manufactured offsite before being delivered for installation. Over the course of the project, Laing O’Rourke’s Explore Industrial Park (EIP) produced 7191 precast floor planks, which covered 65,000m² of floor plate area and significantly reduced the amount of time required for installing this part of the building. Typically it would take twice as long using the traditional in-situ wet concrete method.

Speed, however, isn’t the only benefit of off-site manufacturing on such a project. It makes for a safer construction site by producing components in a controlled factory environment rather than trying to build at height, exposed to the

changing weather. The automated manufacturing process also enables a more cost effective approach, calculating materials with absolute precision, and eliminating waste from the outset while the enhanced thermal efficiency in buildings and life cycle costs are reduced due to the superior performance of components needing less maintenance.

Elsewhere, The Leadenhall Building contains a total of 20 passenger lifts, which are some of the fastest panoramic elevators in Europe, taking just 25 seconds from ground floor to the 45th floor – a total of eight metres per second. Aligning the building correctly was essential to ensure these lifts ran smoothly and had the required support to operate, with each lift requiring a tolerance of +/- 25mm. In addition to the passenger lifts, the building also contains two service lifts, two fire-fighting lifts, two bespoke vehicle lifts that provide basement access

and two scenic lifts that service the ground to third floor.

At the very top of the building, the attic contains the plant, which includes switch rooms, four 20tonne generators, boilers, a pump skid (used for heating) and four cooling towers as well as a number of additional items to maintain the huge building. Extensive 3D digital modelling was used to design and position this area, with a full time inhouse specialist employed on site for five months to map out and oversee the installation. The complexity of the steel framework meant that a mixture of cranes and trolleys were used to install each of the items into the attic, which totalled almost 410 tonnes.

The Leadenhall Building is now approaching practical completion, when it will be handed over to the Leadenhall Development Company for fit out ahead of its opening in 2015. m

CASE STUDY

lobally, little attention is paid to gaseous emissions from wastewater treatment processes.

This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions

6 Construction & Civil Engineering

of greenhouse gases (GHGs) to help in the city’s efforts to combat climate change and also to help improve the wastewater treatment process.

Employing a multigas FTIR (Fourier Transform InfraRed) analyser from Gasmet, a Helsinkibased manufacturer of analytical instrumentation, the plant’s managers are able to measure the effects of process control on GHG emissions such as carbon dioxide,

methane and nitrous oxide. This also provides an insight into the fate of nitrogenous compounds within the wastewater stream.

Background The Viikinmäki wastewater treatment plant was built in 1994 to process wastewater from both domestic (85 per cent) and industrial (15 per cent) sources. However, the average temperature in Helsinki

Conducting

tests

Viikinmäki is the only plant in the world monitoring the GHG emissions of wastewater treatment, and the data is of major significance

between December and February is around minus four oC, with extremes below minus 20 and even minus 30 oC, so the plant was built almost entirely underground to avoid the freezing temperatures. Underground construction is common practice in the Nordic countries, providing other advantages such as land availability above the plant and the provision of stable conditions for process control and odour management.

The Viikinmäki plant is the largest wastewater treatment facility in Finland, handling approximately 270,000 m³ of wastewater per day, which amounts to about 100 million m³ per year. The wastewater is treated in compliance with the Finnish Wastewater Discharge Permit, which is stricter than the EU Water Framework Directive for parameters such as nitrogen removal, phosphate

content, BOD, COD and suspended solids. Following treatment, the purified / treated wastewater is conveyed eight km out to sea and to a depth of over 20m. This might seem superfluous, but the 16 km long discharge pipe was built in the 1980s and was designed to ensure that discharged wastewater did not accumulate on the shallow and scattered shore and nature reserves along the coastline of Helsinki.

The treatment process is based on the activated sludge method and includes three phases: mechanical, biological and chemical treatment.

Traditional nitrogen removal has been enhanced with a biological filter that utilises denitrification bacteria.

The organic matter contained in the sludge produced in the wastewater treatment process is exploited by digesting the sludge, and the biogas generated in the digestion process is collected for further use. Thanks to the energy produced from biogas, the treatment plant is self-sufficient in terms of heating and about 70 per cent self-sufficient in terms

Construction & Civil Engineering 7

CASE STUDY

of electricity. However, the plant aims to be fully energy self-sufficient in the near future, and around 60,000 tonnes of dried waste sludge is sold each year for landscaping purposes.

Gas monitoring As a result of the size of the plant (E-PRTR reporting) and the commitment of the Helsinki Region Environmental Services Authority (HSY) to the protection of the environment, it was necessary to monitor or to model gaseous emissions. At the beginning of the E-PRTR reporting requirements (2007) HSY modelled the annual gaseous emissions based on grab samples. However, monitoring was relatively simple to implement because the plant is enclosed underground and a gas exhaust system was already in place.

Initially, a portable FTIR analyzer from Gasmet was hired for a short period to assess the plant’s emissions and for research purposes. However, as Mari Heinonen, process manager at Viikinmäki, reports: “The gas emissions data were very interesting but they were not representative of the annual emissions, and posed more questions than they answered.

“We therefore purchased a continuous emissions monitoring system (CEMS) from Gasmet, which was installed in late 2012 and we now have our first full year’s data for 2013.

“Very little data has been published on the GHG emissions of wastewater treatment and as far as we are aware, Viikinmäki is the only plant in the world conducting this type of monitoring, so our data is likely to be of major significance.”

The Gasmet CEMS employs an FTIR spectrometer to obtain infrared spectra from the waste gas stream by first collecting an ‘interferogram’ of the sample signal with an interferometer, which measures all infrared frequencies simultaneously to produce a spectrum from which qualitative and quantitative data are produced. For example, the CEMS at Viikinmäki continuously displays

8 Construction & Civil Engineering

“Gasmet FTIR

technology was chosen for the Viikinmäki plant because of its ability to monitor multiple gases simultaneously ” emissions data for CH4, N2O, CO2, NO, NO2, and NH3.

Over a number of years, Gasmet has established a library of FTIR reference spectra that now extends to simultaneous quantification of 50 gases or identification of unknowns from a collection of 5000+ gases.

This means that it is possible to reanalyse produced spectra with the instrument’s PC based software (Calcmet) and thereby to identify unknown gases – a major advantage of FTIR. Whilst FTIR is able to analyse an enormous number of gases, the technique is not suitable for noble gases, homonuclear diatomic gases (e.g., N2, Cl2, H2, F2, etc) or H2S (detection limit too high).

Gasmet FTIR technology was chosen for the Viikinmäki plant because of its ability to monitor multiple gases simultaneously.

However Mari says: “The system has performed very well, with very little maintenance required. Zero point calibration with nitrogen (background) just takes a few minutes each day and is fully automated. Water vapour calibration is conducted at least once per year, but under normal circumstances no other calibration is necessary.”

With the benefit of the monitoring data, Mari Heinonen has calculated the annual emissions for methane

to be around 350 tonnes, and for nitrous oxide around 134 tonnes.

This means that the emissions per cubic meter of wastewater equate to 3.5g of methane and 1.34g of nitrous oxide.

Looking forward, Mari believes that it will be possible to use the gas monitoring data to improve process control: “Traditional monitoring/control systems focus on concentrations of oxygen, nitrate and ammonia in the water, but if we detect high levels of N2O gas for example, this may indicate a problem in the process that we can use as a feedback control.

“The monitoring data for gaseous nitrogen compounds (N2O, NH3, NOx) complements water analysis and provides a more complete picture of the nitrogen cycle in the treatment process.

“Clearly, further research will be required, but this work may indicate a need to consider the fate of nitrogenous compounds beyond just those in the wastewater; the removal of nitrogen from wastewater is a key objective, but if this results in high N2O emissions the process may need to be managed in a different way.” m

Expanded range Purposely built for waste handling, the new Cat G315B WH Waste Handling Grapple is designed for hydraulic excavators with operating weights ranging from 15 to 22 metric tons. The new grapple is an addition to the Cat G300 Series and is engineered to handle large volumes of low-density material, such as plastic and foam products.

“The addition of the G315 WH grapple expands our current worktool offering to the growing number of businesses in waste handling and recycling,” says Dick Hermann, commercial manager, Caterpillar Work Tools B.V. To ensure enhanced customer value, the new G315 WH grapple is designed with a large, 800-litre-capacity shell to minimise the number of loading passes and subsequently to reduce the carrier’s fuel consumption - yielding a high return on investment for wastehandling and recycling companies.

The G315 WH grapple features a top plate for mounting an adapter bracket, which allows the grapple to be exchanged among multiple carriers. When used with the dedicated Cat CW Quick Coupler, the grapple can be exchanged in seconds for other Cat work tools. Cat excavators have pre-programmed hydraulic settings to accommodate G300 Series grapples.

One to watch Kea (also known as Tzia) is part of Greece’s archipelago of Cyclades islands, but is more remote than the better-known tourist hotspots of Mykonos and Santorini. However, following the lead of savvy Athenians (locals always know best), this 132 sq km bolthole has recently started attracting foreigners looking to buy summerhouses with a difference.

The recent increase in demand for holiday homes on the island justifies the work of renowned architect and developer Christos Vlachos, who has built more than 100 tailor-made holiday houses in Kea and has become famous for his futuristic glass structures, allowing breath-taking sea views from every room. Furthermore, he recently contributed to the creation of new legislation regarding ‘cave houses’, which are houses carved into the land, thus minimising human influence on the landscape while retaining panoramic sea views. Although Vlachos develops properties in many islands of the Cyclades, Kea remains the destination of choice for his ‘high quality holiday houses’ (www.kea-estate.gr).

Developer Ioannis Michalopoulos is also hard at work, in collaboration with cofounder and architect Thanassis Kyratsous, creating traditional-style buildings that are sensitive to the environment and employ native materials. The firm’s luxurious, rustic yet contemporary homes are represented by his company Blue Mountain (bluemountain.gr), and are built to the highest standards and specifications.

Housing solution A new concept in temporary housing has been officially opened in the Netherlands thanks to an innovative project designed by structure specialists Neptunus.

Sophisticated technology, originally developed for the short-term rental of temporary structures to the events and exhibitions industry, has evolved extensively with the flexibility for buildings to host a vast range of longterm commercial uses. Now Neptunus’ creative team has designed an innovative stateof-the-art apartment block which in appearance and quality is virtually impossible to distinguish from a permanent building, yet has the capability to be dismantled and reerected at other locations.

The ‘recyclable flats’ have caught the imagination of the public. All 20 apartments were snapped up within weeks of the housing association opening a ‘hotline’ for people urgently needing living space.

April Trasler, managing director of Neptunus’ UK operation based in Northampton, says she hopes the innovative housing solution created in Holland could be adopted in the UK. She said: “Holland is not alone in facing a shortage of affordable housing and we believe this solution could also be attractive for local authorities in the UK to meet the growing demand for accommodation.”

Dust

–much more than a nuisance!

Silica related deaths are increasing year-on-year, making dust a serious issue.

How can we look to tackle the problem? James Miller explores the matter further

T

here are now more than 650 silica related deaths per year, making it the second largest cause of occupational lung cancer after asbestos. Construction workers have a two to three times greater chance of contracting COPD (chronic obstructive pulmonary disease) than

10 Construction & Civil Engineering

the average due to their exposure to the dust over the course of their working life.

Silicosis (as the lung disease is known) isn’t a new problem. Miners and stonecutters throughout the ages have suffered from its effects. However modern construction processes have seen the impact of these effects increase significantly over recent years as the number of sufferers has risen sharply.

Silica on its own isn’t a problem and is present in sand, granite, cement, stone and other commonly used building materials. However it’s often the case that during the course of construction techniques, such as cutting or grinding concrete and drilling in enclosed spaces, the broken down silica forms

into respirable crystalline silica (RCS).

It is RCS that provides the hazard, which, when inhaled, can cause incurable lung cancer following a prolonged period of exposure. RCS is extremely fine and isn’t visible in normal lighting, which means that, whilst you might think that the air is clear; this isn’t necessarily the case.

The prevalence of silica means that it’s not just miners and stonemasons who need to be cautious in today’s world. Anyone working in the construction industry is at risk, as simple tasks such as sweeping or the pouring of powders can send RCS particles into the air, which can then make their way into the lungs.

Employers have a responsibility to look after their workforce. Not

only does poor preparation in the workplace leave employees susceptible to potential health hazards, it also leaves employers susceptible to future liability claims being made against them. With this in mind then, it pays to be aware of the potential issues that prolonged exposure to silica can cause and to put appropriate safeguards in place.

There are a number of steps that can be taken to minimise the risks presented by working with silica dust; here are my top ten tips:

1. Identify the problem By identifying any potential risk, you’re in the best position to help reduce the impact. List any activities that could present a hazard and consider the possibility of bringing in an industrial hygienist to undertake a full assessment.

2. Use substitute materials As manufacturers of building materials become increasingly aware of the risks posed by prolonged exposure to silica dust, they’re looking for alternative solutions. Opting to use alternative materials that don’t contain silica completely eradicates the risk of silicosis.

prevalence of silica means that it’s not “justTheminers and stonemasons who need to be cautious in today’s world. Anyone working in the construction industry is at risk

”

3. Utilise dust extraction If dust is an unavoidable problem, then read the HSE document CIS36 and take appropriate steps. Mobile dust extractors built to Application Class M (medium) or H (high) help to take out the dust at source and eliminate the need for sweeping, nullifying the risk of it getting airborne.

Use high efficiency cyclone based mobile dust extractors or install temporary vacuum systems that are designed to work in the construction industry with suction guards fitted to power tools to capture dust at source and prevent dusts getting airborne.

Always use construction vacs in place of sweeping and use the vacs to prevent dust getting airborne when pouring powders into mixing vessels.

Complement this approach with

airborne dust cleaners to draw down remaining ambient dust, which can be caused simply from people walking around on site.

The right vacs and air cleaners will not only drastically reduce airborne dust, but power tools will last longer and work better and other trades will not be affected, making the whole site more efficient.

4. Wet it Water is the enemy of dust, so where possible use water to contain any dust in the air. Wet drilling and sawing is advised. Remove dust and debris with a wet vacuum or hose it down.

When it comes to wet concrete coring, products such as stainless steel wet vacs can extract slurry from the coring unit, separate out any debris that’s

Construction & Civil Engineering 11

Health & SAFETY

inside the vac and simultaneously pump away the cleaned water back to a drain or suitable collecting tank.

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

Workers should also be monitored and advised to take medical checkups every two to three years.

6. Be hygienic Crystalline silica has the capacity to stay on hands and clothing during the course of contact, so whilst this might seem like straightforward advice, it really is as simple as washing hands before eating, drinking or having a cigarette. When it comes to the end of the working day, it’s advisable to change clothes and (providing the facilities are available) take a shower to try and reduce the risks as much as possible.

7. Training Education about the matter is key to helping eradicate the problem.

The effects upon health as well as

12 Construction & Civil Engineering

the importance of effective controls and the correct procedures to follow should all be ingrained in a workforce. Any training that you put in place should cover the following key points: l The adverse health effect of exposure to crystalline silica l The importance of putting effective controls in place, safe work practices, and personal hygiene l The purpose of boundaries or signs that identify the work areas that contain crystalline silica dust l How to safely handle, label, and store hazardous materials l The proper use and care of personal protective equipment l How to use dust control equipment effectively

8. Mask up Correctly fitted protective masks should be a minimum requirement in the presence of silica dust. FFP3 masks are recommended as they filter at least 99 per cent of airborne particles. Make sure that, not only are they distributed amongst the workforce, but also that they are properly fitted and worn in the appropriate areas.

9. Effectively communicate The presence of crystalline silica needs to be clearly labelled; if it’s in a greater concentration than 0.1 per cent then a safety data sheet must accompany any products where this is the case.

10. Signpost it If crystalline silica is present, make sure that the area is clearly marked and that warning signs indicate the potential hazard so that workers are aware of the risk. Any personal protective equipment that’s required should be clearly identified and easily accessible. m

Billion-dollar building With the latest generation of highrise buildings reaching new heights of over 600 metres, the supertall construction boom is bringing new challenges as new projects are built higher, faster and with increasing complexity. As the (re)insurer of a number of the tallest buildings around the world, including the next building to hold the title of ‘world’s tallest’, the one-kilometre high Kingdom Tower development in Jeddah, engineering insurer Allianz Global Corporate & Specialty (AGCS) analyses the challenges of assessing and managing such exceptional risks in its latest Supertall Buildings Risk Bulletin.

Alongside the continuous race for record heights, a strong geographical construction shift east is taking place. While throughout the 20th century the US skyscraper dominance was undisputed, the vast majority of construction projects today are in China, South East Asia and the Middle East. Dubai alone is already home to 20 per cent of the world’s tallest 50 buildings, while China boasts 30 of the tallest 100 buildings across 15 cities. Indeed,

in June China announced initial plans for its own one-kilometre tall building, the Phoenix Towers.

“The eastward trend is set to stay, driven by rapid economic and demographic growth, urbanisation, strong investor appetite for flagship real estate assets and lower labour costs than in the traditional Western markets,“ explains Ahmet Batmaz, global head of engineering risk consulting at AGCS. Ground-breaking projects bring uniquely challenging risks for insurers, as well as for architects and contractors, which is why AGCS engineering risk experts underline that no two tall building projects are alike. These constructions are inherently highly complex, as they can involve up to 10,000 workers and over 100 subcontractors each. Data availability and accuracy can be an additional challenge, principally in newly developed economies.

For further information take a look at the bulletin: http://www. agcs.allianz.com/assets/PDFs/ risk%20bulletins/SupertallBuildings-Bulletin.pdf.

Improved facilities WSP has been appointed to support Skanska in creating the Premier Inn Clinical Building at Great Ormond Street Hospital for Children (GOSH), completing the Mittal Children’s Medical Centre. WSP will be providing structural and services engineering services, having previously worked with GOSH on the detailed design.

The new building is part of an on-going programme to redevelop some of the oldest parts of the hospital, replacing outdated wards with world-class facilities and providing more space for parents to be with their children. As the main contractor, Skanska is responsible for the design, construction and mechanical and electrical fit-out of the facilities, which will offer 116 beds, two integrated operating theatres and a post-anaesthesia care unit.

The project will be delivered in a live hospital environment. To minimise the effect of the building project on hospital operations, patients, visitors and surrounding residential areas, the team will use techniques that minimise noise, dust and vibration.

WSP project director Alistair MacFarlane said: “WSP have worked closely with GOSH to provide detailed design and we are now excited to move this project into the construction phase with Skanska. This is a challenging project, particularly how you design and deliver a 21st century world class healthcare facility on a restrained central London site. We look forward to working towards the successful completion of the Premier Inn Clinical Building and providing the superior accommodation and environments that staff and patients deserve.”

Fence contract A British high security fencing systems manufacturer has won its first two pilot projects, worth almost £1.5 million, with Oman’s premier oil company.

Zaun Limited is supplying the perimeter security for two prestigious booster stations in Oman for Petroleum Development Oman (PDO), the foremost exploration and production company in the Sultanate. It accounts for more than 70 per cent of the country’s crude oil production and nearly all of its natural gas supply.

Zaun is supplying almost nine km of HiSec 358 fencing and a large number of PAS 68 crash rated entry and exit gates, which will fill 24 40foot containers, of which half have already left Zaun’s UK manufacturing base.

The fencing and gates will be integrated with razor wire, PIDs and CCTV to form inner and outer cordons around the Hubara oil booster station in the south of Oman and its sister Nahada booster station in the north, about 400km from Muscat towards the Saudi border.

Jeremy Knight, head of Middle East operations for Zaun, said: “Even though these are only pilot projects, they constitute a sizable contract for our Middle East operation. PDO is an extremely important and influential client for Zaun as they are well known in the region for setting the benchmark for the industry.”

Work on both sites is expected to complete later in 2014, when PDO has plans to roll out security on further sites across the country.

Safe on site?

Philip O’Leary answers a thorny question - are our scaffold boards currently safe?

I

t was both daunting and encouraging when BM TRADA was asked by one of the country’s largest blue chip companies and users of scaffold boards – tens of thousands at several sites across the UK – ‘are our scaffold boards currently on site safe?’.

Daunting, because there was no clearcut answer. ‘No’ would have started an unreasonable panic, yet ‘yes’ was not necessarily strictly true either.

Philip O’Leary, head of BM TRADA’s Timber Technology Investigations, takes up the story. “We had inspected

14 Construction & Civil Engineering

a sample of scaffold boards after being called in to investigate why a board had broken in service – so it was encouraging to find a company taking its responsibilities for health and safety on site seriously enough to sit down with us and review the safety issues,” he says.

On site, often grey with cement and covered in dirt, scaffold boards are almost beneath notice, yet how spectacularly they will hit the headlines if they fail! The modest scaffold board enables workers to carry out their work, at height, safely,

on a building under construction or refurbishment. Failure can lead to risk of serious injury or even death.

What is of equal concern - and what end users must be mindful of - is that scaffold boards are often hired or supplied to site by people who have little or no knowledge of timber.

Generally made of European whitewood, new scaffold boards are cut to certain dimensions within given tolerances and graded using British Standard BS 2482:2009.

At this point they are fit for their

intended purpose – though even then they may not look pretty.

Grading is for strength not appearance and ‘defects’ such as knots and wane are allowed within certain parameters. Anyone hiring or using scaffolding needs to be able to trust their supplier on this.

Used scaffold boards are expected to look scuffed and worn and still provide long service.

However, if they have been ‘abused’ on a previous job, at first glance they may appear just the same as those which have been battered about a

bit that can still do the job safely.

How do you tell which is which?

Another problem is the reality of the construction industry. “When scaffolding is hired out, more than likely with only a short turnaround between projects, it may be given no more than a quick clean and cursory inspection by untrained operatives, then delivered to the next site,” says Mr O’Leary. “In BM TRADA’s view this is by no means good enough. It needs someone who knows what to look for when checking that the boards are still fit

for purpose - and that demands more than removing any obviously broken or damaged ones. Damage can occur in several ways, for example if boards have been overloaded or stored in a way that results in wood decay.”

BM TRADA feels so strongly about this that it added a one-day Inspection of Used Scaffold Board course to take out to site to its training portfolio. The course looks at the principles of grading, inspection techniques for used boards, storage methods and guidelines for issuing used boards for re-use. It ends with a practical inspection of used boards at the client’s yard. Suppliers, too, can play their part by urging vigilance among customers and by ensuring that only correctly graded boards without features/defects that are detrimental to strength are allowed to enter the market in the first place.

“It is important for companies to understand how to inspect used boards to ensure that they are maintained to a high standard and, most importantly, are safe to use. In many cases the people responsible for the task are not timber specialists, so training is key,” says Mr O’Leary.

The course content includes: an understanding of the grading principles in BS 2482:2009 Specification for timber scaffold boards; a full description of the grading rules; a comprehensive description of defects in softwood; evaluation methods; specifications; marking; inspection techniques; and correct methods of storage.

The next course takes place at BM TRADA’s High Wycombe headquarters on 5th November. The course costs £189 + VAT for nonmembers and £169 + VAT TRADA members. Courses can also be held on client’s premises. m

loud seems to promise everything businesses need from their IT infrastructure.

It transfers costs from Capex to Opex while offering limitless capacity, almost total flexibility and increased efficiency.

But what exactly is it, and how can businesses use it for optimum benefit?

The US National Institute of Standards and Technology definition says: Cloud computing is a model for enabling ubiquitous, convenient, ondemand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

One of the best things cloud

16 Construction & Civil Engineering

does is get business units out of the business of making IT decisions. In an ideal case, they define the application or service they require, with relevant service level agreements (SLAs). They then leave all the other decisions (how and where the service is hosted, platform, operating system, resilience etc.) to their IT colleagues.

Cloud also offers significant scalability benefits; there are fewer limits, and with true cloud you simply pay for capacity as you use it. However, organisations need to understand that implementing cloud is not simply a matter of handing responsibility to someone else. They still need to define each service before they can move it to public or community cloud, and their historical legacy will not fit neatly.

One of the key inhibitors for

cloud service take-up is concern about security. In most cases these fears are overstated, and most are more general risk management than security. The majority of cloud service providers will implement and manage considerably better IT security controls than internal IT departments: l Ensuring good security is vital to the success of their business.

Most reputable providers hold and maintain ISO27000 and PCI DSS best practice information security certifications l Many have pan-Government security accreditations, which require them to be regularly security tested by independent government approved testers l They can afford the best security technologies and staff, as the costs are amortised across all their clients.

The more important aspect of security is supplier risk management, which is reliant on the supplier’s financial security and terms of contract.

Suitable services for the cloud I believe organisations should implement a hybrid cloud solution, reserving public cloud for low risk, less critical services and running other services from a trusted third party or in-house. Once the organisation is familiar and comfortable with cloud concepts and practices, and have tested public cloud, they can consider moving more services.

Good services to move to the cloud are: l Archiving and long term data retention l Capacity on demand l Specialist applications l Shared applications e.g. extranets l Short-term projects e.g. application development and test environments l Start-ups/new ventures l Disaster recovery To prepare for hybrid cloud, organisations should run the service on a virtualised platform, and use standard interfaces for e.g. authentication and communication.

They also need to get their service management capabilities right.

Ideally the service characteristics should be properly defined and transparent, where possible using standard, open interfaces e.g. XML, SOAP, REST, SAML etc.

Vanilla or managed cloud?

The organisation then has to consider whether it wants to hand management responsibility to the cloud provider or continue to manage the service itself.

With ‘vanilla’ cloud, a third party provides capacity in their data centre and may provide selfservice tools, but the organisation still manages and monitors the service itself. It does not include

application specific security or anything else tailored to the organisation’s particular needs.

Many cloud services cannot handle all aspects of infrastructure and applications – especially when an organisation has 20 years’ worth of legacy infrastructure and data.

In this instance the best option is to choose Infrastructure as a Service (IaaS). The service will not include all the organisation’s data and it will therefore still need in-house monitoring and management.

Richard Blanford is managing director at Fordway. Fordway has over 20 years’ experience helping organisations implement and realise the benefits of IT infrastructure change. The company offers a range of managed cloud services, including a free Cloud Readiness Assessment. All data is held in the company’s two UK Tier 3 data centres and is replicated between them.

Managed cloud services comprise a cloud service with a management layer on top, enabling the organisation to transfer responsibility for all aspects of a specific service or services to a third party provider. The outcome is fixed and predictable costs, internally managed service delivery and clear internally developed, robust SLAs. We call it ‘cloud on the user’s terms’.

Managed cloud services will not suit everyone, but offer an opportunity to reduce the workload of running a complex enterprise network. Organisations can choose a managed infrastructure (IaaS), a managed platform (platform as a service or PaaS) or to have applications provided as part of the package (software as a service or SaaS).

Using managed cloud to support Crossrail tunnelling Team BFK is a joint venture between three of the world’s

leading tunnelling, civil engineering and construction companies - BAM Nuttall Ltd, Ferrovial Agroman and Kier Construction Ltd. It was awarded a number of contracts by Crossrail, including tunnel drives between Royal Oak and Farringdon and the main construction works for the new Crossrail station at Farringdon.

The companies decided it would be best to create an independent IT infrastructure for the project, and chose a managed cloud service from Fordway. Team BFK uses Fordway’s infrastructure in two UK data centres to provide storage and back-up respectively.

Using cloud enabled them to get the infrastructure up and running quickly and provide consistent access for all parties. They can add capacity as needed, only paying for what was used, and can scale back as the project draws to a close. At the end of the contract they will have no residual issues and the environment will be torn down, with data distributed as required. m

f the UK economy is to become substantially greener and energy-secure, those responsible for energy consuming installations (large and small) need to change their thinking in favour of cleaner, more efficient technology. Such is the demand of the Department of Energy & Climate Change (DECC) that advocates both the mitigation of climate change and increased energy efficiency in the face of shrinking fossil fuel resources and rising fuel prices.

That is not to say that organisations are not already improving their footprints, especially when it comes to CO2 emissions from heating and power generation. In fact 4.1 per cent of UK energy is now sourced from renewables, up from 3.8 per cent in 2011 and a third more than in 2009. Between 2012 and 2013, the Government’s provisional estimates indicate that carbon dioxide emissions decreased by 7.5 per cent in the energy supply sector following a reduction in fossil fuel use for electricity generation. However, the industrial and commercial sectors alone account for over half of the UK’s CO2 emissions, and those from the business sector even increased by 2.9 per cent in 2013. Hence there is further potential for energy conservation across sectors.

Over the past two decades, combined heat and power technology (CHP) has emerged as one cost-effective, carbon efficient strategy. Heavy energy consumers such as manufacturing sites and large hospitals were first to

come as a surprise that their deployment as a fast-track energy efficiency tool is attracting businesses and public authorities alike � recognise its benefits. Now housing developments, universities, retail parks and smaller sites where there is a ready demand for heat as well as power, are also following suit.

Most recently a mix of fiscal and financial incentives including Climate Change Levy (CCL) exemption, the non-domestic Renewable Heat Incentive (RHI) or support from the Renewables Obligation (RO) for renewable CHP technology have aided the uptake of cogeneration as an energy efficiency measure. Conveniently, it is not only a lower carbon solution for new commercial builds that are designed with efficiency in mind. CHP also presents a viable approach to improving the footprints of older sites where energy and estates managers often CHP plants often require infrastructure works to the site HV electrical and heat main networks

Larger CHP installations on existing sites can require civil works - this picture shows the base of a new flue for a 4.2MWe CHP need to contend with old equipment and a tired building fabric.

The way CHP achieves carbon and cost savings is as simple as it is effective: It simultaneously generates useful electrical and thermal energy from a single facility.

Capturing the heat that is produced

as a by-product during the electrical generation process to heat water for local use, the CHP plant makes more efficient use of its primary fuel source. This achieves an energy cost saving that can be as high as 35 per cent p.a. depending on the current tariffs for fuel and imported power, whilst it also lowers the quantity of CO2 emitted during what would be traditionally two separate fuel-consuming processes. As an added bonus, transmission and distribution losses associated with the National Grid are avoided, as CHP units are strategically located at the point of use.

As a rule of thumb the heat load available to the CHP should surpass 3500 hours/year to make the application worthwhile. That said, heat loads will vary throughout the seasons and even the day. Therefore CHP installations should be scaled according to the individual heat loads available onsite to yield optimum energy outputs and project returns.

CHP schemes already start to pay back after three to five years, so it does not come as a surprise that their deployment as a fast-track energy efficiency tool is attracting businesses and public authorities alike. Small-scale packaged CHP are particularly sought after because their installation is rapid, returns are guaranteed and the energy services provider typically manages operation and maintenance, taking the hassle out of plant management. Anything from 130kWe up to 2MWe can be packaged to suit small, medium and larger projects without the need for a bespoke design-install approach.

generation technologies including steam turbines, gas turbines and reciprocating engines that commonly burn widely available but un-replenishable natural gas. CHP technology is evolving, however, to accommodate alternative fuels, namely biomass, to counter volatile gas prices and to mitigate environmental concerns surrounding fossil fuels.

Processed wood pellets and wood chip are the preferred options here because they are plentiful, low-cost and readily available. And yet their production for use in energy generation is not without its controversy, with some arguing against the volume of embodied carbon tied up in their production process.

Then again, a pioneering business model is seeing the recycling of life-expired or used wood from the local authority waste transfer, construction, packaging and furniture sectors.

This wood does not have the same embodied carbon as energy crops that are grown and harvested solely for pellet production. Instead, it is diverted from a waste stream that would otherwise see this volume sent to landfill. Eventually, the processed pellets or chips are delivered to CHP plants according to demand, provided that the site allows for regular delivery and storage of the fuel.

Despite these advantages biomass-fuelled CHP units currently remain suitable only for 2MW+ sites and more often than not require a back-up fuel to either bridge

Consequently, it is essential to seek specialist advice to determine which size conventional CHP or biomass CHP will be the most suitable solution for commercial and industrial sites or public facilities that intend to adopt efficient, lower-carbon technology.

Energy management services providers will also be able to advise on costing and financing a CHP development, reviewing the best method for establishing the capital, fuel and maintenance costs.

The investment in buildinglevel heat technology may seem a big step, particularly at older sites, but the achievable cost

savings are persuasive, if not the move towards decarbonised heat, which could see the premises of any organisation contribute to a greener UK economy. m

Access to funding In June 2014 it was announced that construction businesses across the UK are being offered co-investment to help develop new ways of boosting management skills in their sector.

A total of £4 million is available through the UK Commission for Employment and Skills (UKCES), as part of an ongoing governmentbacked programme to encourage employer-led solutions to persistent skills problems.

Nigel Whitehead, group managing director of BAE Systems and a commissioner at UKCES, explained: “Our research shows that the UK lags behind its international competitors when it comes to management skills. That matters. It matters even more in the construction sector because it’s such an important part of our economy. Good management practices boost productivity, staff engagement and ultimately drive economic growth. And

while the UK’s best firms may be world leading, the sad truth is that, generally, management capability in the UK’s construction firms isn’t as good as many other countries, particularly the US. “But improved management isn’t something that can be imposed on business. It needs to be led from within. That’s why we’re making up to £4 million coinvestment available to businesses to help them find innovative and effective ways of working with their networks or supply chains to boost management and leadership capability.”

The competition is open to organisations in the construction, manufacturing, financial and legal sectors, and the UKCES expects to invest up to £300,000 per successful proposal.

The closing date for submissions is 30 July 2014.

Unique and innovative One of the UK’s leading designers and manufacturers of carbon fibre and composite products has successfully engineered a highly complex and ambitious carbon fibre lighting sculpture for the Caviar House & Prunier seafood bar and restaurant in Heathrow’s new Terminal 2. The terminal opened on 4th June, with the Queen officially opening the terminal on 23rd June.

Polar Manufacturing Limited (PML), based in Norfolk, was commissioned by Cinimod Studio, who designed the sculpture and specialise in the fusion of architecture and lighting design.

The lighting sculpture is named ‘Emergence’ and, with playful relevance to Caviar House, captures the re-imagined movement of a school of fish moving underwater. The audacious structure, comprised of LED arcs spiralling nearly 13 metres up to the ceiling, utilises a transfer of technologies from other industries, borrowing heavily from the engineered carbon fibre composites, as found in the newest airplanes.

Cinimod commissioned PML because they not only quickly responded to their brief, but agreed with their recommendation to make 95 per cent of the structure from carbon fibre.

Life saver Residents and workers in skyscrapers and other tall buildings are often trapped in case of a fire, as 9/11 demonstrated. The newly developed Evacuator offers a last resort, allowing them to slowly and safely descend on a steel cable at the outside of the building. Worldwide the device can save thousands of lives, from residents in tall buildings to mechanics in wind turbines.

The Evacuator was presented at the International Tall Building Fire Safety Conference at the University of Greenwich, in June in London. Furthermore Discovery Channel is making a documentary about the Evacuator, which is due to be broadcast later in 2014.

Dutch inventors Eugene Verstegen and Joris Veeger came up with the idea when they saw people fall to their death from the Twin Towers in New York.

Together with a professional engineering company they developed a fireproof steel winch, which is guaranteed to work at all times, even when electricity is down. The device allows four persons at the same time to descend 50, 140 or 300 metres. They automatically descend in a safety harness on a steel cable, at a speed of one metre per second. The Evacuator is people’s last resort if elevators are switched off, emergency exits are filled with smoke and firemen can’t reach them.

SPECIAL FEATURE

Theright

connection The costly mistakes construction companies and developers make when it comes to energy infrastructure. By Simon Phipps

C

onstruction companies and developers have very simple needs when it comes to utilities. They want them connected, as that’s when they can collect their money. However, when it comes to energy, there are many ways money can be wasted getting to that point. Here are some of the fundamental industry mistakes developers and construction companies make when procuring energy infrastructures.

Load Assessment One early mistake that crops up is at the design stage where there can be a mismatch between energy levels requested by the site and the amount made available from the point of connection. The fundamental issue is that sometimes there can be two different parties designing the

22 Construction & Civil Engineering

Simon Phipps

infrastructure and if they are out of sync it can create major problems and delays.

The energy connection process can only begin when a developer employs a consultant to design and procure the required utility infrastructure. This consultant could be a specialist, but in most cases they are mechanical and electrical (M&E) professionals, trained to design and procure infrastructures downstream of the meter and sometimes within the building. These consultants will never design or acquire infrastructures upstream of high voltage works. These upstream infrastructures will have to be designed by a utility provider or an independent connections provider.

If it is a utility provider, they will work in a very different way from an M&E consultant, which is where a mismatch creeps in.

For instance when a utility provider

is tasked with designing and procuring the infrastructure they will diversify the required load at a number of points throughout the system. The utilities provider, for example, within an apartment block will diversify at the riser, the substation, the point of connection and potentially the primary. Whereas the M&E consultants will add up the appliances in each apartment and then diversify that load adding further diversification for the site.

This mismatch of approaches could needlessly inflate the energy load requested for the site. If there is too much load being requested then the point of connection will need to be higher up the network or require an element of reinforcement. So having two parties designing the infrastructure carries a risk. It is much better to have one party, who is capable of designing it all.

Contract When organisations become involved in a multiple occupancy development – both commercial and industrial projects simultaneously the occupier will enter into a contract with the developer. Within these contracts it will usually state that the developer must provide a unit, serviced to an agreed level. That level will normally be provided by the occupier’s consultants and form part of the development contract.

Developers will then enter into a contract with the utility provider directly or with a main contractor in order for them to provide the energy connection for the site. If the sum of all the occupiers’ utility requirements does not match the total for the site, it could be said that the developer is not providing sufficient capacity. This could become an issue in the future if the occupier decides that they would like to expand, as it may result in the occupier having to pay a significant reinforcement in order to do so and the developer could be liable to cover this cost.

Timing Developers do not want to commit funds to a project and then wait a long time to recover that money.

So, as the utility connection is a significant upfront cost, orders are normally not placed until planning permission has been achieved.

Unfortunately when planning permission is finally obtained and construction is allowed to begin, connections are needed fast.

Especially as in the development world it is the connection of utilities that allows the project to complete and the monies to be drawn down.

However the grid connections are not in place and ready to go. So developers should secure the utility connection as soon as possible to avoid delays in the development programme.

Construction Agreement Due to a lack of investment in the past, the majority of utility infrastructures are now operating

at overcapacity and are stretched beyond their limits. This is creating huge issues within the electricity market. There are certain areas where if a quotation to connect a development is not accepted within a 90 day validity period, the point of connection may be lost and grabbed by a rival developer. There have been a number of sites where this exact mistake has occurred and it has caused the costs to spiral. In one recent case the additional cost was £300,000.

Redevelopment of Old Buildings Another issue that crops up is the redevelopment of old buildings. This is due to the industry P26 security of supply regulations, which changed a few years ago. If a new connection is made to an existing network, that network has to comply with the new regulations. This can have big implications for redevelopments.

For instance if you knock a building down that has a 1000kVA supply and the new building replacing it requires the same or less supply, it is not guaranteed that the same connection will be available, as the network upon which it depends may not comply. Remedying this mistake can be expensive, involving network reinforcement.

Regulatory All utilities operate within a very strict regulatory framework and it is very difficult for them to be flexible.

It is important that developers understand this framework to avoid any confusion that could significantly delay a project or increase the cost.

For instance distribution network operators (DNOs) have to operate within a very strict first come first served process. If you make an application for a connection and that offer expires, you will need to reapply and that application will go to the bottom of the queue. Failure to have cleared funds in the DNO bank account prior to the offer expiring will mean your acceptance will also be rejected.

Thinking Outside the Box Many developers still see a DNO as the first port of call to design and provide their connection. However with deregulations it is no longer the case and so going with an independent connections provider may be a better route as they can often be more nimble and flexible than a DNO. For instance a housing developer in Greenwich was looking at using a DNO to provide grid connection. However the DNO had a policy that no substation was to be situated in basements. The DNO’s risk averse business model saw basements as a confined space therefore only trained personnel could work in the substations. So going with the DNO would have involved placing the substations on the first floor, which was prime real estate for the developer. When we at Dragon looked at this challenge, we came up with a solution, which situated the seven substations required in the basements. We also helped the client negotiate for an IDNO, who was comfortable with this solution, to take on the network once it was complete, enabling the development’s value to be maximised.

As you can see, energy infrastructure is not as simple as it sounds. Which is why my last piece of advice would be to work with the correct consultants and specialist contractors so that all the above can be overcome. m

Since the company first began in its headquarters located in Stockholm it has provided the region with aggregates and today has expanded to also include operations within the Gothenburg, Gävle and NorrkÜping regions. In all Jehander operates pits at 22 locations across Sweden, which are dispersed between its four operational regions.

Although the company continues to operate its key market in Sweden, operationally the company has undergone several changes over its long history. The most significant change in the running of the business came between 2003 and 2004, with the decision

to integrate the four companies operating into a single business that would take on its current name of Jehander. “The company looks very different today from how it did when I joined the company in 2001,” says managing director Pär Åström.

being responsible, profitable and transparent.”

The aggregates supplied by Jehander typically derive from gravel, sand and macadam (crushed rock) and are key ingredients in asphalt and concrete construction.

Aggregates are often required to be on hand for such diverse applications as building and highway maintenance, road gritting, water purification, and flooring.

Despite the challenges of the global economic slow down that began during 2008, demand of aggregates has continued to remain strong in Sweden. Furthermore as confidence begins to return to the market and build projects and infrastructure upgrades are becoming reinstated, the demand for building materials is set to increase still further. During 2005 80 million tonnes of aggregates

were delivered throughout Sweden, today the amount required yearly in Stockholm alone is placed at around 11 million tonnes. Projects like the construction of a new Stockholm bypass, scheduled to commence between 2015 and 2016 will increase present requirement of aggregates yearly by several million tonnes.

“The new bypass will see 20 million tonnes of rock flowing into the area via road and by port. We are the only company in Stockholm to have vessels and we have two quarry sites along Lake Mälaren and therefore can deliver by boat instead of just by truck,” Pär elaborates.

“This will be a large project, which will increase the market from around 11 million tonnes in Stockholm by a further two million tonnes per year for at least the next five to six years. Although no contracts have yet been awarded, we feel that

Jehander is in an excellent position to be apart of this.”

Trading conditions have remained challenging throughout the construction industry during recent history, for a number of reasons. Firstly the global downturn has naturally had far reaching effects leaving precious few markets unscathed within the construction sector. Additionally, 2013’s harsh European winter further compounded trading conditions with decreased windows for construction and a sharp rise in demand for winterised products.

Despite the challenges this posed, Jehander was keen to not leave its customers wanting. “We had a very harsh winter last year that seemed to go on for six to seven months, which was quite a struggle for us,” Pär says. “However the business has always been very customer friendly and focused, so when customers demand for certain products is high we have always tried to make sure we can make the client happy and offer a good supply. So when winter grit was in demand we produced a

lot of it for market, which was very expensive.”

Furthermore a key market challenge in Sweden concerns the levels of natural sand and gravel present in the nation’s territory.

“Within Sweden there will be a lack of natural sand because sand and gravel beds are essential for water supply and local authorities have called for a reduction in the extraction of natural sand - the UK has the same problem. There is a tax on natural sand, which makes it an expensive product to produce and it is not possible to get a permit to open new pits so the supply is limited,” Pär says. “There is a need to have new products to compensate; one of these is to crush rock so it

has almost the same properties as sand so that it can be used in concrete instead of natural sand.

We call this manufactured sand and we crush the rocks to be rounder as to perform more like natural sand.”

Products like this coupled with a focus on high-demand regions such as Stockholm and Gothenburg have enabled Jehander to weather the challenges to the market and continue to remain strong.

Throughout its 140 year history the company has demonstrated an ability to adapt to the needs of its client base and innovate solutions to best the challenges of the marketplace. As the market begins to move again, it has a strong foundation that is set to last well into the future. m

ell Equipment manufactures and supplies the most reliable; most fuel efficient and most technically advanced articulated dump trucks (ADTs) in the world.

The company’s products bring together the very best in power and drivetrain technology and efficient, innovative design. They are created to be dynamic vehicles that more than double their weight when loaded, which means they can economically deliver extra production or offer, as Bell describes

it: ‘absolutely the lowest cost per tonne in the business’.

With a customer base ranging from the quarrying, mining and construction sectors to waste, recycling, energy and general plant hire, Bell Equipment is able to draw upon years of experience in a range of sectors in order to ensure its trucks meet the needs of its end users. With industry leading technology and reliability built in, Bell Equipment’s ADTs have a renowned reputation. Its current offering comprises two ranges – the proven D-series (currently in its Mark

VII version) and the brand-new E-series, the next evolution in Bell design.

Building upon the strength and reputation of this range, the company also introduced a range of reliable and efficient wheeled loaders. This comprises a total of seven machines and has already received critical acclaim from the construction, quarry and recycling markets.

A perfect illustration of the high quality of these machines is the decision from Barry Wood Plant Hire (better known as Woods) to demo a Bell wheeled loader at the Hillhead 2014 exhibition in late June.

This leading international exhibition saw companies presenting the latest plant, equipment and materials, and Woods put the newly purchased Bell Equipment L2606E wheeled loader at centre stage on

its stand. It performed a series of demonstrations and gave visitors an idea of exactly what the L2606E – the largest loader supplied by Bell – is capable of, from stockpiling and re-handling, to movability around the often tight restraints of crushing and screening sites.

In addition, a second next generation E-series machine was on display on Bell Equipment’s own stand. The E-series was officially launched in the UK in late 2013 and instantly proved its credentials. The next generation in articulated dump truck design and technology, the E-series builds upon the proven legacy of the successful D-series, in order to deliver increased production payloads, lower daily operating costs, superior ride quality and uncompromised safety standards.

and European Union. Ahead of the launch of the legislation, Bell used Hillhead to demonstrate how this necessary evolution in emissions technology is being integrated to complement the existing advantages of Bell loaders.

“With Tier 4 being introduced specifically to tackle emissions, it is more important than ever that customers seek a machine that can meet the range of complex and demanding tasks expected of modern loaders,” explains Nick. unrivalled fuel efficiency – a quality that has already seen the E-series selected for use by major names in quarrying, earthmoving and plant hire. “The E-series is even more remarkable in real-life than we promised [in 2012],” noted Nick Learoyd, managing director

of Bell Equipment.

Bell also used the Hillhead event to highlight the environmental credentials of its wheeled loaders.

2014 is a year of change in this market with the switch to full Tier 4 engines in line with the clean air regulations established by the EPA

Groeneveld UK Limited Groeneveld UK have a long standing relationship with Bell Equipment UK Ltd providing our world leading “Twin” automatic lubrication system helping to keep Bell’s machines in optimum condition in harsh environments. We look forward to continuing that relationship with new and innovative products and services, from automatic lubrication to active safety systems and engine oil management all helping to drive and improve business efficiency.

“Regardless of their class of engine, Bell loaders can meet and exceed those expectations.”

This degree of innovation and dedication to design is greatly appreciated by a loyal customer base, who after their first purchase, frequently return to Bell for subsequent machines. Woods, mentioned earlier, has seven Bell articulated dump trucks in its fleet, and four of its nine loaders are from Bell. Another customer, Levenseat, a waste management and materials recycling business operating from two sites in central Scotland, also added more of the company’s equipment to its fleet in May 2014 when it ordered a new Bell ADT. The machine represents the third Bell ADT purchased Levenseat, but it is the first E-series. “This is another brilliant result for the E-Series,” says Sandy Fairweather, Bell Equipment’s sales manager in Scotland. “And no wonder. The B30E ADT can tackle tasks that would confound other machines. It’s a high performing truck that’s powerful, fuel-efficient, hard-wearing and a pleasure to operate.”

Sandy added: “It’s also the first time Levenseat has used the Fleetm@tic system, and already it has presented key information that will assist with productivity, as well as cost-efficiency.” Fleetm@tic is an advanced and user-friendly fleet management system that enables customers to accurately monitor their fleet from anywhere in the world – helping them save both time and money. It can provide basic data such as machine hours and average fuel burn to more detailed information such as individual tipping reports. Fleetm@tic is the only such system in the world that is able to link machine performance with actual tonnage moved.

Bell equips all ADTs with a free entry-level Fleetm@tic package as standard, though customers have the option of upgrading to a subscription package if they require more detailed reporting capability.

Fleetm@tic also allows owners to

monitor the exact location of each machine, set virtual geo-fences around their ADTs and monitor individual driver behaviour using unique driver ID codes.

“To us, this further demonstrates Levenseat’s confidence in our equipment and we are positive that they’ll benefit from many productive years from the truck, irrelevant of

challenges it’s presented with,” Sandy concluded.

Bell Equipment has now established itself at the forefront of the industry, with the D series dump truck widely regarded as the market leader, and the E Series already gaining a following. Not just based in the UK, Bell is continually increasing its customer base across the globe, supported by the recent creation of Bell Equipment North America. In addition, the company’s UK division is directly responsible for a number of foreign dealers and distributors, encompassing Ireland, Iceland, Norway, Israel and the Middle East. “Bell is increasingly a player in diverse markets around the world,” confirmed Nick. Today Bell Equipment is a truly international company with users of more than 19,000 machines operating in over 60 countries around the world. As the construction and civils market continues to improve, the company looks forward to supplying both new and existing customers with its innovative and exceptional equipment. m

PM is one of the leading manufacturers of wood products in Europe and a forerunner in research and development in the area. The merger of Kymmene Corporation and Repola Ltd and its subsidiary United Paper Mills Ltd formed UPM in 1996 and today it is a leader in the integration of bio and forest industries into the new, combined sustainable and innovation-driven ‘biofore’ industry.

UPM’s structure consists of six business areas - UPM Biorefining, UPM Energy, UPM Raflatac, UPM Paper Asia, UPM Paper ENA (Europe and North America) and UPM Plywood – and in 2013, UPM’s sales exceeded ten billion euros. The organisation is present in 65 countries, with production plants in 14 and it employs approximately 21,000 people worldwide.

In the area of wood, UPM is one of the world’s leading forest industry groups, and through its three wood-based divisions,

with this material for over a century, since the founder of UPM’s plywood business, Wilhelm Schauman launched his first mill in 1912. The company Schauman created was not the first producer of plywood, but it introduced large scale and up-to-date manufacturing processes to Finland. Schauman soon became the market leader and by 2014 UPM had become the largest plywood manufacturer in Europe, with its plywood and veneer products being sold across the world under the registered trademark WISA. One of the foundation stones laid

by Schauman was a dedication to research and development (R&D) and this has become part of UPM’s daily process. Innovation is at the core of its growth, and in order to ensure it is meeting the needs of the customer and predicting the needs of the future, some four decades

ago a dedicated R&D department was established, and since that time its development work has been conducted systematically.

By combining the latest scientific knowledge with its long experience in plywood and veneer panels the organisation is able to keep its product range up-to-date and ready to meet new challenges. This methodology is also a core part of its new product introduction programme.

One of the latest releases from this division is UPM Grada, a thermoformable wood material for the form pressing industry. Grada technology revitalises the forming of wood with heat and pressure and opens up new opportunities for designs not achievable with traditional methods. UPM Grada’s unique forming properties enable high quality and ecological designs, which are also visually appealing.

This product has recently been further developed, with the launch of UPM Grada 2000, the newest member in the product family, which requires only 950C forming temperature and consequently further improves the form pressing process efficiency and saves energy simultaneously.

“At UPM we focus on developing Grada technology so that our customers can improve their competitiveness by making their manufacturing more efficient.

The new development supports manufacturers, who are looking into possibilities to transfer manufacturing back to Europe from

low cost countries. The improved product series has been tested by many of our customers and they are very pleased with the fact that their process cycle-time improves at least by 25 per cent,” explains Mikko Tilli from UPM. The significantly lower forming temperature makes it possible to use more delicate coating materials on the panel. Since the material needs to be heated to lower temperature, there are more options on heating equipment than before. “I’m delighted that UPM Grada can now be used in more versatile ways and the technology can be easily accessed by many new customers,” added Mikko.

Given their pedigree, innovative nature and very high quality, it is not surprising that UPM’s plywood are very popular solutions in the construction industry. The company has extensive experience and deep insight in building and working with plywood and it offers a wide range of solutions from framework panels

to exterior and interior building as well as a complete range for concrete castings. In addition to heavy construction, WISA products and solutions are suitable for smaller scale building and construction projects.

Although the company’s main market is Europe, WISA products have been utilised on a global basis and WISA plywood products’ reputation in China is quite literally built on the foundation of the country’s most iconic skyscrapers such as the Shanghai World Financial Centre, Shanghai International Financial Centre and the latest masterpiece, the world’s second tallest building, Shanghai Tower.

WISA-Form Birch plywood panels were used in all these prestigious buildings for casting the concrete. WISA-Form Birch was chosen by the contractors because of its strength and consistent performance, but also because of the high number of re-uses and long

service life - both essential qualities for long-lasting, multimillion dollar construction projects led in critical weather conditions.

By taking advantage of the best characteristics of birch and coniferous raw material, modern production methods and the knowledge and experience of its people, UPM can offer hardwearing and ecological WISA solutions to not only partners in construction such as those mentioned above, but also those in transport and many other industries. UPM’s unique combination of WISA and wide range of professional services mean that its customers can improve their cost, material and energy efficiency easily, and it is these benefits that ensure customers return time and again. m

aving reached its 50th anniversary in 2013, when it comes to the production of drilling equipment KLEMM Bohrtechnik can draw on years of industry knowledge and experience. The company is proud of its rich heritage of manufacturing in Germany, and used the occasion of five decades of success to launch a new brand slogan - Dynamic Power – and to emphasise the attributes that support it: reliability, customer focus, efficiency and determination.

Under the umbrella of this brand slogan KLEMM Bohrtechnik develops and manufactures hydraulic drill rigs and drilling accessories for all types of drilling jobs in special foundation construction. It produces drilling rigs that are used across the world for foundation and banking work, in the production of roadways both above

38 Construction & Civil Engineering

and below ground, in reservoir dams, on drilling ships and drilling platforms and for the development of renewable energy generation.

The KLEMM Bohrtechnik product range encompasses the whole palette of hydraulic drilling rigs for anchor hole, injections, overlay and double head drilling, as well as the associated hydraulic drifters, rotary heads and double head drilling systems with efficient drilling accessories. Numerous patents, particularly in the area of hydraulic drifters, are proof of the innovation and technical competence that goes into each KLEMM product.

Furthermore, in addition to hydraulic rigs, the organisation also offers sophisticated handling systems for the fitting and removal of drill pipes, and optimally designed drilling rigs for a wide range of drilling processes and drill diameters. As a result, KLEMM can be considered a one-stop-shop for

its customers, who find it efficient and simple to be able to meet their needs from a single source.

First founded in 1963, and acquired

by Ingersoll Rand in 1989, for the past 16 years KLEMM Bohrtechnik has been part of the Bauer Group and is regarded as the Group’s centre of competence for light drill rigs with specially developed components and drilling accessories.

At a recent Open Day held by Bauer, KLEMM was able to enjoy another significant milestone, when it presented the management and engineering department of Stump Spezialtiefbau GmbH a symbolic key to its 50th KLEMM drill rig, a new KR 806-3F. The close relationship between Stump Spezialtiefbau, one of the leading contractors in the special foundation industry, and KLEMM started in 1985 and KLEMM’s management team is very proud of the collaborative partnership that the two companies have created.

This Open Day also saw KLEMM celebrate the hand over of a KLEMM universal drill rig KR 801-3FS to its long-time Norwegian customer Fundamentering AS (FAS). For FAS, who already own five other KLEMM drill rigs, the KR 801-3FS will be the perfect addition to its fleet, and it will be used for micro pile drilling

applications with outer casings up to ø 273 mm.

Alongside the handing over of these impressive pieces of equipment, the Bauer in-house exhibition was also used to showcase another newly designed KLEMM product – the KR 806-5G. Launched in June 2014, the rig has a working weight of approximately 21t and enhances the line-up between the KR 806-3F (approx.

17t) and the KR 807-7F (approx.

26t). Driven by the implementation of the latest emission regulations this drill rig is one of the first worldwide to fulfil the Tier 4 emissions standards, and it features a whole host of new innovations and technology.

Specifically designed for use in the special foundation industry with a focus on tie back and micro pile work, the KR 806-5G has the capability to carry heavy masts and large drilling systems. The newly

designed (and patented) machine kinematics allows for vertical drilling outside of the track area.

Power is of course of the utmost importance to the performance of a drilling rig, and at the heart of the KR 806-5G’s drive train is a six-cylinder Deutz diesel engine type TCD 6.1, which fulfills the latest emission standards (EEC 97/68 EC Stage 4). The exhaust system is equipped as standard with a diesel particulate filter (DPF) and an SCRcatalytic converter to reduce the NOx in the exhaust fumes. Added to the exhaust system is the mixing section between DPF and SCRcatalytic converter, which is used to inject urea (AdBlue).

Another benefit is the rig’s patented power sharing system (also used on the KR 806-3F). The power sharing technology enables an optimal power distribution
