Constructive comment A study carried out by the Health and Safety Executive (HSE), has revealed that around 25% of all UK construction sites are unsafe. Approximately one in four sites failed to comply with safety standards when visited by the HSE, making them unsafe for both the public and employees alike. These are worrying construction accident statistics. During the study, 2014 construction sites received unscheduled visits from HSE inspectors as part of an initiative to reduce death and injury in the building industry. As a result of these visits, 691 enforcement notices were issued at 470 sites and notice was given for work to be stopped immediately on 359 occasions. According to the HSE, over 2.2 million people work in the construction industry. Bearing the results of their study in mind, it is easy to see the alarming potential for deaths and injuries. Ensuring good health and safety practice is therefore vital for every construction site manager - which is why this issue of Construction National is highlighting some of the best site managers in the business whose efforts have been recognised by the NHBC’s first ever awards for health and safety on building sites. Elsewhere in this issue, the case for timber frame is up for consideration. The first prototype homes to reach levels 5 and 6 of the Government’s Code for Sustainable Homes were timber frame buildings. Unveiled at the BRE Innovation Park in 2007, these properties are now three years old and have been put through some rigorous testing. To achieve the right amount of credits to demonstrate compliance with the Code, the key issues affecting a developer’s choice of construction method (typically a choice between masonry, timber frame or steel frame) tend to come down to two things: the energy efficiency of the building’s fabric, which can reduce the home’s overall energy consumption, and the environmental rating and sourcing of the building materials themselves. On both these things, timber frame scores particularly well. Many designers and developers already see timber frame as the most natural solution for Code compliance.

“My father was
horrified....”
A senior manager at one of the UK’s largest construction firms tells how his decision to enter the industry didn’t go down well with his parents, but now he’s proud that his son is a construction apprentice.
n
Many senior people in construction started their careers as apprentices, but their initial training experiences are very different from the support available to young people entering the industry today. Mick Nelson started off as an apprentice at construction giant BAM Nuttall and has progressed through the ranks to become Works Manager for the firm. He told us: “Today’s apprenticeships are very different to those of the 1970s, when I enrolled to become a Trainee Foreman. “My father was horrified when I announced I would be moving to Kings Lynn to begin a one-year residential course as a construction apprentice . In those days, construction was a ruthless industry with a ‘hire and fire’ culture, and, having seen how his friend’s construction firm operated, my father wanted to protect me from this. “Although the content of my course was excellent, I got very little direct support from my employer and had to rely on other colleagues taking me under their wing.”
Tim Box, Quantity Surveying Apprentice at BAM Nuttall
Mick Nelson, Works Manager at BAM Nuttall
The preferred route into the industry for young people has for generations been through apprenticeships and, since the 1970s, they have improved beyond all recognition. But do employers recognise this and the benefits of a modern-day apprentice to their business? Almost a third of employers are cutting back on planned recruitment of apprentices because of the recession, according to new research from sector training body ConstructionSkills. This has led to concerns that without attracting new talent, construction will suffer chronic skills shortages when the economy recovers. Times may still be tough, but today’s apprentices give firms the extra skills that help win contracts and boost productivity. ConstructionSkills apprenticeships combine college learning with onsite experience to ensure that the changing demands of the industry are met. In short, apprentices are good for business and there is nothing to stop today’s apprentice becoming tomorrow’s Chief Executive. The improvement of employer support is perhaps the largest change to apprenticeships over the years, something 19-year-old Tim Box, a current BAM Nuttall Quantity Surveying Apprentice, is benefitting from. Currently enjoying the range of experiences involved in his apprenticeship, Tim considers himself well supported by both cont p8 ConstructionSkills and BAM Nuttall.

ConstructionSkills welcomes Government commitment to apprenticeships n
ConstructionSkills has welcomed the re-allocation of £150 million to fund 50,000 more apprenticeship places for SMEs, in line with Government reforms designed to ‘reduce the structural deficit’ and ‘return the economy to growth.’ Mark Farrar, Chief Executive of ConstructionSkills said: “We are pleased that the Government has prioritised the funding of apprenticeship places to improve Britain’s growth and ensure people are given the best opportunity to access skills and training. Apprenticeships are the lifeblood of this industry and we must ensure we are creating enough opportunities for young people - and that businesses are willing and able to invest in them. “The announcement of 50,000 new SME apprenticeship places goes beyond the 20,000 previously announced and is a welcome boost for the UK construction industry – which contributes 8% of total UK GDP, but which has been battered by the recession.” Construction is the most efficient industry for the public sector to invest in, with every £1 spent generating £2.84 in wider economic benefit. However, the recession has changed the industry, which now needs direct
Government support to recover and deliver broader economic growth. Mark Farrar continued: “We understand Government’s priority is in tackling the public deficit, but it will also be a key task of Government to ensure that public sector investment in key construction-based projects is sustained until the private sector picks up – and it is only by maintaining capital investment in Britain’s infrastructure that we will prevent significant job losses in the sector. “ConstructionSkills has been at the heart of skills and training for over 40 years and we are uniquely positioned to help government deliver a simple, cost-effective and demand-led skills system, for both employers and individuals, that will help pull us out of recession and into a new era of growth.” q

constructionnational from p5 “Getting practical experience with such a large company will be really helpful to kick-start my career and this way of learning suits me. It’s one thing to study something at college, but quite another to actually do it. So I think that the mixture of practical learning and classroom experience in my apprenticeship will give me a great advantage.” Like Tim, Mick thinks that guiding apprentices through their training is important if they are to remain in the industry, which will ensure British construction workers are among the safest and best skilled in the world. Mick added: “Today’s apprentices have a wealth of support available to them, and this is why I am happy for my son to be training as a Plant Mechanic. Unlike when I studied for my apprenticeship, my son is well looked after and the introduction of NVQs in the 1980s means that he has a clear sense of direction. The culture of support is responsible for the high-staff retention rate we have at BAM Nuttall – it’s at 100%. “We insist on the best training and that is why we work with key partners such as ConstructionSkills, the industry’s largest provider of apprentices, who provide courses that really integrate with our on-site practical training. With the industry continuing to change and the skills gap widening, apprentices will continue to be vital for construction over the coming years.” q

The Abbeygate Vizion development in Milton Keynes – Image courtesy of Frosts Landscape Construction Ltd
Green Landscape practitioners from all disciplines are acutely aware of their role in mitigating the environmental and social impact of the built environment. Denise Ewbank, editor of BALI’s journal Landscape News, explains how landscape designers and contractors are embracing new techniques and technologies and working collaboratively with urban planners to deliver environmental sustainability.
n
Amidst the projects receiving accolades at the annual BALI National Landscape Awards in London were commercial and public realm schemes that epitomised our industry’s enthusiasm for, and commitment to, environmental sustainability. The creation of a number of roof gardens as part of the refurbishment of the Ropemaker Place building in London won the BALI landscape contractor responsible, Frosts Landscapes, two awards. Incorporating green roofs into this building presented some major challenges, including craning in 1,100 tonnes of materials – topsoil, plants, turf, paving, aggregates, lighting – and installing permeable paving and a water harvesting system to allow rainfall to be reused for irrigation The Ropemaker Building in and within the building itself.

At the cutting edge of the concrete drilling and sawing industry n
The Drilling and Sawing Association (DSA) represents the interests of companies involved in the concrete drilling and sawing industry and is committed to the improving standards within the industry by establishing better codes of safe working practice, education and training. Diamond drilling and sawing technology is increasingly being used for cutting concrete structures, highways and other construction materials, including steel. DSA members can provide specialist advice and equipment to carry out cutting tasks using diamond tools, which give many benefits, including precision cutting within the shortest timescale, reduced noise, dust and debris and maintenance of structural integrity. By employing a DSA member company, contractors and consultants can rest assured that the firm subscribes to accepted safety standards and carries adequate insurance cover. In recognition of the important part played by specialist subcontractors in safety within the construction industry, the DSA produced a comprehensive Code of Safe Working Practice in 1990. This 80-page document provides a basis for safe working by DSA members and gives detailed guidance on safety legislation, general operating requirements and site set-up. The Code was updated in
January 2010 and is constantly under review. The DSA also provides operator accreditation and training schemes set up in conjunction with the CITB, which result in the issue of Certificates of Competence by the CITB. These show that the individual has been independently assessed in specific categories of drilling and sawing equipment against standards of safety and competence agreed with the CITB. From November 2004, the DSA introduced an Apprenticeship Training Scheme for operators, which provides a formal training programme to agreed national standards. Completion of the two-year training programme qualifies the participants for an NVQ Level 2 in Drilling and Sawing, which then entitles them to a full specialist card. This scheme is currently responsible for training over 100 operators. Now with almost 100 members, the DSA has grown into a powerful organisation promoting the work of professional drilling and sawing contractors and exerting a strong influence on the increasing use of diamond tools to cut concrete and other building materials. More information can be found on the DSA website www.drillandsaw. org.uk or by calling +44 (0) 115 986 7029. q

Timber is not just the future of the construction industry, but the here
and now
by GEOFF ARNOLD,
Despite the change in Government, sustainability looks set to remain UKTFA Chairman high on the agenda. Geoff Arnold, Chairman of the UK Timber Frame Association and MD of Pinewood Structures Ltd, explains the important role timber has to play in not only tackling the Code for Sustainable Homes (CfSH) head on, but also the recent changes to Building Regulations, as well as covering other issues that currently shape the timber frame industry.
n
“As an association we realise that in order to become the number 1 construction method of choice we must face our rivals head on, better their arguments and highlight more than just the obvious ‘green’ argument. “Importantly, the focus has now shifted onto how timber works in real world situations; its thermal performance; the financial benefits of choosing timber frame and how easy it is to encourage the belief that timber is not just the future of the construction industry, but the here and now.”
properties with infiltration rates tighter than 5m3h/m2 at 50pa. “We must not forget the revised Part L & F regulations when looking at build methods”, interjects Geoff. “Timber frame plays an essential role helping designers and contractors meet new targets.” q
Counting the cost of carbon A recent report by the Structural Engineer pitted concrete, masonry and timber against one another and consequently labeled timber as having a high ‘CO2 emission rate after useful life’ - an idea that causes Geoff to shake his head in disbelief. “The Structural Engineer report questions the value of sequestered carbon, but you only have to look at how as an industry timber frame supports forestry, for every tree harvested for use in timber frame three more are planted and Europe’s forests are growing by 661,000 hectares every year as a result. Surely by maximizing the use of wood in construction more sequestered carbon is saved which in turn locks in carbon. The report ignores the issue of embodied energy, an area in which we know timber frame always scores favorably.”
Putting the fabric first A two year continuous assessment of timber frame homes built at the BRE Innovation Park has shown unequivocally that timber frames are ideally suited to the Code for Sustainable Homes (CfSH). “Personally, it came as no surprise to find the first homes reaching Code levels 5 and 6 were timber frame buildings. Timber frame is a perfect fit with the low carbon agenda and more and more house builders are beginning to appreciate the benefits, finding it much easier to achieve very high insulation levels, fewer defects and increased air tightness, all with extremely low embodied energy.”
Regulation timber frame The Approved Documents to Part L (Conservation of Fuel & Power) calls for a 25% cut in carbon emissions compared with current standards for all new developments. The Approved Documents to Part F (Means of Ventilation) sets out to ensure that adequate air quality is provided for people indoors including guidelines for airtight

Royal seal of approval for timber frame n
Stewart Milne Group Board Director, Hugh Mackay, has been honoured for his career-spanning dedication to the promotion of timber frame construction with an MBE in the Queen’s Birthday Honours List. With over 45 years of experience within the UK construction industry, Mr Mackay is widely regarded as being one of the forefathers of modern timber frame, and is
credited with being a founding member of the UK Timber Frame Association (UKTFA). A past Chairman of both the UKTFA and the Timber Research and Development Association (TRADA), Mr Mackay, said he was humbled to have been bestowed the MBE. Current UKTFA chairman, Geoff Arnold, commented: “Members of the UKTFA, both past and present, are incredibly proud that

ECOnetic
delivers affordable low CO2 technology n
Incorporating low CO2 technology, the new Ford Transit ECOnetic is based on the front-wheel drive Transit 280 panel van with short wheelbase and 2.2-litre 115PS Duratorq TDCi engine. Target fuel economy is 39.2mpg, while average CO2 emissions are a best in class 189 g/km. Following the launch of ECOnetic models in Ford’s Fiesta, Focus and Mondeo passenger car ranges, the company is now continuing this affordable low CO2 approach in the commercial vehicle market. In addition to the new Transit ECOnetic, an ECOnetic version of its compact workmate, the Fiesta Van, is also now on sale. Steve Kimber, commercial vehicles director, Ford of Britain, said: “We appreciate that our commercial vehicle customers have a clear interest in saving fuel and lowering their cost of ownership. At the same time, environmental friendliness is also growing in importance for them, and with the new Transit ECOnetic they can achieve both.” Available as an option, a closed-loop, coated Diesel Particulate Filter (cDPF) enables Transit ECOnetic to satisfy the Euro Stage V emissions standards. The 115PS engine reaches its peak power at 3,500rpm, and delivers a maximum torque figure of 300Nm at 1,800 to 2,000rpm. The Transit ECOnetic features the Durashift six-speed manual transmission (VMT-6). This offers a wider range of available gear ratios over the prior Durashift five-speed transmission, allowing better fuel economy

at all speeds, while the power and torque upgrade offers rewarding performance on demand. The ‘shorter’ gearing in first gear allows for improved pull-away performance, while the ‘longer’ gearing in top provides improved highway fuel economy (around 10 per cent better compared with the combined NEDC figures), with reduced engine revs for a range of speeds and loads for the standard Transit configuration. For the ECOnetic version, longer gearing has been achieved through the fitment of a 4.36 final drive ratio. Standard on the Transit ECOnetic is Ford’s Electronic Stability Program (ESP) system, including Hill Launch Assist (HLA). It also has a generous array of standard equipment, including the Ford Audio 6000 unit as well as load box safety equipment, including a full steel bulkhead and solid tie down hooks. Additional features, such as a trip computer (to monitor fuel performance), rear parking sensors and a new rear view camera with overhead seven-inch colour display, can also be ordered. The Transit ECOnetic is as practical as any Transit. It offers 1,097kg gross payload (the standard Transit 280S van is 1,092kg), and the same load box volume of 6.5 cubic metres – using the SAE method of volume calculations. Detail engineering for the Transit ECOnetic included reducing the availability of the heaviest options such as a second sliding door. However, all standard and optional safety and comfort features are available. q

Awards are a national ‘first’ for the house building sector The inaugural National House-Building Council (NHBC) Health & Safety awards, held in May this year, are the the house building sector’s first ever awards for health and safety on building sites.
n
The awards offer builders the opportunity to share best practice, showcase excellence and celebrate the great work of their health and safety teams. The awards have been a great success and the NHBC are delighted with the industry’s response to the scheme. The NHBC’s independent judging panel included Philip White, Chief Inspector for Construction at the Health and Safety Executive and Kevin Fear, Head of Health and Safety Strategy at Construction Skills. Every site was visited four times over a three month period and was scored against pre-set criteria covering items such as proactive management of risk, meeting the challenges of that particular site, robust management systems and physical risk control and workforce involvement. The top performing sites were then visited again, scores verified and the results presented to the independent judging panel. The panel ultimately selected the winning entries in each category. q

Orderly approach wins the day for Darren n
Darren Smith, National Winner of the Large Builder category, won the award for his work at Berkeley Homes’ Slade Park development in Oxford, a large site of student accommodation. Having worked in the industry for 26 years, 15 as a Site Manager, Darren particularly impressed the judges with how his ongoing ‘good order’ campaign has inspired his contractors to respect their work environment and how he has addressed the particular hazards of timberframe. Darren puts his success down to meticulous attention to detail in having the right measures in place to ensure safety for everyone on site. For example, having external stair towers as opposed to internal ladders for scaffolding, which is checked daily to ensure safety; fitting hard-wired temporary fire alarms in the building, having fire points on every floor; running a non-smoking site; not allowing electrical links within the building; installing temporary lighting to ensure that corridors are well-lit; erecting pedestrian barriers around the building and generally keeping the site tidy, are just some of the numerous safety precautions in
place on his site. “We are also quite strict as a company with regard to allowing only CSCS or affiliated card holders to work on the site, as well as running site induction training for operatives, in addition to holding regular toolbox talks and project meetings” he said. “Winning the award was good for me, good for the site team and good for the company”, added Gary, who said that he has received numerous letters of congratulation from the directors and managers of his company. The Slade Park development will provide accommodation 353 students at Oxford’s former Territorial Army barracks. The development comprises accommodation arranged in four blocks around a central courtyard on three and part four storeys. The scheme has been developed using high specification purpose-built factory constructed modular units having a predominantly brick façade with timber cladding and grey panels on the upper levels. The accommodation comprises 24 self contained studio rooms (2 accessible) and 350 single en-suite rooms arranged in a mix of
Darren Smith, National Winner of the Large Builder category four and six bedroom cluster flats, each having independent kitchen and lounge facilities. Communal facilities will include: a fully fitted communal area with seating and computer hot desks; a hotel lobby style front of house reception and access to the laundry facilities and a flat screen TV area. External facilities will include a good sized courtyard with hard and soft landscaping giving access to all blocks; 12 car parking spaces (2 disabled) for visitors and staff and 187 cycle spaces. The site has been designed to be secure and self contained with perimeter fencing and controlled access points for both pedestrians and vehicles. Berkeley will retain part of the site to build 72 other homes, including a selection of flats and town houses. q
Gary achieves a first for Ashleigh and for Scotland n
National Winner of the Medium Builder Category Gary Hines , site Manager at Ashleigh Scotland’s Marchfields development in Dumfries, says the secret of his success is in having a good site team behind him. “It really is a big team effort. Everybody on the site from labourers up to management level have co-operated, with everyone looking out for each other. Even the simplest things such as keeping the site tidy play an important role and everyone has helped with this. We were really pleased to initially achieve a Highly Commended Award, but to go on and win a regional and then a national award is unbelievable” said Gary, who has been in the building industry for over 30 years and has been a site manager with Ashleigh Scotland for seven years. A statement from Ashleigh Gary Hines receives his award
(Scotland) commended his success, saying: “This outstanding achievement is a reflection of Gary’s, and Ashleigh’s continual commitment to upholding the highest safety standards. Gary was first commended for his work and subsequently highly commended. He went on to win the regional awards for Scotland and the North of England, and has now won the full national award for the UK. Gary has now become the first employee of a Scottish company ever to win the award.” Marchfields is an expansive site comprising terraced, semi and detached houses as well as flats. The judges were especially impressed with how work at height was being managed, the universal use of stair towers in preference to ladders and the regular meetings Gary holds with trade contractors to discuss health and safety matters. q

Environment matters One of the topics under the spotlight in this issue is the thorny question of contaminated land - an environmental issue of some importance when you consider that the UK’s contaminated land sector is worth £1 billion a year, employs almost 8,000 people and is expected to grow by almost 3.5 per cent per year between now and 2015, with the number of jobs in the sector expected to increase to 10,000. Many people are now investing in the clean-up process of contaminated land to reclaim it, as development land is scarce. In addition, the Government is encouraging the clean-up of contaminated land by introducing an enhanced tax relief for the costs incurred by companies in cleaning up land they acquire in a contaminated state. With the ever-growing demand for water (and subsequent increases in cost), the known adverse impacts this can have on local environments, and new government regulation geared to reducing water consumption, the UK market demand for rainwater harvesting systems is on the increase - mirroring what has already taken place in other industrialised countries. Which is why this issue includes coverage of the increasingly important role of rainwater harvesting, including how Part-G of the Building Regulations, which came into force on 6th April 2010, introduced the concept of two water supplies in the home, namely ‘wholesome’ (ie mains) water for potable use, and ‘non-wholesome’ (from some other source) for non-potable applications such as toiletflushing, clothes-washing and the outside tap. Using non-wholesome water instead of mains water helps to meet the water efficiency requirements set out in the Building Regulations. The simplest and most cost-effective way of doing this is to use rainwater harvesting. Sustainable design is now an important element of many building projects nationwide, representing a rapidly growing market. Not only is sustainable design one of the Government’s key targets, it is also becoming an important requirement of construction clients. This issue takes a look at those who lead the way in the sustainable design stakes, with a round up of this year’s winners of the BREEAM (Building Research Establishment Environmental Assessment Method) Awards.

A powerful force within the contaminated land sector Picture courtesy of Ecologia
by CLIVE BOYLE, CRB Environmental Ltd - Vice Chair, EIC Contaminated Land Working Group
e
The UK’s contaminated land sector is worth £1 billion a year and employs almost 8,000 people. The industry is expected to grow by almost 3.5 per cent per year between now and 2015, with the number of jobs expected to increase to 10,000 over the same period. Despite these business and employment opportunities, current market conditions could drive development away from more complex and challenging brownfield sites, to what is perceived to be easier/cheaper greenfield plots. The industry faces real challenges, so effective representation, lobbying and other engagement with Government and regulators is more important than ever. Environmental Industries Commission (EIC) was launched in 1995 to provide the environmental technology and services sector with a strong and effective voice with Government in the debate about how to ensure that British companies succeed in a growing worldwide market. This is clearly demonstrated in the land remediation industry, where The Contaminated Land Working Group of EIC most effectively represents the interests of the sector, as well as providing a forum for information exchange and networking between professionals engaged in it. The work of the group and its members contributes to bringing derelict, blighted and contaminated sites back into beneficial use, reducing the risk to human health and the environment that exists from the contaminating legacy of former industrial and other activities and to sustainable development. The current interests and campaigns of the group and its members are best illustrated by looking at extracts from the Contaminated Land Remediation
Manifesto presented by EIC to all parties prior to the election and now being progressed with the Coalition Government.
A strategic approach to sustainable construction EIC welcomes the UK’s far-reaching commitment for all new homes to be zero carbon by 2016 and its ‘ambition’ for all new non-domestic buildings to be zero carbon by 2019, but believes that these policy objectives must been matched with an equally ambitious commitment to improve all aspects of sustainability in development. cont p9

Severn Trent Services receives MCERTS accreditation for waters analysis constructionnational
e
Severn Trent Services can now provide MCERTS accredited analysis for sampling and chemical testing of water. On 1st June 2010, Severn Trent Services, analytical services division was granted accreditation to 17025:2005 for the Environment Agency MCERTS Performance Standard for undertaking sampling and chemical testing of water (Version 1.1). This means they can provide a comprehensive accredited service for organisations required to carry out Operator Self Monitoring and provide analysis of sewage effluent, untreated sewage effluent and trade effluent for over 300 additional determinands at their Coventry, and recently opened, Wakefield laboratories. The Severn Trent Services sampling team were also granted accreditation to the same MCERTS performance standard for sampling untreated and treated sewage effluent at waste water treatment works and for on-site testing of these samples for PH and conductivity. The Environment Agency programme for gaining MCERT for Waters accreditation meant that, although Severn Trent Services were audited before end 2009, accreditation to MCERTS could not be granted to any organisation until June 1st 2010. Further information and detail on accredited determinands and schedules of accreditation can be accessed online on the UKAS website. n • Severn Trent Services, with global headquarters in Fort Washington, Pa., USA, is a leading supplier of water and wastewater treatment solutions. The company’s broad range of products and services is concentrated around disinfection, instrumentation and filtration technologies, and contract operating services.

Risk assessment of contaminated land There is an urgent requirement for legal limits to be set for land contamination which local authorities can use to define ‘unacceptable risk’ to human health or the environment from contaminated land and, therefore, the trigger point at which land must be remediated. These legal limits must be adopted in the Statutory Guidance for the Contaminated Land Regime under Part 2A of the Environmental Protection Act 1990 and through the planning process.
SiLC stands for specialist

Financing brownfield development The general economic problems faced by the land remediation sector are compounded by a £40 million extra tax burden the Government recently imposed through the replacement of Landfill Tax Exemption for contaminated soils with an extension of the Land Remediation Relief to include a broader range of costs on long term derelict sites. EIC fully supports the principle of incentivising a move away from landfill to treatment. However, it remains concerned that what the Government has introduced is not a tax neutral measure, as intended, but will result in a significant net flow of revenue to the Treasury out of the brownfield development sector. The impact of the Relief is also hindered by the inability of developers to claim the relief until the development has been sold. EIC believes that the Government should support the redevelopment of brownfield sites through the Land Remediation Relief by allowing developers to claim in year of spend; changing the definition of long term derelict; allowing Landfill Tax Exemption for asbestos, and allowing the transfer of the Landfill Tax Exemption.
With a vision statement ‘To develop, and maintain a high quality unifying qualification for the assessment of the condition and remediation of brownfield sites which fulfils the needs of public and private sectors and society as a whole,’ SiLC stands for Specialist in Land Condition. A registered Specialist in Land Condition (SiLC) is a senior practitioner/professional able to demonstrate a broad awareness, knowledge and understanding of land condition issues, who can give impartial and professional advice in their field of expertise. A SiLC is competent to verify the accuracy of a completed Land Condition Record (LCR). Initially designed to support the use of the LCR, launched by the Urban Task Force in 1999, SiLC is increasingly recognised by government and regeneration agencies as a much broader qualification. It is the only Professional Qualification of its type for experienced individuals working in Land Condition and the assessment of brownfield land. To be eligible to apply for SiLC registration, a candidate must be able to demonstrate a minimum of eight years of suitable work experience after graduation and hold membership of a professional body at an appropriate level. n
National framework for brownfield development EIC urges the Government to adopt a National Framework for Brownfield Development with criteria that should apply to development projects on brownfield land, covering: insurance, liability provisions in contractual terms, enforceable accredited testing, and appropriate competence demonstration for practitioners.. Full details of EIC and the group’s activities can be found at: www.eicuk.co.uk. n

Property-based flood
protection
solutions come of age e
Since its formation in April 2001, the Flood Protection Association (FPA) has played its part as the ‘voice of the flood protection industry’ as a key stakeholder and steering group member in helping shape the way forward for flood risk management. The final report by Sir Michael Pitt, which was published on 25th June 2008, recommended the templates and timetable for a pragmatic approach to tackle the growing problems that large-scale and localised flooding presented. Following the recommendations’ early adoption by all parties, the Flood and Water Management Bill was drafted, encapsulating much of the recommendations and timetable, and the Bill received Royal Assent on 8th April 2010. Following the election, the Department for Environment Food and Rural Affairs (Defra) and the Environment Agency (EA), are formulating the implementation of the Act to take account of the coalition’s objectives to achieve better value and encourage innovation. To meet these objectives, it seems logical to expect that the new strategy will at last lean heavily towards property-based solutions. They not only meet best value and innovation criteria, but can also protect against many of the different sources of flooding, whilst minimising displacement in not passing the flood consequences downstream. The responsibility for deployment and ongoing maintenance also passes to the property owners rather than remaining with the EA, therefore removing the continuing cost burden which results from other forms of communal flood defences. A move towards property-based solutions is also supported by the early success of the Defra Grants Scheme - for example the properties that were protected in Appleby have not suffered inundation in last year’s flood events. This builds upon the growing body of evidence of private properties having been successfully protected by kitemarked and engineered solutions in many flood events over past years, which has encouraged property owners to act on their own account. Temporary and demountable solutions provide protection to many thousands of properties across the length and breadth of the UK. Many have already proved effective following the floods (in 2004, 2005, 2007, 2008 and 2009) in Hereford, Bewdley, Ironbridge, Shrewsbury, Worcester and a number of other locations. This seed change has also resulted in some Insurers re-evaluating their approach to providing flood insurance at commercial rates, and excess for properties that have minimised flood risk by installing accepted property-based flood solutions. With the proven benefits that property-based systems can provide at much better value for money, there is, in the opinion of the FPA, no reason why they should not have much wider use in flood risk management. Property-based flood solutions have clearly come of age with Defra and the EA recognising their benefits and widening their use as an accepted part of their ‘toolkit’ in reducing flood risk and the consequences of flooding.

Water shortages –
rainwater
harvesting to the rescue … by LISA FARNSWORTH, Director, Stormsaver Ltd
e
With recent floods still fresh in the memory, it is hard to think of water as a scarce commodity - but the fact remains that water supplies throughout southern England remain under stress, seriously so in the highly populated south-east. Surprisingly, rainfall per head of population in the south of England is lower than in the countries surrounding the Mediterranean, again particularly highlighted in the south-east where population densities are highest and average rainfall is least. With population predicted to continue rising by a further 20-million over the next four decades, the water supply situation is predicted to deteriorate critically unless effective action is taken now.
Policies and regulations … This imperative has been reflected for some time by Government policy documents such as the Code for Sustainable Homes (CSH) and its counterpart for commercial buildings, BREEAM assessments. The Code includes important mandatory targets for reducing mains water consumption, initially by bringing current average usage of 150-litres per person per day down to 120-litres (CSH levels 1 and 2), then in progressive stages (105-litres for CSH levels 3 and 4) down to 80-litres (CSH levels 5 and 6). As a matter of policy, the Government is already committed to new houses funded by public money being built to CSH levels 3 and 4, becoming levels 5 and 6 within another two or three years. With the support of the house-building industry, it is also committed to progressively upgrading Building Regulations so that the private sector follows suit with all new houses being built to Code level 5 or 6 by 2016. This is reflected in the draft updated Part-G of Building Regulations which came into force on 6th April 2010. For the first time these introduced the concept of two water supplies in the home, namely ‘wholesome’ (ie mains) water for potable use, and ‘non-wholesome’ (from some other source) for non-potable applications such as toiletflushing, clothes-washing and the outside tap. The regulations go on to state the need for water efficiency and identify the maximum per capita consumption of mains water permissible.
Water substitution … Using non-wholesome water instead of mains water helps to meet the water efficiency requirements set out in Building Regulations. The simplest and most cost-effective way of doing this is to revert to the historic practice of harvesting rainwater, with modern systems being entirely automatic and for the user indistinguishable from using the mains supply. The installation of a modern rainwater harvesting system whilst a house is being built is very straightforward, with a storage tank being coupled to the normal guttering and down-pipes as part of the general drainage works. Separate pipework is also installed to serve the non-potable services so that at no time can the wholesome and non-wholesome supplies come into contact with each other. Given the right balance between roof size, local rainfall and house occupancy, a correctly sized system will provide most of the nonpotable water required by a household, thereby reducing mains consumption by up to 50%. In commercial premises and other
constructionnational environmentalbuildsummer summer 2010 2010 41 13
constructionnational
14 summer 2010 42 environmentalbuild constructionnational summer 2010
environmentalbuild constructionnational buildings used by the public, this saving rises to well in excess of 80% given a large roof and a high demand for non-potable water.
Impact on consumption ‌ Applied to meeting the water consumption requirements of the Code for Sustainable Homes (progressively being mirrored in Building Regulations), levels 1 and 2 of the Code (120-litres per person per day) can probably be met by simply using straightforward economising measures such as smaller toilet cisterns, dual-flush cisterns, aerated shower and tap heads, and use of water efficient clothes and dish washers. However, this needs to be demonstrated, using the official water consumption calculator, to the local planning authority before the house can be sold, so for even this basic requirement substituting harvested rainwater for mains water might be the clearer option. Levels 3 & 4 of the Code (105litres) become more problematical as the benefit of all the above measures has already been reaped, leaving bath size (or omission of the bath altogether) as the only remaining economising measure. Alternatively, use of harvested rainwater to reduce mains water consumption is likely to be a more popular option for most buyers of new homes. Getting down to the 80-litres per person per day required by CSH levels 5 and 6, realistically can only be achieved by substituting non-wholesome water for mains water using technology such as rainwater harvesting.
The big picture ‌ Around 8 million new homes need to be built over the next four decades which, if fitted with rainwater harvesting systems, could reduce reliance on mains supplies by around 40 cubic metres per year per property, or 320-million cubic metres collectively. To this needs to be added the potential for fitting/retro-fitting systems to suitable public buildings which could easily double this figure, thus meeting around 10% of the country’s total water needs.

Green roofs - now a major player in the built environment by DUSTY GEDGE, President of the European Federation of Green Roof Associations, Director of Livingroofs.org Ltd and lead consultant with www.greenroofconsultancy.com
e
There is a growing recognition, both nationally and internationally, that our approach to the built environment requires a re-assessment. Increasingly green infrastructure within the urban realm will, and to some extent is, being seen as a major player in this realignment. The second World Green Roof Congress [WGRC] in London provides a unique opportunity for professionals within the built environment to witness the latest developments in this field, whether it is the development of city-wide policies, the latest implementation techniques or detailed research on how green roofs and walls perform within the sustainability agenda. Green roofs are often dismissed, primarily because they do not score as high on the energy and carbon dioxide emissions as some would like. The congress will highlight how green roof technology is one of the few technologies that provide a range of benefits. This has started to be recognized at policy level throughout the world, from Portland, Oregon in the USA to Tokyo in Japan. In the UK, London has been at the forefront of advancing the green roof agenda. The Greater London Authorities’ (GLA) green roof and wall policy has been in place since March 2008. During the period of 2004 – 2008 we know that over 450,000m2 of green roofs were installed in the capital. It is likely that at the WGRC this September, the latest figures will be available to demonstrate how the policy is having an effect. Planning has an important role to play in mainstreaming green roofs in the UK. Whilst there is a need for clear codes of practice for green roofs, which will be addressed at the congress, planning authorities have an important role in ensuring that the quality of green roof implementation is embedded in conditions. With hotter summers and the likelihood of increased intensive summer storms predicted as a consequence of climate change, green roofs have a distinct role to help ameliorate these effects and the congress is fortunate to have a number of recognised authorities on these issues.
Green roofs and ecosystem services are now part of the built environment agenda. However a full understanding of the range of benefits and how these benefits relate to one another needs to be understood by all involved in designing, project managing and delivering buildings within the built environment. The congress offers the only chance to engage with a range of independent authorities from around the globe and many UK suppliers. The WGRC takes place on 15-16 September 2010 in London.

A leading authority on e
Geared to promoting green roof development and implementation through research, education, demonstration, information and technology transfer, is the University of Sheffield’s National Centre of Excellence for Green Roofs. Part of the Department of Landscape, the centre is the leading research establishment for green roofs in the UK, with research being undertaken in several different departments. The current green roof activities in Sheffield originated through small research programmes carried out at the University of Sheffield in 1999 by Dr Nigel Dunnett, now Director of the Green Roof Centre and Reader at the University of Sheffield’s Department of Landscape, Since then, research activity has increased dramatically, Sheffield City Council has become very active in policy development

and promotion of green roofs. Groundwork Sheffield has become a powerful green roof advocate, and the city now contains a number of landmark green roof projects including Sharrow School, Jessop West and Sheffield Cathedral, to name a few.
Green Roof Code of Best Practice 2009-2012 In 2007 Groundwork Sheffield and Green Roof Centre staff began preparing a bid for the European Commission LIFE+ fund, to develop a UK code of best practice for green roof installation. Currently there are no UKspecific standards, which means there is an over-reliance on European standards which are not in tune with the UK climate. The bid was successful and work started on the Green Roof Code in early 2009. The Green Roof Code will be disseminated throughout 2011. n
Landscape experts secure two major projects
e
Frosts Landscape Construction Ltd is a company who are specialists in a number of markets. Traditional hard & soft landscape schemes on the ground have been their main market since the early 1970’s, however they have installed many green roofs over this period, the first being some 25 years ago. Since carrying out the award winning detail design and installation of the green roof for the GCHQ building in Cheltenham 2004, the company has played a major part in installing some of the largest and most technical projects in the UK. So they are pleased to announce the award of two major roof garden projects, Neo Bankside and the new Parkway shopping Centre in Newbury, with a combined value of £4.5m. Securing such work is based on the client’s confidence in the Landscaping Contractor to carry out all the detail design and deliver on time at the right quality, and a proven track record puts Frosts in a strong position. At the recent BALI Awards no fewer than four awards were collected, three of which were for roof gardens (see BALI article in this issue). Vizion in Milton Keynes was a 7500m2 roof terrace above a large supermarket; and two awards for the Ropemaker project in Moorgate London, on which the judges commented: “The degree of difficulty presented by this project has to be seen to be believed. The contractor was given a concept to turn into reality. It was a privilege to see the reality created by experts in their field.” n Frosts look forward to growing the Green Roof and Living Wall business to new heights…

Showcasing excellence - BREEAM
award
winners take a bow e
Showcasing excellence in sustainable design, the BREEAM Awards recognise and reward those involved in the design and construction of the highest scoring buildings certified under BREEAM (Building Research Establishment Environmental Assessment Method). A BREEAM Excellent rating is a pre-qualification, so the winners truly represent the best in the industry. The awards are not subjective, as each development has been independently assessed and certified. In order to win an award, each building must have excelled in every environmental category within BREEAM (eg from Energy to Ecology) and therefore winners represent a holistic approach to delivering environmental sustainability. Amongst the 2010 award winners are Bletchley Leisure centre in the BREEAM Bespoke Category and Salisbury Law Courts in the Courts Category.
Bletchley Leisure Centre The new Bletchley Leisure Centre for Milton Keynes Council includes a 25 m competition pool, four squash courts, sports hall, health and fitness suite, dance studio, cafĂŠ, indoor bowling facilities and multipurpose function rooms. Under the BREEAM assessment, the building scored well through:

The voice of authority for the...
e
RenewableUK is the trade and professional body for the UK wind and marine renewables industries. The association was formed in 1978 and has 619 corporate members. Wind has been the world's fastest growing renewable energy source for the last seven years, and this trend is expected to continue with falling costs of wind energy and the urgent international need to tackle CO2 emissions to prevent climate change. In 2004, RenewableUK expanded its mission to champion wave and tidal energy and use the association's experience to guide these technologies along the same path to commercialisation. The association’s primary purpose is to act as a source of information for its members and to promote the use of wind, wave and tidal power in and around the UK, acting as a lobbying group to highlight the benefits of wind energy and marine renewables to government, industry, the media and the public. RenewableUK research and find solutions to current issues and generally act as the forum for the UK wind, wave and tidal industry, and have an annual turnover of over four million pounds. n

Renewable UK is the newly adopted name of what was the British Wind Energy Association (BWEA). Speaking of this change, which took place in March 2010, Adam Bruce, the organisation’s Chairman and Global Head of Corporate Affairs at Mainstream Renewable Power said: “This development
is essential to aid us in implementing our vision to be the voice of authority for the renewable power sector and a credible source of information and knowledge for our members, the industry, Government, media and the public. “By 2040, when we celebrate the 30th anniversary of RenewableUK, it is very

A groundbreaking report comparing North Sea offshore energy potential with the region's oil and gas production was welcomed by RenewableUK. Published by The Offshore Valuation Group, a coalition of government and industry organisations, the report, entitled The Offshore Valuation suggests that using less than a third of the total available offshore resource could: generate the electricity equivalent of 1 billion barrels of oil annually, matching North Sea oil and gas production; create 145,000 new jobs in this country and provide the Treasury with £28 billion in tax receipts; enable Britain to become a net exporter of electricity by 2050 and reduce carbon emissions relative to 1990 levels by 30%. n
likely that we will be living in a different world, the seeds of which will have been sown by the work of BWEA: a world of decarbonised energy generation, electric vehicles and offshore installations and grids spanning the continent of Europe. We aim to be at the forefront of this revolution.” n
Extensions to offshore zones prove sector strength
e
A recent announcement by The Crown Estate on extending Round 1 and Round 2 offshore wind farm sites has been endorsed by RenewableUK as further evidence of the viability and strength of the UK’s pioneering offshore wind programme. The Crown Estate awarded an additional 2GW of sites, sufficient to power 1.4 million homes on an annual basis, to seven existing offshore wind farms. Peter Madigan, RenewableUK’s Head of Offshore Renewables, said: “The extensions of Round 1 and 2 sites follow on the heels of successful commissioning and operation of seven wind farms over the last four to five years. The announcement is entirely driven by developer interest and provides emphatic evidence of offshore wind viability and growth. The projects are proven to deliver, so it makes sense to scale them up.” Out of the seven sites involved, five will be granted an extension of project area, while two will have more capacity added within the existing project boundaries. n

Changing
Landscapes e
Recent times are seeing a shift in perspective; the economic and political landscapes have added a slant to the already uncertain future the country faces. In parallel to this, the change from traditional to renewable and sustainable heat and power has customers across the country caught in limbo with their heads spinning, trying to unravel and predict the best options. Often, driven by achieving targets in energy efficiency, reducing fuel poverty and carbon emissions, there can be a conflict of interest between the various objectives. With the removal of the Low Carbon Building Program (LCBP) grant structure and the delay in publishing the Renewable Heat Incentive (RHI) scheme, the market is seeing a switch from heat to power for energy savings – Wind Turbines and Photo Voltaic (PV) being at the forefront, with demand often outstripping supply. The main challenge facing the industry is that of credibility in the face of these demands. Too often we are seeing knee-jerk reactions to requests, where inefficient and inappropriate systems are being fitted. Domestic and General Insulation Limited, as other reputable companies, believe this is not in the best long term interests of clients or the industry. Around the country we are seeing panels appearing on roofs where the aspect offers little efficiency, heat pumps configured that produce either too little heat or where the efficiency and outputs are compromised in order to provide the required heat. In addition, solar thermal systems of single panel east/west that produce little or no useable hot water. Many parameters are ignored in favour of giving exaggerated and fanciful figures to bamboozle clients. In particular, PV arrays
where yields are exaggerated and the Feed in Tariff (FIT) inaccurately forecasted. It is quite surprising the amount of customers who either ignore or do not understand the Standard Assessment Procedure (SAP) rating and the implications of not insulating the property before installing heating or energy systems. What is even more surprising is the number of companies prepared to follow such instruction? With the majority of homes getting insulated by conventional means, external insulation is a viable proposition for the ‘hard to treat’ buildings and should be foremost in improving the SAP rating of a building. To overcome and prevail we must resist the short term gain of installing such unsuitable systems and offer robust advice and real solutions based around the individual needs of properties, client and customer (the latter often being ignored). There is a basket of exciting and brilliant solutions that we can bring to clients, where assessing their needs and giving them detailed and concise information, unbiased by a preferred manufacturer, will ensure development and growth It is widely known that gas and oil will run out in our life time, and as that dates nears, the increased cost will make today’s fuel prices fade into insignificance. New initiatives such as green loans and grant funding must be looked at, and Government lobbied for the medium to long term. The UK is at the forefront on climate change, we now need to take the necessary steps required to provide sustainable efficient technology. n by Steve Belfield, Heat and Energy manager Domestic and General Insulation Limited

Biomass energy sector powers ahead
e
The biomass energy sector has experienced considerable growth over the last few years, reflecting increasing fossil fuel prices and ambitious, legally binding targets for reducing greenhouse gas emissions. The Biomass Energy Centre (BEC) was set up in April 2006, as a technical advisory service for the biomass industry and has answered several thousand enquires, the majority of which related to wood fired heating systems.
Boilers
Fuels
Wood chip boilers Wood chip boilers are available in a wide range of sizes, from those suitable for a single house, up to industrial devices capable of running large district heating schemes. Equipment is available designed to burn most kinds of wood chip, but it is important to identify the type of fuel you expect to use at the outset, as this will affect the system you need.
Wood pellets Pellets are a processed, clean, consistent form of woodfuel that flows easily, burns efficiently and is pleasant to handle. Wood pellets are made by compressing dry sawdust under very high pressure, giving a high energy density, which minimises the space required for storage. Pellets are also the most expensive form of woodfuel, close to, or even slightly more than the cost of mains gas, though usually significantly cheaper than oil, electricity or LPG. Logs and briquettes Logs are at the opposite end of the woodfuel spectrum from pellets. They are not so consistent or dense, usually require manual loading into the boiler, and tend to be dusty. They are, however, significantly cheaper than pellets and represent a fuel that is easy to find from local suppliers (or produce from your own garden). Briquettes are effectively large pellets made from compressed sawdust. They can be burned in log stoves and offer greater heat output per cubic metre than logs, but at significantly higher cost. Wood chips Wood chips are the lowest energy density form of woodfuel. While the cost and space required for this tends to be beyond the scope of most domestic installations, chip can represent a very cost effective, low carbon option for larger buildings, and businesses with sufficient storage space.
Pellet boilers Pellet boilers are well established technology in many European countries, offering reliable operation for many years. Systems are now available in the UK in a range of sizes from very small domestic devices for energy efficient houses, up to systems suitable for large buildings or district heating schemes. Installed coal boilers can also be converted to run on wood pellets.
Log Boilers Modern, batch type log boilers also offer very high efficiency, which they achieve by burning logs in batches in a high temperature environment, storing the energy as high temperature hot water in a highly insulated accumulator tank. This heat is then supplied to the central heating and hot water circuits.
Stoves Traditional stoves are available that run on either logs or pellets to provide radiant heat to the room. They need to be manually fed with fuel as required to maintain the heat output, and achieve significantly lower efficiency than boilers.
Smoke control areas Biomass fuels are not approved for use in smoke control areas, except in officially approved ‘exempt appliances.’ The website www. uksmokecontrolareas.co.uk gives lists of Smoke Control Areas and approved appliances. n

Demolition
fights back
e
The UK demolition industry has suffered more than its fair share of economic blows during the past 12-18 months - but under the stewardship of President David Darsey, the National Federation of Demolition Contractors has continued to invest in readiness for a longawaited upturn. Having inherited the NFDC presidency just as the demolition industry dipped into recession, David Darsey is now well into the second 12 months of his two-year tenure in the federation hot seat. Darsey’s personal passion is improving welfare and health monitoring for demolition workers. But his single-minded NFDC President David Darsey pursuit of this objective has been balanced by one defining obstacle that has shaped the first half of his presidency; one that has informed every plan, strategy and decision: the challenges of a failing economy.
Darsey and the federation has also put its financial muscle behind an initiative to help those rendered unemployed by the industry-wide downturn. The federation was instrumental in the creation of www. demolition-jobs.co.uk, an industry recruitment website that effectively works in reverse. “By using the website, unemployed demolition professionals can advertise their availability to work free of charge. The site can be browsed free of charge by potential employers seeking qualified workers,” Darsey explains.
Exacting standards
Through no fault of his own or of the industry he serves, Darsey has been presiding over an industry suffering its worst recession in memory. At the time of Darsey’s election, the true extent of the impending recession was still not known, particularly to the banks and financial institutions that caused it. Demolition work had certainly slowed in many parts of the UK, and many NFDC members had already started to take evasive action: trimming equipment fleets; stretching out non timereliant contracts to keep men and their remaining machines in action; and ultimately reducing workforces. But the joint promise of a pre-London 2012 Olympic spending spree coupled with the hope of additional work demolishing buildings rendered economically unviable by the Government’s reduction in rates relief on empty buildings, seemed likely to see Darsey’s chosen industry through.
In addition to inheriting the presidency at a time of economic downturn, Darsey has also become the first to be required to enforce the Federation’s Accredited Site Audit Scheme (ASAS). The scheme, in which NFDC corporate members must submit sites for inspection by an independent third-party to ensure that they are upholding the exacting standards demanded by the NFDC, became a pre-requisite of membership when Darsey took up the hot-seat. Darsey has more reason for optimism than just increased website traffic. Together with former NFDC presidents David Keane and John Wring and NFDC CEO Howard Button, Darsey has just cemented the federation’s membership with the UK Contractors Group “We are delighted to have been accepted as members of the UKCG as it allows us to meet with some of the largest and most influential main contractors in the country,” Darsey says. “Our ultimate aim, of course, is to reach a point where all main contractors use only NFDC members.” One year on, Darsey was faced with the unenviable task of expelling members that had failed to adhere to the strict conditions of the ASAS scheme. “Unpalatable as this is, there is little point in having an accreditation scheme that is not enforced”, says Darsey.

Looking ahead
During the past 12 months, the federation has lost several corporate members to the recession, almost all to a new-found, risk-averse attitude within the banking sector; the very same banking sector bailed out with public money just a few months earlier. But under Darsey’s stewardship, the National Federation of Demolition Contractors has acted swiftly and incisively, investing heavily to make itself stronger, more able to weather the economic storm raging all about it.
With more than a year of NFDC presidency under his belt and just under a year of his tenure remaining, Darsey is already looking ahead to what, he believes, is a brighter future for his chosen industry. “There are huge swathes of the UK’s city centre buildings that will need to be demolished to help the country meet its carbon reduction targets. And it is likely that business rates will increase still further as local authorities seek to make up shortfalls in funding from central Government,” David Darsey concludes. “This should signal an increase in demolition activity right across the UK, providing NFDC members with some welcome relief from the two years of doom and gloom they’ve been forced to endure.” n
Impact of recession
Ongoing investment Despite the recession, the NFDC invested around £1 million to relocate from its longstanding but increasingly cramped headquarters in Staines, Middlesex to a new facility in Hemel Hempstead that would provide it with greater administrative space and allow the federation to readopt the National Demolition Training Group (NDTG) and pursue its aims to create a competent, carded workforce.

Construction site dust control and the law
e
Nuisance dust emissions from construction and demolition works are common, with fine particles from these sources capable of being carried long distances from sites, polluting the local environment and affecting the health of local residents, as well as those working on the site. In addition to legal health and safety requirements, further regulations now require local authorities to work towards achieving national air quality objectives and construction site operators will therefore need to demonstrate that both nuisance dust and fine particle emissions from their sites are adequately controlled and are within acceptable limits. With this in mind, DustScan Ltd was recently commissioned by VolkerFitzpatrick Ltd to prepare a dust management and monitoring strategy (DMS) for site redevelopment works at East Parkside, Greenwich. The works are being undertaken for Meridian Delta Ltd (the overall site developer) and comprise reconstruction and provision of infrastructure prior to development of individual plots on a brown field site on Greenwich Peninsula. The DMS was prepared after consultation with Greenwich Council’s Environmental Protection team and follows construction industry best practice guidance and Greenwich Council’s own Noise and Dust Protocols.
Fugitive ‘nuisance’ dust emissions are monitored at five locations on the site boundary using DustScan DS-100 directional dust gauges. The DS-100 is a passive (i.e. unpowered) dust sampler, featuring a ‘sticky cylinder’ to sample dust in flux for subsequent quantification. The directional dust monitoring head collects fugitive dust from 360° around the gauge to indicate potential dust sources and pathways. As recommended by DustScan Ltd, directional dust samples are taken over seven day intervals. At the end of the monitoring intervals, each sampling cylinder is removed and placed in a protective carrying flask and a replacement head fitted. Used sampling heads are sent to DustScan Ltd for computer analysis. Directional dust is reported at 15° resolution as Absolute Area Coverage (AAC%, the presence of dust irrespective of colour) and Effective Area Coverage (EAC%, the darkness or potential soiling of dust). The dust monitoring results are tabulated and shown as ‘directional dust roses’ to show the magnitude of AAC% at each monitoring location for each sampling interval. The directional dust monitoring data can be reviewed in accordance with the London BPG for ‘sticky pad’ dust monitoring and are summarised in relation to the DustScan AAC% and EAC% ‘dust nuisance risk matrix’. To assess the risk of fugitive dust from the site affecting nearby residents, directional ‘arcs of significance’ were determined for the site as ‘any direction where dust propagation might cross the site boundary’. For this, the dust data is summarised as a ‘risk factor’ of potential dust nuisance across the site boundary in five levels ranging from ‘very low’ to ‘very high’. Ongoing dust suppression measures are revised and updated according to site conditions and operations. n
