Welcome. . .

What a month it has been for Great Britain’s sporting heroes! As I watched in awe at the achievement of all the athletes, I couldn’t help but take in the outstanding facilities that have made this possible. The construction of each and every venue has not only produced momentous moments for the nation, but has acted as a catalyst for economic growth and has helped to kick start a multitude of sporting events.

But what can be done to sustain this? With public sector budgets taking a severe hit over the coming months, according to a recent Constructionline survey, further new build public sector leisure facilities are admittedly out of reach. Last month, the UK Government Certification Service revealed that one in four public sector clients are likely to cancel construction projects over the next six months and additionally find ways to cut back on procurement costs.

However, as the saying goes, a little goes a long way. Improving facilities and public spaces is by far a great place to start and is made possible by a host of accessible building solutions. Browsing through this issue of PSBJ, you will find plenty of companies demonstrating their affordable, high impact products designed to offer functional and cosmetic improvements – from seating and sports surfacing, through to changing facilities and play equipment. Who knows, you could soon be providing refurbished facilities for our next generation of sporting champions!

Denne to deliver new affordable homes Denne, part of the Leadbitter Group, has won two contracts to design and build affordable homes in Maidstone, Kent, on behalf of Golding Homes Housing Association.

The first scheme, on Church Street in central Maidstone, will start this summer and is due to finish in late Autumn 2013. It will involve the construction of a single timber frame block of 26 apartments, built to meet

Code for Sustainable Homes level 3. The second project, Finch Court on Dickens Road, which is north of the town centre, is due to begin later this year with the demolition of the existing flats on the site. These will be replaced with 20 three-bedroom houses built to meet Code for Sustainable Homes level 4, which will be available for social rent.

Graham Brown, Managing Director

of Denne, says: “The start of the Church Street scheme marks the beginning of what we hope will be a long and mutually beneficial relationship with Golding Homes. We are proud to be delivering these much needed affordable and sustainable homes to the people of Maidstone.”

H&S research identifies key preventatives

Sixth Form project to maintain high school standard Senior pupils at Bolton School will soon be enjoying a new common room, cafe, study spaces and outdoor areas thanks to a new Sixth Form Centre, designed by architects Cassidy + Ashton. Pupils will be able to access the three-storey building by glazed corridors which connect it to the existing premises. Lawrence McBurney, Cassidy + Ashton’s lead architect on the project says: “It has been a pleasure to work with Bolton School to create something which will become so prominent at this already very striking school.

The opportunity to introduce a new

building within the main quad, adding and complementing the setting of the listed buildings has been a challenge but one which we think has created a unique and dramatic centrepiece for the school.” Bolton School is regarded as one of the leading educational establishments in the North West and is a significant historical landmark on a key gateway into Bolton town centre.

The original Bolton School buildings were the result of an architectural competition in the 1900s and governors were keen to ensure that new buildings follow the same high standard of design.

Innovative communication techniques that helped to prevent worker deaths during the Olympic build could be harnessed to benefit other construction projects – a research study has found. From the findings, IOSH highlights five key areas which can be used in construction companies and projects of all sizes.

These are: lead from the top – the ODA set standards and also visibly engaged with the workforce; develop competent supervisors – the positive impact of technically knowledgeable supervisors upon health and safety was understood; foster an open, positive safety culture – if workers are engaged and feel managers care for their wellbeing, they’re more likely to get involved with the health and safety process; reward good behavior – in many cases positive feedback was the real reward, as it boosted morale; and review and learn.

Any problems were constantly reviewed and communicated across the organisation.

Wernick completes £12m deal with funding from RBS Essex-based Wernick Group (Holdings), the modular and portable building manufacturer, has expanded its business with the purchase of 3400 cabins funded by a £12m financing package from The Royal Bank of Scotland’s (RBS) Midlands Structured Finance Corporates Team.The term loan and asset finance package agreed with

RBS has allowed Wernick to significantly expand its stock of over 30,000 units.

The purchase has been made from Kier, the construction, services and property group, with whom Wernick have entered into a supply agreement to provide ongoing availability of the assets.

Wernick Group has experienced strong organic and acquisition-led growth over

the past 10 years supported by RBS, with whom the Group has banked since its inception. This latest acquisition follows the successful acquisition in July 2011 of Rovacabin, a national cabin hire business with a hire fleet of nearly 4000 cabins and Eventlink, a provider of temporary stadia seating to the events industry.

Isle of Wight joins standardised schools revolution Willmott Dixon and Scape’s solution to cut the cost of building new schools by up to 50% has attracted another local authority client with the Isle of Wight Council investing approximately £9m in its Sunesis standardised product.

Sunesis is Willmott Dixon and Scape’s brand for a new generation of predesigned primary and secondary schools available at a fixed price that aim to achieve a build cost per pupil

of £8500 to £10,000 against a typical school cost per pupil range of £15,000 to £20,000. Isle of Wight is to invest in the Keynes model for Gatten and Lake Primary School in Shanklin, which comes with a large flexible learning zone and a range of optional extras such as an internal sliding wall, play equipment, furniture and a canopy. The council will also invest in a Dewey model for The Bay CE Primary School in Sandown, which

is currently going through the statutory planning permission process. Dewey is ideal for a more restricted site, and efficient use of space includes a roof top playground. John Frankiewicz, CEO for Willmott Dixon Capital Works says: “It’s great news that the Isle of Wight will use Sunesis to provide new homes for two schools. The schools will combine a well designed, quality product with high energy efficiency in operation.”

Carbon control The boiler suit at Guy's Hospital, designed by Heatherwick Studios, covers the combined heat and power system

Richard Rugg, Managing Director of Public Sector Advice at The Carbon Trust, reveals the benefits and opportunities that can be gained from implementing carbon management programmes. With a number of new public sector organisations already on board and taking action, significant improvements are a testament to this scheme.

I

n an era where the need for austerity and cuts are frequently discussed, opportunities can often be overlooked.

The case for the public sector to invest in comprehensive carbon management programmes is compelling, especially as fuel and electricity prices have risen steeply in recent years. Cutting carbon and energy bills can liberate budgets which can be allocated to delivering services. In over 10 years of working with the public sector the Carbon Trust has already helped to save over 17 million tonnes of CO2 and £600m, but there are still a lot more savings to be made.

The scale of the opportunity is staggering. The public sector is responsible for up to 23 million tonnes of CO2 emissions annually, which carry

8

Public Sector Build Journal

an associated energy cost of around £5b. Capital investment of just £1.5b, spent on the most cost effective solutions, could result in £500m of annual savings, providing payback in as little as three years.

Public sector action Although the public sector is taking the lead nationally when it comes to making an impact on emissions, there is a lag between recognising the opportunity and taking action. Recent Carbon Trust research shows that over 80% of the public sector agrees that carbon reduction projects will deliver financial benefits, but that only 58% were planning on making tangible investments in carbon reduction in

2012. However this is still a significantly higher percentage than those intending to take action than in business (46%) and the voluntary sector (33%).

With just 37% of public sector organisations feeling like current government policy supports their carbon reduction activities, the internal financial and reputational business case for action is crucial. By taking the initiative and investing in cutting energy consumption, public bodies can use cost savings to deliver more efficient services and ultimately deliver greater value for the public.

This has been recognised recently by the Committee on Climate Change in their report on how local authorities can reduce emissions and manage

Upfront climate risk. They highlighted that there is a significant risk that sufficiently ambitious plans will not be developed and implemented. This is all the more important because the report also recognised how great an influence local authorities can have over the indirect emissions in their areas, particularly in buildings, surface transport and waste – sectors that make up 40% of the total greenhouse gas emissions in the UK.

Initiating leadership

For those starting out there is a carbon management programme which has been developed and refined since 2006, starting with basic measurement and ending with a five-year strategy to put into practice.

To reinvigorate and extend the ambition of organisations that have already taken action on their emissions there is a carbon management

revisited programme. Finally for those that want help in best practice with the intricacies of implementation, financing, procurement and embedding sustainability within an organisation there is a new collaborative implementation programme.

This year 24 public sector organisations are taking part in the Carbon Trust’s three carbon management programmes.

Participants come from local authorities, the NHS, further and higher education institutions, central government departments and executive agencies.

They range from the Environment Agency and Kent Police, through to Bradford Teaching Hospitals and the British Museum. All are demonstrating impressive leadership by investing in taking action on their own carbon footprints, and saving themselves money by cutting energy bills.

The three programmes being run are designed to suit organisations at different stages on their carbon journey.

tools and support for measuring their current emissions, forecasting their future emissions, and setting realistic targets and actions for reducing these. This involves identifying projects, and making the financial business case for savings, as well as engaging staff, management, and stakeholders with their opportunity to have an influence on emissions.

Plenty can be achieved through low or no-cost actions, just through looking at optimising existing facilities and changing organisational behaviour. One of the biggest opportunities for savings

in many buildings is reducing the cost of heating. Immediate impacts can be made just through simple actions such as encouraging staff to close windows and doors, moving furniture that obstructs radiators or vents, and setting the right temperature in buildings. Proper maintenance of boilers alone can save up to 10% on annual heating costs.

Relatively cheap measures, such as installing lighting and heating controls to ensure equipment is switched off when not needed, can provide swift returns on investment, typically less than three

years. Larger invest-to-save measures, such as installing LED lighting, can also deliver large savings, with the additional benefit of lower maintenance costs because the lamps have longer lifetimes.

These small changes often have the benefit of not just saving money but making workplaces more comfortable.

There are a variety of more ambitious measures, which include recladding inefficient buildings from the 1960s and 70s or installing renewable heat and electricity technologies, such as biomass boilers, solar panels or wind turbines.

Strategic investments As an example of what can be achieved, Guy’s and St Thomas’ NHS Foundation Trust were one of the first public bodies to start working with the Carbon Trust back in 2006 on the carbon management programme. Over their first three years they achieved 20% reductions in annual emissions, which was double the NHS target for the same period. The Carbon Trust helped them to develop a strategy, business case and projects to achieve this. The most significant investment was in new combined heat and power engines at each site, which delivered savings of around £1.5m and 11,000 tonnes of CO2 a year. This year they will be taking their commitment even further by taking part in the inaugural collaborative implementation programme.

Just starting their journey are organisations such as Hull College. With 27,000 students they to make sure

that their environmental credentials can match their academic performance, which is ranked Grade 1 – Outstanding

by Ofsted. Other organisations taking part this year include Lincolnshire County Council, revisiting carbon management in order to reinforce and extend the outcomes from their first five year carbon management plan.

With an investment of £1m they managed to achieve ongoing annual savings of £350,000.

There are a number of benefits for public sector bodies by taking part in programmes at the same time alongside their peers. Of course the costs to individual organisations are significantly reduced through the oneto-many approach, but it goes beyond this. Organisations have the opportunity to share their concerns, explain how they overcame hiccups and setbacks,

develop an understanding of best practice, and inspire each other with their enthusiasm and ambition.

By investing in carbon management organisations will not only see the financial and carbon benefits for their own organisation, but are able to show leadership in their sector and local communities. It is important for the public sector to take an opportunistic approach to the savings that they can make, which will drive more sustainable and efficient public services in the long term. A little of this entrepreneurial spirit not only frees up money to spend on vital public services, it also helps support the UK green economy, and reduce the very real risks from climate change. In other words, everybody wins.

■

There are even long term investment opportunities with decentralised energy or combined heat and power. The solutions vary significantly between estates. For example it is significantly more difficult to improve building fabric in listed properties, or in buildings with large catering facilities then heat recovery can be used from the kitchens to preheat hot water. Although there are a number of options when it comes to energy efficiency, the Carbon Trust is able to use 10 years of experience to help public sector organisations to carefully evaluate the cost-effectiveness of projects before making decisions.

Housing

Dual development Six of the newly-built apartments will be made available for teenage parents, with on-site facilities including an IT suite, a nursery and indoor play space, and a garden and play area

In a bid to provide communities in Kent with enhanced affordable housing opportunities, Golding Homes, in partnership with construction firm, Osborne, has delivered two sustainable housing developments. The seamless integration of sustainability was, in part, thanks to Osborne's sister company, InnovarĂŠ, who demonstrated how off-site processes do not have to compromise coordination and efficiency.

T

wo former council sites in Maidstone in Kent have been transformed into a 131 home strong housing development following the completion of a ÂŁ12.8m project.

Spread across two sites which were previously home to a Park & Ride car park and a council depot, the development at Armstrong and Enterprise Road was built in a period of 16 months by family-owned construction, civil engineering and property services firm Osborne for their client, affordable housing provider Golding Homes.

The new development is a mix of affordable and market-priced homes consisting of flats and houses. The first site in Armstrong Road is made up of 96 homes, including two- and threestorey terraced housing and a fourstorey block of flats. The second site in Enterprise Road consists of 35 homes, with a mix of two- and three-storey housing and a three-storey block of flats.

30 of the new homes are available for sale, shared ownership and private rental; the remaining 101 homes are

14 Public Sector Build Journal

available for affordable rent. All of the new homes are built to very high quality standards and to a striking contemporary design. Following an agreement with Maidstone Borough Council, the new homes will be offered for affordable rent to home-seeking

families who meet a set criteria.

Housing to stay in the housing for up to two years and after this they will be helped to move into independent accommodation in Maidstone.

Sustainability has been a key feature of the design of the new properties.

All the buildings have been fitted with photovoltaic cells, water butts, composters, productive planting beds and communal bin stores, which has helped the development achieve a Code for Sustainable Homes (CSH) Level 4. As part of their level 4 Code for Sustainable Homes accreditation, the properties have to achieve a Dwelling Emission Rate (DER) 44% higher than the Target Emission Rate (TER).

All of the properties meet the standard for Lifetime Homes, increasing the adaptability and sustainability of each unit. The homes achieve +5db enhancements over building regulations for sound testing and an air leakage of 3m3/m2/hr. The superior insulation levels, air-tightness and minimal cold-bridging will help the dwellings achieve an estimated 48% reduction in annual fuel costs.

seeing the long term benefits of using structurally insulated panels, and senior members of the Golding Homes team even paid a visit to Innovaré’s factory in Coventry to gain a better understanding of the panels and the process behind

All of the properties meet the standard for Lifetime Homes, increasing the adaptability and sustainability of each unit. The homes achieve +5db enhancements over building regulations for sound testing and an air leakage of 3m3/m2/hr.

t

Leading structural insulated panel systems provider Innovaré Systems was appointed to design, build and install i-SIPs panels to both sites. Made under factory controlled conditions, i-SIPs panels are manufactured to fit bespoke building designs. The i-SIP panels also offer a range of applications from full structure, that include internal walls, floors and roofs, to i-SIP panels for infill and/or cladding to high rise steel or concrete frame construction.

The panels used on the Armstrong and Enterprise Road sites were manufactured off-site and then installed

by Innovaré. As a result of the change to using i-SIPS panels, the project team were able to rely on a quick, predictable build programme, lower post construction snagging (which resulted in a better quality product) and a higher thermal performance.

Golding Homes recognised the benefit of the chain of custody available through Innovaré and Osborne being part of the same group. Keen to adopt off-site construction techniques, Golding had been interested in

Public Sector Build Journal 15

Housing

for medium as well as small scale developments. The on-site construction of the new homes using our i-SIPs panels took just 16 weeks to complete, with over 10,000m² of 162mm i-SIP panels for the construction of the external walls, 17,500m² of internal Open Panel Timber Frame partitions, 8000m² of intermediate floor cassettes and over 5000m² of trussed roof joists.

“The fact that we were brought on board early in the project’s life meant we were able to grasp what was required of us early on and get a really strong understanding of the objectives

16 Public Sector Build Journal

of this project. Because of the close collaboration between ourselves, Golding Homes and Osborne, we were able to quickly identify and implement the most cost effective and timely method of off-site construction available which meant we were able to comfortably meet the deadlines on the project.”

Complex construction Stephen Scard, Business Unit Leader for Osborne’s Homes team, adds: “Any development of this size and location presents a set of challenges, but this

project had an additional complexity to it because the development was spread across two sites.

“As a result, we needed to adopt a coordinated approach to minimise disruption to the local area, and ensure that all the residents were kept up to date of what was going on. By working with Innovaré and using i-SIPs panels we were able to significantly cut build times and deliver these properties to Golding Homes in a much shorter timeframe without compromising on the quality or environmental efficiency of the finished buildings.

“These new properties will be home to a wide range of people in an area which really needs new homes. These buildings have been designed to be environmentally efficient without hindering comfort or aesthetics and hopefully will be real homes to the people who live in them.”

Golding Homes’ Director of Development and Regeneration Chris Blundell comments: “We are pleased to see residents moving into these much-needed new homes. We have taken great care in the design and construction of these homes and look forward to seeing a thriving community developing here.”

Talking Point

By unlocking information on existing day-to-day usage, it is possible to reduce the amount of energy that is wasted across the operation - in turn releasing valuable budget which could be spent elsewhere

Taking control New research shows public sector workers are growing increasingly concerned about the potential impact of rising energy bills. Here, Jon Kent, founder of Zeco Energy, explains the motivation for creating a sophisticated new software application and how it can help organisations to manage and reduce waste.

W

ith the continued squeeze on budgets being felt across the public sector, as many as 61% of professionals are worried about the impact of rising energy costs on their organisations, according to the results of a recent OnePoll survey.

The research, which gathered the views of 195 UK public sector workers, underlines the need to do more to tackle avoidable waste and reduce the financial burden of rising operational expenditure.

Yet the fact that typically, bills reflect the entire building’s energy usage means that even those businesses conducting analysis on consumption or tracking fluctuating prices have little opportunity to really understand where and how the energy is being wasted.

As a result, it is also difficult to implement the necessary organisationwide behaviour change required to achieve meaningful energy and cost savings.

18 Public Sector Build Journal

The most common challenge faced by those with responsibility for energy management is that the data produced from bill validation, tariff analysis and building management systems is complex and difficult to understand.

For this reason, the ability to enable users to turn energy data into usable information was the principal motivation for creating Zeco Energy Manager, which was specifically designed to empower business users by highlighting exactly where and how much data is being wasted

Greater visibility Rather than being technology-driven, the energy management solution serves as business-user applications, making it easy for anyone in the organisation to use and visualise usage. The intuitive tool converts consumption data into financial data, which in turn enables accountability

by department and even individual team members.

Armed with this information, it is also possible for the energy champion, be they a facilities manager, finance manager or a board level director, to incentivise staff based on a target level of savings over a set period.

Data on the amount of energy and budget saved can be translated into meaningful financial savings for the organisation, releasing enough capital to buy new equipment or employ new staff when budgets are tight.

The fact that the Zeco Energy Manager solution is based on a wireless mesh network means it can be used to enhance any existing building management system, enabling portable monitoring beyond the main/ sub-meter. Crucially, the software leverages and optimises the existing infrastructure, while the web-based technology, telemetry and open

Talking Point

Empowering effective action Energy management technology is particularly worthwhile for organisations with buildings that generate annual energy costs of over £20,000, where savings of between 10 and 20% on future bills can easily be made and a 12- to 18-month return on investment achieved.

For some organisations, the

immediate visibility the technology brings has shown to help highlight costly usage patterns which had previously gone unnoticed. Obvious areas for improvement are heating and ventilation, lights, temperature control and equipment or lights being left on out of hours or when not in use.

One office-based user, for example, had been heating their building at a constant 23 degrees both day and night – and at weekends. Identifying that the building management system had been set incorrectly will reduce their future bill by 30%.

Similarly, by running its air conditioning system 24hrs a day, energy management software showed a leisure centre to be running at 50% of its day time consumption during the night, without realising this could be reduced to just 15% by ensuring, for example, that the air conditioning is only on when needed.

Here too, the necessary changes will yield a decrease of 30% on future bills.

Advanced energy management technology really comes into its own when managing multiple sites.

Previously, for instance, one public sector user who was responsible for managing energy across 65 schools had to either visit each site or obtain the relevant information from their energy bills. Now, he is able to access information about the best and worst performers while on the move. As a result, he can now concentrate his workload on specific schools and identify the particular areas requiring most attention.

Worthwhile savings

Jon Kent is managing director and founder of Zeco Energy, with a proven sales and commercial track record in the business software industry. Zeco is the realisation of Jon’s vision to enable businesses to easily identify and reduce energy waste to make business savings.

The bottom line is that, however well-intended corporate awareness schemes are, without clear information about when and where energy is being used within the organisation it is difficult to reward or incentivise staff.

For this reason, accurate usage data is essential for managing effective change.

Perhaps the most compelling aspect of the Zeco Energy Manager software is that it automatically generates easyto-browse reports for all relevant line managers, which contain headline

Energy management in the public sector - research snapshot •

The OnePoll research showed that responsibility for monitoring energy in the public sector tends to fall to office managers (22%); facilities managers (24%); financial controllers (19%) and energy managers or champions (18%).

As many as 12% assign no accountability for energy management.

•

30% of public sector organisations rely on energy bills to track energy usage, 18% use a building management system, 10% say they use analytics technology to break down their usage, while a further 19% use an energy monitor. 11% are unsure if and how energy is monitored and tracked.

Significantly, more than four in 10 professionals believed greater visibility of energy usage within specific areas of the organisation would help them to reduce energy costs. Almost half (49%) also identified the ability to assign budgets to defined KPIs as being a key driver for essential behaviour change.

information and results. As such, it doesn’t require a lot of input from the business or users but will serve to highlight waste when it occurs, enabling the user to identify the necessary steps required to reduce it immediately.

By unlocking information on existing day-to-day usage, it is possible to reduce the amount of energy that is wasted across the operation – in turn releasing valuable budget which could be spent elsewhere. This ability to act on waste, rather than identifying it retrospectively when the bill comes in, is fundamental for generating measurable, long-term carbon and cost savings.

■

communication protocols it relies on essentially makes it is a scalable ‘plug and play’ solution, similar to a smartphone or tablet app.

The energy management tool also provides the means with which to implement control, as well as providing users with remote visibility. A director or facilities manager can use a smartphone or tablet to find out their organisation’s energy costs while on the move. In addition, when combined with easy-to-fit energy management hardware, users can also switch off areas of the business that are using energy such as lights and other equipment automatically outside of normal business hours and can also operate equipment remotely by using a mobile application for the iPhone or iPad.

Security

Secure from the start

Justin Freeman, technical manager for the UK's biggest locksmithing trade association, the Master Locksmiths Association, looks at the security issues which need to be taken into account when designing, building and developing a public facility.

T

perimeter security is built into the original design. Access to the premises should ideally be limited to one or two main routes, with strong gates and perhaps an electronic entry system for parking areas.

Lighting is also important – dusk-todawn lighting can act both as a deterrent to night-time intruders and an aid to identifying any suspicious individuals.

Lighting above main exit doors can also be particularly useful in helping people entering and leaving the building during the dark winter months.

Thorough assessment An expert can also give you advice on the various types of CCTV available and can verify whether a system complies with current regulations and is the most appropriate solution for the development.

The ability to monitor exactly who is coming in and out of a public building is essential for ensuring security and meeting health and safety regulations.

A development-specific security plan is advisable. Access control includes locks and keys, electronic systems, digital entry systems and even manned receptions.

Most users of a public facility – staff and visitors alike – will gain access via a manned reception, which is important both for monitoring who is entering the building and creating a welcoming impression.

It’s nevertheless important to ensure that you have key-based and/ or electronic entry systems in place to safeguard the premises 24 hours a day. Keys are useful for protecting outbuildings and main entrances/exits to the building, as well as controlling access to areas of the building internally through master-key systems, for instance to ensure confidential data is protected.

It’s advisable to invest in a patented system whereby keys can’t be copied without providing proof of ownership.

If a key goes missing, it can be deleted from the database, the lock reconfigured and a new key issued to ensure there are no rogue keys in circulation.

In emergency situations the primary focus has to be easy egress – security is secondary to the much more important element of helping people get out of a building quickly and easily. An expert locksmith will be able to advise on where emergency exits should be positioned, the signposting required, advisable height levels for escape handles and the number of exits needed for the size of a building. They would also be able to specify what locking systems/security can be fitted to these exits.

Ultimately, it is always advisable to speak to a qualified, vetted and inspected locksmith to discuss security solutions that best meet the particular needs and use of the facility, so you can plan appropriate security measures into the design right from the start.

■

he conflicting demands faced by architects, contractors and developers mean that security often has to compete with other priorities. However, I cannot emphasise enough how vital it is that security is taken into account right from the outset.

The perimeter of your planned facility needs to be fully protected by appropriate security measures. With public buildings it’s important that they appear aesthetically welcoming, so security features have to be carefully designed so as not dominate the overall impression.

Get a security expert to come out and walk round the external site with you.

They will be able to advise on how you can create a strong boundary which will keep intruders out without making the facility look unwelcoming. Whether your project is a leisure centre, school, hospital or other public facility, it will act as a hub within the community and it’s important that the building appears accessible while safeguarding those who use the premises.

Wherever possible we advise that

Education 17,500m² redevelopment project and worked with Atkins, project manager and quantity surveyor Faithful+Gould, and the Council to bring the design within the £32m budget.

The redevelopment was broken down into four main phases beginning with the refurbishment of the grade ll listed sixth form building. Here the challenge for the design team was to blend the architectural heritage of a previous century with the needs of a modern education environment.

Renowned landmark

Windows of opportunity Sustainability was a prime consideration on the BREEAM Very Good project

It was fitting that the opening of Richmond School in North Yorkshire

by Lord Coe coincided with the arrival of the Olympic torch. The event marked the completion of a four-year construction project that has resulted in a flagship education facility for the county.

T

he opening represented the completion of a £32m project overseen by North Yorkshire County Council that has provided a fully-extended school and 21st century facilities for students across all curriculum areas and with outstanding out-of-hours amenities.

Back in 2006 the Council was successful in bidding for a DfES grant under the ‘Building Schools for the Future’ programme for the redevelopment of the school. The new design by Atkins overcame the difficulties that arose from the school being divided

between two sites one mile apart by integrating all facilities on the Darlington Road site. This became a prime factor in the successful grant application together with the inclusion of sustainable features in the radical design.

The project also re-modelled the existing campus – which contained a range of buildings reflecting different architectural styles over the last 70 years – so that the new sections would complement the older facilities and preserve the school’s identity.

Shepherd Construction was appointed as main contractor on the

The building, originally designed in the 1930s by acclaimed architect Denis Clarke Hall, had become a landmark and accommodated only teaching spaces. The team worked closely with English Heritage to preserve striking features such as the blue ceramic tiled corridor known as the ‘River of Life’ and the beautiful curved staircase and then revamp the existing spaces to provide a modern environment for the 450 students.

Building work on the new sixth form centre was completed in July 2009 and created a welcoming new entrance, classrooms and dedicated facilities such as a bistro, internet café, common room, quiet study area and a new dance studio formed by infilling a courtyard area to complement the school’s creative arts specialist status.

The later phases concentrated on the construction of the new main school buildings, comprising a new linear block and glazed link block that connected the refurbished existing middle school building and the new six-court sports hall and fitness centre to provide much-needed coherence to the overall school layout. This was one of the main objectives of the design brief to enable a much more efficient use of the teaching space and to simplify the movement of pupils and staff within the school campus.

In addition to this, the existing Library block was refurbished and structurally altered to form a new design technology department For Shepherd Construction one of the main challenges was working in a ‘live’ school environment, as Colin Sargeant, Shepherd Construction’s regional

At ground level the fenestration also features a series of unusual stone cairns reflecting the local stonework tradition, which have been in-filled with curtain wall. The overall effect has been to give the building the appearance that the upper levels are supported by, and almost floating on the stone cairns.

managing director explains: “With the whole of the site being redeveloped we had to carefully plan a phased sequence of works to keep disruption to a minimum and ensure the safety and welfare of pupils and staff was a priority at all times.

“An extremely robust level of communication with the school was maintained to schedule in and prevent any impact to the running of the school, for instance when exams were taking place. We also carried out specific elements of the external infrastructure works within the boundaries of the school outside normal working hours and other works were also programmed to be completed during holiday periods.”

The high level of consideration was noted by the Considerate Constructor’s scheme assessor who commented: “This is an exceptionally considerate site.

The development of the school creates a highly complex challenge for the site’s management and their achievements are exemplary. Meticulous planning and communication is minimising the impact of the works on academic life.”

The project was awarded two bronze and one silver national award in the Considerate Constructor’s Scheme.

The striking new linear building houses the specialist science, music, art and ICT facilities as well as the library and administrative hub. The building has been finished at first and second floor levels with high performance render and

The Middle School, after a complete facelift and modernisation programme, accommodates the teaching spaces for English, Maths, Languages as well as the learning support departments.

A six-court sports hall and fitness centre was also created with extensive landscaping of the external spaces to provide much-improved sports facilities.

After four years, construction was completed 10 weeks ahead of schedule and has provided a state-of-the-art school for the 1700 students as well as facilities, such as the sports hall, that the whole community can make use of.

Shaded glass and multiple electric car recharging points are just some of the environmentally-friendly highlights of The Quadrant:MK. In addition, the building has extensive ‘living roofs’, which will encourage diverse habitats for floara and fauna in the centre of the city, and a rainwater harvesting system will be used to flush toilets and irrigate landscaping. When it came to selecting a manufacturer who would provide similarly sustainable and energyefficient heating systems to ensure minimal impact on the environment, Jaga was the natural choice.

Over 1.25km of Jaga’s Mini Canal trench heating system, designed to be installed into a duct and easily concealed flush with the surrounding floor, were installed throughout The Quadrant:MK – directly adjacent to the large glass panels that feature on all of the building’s floors. The placement of the Mini Canals prevents condensation on the glass panels and neutralises unwanted draughts from outside, ensuring the building’s many occupants are able to work in comfort at all times.

The Mini Canal uses Jaga’s Low-H2O technology – a low-mass, low-water content system, equipped with an efficient fin tube element that complies with present and future building codes.

The super-light, ultra-thin sheets of aluminium and copper – 181 fins per metre of radiator – react faster when warmth is needed, meaning the Mini Canal consumes less energy and cuts carbon-emissions by 10%.

In turn, this helps to ensure The Quadrant:MK’s sustainability, offering maximum performance with minimal fuel consumption.

Slim and discreetly designed, the Mini Canal comes in a staggering 588 dimensions, 21 grille models and 32 colours to blends into every interior. Special designs are also

available including angles, curves and special adaptations for pipe work and electrical trunking.

The Mini Canal is available in depths starting from just 90 to 500mm making it ideal for providing supplementary or primary heating across multiple storeys or floating floors. All Mini Canal products are delivered fully-assembled and ready to install.

Features include: rapid heating up speed due to the low water content; high heat output is achieved with normal and low flow temperatures; Low-H20 heat exchanger, which is made from copper and aluminium that is noncorrosive; and a 30 year guarantee.

Mini Canal grilles are available in a wide range of materials and colours.

Thanks to the low water content and high coefficient of heat conduction for low flow temperatures, Mini Canal with its Low-H2O element is ideal to use in combination with high efficiency boilers and/or condensing technology.

The Mini Canals were delivered to The Quadrant:MK fully-assembled, pre-tested and ready-to-fit for ease of installation. The trench has various depth and size options, and its versatility proved essential for this project, due to the 500mm excess void on each level. Jaga was able to adapt to this larger than usual depth, manufacturing bespoke ‘top-hat’ feet that raised the lengths of Mini Canal to the appropriate height. To match the stylishly modern interior of The Quadrant:MK, an aluminium rigid grille was used – elegantly hiding the innovative and ecofriendly technology beneath.

Airedale Hospital, West Yorkshire, has recently benefited from Durapipe's HTA to help combat bacteria growth

Cure in the pipeline Des Dolan, Brand Manager for Durapipe Building Services, discusses how to help prevent Legionella infections from building services systems. Whilst maintaining healthy pipes is critical, specifying the right pipework is the first step.

L

egionnaires disease has hit the news headlines recently after a severe outbreak in Edinburgh affected over 80 people, followed by seven people being struck down with the disease in Stoke-on-Trent. This has caused companies up and down the country to assess their systems to ensure they are operating safely.

Legionnaires disease is caused by a bacterium, Legionella, that has always existed in water and remains inert at temperatures below 25°C. It proliferates in water circuits at temperatures fluctuating between 25°C and 45°C, meaning sanitary hot water and air conditioning circuits are most at risk from contamination.

Legionnaires disease is caused by inhalation and cannot be contracted from ingestion. Infection occurs when water mists containing Legionella bacteria are inhaled. These water mists can occur anywhere where water is taken from pipework systems, with showers, cooling towers, spas, high-

pressure washers and humidifiers being among the most high-risk systems to spread the disease.

These pipework systems can be a major carrier of Legionella bacteria within buildings, therefore it is crucial that steps are taken to prevent growth of this bacteria within the pipe network.

Careful selection There are a variety of factors that can assist the potential for bacteria growth including stagnant water, dead volumes/ loops and temperatures from 25°C to 45°C. Within pipework systems, the Legionella bacteria develops and fixes in the presence of high concentrations of lime, magnesium, metallic residues and sludge, usually originating from corrosion and scaling. Within hot water and air conditioning circuits, bacteria can develop in pipework systems that are ageing, badly maintained, corroded and scaled.

While it is important that pipework systems are regularly maintained to

ensure system safety, the initial product selection can also impact on the longterm health of the pipes. Durapipe UK is advising that some materials are more likely to assist bacteria growth than others so careful consideration should be given to pipework selection at the outset of a project.

Bacteria settle and develop in biofilm, which easily attaches itself to sharp or jagged parts of a pipe’s surface, whether due to the quality of the extrusion of the new pipe, or to the corrosion/scale build up inside the used pipe, so a rougher surface will provide a stronger platform upon which to grow. This is due to the fact that rough surfaces have more surface area for bacterial attachment and growth and also provide more shielding from flow.

The smoothness of the selected pipework is therefore an important factor to consider; while the surface of some metallic pipes is rough, the smooth bore of plastic pipes ensures the ability for bacteria growth is limited. While copper

shock however and while C-PVC systems have exceptional resistance to chlorine, an ABS system would not be suitable for this method.

While preventative measures are effective, Durapipe UK is advising that to ensure pipe safety as far as possible over the lifetime of a system, it is important to incorporate this alongside other considerations.

The correct design and pipework material is the first area that needs addressing, once this is installed it is then vital to apply preventative measures on a continuous basis and undertake regular and thorough maintenance, sampling, cleaning and treatment. Ensuring there is no water stagnation and allowing good water circulation throughout the system is then an important ongoing check.

By their very nature plastic pipework systems, such as Durapipe’s HTA,

can help combat bacteria growth; the material characteristics offer corrosion and limescale resistant properties, resulting in a smooth bore which can limit and slow the growth process. In addition to its performance capabilities, Durapipe HTA also offers installation benefits. Its lightweight nature, combined with its quick and simple cold weld jointing technique, eliminates the need for hot works or skilled welders, further reducing the installation cost and time of projects.

Reduce the risk If specifiers or consultants are looking for guidance regarding the safety of pipework, regulations and guidelines regarding Legionalla in water applications are constantly evolving.

However, the HSE (Health and Safety Executive) has published HSC L8 (2000) Control of Legionella bacteria in waters. This is the approved Code of Practice and Guidance for the control of Legionella bacteria in water systems, setting out the statutory requirement for dealing with that risk and applies to all premises with a water system.

Proliferation of Legionella bacteria in water networks can become a major health risk, with 6000 cases of Legionnaires disease diagnosed in Europe every year. The industry needs to be assessing the safety of current systems and carefully considering new specifications to ensure they meet the approved regulations and offer a safe and healthy solution over the lifetime of the system.

has natural anti-microbial properties, as limescale builds on the used, corroded pipe surface, the biofilms then cling to the limescale and begin to colonise.

Once pipework systems are installed, it is good practice to protect chilled water and heating systems from biofilm development and the resulting bacteria growth by undertaking regular flushing and treatment processes from the outset. There are many effective methods that can be used to kill bacteria in pipework systems including flushing through systems, thermal shock and chlorine shock.

Flushing Flushing will limit bio-film thickness in water systems; shear forces caused by flushing will remove bio-film which extends out into the turbulent flow in the centre of a pipe. Plastic pipework should always be flushed out in accordance with BS5955 part 8.

Thermal Shock To work effectively, a temperature of 70°C must be reached and maintained throughout the entire pipework system over a period of at least 10 minutes, as Legionella bacteria dies above 60°C. This solution is the most natural and is very effective for circuits in good condition.

Chlorine Shock Another proven successful method is water disinfection.

Undertake circuit chlorination by filling pipework and tanks with a chlorine mix at a concentration of 15mg per litre of cold water for 24 hours, or 50mg per litre for 12 hours, followed by draining and thorough rinsing of all pipework.

Not all pipework is suitable for chlorine

Architectural journalist Gideon Sykes looks at how building access solutions can be adapted to suit the diverse needs and requirements of the public and staff.

O

ne of the problems of building access across the public sector is the varying needs and demands from different types of building.

Access into schools, for example, is quite different from access into hospitals.

Although the fundamental principles remain the same, the different needs mean that there is no one-size-fits-all solution to controlling building access and optimising levels of security.

The education sector is one of the most challenging. Parents and teachers rightly rate safety of children as their paramount concern. At each stage of their schooling and development, children and students need a safe and secure environment in which to grow, develop and to be inspired, but at each stage the inherent risks and dangers change.

A good example of how access and security can work in harmony can be seen at the University of West England campus in Bristol. Here, the University draws on the latest and best practice in terms of accessibility, security and sustainability.

The University required solutions

that would protect both the students’ personal security and their property.

Apart from conforming to the latest regulations, it was also important to make savings in operating costs and to enhance the overall security of the campus accommodation. To do this, Ingersoll Rand Security Technologies was commissioned to provide a fully coordinated package of products and services that would meet the detailed brief, protect the students and secure all the different areas.

The University of West England campus in Bristol draws on best practice in terms of accessibility, security and sustainability.

Building access becomes more complicated in healthcare environments because security needs can vary greatly according to the diverse functions of different areas. Sometimes access needs to work both ways. For example, a mental health and psychiatric hospital in the West Midlands has recently been refurbished with new access control systems to control visitor access from the outside, to restrict patient access to the outside and yet will allow the free flow of people if the fire alarm rings. To satisfy this complicated brief a clever mix of automatic doors and biometric entry systems has been put in place.

Here, Dor-O-Matic automatic slide and swing doors were installed inside the hospital entrance together with a set of manual doors connected to the fire alarm system, programmed to ‘swing-free’ when the alarm is activated. Controlling the reception area and out-patients waiting room, the doors were installed to provide double sided security both to prevent patients from leaving and to stop unauthorised visitors from gaining access. The system was also designed on the double door principle – requiring entrance and exit through two sets of doors working in parallel, where one door only opens when the other one is closed. This not only enhances security but helps to retain heat within the

High performance doors The solution was to install electronic locking systems on doors to the selfcontained apartment units which house about 2000 students. In addition, the facilities incorporate 100 Dor-O-Matic low energy automatic door operators to provide ease of access for disabled students. This high performance product can be fitted to inward and outward opening doorsets and can easily be retrofitted to existing manual doors, which helps facilities managers meet their obligations to provide access for all.

Many external, reception and internal doors can be linked to biometric access control readers

building and thereby conserve energy.

To provide further security, many of the external, reception and internal doors are linked to biometric access control readers using both fingerprint and proximity card readers. This makes entry for authorised staff quick and easy and negates the need for manual visual verification. The combination of both card and biometrics provides additional security over standard swipe cards by preventing access should a card be lost or stolen. Other sensitive areas inside the hospital, such as the Secure Ward, Administration and Management Suites, are also secured with biometric access control. The whole system is integrated and can be linked in to a time and attendance, staff scheduling and visitor logging system with the minimum of disruption and cost.

Many UK healthcare facilities still rely on traditional mechanical key systems which can prove difficult to control and expensive to maintain. Unable to afford the expense of hard-wired electronic access control systems until recently they have not had many other options open to them. However there are now a number of intelligent locking systems

34 Public Sector Build Journal

available which are inexpensive to install and easy to operate.

Flexible functionality PegaSys, for example, is the latest in wireless intelligent access control. This system provides an instant and cost effective way to upgrade and convert traditional mechanical doors into an electronically-controlled access system.

This is an easy to manage system aimed at establishments which are unable to spend a lot of money but seek to improve safety by being able to control and monitor who has access to the premises and when. Importantly, the system overcomes the cost and inconvenience of having to replace existing doors. It provides many of the benefits of a networked hard-wired access control system in terms of function, flexibility, control and security but at a fraction of the cost.

A typical example of PegaSys in action is Annonay hospital in France. This large hospital has over 1500 staff and caters for about 500 patients, offering a wide range of facilities including a nursing school. With five buildings and over 1000 doors, all the existing locks and cylinders

have been retained and the current system can expand as needs change and the infrastructure grows.

In theory, PegaSys could be expanded to cover up to 65,000 doors. It has the advantage of being retrospectively compatible with many existing technologies. This means that sites which already have applications such as Mifare Classic or Legic can be easily adapted to provide staff with one card, which can provide many different functions, such as ID, work area key, canteen and vending payment and PC access. It is designed to provide a simple solution to common access control and key management problems, such as replacing cylinders when keys are lost, unauthorised key duplication and the inability to track who went where and when.

The entry level system is simple and easy to programme, using stand alone off-line electronic locks to provide secure access control. As the locks are completely independent they can be fitted across multiple doors and multiple sites with no restrictions. To increase the functionality of the system up to four online controllers can be added, each capable of controlling four validation readers, fitted to the building’s initial entrance and exit points. These readers are used to download an individual’s access rights for that day to their card, enabling them to access only the parts of the building they are authorised to enter. This makes the system very flexible meaning it can be easily and cost effectively upgraded to meet the changing needs of the facility.

Community spirit The facility serves to act as a vital sports hub for local schools, clubs and community groups

The recently developed Hackney Marshes South Marsh Community Hub in Hackney, which has been recognised at the 2012 Civic Trust Awards, and has won a 2012 RIBA award, is playing its part in driving down carbon emissions.

D

esigned by architects Stanton Williams, in conjunction with Zisman Bowyer & Partners LLP consulting engineers, South Marsh Community Hub provides 26 new changing facilities serving players using the surrounding 60 football pitches as well as a multi-purpose community area

including offices and a café and bar.

The development of the South Marshes Community Hub forms part of the wider 2012-related regeneration and environmental improvement of the Marshes. The new facilities will provide a first class venue for schools, clubs and other semi-professional organisations.

ZBP was appointed by London Borough of Hackney following a selection and interview process to design the building services systems to a brief which included requirements to achieve low energy and CO2 emissions, while still meeting the operational requirement of the building and within a set budget.

The building services installation incorporates water saving features, as well as a number of energy and CO2 saving elements, which have allowed the building to achieve a very low EPC rating of 8 (A rated).

The energy saving elements include: high efficiency multiple bio diesel boilers for domestic hot water and space heating; heat recovery from toilet and shower mechanical ventilation systems; natural ventilation to first floor rooms via passive roof ventilators; zoning of the building allowing ventilation to areas not in use to be switched off; and water restrictors to control flows from sanitary appliances and showers.

Rainwater is also captured and stored and used to flush toilets thereby reducing the quantity of processed, drinking quality water required by the building. In the event of low rainfall mains water can be used.

The building location and pattern of use posed a number of challenges to the designers in respect of achieving an affordable, low CO2 solution. In order to meet these challenges a number of options were considered: Ground source heat pumps – the ground in the vicinity of the building is not suitable for use with ground source heat pumps as it contains rubble from WWII bomb damage and possibly contains buried unexploded ordnance, so this option was rejected.

Photovoltaic solar panels and solar thermal hot water were also considered but rejected due to concerns over vandalism and the large quantity of panels needed to meet the needs of the building thermal loads.

Combined heat and power (CHP) was rejected as the pattern of use did not allow sufficient concurrent use of thermal and electrical energy to allow a reasonable payback Wind power was also rejected due to concerns over performance, appearance, noise and planning difficulties.

Due to the distance from the nearest gas main of adequate capacity, a new gas supply would have been very costly so the decision was taken to fuel the boilers on biodiesel. The advantage of this was that the largest component of building energy use could be provided by a fuel having a very low CO2 emission.

The fuel used is B100 WVO produced from 100% reclaimed waste vegetable

oil with no addition of conventional fossil diesel. This is not produced from a crop grown specifically for fuel use and has a CO2 emission factor of 0.025.

The fuel is stored in a tank within the building which allows operation for 2-4 weeks between refills according to use.

The quantity of fuel that can be stored is limited as biodiesel has a relatively short “shelf life” and will degrade over time.

Other energy and CO2 saving measures include recovery of heat from shower and toilet ventilation where heat from the exhaust air stream is used to preheat fresh air being brought in.

Passive roof ventilators are provided to public and teaching areas of the first floor where wind and temperature driven natural ventilation is used to ventilate and provide a degree of summer cooling in these areas without use of electricity to drive fans.

Despite the challenges faced by the teams designing and building the South Marsh Community Hub, the project has proved successful – players, spectators and visitors have found the additional amenities provided by the Hub to be very user-friendly. Perhaps the success of this project will encourage local authorities to further pursue leisure projects where sustainability and the reduction of carbon emissions are vital to the brief.

be heated and stored prior to each showering event. Three boilers and one standby are installed allowing boiler capacity to be matched to changing load and maintaining capacity should one boiler fail.

In the summer season and during the week the usage is lower and not all changing rooms are needed so facilities exist for turning off ventilation to groups of changing rooms.

The pattern of use of the building, the major part of which is changing rooms, is intermittent but intense when in use. Typically on a weekend during the football season the changing rooms will be used by teams who play their matches and then all return to the changing rooms at once, requiring hot and cold water to be provided to 120 shower heads simultaneously for a period of 15-20 minutes.

Teams will then leave and be replaced by a second batch of teams who return to the changing rooms 2 hours later after their matches, requiring another 15-20 minute session of showering.

The energy required to heat these quantities of water is considerable and it was determined that the most cost effective solution would be to provide high efficiency boilers with large hot water storage vessels allowing sufficient quantities of hot water to

Temporary Buildings

A two-storey building can be seen from further away so a single-storey structure could be a better solution in planning terms, depending on the building's location

Avoid planning pitfalls Do you need planning permission for a temporary building? In this article, Robert Snook, Director and General Manager of Portakabin Hire, offers some practical advice by addressing some of the common misconceptions.

I

n the UK, the planning system controls the use of land and what is built on it, helping to achieve the balance between the need for property development and protecting our environment.

There is a clear misconception that temporary buildings do not require planning permission. This could be due to a lack of awareness, insufficient training for managers responsible for procuring temporary buildings, or

suppliers just not being clear – but planning requirements state that regardless of size, any building or structure in place over a 28-day period has to have planning approval.

There are some dispensations, for example for some domestic structures and for construction site accommodation, but the general rule is that all temporary and permanent buildings need planning permission if they will be in place for more than 28 days.

If planning permission is not sought, an enforcement order could be placed by the local authority to remove the building with immediate effect.

Planning approval can be sought retrospectively but we would never advise that.

Every planning application is different, some are more complex than others, and local policy will vary region to region. However, we would always advise having professional input to help ensure every project goes to plan and the building installation is not delayed.

An architect or planning agent can be appointed to manage the process or a

good modular supplier should have a dedicated department who can obtain planning approval on your behalf.

Portakabin has a dedicated team in place to manage the planning approvals process for our clients if they require it – and we have a 98% success rate, which we believe is unprecedented in the modular sector.

The UK planning system can be time intensive and specialist experience is essential. Make sure your modular building supplier has the resources to help if required, so delays to your project are avoided and that you are correctly advised and represented to prevent any future issues.

Minimum impact For every application, the planning officer will be looking to minimise impact of the building or structure on the surrounding area and on neighbouring properties. This means that approval for a temporary building in an industrial area, for example, will be easier to obtain than for a similar facility in a residential area.

Temporary Buildings

Planning Preparations 1. Assess the planning requirement. Check with your local authority exactly what planning permission is needed for the work you wish to carry out. You can also submit your application online using the Government’s planning portal – www.planningportal.gov.uk.

Facilities may be required to blend in more closely with the surrounding environment

classroom block is being refurbished’.

That way the planners know there is a finite end to the use of the temporary building.

Whilst modular buildings have improved radically over the years and now provide genuinely clean, modern and attractive accommodation solutions – internally and externally – there is still an understandable degree of reservation that a temporary building won’t remain on site for many years to come. Reassure the planning authorities that the building really is an interim solution.

And if you end up needing the building for a longer hire period, you can re-apply for planning permission at that time, in which case the planners will inspect the building and see how it is looking before they will grant an extension.

■

A two-storey building can be seen from further away so a single-storey structure could be a better solution in planning terms, again depending on the building’s location.

The hire period could also make a difference to the conditions imposed on your project. A building which will be in place for six months is likely to have much less stringent conditions applied to it than for a facility in use for five or 10 years. The latter may be required to blend in more closely with the surrounding environment and may need to be clad, for example.

In the application, be specific about the purpose of a building, provide as much information, and be as clear as possible about the timeframe. Rather than simply requesting permission for a temporary building, it is better to say, for example, that ‘Decant teaching accommodation is required for a 12-month period while our existing

www.portanews.co.uk

2. Which type of planning permission do you need? Define whether you need outline or full planning approval.

3. Consider professional input.

A good modular building supplier should have the resources to write, submit and manage your application for you.

4. Are Building Regulations a consideration? The Building Control department of the council will need to check that your building proposal complies with all relevant Building Regulations.

5. Draw up plans and proposals.

Plans for simple projects can be drawn up by a draughtsperson.

Plans for more complex buildings should be prepared by an architect or qualified engineer.

6. Research your application.

Prepare answers and solutions to the issues planners are likely to look for.

7. What should you include with the planning application? When the application is submitted, make sure the following are in place: Scaled drawings, details of location, plus an agent’s brief describing the proposed works.

8. How long will a decision take? In most cases a decision will be made within eight weeks. Large or more complex projects could take longer.

Facilities may be required to blend in more closely with the surrounding environment

9. What do you do if your application is refused? If you are refused permission or are unhappy with the conditions imposed on the permission, you can ask your planning authority if your proposal can be modified to help it gain acceptance.

Ceramic grandeur Over 3000m2 of Shackerley's Sureclad ceramic granite cladding was installed on behalf of Miller Construction by total building envelope contractor Norking Aluminium of Doncaster

The availability of highly polished Sureclad ceramic granite facade panels, in a wide range of colourways and formats, is providing architects across the UK with new ways to give buildings a luxurious standout appearance, says Shackerley, a leading supplier of ceramic granite ventilated cladding systems.

S

peaking of the material’s benefits, Shackerley CEO Brian Newell says: “Ceramic granite is an exceptionally versatile building material that can be produced in a vast array of styles and colourways to meet any aesthetic brief. Our mirror-finish Sureclad facade panels in traditional rectangular and contemporary square formats are increasingly popular because they deliver sustainable, external ventilated cladding with the visual appeal and natural appearance of highly polished stone such as marble or granite, but at a fraction of the cost, and with much lower loadings on the building.”

The luxurious aesthetics that can be achieved are exemplified by a recently completed project, where the reflectivity of this attractive versatile material has been used to great effect

by Ryder Architecture.

the-art facilities wrapped around a stunning central atrium. Externally, the University Centre makes a strong visual statement and is equally impressive thanks to Ryder’s specification of a white polished ceramic granite ventilated facade panel from Shackerley’s Sureclad Collection.

“We were asked to create a flagship building,” says Ryder Architect Mark Clasper. “Our client wanted us to create a very clear distinction between the new University Centre and the existing Further Education buildings – somewhere aspirational that students could progress towards.

“We chose Shackerley’s white polished ceramic granite cladding primarily for its aesthetics. We wanted a unique, premium material that would help to add a ‘sense of grandeur’ to the University Centre within its surroundings. The building is set amongst dense mature trees, so reflectivity was an important factor.

Streamline appearance Because of the project’s scale and tight deadlines, Norking and Shackerley’s technical experts worked very closely together to ensure the smooth running of the project at every stage. This was Norking’s second Sureclad installation, which they completed on schedule, successfully creating interfaces with the external glass balustrading and Schueco glazed windows, delivering sleek streamlined elevations interrupted only by the recessed window reveals.

Commenting on the project Mark Clasper says: “We had assistance from Shackerley’s sales and technical

teams right from the start when we began to develop the specification at tender stage and also through the design development phase. Shackerley then went on to assist with the construction detailing. The installation team from Norking completed the cladding to a very high standard indeed and we were particularly pleased with the way they achieved the required interfaces with the window cill, head and jamb flashings.”

Mark concludes: “The new University Centre at Grimsby is the third major

development Ryder has completed using the Sureclad system and once again we have achieved excellent results. We recently handed over a prestigious hospital building and a police headquarters clad with ceramic granite ventilated facades and currently have two additional major developments on site that also incorporate Shackerley’s system, where we look forward to having similar success for our clients.”

“Depending on the time of day the elevations appear to have a mirrored finish, allowing them to take on the colours of the surrounding trees, landscape and sky.”

Appearances, although critical, were not the only reason why Shackerley’s Sureclad ceramic granite ventilated facades were installed, as Mark Clasper explains: “As the primary envelope cladding for the University Centre, it was important that the material we selected was sustainable.

The ceramic granite scored an A rating in the BRE Green Guide to material specification, contributing to the credits we achieved under MAT1.”

The building subsequently attained a BREEAM rating of Very Good.

Over 3000m2 of Shackerley’s Sureclad ceramic granite cladding was installed on behalf of Miller Construction by total building envelope contractor Norking Aluminium of Doncaster. All panels were prefabricated at Shackerley’s ISO 9001 accredited production facilities in Lancashire and supplied to the Grimsby campus ‘installation ready’ – predrilled and bracketed using a patented undercut anchorage system to provide a secure mechanical fix to the Sureclad aluminium substructure (compliant with BS 5385 Part 2).

The panels had been specified in an optimal 1200 x 600mm format to minimise cutting and material waste and Shackerley also supplied Norking with ceramic granite pieces cut to bespoke sizes for corner detailing.

esigned by renowned architect Berthold Lubetkin, George Loveless House and the neighbouring James Hammett House were two of the first to feature high level blocks using reinforced concrete.

But over the years, the two blocks had fallen into disrepair and the external coatings, walkways, columns, decks, aggregate panels and mastic joints were in need of a serious refurbishment.

Following an assessment of the properties, consulting engineers, Engineering Design Associates, created a specification that was designed to repair and protect the building through the use of high performance mortars, corrosion management systems and sealants produced by Sika.

Sika’s Armocrete, a cementitous free flowing micro-concrete repair system, was used to repair large sections of the

Another vital requirement was the sealing of all joint repairs on the blocks to create a water and air tight building envelope.

With incorrect specification of sealants often resulting in failure in the form of water ingress, air leakage, staining of building materials plus the associated cost with putting this right, Sika was able to advise on the best solution. This saw the use of Sikaflex AT Connection, a onepart moisture curing elastic sealant based on Hybrid Polyurethane technology.

To complete the repairs, the balcony desks, which were badly cracked and letting water through, were attended to. To tackle the repair, the Sikafloor Pronto fully fleeced system was used. Comprised of a low viscosity primer, a self-smoothing screed and a flexible acrylic seal coat, the system offers excellent mechanical, chemical resistant and weathering properties.

Featuring PMMA (polymethyl methacrylic), the extremely fast curing non-slip resin flooring system is ready for foot traffic after one hour and fully cured after two, helping to minimise any disruption to the blocks residents.

With each of the Sika products offering a proven track record exceeding the requirements of BS EN1504, the regulations for concrete repair and protection, and an easy installation process once on site, the concrete repair system specified offered Tower Hamlets Homes a cost effective and reliable way to repair the damaged areas and extend the life of its properties. The families that live in the two blocks now benefit from its attractive new appearance and additional peace of mind that the structure is protected from the onset of any further degradation for years to come.

Steni cladding helps colour landmark BSF project Three shades of rainscreen cladding panels from Steni UK were specified for the redevelopment of one of Cambridgeshire's two first _ and last _ BSF projects for their aesthetics and robustness.

More than 1000m² of Steni’s Colour panels, in blue, grey and white, feature horizontally on the second floor facades of the new-build main hall, dining hall, kitchen and classrooms at the NealeWade Community College in March.

They were specified in a pattern of alternate inverted triangles by main contractor Galliford Try’s design team RH Partnership Architects and installed by specialist sub-contractor Task Contract Services. Manufactured from a fibreglass reinforced polymer composite, they feature a surface of electron beam cured acrylic that is applied without the use of solvents.

RH Partnership advised: “We specified the Steni panels because of the good selection of colour which gave us the aesthetic appearance we desired as well as the robust performance, specifically excellent scratch resistance, which is required for the severe education environment.”

The £26m project caters for 1500 11 to 16-year-olds and 280 sixth-formers as well as the local community who have access to the refurbished sports centre. The 30-month build is being completed in three major and almost 20 minor phases as the school had to remain operational throughout.

The new buildings were constructed lightweight of steel frame and crosslaminated timber panels with curtain walling, feature window panels and dark engineering facing brick with the Steni rainscreen system fitted above.

With financial close on the Cambridgeshire BSF programme being reached in May 2010, a month before work started on site with the demolition of some existing buildings, the scheme avoided the cull from the Government’s review of the school building programme.

Award-winning insulation Norfolk-based practice Parsons + Whittley Architects has won the residential category of the first ever UK Passivhaus Awards for a scheme which was insulated with Styrofoam insulation. Parsons + Whittley won the much sought after award for the Wimbish Passivhaus project, a scheme of 14 dwellings designed for Hastoe Housing Association which delivers extremely low fuel bills and has minimal carbon emissions. The buildings were insulated below the concrete floor slabs with Floormate 300-A Styrofoam insulation from Dow Building Solutions. Manufactured in nearby King’s Lynn, the material is highly durable with excellent moisture-resistance and compressive strength, enabling it to perform outside the waterproofing envelope. dbsuk@dow.com enq 025

Kemper system has refurb in the bag Ball Packaging has carried out a successful roof refurbishment project thanks to Kemperol V210 from Kemper System. When the existing 16,000m2 aluminium standing seam roof at the Wrexham production plant started to show signs of wear, the company needed to find a solution that would enable a roof refurbishment programme with as little disruption as possible.

Kemperol V210 from Kemper System was the only solution that met all of Ball Packaging’s exacting requirements. A cold liquid-applied system installed in a single process, the Kemperol V210 liquid resin saturates a non-woven reinforcement fleece and cures to form a tough, seamless membrane that bonds permanently to the enquiries@kempersystem.co.uk enq 026 substrate and cannot delaminate.

VMZINC provides Royal roof

A standing seam, natural VMZINC roof has been used in Scott Brownrigg’s design of the new £16m home of the King’s Troop Royal Horse Artillery. Europe’s biggest zinc project in the past year achieved a BREEAM ‘Excellent’ rating with zinc chosen for its overall sustainability.

The metal complements timber cladding on buildings which provide stabling for 170 horses, a museum, veterinary clinic, saddlers’ and tailors’ workshops and the largest, most modern blacksmith’s forge in the British Army. The site is ‘carbon minus’ with surplus energy generated using bio-fuel derived from horse manure and bedding.

Prevention cheaper than cure

Sarah Barsby, Marketing Director for Intastop explains why door and wall protection is a key item to add to your maintenance itinerary.

A

s austerity takes grip of the country resulting in the inevitable tightening of purse strings, building owners, operators and estate managers are finding balancing funds against maintenance costs extremely challenging. Understanding the duty of care to ensure their building is fit for purpose and its occupants are comfortable in their environment, more managers are now looking at cost effective products that can help prevent damage, provide durability and offer longevity.

From large scale re-fits through to decorative maintenance, the ongoing upkeep programme of many buildings poses differing challenges for estate managers. The diverse nature of public buildings together with their intended use can mean a multitude of considerations for the maintenance itinerary. For example clinical buildings such as hospitals, health centres and medical facilities place huge emphasis on cleanliness and the importance of an

infection-free atmosphere.

In addition, these buildings experience high traffic areas and have a need for protective products, in particular for doors and walls. In general a product that can offer protection whilst at the same time provide aesthetic qualities for the built environment has to be an essential element to any maintenance programme.

Cost-effective protection Doors and their surrounding surfaces in busy access zones and high traffic areas are subject to extremely high levels of wear and tear, which can rapidly lead to expensive repairs and frequent repetitive maintenance. By preventing the damage from occurring in the first place the cost of door replacement is greatly reduced plus there is no compromise on safety and security.

Products on the market include post formed fully clad door sets or frame guards. Both provide an aesthetically pleasing and versatile long-term solution to ugly, hazardous and

damaged door surrounds.

Intastop is a leading UK manufacturer of door and wall protection products, with 20 years of experience in meeting the demanding needs of hospitals, airports, supermarkets and similar locations. Intastop offers a range of innovative and cost-effective protection solutions that increase building life and reduce maintenance bills.

Intastop’s range of frame guards are designed to protect the pull and push side of door frames as well as the vulnerable rear edge of the door. Key to reducing on-going maintenance costs is the quality of the product that bears all the UK fire safety and EN standards.

Intastop Rigid Frame Guard in a high quality aluminium that incorporates a PVC-u insert secured into the guard. The standard finish of the guard is in satin anodised aluminium (SAA), however aware of the different commercial finishes required to ensure facilities are refurbished to a high standard, Intastop provides other anodised finishes or colour coating, including wood effect.

Aesthetics aside, choosing the right product for the job is important. Looking at the door itself and its operational requirements there are different options available. Slimline guards can be used on frames with no door opening restrictions and for architraves up to 50mm. Alternatively, standard guards are ideally suited for the push side of the door and protects both the frame and the rear edge of the door when it is in the open position and are primarily suited for architraves up to 100mm.

Doors & Windows

Dempsey Dyer's high rise achievement Goodman Fields is a high profile development ideally located for Canary Wharf, Docklands and South Bank. Designed by Lifschutz Davidson Sandilands, together with Townshend Landscape Architects for Berkeley First, the development will comprise a selection of high quality studios and apartments as well as retail and commercial space, student accommodation and a hotel.

Trade and commercial manufacturer Dempsey Dyer has been awarded the contract to supply the windows for the £80m high rise student accommodation block.

Great emphasis has been placed on the sustainability of the building, so the energy efficiency of the windows was of key importance. Coloured profiles were also specified, but the contractors were looking for added reassurances knowing how quickly a sub standard product can start to fade and look shabby. Finally, the contractor needed to have experience of working

on high profile developments.

Martyn Wright of Dempsey Dyer and John Duckworth of Deceuninck worked together to put together a tender that amply demonstrated Dempsey Dyer’s credentials and the quality of the Deceuninck product. The tender specified tilt-only windows in Anthracite Grey using the Deceuninck 2500 chamfered system. The energy efficiency and superb performance of these windows gave valuable reassurances on the sustainability front.

The profiles are coated using the unique patented Decoroc process

which gives a matt satin finish that’s guaranteed colour fast for 10 years – a guarantee that the specifiers found very attractive. And while Dempsey Dyer was able to provide an impressive portfolio of references, having previously won the contract to install 1500 windows in an 18-storey tower as part of phase two of the £215m project to regenerate Aston University’s student accommodation, the specifiers had firsthand evidence of the quality and experience of Dempsey Dyer.

Available in eight strong and contemporary shades, each incorporating a black base yarn, Coral

Welcome responds to the continued demand for linearity in design and can deliver an unequivocal design statement in the all-important entrance area of a building.

A highly efficient ‘wipe-off’ system, Coral Welcome can stop up to 90% of footborne dirt and moisture entering a building, which can ultimately can save up to 65% of the life-time costs of keeping interior flooring surfaces clean.

Committed to reducing its environmental impact by 25% by 2015, as measured by Life Cycle Analysis (LCA) Forbo has used 100% recycled Econyl yarn to produce Coral Welcome, whilst the primary backing is made from recycled PET bottles and recycled yarn.

Furthermore, all of Forbo’s own yarn waste is also sent back to the main supplier to be regenerated into new yarn. As Coral Welcome is produced in a manufacturing plant that has achieved virtually zero landfill, this innovative entrance flooring system can be classed as a ‘closed loop’ product.

Dulux trade paint helps new sporting village shine A range of coatings from leading paint manufacturer, Dulux Trade, has been used to give an impressive finish to a new state-of-the-art sporting village in Basildon. Products, including coatings from the Dulux Trade Metalshield and Diamond range, have been applied at the facility, which is part of a multi-million pound regeneration programme in the town.

The project is a joint public and private partnership scheme between Basildon Borough Council and Community Solutions for Leisure (Basildon) Ltd, which is a subsidiary of Morgan Sindall Investments Limited. Construction work was carried out by Morgan Sindall plc and the facility is operated by SLM Ltd under its banner, ‘Everyone Active’.

Paul Clayton, from S&P Architects, was in charge of specifying the products used in the project. He explains his choices: “Given the brief that I was presented with, and the differing surface types that needed coatings in the project, I selected a variety of products to meet a multitude of requirements.”

Paul specified Diamond Matt for the internal wall areas and Diamond Eggshell for the interior wet wall and ceiling areas. The Diamond Technology incorporated in the range of coatings makes it 10 times more stain resistant than standard water-based eggshell finishes and 10 times tougher than vinyl silks, therefore reducing the long-term environmental impact.

Phil Morris, contracts manager for Coldec Ltd, states: “This was a large project with strict timeframes, so was quite challenging from the off.

Fortunately, we enjoyed working with the Diamond range products and the coatings definitely helped to make the

job easier for us. They have a great spread rate and sleek finish, but are also tough and durable coatings.

“A further challenge of the project was the grandstand, the top of which could only be reached by a mechanical lift. Luckily, we used the Dulux Trade Metalshield system on the steelwork, which gave great coverage and could be recoated quickly. It’s also designed to last for eight years, so it will be a while before we have to get back on the lift. Overall, we worked with high quality products to deliver a fantastic end result. We walked away with a real sense of pride.”

A haven for heat pumps Orkney Housing Association has installed NIBE Exhaust Air Heat Pumps across 264 of its affordable homes, designed to provide its residents with comfortable, energy-efficient living environments matched with significantly reduced energy bills.

The Exhaust Air Heat Pump system from NIBE recovers warm stale air from inside the property and feeds this back to the heat pump through a ducting system. The energy from this air is then reused to heat the property and hot water. Once the heat pump has extracted the energy it needs from the recovered warm stale air, the used cold air is released outside and fresh air is drawn back into the building.

Green university opts for Escot energy sub-metering system Escot, a clip-on sub-metering system by Marshall-Tufflex Energy Management, is making easy work of monitoring the energy consumption of Manchester Metropolitan University's (MMU) environmentally-friendly Crewe campus in a drive to better inform the facility and its students about energy usage and enable it to further reduce its carbon footprint.

As part of this initiative, the university has installed 40 hi-tech Escot clip-on sub-metering units within three halls of residence at its Crewe campus. Escot provides an in-depth view of overall consumption as well as localised usage and provides an alternative to installing many meters with different circuits

for heating, lighting and power. The university hopes to make the energy usage information available to students to engage them in saving energy.

Compared to traditional sub-metering systems, Escot not only reduces installation work but also provides more information. The automatic

energy data capture units utilise clip-on transducers that transmit a low voltage signal of equal proportion to energy consumption and eliminate the need for a three phase voltage connection.

The signal is recorded by an integral data logger, allowing users to produce graphical analysis and CSV files using Deltrax software, which enables captured data to be quickly and easily downloaded.

MMU Estates Manager Mike Neary says: “Ease of installation was one of the main reasons for trying Escot and it has proved itself by going in very smoothly, connecting straight to the distribution board.”

The Escot sub-metering system can be also be fitted to a sub-station to determine spare capacity on its mains feed to avoid overloading an electrical distribution system or individual circuit.

It is one of a range of non-invasive systems by Marshall-Tufflex Energy Management that are easy to install and can be fixed or portable, depending upon the individual application.
