TNG’s expertise fits the bill for new police HQ

A new police building in Jersey has been delivered on budget and ahead of time thanks to the technical expertise of the team at TNG Consulting Engineers.

Acting as M&E Co-ordinator, the Southampton-based engineering specialists provided both advisory and supervisory services for the purpose-built police station in La Route du Fort in St Helier.

Directors Russ Pitman (MD) and Ralph Boden worked on behalf of the main contractor, ROK Regal Construction Ltd. TNG’s services included the assessment of the tendered design and the proposals for the mechanical and electrical systems, advice on the M&E programme of works and the management of the Ministry of Justice commissioning procedure.

Russ Pitman also chaired the M&E co-ordination meetings, carried out site inspections and was responsible for the commissioning programming for the £24M project.

The new building is unique as it combines police headquarters with an operational police station, custody suite and emergency command centre. This means that for the first time ever, all of the States of Jersey Police functions are located together.

Russ Pitman, TNG’s Managing Director said, “We were honoured to play a part in constructing this impressive building, which will play a critical role in serving the local community for many years to come.

“The TNG team pulled out all the stops to ensure this high profile project exceeded expectations, and we were delighted to complete the work ahead of schedule and within budget,” added Russ.

The States of Jersey Police’s Chief Officer was so impressed by the Team’s work, that he wrote a personal letter of thanks.

Mike Bowron, QPM (Queens Police Medal), said, “I have been particularly impressed by the team ethos, joint approach and shared effort that has been undertaken by the design team and specialists to deliver this fantastic facility.

“Every team member has played a critical role in bringing this project to fruition and I’d like to thank TNG for its dedication and professionalism. You have produced an excellent building of which you can be truly proud,” added Mike.





How affordable desktop solutions can boost workplace wellbeing and drive productivity

The health and wellbeing of employees in the workplace has never been more topical. In an age where recruiting skilled workers is becoming more difficult and industry wide technological disruption is evolving at such a rapid pace, retaining talent is critical for any organisation looking to thrive and succeed. Vital to that success is the employee experience, which incorporates wellbeing.

Happy and healthy employees will stay longer, however the benefits of addressing workplace wellbeing extend far beyond possible hiring and training cost savings. Instances of absence and illness can be improved through implementing a comprehensive workplace wellbeing policy whilst engagement and productivity can be drastically impacted across the entire workforce. Perceived physical and psychological health contributes significantly to a building occupant’s sense of wellbeing and can be influenced by a number of environmental factors.

Daylight & lighting

Overhead office lighting typically outputs light in the 300 lux range. It is well understood that poor quality light produced by fluorescent tubes can lead to eye strain and headaches and it can be difficult to provide enough good quality lighting that benefits everyone.

Focusing on desktop and individual workspace solutions should feature as part of any company’s overall approach to health and wellbeing. Issues such as the impact of good quality desk lighting can be significant in improving a person’s ability to concentrate, energy and alertness. The advancement in LED technology offers a modern alternative to conventional lighting, delivering improved light quality. Providing affordable desk lamps is easy to implement across an entire office and provides a customisable solution to individual employees.

Indoor air quality

The quality of air has been heavily researched in the workplace. Employees showing symptoms of ill health in the office, such as fatigue and eye irritation, often attribute these symptoms directly to their work environment. Anyone can be affected but workers in open plan offices have been shown to be particularly vulnerable.

People spend approximately 90% of their time indoors where the air can typically be 2-5 times more polluted than outside. It is important to ventilate the air and provide solutions to alleviate any signs of poor air quality before symptoms arise. Pollen is particularly troublesome at this time of year, with around one in five people in the UK suffering from hay fever. Pollen allergies are linked to a decrease in efficiency at work. A study by the National Pollen and Aerobiology Research Unit found that sufferers of hay fever were working at only 63 per cent of their normal productivity1. The development in personal air cleaning technology offers an affordable solution, as these devices can help to effectively remove dust, germs and allergens and help workers feel more alert.


Distraction from noise can considerably impact productivity and is often quoted as one of the leading causes of distraction in the office environment by personnel. As we seek fresh air and daylight, opening windows only exacerbates this problem as ambient noise from outdoors floods in.

Reverberation time in a typical office is about two seconds (the time it takes for a noise to dissipate). In open plan offices, increased levels of reverberation often results in the need to speak louder as it becomes increasingly harder to hear clearly and concentrate on the task at hand. There is a careful balance to be struck between providing an environment which encourages collaboration and one that condones noise distractions.

Dividing up workspaces and deploying noise reducing technologies is an effective way to drastically reduce the negative impact of background noise. Utilising existing wall space to install noise absorbing panelling can effectively reduce reverberation times. Aim for a comfortable reverberation time of one second as this is the recommended level for an office environment.


Retrofit health and wellbeing products empower employees to take charge of their own wellbeing and proactively search for products that suit their individual needs. Ergonomics of the workspace cover support for the back, neck, eyes, wrists and legs and are a key factor in the overall wellbeing of the workforce. However the UK lags behind its European counterparts in this area.

Sit-stand desks have been hailed as a breakthrough for cutting the prolonged periods of sedentary work in the office. Giving employees the option to stand for a few hours during their day can significantly contribute to a more energetic workforce and is a simple initiative employers and those responsible for the work environment can implement company-wide.

Impactful solutions

According to research carried out by ACCO Brands last year, nearly half of office workers expressed an interest in products specifically aimed at improving the overall environment of their workplace. If each employee is given the opportunity to enhance their own wellbeing and personalise their workspace, businesses can expect significant returns. Current estimates suggest that every £1 spent on improving workplace wellbeing represents between £3 and £6 in productivity and efficiency gains2.

Are your fire doors safe and legal?

Nick Goddard, Research and Development Manager at Geofire has been in the fire safety industry for over 20 years. Here he talks about the importance of fire doors and the technology available to hold open fire doors safely and legally.

Fire doors are designed to prevent the spread of smoke, flames and toxic gases throughout a building in the event of a fire. However, when a fire door is held open, fire can quickly pass through the building, blocking escape routes and endangering lives.

Legally, a building’s fire doors must therefore be self-closing to ensure the door closes to act as a barrier that stops the fire from spreading.

Due to the level of protection a fire door provides, the placement and weight of the doors is often restrictive for example in a care home setting for residents, or for pupils in a school.

It is recognised that in these cases it is necessary to hold fire doors open for practical reasons. In this instance the fire door must have a device installed to release the door, so that is will close upon activation of the fire alarm system.

Holding open fire doors legally

Making sure fire doors are closed when the fire alarm sounds is extremely important. The British Standard 7273-4:2015 Code of Practice for the operation of fire protection measures – Part 4: actuation of release mechanisms for doors gives guidance on the installation, commissioning and maintenance of fire door holding systems. The system/hardware used to hold the doors open must also be approved to EN1155 standard.

Fire door retainers, also known as fire door holders, use a magnet to hold open heavy fire doors that will release in the event of a fire. Stand-alone door retainers are suitable for doors that already have a closing device fitted, however fire door closers with a built in hold open function are also available.

Depending on the installation and level of protection required, there are a variety of fire door retainers readily available which react to different triggers, in the event of a fire.

Hard wired fire door retainers

Hard wired fire door retainers are used all over the world and are ideal for new buildings as they have a direct wire connection to the building’s fire detection system. In a normal condition, power (usually 24 V dc) is supplied to the door retainers so that they can hold the doors in an open position. When a fire is detected by the fire panel, power is cut releasing the doors so that they can close. A fault in the wiring or power supply to the door retainers will cause them to fail safe and release the doors. Hard-wired fire door retainers are available in many shapes, sizes and finishes to suit all applications.

Radio controlled fire door retainers

Radio controlled fire door retainers are triggered wirelessly by radio waves from a controller connected to the existing fire panel or interface unit. As minimal wiring is needed, these are often used for fitting into large, existing buildings but still offer high levels of protection. These systems are installed by an approved, trained professional as a site survey has to be carried out prior to installation.

Sound activated fire door retainers

Sound activated fire door retainers react to the noise of the fire alarm and some devices can learn the sound of the building’s specific fire alarm, so they will only release when the alarm sounds. This is a cost effective solution as there is no need for wiring to a fire panel.

Sound activated fire door retainers are battery powered and can be installed quickly and easily. They are wire-free, so installing them won’t affect a building’s infrastructure.

Innovators of fire technology

Geofire has been designing and manufacturing electromagnet fire door holders and closers for 45 years from its factory in County Durham. Established in 1972, the company is still continuing to invest in research and development to be able to offer cost effective and innovative fire technology.

Andy Collinson, CEO at Geofire, said: “What makes Geofire stand out from the rest is that we design and manufacture all of our products in the UK, and we are very proud to be able to say that.

“We have a solution available for all installations, whether it is a new build using our hard-wired products, a noisy environment where radio would be more suitable (Salamander) or, where an acoustic solution is required to close the fire doors upon hearing the sound of the fire alarm (Agrippa).” Email: Tel: 01388 770 360


Hot desks, cool design

Workplace design is not just about configuring the layout of desks, chairs and meeting rooms – it’s about strategic assets that need to be managed effectively, according to the CEO of one of the UK’s leading FF&E specialists.

And Andy Kendall-Jones, who heads the Southerns Group, an organisation made up of six businesses, knows all about the effective management of assets and the importance of workplace design.

“The tight correlations between personal interactions, performance, productivity and innovation are of primary interest to any business leader – or they should be,” he said. “It is difficult to overstate the importance of workplace design. It is a key part of facilities management (FM), on the basis of FM being responsible for coordinating all efforts related to planning, designing and managing buildings and their systems, furniture, fixtures and equipment, so as to enhance the organization’s ability to compete effectively. Employers are switching on to the benefits of enhanced office space. Whether it is ergonomic furniture, flexible working areas or even unique communal spaces, the boost to both employee wellbeing and productivity can be substantial”

Southerns itself is a fixtures, fittings and equipment specialist working across the health, education, corporate and retail sectors; within the Group is the renowned workplace design consultancy, SpaceInvader, the highly respected interiors consultants Ralph Capper and Broadstock, leaders in the field of learning environments and associated workspaces.

“Research and development drives the strategy of the Group,” Andy explained.  “We are always looking at new ways of working, collaboratively engaging with end users and their employees, consulting with internal and external focus groups – pre and post-delivery – and discussing the best way to enhance our clients’ key working relationships.”

It’s through this genuine collaboration with clients, and the development of long term relationships that benefit both parties, that the firm has grown to one with projected revenues in 2016-17 of £45m, employing more than 200 employees across locations in Leeds, Manchester, Macclesfield, Bolton and London. The Group provides commercial workspace solutions, offering consultancy, design, project management, manufacture, supply and installation, together with ongoing lifecycle management of clients’ FF&E assets.  Each company within the Group brings a very particular component to the table, working entirely independently but at the same time, offering services that complement one another.  Ralph Capper, for example, will often be called upon to consult with a client in order to advise on and select key signature pieces for a workplace design scheme.  Andy Kendall-Jones has created a unique think tank, combining general with specific expertise across multiple sectors.  It’s a winning formula, with some of the world’s biggest blue chip companies coming to the Group for its unique proposition.  Headline projects include Ralph Capper providing workspace design for the ground-breaking Central Square mixed use development in the heart of Leeds’ business district, and Broadstock working with Tata Technologies to design and supply furniture for all of the internal space at the conglomerate’s state-of-the-art, new European Headquarters in Leamington Spa, Warwickshire, the first new contract achieved since the establishment of the firm’s Commercial Interiors Division.

“Workspace design can be tailored specifically to a client’s needs so that the design solution matches its business agenda,” said Gavin King, director of SpaceInvader, part of the Southerns Group, and an expert in strategic workplace consultancy.  Gavin, who leads project teams on long-term briefs including AstraZeneca’s global property portfolio, said: “The key to successful workplace design is the linking of human behaviour to the organization’s overall vision.  Your people are your greatest asset and you can draw a direct line from their success to that of the business.”


AstraZeneca, Middlewood Court, Macclesfield

SpaceInvader was appointed to create a world class workplace for up to 1000 AZ employees within Middlewood Court, on its Macclesfield campus. The project provided an exciting opportunity to re-purpose a fading building, originally built as a manufacturing and packing facility in the 1960s, and re-define the future of AstraZeneca’s workplace portfolio. It was clear that this would not be an isolated project, and additional consideration was required to fully understand the significance of the commission within the wider context of the campus.

The key priorities set out by the client were to instil a sense of pride back into the Macclesfield campus, to retain and enhance the company’s presence within the North West and relocate some of the core corporate departments alongside the manufacturing heart of the firm.

Championed by such a forward-thinking client, this project has delivered a workplace transformation and complete overhaul of a once conservative, insular internal culture and way of working. The design process and finished product has been so successful that it will now go on to inform a more progressive approach to workplace design across all AstraZeneca sites.



Boon Edam provides secure and stylish entry solution for The Francis Crick Institute

Boon Edam, a global market leader in entry solutions has unveiled a quality, engineered solution for a brand new, state of the art building in St Pancras; now home to The Francis Crick Institute.

The biomedical discovery organisation, required an entry solution to seamlessly integrate with its new building’s modern design.

The research centre, a flagship for UK biomedical science and one of Europe’s largest biomedical research facilities, is a base for 1500 scientists and staff, whilst housing technology to help create discoveries for illnesses such as cancer and heart disease. Therefore, the entry solution required advanced security to ensure staff, visitors and equipment could be kept safe and protected, whilst complimenting the design.

With 140 years’ experience with manufacturing entry solutions, Boon Edam ensures its products meet the strictest quality standards. The building is serviced by five Automatic Crystal Tourniket’s. This product was selected following an assessment of everyday use including analysing the number of visitors and size of luggage expected to be carried into the building whilst creating a user friendly and attractive gateway into the building supporting the green principles that were embedded into its design and carried through to its operation.

The revolving doors use a combination of laminated and toughened glass, which results in a reduction in the traditionally framed elements of the door. The minimalistic, all glass revolving doors provided a stylish solution which complimented the new building’s façade. They also met the security requirements; with each Crystal Tourniket supplied with an external night locking door. Finished in stainless steel, the additional feature provided a further layer of security for the building. The night locking door was mounted onto a stainless-steel track fixed to the glass soffit and provided with fully integrated locks.

Ian Goldsmith, Head of Sales at Boon Edam Ltd commented, “We are thrilled to have provided the entry solutions for this building. The cross-border project between Boon Edam BV (Netherlands) and Boon Edam UK was successful in meeting the precise requirements of The Francis Crick Institute. The Crystal Tourniket’s have provided the new building with the secure, eye catching solution desired whilst utilising the environmental benefits of installing a revolving door.”


Hackney Community College saves £25K a year with second major Salix-funded LED lighting upgrade

Following a successful LED conversion project by Energys Group in 2015, 2016 has seen the East London college make a further investment in the latest Energys lighting technology.

 Energys estimates that combined savings of the two projects will be £95K per year.

During the second half of 2015, Hackney Community College (HCC) in Shoreditch, East London, implemented a substantial lighting upgrade that resulted in more than 4,900 lamps being converted to LED. The new systems were supplied and installed by Energys Group, which also provided boiler optimisation controls and specialist insulation as part of a far-reaching energy efficiency initiative.

With expected annual savings of £70,000 and a return on investment (RoI) of only 2.8 years on the lighting side of the project alone, its impact has been significant. It is perhaps unsurprising, then, that HCC recently decided to move ahead with a second lighting upgrade – this time focusing on internal spaces not covered by the earlier project, as well as external areas of the campus.

“The Energys LED lighting has brought a definite, cost-efficient improvement to the quality and comfort factor of lighting inside the college, and it made sense to optimise the remaining areas in a similar fashion,” says HCC Communications Director Ruth Lomax. “This time work focused on the dance and performing arts studios, a number of classrooms and offices, corridors, and outdoor areas of the campus.”

Energys’ Business Development Manager, Raj Gunasekaran, adds: “As with the previous project, it was evident that the latest generation LED lighting could deliver significant cost reductions for the college. We specified a number of our most popular current products during the Phase Two upgrade, which took place over the course of four weeks in autumn 2016.”

Salix success again

As in Phase One, Energys was able to bring its comprehensive knowledge of the Salix funding scheme to the table. Once again, the college secured financial assistance under the Salix College Energy Fund with the assistance of the Energys team.

The project called on a variety of products from Energys Group’s industry-leading New Vision range. In the internal areas, specified items included LED tubes, panels, downlighters, wall lights, dimmable solutions and spot lights. Outside, the new installation comprises a blend of LED uplighters, bollard lights, eyelid wall lights, photocell units, floodlights and path lights.

The project was completed to a stringent and quick-turnaround timetable, but its benefits are likely to be long-lived indeed. Energys estimates that the new internal lighting will save the college £16K a year, with a return on investment (RoI) of 2.6 years. Meanwhile, forecasts indicate that the new external lighting will save £9K a year, giving the college an RoI of 4.5 years.

“These are compelling figures,” says Gunasekaran, “and underline the benefits that LED lighting has both in terms of immediate and longer-term energy savings. With increasingly stringent carbon targets in mind, more and more schools and colleges are now converting to all-LED infrastructures, and we expect that trend to intensify in 2017 as awareness continues to grow.”

The college is full of praise for the Energys team’s ability to supply and install such a substantial amount of new lighting technology in what was a very limited timeframe. “The project went smoothly and there was no impact on college activities,” said Ruth. “But above all we would highlight the quality of the new lighting – it is much more consistent and comfortable for staff and students.

“We had high expectations of Energys and its LED lighting systems after Phase One, and we are delighted to confirm that they have been fully satisfied.”


A fresh approach to ventilation

“A healthy indoor climate is recognized as a basic right. People spend a large part of their time each day indoors: in homes, offices, schools, health care facilities, or other private and public buildings. The quality of the air you breathe in those buildings is an important determinant of your health and well-being. The inadequate control of indoor air quality therefore creates a considerable health burden” (The World Health Organization 2009)

Ensuring good ventilation within buildings has always been a challenge, and there are many buildings built even today that still suffer from poor ventilation. While the goal of saving energy is commendable, at times this is the overriding factor and can have a dramatic negative effect on the internal air quality.

Airtight buildings are designed to retain heat. This means the air in the building can be recycled many times which leads to a build-up of pollutants, toxins and bacteria which are then continuously breathed in and out by the occupants. Indoor air quality has a major influence on health as stated by WHO, but still the comfort and well-being of the persons inside is often overlooked. Poor air quality has been linked to a problem known as the Sick Building Syndrome which can reduce productivity in offices and impair learning in schools, and lead to the spread of viruses and airborne illnesses.

We spend an average of 90% of our time indoors and so expose ourselves to these many airborne pollutants which can cause respiratory problems and other symptoms such as headaches, itchy eyes, sneezing etc. It is recognised that theseis are synonymous with high humidity levels.

By installing good ventilation, you can create an environment that is healthier and cleaner to work and live in whilst contributing to easing the building long term maintenance. But the question is what solutions are available?

Traditionally there have been powered ventilation systems (MV and MVHR) available for many years which whilst acknowledged as improving ventilation have two drawbacks: first, you obviously need power! which costs money, and secondly to be truly effective you need warm air (warm air collects more water vapour than cool air) and this is even more expensive.

An alternative product that has recently entered the UK market is the SolarVenti Ventilation panel. Designed manufactured and launched in Denmark in 2001, and already with 80,000 installations in 25 countries, the SolarVenti product offering is unique as it uses solar power to warm the air and power the fan, and so creating a zero-running cost system.

The SolarVenti fan produces a positive pressure within the property so allowing the moisture to be pushed out through vents or by natural air leakage.

The Science behind SolarVenti

Air that is warmed after passing through the SolarVenti panel has the same amount of moisture as when it entered the panel at ambient, but once the temperature of air rises above the ambient then its ability to absorb moisture rises and at higher temperatures then this ability to remove moisture rises dramatically (this can be as much as 60% higher than the ambient air). This is because warmer air has a greater space between its molecules and therefore is able to absorb water molecules. The warmed air acts like a sponge when inside the house absorbing the moisture in the air.

How SolarVenti Works

  1. Solar radiation starts the collector operation by initiating the patented internal solar PV panel which starts the fan
  2. Fresh dry air is drawn in through the small holes in the perforated back plate which are designed to prevent insect ingression.
  3. Solar radiation warms the patented material in the SolarVenti panel which not only exchanges heat and warms the air as it passes through the material but it also acts as a secondary filter removing particles and pollen.
  4. Depending on the model approximately 35 to 200 m3 of warm air is drawn through the patented material in the SolarVenti panel and blown into the building. The temperature in the injected air is approximately 15°C-40°C above the outside temperature dependent on the solar radiation – this can be adjusted through the SolarVenti regulator control
  5. Humid air is driven out of the building through an a vent valve or natural losses through the cracks and crevices of the building.
  6. Cleaning the panel of any debris is a simple process of switching the panel off for a couple of hours periodically on fine days and this raises temperatures sufficiently to eradicate the debris.

SolarVenti panels have been tested by has been tested by Fraunhofer Institute and the Danish Technical Institute, for both performance and durability. It has also received the Solar Keymark and energy saving awards.

In addition, the units have already won the 2016 New Zealand Building Industry highly commended award in the category Innovation for the Healthy School Project This award came after a year-long study of the positive effect of installing SolarVenti on classrooms by the Massey University of New Zealand which concluded:

“Our programme is investigating the benefits of improved ventilation on school classrooms in New Zealand. We have completed a successful pilot study using SolarVenti in 12 matched classroom (six schools) which has shown significant improvements in classroom climate and energy use. In 2017 we will begin a larger study where we will monitor the indoor environment in 50 classrooms which will provide us with nationwide baseline of the conditions in NZ schools.”

Professor Phipps who has been leading the research says: Analysis of the data is on going, but it could be an effective tool in reducing incidents of Streptococcus within New Zealand schools,”


SolarVenti offer a complete range of solutions from ventilating small properties all the way up to large commercial buildings.

Some of the reason people may want SolarVenti

  • Landlords –  There are stories of tenants switching off powered ventilation systems in an effort to save money. A real consequence of this is that condensation then builds up and so increases the demand for maintenance, which in a catch 22 trade-off is almost invariably more expensive, but potentially with someone else(the landlord rather than the tenant) footing the bill!
  • Offices – Creating an environment that is comfortable to work in with fresh air ensuring less sick days and more productivity through greater concentration
  • Education – The Massey University study has shown that children benefit from the better environment in the classroom, and this will be studied in great depth in the next year.
  • Portable buildings and holiday lets – Offering free ventilation even when the property is unoccupied and so eliminating damp, mustiness etc.
  • Indoor Swimming Pools – A great way to reduce the costs of running expensive ventilation equipment to achieve the correct atmosphere

New research reveals outsourcing of security high but professionalism is paramount

Grosvenor Services study reveals requirements when procuring security

 Competence of staff and getting the supplier to deliver on the terms of the contract are the two main challenges businesses face when outsourcing their security, new research shows. At a time when businesses are increasingly alert to security threats, outsourcing is the most popular option according to independent research conducted on behalf of facility services specialists, Grosvenor Services.

Key findings:

80 per cent of those surveyed prefer to outsource security requirements rather than use an in-house team, with half preferring to use a provider specialising solely in security.

Those who were in favour of using a stand-alone security specialist were concerned that diversification would lead to a less than satisfactory service.

An alternative is a bundled FM contract, whereby a facilities management company manages several elements of service provision such as security, cleaning and grounds maintenance. 30 per cent of those surveyed said they would prefer to opt for a facilities management provider with security expertise.

A prime reason cited for this was ease of communication by having one point of contact for multiple services.

Professionalism of onsite staff was paramount for all those surveyed, whichever way security is managed. Compared to similar research conducted on the broader facilities management market, while both expect professionalism it ranks as the most important factor in the security sector, outstripping everything else. Investment in security could be undermined by less than competent staff which could have serious consequences for the security of a company.

Meeting changing needs

Bernard McCauley, Group Managing Director from Grosvenor Services, which also owns Charter Security, said: “Organisations looking to outsource need to be confident that the supplier they’ve selected has the expertise and innovation to meet ever changing security needs in a professional manner.

“Developments, including the application of new technology and the need for increased levels of security, have raised the bar in terms of service delivery requirements. It is now time to re-educate the marketplace about how much more a modern, professional security services provider can deliver, whether a stand-alone specialist or a full facilities services company.”

The survey was conducted amongst those with responsibility for purchasing security services and included security and FM managers, primarily in commercial offices and construction companies with over 100 employees based in London.

Wilson Access Machines Tackle Theme Park Ride

Wilson Access tracked mounted access platforms were hired by contractors working on one of the most thrill-seeking theme park rides at Flamingo Land in North Yorkshire.

Whittle Programmed Maintenance hired two Teupen Leo 21 machines for cleaning and painting work on the theme park’s extreme ride, the Flip Flop.

Andrew Simpson, Whittle Programmed Maintenance Operations Manager, said: “We told Wilson Access the type of work we needed to carry out on the Flip Flop and they conducted a site survey before recommending the Leo 21 machines.

“The Flip Flop ride is situated over a vast water filled basin and, once the water was drained away, we needed to get powered access equipment into the basin to begin our work. The Wilson Access machines were an excellent choice. Because they are track mounted they didn’t cause damage to the grassed area around the ride and easily negotiated the raised kerb surrounding the basin. They also offered our two-man crew easy access to the complex structure of the ride.”

The Wilson Access Leo 21 has a working height of 21m and an outreach of 12m. It is one of the few tracked mounted units to offer a full 250kg lifting capacity, even at full outreach. Its non-marking tracks means that it is ideal for internal applications and built in outrigger pads provide low point loadings for sensitive surfaces.



Kemperol protects Liverpool’s Royal Liver Building

Part of Liverpool’s UNESCO designated World Heritage Maritime Mercantile City, the Grade I listed Royal Liver Building is one of the city’s ‘Three Graces’ and an iconic waterfront landmark.

The building’s imposing façades are crowned by a cupola in each corner, each forming the roof of a feature boardroom office below. The huge clock towers either side of the building mirror this pattern, with a ‘mini’ cupola on each of their four corners. All 12 cupolas direct the eye upwards to the summit of the building where a verdigris Liver Bird perches eternally on each of the final, central cupolas.

With Cunard, one of Liverpool’s greatest companies, celebrating its 175th anniversary this year, it was time to refurbish the distinctive cupolas of one of its most famous buildings in the world in time for a celebratory flotilla. Kemper System’s 1K-PUR cold liquid-applied waterproofing system was selected to complete the challenging scheme.

Limited Access

The cupolas are of concrete construction and have been protected by various waterproofing systems over the years but water ingress was becoming an issue and in some areas the concrete was failing and had to be repaired to return the surface to its original domed shape.

Roofing contractor, K Pendlebury & Sons Ltd were appointed by main contractor Quadriga Ltd, specialist restoration contractors, to carry out the challenging task of working at height on the roofs in an exposed waterfront location.

Comments Neilan Symondson from Pendlebury: “Scaffolding was erected on a small area of the roof at a time and an upgrade to localised areas of the roof beneath each cupola, along with a larger stretch on the Strand elevation, was incorporated into the scheme to capitalise on the accessibility we had to those locations while the scaffolding was in place.

“For these areas, we installed an inverted insulated roof build up, using Kemper System’s V210 cold applied waterproofing system to waterproof the substrate, followed by insulation and then paving.

“The Kemperol 1K-PUR we used for the cupolas works in the same way, with a combination of liquid resin and reinforcement fleece, but it is much more viscous than the Kemperol V210, making it more suitable for the cupolas’ vertical surfaces.”

SpeKemper2cialist Approach

Pendlebury selected the Kemperol 1K-PUR systems following trials carried out prior to commencing the project to ascertain the best approach to delivering the project with the level of finish required by the building’s management company, CBRE, and English Heritage while managing the time constraints of the project.

The challenging weather conditions of the building’s waterfront location and the need to identify a system that was suitable for the varying surfaces on and around the cupolas also influenced the specification. The method of fleece application and ease of use of the Kemperol system was ideally suited to meeting these criteria on a scheme that involved working up to 14 storeys high.

The installation team began the restoration of each cupola by repairing each concrete structure using Kemper System’s primer mixed with quartz sand to make a mortar that could be used to build up the eroded areas.

The large cupolas have a two metre high vertical surface before the structure starts to curve and gradually become flat over the top. Pendlebury used a combination of Kemper System’s EP5 primer and quartz sand to create a key on the substrate before applying the liquid Kemperol 1K-PUR resin with brushes and rollers. Kemper System’s 120g reinforcement fleece, cut to size and shape on site, was then laid onto the wet resin. Finally, further resin was immediately applied over the top to allow complete saturation of the reinforcement fleece in a single wet-on-wet process to provide a totally seamless, monolithic membrane.

For the larger cupolas, the scheme also involved scroll features and termination details and the installation team also painstaking applied the system around the solid granite mini scroll features that surround each of the smaller cupolas.

CBRE’s Simon Hepple adds: “In terms of surface area, the Royal Liver Building scheme was not large but is was extremely challenging and required both a specialist approach and careful product selection.

“Kemper System’s Kemperol 1K-PUR was ideal for this unusual project.”
