Big Foot Systems Shortlisted in H&V News Awards for Coca-Cola European Partners GB Project

rooftop support solutions

Sussex-based Big Foot Systems, which leads the way in non-penetrative rooftop support solutions for building services and safe access equipment, is delighted to announce that is has been shortlisted in the prestigious H&V News Awards for its project with Coca-Cola European Partners Great Britain (CCEP GB). Named as a finalist in the ‘Retrofit Project of the Year’ category, Big Foot supplied a custom Safe Access solution and HD Beams rooftop plant support to a project at CCEP GB’s Wakefield manufacturing plant.

The H&V News Awards’ judges reported that they received a high number and quality of entries this year and so making it onto the shortlist is a fantastic achievement. Big Foot Systems will now present their entry directly to the judges in March. The winners will then be announced at the esteemed H&V News Awards on Thursday 20th April 2017 at the Grosvenor House Hotel on Park Lane, London.

We are thrilled to have been shortlisted in such prestigious awards on such a high profile project. It was a complex project at what is the largest soft drinks manufacturing plant, by volume, in Europe” explains Sam Birch, Big Foot Systems’ Product Manager. “We were able to provided the preferred solution whilst ensuring minimal disruption to the Wakefield manufacturing plant.”

CCEP GB wanted to increase the production hall cooling ventilation capacity by adding two new air handling units to the existing lightweight standing seam roof. The project needed to ensure minimal disruption to operations during the new installation and reduce the risk of a leaking roof above a facility capable of producing 6,000 cans of soft drink and up to 2,200 bottles every minute.

Having previously worked with Big Foot Systems, the CCEP GB consultant on the project suggested the possibility of using Big Foot to provide a plant and service support strategy which would eliminate the need to penetrate the roof.

The lightweight roof construction posed an additional challenge for the project, but one that Big Foot Solutions met. The Big Foot technical team worked collaboratively with HE Barnes, the contractor for the project, and their structural engineer across many months. Big Foot’s technical team was able to propose several options for consideration, leading to a fully-developed solution using their HD Beam product to span the main rafters and the purlins, while taking the load back to the main rafters. The solution also provided safe access for maintenance of the newly installed AHUs.

To assist the smooth installation, Big Foot’s Technical Team carried out several site surveys. The engineered design and technical support by Big Foot allowed HE Barnes to provide a detailed lifting plan and method statement to the CCEP GB Health and Safety team. Big Foot’s Technical Team was also on site for the frame erection and AHU crane lift to the roof, utilising a 250 tonne crane with a 60-metre reach. Thanks to meticulous planning and preparation, the full installation was carried out seamlessly within five hours of the crane being set up. Big Foot therefore provided the best solution with minimal disruption to CCEP GB’s Wakefield manufacturing plant.

An HD Beam is a non-penetrative support frame for chillers, AHUs, packaged plant, generators, pipes and steels. It is a robust but flexible solution where space may be limited, or there is a requirement to position directly over existing structural roof steels. Weight is then evenly distributed across the specified quantity of HD Beams. It is also height adjustable to maintain a level system on roof falls up to 5 degrees.

The Big Foot Safe Access range is designed to allow a secure route for service engineers and other trades to gain access to plant and for managing the flow of other personnel. Offering secure and easy access to roof-top services, Big Foot will survey and design custom Safe Access systems tailored specifically to meet individual design parameters.

Cembrit BBA certified slates rise to the challenge

Roof Slates

The flexibility, aesthetically pleasing and easy to install attributes of Cembrit Jutland fibre cement slates have been illustrated on a newly built apartment block in Poole, as the slates have provided a stunning finish to what was a challenging roof.

Inverclyde House is a newly built three storey development that consists of 18 two and three bedroom flats. Located on the south coast of England in Poole, the apartments are central to schools, hospitals and the town centre.

Bournemouth-based contractor, AST Roofing installed 7,000 600x300mm blue/black Cembrit Jutland fibre cement slates, covering approximately 450m2. The roof on this project was interesting, yet challenging for the contractor, as it included a number of pitches and a turret. This unique roof demanded a high quality roofing product that would be easy to handle, install and wouldn’t require any sorting or grading.

“The roof design posed a major challenge, but we were confident that our choice in product would allow us to deliver the desired result,” says Paul Stevens, Managing Director of AST Roofing. “We had to take great care in achieving a neat mitred hip detail, and Cembrit Jutland slates allowed us to do so. The consistency in quality with these slates was impressive. Not only does it mean that the product is easy to work with, but it provides a smooth finish that can’t be achieved with other roofing materials.”

Jutland slates feature a smooth surface and are pre-holed, square edged and lightweight. They do not need to be graded and sorted like natural slates. These qualities combine to make them easy to handle and install and an ideal solution for a fast-track construction environment. Jutland slates are available in Graphite, Blue/Black, Russet and Autumn Brown colours.

Jutland slates are manufactured to the highest European standards using Portland cement together with a formulation of superior blended synthetic and cellulose fibres. Cembrit fibre cement slates are finished with a high quality, semi-matt acrylic coloured coating to the face and edges and a tinted, high-performance binder to the back face. The slates are manufactured in accordance with a quality assurance system to ISO 9001 and to the requirements of BS EN 492:2012 product specification for fibre cement slates and their fittings. Jutland slates have been awarded the BBA Certificate No. 03/4041.

Cembrit A/A+- rated fibre cement slates can contribute to achieving an environmentally outstanding building. The five variations (Jutland, Zeeland, Westerland, Moorland and Diamond) allow designers to achieve the highest ratings for roof specifications and are currently the only fibre cement slate certificated.

Kemper System Showcases Complete Sustainable Roofing Solutions at Ecobuild 2017

EcxobuildKEMPER SYSTEM manufacture KEMPEROL® liquid roofing and waterproofing systems for the long-term protection of roofs buildings and critical structures.  At Ecobuild 2017, our roofing products continue to address the question: What is sustainability?
kemperol

Our proposition at Ecobuild is all about sustainability with KEMPEROL® 2K-PUR cold applied liquid waterproofing leading the way.

When we talk about roofing systems, their relative merits and sustainability, we need to understand what sustainability means: 

The capacity to endure, with the quality of not being harmful to the environment or depleting natural resources and thereby supporting long term ecological balance. 

So how do we fit the bill?

The Resin

80% of the resins in KEMPEROL® 2K-PUR are derived from the seeds of the tropical castor plant (ricinus communis) a sustainable resource that for every kilogram of castor oil produced in place of a petroleum-based polyol, there is a reduction of nearly 3.5 kilograms of Carbon Dioxide (CO2) from the atmosphere. A cradle-to-gate study commissioned by the Department of Energy (DOE) reported that there are essentially zero net greenhouse gas emissions from the production of castor oil.  Added to that the reinforcement fleece we use contains a 25% recycled plastic bottle content.  Kemper System is fully committed to the conservation of natural resources and are part of the chemical industry’s unique global initiative – ‘Responsible Care’.

The Application

Substrate conservation is a key element in sustainability.  When our approved contractors carry out refurbishment work or upgrade the insulation on an existing roof, the KEMPEROL® resin is usually laid directly onto the substrate or utilises the failed membrane as a vapour control layer as part of our Stratex warm roof system build up.  This avoids the costly removal of the failed roof substrate and transport off site to become landfill.  This can also have the added benefit of reducing the duration and cost of your project.

The Performance

None of the above would mean anything without great performance.  KEMPEROL® 2K-PUR is not only solvent-free and odourless, it has proven performance in use with a BBA certified performance life in-excess-of 25 years.  It is also inherently root resistant making it ideal for green roof projects.

Responsibly sourced, environmentally friendly in application and long term performance; produced by a company that conforms to recognised environmental standards.  What more could you want from a roofing product?

Guardrail Installation Horrors

Article by Terry Creed, Technical Sales Consultant, Safesite Ltd

roof edge protection

We’ve written in the past about the importance of competency, especially when it comes to fall protection equipment.  I spend a lot of time on roofs and unfortunately come across some shocking work which illustrates what happens when price is chosen over competency.

The following are the latest batch of horrors I’ve seen when out and about on site.

roof safety

This system is installed so poorly it’s quite unbelievable that someone could leave it that way!  The guardrail is too low, weights and feet are in the wrong position, extremely unstable, grub screws loose or missing, uneven…I could go on…..

roof safety

Poor guardrail installation – no mid rail, a fitting is missing completely and the hot vent flue has damaged the rail. And when you look at the installation from the other side, it gets worse.  The photograph below shows that single fixing has been used into the masonry.

Safesite

This is definitely not something we would recommend as the fixings can work loose over time.

Kemper System provides solution for Chester Zoo’s Monsoon Forest

Kemperol

Waterproofing specialist, Kemper System, has provided the roofing solution for a hot and humid environment in the heart of leafy Cheshire at Chester Zoo’s £40m ‘Islands’ development.

The company’s solvent-free Kemperol 2K-PUR cold liquid-applied waterproofing membrane has been used for the roof of the ‘Tree House’, which will form a covered walkway for visitors under a giant polymer dome – called Monsoon Forest. 

Designed by Dan Pearlman, the exhibit forms part of the largest zoo development in UK history,Islands, comprising six South East Asian island environments which visitors can explore on foot or by boat to discover native plants and wildlife from the region.

Within Islands is Monsoon Forest which will be home to numerous species including Sulawesi macaques and orangutans, and the tree house – which mimics a field research centre – will enable visitors to walk through the enclosure along a raised walkway.

Roofing contractor, K. Pendlebury Roofing, met with the client at the zoo to discuss specification for the job, which had to take into account the habitat’s changing climate, the water mist that is used to create humidity and, the behaviour of the animals.

Explains Neilan Symondson from K. Pendlebury Roofing: “There is adjacent netting along the side of the tree house roof and the orangutans can move freely within their enclosure, which means that they could throw things onto the roof, pick at the surface with their fingers or even urinate on it.

Kemperol 2K-PUR provided a robust, flexible solution that will not crack or soften at high temperatures and will provide excellent resistance to humidity, puncturing and uric acid; and roughly 80% of the resins in the Kemperol 2K-PUR are obtained from the seeds of the tropical castor plant which is a renewable resource.”

The walkway with its shaped surfaces and the high temperatures proved challenging whilst working on the project. K. Pendlebury Roofing taped the seams of the 200m2 plywood surface to prevent any resin from seeping through the joints during the application process.

Following application of a primer mixed with quartz sand to provide a key, the cold-liquid Kemperol 2K-PUR resin was then applied directly onto the roof. The installation team then laid Kemper System’s 165gsm flexible reinforcement fleece, which is cut to size and shape on site, directly into the wet resin, using rollers to remove any creases or air bubbles before immediately applying more resin to fully saturate the fleece. The system was applied in a single wet-on-wet process and allowed to cure, providing a seamless, monolithic membrane that bonds directly to the substrate, which is permanently elastic and cannot delaminate.

“Kemperol 2K-PUR is an environmentally responsible waterproofing solution that helps us deliver that remit while ensuring a safe and durable environment for both visitors and the orangutans.”

Redland courts success with Cambrian Slate

When the team at Forster Roofing first realised that the Crown Office and Procurator Fiscal Service’s building in Glasgow was the ideal showcase for its integrated roofing and solar service, they also realised that Redland’s lightweight Cambrian Slates were perfect for the project.

The commission to install solar panels on a sensitive, fully operational building in central Glasgow was a tall order in itself but an inspection of the existing slate-composite roof showed that it had less than 10 years life left. So, rather than just install solar panels, the project was expanded to incorporate the renewal of the entire 1,800m² roof covering.  And, because the roof structure was not designed to withstand the weight of natural slate, the roof was stripped and 25,000 Redland Cambrian Slates were fitted.

Steve Scott, Managing Director of Forster Roofing Services, says that the Cambrian Slate – in Slate Grey – matched the previous roof colour, complemented the existing roofscape and was also easy to fix, with confidence that it would not fail over its lifespan.

“The existing roof covering was failing and the client was looking for a robust replacement,” he says. “Redland’s Cambrian Slate fitted the remit perfectly, providing a very secure covering whilst enhancing the slate appearance of the roof. The Cambrian’s sleek finish aligned perfectly with the integrated solar PV on the roof.”

The company also installed a total of 96 270Wp panels across the two most suitable roof slopes. Now, the clean, self-generated solar energy is providing power to the offices and helping to reduce the carbon footprint of the building.

Made from over 60% recycled Welsh slate, Cambrian captures all the beauty and character of natural slate and provides outstanding aesthetics, performance and installed-cost benefits.

Redland Cambrian Slates are designed with a unique three-point fixing, making them secure on even the most exposed sites. Manufactured to be lightweight with a thin leading edge and surface patterning taken from impressions of real natural slates, and proven on pitches as low as 15°, Redland Cambrian Slates are suitable for a wide range of projects. When installed with recommended fixings under the Redland SpecMaster service, the whole roof is backed by a 15-Year weathertightness, durability and design liability guarantee.

Three colours are available: Heather, Langdale Green and Slate Grey – with Slate Grey also being available in a pre-weathered finish. Find out more about Cambrian and order a free sample at www.redland.co.uk/cambrian

ECEX overcomes university challenge

access safety

ECEX has successfully solved a roof safety and access problem for the University of Oxford by custom-fabricating and installing a galvanised steel sub-frame and non-slip grating designed to provide consistent, level and safe access to rooftop HVAC equipment.

Access across the roof of a complex of laboratory buildings at the university was obstructed by the pipework, cables and supports serving extraction and HVAC units, including chillers and condensers.

This caused a series of significant trip hazards to employees working on the rooftop, so the University’s engineering team called in an ECEX specialist to survey the area and improve access. The University was already familiar with the company and impressed by its work because ECEX has previously supplied and installed Air Intake Screens widely across the university’s 300-plus building estate.

ECEX uses the hierarchy of control measures determined by the Health & Safety Executive to decide the optimum solution in each specific case. John Grenville, managing director, explained: “In other words, the ultimate measure is to remove the hazard completely if this is practical. If not, the next measure down is to use collective fall protection such as guard railing so that someone without specialised training can move around the roof safely. The next level down would be the use of personal protective equipment such as a harness, and so on.”

ECEX’s means of access for the University of Oxford project was through occupied parts of the building so the company installed its gantry system out of hours to avoid disruption.

ECEX surveys, designs, manufactures and installs bespoke and off-the-shelf access safety solutions, including:

  • Walkways and step-overs
  • Access ladders and platforms
  • Guardrail and edge protection
  • Stairs
  • Mesh security caging
  • Other fabricated metalwork

Redland’s BCP pitched roof training is just the ticket

PITCHED ROOFING TRAINING

Roofers lacking formal qualifications can now enjoy CITB-funded training thanks to Redland’s accreditation as an approved provider of the Basic Competency Programme (BCP) for pitched roofing.

The BCP certificate – when combined with a Working at Heights CSCS Health & Safety Test pass – entitles both apprentices and ‘old hands’ to apply for the three-year Red ‘Experienced Worker’ CSCS ‘ticket’, allowing them to work on site while looking towards the next level of qualification.

The main objective of the BCP is to support roofers without either a full competency or an official roofing qualification in obtaining one; and help them to convert their green CSCS cards to the Blue Skilled Worker CSCS version. It will also help those in other trades, perhaps already holding higher level CSCS cards, to change sector or add to their skill sets. The BCP is endorsed by the CITB, the NFRC CompetentRoofer scheme and CSCS.

The two-day course covers areas such as pitch, scale, orientation, setting out, constants, estimating, understanding BS 5534; plus practical ‘how to’ sessions on the installation of roofing systems, both single lap interlocking and double lap plain tile and slate. The course is delivered from Redland’s National Training Centre based just outside Cirencester, Gloucestershire.

Heavily subsidised by Redland and the CITB, the course costs only £150 for both the training and certification. A CITB training grant may also be available to qualifying companies, bringing the total cost of the BCP certificate down to just £50.

Mat Woodyatt, technical training manager at Redland, said: “Obviously it’s an honour for Redland to be recognised as the only one currently capable of meeting BCP certification training demands for pitched roofing. But beyond that, it’s fantastic for us to be involved with bringing through the next generation of roofers, as well as setting older hands off on the qualification pathway. It’s great for us, great for them and great for the industry”.

Fast construction with prefabricated wood elements

Kerto® LVL roof panels

Using wood elements allows faster building turnaround. This leads to more profitable construction projects and shorter investment payback times. The pace of construction is kept at the desired level, because prefabrication reduces some of the most common risks at construction sites.

Faster construction with wood elements

Utilizing prefabricated wood elements is a surprisingly fast option for on-site construction. For example, up to 1500 m2 of Kerto® LVL (Laminated Veneer Lumber) roof panels can be assembled within a single working day.

Kerto® LVL roof panels

“An example of rapid building is in the construction of the headquarters of the Diesel-Benelux Company in Amsterdam. An extremely tight building schedule of only nine months resulted in choosing Kerto LVL roof panels – under which the rest of the construction work could be finished in time,” project subcontractor in charge of the wood construction, Lambert van den Bosch from Heko Spanten, mentions.

Clever on-site weather protection with no additional costs

One of the most important construction phases is to get the on-site protection done quickly to eliminate weather-related risks. Today, the alternatives for on-site weather protection include applying fast construction methods, such as prefabrication or building under a tent.

Prefabricated wood elements shield the building site beneath, providing protection that’s superior to temporary options – especially when it comes to snow loads and heavy winds.

Quick protection for construction site with Kerto® LVL

“For example, erecting Kerto LVL roof elements used at the logistic centre of DB Schenker, Finland provided a roof over the entire building in just 15 days. This is the same amount of time that erecting a temporary tent would have required. Using prefabricated roof panels ensured that the rest of the work could be completed in a protected environment and without additional costs for temporary protection,” says Matti Kuittinen, architect and researcher from Aalto University.

Minimizing the risk of accidents

When the construction work takes place in controlled indoor conditions at the prefabrication plant, there is less risk of accidents and consequent delays at the building site. This is because some of the dangerous on-site phases are no longer needed.

“Assembling ready-made wood elements can replace the potentially more dangerous process of having to build a roof from beams, panels and bitumen at the heights of an unfinished building. On-site accidents are of course not frequent, but every single one of them should be avoided,” van den Bosch concludes.

Prefabrication “pays off” at the construction site

According to construction professionals interviewed by McGraw-Hill Construction, nearly 70% of projects that used prefabricated elements had shorter schedules and 65% had decreased budgets1. In addition to faster building projects leading to faster revenue, there is also other benefits that become apparent at the construction site.

Prefabrication pays off at the construction site

“Utilizing prefabricated wood elements can help in significantly reducing other inconveniences such as unloading building materials in the neighbourhood, as well as the amount of on-site waste and the need to transport it,” Kuittinen adds.

Quick facts

·     Prefabrication pays off: 70% of projects had shorter schedules and 65% decreased budgets.

·     Up to 1500 m2 of Kerto® LVL roof panels can be assembled in 1 working day.

·     At the logistic centre of DB Schenker, Finland, Kerto LVL roof elements provided a roof over the building in just 15 days.

·     Kerto LVL roof panels helped the Diesel-Benelux Company to keep to their tight building schedule of 9 months.

Sika Sarnafil branches out with unique garden room project

In possibly the only building of its kind in the UK, Sika Sarnafil single ply membrane has been used to waterproof a garden room with a live tree growing through it.

Hackney-based architect, Andrew Leckenby, specialises in working with private clients to improve their homes. But when it came to extending his family home, Andrew became his own client. Living in an urban area meant imagination was required to increase his living area.

SINGLE-PLY MEMBRANE

Deciding to make the most of his home’s outdoor space, Andrew settled on a garden room. However, the rear of the garden contained a beautiful false acacia tree, which he did not want to remove. Thinking outside the box, Andrew drew up plans for a room that would incorporate the tree, making it the focal point of the space.

Andrew explained: “There are countless examples of trees being integrated with architecture – but these are generally found in countries where it doesn’t rain quite as much! To be able to achieve the same effect in the UK, we needed a roofing membrane that was flexible enough to allow the tree to sway and grow, as well as being durable enough to keep the building watertight.”

Andrew had specified Sika Sarnafil on many extensive commercial projects during his career working with larger architectural practices, so knew that the product would meet his requirements.

SINGLE-PLY MEMBRANE

“Faced with a challenging roof design, I instantly thought of Sika Sarnafil. As the industry leading single ply membrane, after decades of specifying it for corporate clients, I was confident that I could trust its quality and durability. In addition, Sarnafil’s Registered Contractor scheme allowed me to identify an installer that had the training and experience to do the job – essential for detailing of this nature.”

The finished article is a striking, yet homely multi-functional space, used as a garden room that extends the summer season, a home office – and not to mention a unique sleepover location for Andrew’s son.

SINGLE-PLY MEMBRANE

A member of the Sika Sarnafil technical team inspected the project once complete and awarded a 15 year guarantee on the roof. The low maintenance membrane means Andrew only has to check the waterproofing once a year to ensure the detailing around the tree is still sound. A small price to pay, says Andrew, for such a fantastic family space.
