Leaders from around the world have gathered in New York this month for the annual UN General Assembly. As well as universal topical debates, such as the continuing rollout of COVID-19 vaccinations and boosters and the Taliban’s takeover of Afghanistan, climate change is another matter that has come to the fore. Ahead of the 2021 United Nations Climate Change Conference (COP26) this November, our very own Prime Minister, Boris Johnson, has spoken up and declared that it is time that we all “grow up” and tackle climate change. At the summit, the PM asked countries “to commit to substantial emission reductions” and – in Johnson’s typical jovial fashion – light-heartedly likened the ability of being green with a Muppet melody, saying: “When Kermit, the Frog, sang ‘It’s Not Easy Bein’ Green’, I want you to know he was wrong.” In this month’s edition, we look at some of the social media activity that’s been occurring during this year’s UN General Assembly from official bodies. Turn to page 07 to read some of the updates. As we all know, being ‘green’ means making changes. In the construction industry, there are many procedures that need to adapt. From how building materials are specified and the logistics to manufacturing building materials themselves and onsite construction, countless processes need overhauling. In our October issue, we make a step forward by looking at a greener method of climate control – radiant cooling. In this article, Greg Cooper, Managing Director at Radiana, discusses the benefits of radiant ceiling systems. Turn to page 22 to read the full article. I hope you enjoy this issue.

NE W S I N BR I E F: BANK BACKING HELPS DEVELOPER COMPLETE LUXURY LAKESIDE SCHEME

Marden Homes has secured a £17m loan from Shawbrook Bank to help complete a unique, luxury lakeside scheme at The Channels development in Chelmsford, Essex. The developer turned to Shawbrook Bank midway through construction at The Lakes to secure the development finance required to help take the project through its final stages. Construction at the £28m scheme is split into two phases, with the seven houses now on track to complete by December 2021, and the 20 apartments to complete by December 2022. Its development comes as the pandemic prompts housebuyers to seek properties with more surrounding space, with luxury finishes and the ability to work from home.

BTR SCHEME LEADS THE WAY FOR ENVIROMENTALLYFRIENDLY LIVING

Sustainable living is topping the list of priorities when searching for a new home with 92% of UK adults citing a sustainable community as important when deciding where to live. As well as the greener footprint and feeling good about where you live, eco-friendly living can offer lower utility costs. One residential development which is leading the way for ecofriendly apartment living is The Keel in Liverpool’s city centre.

ARCHITECTIN PROFILE

Ben McKenna started out studying interior architecture at Brighton. From there, he joined a small practice that worked in sensitive locations in rural Kent and Sussex. Ben’s work here was focused on listed building alterations and rural housing. With a desire to expand on what he’d learnt working at a small practice, Ben joined Conran and Partners to work largely on estate regeneration and residential projects in London and the South East. Having recently joined DMWR Architects, Ben talks to us about his time at Conran and Partners and runs through a few of his favourite designs. DMWR ARCHITECTS

Please tell us a bit about your career background. The skills I learnt, being very hands-on with the design and construction process after I’d left university, served me well at Conran and Partners. I was able to bring the same attention to detail that I applied to a rural extension to a large-scale housing regeneration. An ethos I’ve lived and breathed over the past decade is that good design should be accessible to all, and I am passionate about well-designed, Having stayed at Conran o f r 12 years, I’m excited to have recently joined DMWR to work with their extensive range of clients and to expand the residential side of the business. Have you always wanted to pursue a career in architecture? Yes. Since I was seven and sat drawing my mum’s house all afternoon from across the road – I knew then this was what I wanted to do. Who has been your greatest influence and source of inspiration? There have been loads, but to mention one, it would have to be Yves Saint Laurent o f r his determination and dedication to his craft (although, I don’t like the polo shirts!). Alright, maybe two; I can’t help mentioning Damien Hirst o f r his ability to merge business and art.

CAGBALETE SAND CLUSTERS, CARLO CALMA CONSULTANCY INC.

CLUSTERS OF CREATIVITY Cagbalete Sand Clusters creates a new sustainable typology for eco-tourism, one that uplifts the local culture and revolves around farming and fishery. CARLO CALMA CONSULTANCY INC.

esired to create a community building and nurturing ecology for its surroundings, Cagbalete Sand Clusters is a dynamic space for both its inhabitants and visiting tourists. This intermingling is vital to the Filipinos as an archipelagic country of 7641 islands, each with its own distinct cultural and natural identities. The design explores the inherent values of locality and sense of place, but through more ethical means of development. The project integrates its locale’s programmatic and cultural context into the architecture, which is essentially a unit system – a pre-fabricated set of parts that can grow horizontally or vertically. FC&A – OCTOBER – 2021

The client wanted to create farm lots in a 3.8-hectare property in Cagbalete Island, Quezon province. With a radial site development, a hyperbolic cluster unit system is created that was largely inspired by corals, given the location’s rich marine life and biodiversity. The resulting structure is a mixed-use development: a private family home and a farm-to-table restaurant that focuses on the use of endemic plant species and seasonal mud crab farming. One of the considerations is that mud crab farming can help prevent soil erosion and that the activity can also help protect the existing biodynamic mangroves in the area. The team also introduced local hapa nets into the 12

design as a kind of membrane that gets mixed with local sand, soil and mud, resulting in a new and localised patina, a biophilic membrane that creates an interesting footprint with the hyperbolic possibilities it offers. The hapa nets also function as a ‘veil’ over the structure and a translucent skin that masks sun and rain, but also as informal sleeping areas (mosquito beds) for afternoon siestas. They have elevated the humble hapa net into something beyond its utilitarian origins; it is now both part of the structure’s construction membrane, a tool for food production, and a web that facilitates the daily activities of the structure’s inhabitants, enmeshing time, culture and space.

The project envisions a farmleisure community that is selfsustaining, where electricity is produced from bespoke solar umbrella pods, and where the spaces largely utilise natural ventilation. It aims to blur the boundaries between what is natural and artificial in this structure, opening it to transformation throughout different seasons, rain or shine. A wellness grotto with salt water is also present, together with mud and dipping pools, where a sensory experience awaits its users. At night, the development shines and transforms into a glowing, plankton-like space with multi-level galleries, performance spaces and lighthouse functionality. 13

Cagbalete Sand Clusters won the ‘Food’ category of the WAFX Awards this year, and the project is also a finalist in the ‘Experimental’ category of the World Architecture Festival, to be held this December in Lisbon, Portugal.

NORDIC COPPER FOREVER For one New Zealand family, ‘forever home’ meant just that when they and their architect chose Nordic Copper for the external skin of their new house on the foreshore of Cass Bay, near Christchurch. The house’s organic design is an exemplar for copper in contemporary architecture while celebrating a strong tradition of craftsmanship. AURUBIS

aving transformed their previous house over 20 years, Aaron Green and his family turned their attention to creating a very personal new home to make the most of a challenging plot with a stunning sea-front location. Close collaboration between the family and their architect, Michael O’Sullivan of Bull O’Sullivan Architecture, characterised the design process. Without a detailed brief, careful consideration of what the whole family wanted from their new home developed a unique design defined by its natural wave-like plan, spatial complexity and organic form. The main living level is set into the sloping site, before emerging, reaching out towards the sea and elevating to take in expansive panoramic views towards Quail Island. The curvilinear plan – with a æuidity inæuenced by the architect’s watercolour sketch design methodology – wraps around the plot to maximise

accommodation, punctuated by a mullioned, semi-circular stair tower. The building’s organic form generates double-height living areas and distinctive spaces, with extensive timber surfaces adding warmth. Discrete views of the surrounding hills, sky and coastline are curated and perfectly framed with distinctive rooæights and windows.

Although initially conceived as an entirely cedar-clad building, this material was considered to be too complicated and costly, and alternative solutions were sought. Architect Michael O’Sullivan comprehensively explored with his clients how Nordic Standard copper would naturally change and develop over decades in this specific

location, using his trademark watercolour sketches and copper samples – including one from the original roof of Christchurch Town Hall, salvaged following the 2011 earthquake. Manybenets ofcopperwere identied, including lighter weight requiring less steel structure, durability with no maintenance and a naturally developing surface appearance. As Aaron comments: “The copper will become more beautiful with time and an asset that we never have to touch again. It ts inwith ouraim to create a building that will last for literally hundreds of years.” Copper is a natural element, one of the first metals used by man and one of our oldest building materials, with a fundamental appeal. Aaron adds: “Copper is something that reminds me a lot of my childhood.

Exemplary detailing and workmanship

Nordic Standard is ideally suited to this dramatic copper carapace emerging out of the seashore, providing a weathertight external skin that can be adapted to all the building’s geometric complexities. With detailing and installation, again close collaboration was key and copper details were agreed on site between the architect and specialist fabricator/installer The ArchitecturalRoong Company(TARC). Nordic Standard 0.7mm-thick ‘mill finish’ copper was used throughout, using a combination of modern long-strip technology and hand-worked traditional details ranging from copper louvres to a rainwater hopper with lipped weir overflow. Elements such as the cave-like entrance, with subtly inclined walls clad inside and out in copper, are a showcase of craftsmanship and testament to TARC’s exceptional care in execution. TARC’s Jordan Ross comments: “This project was a massive challenge but the most satisfying thing that we’ve done.”

Within a few days of exposure to the atmosphere, a copper surface begins to oxidise, changing from the ‘bright’ mill finish to a chestnut brown, which gradually darkens to a chocolate brown. Over the years, with continued weathering, the distinctive green/blue patina seen on older roofs can eventually result. This is influenced by specific local conditions and particularly likely in exposed locations, with the patina taking on more of a blue hue in marine

COMMUNITY CENTRE GROSSWEIKERSDORF, SMARTVOLL

EVERYTHING UNDER ONE ROOF ‘The doughnut effect’ – a familiar occurrence in Austrian communities. It slowly draws traffic away from town centres via local suppliers on the periphery, leaving the centre to die out. This new community centre, however, is fighting back against this doughnut effect. Developed out of the row of houses at the main square, this new heart of the village opens up as an inviting and welcoming gesture. Citizens and visitors alike not only feel welcome but are also encouraged to make use of the building. A strong symmetry to the main square adds gravitas and meaning to the self-evident gathering place. The rotation of the structure and the resulting opening of the site, along with the orientation of the main entrance onto the main square, expresses an ultimate gesture of welcome, encouraging visitors to explore and discover. SMARTVOLL

he narrow ‘Winzergassen’ (Winegrowers’ lanes) offered by the frequent rhythmic shifting of the building structure provide charming inner courtyard environments, as well as space for developing a variety of activities. The new community centre is functionally and structurally divided into three parts. Oriented to the main square at the front is the town hall. The second part of the FC&A – OCTOBER – 2021

building contains a clubhouse, providing flexible space for a variety of traditions and activities. Finally, in the eastern part of the building, a medical centre provides space for up to five doctors operating within a group practice. The building is segmented into several parts that are shifted to each other. On the one hand, the building is sliced into bites that are compatible with the local scale, while

on the other hand, it clearly depicts the spatial program and functions. The entrances for the clubhouse and the medical centre are also created in the offset areas. This offer is supplemented by the programme’s flexibility, which provides citizens with a variety of options for using the building for themselves, whether in the clubhouse, via the outdoor areas, or in public zones in the city hall itself. The 16

integrated medical centre and a potential area at the rear of the property also provide an increase in frequency. The new community centre is proposed to play a central role in village activities. It is the antithesis to a mere administrative building and is interpreted as a built manifestation of a lively and active village centre.

LIZ SLACK IS A SENIOR PR ACCOUNT MANAGER AT HARRIS CREATIVE. A FULL-SERVICE CONSTRUCTION MARKETING AGENCY OFFERING GRAPHIC DESIGN, PUBLIC RELATIONS, WEB DESIGN AND DEVELOPMENT, SOCIAL MEDIA MANAGEMENT, PHOTOGRAPHY AND VIDEOGRAPHY, HARRIS CREATIVE IS CELEBRATING ITS 35TH ANNIVERSARY THIS YEAR.

WHY GOOD NEWS IS WELL WORTH SHOUTING ABOUT Everyone loves good news. That’s true at any time but given the events and challenges of the last 18 months, the appetite for good news is even greater than ever before. Liz Slack from specialist construction marketing agency, Harris Creative, explains why it’s a great idea to include positive social and corporate stories as part of your PR and marketing strategy alongside product and project updates, and how to make sure you’re communicating it in the right way to appeal directly to your customers, staff and other stakeholders. HARRIS CREATIVE

What is CSR?

First things first – what is CSR, or ‘Corporate and Social Responsibility’ to give it its full name, and why should you care about it? In essence, CSR is the umbrella term for the different initiatives you can undertake as a company to give something back to the communities you serve, your staff or the environment around you. It can range from small, one-off activities arranged by one or two staff to large-scale, all-encompassing campaigns that involve the whole company and potentially even your supply chain too. All have their role to play, and it’s about more than that warm fuzzy feeling you might get from doing something good for others. Ensuring that CSR activity is a key part of both your business objectives and marketing goals brings with it real business benefits both now and in the future. And here’s why.

What benefits does effective and considered CSR bring?

When you invest in CSR activities as a way to make a difference to the world around you, no matter how big or small this commitment may be, it shows the values FC&A – OCTOBER – 2021

that are important to you as a company. If you can demonstrate to your clients that you are not solely driven by increasing profit margins, this can create positive perceptions of your company – over and above the quality of products and services you offer. Actions speak louder than words, so if you want to show that you’re a company that cares about sustainability, for example, then committing to invest time, money or resources into protecting the environment is a tangible way to highlight your good intentions. Highlighting company values through planned CSR activity has also been shown to help with recruitment and staff retention, especially if staff are actively encouraged to participate in activities or suggest initiatives. Company-wide activities of this type are a great way to create an engaged and loyal workforce. Being able to show that you care goes a long way to securing repeat business and also winning new work, whether you’re working within the commercial, public or domestic sectors. Moreover, many organisations within the public sector, in particular, are increasingly keen to see a CSR element included as part of your pitch for work. Getting into the habit of 18

including CSR as part of your day-today corporate activity will put you head and shoulders above your competitors when it is a requirement on a project. Not only that, but if you’re able to work with different parts of your supply chain as well as external organisations on such projects, it gives you the chance to forge new links, which can, in turn, lead to lucrative new business opportunities. And nally, including CS R within your marketing and communications strategy is an excellent way to improve your overall brand awareness within the market – if handled well. Your PR and marketing strategy doesn’t have to remain 100% focused on your products, services and projects to be eective. Including additiona CSR activity into the mix helps cement your name as a memorable brand and provides a platform to talk about your company more generally to your customers.

How can you tell the world about it?

It’s a fine balance to strike to get the tone just right when it comes to talking about all the great CSR projects and activities you’ve completed. You need to be mindful that it doesn’t appear that any CSR activity

VOICE OF THE INDUSTRY

you’ve done was motivated purely by commercial gain but rather because it’s something that is genuinely important to you as a company. And to make sure that you strike the right chord with any CSR activity, it’s vital that you carefully consider your approach in the first instance to make sure it aligns as closely as possible with your overall business objectives and values. Any CSR activity needs to fit within the scope of your business and expertise and ideally should be relevant to the sectors you serve. So long as you’re doing it for the right reasons though; this will come across in your communications and will reflect well on your company as a result. From a practical viewpoint, it’s worth remembering that if you’re working with a charity, organisation or partnering up with another company within your supply chain on a CSR project, that you follow any communications guidelines they’ve set. Joining forces on marketing is a great way to amplify the message and for all involved to reach as wide an audience as possible, so you all benefit from the glow of good news.

EXPLORING CHANGES TO: THE NATIONAL PLANNING POLICY FRAMEWORK (NPPF) Have the recent changes to the national planning policy framework (NPPF) missed an opportunity for a more consistent approach to heritage assets? Richard Harris, Partner at Carter Jonas (Oxford), investigates. CARTER JONAS

RICHARD HARRIS IS A PARTNER AT CARTER JONAS O ( XFORD)

FC&A – OCTOBER – 2021

orking with a number of national clients with extensive heritage portfolios, I regularly experience and hear from clients about a lack of consistency when dealing with conservation issues, even within the same local authority. With precedent being a key part of the planning process, it is interesting to consider what has previously been consented as alteration works to listed buildings, compared to today. Since the introduction of English Heritage’s Conservation Principles Policies and Guidance Note in 2008 and the National Planning Policy Framework, which includes a heritage section, there has been a significant change in how listed building consent applications are addressed. The guidance was brought in partly to address a perceived harm inflicted on listed buildings in the 1960s and the loss of, in some cases, considerable amounts of historic fabric. But there appear to be many differences between the approach taken by conservation officers within urban local authorities and their rural counterparts. There is also a perception that alterations to listed buildings within an urban setting are more straightforward than those in a more rural context. While there is some credence to this, the reality is much more complex, and given the greater scarcity of historical fabric within some urban properties (usually following stripping out and removal and extensive regeneration of the surrounding streetscape), maintained heritage in such buildings is more scarce. Accordingly, they can be treated with undue sensitivity. 20

The approach taken within the English National Parks is generally more stringent than other rural areas, due to a myriad of factors, including the heritage values that the building provides to the wider community and how much of the historical fabric has been retained. These complexities make it extremely difficult to provide consistency in issuing a listed building consent for alterations and repairs. Furthermore, while there is considerable guidance available, each development proposal will be unique, so it is impossible to compare and contrast: it is ultimately very subjective. Often, clients run into difficulties with listed building applications because of a lack of understanding of the history, construction and development of the building and its significance. The recent changes to the NPPF have not included any amendments to the guidance on heritage assets, and given the complexities and unique nature of these buildings and structures, there is unlikely to be a move towards a more consistent approach. This only highlights the need to ensure that a property owner has the right team, with the necessary experience of heritage buildings, in place at an early stage. A sense of pragmatism is also necessary, as it is unlikely that all proposed changes will receive consent and elements of the scheme may need to be reconsidered. Without a significantly strong and well-supported argument, what may have been achieved 20 to 30 years ago is much less likely to be consented today, and there is no guarantee of success.

RADIANA IS A HIDDEN CLIMATE CONTROL SYSTEM

TAKING AN ALTERNATIVE VIEW ON CLIMATE CONTROL WITH RADIANT COOLING SOLUTIONS Greg Cooper, Managing Director at climate control specialist Radiana, discusses the benefits of radiant ceiling systems, including how this technology can improve the health and wellbeing of occupants, while adding a unique selling point to the property. RADIANA

here are many factors to consider when specifying and installing the most beneficial indoor climate system for a property – from meeting Building Regulations, zoning, controls and ensuring occupant comfort – all whilst being kind to the environment. There is a fine balance to strike if every box is going to be ticked, so it’s time to switch up the physics and take a view of things from the ceiling down with radiant cooling. Traditional indoor climate control solutions, such as air conditioning (AC) units, have long been seen as a desirable addition in highend properties – yet these air blasting systems provide a far from luxurious ambience and also fall down when it comes to their environmental credentials. By their very nature, AC units deliver very uneven cooling, often leaving one person feeling chilly as they sit near the airflow – while someone else in the room barely feels the benefit. This constant breeze not FC&A – OCTOBER – 2021

only dehumidifies the air but could also spread virus particles around, especially if recirculated. Air conditioning isn’t a ‘green’ option either, with systems often guzzling energy in order to create cool air and force it out into the room. During this process, warm air is also thrown outside of the building, which then has a detrimental effect on air quality in the external environment too. On the other hand, radiant cooling provides a fresh perspective on indoor climate control and aims to work completely in harmony with nature, rather than against it. So instead of forcing cold air out, radiant cooling works by using cold surfaces to remove the heat radiated from objects within a room. The cold surfaces which remove this heat are plasterboard-style ceiling panels, or tiles, which are cooled by cold water circulating through integral pipework. In turn, these ‘active’ panels create a luxurious ‘3D cooling’ effect.

There’s no chilly breeze or hot/cold spots within a room; they simply work away silently in the background, cooling all the surfaces in the room. Aside from feeling comfortably balanced, the lack of forced air also means that dust and virus particles won’t be circulating in the atmosphere. With so many people now suffering from asthma and allergies, this improved air quality will be welcomed, as it will further increase the health and wellbeing of those enjoying the space. There are also critical installation benefits too, as radiant ceiling panels and tiles are as quick and easy to install as traditional plasterboard. Whereas traditional air conditioning installation requires additional trades on site due to the need to handle ozone-damaging gases, the requirement for hot works and often complicated commissioning. All these installation aspects have the potential to cause delays and disruption to the build and sequencing, something 22

everyone wants to avoid when taking planning everything in at the specification stage. Meeting every specification requirement, radiant systems can be installed into newbuild projects or retrofitted. Depending on the product selected, they can also be completely concealed within the ceiling, creating a more aesthetically-pleasing end result when it comes to the interior finish, especially when compared to often bulky air conditioning units.

FACADES, LOUVRES & RAINSCREEN

A CLEAR PATH TO STRUCTURAL SAFETY WITH GLASS Glass plays an undeniably crucial role in any building, from enhancing views and lighting to creating captivating works of art. However, its purpose often goes beyond merely aesthetics, delivering structural integrity in a wide range of specifications, says Adam Holliday, Senior Engineer at Perega. PEREGA

hether designing glass wall cladding, balustrading or curtain walling, safety is paramount. Fortunately, there are steps you can take when designing a project’s glass elements to ensure their stability and reliability. I’d like to take this opportunity to outline some of those key considerations.

First principles

The first idea that must be kept in mind with any facade is containment. While I would hope it goes without saying, always bear in mind that there shouldn’t be any open voids that someone could fall through or, if there is one, that it’s at such a level it won’t allow for falling through accidentally. Next, the glass should be strong enough to resist any expected loading. Designing for this depends on the material’s use, which tends to be categorised by if the glass is going to be used in a place where people can or cannot congregate, as set out in BS 6180:2011. While residential and typical office use are considered controlled environments where people are unlikely to gather, public areas, such as shopping and retail spaces, are more likely candidates for crowds and as such, tend to have higher design load values given. In both types of areas, you’ll need to consider wind and barrier loading, however, current design advice is that these should be evaluated in tandem where people can congregate. FC&A – OCTOBER – 2021

FACADES, LOUVRES & RAINSCREEN

Testing

Once the glass elements, and their framing, are designed according to the relevant standards and codes, it’s important to check their structural performance prior to installation. Finite element analysis (FEA) software is capable of doing this, taking into account the elements within the structure, and how they will fit together and interact, to simulate how a product will react to real-world forces. This will highlight any potential issues that need to be addressed before moving forward.

Panel selection

Regardless of which type of glass is used, The three primary options for glass laminated panels increase safety through are annealed, heat strengthened or multiple layers: if one leaf goes, the other toughened, with annealed glass being will stay in place.

Useful guidance

Along with BS 6180:2011, here are some other British Standards relevant to designing structural glass: BS 5516-1:2004 and BS 5516-2:2004 BS 6262 (all seven parts) BS EN 12600:2002. Further, the Centre for Window & Cladding Technology (CWCT) is an industry-leading publisher of guidance and standards around facades, glazing, building envelopes and cladding. It’s a rich resource, providing the construction industry with essential knowledge. The Glass and Glazing Federation (GGF) is another excellent source of advice and test data, covering a wide range of systems.

Engineering safety

According to the CWCT, facade failure is the most common cause of failure in new buildings. However, equipped with the knowledge of how to ensure structural safety, the risk of this can be minimised significantly. Along with being aware of the key considerations above, make sure to engage early on with a glass engineering specialist who can provide expert consultation and remove the ‘pane’ from the process.

SPECIFYING THE NEWGENERATION FIRE DOOR Dave Walker, Technical Director of Distinction Doors – a

DISTINCTION DOORS/FDS (FIRE DOOR SYSTEMS)

uring the post-Grenfell investigation, two undamaged flat entrance doors were removed from areas that were not affected by the fire and were subjected to BS 476-22 fire testing. Test results showed that the doors failed at just 15 minutes. The failure was reported to Ministry for Housing Communities and Local Government (MHCLG). Further tests conducted by MHCLG, using doorsets from the same manufacturer removed from existing installations, concluded inconsistent results – anything from 14 to 40 minutes. The tests were carried out with the doorsets opening into the furnace. This inconsistency sparked a thorough investigation of the fire door industry by MHCLG.

that context must be given for the results which represent “only a sample of the market and are only relevant for the specific model of doorset tested from the manufacturers”. More than two years have passed since the GRP composite fire door report was published, and we can assure you that the industry has been proactive in its response. Key areas include third-party certification, traceability and testing.

Tried and tested

At the heart of this overhaul is robust testing. Under ‘Appendix C: Fire doorsets of the latest version of Approved Document B’: “The requirement is for test exposure from each side of the doorset separately”. One GRP composite fire door system supplier has raised the bar, satisfying not just the British Standard (BS 476-22 Fire resistance and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware), but also the more demanding European test method standard BS EN 1634-1. The company subjected 44 doorsets to 22 bi-directional fire tests. The tests were conducted in three countries, using three variations of supporting wall construction – 150mm and 225mm rigid aerated block and flexible steel stud construction. The test specimens included solid and glazed door leaf options, either with or without overhead fanlights, and all doorsets were tested with letterplates, viewers and door closers included. All featured auto-throw locks. Every fire test was filmed. The system achieved an average of 45 minutes of integrity. This level of commitment and robust testing has sent a clear message to the UK construction industry; you can achieve consistent fire resistance, compliance and peace of mind with GRP composite fire doors.

One direction

Prior to the fire at Grenfell Tower, it was accepted practice that fire door testing should be carried out with the door hung so that it opened in – towards the furnace – testing from both sides was not required. Single directional testing was based on the experience of notified bodies and test laboratories fully accredited by the United Kingdom Accreditation Service (UKAS). Opening into the furnace was deemed the most onerous direction, and so if this most onerous side passed, then there was no need to test the other. The Government test programme proved that this assumption (while true in most cases) was flawed.

Catalyst for change

While Annex A of Approved Document B (Fire Safety) allowed for the assessment of the most onerous direction for test, Appendix B (Performance of materials, products and structures) states that the tests be conducted on two doorsets, one hung opening into and one hung opening away from the furnace. The ministry published its findings in 2019. The documents revealed that three quarters of glass-reinforced polyester (GRP) composite fire doors failed furnace tests. It was concluded that there were “performance issues” with GRP composite 30-minute fire doors “across the market”, although it was noted FC&A – OCTOBER – 2021

Third-party certification

Since Grenfell, several GRP composite fire door system houses, and members of the Association of Composite Door Manufacturers, have gained non-mandatory, third-party certification and taken control of their supply chain. This not 26

DOORS, WINDOWS & BALUSTRADES

only significantly reduces risk but also promotes stakeholder confidence. It also goes some way to meet the demand for improved product traceability. One system supplier now insists that all stages of the supply chain, up to and including doorset manufacture, are third-party certified to the BM Trada Q-Mark Fire Door Manufacturer certification scheme. Its door blank meets the requirements of the Q-Mark Door Blank scheme to STD 047 and the fire entrance door range is stocked and distributed under Q-Mark STD 171/050 for fire resistance and PAS24 enhanced security. It is available across the UK through a network of official doorset manufacturing partners, each selected, audited and tested to meet the nonmandatory requirements of Q-Mark STD 170/050, to demonstrate and prove competence in manufacturing the system with a robust factory production control process. By choosing to mandate the supply chain, this system supplier has more autonomy and control than its competitors. It can control all components apart from door closers and sealed units; however, these must match the tested specification.

The golden thread

Installation and maintenance are critical in the lifecycle of fire doorsets. While great strides have been taken with the supply chain, significant change will only

occur if we can encourage installers to be certified and maintenance teams are empowered through product knowledge and access to data. As custodians of a system that offers protection for both life and property in the event of a fire, our aim is to establish a future-proof technology that will close the loop on supply and maintenance, in utilising chips for key data storage, for example. 27

This would go some way to supporting the Building Safety Bill (published on 5th July 2021) requirement for a golden thread of information “…created, stored and updated throughout the building’s lifecycle. Establishing clear obligations on owners and enabling swift action to be taken by the regulator, wherever necessary”, (source: gov.uk).

Sound considerations

To avoid noise transference and reverberation problems, designers need to ‘design with their ears’ and make acoustic considerations a key issue right from the start of a project. They should factor in the need to prevent noise transference, and to absorb sounds, echoes and resonances within the spaces where they originate. This requires them to consider the likely acoustic impact that the size, height, volume and shape of their intended design will have. The presence of any hard, reflective surfaces used within the space, and even the intended furnishings, can all play a part in this process. Every building presents a unique challenge, and there is no standard strategy that is guaranteed to provide a perfect acoustic environment.

A StoSilent Distance acoustic ceiling system was used to create a balanced and practical acoustic environment for this listed landmark building in London

Fortunately, modern alternatives are available which allow the creation of monolithic, seamless surfaces that combine the ability to satisfy the modern trend for clean, uncluttered lines with outstanding acoustic performance. This underlines the fact that today’s modern acoustic ceiling and wall systems can provide excellent performance while taking the bold visions that architects and their clients have for their buildings and translating them into reality. Given the specialist nature of acoustic considerations, it’s not surprising that the subject is sometimes thought of as some sort of ‘secret’ known only to a chosen few. Yet, with careful consideration, and the help and guidance provided by specialist engineers and manufacturers, there is no reason why your next project shouldn’t sound every bit as pleasing as it looks.

1. Internal use

The best place to start is a good discussion with the client on their expectations and identifying the use of the space and potential future uses. Upgrading the internal environment at a later date can be an additional cost and a reduction in internal space.

2. Waterproofing specialist

The current industry guidance document BS 8102:2009 advises that a waterproofing specialist should be part of the design team, and that they should: be suitably experienced be capable of devising solutions that accommodate the various project constraints and needs provide the design team with information and guidance that assists with and influences the design, installation and future maintenance of the waterproofed structure.

3. Grade of watertightness

A clear and established grade should be identified, or in a mixed-use space, multiple grades can be discussed and agreed upon. As detailed in BS 8102:2009, there are three grades of protection available: Grade 1: Basic Utility – some seepage and damp areas are tolerable Grade 2: Better Utility – no water penetration but moisture vapour/some damp patches tolerable Grade 3: Habitable – totally dry environment Additional requirements (formerly Grade 4) – as Grade 3 but consideration of internal environment required.

DRAINAGE & LANDSCAPING

Tree maintenance requirement

MEETING NEW PLANNING REQUIREMENTS FOR TREES Extensive tree planting and retention of existing trees in developments, with provision for long-term maintenance, has just become a priority with new Government policies taking effect. Concrete block permeable paving offers an important opportunity to help satisfy these requirements with irrigation integrated with SuDS, hard surfaces and urban design – as the trade association Interpave explains. INTERPAVE

he latest requirements for trees in developments have been established in the July 2021 National Planning Policy Framework (NPPF) for England. The NPPF sets out what local planning authorities (LPAs) will require, when setting local policies and also considering planning applications for all developments. The NPPF states that: “Planning policies and decisions should ensure

FC&A – OCTOBER – 2021

However, measures need to be put in place to nurture and allow trees to mature, generally for decades, enabling them to actually deliver their real potential – including net-carbon storage, urban cooling through shading and evapotranspiration, biodiversity and public wellbeing. So, the NPPF also requires that “appropriate measures are in place to secure the long-term maintenance of newlyplanted trees, and that existing trees are retained wherever possible”. Urban trees and paving have traditionally been seen as in conflict. But this is not the case, with concrete block permeable paving (CBPP) a key sustainable drainage (SuDS) technique to reduce flood risk and make cities more liveable. CBPP offers unique opportunities to collect, attenuate and treat rainwater runoff, removing pollutants before irrigating green infrastructure. Unlike conventional impermeable hard landscape materials, CBPP allows the same pattern of runoff transfer to the ground as natural vegetation, allowing water to reach tree and shrub roots, despite providing an attractive hard surface above. Local planning authorities now need to incorporate long-term tree maintenance measures in their planning consents and a straightforward spatial solution, such as permeable paving providing irrigation, offers a holistic multifunctional solution.

Beneficial relationship

that new streets are treelined and that opportunities are taken to incorporate trees elsewhere in developments.” This is backed up by other recent Government and local guidance such as the National Model Design Code, which says: “All schemes will be expected to follow national policy by achieving a 10% net gain in biodiversity. All new streets should include street trees.”

A recent Interpave case study (available via www.paving. org.uk) explored the 20year beneficial relationship between CBPP and trees at the Martlesham Park and Ride scheme. Here, concrete block permeable paving has operated efficiently with minimal maintenance amongst extensive tree planting without root disruption or other issues. The benefits of CBPP for trees while retaining

accessibility are recognised by the current Code of Practice for accessibility in the external environment, BS 8300-1:2018, which states that: “Tree grilles should be avoided. Smooth or paved permeable surfaces should be used wherever practicable.” Permeable paving can be laid level and still avoids puddles without the need for drainage gulleys. It provides a safe, firm, pot-holefree surface for everyone – including wheelchair users and people pushing prams. Two decades of experience in the UK demonstrate the long-term performance of CBPP with minimal, if any, maintenance. CBPP generally comprises an upper layer of concrete blocks with permeable jointing and laying course, over a sub-base and other structural layers of permeable material for water storage. Interpave is currently exploring new ways of applying CBPP to optimise gradual supplies of water for tree irrigation at both levels, as well as effective interaction with tree planters and proprietary tree pit systems. Paving layouts are also being considered to maximise the permeable paving catchment area for tree irrigation, particularly outside the protective tree-canopy zone. Interpave would be pleased to hear from anyone considering integrating permeable paving and trees on projects (email: chris.hodson@ paving.org.uk).

Low intervention retrofit

Another important innovation, particularly for regeneration, is the retrofitting of CBPP as an overlay to existing, conventional road bases or other hard surfaces. These thin overlays create attractive, safe and sustainable shared surfaces. They can be particularly effective when used to supply a gradual flow of clean water horizontally into raingardens or bioretention areas with trees and other green infrastructure, via simple slot inlet/outlets, to store water for irrigation and biodiversity,

DRAINAGE & LANDSCAPING

as well as SuDS. Such lowintervention techniques enable transformation of the public realm in response to the raft of recent active travel, low traffic and open space initiatives. This approach is exemplified in Bridget Joyce Square, London, an important regeneration project designed by Robert Bray Associates (RBA) in conjunction with McCloy Consulting for the London Borough of Hammersmith and Fulham, which won the top prize at the 2017 Landscape Institute Awards. Here, a typical, adopted asphalt street and adjacent parking areas were transformed for community use with CBPP overlay shared surfaces and tree-planted raingarden basins – an exemplar for future urban landscapes. The basins provide water storage for SuDS to reduce overloading existing drains (in the absence of the CBPP sub-base), as well as for irrigation.

Well-established green infrastructure

Interpave revisited the project in August 2021, around five years after completion, and

they have thrived here and the vegetation has remained green all summer. The critical thing seems to be that even small rainfall events are captured by the permeable paving in summer and with larger events concentrated in the basins.”

Sapphire’s logistical expertise has assisted the smooth supply of over 40 of its Glide-On balconies to Eastlands E05, part of the extensive Wembley Park development surrounding London’s iconic Wembley Stadium. Given the central location and proximity of the stadium, there was very limited storage space on site and strict security procedures for deliveries. Sapphire worked closely with delivery drivers and site teams to ensure balconies arrived on site to precise pre-booked timeslots. To facilitate delivery, Sapphire also redesigned its double-stacking trailer to allow twice as many balconies to be transported per load. The use of MMC at Eastlands E05 enabled the challenges of the site location to be overcome without compromising quality or

he UK market has a fairly unique perspective on product guarantees, requiring guarantee periods of 25, 30 or 40 years, usually as a complete building envelope system. This should normally require a provider to specify all the components that make up a system, to test them, verify their performance, supply as a complete package, and police the installation to ensure compliance. Guarantees should be meaningful and offer genuine benefits to the client. Checking the small print in any system guarantee

and understanding the true intent behind the paperwork is always an important aspect when selecting a manufacturer to specify. Who is ultimately responsible? Is there a single point of liability? Are the components ‘off the shelf’ for convenience, or supplied to the system provider’s exacting specifications? If the guarantee is backto-back with a component supplier, does this mean that upstream supplier’s terms and conditions take precedence? Are any products that make up the system excluded?

In 2007, Eurostar decided to move its operations from London Waterloo to St. Pancras, taking advantage of the historic surroundings and the UK’s first highspeed line, the HS1. We were appointed as architects on behalf of Eurostar to strategically design sections of the iconic station as part of an £800m restoration. This required careful conservation efforts to redefine the station for the 21st century, marrying iconic Victorian architecture with state-of-the-art facilities to create the now iconic and muchbeloved station. Detailed visual mock-ups of the walkways and flythroughs were created to demonstrate spatial awareness, and in an 18-month project, we worked as Eurostar’s final delivery contractors to design, manufacture and install the station fit-out. The result was a building that remained true to its heritage while also being fit for purpose in the modern world, so we were very proud to be awarded the RIBA English Heritage Award for the project. Remaining faithful to the history of a building is key with conservation. When upgrading facilities at the station, we knew we had to keep any additions sympathetic with the historic red sandstone and cream Chris Monk, Managing Director at The Input Group, believes the conservationashlar trim building. of historical buildings is the cornerstone of a varied and unique landscape.

he new JC6-KB range of A4, grade 316 fasteners has been introduced by the Yorkshire-based team in tandem with EJOT’s global upgrade to its established JC2 concrete screw range, which now offers significantly greater application potential. It has the assurance of a European Technical Assessment (ETA) approval for Option 1 concrete applications for use in both cracked and noncracked applications. These range from facade scaffolds, temporary fastenings and contact surfaces to cable racks, handrails, battens and formworks thanks to availability in lengths between 67 and 150mm. The R&D team’s goal was to broaden the scope for using concrete screws in more demanding situations, particularly those with environmental classifications C1 to C4, in accordance with BS EN 12944, and give construction professionals further fastening options. The result is a bi-metallic, hexagon-head concrete screw that is easy to distinguish through its gold marking. The fastener is available in 6, 8, 10 and 12mm variants formed using corrosion-resistant A4 grade austenitic stainless steel for the main fastener body and head, which is uniquely welded to hardened carbon steel on the lead threads. This JC6-KB’s design also includes ‘anti-backout’ serrations. These serrations form part of the under-head design to provide a much greater grip into metal fixture materials such as aluminium. It is part of the innovation that ensures the screws are EJOT’s UK-based R&D team has played an instrumental role in as easy to use as all the products in the EJOT JC2 the global fastener manufacturer’s diversification strategy withconcrete screw range. the development of a new range of high-performing concrete It provides a more versatile fastener compared screws for use in more demanding applications. to anchors, given its relatively simple installation EJOT technique and the fact that it can be adjusted. And as the concrete screw requires no expansion, it can be used closer to the edge of the concrete versus anchors. Being A4, grade 316 stainless steel, it is approved for environmental classifications, including “severe industry characterised by fall out and emissions of stacks, sulphur and acid smells”. This encompasses plant buildings immediately under stacks as well as buildings with high internal humidity and/or corrosion from operations within. Richard Bowhay, Sales Manager for Building Fasteners at EJOT UK, said: “Our expanded range of concrete screws is an important step in EJOT’s continued diversification which is providing precision-engineered fasteners to an ever-broader customer base right across the construction industry. Whilst concrete screws are long established in the market, our R&D teams are always working to enhance all the fastening solutions we manufacture to ensure construction quality, efficiency and safety can be continuously optimised – this is what underpins our latest innovations.” The A4 grade 316 JC6-KB is one part of EJOT’s recently-upgraded range of concrete screws. This includes the JC2 range, which offers five further screw types suitable in Option 1 cracked, noncracked and hollowcore concrete suitable for a wide variety of construction applications, all designed and manufactured to EJOT’s high quality standards and ETA-approved.

First debris screen for Combar

Torkington Park debris screen under construction

Combar has been used for the first time in the construction of the debris screen structure at Torkington Park, in Hazel Grove, a suburb of Stockport. The brook that flows through the park is culverted under a road from the downstream end. Heavy rain in the past had caused the debris screen located at the culvert inlet to become blocked, causing a local flood event. As a result, the Environment Agency (EA) took the decision to rebuild and upgrade the downstream debris screen to reduce the risk of future flooding. CHC holds a place on the Environment Agency’s Flood and Coastal Risk Management Operational Framework (FCRM), created to deliver design, civil engineering, culvert clearance and maintenance works in the river, coastal and estuary environments. The company was also successful in its application for funding from the Environment Agency Net Zero Carbon Innovation Pathway Fund (2021/22) – and it is this that led to the collaboration with Schöck.

Ticking the boxes

CHC Site Manager, Lee Farrar, takes up the story. “Using the Schöck Combar product ticked quite a few boxes,” he explains. “Being a GFRP reinforcement, it offers a reduction of up to 80% of embodied carbon when compared to traditional steel reinforcement. Other benefits are that it is significantly lighter than steel, so the health and safety benefits involving manual handling are significant. The GFRP reinforcement doesn’t rust either. So the finished structures are more durable and require less maintenance while still achieving an expected design life of 100 years. The Torkington Park debris screen reduces the risk of flooding to the surrounding houses, and its design results in fewer visits being necessary by the EA to clean out the screen debris. We are looking to incorporate Combar more widely in future designs and anticipate using the product again very soon.”

BUILDING ELEMENTS

The key benefit for worktop use is that TopOil is extremely water repellent, helping to make surfaces more durable. It is resistant to common liquid spillages such as water, juice, tea and wine, making it ideal for the kitchen. It has a microporous, breathable finish that does not crack, peel or flake. Using the product regularly can prolong the life of your worktop, so you won’t need to replace it.

Treating your worktop

To get the best performance from TopOil, you need to get an optimal volume of this hard wax oil into the fibres of the wood. To help with performance on worktops, the wood will normally require the surface to be sanded to a maximum of a P150 grit grade (depending on the wood species). To deliver the ideal amount of the finish into the absorbent wood surface, it’s recommended to apply the first coat thinly along the wood grain with an Osmo microfibre roller, flat brush or oil finish applicator fleece. Allow to dry for approximately eight to 10 hours and ventilate the room well while drying. Then, apply the second coat with an Osmo oil finish applicator fleece or a Wooden worktops look stunning in almost all kitchen styles and colours, lint-free cloth. It is possible to spot sand and repair surfaces, worktops take the brunt of the wear and tear in a busy home, so they any watermarks. It’s necessary to use the same finish sanding grade to sand OSMO back, then retreat those spot areas using the same application technique originally carried out. Once these areas ver time, water damage and worktops at their best, treat with Osmo have been allowed to dry, apply a little mould can affect wooden TopOil. Newly-oiled wooden surfaces more oil to build up some protection. worktops, especially around using TopOil require approximately two areas like the sink, so prevention is to three weeks to completely cure and Use an Osmo applicator fleece/pad for better than cure. To keep wooden harden properly before normal usage. this procedure. Finally, care must be taken with the cleaning and maintenance of the TopOil. For regular cleaning (perhaps daily or weekly), this should ideally be carried out with products like Osmo Wash and Care or Osmo Spray Cleaner. These products clean the surface without breaking down the natural oils and wax in Osmo finishes. The soaps within these products contain a tiny amount of natural oil to help nourish the surface over time. Products, such as washing up liquid, are designed to strip away oils and waxes, therefore, the finish will require topping up if there is high exposure. You could top up thinly with a cloth to the clean, dry surface using Osmo TopOil or Osmo Maintenance Oil products. Osmo Maintenance Oil is very practical as it is much thinner than TopOil, and there is less risk of building up too much wax on surrounding treated areas. With the right care, Osmo TopOil can enhance the natural beauty of your wooden worktop and keep it looking new for many years to come.
