Sustainable HVAC Approach

DC-Arc-Proof Your Power Allbro proudly unveils its groundbreaking innovation: the ALL-DB range of Domestic Distribution Boards. These boards, essential components in the intricate web of household power distribution, are set to redefine the way we approach renewable and backup power installations in existing homes. With a fusion of cutting-edge technology, safety considerations, and design elegance, ALL-DB charts a new course for efficient and secure power management. The surge in renewable energy installations and backup power systems necessitates a paradigm shift in installation techniques. Retrofitting distribution boards requires innovative solutions to cater to these evolving demands. Enter the ALL-DB, a meticulously crafted response to the shift in residential power distribution. Designed and manufactured in South Africa, for the world.

Glass Reinforced Polyester Retrofit distribution boards don’t benefit from the insulation and protection offered by surrounding brick and mortar. Utilising plastic materials in distribution boards introduces a heightened risk of fire hazards. ALL-DB’s transformative edge lies in its adoption of Glass Reinforced Polyester (GRP), a robust thermoset material celebrated for its superior insulation and flame-resistant properties. This choice of material eliminates the need to compromise between safety and practicality, ensuring installations are both secure and durable. GRP is widely favoured by leading commercial solar farms, where it is used for combiner boxes due to its proven reliability.

Mounting Bracket System The ALL-DB’s unique installation method utilises a mounting bracket, which is first mounted to the wall. The distribution board is then fitted to the mounting bracket through pre-moulded holes in the base of the enclosure. This system makes installation easier and more accurate.

Cable Entry System Cable access, a pivotal consideration in any electrical installation, has also been revolutionized by Allbro’s design prowess. The new ALL-DB range features an elegant cable entry system at the backplane, eliminating the struggle associated with looping cables at varying distances from the wall. This innovation ensures tidy installations, enhancing the visual appeal of home power setups.

EDITOR’S NOTE Gareth Griffiths | editor@tobuild.co.za Back in 2014, the City of Cape Town was awarded the official status of “Design Capital of the World”. In compiling this edition of TO BUILD, we realised that many of the design-rich projects covered by the magazine in recent times have, in fact, been in Cape Town, but also nationwide. Since 2014 and despite a recession and South Africa’s other woes, a remarkable and innovative change has happened within design in the built environment, across all disciplines and also all our major cities. It seems that South Africa, in the spirit of the Design Capital 2014 experience, has been inspired to bring out the best in terms of creating a built environment fit for purpose and fit for the future In terms of the Mother City, one thinks of bespoke projects such as the V&A Waterfront Silo MOCAA, the Ridge, the D-School, and the Curro Durbanville campus - many of which have been bestowed with global awards. The City was lauded internationally for its innovative handling of the crippling drought in 2018, and more recently, by keeping the electricity supply going by two levels, despite the severity of loadshedding countrywide. It is inspiring to see leading engineering firms, contractors and suppliers of products and systems to the built industry, rising to the challenges of global warming, sustainability and urbanisation. So, has the World Design Capital investment by the City paid off over time with benefits to the whole of South Africa? You be the judge.

Flexible workspaces

grow 44% post-pandemic With reports coming through of the demise of the era of working from home, born off the back of the pandemic and lockdowns, it is interesting to track the performance of rented and shared co-working space offerings as a flexible working solution somewhere between the home office and the formal office. Workshop17 Around the world there are currently over 35 000 coworking spaces1 with that number expected to rise to 41 000 by the end of 2024. This is a growth rate of around 21%. In South Africa that percentage has more than doubled to 44% growth, indicating that serviced and flexible workspaces offering new ways of hybrid and remote working are here to stay and have been quickly adopted into our lifestyles, says Paul Keursten, CEO of Workshop17, (www.workshop17.co.za) a South African founded co-working space and meeting room operator company with its own unique operating model. Where the serviced office was traditionally for freelancers and smaller companies, larger companies are now seeing the advantages of bespoke workspaces that are attuned to their own brand and culture, while at the same time being fully serviced and part of a network of spaces and a wider community. This year alone, the company says it has recorded unprecedented growth and has expanded five of their South African locations and opened a second and third location in Mauritius. In real terms they added 5 700m2 of serviced workspace in South Africa, and 2 500m2 in Mauritius. This brings their total offering to 30 000m2, in 10 locations. Their plan is to double their footprint in the next three years, starting with two new locations, which will open in the first half of 2024. In an industry where only one in three service providers usually report profitability, Workshop17’s occupancy rate is 90%, with over 5 000 members and 745 different References (1) www.flexas.com/blog/coworking-statistics

companies, providing unique networking opportunities within the business ecosystem.

a broader client base a bigger choice of locations.

Keursten attributes their upwards trajectory to being proactive to client requirements: “Our members are essentially an integral part of our growth plan giving feedback on product services and ideas. We’re creating locations fundamentally designed by our members' needs and wants and building larger and newer Workshop17 communities in hubs where the demand is high, offering

“In 2012, the idea that (co-founder) Mark Seftel and I had for a new kind of desirable workplace built on the principles of service and hospitality may have seemed idealistic. However, since Covid, it has become one for everyone,” Keursten adds. The success of this formula seems to be heralded by its profitability with continued high occupancy, and a contract renewal rate of 85%.

symbiotic relationship Whether you're an interior design enthusiast, a seeker of personal growth, or simply someone looking for inspiration in today’s chaotic world, the second edition of My Yellow Room by Kim Williams promises to be a source of enlightenment and joy, says the publisher. Kim Williams My Yellow Room was originally conceptualised during the challenging days of the first Covid lockdown in 2020, to highlight the importance of our physical spaces and their impact on our mental wellbeing. Now, in its second edition, Williams wanted to make the book more applicable to current times, and inspirational in terms of life and philosophy.

“I especially wanted to unpack how the behaviours we have acquired over time can have a profound effect on our interiors," she says. “My desire is for My Yellow Room to resonate with everyone as there's an important message in here about the symbiotic relationship between our life

The project is expected to break ground towards the end of 2023, five months after launching, where the development bucked market trends by garnering a mammoth R100 million in sales within just 30 days of its launch. A feat which many will regard as a positive indication of the vibrancy of the Hillcrest market. “We are energised by the overwhelmingly positive response the market has shown toward this development and its offerings. This further reinforces our belief that choosing property is always a smart investment decision,” Geoff Perkins, MD of Collins Residential says. “As a team we are committed to consistently delivering our best and surpassing expectations. Emberton Estate as a whole transcends bricks and mortar, it has become a beacon of lifestyle and active living in Hillcrest. With over 400 families now calling it home, the development has seamlessly integrated itself into the Hillcrest community.” Aviva Emberton Estate stands as a gateway within the existing estate, offering premium studio, 1, and 2-bedroom apartments. Characterised by open-plan layouts, abundant natural light, and top-of-theline fixtures, these walk-up, three-story apartment buildings create a warm and vibrant atmosphere. It offers a hassle-free lock-up-and-go living experience, complete with an included parking bay and the option to acquire an additional one, say the developers.

FOURWAYS GROUP

Fourways Group: Leading the way in eco-friendly HVAC solutions Fourways Group, an accredited supplier of leading air-conditioning and heat pump brands, has earned a reputation as a trusted specialist in providing multifaceted air-conditioning and water temperaturecontrol solutions. Their commitment to excellence aligns seamlessly with the ecoconscious vision of Thaba Eco Lifestyle. Fourways Group's pivotal role in the Thaba Eco Lifestyle project extends beyond its expertise in HVAC solutions and being the exclusive distributor of Samsung Digital Air Solutions products in South Africa. Notably, Fourways ensured that the product specification aligned with IMECH Consulting Engineers mechanical requirements and Baldwin’s vision for an eco-friendly and sustainable environment that consists of energy-efficient HVAC systems. This strategic partnership between Fourways Group and Samsung Electronics signifies a commitment to cutting-edge technology and sustainability in the space of air conditioning solutions. At the heart of their contribution to the Thaba Eco Lifestyle project are the innovative Samsung 360 Cassette ceiling air conditioners. With a sleek matte black finish, these inverter (energy-saving) models are the epitome of style and performance. The strategic installation of 360 cassettes on both the lower and upper ground floors, as well as ducted hideaway splits in the Courier Guy area on the lower ground floor, ensures that employees and residents enjoy unparalleled comfort and energy efficiency. But why did Thaba Eco Lifestyle opt for Fourways Group's expertise and the innovative Samsung 360 Cassettes? Let's delve into their strategic selection.

A choice guided by excellence In the pursuit of reducing energy expenses, minimising installation downtime and service costs, and establishing a standardised, flexible, and safe system, the demand for innovative climate solutions has grown significantly. Developers are seeking eco-friendly, user-friendly, and cost-effective climate systems. 16

summer 2023 | www.tobuild.co.za

One might wonder about the selection of Fourways Group and Samsung 360 Cassettes for this project. Unlike projects where suppliers are dictated, Thaba Eco Lifestyle's decision was influenced by a combination of factors. Fourways was chosen due to their topclass, energy-efficient products, strong sales support, and exceptional technical assistance. As for Samsung 360 Cassettes, the project's CE opted for them, recognising their innovative technology and efficiency. Their choice was also guided by their ability to seamlessly complement the architectural and interior design, enhancing the project's overall appeal.

Air Azul's expertise A project of this magnitude demands the expertise of an outstanding HVAC installer like Air Azul. Renowned as one of the top contractors in the country, they embarked on this project fully prepared to deliver a superior installation that would endure the test of time. “ Air Azul installed a range of capacities of the 360 Cassette, spanning from 4.7Kw to 7Kw. Moreover, they outfitted various spaces, including the laundromat reception, server rooms, and numerous residential homes, with ducted and mid-wall inverter units, boasting cooling capacities ranging from 5kw to 17kw, perfectly meeting the diverse requirements of each.

360-degree cooling- all round comfort The name "360 Cassette" comes from this indoor aircon’s ability to deliver airflow in all directions. Conventional 4-way cassette type air conditioners create an uneven air flow, with areas that the cool air can't reach, as they only blow cold air in 4 directions*. Therefore, depending on where you are, you’ll notice that there are different temperatures across the room. The 360 Cassette features a circular outlet that blows cool air in all directions, so that every corner of the room has the same temperature. The 360 Cassette has a bladeless design, so cool air disperses gently and descends across the room like a natural wind, making people feel comfortably cool without the sensation of a cold draft on their skin**. As there are no blades to block the air flow, especially at low angles, it expels 25% more air* and spreads it farther, which means you can quickly enjoy a more comfortable environment across a wider area. The 360 Cassette's circular design seamlessly complements various interior styles, enhancing the aesthetics of any space. Its elegant minimalist look adds sophistication and uniqueness, particularly when installed in exposed ceilings – a hallmark of contemporary architecture.

A holistic eco experience The way heating and cooling systems were designed, implemented, and utilised to minimise environmental impact allows residents to breathe easy in the embrace of a fresh and clean indoor climate, all thanks to the 360 Cassettes powered by Samsung DVM S VRF outdoor systems. In this harmonious blend of technology and nature, Air Azul, IMECH, and Fourways Group played a pivotal role in turning this vision into a tangible reality.

It was a dream project because of the idyllic site and brief. The client wanted the very best outcome. A beautiful building was the aim. They worked very closely with the design team through each stage of design development and during construction - LA.

summer 2023 | www.tobuild.co.za

HOTEL HAZENDAL

It is hard to say exactly what aspect of the new Hazendal Hotel & Spa grabs the visitor first. Its green areas, the golf course, or its interiors. The hotel at first appearance is low profile, almost discreet, to the eye. It blends in with a sensitive environment - exactly as designed to do. A low profile and sensitive development is clearly what the designers had in mind, given the fact that the approximately 3 000m2 set of buildings would have to marry with the Cape Dutch architectural legacy of the existing estate, which finds its origins back to 1699. Interestingly, the “haas” in the name of the estate is ironic in that its founder, Christoffel Hazenwinkel, originally settling from Germany, implies naming of the estate dating back 400 years. However, the name was in fact given due to the abundance of real Cape Hares in the area. Hazenwinkel, therefore, named his property Hazendal, the ‘Valley of the Hares’ way back when; a name which endured since then.

MAIN PROJECT

The new hotel Director of Hazendal Wine Estate, Simone Voloshin, explains that in the eight years since the Voloshin family started their extensive renovation and development of Hazendal Wine Estate, it had become apparent that a luxury hotel, located on the grounds of the estate, was needed to complete the property experience. Lee-Ann Adendorff, the Project Lead at Boogertman Architects, spoke to TO BUILD about the incorporation of these principles in the entire conceptualisation of the stunning new hospitality feature. She says that landscape and outdoor spaces are a key part of the design. "The landscape areas were specified to match the existing estate; indigenous plants and paving to match. The pool and water feature with mosaic art were to be a feature. The courtyard was designed to accommodate a large marquis tent for outdoor events. The bar and ballroom overlooks the golf course and Bottelary Valley, and the bedrooms have private decks facing a water reservoir,” she explains.

Under its current owners since 1994, a family foundation, much has been done to ensure the legacy of the Cape Hares in the field by ensuring sound sustainable and green practices were made central to all its development.

MAIN PROJECT HOTEL HAZENDAL

The interior Interior design architect, Maurette van Eyssen of Midesign Interior Design Studio, says that their design brief was clear: to create a modern hotel that places the highest priority on comfort while embracing the values of family life. “This project evolved as a hybrid, striking a balance between traditional glamour and contemporary implementation, resulting in a family-friendly experience. Hazendal immediately stands out with its lush gardens integrated into the environment. The result is an exclusive family retreat, offering 31 Superior and Luxury Rooms, 24 of which are interleading. There are also two lavish Junior Suites and a Presidential Suite.” The overall interior design features a soft, bright, and colorful palette, “inspired by 22

nature and complemented with locally sourced natural materials,” says van Eyssen.

and ladies' locker rooms, inspired by the beauty of the Cape Winelands.

The rooms and interiors offer a timeless ambiance with modern conveniences seamlessly woven into the design. Crowning glory, the presidential suite, features a fully equipped butler's kitchen and boasts a classic and timeless design.

Van Eyssen says that the interior design of each suite was meticulously curated by the team to provide the comforts of home within an intimate setting, complete with expansive terraces and beautiful outdoor living spaces.

Water plays a starring role throughout the hotel, and indoor gardens within the passages offer a calming, green-friendly atmosphere. In addition, the clubhouse provides a fully equipped gym with men's

“The spa aims to maintain a strong connection to the natural surroundings. The result was a spa inspired by biophilic principles, embracing a human-centric wellness design approach intended to reduce stress and enhance creativity and overall well being,” she adds.

HOTEL HAZENDAL

Preserving the legacy Interestingly, the spa is located in the original barn which was partially preserved during the restoration of that part of the existing property. Adendorff takes up the story: “We had this early 18th Century building which was quite dilapidated, but at the same time could not be demolished or changed too much. This was to become the spa. “We retained the walls, roof and window and door openings but had to have replica doors and windows to match. Hence, the windows were wooden sash windows. “At the kraal portion at the back of the existing building, there were two walls which were crumbling. To preserve the stone the contractor had to store the original stones and replace them by hand-fixing back-to-back walls with hoop irons. The stone walls would not support their own weight without the concealed brick wall to reinforce them.“ Hence, expertly-developed methods by Afrimat (CLC), covering the use of lime for heritage and old-buildings restoration and crack repair work in South Africa, was utilised.

MAIN PROJECT

Alongside the existing building was a new steel framed extension to the spa. This contrasts with the legacy building in being very new and modern. The black steel frame and structural glazing flank the existing stone and lime washed walls. Van Eyssen adds that the interior design was carefully modelled to embody a "work, live, family, and play" ambiance. Rounded curves, playful colours and touches of green and gold abound. The use of various forms and shapes in the decor ignites curiosity and encourages guests to explore every corner of the space. Art installations are integral to the project, enhancing the overall experience. 3D designs and virtual walkthroughs allowed for numerous iterations and client input, ensuring that the project met the highest standards without compromise. The exterior design, characterized by its curves, harmonizes with the interior, with captivating mosaic and wall installations”.

Cigar, anyone? The library, family lounge and cigar bar blend various key material choices seamlessly. The beautiful chandeliers in the main bar area and other double-volume spaces, with a modern take on classic mid-century design, feature golds and textured fabrics.

Symmetry - the old with the new. The reflection at the bottom right of reception window mirrors the angle of the old. A conscious element of the design.

The outdoor spaces Mariska Els, Landscape Team Leader, Boogertman & Partners in Pretoria, says that the Hazendal hotel landscape encapsulates the beauty of the entire site with its opulence and intricacy of design elements. Each space is distinctly designed for its purpose to ensure the guest enjoys their visit in this eclectic collaboration of old and new. “As Hazendal is a precious heritage site, the landscape provides experiential spaces created in the unique outdoor rooms set to

The Tin Shack The Container St Helena house, aka The Tin Shack (www.pocheconcepts.com/thetinshack), was built near the beach at St Helena Bay using two 12m containers. Conceived as an Airbnb unit, it consists of two shipping containers split into two-bedroom wings, with ensuites and custom built-in cupboards. Ayla Damon

ARCHITECTURE

Despite the narrowness of the container structure, the two-bedroom spaces do not feel cramped. The large open-plan living area has an ample-sized kitchen with a dining and lounge area to allow the occupants to enjoy the fireplace in winter and the coastal views in summer. The large sliding doors lead onto the sheltered decked area with a KolKol hot tub which balances on the edge of the deck. The property is located on an elevated section of St Helena Bay, so it was important that the views were unobstructed, and that the unit was located in a private enough space on the property to allow the guest to enjoy the local vegetation, wildlife, and birdlife. The tranquil and calming interiors consist of a combination of white and grey tones to not detract from the outside landscape. The container theme was carried through to the interiors as the bathrooms are kitted out with industrial brass fixtures and sanitaryware, a vertically clad metal wall was added in the shower and as a splashback to the basin. The architect’s design had to take cognisance of bushfires so the area around the container footprint was cleared and built up with terraforce retaining blocks to create a house platform. This was then filled with a pebbled path and apron to create a surround. The containers were built using non-combustible materials with a suitable fire rating. The design is very simple and straightforward as the build was done by the owners, who executed it superbly. www.tobuild.co.za | summer 2023

PROJECT

Sustainability factors An important factor, sustainable principles, and materials were incorporated as follows: • The quick building time meant fewer resources such as water were required for construction. • Double glazing was installed to prevent too much heat gain and glare. • Energy-efficient light bulbs were used. • Permeable paving with waterwise landscaping was used. • Greywater and rainwater collection was installed. • Recycling building materials as well as the containers themselves were given a new life. • Portions of the container sidewalls that were cut out to join the two containers were reused as walls on either end of the patio. • Minimal materials were used meaning a low carbon footprint. • A monopitch roof was installed to collect as much rainwater as possible to be reused. • The gas geyser, stove, and fireplace installed make the structure less reliant on electrical supply. • Composting toilets were installed. • A solar panel system is envisaged for the near future.

ARCHITECTURE

Structure and finishes The containers are supported by concrete pad footings with a concrete plinth wall, this was filled in loosely with rocks found on the property. The container points are fixed to the concrete plinth wall with base plates all designed by the engineering team. The architects were fortunate that in this area the containers could remain exposed. They were painted in a grey tone finish that the clients chose, which helps blend the containers in with their surroundings. Because the containers were left in their natural state, it avoided transporting any unnecessary cladding materials, and a minimal amount of timber was used, creating less of a carbon footprint for the build. The deck was semi-enclosed using offcuts from the container walls, which makes building with recycled containers even more eco-friendly. The roof structure was built on top of the container rooftop, which not only serves to collect rainwater, but shades glazed areas and protects the containers from the elements. uPVC double glazed windows are used throughout. The interior of the containers was framed with light steel and then clad with Rhinoboard from Gyproc. A foil-faced insulation barrier (Sisalation) was also added to the walls and roofing along with rock wool insulation. The ceilings are Isoboard, which also serves as insulation.

Perfectly encapsulating the importance of liveable design, Ayla says that Poche refers to the solid spaces found between the walls of homes and businesses. “As designers, we know it is not enough to focus on the massing of a building; the spaces in-between hold the key to design, and comfort, that will last”, she says.

DESIGN INTERIORS

A symphony of

simplicity& experience Apart from being a topic close to every restaurant diner’s heart with a direct line to the stomach, restaurant design is not merely about creating a space to eat but about crafting a sensory journey. If you want a functional view on the topic in addition to form, ask a former well-known chef. So we asked the founder of KT Interior, Kobus Truter (www.kt-interior.com), successful chef turned interior architect, to share his thoughts on the topic. Kobus Truter Kobus Truter The sentiment rings true, especially today, where every corner, nook, and restaurant fixture narrates a story deeply entrenched in the brand's ethos and, more significantly, its DNA. My journey into the world of design began amidst the hustle and bustle of kitchens and the echoing laughter of dining rooms. As a chef and restaurateur, the allure of spaces and their capacity to transform human experiences was palpable. The ingredients of a dish, like the elements of design, need to be meticulously chosen and assembled to create something truly memorable. Travelling the world has been akin to reading an elaborate, vast book of design. The straight lines of Japanese architecture, the balance in a European piazza, and the simplicity of the Scandinavian interior have profoundly impacted my philosophy towards design. 32

INTERIORS DESIGN

Restaurants are venues of stories, emotions, and connections As I envision it, the future of restaurant design is a harmonious blend of simplicity and depth. Modern diners seek authenticity; they yearn for spaces that feel genuine, yet awe-inspiring. It's not just about 'eating out' anymore; it's about 'experiencing out.' Restaurants are no longer merely spaces; they are venues of stories, emotions, and connections. Every fixture, every wall, and every piece of furniture is a chapter in a restaurant's story. At KT Interior, founded in 2014, our holistic approach resonates with this ideology. We believe in the interconnectedness of parts, understanding that the success of a space lies in viewing it as a whole. This perspective has allowed us to focus intently on human senses, ensuring an immersive experience that speaks to the heart and the soul.

Magic lies in crafting elegantly simple yet profoundly impactful spaces With the future poised at the cusp of technological and design revolutions, the next chapter in restaurant design is set to be thrilling. Drawing inspiration from nature, colour, textures, and, most importantly, human behaviour, we aim to craft spaces that are not just functional but emotionally evocative. To sum it up, the ethos that guides my vision for the future of restaurant design is encapsulated in a simple phrase: "Simplicity... instead of overcomplication”. " As diners globally become more discerning and experiences-focused, the magic lies in crafting elegantly simple yet profoundly impactful spaces. As we venture into this promising future, I remain excited and optimistic. With the collaborative efforts of architects, designers, contractors, and artisans, we're set to redefine the dining landscape one design at a time. Here's to the future – simple, elegant, and utterly memorable!

Spending time in and around aquatic environments has consistently been shown to lead to significantly higher benefits, in inducing positive mood and reducing negative mood and stress.

A selection of aquatic hues is used to alleviate stress and invigorate our spaces. This colour combination looks to the restorative properties of water in times when concerns for our health and that of our planet take precedence, bringing a sense of calm and optimism for a lighter and brighter future. Building from momentum gained In 2022, specialist advisors advise a colour combination featuring three colours instead of a single one. This season, the company’s colour advisors propose a bespoke new blue colour combination based on a 60-30-10 ratio. This is based on an industry-standard design approach of 60% of a room being in a dominant colour, 30% in a secondary colour and 10% in an accent colour – making it easier for users to achieve a well-considered look. Hence a new trio of colours will emerge in 2024, following months of extensive research as the world recovers from the pandemic years and faces extreme climate challenges. Together, this layered and immersive harmony of hues awakens the restorative properties of blue, a colour that holds a pronounced ability to elevate mood and improve feelings of rejuvenation – even more so than green. While many of us have been seeking refuge in green spaces, like forests and parks, and incorporating leafy hues into our home, recent studies have found that blue spaces are associated with more positive measures of physical and mental wellbeing.

The science behind the blues Environmental psychologist, Dr Matthew White, a member of the BlueHealth programme researching the benefits of urban blue spaces, notes that, “spending time in and around aquatic environments has consistently been shown to lead to significantly higher benefits, in inducing positive mood and reducing negative mood and stress”. In light of these findings, and Plascon’s collective desire for calm, reassuring spaces, the design team looked to the allure of water to transform the home – and they didn’t need to look far: South Africa has a profound affinity with this life-giving source, thanks to our thousands of kilometres of coastline, many pristine lakes and abundance of waterfalls. www.tobuild.co.za | summer 2023

Unveiling the colours According to the suppliers, crystalclear Caribbean Sea (G7-A1-2) a colour representing the largest percentage in the design ratio, used on its own, evokes sun-lit shallow waters on a warm day, while its pairing with the other two – North Beach (B4-B1-1) at 30% and Aqua Pura (G7-C22) at 10% – captures the full spectrum of aquatic blues. The vibrant warm turquoise of the crystalclear Caribbean Sea (G7-A1-2) with its green undertone is invigorating, bringing energy and a sense of renewal into any space. North Beach (B4-B1-1) is a bold and saturated azure representing the enveloping comfort of the deep without being too cool. And the gently shaded blue-green Aqua Pura (G7-C2-2) is the perfect highlight, a pale near-neutral reminiscent of rays of sun sparkling on water. The Head of Decorative Marketing at Kansai Plascon, Suvasin Moodley, sees great decorative potential in this trio of colours. “Because Caribbean Sea, North Beach and Aqua Pura have been carefully selected by our team to complement each other, you can really play around with how much or little of each you’d like to add to your space,” he says. And, indeed, there are loads of ways to incorporate these stunning colours into your spaces. Aqua Pura (G7-C2-2) is an excellent choice for a more neutral base: add an accent wall to your lounge, use it to colour your kitchen cabinets or give your bathroom floor a makeover. The deep North Beach (B4-B1-1) can serve as an alternative to black or dark wood, working beautifully to transform wooden furniture or adding depth to your bedroom

“We wanted to make transforming your home into a blue space as simple as possible,” notes Moodley. “The colour combination for 2024 captures the vast spectrum of blue in nature, so by simply incorporating the trio into your home, you unlock its powers.”

SUMMER COLOURS KITCHENS

Adding colour to your

kitchen with flair With a kitchen renovation we are spoilt for choice when it comes to various finishes, textures, colours, patterns and materials to choose from. In all honesty, it can be quite daunting, not knowing if we’re making the right decisions. Should we play it safe? Should we be bold? What are the trends? Stephanie Forbes, Kitchen Specialists Association KSA Members Your kitchen may be the one room in your home that is the most neutral. White or wood cabinets and simple countertops make a kitchen look clean and uncluttered. An elegant and simple kitchen can also use a ‘pop’ of colour but how do you do this without dating or overwhelming the space? There is a very simple way to come up with a balanced colour palette for your space. It's the 60-30-10 rule!

How to use the 60-30-10 rule The 60% is the overall colour of the room, the background colour. When you look at the space you'll say, it's the gray room, or a white room, or a blue room. This is your predominant base colour. The next number in this rule is 30%. It will become the secondary colour in your space and will support the main colour, but be different enough to give the room interest. Think of it this way, you'll be using half as much of this colour as you did for your main colour. This could be showcased in your work surfaces, making them a contrasting colour to your cabinets, or on your island by making its cabinets a different colour to the rest of your kitchen cabinets. The fun percentage is the 10%, your accent colour. It can be bold or more subtle depending on what look you want. The 10% can be what gives the room character or keeps it much more neutral; it's really up to you. This accent can be brought in by means of soft furnishings, timber accents in seating, light fittings, small counter appliances or an accent colour on the cabinets or drawer fronts. 40

KITCHENS SUMMER COLOURS

Choosing the colours

Do’s and don’ts to help guide you in your choices

To choose the three colors for your particular space, a colour scheme based on the colour wheel is the simplest method. We recommend any one of these four options, bearing in mind the amount of natural light you have in your particular space:

DO’s: • Recognize that even if you have the most stunning cabinetry and counters in your kitchen, it can still benefit from well-placed and well selected colour. Even the slightest tint in a wall colour can transform a boring space without changing the overall vibe of the room. • Consider adding colour with lighting fixtures. The on-trend light fixtures feature metallics such as brushed gold, bronze, and black. • Learn the basics of cool versus warm colours. Being able to recognize the colour temperature of any colour you're considering will help you choose the right colour to coordinate with your counters and cabinetry. • Have fun with colour. Use the guides above to add a pop of colour with accessories and dinnerware.

Monochromatic

Choose only ONE colour and use lighter and darker variations of that colour in your space. This works best with a neutral colour such as gray, cream, white, or ‘greige’.

Complementary

Select TWO colours opposite from each other on the colour wheel. One will always end up being a "warm" colour and the other will be a "cool" colour, giving you a nice balance. The traditional colour wheel will give you the complimentary colours of red/green, orange/blue, yellow/purple

Analogous

Select THREE colours next to each other on the colour wheel, with the middle colour being the more dominant colour. An example of this would be blue-green, green, and green-yellow (green is the key through all three).

Split complementary

This is similar to complementary (listed above) but you add in a third colour to the combination. Select a main colour, find its complementary colour across from it on the colour wheel, and add one of the colours next to the complementary colour. An example might be, blue as your dominant colour, then orange as your complementary colour and red as the third colour.

www.tobuild.co.za | summer 2023

SUMMER COLOURS KITCHENS

DON’Ts: • Be afraid to add vibrant colour to your kitchen. Yes, that does seem to buck the latest kitchen trend of white and grey, but not every kitchen is the same. If you love colour and your kitchen would benefit from a pop of colour, try a fun accent wall. • Hesitate to use grey wall colours in your kitchen. Grey or grey-blue works beautifully for beach-style, colour schemes. Warm greys or ‘greige’ look gorgeous with dark cabinetry and flooring. • At the same time; a word of caution… Don’t overdo grey in the kitchen. Grey kitchens are a hot trend. It's easy to get caught up in the trend by choosing grey cabinetry, flooring, and counters. The fixed features of your kitchen will be around for many years, so consider using a grey wall colour or accents and keep one of the less-changeable features more neutral. • Forget that even adding colourful kitchen linens can change the look of the room inexpensively. Kitchen linens can be exchanged in and out with the seasons, and for a quick colour update. • Forget adjoining rooms in your colour scheme. You can add more colour by choosing an accent wall for an open dining area or family room. Tie the colour scheme together by sprinkling a little of the room's colours in the nearby space.

Can I break the 60-30-10 rule? Yes, if you're feeling confident and rebellious, you absolutely can. It is not a steadfast rule, merely a guideline to help those that feel overwhelmed with the choices available to them. Casting the ‘rules’ for interior styling and home décor aside; the end result is going to evoke feelings for you, so hone in and pay attention to how the space makes you feel. Your kitchen designer will be able to give you an overall idea of how your colour scheme would work with the marvellous 3D renders today’s design technology offers. If you are feeling like you have an idea or flair for colours, go with it! It may end up being something like 40-30-20-10 or 40-25-15-10-10 or even 75-15-10. Whatever the case, just make sure you focus on your percentages to help with balance, otherwise it may look wild and crazy! Hopefully if you were reluctant to add any ‘pops’ of colour, this advice will help to guide you and make colour in the kitchen that bit more accessible.

Using the colour wheel The colour wheel, sometimes called a colour circle, is a circular arrangement of colours organized by their chromatic relationship to one another. The colour wheel is used in the visual arts to represent the colours of the visible spectrum and their relationships to one another. The colours are arranged systematically in a circle, with each colour usually falling into one of three categories: primary, secondary, or intermediate. In fields such as painting, fashion, film, and design, artists use the colour wheel to assemble colour schemes and visualize how colours appear beside one another. The traditional painters’ colour wheel is one example of the subtractive colour system. Subtractive means that if you add these colour together, you are left with black. Its primary colours are red, yellow, and blue (hence, it is also called the RYB colour model, after the first letter of each primary colour). 42

Casalgrande Padana

In line with our high regard for il design Italiano, we thought to share some bathroom furnishing trends arising from Cersaie 2023. The featured product concepts and visuals come courtesy of manufacturer Casalgrande Padana, placing a strong emphasis on natural materials, hygiene and colour.

Bathroom design is no longer confined to a purely functional space; it has evolved into a sanctuary for relaxation and rejuvenation. As people seek to bring elements of nature into their homes, the use of natural materials in bathroom furnishings has gained global popularity. From rustic retreats to contemporary oases.

STYLES SUMMER COLOURS

Hygiene

The move to natural materials Incorporating natural materials into bathroom furnishings reflects a desire to connect with nature, create calming sanctuaries, and reduce the environmental impact of interior design. Whether you prefer the timeless elegance of wood, the enduring beauty of stone, the sophistication of metal, stoneware, marble, the modern minimalism of concrete, or the sustainability of bamboo, there's a natural material to suit your bathroom design vision. There is broad agreement that embracing nature in our bathrooms in respect of materials used, allows us to start and end each day in a space that truly reflects our values and appreciation for the world around us.

Although not new to civilisation, bacteria like to breed in wet spaces. Designers seem to have come up with an interesting solution: the incorporation of silver-based technology to help eliminate up to 99% of bacteria from the surface of bathroom tile surfaces, while also preventing stains and odours.

Colour More recently, washbasins, shower trays, and shelves can match the bathroom floors and walls for a seamless, cohesive look or create striking colour and pattern contrasts. A kaleidoscope of pastel colours enhances the beauty and natural feel of Italian designed products, for example the Casalgrande Padana porcelain stoneware tiles. According to the manufacturer, coloured floor and wall tiles are perfect for creating trendy combinations and styles: minimalist, classic, country or industrial chic. With the above in mind, the supplier suggests that its porcelain stoneware tiles can become the true star of the bathroom. The perfect combination of design and innovation emerges from the water, creating stunning textures, iridescent tones, harmonious transparencies, and sophisticated veining and colour variations. This collection, named Aquatio, was exhibited at Cersaie and is a good example of how washbasins, shower trays, and shelves can match the bathroom floors and walls for a seamless, cohesive look or create striking colour and pattern contrasts. As we continue to prioritize sustainable living and wellness in our homes, the use of these natural materials in bathroom furnishings is likely to remain a prominent design choice, offering a harmonious blend of beauty and eco-consciousness. Embracing nature in our bathrooms allows us to start and end each day in a space that truly reflects our values and appreciation for the world around us.

About Cersaie Held annually in Bologna, the Cersaie is the international trade fair for ceramic tiles, surface design, and bathroom furnishings and equipment in the realm of architectural design. Since its foundation in 1983, it has grown to be one of the leading trade fairs globally in its segment. With the 2023 event, its 40th, the show had 633 exhibiting companies from all over the world and 99,319 international visitors. Hence the Cersaie has confirmed its position as a ‘not to be missed’ event for design professionals and those working in the ceramic tile, bathroom furnishings and related sectors. Thus, from ceramic floors to wall tiles, floor and wall coverings of various materials, sanitary facilities, bathroom furnishings, fireplaces, and ceramic stoves to raw materials and equipment for ceramics, all find an exhibition home at this prestigious event. Attended by most South African manufacturers and suppliers of floor and wall tiles, as well as bathroom sanitaryware, the event is the meeting point between the creativity of design and the innovation of technical solutions, the place where those who want to immerse themselves in the inspiration, innovation and beauty of surface design and bathroom furnishings can enjoy a unique experience. Hence most of the SA design industry draws inspiration from this event.

SWIMMING POOLS

HOME

Whenever someone is considering an inground pool, we hope they do their research and understand the differences between them. If you’re looking for something different, you might want to consider gunite or vinyl liners. Is a fibreglass pool worth the investment? To determine whether fibreglass pools are right for someone, we recommend looking at their pros and cons. There is a misconception about this type of pool. Pools made of fibreglass aren’t any more slippery than those made of other materials. It is common for fibreglass pools to have gel coats with non-slip properties that still feel good when walking on them. Regardless of your pool type, accidents can always happen when water is involved, so be careful if you plan to wade in. Fibreglass is a long-lasting material compared to other pool types. Fibreglass pools are more resistant to cracking and algae growth, which means a longer pool life. As a matter of fact, gelcoat surfaces can last for decades. Nevertheless, future pool owners should be aware that the way the pool is maintained directly impacts its lifespan. When it comes to inground pools, fibreglass pools are considered to need the least maintenance. In spite of this, we must stress that low maintenance does not mean no maintenance. It will take less time, money, and effort each week to maintain this type of pool, but it will still require some time.

Did

Fibreglass pool manufacturers construct inground fibreglass pools using moulds in a factory setting. A number of different designs allows freedom of choice.

Be smart when going solar:

Here’s how

In the urgency to shield your household from the worst of loadshedding, you could end up with an investment that doesn’t deliver the promised returns. Here’s how to avoid the pitfalls when installing a PV system. Solar panels have become a feature of the South African residential landscape over the past few years as homeowners seek a measure of energy self-sufficiency. Once you have made your home as energy efficient as possible with LED lights, a solar, gas, efficient geyser, gas cooker and energy-saving habits, the time is right to invest in a PV system with battery backup to keep you going during loadshedding.

summer 2023 | www.tobuild.co.za

It is always a good idea to know what your monthly electricity consumption is in terms of kilowatt hours, this will be asked of you by any installer worth his or her salt. You can find this on your electricity bill, and it would be a good idea to compare what you were using before your energy efficiency interventions versus what you are using now. Once you know what you are consuming you will also know whether or not the installer is quoting you with specifications that will meet your needs.

“How much can I expect to pay for a PV system and will the ROI be worth it, are questions I get asked often, quickly followed by what can I do to not get taken for a ride,” says Dr Karen Surridge, Renewable Energy Project Manager of the South African National Energy Development The answers Institute are not simple, (SANEDI). but the guidelines g provided will go a lon ng uri ens way towards a happy PV and/or battery system investment.

SOLAR POWER HOME

Find the right installer

The starting point is a reputable installer with a solid reputation and good references. You can find installers in your area registered with the South African Photovoltaic Industry Association (SAPVIA) on the PV GreenCard website (www.pvgreencard.co.za). Registration means that the person has had the proper safety and quality training and will issue you with proof of compliance for the installation for insurance, finance and regulatory purposes. You can also Google your potential installers and ask friends or social-media community groups for references, word of mouth can be a powerful recommendation. A certificate of compliance (CoC) as a line item on your quote is usually an indication of capability, since only registered tradespeople can issue such a document.

Know what you should be paying for

A PV system consists of PV panels, an inverter, batteries and the components that tie the system into your home’s electrical system. The quote from your installer should be itemised and specify all these items. • The inverter inverts the direct current (DC) produced by the PV panels (or batteries) into alternating current (AC), which makes the electricity available to your home and appliances. An inverter on its own is of no use. Never skimp on the inverter and always choose one with a built-in surge protector. While prices differ, a good 5 kVA inverter that is sufficient for an average four-person household should cost between R25 00 and R30 000. • In terms of photovoltaic (PV) panels, go with a well-known brand that has a good reputation. Insist that the installer specifies the brand they intend to use so that you can do your own research. Nowadays, PV panels have a relatively high efficiency of about 20% and it is usually a 545-555 watt panel that you will purchase. You are looking at a price range of approximately R2 000 to R4 500 per panel. For an average household,

with a family of about four, 8 of these panels should be more than enough. Once again do your research, make sure that you are satisfied with the specifications for that brand of panel, for which you are quoted. • When it comes to batteries, there are a number of options from which you can choose, however, there are two factors that you need to consider: the first one is the depth of discharge (DOD) and the second one is the number of cycles in the lifespan of the battery. o Ideally, if it suits your pocket, Lithium Ion (LIB) should be your battery of choice, but it is the most expensive, coming in at about R25 000 to R30 000 for a 4.8kWh total capacity

when paired with your 5kW inverter. They are more energy dense than lead acid or gel batteries, meaning they last longer (up to 3000 cycles) and have a deeper cycle discharge ability. In layman's terms this means that a lithium ion battery can comfortably go down to from 5% to 20% depth of discharge meaning 80% to 95% of its capacity can be used to supply the household's power needs without greatly degrading the lifespan of the battery. o In terms of cost vs depth of discharge (DOD) and cycles, the next best option is to consider gel (deep cycle) batteries. One would expect to pay around R4 000 to R7000 for a 3.2kWh www.tobuild.co.za | summer 2023

HOME SOLAR POWER

pack at 12v. These should only be run to 50% discharge, anything beyond this and you will risk negatively affecting their lifespan (100 to 1500 cycles). o Similarly, deep cycle (gel) lead acid batteries should be discharged to no lower than 50%. Never fully discharge a deep cycle lead acid battery because the deeper you discharge the battery the more it will reduce the battery's total lifespan (500 to 1000 cycles). Lead acid batteries are the least cost to buy and prices range from R3 000 to R7 000 for a 3.2kWh 12v battery. pack. (Ed. practical experience, backed by science shows that a nano enhanced flooded battery is the best option if you go with a lead acid power source). • Whatever battery you select, insist on a brand name that you know or can research, both in terms of performance and price, and look for the warranty period. That is a dead giveaway. • Request an itemised quote for all the components needed to get the electricity from the panels into your home. These include roof brackets, wiring, the combiner box (which sits between your home distribution board and the rest of the system), solar charge regulator if not integrated with the inverter, the inverter unit itself, labour costs, the certificate of

summer 2023 | www.tobuild.co.za

compliance (CoC), switches, cables, fuses where used (it is always good to have a few of these kept in reserve, they are inexpensive) and trunking. • Switchgear and surge protection, the “brain” needed to balance the system, must also be specified, along with the level of tech integration that is offered. • Lastly, don’t be seduced into buying functionality or capacity you might not use; remember you are energy efficient now so you don’t need such a large system. Things such as wi-fi communication are also nice-to-have, but not essential. “It is important to get a spec for the wattage on the inverter, panels and batteries,” says Surridge. “You sometimes need a few more panels than you’d think (typically 30% more - Ed), and you never want to run your inverter at its maximum. For example, if you have 2.8 kW coming in from the panels, you want a 5kW inverter. In this way, you don’t put strain on the inverter, which extends its lifetime. As far as possible, you want your inverter to last the life of the system.”

Negotiate

Just because your installer is reputable, it does not mean you should accept their quote. Get a few quotes and negotiate if you feel it is unreasonable, but without skimping on either quality or safety for the equipment, safety for your home electrical system and safety for you and your family. “A PV and/or battery UPS system can add tremendous quality to your life and up the resale value of your home. It is therefore worth investing the time and effort to make sure you get the best value for your investment,” concludes Surridge.

INSULATION FEATURE

State of the

‘insu-nation’ South Africa is fortunate to have an industry association, TIPSASA (www.tipsasa.co.za), representing the interests of manufacturers, installers and the customer. As with any industry servicing construction, there is a need for standards and quality assurance. Des Schnettler of TIPSASA shares some notes with readers covering the prevailing insulation landscape in South Africa. Des Schnettler

TIPSASA & Technopol SA Progress and challenges with fire test methods In 2013, the Thermal Insulation Association of Southern Africa (TIASA), now TIPSASA, voted in favour of adopting the European fire test methods and classification. In 2014, the SABS adopted the test methods, i.e., EN 1182 (SANS11820), EN 1716 (SANS1743), EN 13823 (SANS 53823) and EN 11925-2 (SANS 11925-2). The classification EN 13501-1 (SANS 53501-1) was only adopted in 2018. In 2021, the revision of SANS 10400 Part T Fire Protection commenced. Ten years later the proposed changes are finally being incorporated into the revision of SANS 10400-T. The SANS 53501-1 classification comprises three ratings. The first is the main class rating, which will be the letter A1, A2, B, C, D, E or F. The highest level of performance is A1, while F is the worst. A1 products are classified as non-combustible. A2 products are classified as limited combustibility, and B to F are classified as combustible in ascending order. The second classification relates to smoke emission during combustion. This is indicated by a rating of s1 (absent or weak), s2 (average intensity) or s3 (high intensity). Smoke emission classifications are not provided for products with an E or F overall rating. The third classification relates to the level of production of flaming droplets/particles during combustion. This is indicated by a rating of d0 (no dripping), d1 (low dripping) or d2 (high dripping).

SANS 8414 Test method for external cladding and ETICS. So far only one SA company has successfully tested their system in accordance with the new standard.

External Thermal Insulation Composite System External Thermal Insulation Composite System (ETICS) became popular with the introduction of energy efficient buildings. However, in 2017 we saw what could go wrong with the horrific Grenfell Tower fire in West London when the entire façade of the building was engulfed in flames in 4 minutes and 20 seconds. Seventy-two people lost their lives, 70 were injured and 223 managed to escape. Subsequently there have been several other cases where similar fires have taken place. Even though there have been fire standards in place, this was disregarded by contractors with terrible consequences. South Africa did not have the proper fire testing standards in place for ETICS and this has now also been addressed with the introduction of BS 8414 Parts 1 and 2 in the revision of SANS 10400-T. The fire safety of the external insulating or cladding system, which is either fitted to the structural external wall or frame, must comply with the requirements for temperature, flame spread, mechanical failure such as flaming debris and debris falling during the evaluation of the system when tested in accordance with SANS 8414, Part 1 and Part 2. To our knowledge there is currently only one company that has successfully tested their system in accordance with the new standard.

Energy efficiency legislation compulsory since 2011 Buildings are a major source of energy consumption and greenhouse gas emissions globally. The Department of Trade and Industry published an amendment to the National Building Regulations in 2011 to introduce requirements for energy usage in buildings.

Roofs are exposed to both high solar radiant heat gains in summer and high heat losses during winter nights.

This regulation “Energy usage in buildings”, was promulgated on 9 November 2011. All new buildings and extensions have to comply with the new regulation. Roof assemblies, i.e roof covering materials such as tiles or metal sheeting, ceilings and added insulation, are required to meet a minimum total thermal resistance as specified for the various energy zones. Roofs are exposed to both high solar radiant heat gains in summer and high heat losses during winter nights. The roofceiling combination therefore warrants special attention from a thermal point of view. Unfortunately, most South Africans still do not understand the benefits of thermal insulation products used in the construction of buildings.

South Africa’s annual solar radiation is double that of Europe and the UK combined. It has been proven through research that insulation does have an impact on the buildings’ energy performance. It is a regulatory requirement to specify thermal insulation in buildings. Unfortunately, some developers and contractors still do not comply, either not installing insulation at all or changing the architect’s specification to save on cost. Not only is this against the law but also a serious fire risk.

Status of compliance and quality in South Africa Product testing according to the relevant product standard is voluntary according to the South African Bureau of Standards (SABS). The only exception is when it is www.tobuild.co.za | summer 2023

INSULATION FEATURE

referred to in the National Building Regulations, then it is compulsory as is the case with fire (SANS 10400-T Fire protection) and thermal performance (SANS 10400-XA Energy usage in buildings). Generally, there are few manufacturers that actually comply with product standards, they only comply with the regulatory requirements. Traditionally, the SABS provided an extensive array of testing and certification and once the product met the SABS product standard requirements, certification was awarded, i.e., the SABS “Mark of Approval”. There is a misconception in the industry that the SABS mark of approval is mandatory, but it is not. It is a prestigious marketing tool awarded (and additionally paid for) once products comply with all the performance requirements in accordance with the relevant test standard. Few people are aware of the changes at the SABS. The South African Bureau of Standards is the national body responsible for standards in South Africa. Testing is now done by SABS Commercial (SOC) Ltd, a separate entity registered in 2000 via an Act of Parliament. Testing is no longer exclusively “in house” but often outsourced to private laboratories as testing equipment is either out-dated or non-functional due to financial constraints and a lack of resources.

Easy access of compliant products As a result of inconsistent or questionable test results, the Thermal Insulation Products & Systems Association (TIPSASA) has taken the decision to support any independent SANAS accredited testing laboratory. Information from members regarding compliance with product test standards will be verified by TIPSASA and published on the official website. A Certification of Compliance will be issued by the Association to assist professionals. 56

How NOT to do a blanket insulation installation.

Barriers and opportunities to achieve compliance Contractors changing specifications to “save” on costs! Once an architect has specified a product and the plans have been approved by the local authority it is an offence in accordance with Regulation A25 to change any particulars approved, unless the deviation has been approved by the local authority. It is also the responsibility of the professional to inform the owner of the building that certain decisions (such as changing to “similar but cheaper” products) might lead to non-conformity with legal requirements: Fortunately, the Consumer Protection Act No 68 of 2008 (CPA) took effect in South Africa on 1 April 2011. Strict liability is introduced in section 61 of the Act. It states that any producer, distributor, or supplier of a product/system is strictly liable for any damage caused wholly or partly because of a product/system failure, defect, or hazard in a product/system or as a result of inadequate instructions or warnings provided to the consumer pertaining to any hazard. Testing of products or systems and accurate records are therefore an absolute necessity to provide proof that the product or system is safe and suitable for its application. TIPSASA was instrumental in the development of the Insulation Installer qualification registered with SAQA (the South African Qualifications Authority). Training is provided by independent service providers registered with the Association. Once qualified, installers can register with TIPSASA as an “Accredited Insulation Installer”.

Alleviating national energy poverty Environmental challenges require high building envelope performance requirements, hence the publication of SANS 10400-XA Energy usage in buildings. In addition, it can also alleviate national energy poverty. The assessment of actual energy performance of buildings will be mandatory in 2025. Energy Performance Certificates (EPCs) must be prominently

displayed in offices, entertainment facilities, educational institution buildings and places of public assembly such as sporting facilities and community centres. The regulations apply to government buildings of more than 1 000m² and privately owned buildings of more than 2 000m². If you have any questions, e-mail Des Schnettler at info@tipsasa.co.za

Cellulose fibre offers huge insulation benefits

Thermguard cellulose fibre insulation was developed locally over 40 years ago, based on winning technologies from Europe, North America and elsewhere, with some local improvements. Driven by sustainability and quality, its manufacturing plant is ISO 9001:2015 rated. Thermguard celebrates World Standards Day, held on 14 October every year. In this overview, the company discusses its contribution towards standards, passive climate control and energy efficiency.

Compliance and environment Thermguard wholeheartedly embraces compliance issues. For example, Conformity International (CI) recently updated and renewed the product’s certification within the scope of SANS 1381-6:2011 (materials for thermal insulation of buildings) cellulose loose fill thermal insulation material. We also meet the energy efficiency specifications of SANS10400-XA:2021; in fact, we exceed them in most cases when correctly installed. Thermguard is troubled by the trend in the industry in which manufacturers pay mere lip service to safety and performance standards, focussing only on regulatory requirements, namely SANS10400-XA, the Energy Usage in Buildings Regulation and SANS 10400-T Fire protection. As an active founding member of the Thermal Insulation Products and Systems Association of SA, Thermguard proudly holds their Certificate of Compliance. The rapid advance in climate change is of concern to Thermguard, so it constantly researches to enhance its contribution to a low carbon future. 58

INSULATION

Safety One of the casualties of the prevailing “minimum compliance” trend is the certified fire rating for insulation products installed in buildings, especially among installers. Architects’ specifications are frequently brushed aside when it comes to the final stages of a new build - often when insulation is installed. Thermguard is fire-retarded and classified under SABS10177 as Class B1; i.e., it will not cause the spread of flames in the case of fire in a building. But Thermguard goes further than that as its performance is at a higher level. Anecdotally, having cellulose fibre insulation in the roof can actually save the building in the case of fire. This is superbly demonstrated in a video shot a number of years back by the Maryland Fire & Rescue Institute1, which erected three test

No spread of fire.

‘houses’; two insulated with a different material and one uninsulated. The buildings were set alight and after 67 minutes the only building standing was the one with cellulose fibre in the walls and roof. Locally, one of Thermguards’s most experienced distributors was recently unlucky enough to have a fire in the roof of his home. He noted that the blanket of cellulose fibre insulation in his ceiling actually prevented the fire from spreading further into the home. Despite damage to the upper sections of the roof and some trusses, the house and its occupants remained safe. Thermguard recently conducted a graphic test at the factory to demonstrate fire retardancy. A small sample of the product was held by hand and exposed to a 1500ºC gas torch flame. Despite the product burning on the surface while the direct flame continued, the body of insulation failed to ignite, immediately self-extinguishing once the flame was removed.

Regulation compliant insulation has a huge impact on a building’s energy performance.

It has been proven through research that, correctly installed, regulation compliant insulation has a huge impact on a building’s energy performance. Thermguard promotes the use of recycled natural materials for home and office insulation in South Africa, with all the benefits that it offers: People, Safety and Planet = Sustainability.

STEEL AWARDS 2023 MATERIALS & SUPPLIERS

SAISC steel awards

shine a steely light

The 2023 Steel Awards, presented by the Southern African Institute for Steel Construction (SAISC), inspire steel value chain collaboration between architects, designers, engineers and construction companies, say the organisers. SAISC Representing the best of South African built environment projects using steel, the most outstanding entries were on show at the annual showcase organised by the SAISC. The 2023 event highlighted the delivery of world-class projects across the African continent. The 2023 red carpet awards event, which took its theme from popular and long enduring HBO series, Game of Thrones, provided an opportunity for stakeholders across the industry and steel value chain, including designers, architects, engineers, processors, merchants and fabricators, to

present their work and be honoured for their outstanding achievements. “As we hear news of horrible wars, earthquakes, competition for resources, scarce energy, and more, we must remember that we are the people who figure out how to build the steel structures that can withstand blasts, resist earthquakes, dig out and process the resources of the earth and build power plants. We are literally in the business of creating the Iron Throne,” said SAISC Chief Executive Officer, Amanuel Gebremeskel, in his keynote speech at the event held in Gauteng on 19 October.

“There is little question that the South African industry punches well above our weight. This was obvious during our trip to Canada for the biennial International Steel Contractors Group meeting last month. “The challenges that our industry and institute face in SA are significantly more complicated than any of our global contemporaries. Our resources to overcome those challenges are a fraction of what they have available to them. However, it is not an exaggeration to say that our colleagues are mighty impressed with what our institute, your companies and our local universities have achieved.” Of particular interest to the judges this year was that many of the notable projects nominated were not confined to South Africa, but exported, and in some cases executed, across the continent. This was reflected in the number of Pan-African projects which won awards, and indicated that one of SAISC’s long-held goals is being realised. “Fabricators and manufacturers have really forged ahead and made a big leap into Africa! They have built structures in a way that has never been done before, delivering products and innovations which have never been seen before – not only locally but across the continent,” said Gebremeskel.

The main challenge was the sheer size of the roof structure and its structural framing system, which posed a significant logistical challenge to transport from the Kempton Park fabrication site to the market site over 300km away in Mbombela. To address this challenge, modular components were transported in smaller sections and then erected on site. Fitting all the pieces of this Meccano-like construction in a seamless and cohesive manner was a huge achievement. These challenges were overcome by carefullydesigned jigging systems used for the fabrication of the components, and then trial assembling the major structural components and interfaces between them. Mpumalamga Fresh Produce Market.

Fresh and fabulous: the overall winner The Mpumalanga International Fresh Produce Market is not only the Steel Awards 2023 overall winner, but also garnered three category awards as winner in the Factory and Warehouse category, the Tubular category and recipient of the Best Regional Project Mpumalanga Award. Nominated by Tass Engineering, the project was designed by Orbic Architects and constructed by (amongst several others) the main contractor Enza Construction and steelwork contractor Tass Engineering.

This so-called ‘market of the future’ was constructed for the Mpumalanga Economic Growth Agency to act as a regional catalyst for growth, creating jobs and improving food security. Serving the local and international food industry, it is more effective and efficient than existing, traditional fresh produce markets. The steelwork roof covers a 29 000m2 floor and is designed to provide maximum usable floor space with minimal support columns. The building was also designed to accommodate future alterations and expansion.

A record-breaking distribution centre Structural steel, roofing and cladding also played a pivotal role in the Pick ‘n Pay Distribution Centre Eastport project, the joint winner of the Factory and Warehouse category, winner of the Innovation and Sustainability category and recipient of the Best Project Gauteng Award. One of the stand-out features of this exceptional project is the use of extremely long roofing sheets, ranging from 68 metres to a staggering 280 metres. These unprecedented roof sheeting lengths required innovative solutions for handling and installation, ultimately earning the project a place in the Guinness World Records. “This is a phenomenal innovation, and a lot of work went into it. It is very nice to see one of our established, older steel companies showing a lot of vigour and energy. We have really achieved world leadership in sky-rolling capabilities. This is not only a notable project in South Africa, but globally,” Gebremeskel commented.

Also impressive is the fact that the engineer who designed the structure came up with a very elegant solution for the problem posed: the need for a lot of column-free space. “To solve this, an arched roof was used along the entire 220-metre length, supported at each end using a structural framing system. The aesthetics and project execution, including the engineering, connections used, the seamlessness thereof and how the structure was erected, is quite amazing and a testament to the power of structural steel as a material of construction,” Gebremeskel said.

A praiseworthy achievement in Chad The third project Gebremeskel highlighted is the Our Lady of Peace Cathedral in N'Djamena in Chad, the winner of the Light Steel Frame Building category. Conceptual design to restore the cathedral started in March 2014, and addressed wind-load considerations through the implementation of a specialised shell structure design employing custom-made brackets to securely anchor the light-weight steel to the concrete structure. This remote Central African project location required on-site fabrication. A number of logistical challenges had to be overcome due to the absence of nearby ports and limited road infrastructure suitable for container transport. The entire project also had to be successfully delivered during a period of political instability in the region.

Although mining projects, and especially those in remote locations, are inevitably the largest, he observed that large retail distribution centres have also grown tremendously in size, and are also aesthetically more interesting. “The SAISC is very grateful to the Steel Awards judges, who have given their own time to contribute to the industry that they love. The SAISC also thanks all stakeholders who worked to make the awards a success – and the generous sponsors,” he added.

Timber Decking Structure Regulations and Preservative Treatment It is important to use properly preservative treated timber in the construction of substructures for timber decks and its compliance with the requirements as stipulated in the Building Regulations and relevant SANS Standards. An important factor often overlooked when installing a deck, is the substructure on which the deck is being built. Most of the attention and thought generally goes into the upper decking material, and not into the loadbearing structure that is going to carry the load, and its demanding exposure to the elements. As a result there have been numerous failures due to unscrupulous contractors using material not capable of enduring the elements.

In most cases the material, e.g. the upright poles/posts planted into the ground are of acceptable preservative treated quality (H4 to H5) but the horizontal beams and bearers are often constructed of untreated or insufficiently (H2) preservative treated structural pine, whilst the upper decking itself consists of correctly preservative treated pine (H3) or hardwoods of varying natural durability. Any moisture, whether from precipitation or irrigation mechanisms will accumulate between the intersecting upper decking boards and load bearing beams, causing a moisture trap and forming the perfect environment for fungal decay. If the load bearing beams and bearers used in the substructure are not made up of at least H3 treated structural pine, the rate at which decay could set in and lead to failure of the deck structure may be rapid and could lead to injury for those walking on the deck.

www.sawpa.co.za

F o

Decks are regarded as loadbearing structures and buildings on which people walk and gather and as such it must be designed and constructed in accordance with the Building Regulations and relevant SANS Standards. The Building Regulations, in specifically regulation A13 (1) (b) stipulates that “All timber used in the erection of a

building shall be treated against termite and wood borer and fungal decay in accordance with the requirements of SANS 10005 and shall bear the product certification mark of a body certified by the South African Accreditation System”.

SANS 10005 in clause 12 addresses the use of preservative treated timber in specific areas of South Africa and the qualification the two main species, i.e. softwoods and hardwoods, of being adequate for its purpose as structural loadbearing components used in a permanent building. In 12.2 it deals specifically with use of preservative treaded softwoods (pine) mainly focusing on the use in the coastal municipal areas, but in the last paragraph clearly states;

“Sawn timber used in the erection of an exposed loadbearing structure, i.e. the substructure of decks, shall be treated in accordance with 12.4 when used within the borders of South Africa.” This reference specifically addresses the protection of all decking loadbearing substructures constructed of softwoods against fungal decay and subterranean termite attack, not just in the coastal municipal areas, but in all inland areas. This means that a deck substructure constructed with untreated or incorrectly treated timber does not comply with the Building Regulations.

H6 Ͳ High Hazard: Prolonged immersion in sea water (jetty crossͲbracing and pilings, landing steps, retaining walls etc)

H5 Ͳ High Hazard: Fresh water/heavy wet soils (poles used in jetties & walkways, foundation piling, agricultural poles under irrigation and fertiliser e.g. vineyards, etc).

Over the years , says the CMA (www.cma.org.za), it has commissioned several independent surveys that demonstrate how concrete roof tiles outperform alternative materials across critical performance criteria. Recently, CMA member company, Port Elizabeth’s Eagle Roof Tiles, commissioned its own cost comparison study between erecting a concrete tile roof versus a corrugated metal roof. The company has had a longstanding relationship with the CMA and uses its certification arm, CMACS, to certify Eagle’s tiles which are produced to SANS 542 specifications. “We focus on three Cs when comparing the performance of concrete roof tiles with metal-sheeted roofing: cost (initial cost and maintenance), comfort (peace of mind, thermal and noise dampening performance) and creativity (style and beauty),” says Tarn Derman, General Manager of Eagle Roof Tiles.

ROOFING

Cost studies “We decided to revisit the cost aspect in an updated appraisal and to that end we commissioned an ITC SA certified truss fabricator, Africa Timbers, to run a comparative cost study between a concrete tile roof and a metal sheeting roof in September 2023,” says Derman. Africa Timbers followed a commonly used roof design to allow for the most accurate and fairest cost comparison. The use of MiTek design software validated the engineered design and material costs of both roofs. The costing exercise covered complete roof structures from the wall plates and above, but excluded fascias and bargeboards.

The study was based on an average-sized house of 161m² with an intersecting gable and hip-roof design pitched at 25°. Double Roman through-colour roof tiles and 0.47 corrugated sheeting F/H, the cheapest acceptable sheeting for this type of house, were the two materials chosen for the comparison. The 2023 total cost for the metal roof was R154 748.38, comprising R76 468.34 for roof trusses and fixtures and R78 280.04 for the roof sheeting. The total cost for the concrete tile roof was R116 216.34, comprising R88 254.97 for roof trusses and fixtures and R27 961.37 for the concrete tiles. “This represents a substantial saving of just under R40 000, or 33% less for the concrete roof tile house, an amount which could be used towards countering load-shedding or to contribute to a child’s education,” Derman comments.

“It is clear from the above that concrete roof tiles are the most economical roof cover and the savings will be even greater over the lifetime of the roof as the maintenance on concrete roof tiles is virtually zero. “A major comfort factor with concrete roof tiles is the associated peace of mind in knowing that they almost never have to be replaced. Since they were first introduced to the South African market over 70 years ago they are still protecting homes with minimal fuss. Due to their large thermal mass, they absorb high levels of energy when it is warm and then slowly release the accumulated heat at night when it is colder, ensuring a comfortable interior,” says Derman.

Covered with Eagle Roof Tile’s slate tile, modern elegance gives way to crisscrossing angles and framed gables at The Waves in Wilderness, Western Cape.

Thermal efficiency In order to prove that concrete roof tiles are considerably more thermally efficient than metal sheeting, in 2012 the CMA commissioned the AAAMSA Group to run a series of tests comparing the thermal performance of metal sheeting roof with a concrete tile roof. One of the tests, which involved roofs with ceilings, revealed R-values of 0.38 for the metal roof as against 0.49 for the concrete tile roof, a 29% comfort factor improvement. “Concrete roof tiles are also vastly more efficient noise insulators. Metal roofing, especially when used in working environments such as schools and government buildings, have to be installed with far more insulation material to damp down noise from rain, hail and wind to reach tolerable levels,” Derman explains.

One of the Western Cape’s most-loved concrete roof tiles, Eagle Roof Tile’s Shingle profile lends itself to the sharp triangular lines on this exposed intersecting gable roof.

“Creativity with concrete roof tiles is only limited by one’s imagination and really broadens one’s design horizons. Tiles can be cast in innumerable colour choices for enhanced beauty and they allow designs with hips, gables, mono or duo-pitch, modern or traditional which add individuality and value to any house. They are definitely the best roofing material available, and can convert any house into a home,” he adds.

Concrete progress Colossal Concrete Products reopened its mothballed De Aar factory in October. This is very positive news for the Northern Cape, where a boost in economic activity is much needed. The investment needs to be seen in the light of the June 2021 acquisition of Aveng Infraset’s Brakpan and De Aar precast by a consortium made up of Colossal Africa Group, Mafoko Holdings, Clone Capital and Randvest Capital concrete manufacturing facilities. CCP

This eagerly anticipated move follows the recent conclusion of a one-year contract with Transnet Freight Rail (TFR) to supply precast concrete railway sleepers for the parastatal’s national freight rail network upgrade. The De Aar facility is strategically located in the Northern Cape, near one of the arterial railway junctions connecting the Cape Town,

Johannesburg and Kimberley lines. Through its manufacturing facility reopening, the company will not only provide a much-needed boost to the regional economy through the creation of jobs, and additional upstream and downstream manufacturing and supply opportunities, but is now in a position to reach its inherent capacity, with the production of over 1 million railway sleepers per annum.

“In line with our precast concrete manufacturing capacity, skills and our Pan-African growth strategy, Colossal can play a significant part in the rollout of rail, civils and general infrastructure development, improving the overall prosperity of the continent. The TFR contract has been the catalyst for the reopening, and there are now further plans to keep the operation sustainable.,” Mahuma-Madida explains. She says that the acquisition of an adjoining property in De Aar will also assist in growing the company’s footprint within the renewable energy space. The De Aar facility is close to the current Northern Cape hub of many renewable energy projects and is expected to be pivotal in supplying products such as precast wind turbine towers, amongst others.

Concretising job creation “De Aar, like many areas in the Northern Cape, has been economically depressed in recent years. It is with this in mind that one of the most important elements in the rejuvenation of the manufacturing facility is the creation of some 50 jobs,” says Executive Director Chris ‘CK’ Klagsbrun. “No employment opportunities have been available since the plant was mothballed by the previous owner over three years ago, and we have been inundated with job applications. We are also collaborating closely with the local mayor and municipal manager, who are extremely excited about the plant reopening and what this means for the town as a whole.“ Jobs that will be created include mixer operators, team leaders, boom scraper, line feeder, crane operators, boiler operators, wire feeders, forklift drivers, grinder operators, wire cutters, slot washers, preppers and quality controllers.

“Preference is being given to those previously employed in the above positions at our De Aar facility, and I am confident that a fair percentage of former employees will be re-employed,” he advises.

Currently, Colossal Concrete Products is recognised internationally as one of the world’s most innovative and diverse concrete sleeper producers, with a highly experienced research and development division having developed over 40 railrelated products.

“Our vision is to constantly bring innovative new solutions to the rail, mining, renewable energy, civil engineering and construction sectors, among many others. Taking this a step further, we also plan to replicate what Colossal does across Africa. We have already grown our consulting division close to home; and we are working closely with our Swedish partner on Pan-African rail projects. There have been recent enquiries around establishing new manufacturing plants which we have participated in, where Colossal could either oversee construction or conclude service level agreements to manage these facilities,” Klagsbrun explains.

In addition, Colossal manufactures other precast concrete products including culverts, poles and masts, for use in the mining, civil engineering, construction and renewable energy sectors, to name but a few. There are also plans to manufacture wind turbine towers moving forward.

As the company is a major player in the precast concrete space supplying the mining, construction, civils and general infrastructure sectors, Mahuma-Madida says every Colossal facility will always produce a variety of products servicing multiple sectors.

“We are still the only company locally that has such a large range of railway products. To retain that leadership position is critical. While our competitors do manufacture a selective range of main line sleepers, we are the only ones to make the entire range,” adds Mahuma-Madida.

“Not only is the De Aar plant strongly positioned for projects in the renewable energy space - but it is strategically and operationally well placed to fill the gap left by the closure of companies serving the construction sector in the Northern Cape,” she concludes.

PPC new blending plant

ensures security of cement supply PPC officially launched its new blending plant in the Highveld region on 1 August. The new facility is in the old Highveld Steel Industrial Park in Emalahleni Local Municipality. It stands as one of the cornerstones in PPC's commitment to bring about enhanced efficiencies, improved turnaround times, outstanding customer service, and exceptional quality to all built environment stakeholders in the Highveld region.

The Highveld PPC plant is strategically positioned to serve the thriving construction and building industries in and around the Mpumalanga and Limpopo regions. Previously, serving this region required long-haul transport from Gauteng, posing inefficiencies for both PPC and its customers.

Optimising logistics through localisation "The opening of this Highveld plant allows us to optimise our logistics through localisation, which is imperative in reducing transport costs and minimising transportinduced carbon emissions," said Bheki Mthembu, Head of PPC’s Inland Business Unit. Apart from the logistical efficiencies, the new plant will actively contribute to PPC's broader decarbonisation goals. That’s because it achieves lower overall CO2 emissions per tonne of cement through operational efficiencies and the optimum application of fly ash, reducing the clinker content – typically an emissions-intensive component – in its cement.

PPC can now make smaller delivery runs The plant also stands to be a game-changer for small contractors and entrepreneurs in the region. It will enable PPC to make smaller delivery runs, upwards of 12 tons (240 bags), and facilitate so-called 'milk runs' where a single truck serves multiple customers in one trip, thus catering to micro-enterprises that previously could not afford large material loads. Mthembu says that PPC’s commitment to giving more South African builders and their clients the benefit of access to the highest quality cement products at affordable prices was one of the key drivers behind its decision to establish the Highveld plant. “PPC has an enviable reputation for trusted, quality products that conform to all regulatory requirements in our industry,” he explains, “and we are excited by the opportunity this new plant affords us to make this quality readily available to industries and people in the Highveld region.”

Positive implications for local communities The establishment and operation of the new PPC Highveld plant also have positive implications for local communities. The construction and development process delivered 31% direct and an estimated 69% indirect temporary employment opportunities. Also, while a blending plant is a highly automated operation, it requires little manual intervention. The plant operations will also have a positive knockon effect on local businesses that form part of its supply chain or deliver various services such as transport and maintenance. Despite only officially opening on 1 August this year, the PPC Highveld plant is already operating at around 68% of its full capacity, with outputs projected to increase monthly as awareness of the operation spreads and demand for PPC’s top quality, locally blended products continues to grow. “PPC has long been a trusted name in the cement industry, offering our range of world-class products across a wide geographical footprint. We are excited about the opportunity this new Highveld plant affords us to extend this strategic commitment and expand not only the reach of our products but also the positive role PPC plays in underpinning South Africa’s vital construction sector as well as the country’s economic growth.”

CONSTRUCTION LEGAL

Alternative dispute

resolution for contracts In the pressurised world of construction, contracts regularly fall into dispute between affected parties. Alternative dispute resolution is often the best option when in a dispute, argues experienced legal practitioner, Bryan Hack. This is backed by important and relatively recent changes to the Uniform Rules of Court in South Africa. Adv Bryan Hack

Bryan Hack

Even South Africa’s Department of Justice says alternative dispute resolution is the best option when in a dispute. The Rules Board1 amended the Uniform Rules of Court, which regulates proceeding in the High Court of South Africa by the inclusion of a new Rule 41 A on 9 March 20202. This has introduced an important requirement that all litigants must be aware of and with which all litigants must comply. It requires everyone to consider the possibility that the dispute that they wish to bring to a court of law could maybe be determined and settled by mediation. The rule states that all litigants with a dispute must consider mediation, which means a voluntary process entered into by agreement between the parties to a dispute, in which an impartial and independent person, the mediator, assists the parties to either: • resolve the dispute between them, • or identify issues upon which agreement can be reached, • or explore areas of compromise, • or generate options to resolve the dispute, • or clarify priorities, by facilitating discussions between the parties and assisting them in their negotiations to resolve the dispute. To give effect to this rule the law now requires that in every new action or application proceeding, the plaintiff or applicant shall, together with the summons or combined summons or notice of motion, 72

summer 2023 | www.tobuild.co.za

serve on each defendant or respondent a notice indicating whether such plaintiff or applicant agrees to or opposes referral of the dispute to mediation. Equally a defendant or respondent must, when delivering a notice of intention to defend or a notice of intention to oppose, or at any time thereafter, but not later than the delivery of a plea or answering affidavit, serve on each plaintiff or applicant or the plaintiff’s or applicant’s attorneys, a notice indicating whether such defendant or respondent agrees to or opposes referral of the dispute to mediation. The rule requires that each party shall clearly and concisely indicate the reasons for such party’s belief that the dispute is or is not capable of being mediated. The rule goes on to stipulate that where a dispute is referred to mediation, the

parties shall deliver a joint signed minute recording their election to refer the dispute to mediation. The consequence thereof is to stay the court proceedings until the mediation is concluded. The rule further stipulates that it must be concluded within 30 days from the date of signature of the minute. Only after the mediation is concluded and there remains any issue in dispute, the parties may then proceed to litigation on such issue. The rule provides that the parties who engaged in mediation and the mediator who conducted the mediation must within five days of the conclusion of mediation, issue a joint minute indicating whether full or partial settlement was reached or whether mediation was not successful; and the issues upon which agreement was reached and which do not require hearing by the court.

LEGAL CONSTRUCTION

Liability for costs incurred In addition, it is also stipulated by the rule that unless the parties agree otherwise, the liability for the fees of a mediator shall be borne equally by the parties participating in mediation. The introduction of this rule has introduced to the beginning stages of litigation a procedure already followed but only at a significantly later stage. Up to the introduction of the rule, parties would potentially spend a significant amount of time and financial resources before being able to bring a matter to a trial by a management judge. Only at that stage were the parties expressly required to consider the possibility of mediation, either of the entire dispute or at least of any material aspect of the dispute. The new rule provides that that requirement must already be adhered to at the very start of proceedings before the lengthy and expensive process of exchange of pleadings and other formal stages of litigation take place. This is a very salutary and wise change in the rules. It requires legal representatives to put the possibility of mediation, or for that matter any other form of alternative dispute resolution, such as arbitration, to the clients and to formally file a document showing that they have considered mediation and whether such a process is viable or possibly not. One can expect that judges will require cogent reasons as to why a litigant has refused mediation, in particular, when his or her opponent is prepared to go down that pathway .

Recent precedents Recent judgments which have addressed the new rule are: • Nomandela and Another v. Nyandeni Local Municipality and Others 2021 (5) SA 619 (ECM) In this case, the court held that it is not to be underestimated that the rules are meant to be complied with. However, the court added it has been stated often by the courts that the rules are meant for the court, and not the other way round.

It is ideal that in the near future litigants should comply with this rule. That would ease the congested court rolls and achieve less costly and speedier resolution of disputes. The judge in this case, however, decided in that application important principles were raised and therefore the court found that it was in the interests of justice that those issued call for immediate resolution and decided not to remove the matter from the role for the litigants to decide on whether to mediate or note. So, while in this matter the judge was prepared to excuse the non-compliance with rule 41A, the court does make it clear that future courts might start taking the view that parties who do not file a rule 41A notice should not be heard.

Conclusion This, therefore, must stand as a warning not to simply refuse to mediate as such a stance could be met with a court refusing to hear the matter, or with a costs order despite overall success. Mediation should be considered even if it does not settle the whole dispute but can curtail the legal proceedings by settling some elements or issues which make up the total dispute.

• Coetzer v. Wesbank T/A Firstrand Bank Ltd 2022 (2) SA 178 (GJ) Here, the court made a costs order against a party in an interlocutory3 application. This is fairly unusual. Normally the costs of interlocutory applications will be considered and dealt with at the end of the entire trial. But in this case the court was influenced in its decision by the fact that the parties did not attempt to settle the specific issue in dispute themselves or by means of mediation as provided for in the rule.

CONSTRUCTION HEALTH & SAFETY

From crisis

to success Rhys Evans, Managing Director at Alco-Safe (www.alcosafe.co.za) shares some positive news about the welfare of workers regarding construction health and safety considerations. Rhys Evans

Alco-Safe Alcohol and substance abuse is not the type of problem that waits until after working hours. It’s a growing crisis with significant implications in the workplace for productivity, safety and employee well-being, particularly while people are on the clock. Many organisations have stepped up company policies, putting in place increased testing and reporting protocols to prevent, detect and manage substance abuse among their workforces. When undertaken with a proactive and preventative approach, rather than a punitive one, there is a clear correlation between the increased adoption of testing and reporting protocols, a decline in positive results, and a decrease in alcohol and substance abuse within the workplace. The result is a favourable transformation of workplace culture, fostering a healthier, safer and more productive environment while reducing alcohol and substance abuse.

A policy-based approach to crisis control A critical step in addressing intoxicating substances in the workplace is the implementation of a written policy that clearly states the company's stance on alcohol and drug abuse and details the consequences of contravention while outlining the measures that will be taken to test and enforce the policy. In addition to investigative and disciplinary measures, companies also have a duty to educate their workforce on the dangers of substance abuse, and to offer the appropriate levels of support for employees who find themselves with a problem.

Enforcing safety: testing for alcohol and substances In industries where intoxication poses a significant risk, regular testing using 74

summer 2023 | www.tobuild.co.za

breathalysers for alcohol, or saliva testing for chemical substances, is imperative. For logistical and cost reasons, compulsory alcohol testing of each employee at regular intervals throughout the day is more feasible than compulsory drug testing. As such, the organisation has to test for drugs according to their needs, and consistency is key to achieving the deterrent effect.

Compulsory versus random testing: unexpected results One company examined the impact of different testing approaches for alcohol testing across their two operational sites.

However, the element of surprise in random testing created a sense of uncertainty among employees and while this led to a higher number of positive tests, this was not the desired outcome. The goal is always to minimise positive results, as this shows that the prevalence of alcohol and substance abuse is declining.

Prevention, intervention and support In the ongoing battle against alcohol and substance abuse in the workplace, technology and increased testing play instrumental roles.

One site enforced compulsory testing for all employees, while the other conducted random tests. Interestingly, the site with random testing had a higher rate of positive test results despite conducting only a fraction of the tests compared to the compulsory testing site.

By leveraging innovative solutions and a consistent approach to testing, organisations can witness a remarkable decline in such issues. The commitment to addressing alcohol and drug-related problems demonstrates a strong dedication to employee well-being, workplace safety, and business success.

This can be linked to the powerful deterrent effect of compulsory testing. Individuals at the compulsory testing site were aware that they would be tested every day, significantly reducing the likelihood of engaging in risky behaviour.

With the right policies, procedures and technological measures in place, organisations can foster a culture that supports prevention, intervention, and support, ensuring the measurable well-being and productivity of their workforce.

Technology drives intelligent intervention Here, technology can prove to be of remarkable assistance in addressing substance abuse in the workplace. The integration of cloud technology, biometrics, and analytics capabilities that were previously not possible with testing procedures and results, such as: 1. Cloud-based cooperation: A cloud-based platform that enables real-time, secure data sharing is used to report, store, and make results accessible. This seamless exchange ensures that nothing falls through the cracks, even among operational sites that are spread out geographically. 2. Biometric identity authentication: Swift and secure identification of individuals undergoing testing with fingerprint or facial recognition saves time and ensures accurate results. Reporting plays a vital role in ensuring compliance and reducing manipulation of the testing process.

CONSTRUCTION OPINION

Contractors urge

dialogue on contracts Hot on the heels of the spotlight we put on the “construction mafia” in our September edition, the beleaguered construction industry faces many more challenges, one of them contract changes. MBA North Construction industry contract changes and conditions that slash margins are increasing risk to contractors and contributing to the downward spiral of the construction sector, writes Mohau Mphomela, Executive Director at Master Builders Association North (MBA North). The association’s members say urgent changes must be made to help the construction sector survive. The battling construction sector saw at least 88 liquidations last year and a decline of over 7 000 jobs in the past year alone, continuing the trend of the preceding five years, as reported in the media.

Contractors cite key issues MBA North member Wimpie Kies, Construction Manager of Belo & Kies Construction, says contractors face growing cash flow challenges and untenable contractual conditions, with margins slashed to around 1% to 2%, significantly lower than they were in the past. He points to unfair business practices such as contract amendments and withholding payment, as well as to slow and costly legal practices that force contractors to accept the situation and ‘take it on the chin’. “For some years, clients have started to push more and more risk onto the contractors. They string them along for months for payment and are continually finding ways to get what they see as more bang for their buck. But in reality, what they are doing is pushing risk and burden onto the contractors at no additional cost to themselves,” says Kies. Developers have also seen a shrinking market and rising interest rates, with far 76

summer 2023 | www.tobuild.co.za

fewer viable projects. To counter this, they attempt to “unbalance the contractual risk”. “Contractors have started accepting these risks to keep their workforce going in the hope that there will be an upturn on the next tender. But this hardly ever happens and so the spiral continues. Combined with this, the client wants the contractors to sign a waiver of lien and give an on-demand guarantee, but in most cases they refuse to give the contractor a payment guarantee. The clients also push more and more for unlimited product warranties.”

Ultimately, clients who continually ‘bully and manipulate’ contractors will find that contractors start declining tender opportunities and hiking prices and this is unsustainable. This means that more contractors will go into liquidation, resulting in project delays and increased costs as the competitive landscape shrinks. Quality issues will also start arising as the gap grows between experienced and new skills, he opines. “The experience and knowledge base in the industry is being eroded,” he says. “When a

OPINION

company closes, its employees may change industries altogether, or move abroad for work. We see a lot of people leaving for regions like Australia, New Zealand and the Middle East, where there is strong demand for South Africans due to their work ethic and experience. “In the current model, the main contractor has to beg clients for money to help subcontractors who have cash flow issues. Following the impact of Covid, we now see suppliers, contractors, and main contractors all grappling with cash flow issues, which can slow down work.

The JBCC contract was deemed a fair contract for all from the client to the contractor.

“Traditionally, the first reaction a professional team would have is to hold back more money, but this only serves to further slow the project and make the problem bigger, and it puts contractors at risk of liquidation”, he concludes. Gavin Morrow, CEO of W30, comments: “Since the collapse of Group 5 in 2019, the construction industry has seen a steady flow of very good main contractors go into business rescue or liquidation. The pace has increased significantly in the last couple of years with the latest casualty being Gothic Construction, a top-notch contractor. “The JBCC contract was deemed a fair contract for all from the client to the contractor. However, the last time we signed an unedited JBCC contract that was unedited to suit the clients’ interests was five to six years ago. What is often forced on contractors is to sign a waiver of lien, or issue a construction guarantee for performance. If one doesn’t agree to the conditions, the project goes to the next contractor who would happily accept these terms.”

CONSTRUCTION

“What is not often unmentioned when a contractor goes under is the knock on to all the smaller subcontractors who ultimately carry the biggest hit, who now join the begging bowl brigade behind the banks, guarantor providers, SARS and the business rescue practitioners for their cents on the rand,” Morrow opines. Christian Micha, Managing Director at Archstone Construction, adds: “Altering building contracts that were carefully and thoroughly implemented to protect and accommodate all, is the reason the construction sector is being taken apart block by block and the risk for the main contractor has become unpreventable. “Standard practice like Open Tenders have become a thing of the past and have been replaced by Closed Tenders. Also, a trend in recent years is that a large percentage of tender results are not being communicated, making it difficult for main building contractors to assume their merit in the market and post tender negotiations is also becoming the norm.”

Back to a tried and tested formula Kies says: “I am concerned that if the industry does not take a very hard look at itself and address the issues, this spiral will continue to the detriment of all stakeholders.” Other members agree: “Conversations must be held across the industry spectrum, with employers and consultants, because the status quo is unsustainable.” They call for contractors, sub-contractors and suppliers to stand together to get the industry back to where it once was – with no altering of the JBCC contract, as this method is tried and tested, and worked for all in the past. The industry must stand together and say enough is enough, in the opinion of Morrow. “From the clients, professional teams, industry associations and contractors, we need to ensure the playing field is fair, the margins are fair, and the contractor is treated more fairly. If we don't, this

industry will collapse, the suppliers linked to the industry will fold and all the secondary markets will be impacted hugely due to the large numbers involved.” He says JBCC contracts are altered as a means of passing down the risk – but this is not the answer. Companies need to assume the risk they signed up for.

“They hesitate to take a stand, fearing exclusion from future opportunities. As an industry association we stand together with our members to advocate for the strict observance of ethical standards, which ultimately benefits all involved. We urge all stakeholders in the construction industry to stand with us.”

“As the MBA North, we still have a voice to other governing boards in our sector to revert back to the basic recipe that has been proven to work in the past, in an attempt to save the industry. We had it right before with good business practice. I have no doubt that the construction sector still has a bright future in our country if the right solutions are found and implemented.” Mohau Mphomela, Executive Director at Master Builders Association North adds: “Due to the challenging nature of the business environment, contractors and sub-contractors frequently feel compelled to tolerate unethical business practices, only to later face repercussions.

CHEMICALS

Spalling sorted in warehouse refurb

Concrete spalling is a phenomenon in which the surface of concrete deteriorates and breaks off in small or large pieces due to various factors. This case study by Sika, demonstrates how the issue of concrete spalling in a warehouse was addressed using specialised construction chemicals. Sika The OVK Group, a leading agricultural company headquartered in Ladybrand, South Africa, has showcased its commitment to progress by completing a significant warehouse refurbishment project in Gqebera. The project, executed by a collaborative team of experts, marks OVK's continuous efforts to expand and enhance its services for all stakeholders. Addressing an imperative concern, the OVK warehouse rejuvenation project tackled the challenge of moisture ingress affecting the structural columns. The issue of serious spalling demanded swift intervention, which was expertly provided by Altrama, the engineering team responsible for the project. Geotech SA, the main contractor, lent their expertise to ensure the project's seamless execution.

The process The warehouse refurbishment involved a meticulous process. Initially, mechanical breakers were employed to remove damaged concrete, followed by comprehensive surface preparation to eradicate corrosion from the steel components. A key solution in the restoration was the application of Sika MonoTop®-1010 ZA a bonding primer and reinforcement corrosion protection cement-based slurry containing corrosion inhibitors with reduced carbon footprint. The MonoTop®-1010 ZA was used as an anti-corrosion agent on the steel surfaces. This product showcased its effectiveness in preventing corrosion and enhancing the structural integrity of the columns. The Sika MonoTop®-1010 ZA was brush applied through two coats and allowed to dry overnight.

To address the spalling, Sika MonoTop®412NFG was trowel-applied onto the concrete surfaces after the third application of wet Sika Monotop®-1010 ZA acting as a bonding agent, effectively executing the patch repairs. The Sika MonoTop®-412 NFG is an R4 repair mortar with a corrosion inhibitor ideal for this purpose. The comprehensive protection solution also encompassed the application of Sika® FerroGard®-903 Plus, an active corrosion inhibitor for reinforced concrete, which was sprayed onto the entire column surface. This step extends the lifespan of the concrete while bolstering its durability. In addition, a layer of SikaTop® Seal-107 ZA, a liquid applied cementitious waterproofing slurry, was added to the steel components, augmenting the effective cover to the reinforcing elements. This comprehensive approach not only fortifies the structural elements but also exemplifies the client’s dedication to quality and longevity.

Saving time and resources The success of this refurbishment endeavour highlights OVK's prudent decision-making. Opting for a refurbishment solution not only saved considerable time and resources compared to a complete rebuild, but also minimized operational disruptions. This achievement is a testament to the meticulous planning and exceptional workmanship exhibited by Geotech SA, coupled with the seamless workability of Sika products. 78

‘Young Engineer of the Year’ One of the youngest technical directors and shareholders at leading consulting engineering and infrastructure advisory firm Zutari, (www.zutari.com) Mareli Botha, was named Young Engineer of the Year at the CESA Aon Engineering Excellence Awards held in August 2023. Zutari Now in its 51st year and hosted in partnership with platinum title sponsor Aon South Africa, the awards celebrate innovation, quality, outstanding workmanship and professionalism.

“The combination of engineering, creative design, and the concept of making a difference to one of the largest problems internationally, namely the waste crisis and environmental impact, became my inspiration.”

Botha explains that she decided to study chemical engineering due to its connection to systems thinking. She then did vacation work in the plasma engineering department at the South African Nuclear Energy Corporation (NECSA).

This was followed by an internship under Professor Christophe Laux at the Laboratoire EM2C at CentraleSupélec in Paris. Botha was then invited to complete an international Master’s Degree in Project Management, Energy and Environmental Engineering. It opened her eyes to all the other options in environmental engineering and sustainable design. She is currently working in green process engineering and project management at Zutari.

Completing a couple of designs for a plasma waste-to-energy project, Botha says she discovered her passion.

Freedom to conceptualise new designs Botha explains that process engineering is usually the first discipline to start an integrated engineering design in the industrial space. “It is a lot of fun because it typically allows for freedom to conceptualise new designs,” she adds.

projects that could fundamentally change South Africa’s green economy, such as green hydrogen, biogas to energy, and waste to value. “These types of projects enable us to create new businesses, with the potential to generate numerous jobs, while improving the country’s sustainability profile.”

It also typically feeds into the business concept throughout the engineering phases, especially during early project phases.

Botha comments that there has been a significant increase in women in the process engineering field over the last couple of years, indicating that the industry and people’s mindsets are changing.

It means that job creation, operating philosophies, and environmental impact are a basic function of all Zutari’s designs.

“I believe a number of other engineering fields are seeing a similar change. Having good female role models in this field is important,” she stresses.

“For green process engineering, it is even more true, since sustainability concepts are embedded into the basis of every design,” highlights Botha.

“As consulting engineers, we work in a constantly changing industry. New technologies, new legislation, new risks and priorities for clients drive the types of projects the market needs,” says Botha.

Within this space, she works on fascinating 80

Ongoing self-development and adaptability to industry advances This calls for ongoing selfdevelopment and adaptability to industry advances. Lifelong learning is a reality in a field that calls for deep expertise and relevant skills. “It is both a challenge and a great opportunity. In my case I ensure that I interact with other experts daily to keep learning and adapting. I have never stopped studying and am currently busy with a PhD, which presents a different and fascinating learning experience,” says Botha. “Obviously, since the industry is so fast-moving, work-life balance can also become a typical challenge for most engineers. This is something to manage actively,” she adds. Botha is passionate about mentoring and says Zutari has provided access to excellent colleagues and mentors in her chosen field. “Having a mentor is very important and having the right mentor is vital. Young engineers should actively manage their own mentoring opportunities: Find a mentor, secure their buy-in, set up sessions, and follow up. You would not believe how willing people are to spend time nurturing the next generation of engineers,” she adds.

GEOTEXTILES ENGINEERING

Global research shows that rising temperatures, caused by climate change, are altering our normal weather patterns, affecting coastlines, homes and infrastructure, as well as animals and plants, all over the world. Global warming is increasing the frequency and intensity of storms, leading to disastrous flooding, which is intensified by rising sea levels. The effects of climate change on our environment will depend on how well we can adapt to ever-changing weather patterns and how much we can do to reduce global warming. “We need to boost initiatives to protect our natural environment and keep coastal areas safe and attractive for everyone to enjoy for many years to come. The installation of well-engineered and durable coastal protection structures has never been more critical,” says Sefton Fripp, Managing Director, Fibertex SA, specialists in the manufacture and support of nonwovens and performance-based materials. “In addition to coastal rehabilitation, authorities need to look at ways to preserve the integrity of concrete structures that are affected by salt water, high temperatures and increased CO2 levels and consider eco-friendly solutions that gently prevent soil erosion. “South Africa needs to do all we can to prevent damage on our shorelines, to reinforce rivers and stop devastating flooding of “The Fibertex team, populated areas,” he adds. with decades of experience in coastal protection, works closely with authorities around the world designing advanced ecological solutions to protect shoreline areas and save buildings Coastal and infrastructure.”

protection

Aging seaside infrastructure, large waves and narrowing beach widths, all contribute to the urgent need for coastal rehabilitation, to ensure greater environmental protection. Sustainable Fibertex products have been developed to withstand the effects of harsh wave action and are the perfect protection solution that allows beaches to retain their natural beauty. The company manufactures FiberRock® Geosynthetic Sand Containers (GSCs) which are used in the construction of efficient protection structures for coastal protection, erosion control, dune revetments and slope

stabilisation, as well as for emergency protection in floods. According to Fibertex specialists, using large sandbags as structural components of revetments is not a new trend in environmental protection, but the global Fibertex operation has made a substantial investment to design and manufacture the robust but soft FiberRock GSC system, as an alternative to conventional rigid revetment structures. The function of the lightweight and workable GSC system is to allow the free passage of water through the porous structure of the fabric and into the sand it carries, to absorb wave energy, while retaining the sand fill in the bag. This is unlike hard concrete structures, which predominantly protect by means of wave energy reflection, which would most likely have a negative long-term impact on adjacent structures. FiberRock GSCs consist of a strong porous base fabric, which is mechanically needlepunched together with a coarse antiabrasion and vandal resistant (AVL) cover layer. This durable fabric combination offers a flexible structure designed to retain a coarse fill medium, like sand, while allowing the free passage of water. FiberRock geotextile sand containers, which are manufactured from highly UV stabilised virgin polypropylene (PP) fibres, can withstand the effects of repeated wave attacks in harsh coastal environments and are the perfect soft solution to beach rehabilitation and coastal protection. Fibertex has given particular attention to critical factors in the development of this system, including abrasion, perforation, puncture and UV resistance, as well as tensile strength, elongation, permeability and drainage. GSC material selection is critical to the long-term stability of the entire structure. In the case of coastal protection applications, where high energy bi-directional flow conditions are encountered, needlepunched staple fibre (SF) geotextiles are preferred. They have proven to be durable and the staple fibre geotextiles do not delaminate under the harsh flow conditions expected from wave action. www.tobuild.co.za | summer 2023

ENGINEERING GEOTEXTILES

Polymer fibre selection Fibertex has selected virgin PP fibre, with excellent frictional and low density characteristics, as the basis for manufacturing its GSC fabrics. PP has a better performanceto-weight ratio than other more dense polymers, such as polyester. Although polyester is a strong, durable polymer, PP is preferred globally in the manufacture of heavy grade and voluminous GSC fabrics. Other important properties for appropriate product selection include the design of the revetment structure, where environmental influences such as wave velocity, wave amplitude, wave period and wave direction need to be considered. Size selection of GSCs for each application is also critical. Smaller GSCs might be sufficient for less harsh conditions, but direct wave attacks often require larger, more stable FiberRock GSCs. The correct installation procedure and optimal filling and closure of GSCs prevent free movement of the bag, to ensure the long-term stability of the structure. Fibertex GSCs, which are available in sizes between 200kg and 4 000kg, can be used in riverine, lagoon and coastal protection works, depending on specific environmental and engineering requirements of the designed structure. “We are currently working on a project in Umdloti, KwaZulu-Natal, to repair recent damage to the beach front embankment, which was damaged by tidal waves and heavy rainfall,” Fripp shares. 84

summer 2023 | www.tobuild.co.za

Most of the embankment had eroded during the storm, leaving the main road above the bank vulnerable to collapse. The scope of the project is to rehabilitate the area and prevent tidal waves from creating further damage. The company’s proposed solution was to install FiberRock GSCs that will provide permanent retaining support to the embankment and barrier protection against tidal waves. In addition, this structure would create a cofferdam to prevent waves from causing further damage and protect the working area.

Fripp says Fibertex has supplied GSCs for many local projects, as well as large-scale revetment structures in Africa, the Indian Ocean Islands, as well as in Europe and Australasia. “The Fibertex geosynthetics range encompasses nonwoven and woven geotextiles, gabions and mattresses, drainage pipes and fittings and erosion control and cellular confinement solutions. The company also supplies soil reinforcing products, including geogrids and geocells, as well as geosynthetic clay liners as part of composite lining systems in modern landfills,” adds Fripp.

LIVING SUSTAINABLY COMPOSTING

Composting - and your sustainable life In this two-part series, soil expert and scientist, Wesley Soule of Soil Scopes (www.soilscopes.co.za) shares the fundamentals of composting, why it is important, what benefits it offers and how it should be done. Wesley Soule

Composting is an activity that can be el, or practised at micro lev and nts me op vel de e on larg le cites Sou e. ltur icu agr in o als g in examples of compostin pe Ca the m fro practice Town area, where he works from.

Why compost? Composting our organic waste is a solution that addresses a huge variety of urban challenges currently faced worldwide, and we in South Africa are no exception. As landfills grow, pollution levels rise and the realities of human impact on the environment become more evident, we need to look more seriously at how we manage our waste. While composting is an age-old practice, it has received very little attention in modern urban planning, but all that is about to change.

summer 2023 | www.tobuild.co.za

COMPOSTING

LIVING SUSTAINABLY

What problems does compost solve? Waste management One of the foremost reasons to implement composting solutions in urban areas is its significant impact on waste management.

In urban areas, organic waste accounts for a substantial percentage of the overall waste. In a 2016 GreenCape market intelligence report, the City of Cape Town produced 7.7 million tons of waste, of which 2.9 million tons was organic waste. Diverting this material from landfills reduces the pressure on our already overburdened landfills which are set to refuse organic waste by 2027. When organic waste rots in landfills, it produces large volumes of methane, a potent greenhouse gas. Composting organic waste, on the other hand, does not produce these gases but rather stores those nutrients within the soil. Food security Urban composting systems can play a vital role in building food security. What was considered waste, now produces a high-quality composted material which is used to enrich the soil in urban gardens and allotments.

This supports local food production, reduces dependence on long-distance food supply chains, and improves access to fresh, locallygrown produce. Having this circular wasteto-food cycle means there is an incentive for people to value their waste not as trash but as something which helps them to grow food for themselves and their communities. Green business ecosystems Composting can foster a thriving ecosystem of green businesses. Compost produced from organic waste is a valuable resource for urban agriculture, landscaping, and horticultural enterprises.

There are also waste collection opportunities to assist companies with diverting this waste away from landfills into composting systems. This is an economic opportunity for the city to partner with small businesses to tackle

the enormous volume of waste. The famous saying that, ‘one person's waste is another person's treasure’ rings true here. Reducing cities' air pollution Good refuse collection is key to keeping the city clean but heavy garbage trucks have to transport these loads far from their collection point to the limited landfill options.

But the transportation costs are a heavy burden for the city and CO2 emissions from this contribute negatively to the urban air quality. Furthermore, organic waste that ends up in landfills decomposes anaerobically (low oxygen) which releases high quantities of the potent greenhouse gas, methane. By reimagining our organic waste streams, decentralised composting systems become a viable solution. Smaller scale, local composting sites which can handle organic waste within their immediate vicinity such as business parks, neighbourhoods, housing estates, etc. Composting organic waste correctly means we do so aerobically (oxygen-rich) which limits the release of any greenhouse gases. This means waste does not require long-distance hauling and causes limited greenhouse emissions from its decomposition which reduces the city's overall pollution. Addressing landfill issues Within the City of Cape Town, there are two operational landfills which are both severely under strain from the increased volume that the city has been producing.

The lifespan of these landfills has come under scrutiny as the air space limits imposed are expected to be reached by 2032, and the city is looking at various ways to extend this. Decentralised composting sites of organic waste can divert large volumes of material away from landfills allowing their lifespan to be extended.

LIVING SUSTAINABLY COMPOSTING

Urban composting done the right way Composting in urban areas can be very unappealing to people who often associate negative associations with compost sites such as foul odours, flies or vermin. While this is a concern, composting done the right way eliminates this potential issue.

Odour One of the main concerns people associate with composting is the unpleasant odours which can be created when anaerobic conditions occur. However, proper aerobic composting leads to far less odour because of the types of microorganisms which function in aerobic conditions. As previously mentioned, methane is produced by anaerobic decomposition in landfills, which creates a foul odour. As limited off-gassing is produced by aerobic conditions we do not have the bad smells. Proper management of aeration and moisture is key to keeping compost piles odour-free.

Flies and rodents Collecting organic waste is one way to attract pests who see the material as food. The simple solution is to quickly turn the organic waste into something the pests do not view as food. The solution is microorganisms which we use to rapidly consume the organic waste which creates significant heat. Temperatures above 65 degrees Celsius are expected within two to three days of waste arrival by using specific inoculations of microorganisms. This level of heat is excessive for flies and rats are deterred from the waste due to it. Within the first week of composting the organic waste does not represent food sources for these pests.

Small scale, wide reach Micro composting sites can be created across the city to manage local businesses and residential organic waste. These microsites feed compost back into their locations for gardens or natural spaces which is a closed-loop system that benefits the community. The separation of the organic material from the waste is done by the residents or businesses, it is diverted to the composting site team where the waste is aerobically composted.

Managing an urban composting site requires care to avoid pests and smells but is achievable with the correct practices.

In the next edition, we will look at some of the benefits of composting, especially on a larger scale with helpful advice for property owners, developers and also municipalities. Correct composting practices and management of these sites is something that my business works and consults on.

Is it possible to have seven power tools in just two devices? A distributor of premier tools shares some tips with readers of TO BUILD. Brandroid

Solving many puzzles: The jigsaw A jigsaw uses a reciprocating blade to cut irregular curves, such as stenciled designs, in wood, metal, or other materials. The tool's ability to carve out irregular shapes lends its name to the jigsaw puzzle, whereby each tile is shaped to connect to its neighbors Using a short flat blade, the tooth design of that blade is important for the application and performance of the saw. The tooth spacing, tooth shape, and cutting angle are important in providing speed, cleanliness of cuts, and optimal performance. The jigsaw is the most popular saw sold in the world. At the same time, a reciprocating saw is most loved by trade professionals. So why not combine the two into one? Premier tool supplier, Worx (www.worxSA. co.za), says it has taken these two saws to a new level by combining them together into one unique tool that is compact, powerful, lightweight, and cordless. The result? The Axis (saw) package presents itself as the perfect tool for a variety of indoor and outdoor applications, with its two saws in one feature. Getting more done faster is key for all home DIYers. 90

summer 2023 | www.tobuild.co.za

A reciprocating saw is a type of machinepowered saw in which the cutting action is achieved through a push-and-pull motion of the blade. Use this for demolition work, among other things, where blunt force tools cannot remove materials around doors and windows, and cut beams and drywall. Designed to work efficiently in tight spaces, the Worx Axis saw accepts all standard jigsaw and reciprocating blades via a tool-less clamp. It also includes a dust blower function that removes debris and dust allowing greater visibility whilst cutting.

Features include: • Tool-free blade change system for added convenience. • Variable speed for controlled cutting on various materials. • 4 Pendulum settings for improved cutting efficiency. • Dust blower for better visibility. • Rubber over-mould comfortable grip. • Lock-on switch provides enhanced user safety. • LED light provides better sight for dark areas. • Comes with five blades for wood, aluminum, timber, and steel. • Has one removable base plate.

The orbital sander Orbital sanders are hand-held tools that work by rotating elliptically to create a smooth surface. You can even use them to remove rust or paint. If you need a smooth surface in a short time, an orbital sander might be your best bet. A good example is the cordless 5-in-1 SandeckWRX WX820.9 Multi Sander, by

Worx. Used for its 5-in-1 capabilities as a finishing sander, orbital sander, detail sander, finger sander, and curved area sander, this tool offers a cordless multihead replaceable capability that does it all, saving users a fortune.

Try the Multi Sander and see how versatile and powerful it is, yet lightweight; a DIY tool for all sanding applications.

This model was designed with variable speed, allowing the user to control the rate of sanding. The dust stop microfilter box ensures low levels of dust while sanding and in turn creates a cleaner working environment.

Features include: • Voltage 20V • No-load speed: 4000-10000/min • Orbit action: Rotary - 2.5mm”, Detail- 1.8mm • Machine weight: 1.27kg

Using an orbital sander It's important to get a good uniform sanding over the entire workpiece. For example, when you're using a standard orbital sander you can start on the left and move progressively across, or vice-versa. Don't push down, even the slightest bit. The weight of the tool and your hand is enough to get the results you want. In fact, pressing down can bog the motor, slowing down the process and harming the surface. Let the sandpaper do the work. Also found in many DIYer workshops is the random orbital sander. Useful in finishing woodworking pieces, it can also be used for stripping paint and stains. Random orbital sanders were developed as an improvement over standard orbital sanders. The difference between them is that instead of simply rotating in a circle (which tends to create swirl marks on the material), the sanding disc on a random orbital sander moves in a circle AND in an oval orbit around the sander's Z-axis. This reduces the chance of creating distinct sanding patterns in the material.

Powering up The manufacturer says its two units are part of the exchangeable shared battery range, which allows you to interchange your 20V batteries with any of the supplier’s 20V tools across the garden and power tool ranges, allowing you to expand your cordless tool collection by sharing batteries and saving money. This is a unique cordless tool platform that uses the same battery to power 20V, 40V and 60V tools. Neat, heh? www.tobuild.co.za | summer 2023

LIVING SUSTAINABLY BIOGAS

Biogas cooks up a storm 360

Food scraps are an unlikely ally in any battle – except in the one we cannot afford to lose. Two military bases in Limpopo are proving that the war to save the planet can be won one kitchen at a time, says the South African National Energy Development Institute (SANEDI). (www.sanedi.org.za) SANEDI

SANEDI

A man on a military base who has specialised in the essence of a high-tech compost heap is not common – unless you find yourself on the outskirts of Louis Trichardt in Limpopo. There, on South Africa’s most northern air force base, civilian military member Morris Rathumbu has become an expert with a biodigester. Air Force Base Makhado and the 523 Squadron (SQN) army base in Louis Trichardt, were selected as the pilot sites for the Department of Defence’s biodigester project, in partnership with SANEDI. In 2021, this saw the installation of a pre-cast biodigester on each base to turn kitchen food waste usually sent to landfill, into biogas and used as energy for cooking.

“Biodigesters are the most labour-intensive renewable energy technology. I always say it’s like having a baby, and people don’t believe it until they have a biodigester to look after and keep alive.” Indeed, the biodigester must be kept alive, literally. Biodigesting is an organic and biological process driven by the same bacteria that keep the human digestive system healthy. These live organisms are the

reason that every biodigester is unique, with its own preferences and quirks. That is why they require such care. “I know that my biodigester uses more water on Wednesdays and in the time it takes me to sing Happy Birthday twice, I get enough water into the digester’s daily diet,” says Rathumbu. “I love this technology because it is like having a family. Learning about it has broadened my horizons.”

The biogas plants consist of large, sealed anaerobic digesters in which waste material is decomposed to produce methane gas. These were installed underground at the bases to make them unobtrusive and to prevent any unpleasant sights or smells. In addition to gas for cooking, the digesters produce an organic by-product, called the digestate, an excellent fertilizer.

Solution to the twin problems of waste management and energy costs This relatively simple solution to the twin problems of waste management and energy costs makes perfect sense. However, a critical success factor that often scuppers biogas projects is the people factor, says Sanedi’s Dr Karen Surridge. 92

BIOGAS

A resounding success story Surridge remembers introducing the project two years ago and Rathumbu immediately being interested. “It is thanks to his dedication that the project is such a resounding success at the air force base,” she says. Where it usually takes a biodigester six months to become fully operational, Rathumbu’s “baby” got there in only four months and in the two years since it has run without a single glitch. “I’ve never seen anything like this,” Surridge says. “It is unheard of for a biodigester to be this successful.”

Enough gas to cook two meals a day for 220 people The upshot of this is that it produces enough gas for the stove-top cooking required to provide breakfast and supper for 220 people every day, thus saving a predicted

Learning opportunities Fortunately, none of these incidents killed the initiative but they provided ample learning opportunities. Although it has taken almost 21 months to reach full capacity, 523s biodigester is humming these days, producing enough cooking gas to prepare daily meals for the people stationed at the base. Over the past two years, Surridge collected performance data from both biodigesters. To date, 17.5MWh of electricity has been saved, 6.5 tons of CO2 emissions avoided and 30 tons of kitchen waste diverted from landfill. The two bases were carefully chosen to demonstrate that biodigester plants can be tailored to specific needs and provide a wide range of solutions, and that they can be scaled up or down by orders of magnitude, depending on the energy requirements and raw materials available. “Two years down the line we can declare the pilot a success,” says Surridge.

ended up in the biodigester and instantly killed all the bacteria.

Based on this performance, it will be possible to add two more biodigesters in parallel on this system to power additional cooking burners and a water heater in the kitchen.

There was also the time when the system was fed too much undiluted starch, which clogged the pipes and the resultant gas build-up blew back into the kitchen through the sink. “It looked like the macerator had vomited,” adds Surridge.

The pilot at the army base followed a more roundabout route to success. Although the base commander had also adopted his biodigester from the start, his duties as a high-ranking officer limited the attention he could pay to it. Twice since July 2021 the biodigester has“died” and had to be resuscitated – both times when the commanding officer had been away from the base. Surridge laughs at the memory of receiving a phone call on a Saturday morning: “Doctor, the baby is dead!” lamented the officer. It seemed that cleaning fluids used to clean the sink in which the macerator is installed had

The technology requires a mindset of doing something for the greater good Reflecting on what the project team have learned and will apply in future projects, Surridge emphasises again the human-centric nature of the technology. It is a live system that needs looking after, and while it’s not a full-time job it is certainly a constant one. “This technology requires a mindset of doing something for the greater good,” she says. It's important to integrate the system into the daily routines and rhythms of a kitchen. The sink with the macerator that chops up the food scraps must be where the food preparation is done, and the gas burners close to the existing stoves and ovens. Finding ways to automate the system further is something that is currently being assessed. These will make adoption easier. The reality is that a biodigester is at first novelty, but it loses its shine, and then interest wanes in it. Also, it takes about six weeks of feeding the system before it starts producing any gas and another two or three months before it is suitable for cooking. “After much effort you will have almost zero return for several months. That’s a long time to keep the faith,” says Surridge.

The rewards are plentiful Once it works like it should, the rewards are plentiful. Not only are the bases saving money and supporting the environment and contributing sustainably towards the DoD’s green soldiering initiative, but during loadshedding, gas from the biodigester has supported the AFB Makhado kitchen in preparing hot meals. Furthermore, the more gas is used, the more the digester can produce. At present the gas is not storable and needs to be used as it is produced. The biogas project is one of several waste recycling and energy saving programmes being undertaken by the SANDF in partnership with SANEDI. The DoD and SANDF want to reduce energy-usage costs, while ensuring that military bases have energy security in a constrained energy system. The biogas project is also aligned with the SANDF’s green soldiering concept under which strong environmental protection measures are being introduced in all its operations. www.tobuild.co.za | summer 2023
