SA's greenest C

intocare Hospital in the green Menlyn Maine precinct is a tailor-made, high-performance clinical centre of excellence focused exclusively on head, neck, spinal and vascular surgery.

Africa’s first certified green hospital, Cintocare incorporates numerous sustainable design and management features, earning a 5 Green Star Custom Healthcare design certification from the Green Building Council South Africa (GBCSA). Healthcare facilities with green design have been found to deliver 15% faster recovery rates, a 22% reduction in need for pain medication, an 11% reduction in secondary infections, and an 8.5% reduction in hospital stays. Cintocare is also South Africa’s first hospital to generate its own oxygen on demand using an installed PSA (Pressure Swing Adsorption) plant.

The property comprises seven levels: three parking, one for the plant room, and three clinical and consulting levels. The development partnership delivered the full suite of services for the 100-bed hospital.

It incorporates 15 consulting rooms and five theatres, including one hybrid theatre, with the potential to increase this number to eight.

The initial architectural brief to A3 Architects envisioned the building as a symbol of mobility in the human body represented through presentday construction methods, while containing a mass of complex service networks required to supply the stateof-the-art equipment housed within.

With the site footprint fully utilised and enclosed on three sides, the design raised the hospital above the required parking areas. Green walls surround the parking from the ground up and float the hospital on ‘green lungs’. This allows clinical areas on upper levels to have access to natural lighting from north and south aspects.

Central to the architectural design is the visual link to nature from internal and street-facing areas of the hospital. The main reception and all clinical areas face two large atriums at the centre of the hospital, allowing visitors, patients and medical professionals to be welcomed within a space where nature is appreciated and aids in recovery.

The continuation of landscaping, designed by Bertha Wium Landscape Development, from the ground floor through to the Level 4 and Level 7 gardens plays a critical role in providing the majority of the wards and consulting areas with a view and access to nature.

The building’s exterior reflects its fundamental purpose. The swooping glass façade, which also serves to shade the building, represents a curve in the spinal vertebrae found in the neck, hinting at the inner purpose of the building.

Externally, the conceptual use of a single flowing strand creates a sense of unbroken movement in the design of the façade, linking a sense of mobility and proportion

#1 C int o c a re H o s pita l

with contrasting horizontal elements. The result is a building that stands out from the ordinary though reflection of its function.

The heart of the hospital lies in its east and west atria, with both sides providing visual links to nature. Natural lighting is introduced by means of multiple skylights, thus creating a comfortable and relaxing space. This link is reinforced through use of natural materials, textures and colours.

The Level 4 entrance and reception provide a free-flowing link between the atria, Menlyn Maine Shopping Centre, and a well-positioned coffee shop – all facing inwards towards lush planting, all the while maintaining a unique contemporary feel.

Nature in the space addresses the direct, physical and ephemeral presence of nature. This link between nature, the benefits of biophilic-orientated design and healing of the human body embody the ideology and the basis of the design.

Instead of walls, the building floats on green lungs and celebrates nature by incorporating landscaped areas across all levels and through use of beautiful organic forms and materials.

The hospital has earned South Africa’s first Custom Healthcare 5 Green Star rating from the Green Building Council of South Africa (GBCSA) – making it the first hospital to achieve this milestone.

The collaboration between Growthpoint, Cintocare, GBCSA and the professional team has resulted in a new green building certification tool for the healthcare and property sectors. This green certification tool is a roadmap to drive the development of more green healthcare buildings in South Africa in the future. The team has created a sustainable healthcare facility designed around the wellbeing of patients and hospital staff that supports the environment and its communities.

The new Cintocare Hospital leads the way in hospital design centred around the wellbeing of both patients and staff. The focus on the importance of green building elements has ensured that the hospital has embraced the healing component so often lacking in health facilities.

LANDSCAPING With limited area for landscaping, Bertha Wium Landscape Development, led by Walter Language, was tasked with maximising the effect of the green landscaping on sidewalk level. This was achieved using dense and fastgrowing evergreen trees, shrubs and groundcovers. A layering effect on the narrow sidewalk provides sufficient green to ground the impressive structure in the surrounding streetscapes and link in with the greater Menlyn Maine Precinct landscape philosophy. Green screens continue this layering effect on the façade of the building, which is a combination of live plants and artificial foliage.

Various pause spaces had to be created for patients, visitors, doctors and nurses in the form of outside courtyards. Weight and area limits necessitated the clever use of greening to soften these courtyards on the top floor of the hospital. Flowering and creeping plants were used in various pot sizes in conjunction with ambient pergola structures. Textural use of hard landscape elements supports the limited planting additions of each area to complete a cohesive entity. •

The addition of a shop and café to Bosjes Estate in the Breede River valley adds design and complexity to the visitor experience and the historical narrative of the region.

Phot og r aphy Dave Southwood

B

osjes Estate, in the scenic Breede River valley near Worcester in the Western Cape, has completed the next phase in its evolution, following the launch of the award-winning chapel in 2017 (featured in the April/May edition of Leading Architecture + Design that year).

The visually arresting design of the chapel, with its swooping, ethereal, winglike arches, helped establish Bosjes as a destination, precipitating something of a ‘Bilbao effect’ and effectively putting this part of the Western Cape on the map.

Bosjes successfully established itself as a popular destination for weddings and events, as well as for other visitors who wished to dine at the restaurant or stay over at the guesthouse.

Its success, however, necessitated further development and additional elements to extend the experience and accommodate day visitors with a more varied and comprehensive hospitality offering. Carlen Vorster, CEO of hospitality and marketing, explains that the estate

wished to provide additional facilities for incidental visitors – particularly on weekends when the restaurant and guesthouse are often booked for private functions – so that they can linger and explore the estate.

The new additions at Bosjes include a new pantry-style coffee shop and farm shop set in beautifully landscaped indigenous gardens. The Winkel is Bosjes’ contemporary interpretation of a country store, curated by interior designer Liam Mooney, while the Spens blends the best elements of a café, coffee shop and well-stocked country pantry.

The additions were conceptualised

by London-based, South African-born architect Coetzee Steyn of Steyn Studio, who also designed the chapel. He worked closely with Meyer & Associates Architects – who were appointed to assist Steyn as project architects and principal agent – and Square One Landscape Architects.

Intricate trellis structures emerge from the ovoid interiors of the submerged ‘pods’, formalising the landscape and providing a visual prompt towards the café/restaurant.

www.LeadingArchitecture.co.za JUNE/JULY 2021 17

Bl ue print

The conical timber structures tie the buildings back into the landscape, defining the space around them and bringing an intimate human scale to the outside seating areas.

Tiaan Meyer of Meyer & Associates Architects, who designed the nearby Botes Halte School (featured in December/ January 2019 edition of Leading Architecture + Design) explains that, while the chapel remains the most prominent architectural feature on the estate, and the manor house remains an anchor, the new additions are designed to function as “discoveries” that visitors would make while exploring a “magical garden”.

This approach allowed for the new buildings to explore a distinct brand of architectural intrigue while remaining deferential to the chapel and manor house. Rather than standing out, Meyer says that the Winkel and Spens have been conceptualised as “pods embedded in the landscape”.

He points out that the gardens have been designed in a “processional fashion”, leading from the parking area to the chapel and formalising the axis between the manor house and chapel. “There’s also a meandering path through the gardens as an alternative, where visitors ‘discover’ these two architectural events, the shop and the deli,” explains Meyer.

The buildings fuse with the landscape,

18 Leading Architecture + Design JUNE/JULY 2021

integrating the gardens and architecture “with gardens that wrap over new buildings, which in turn are woven back into the landscape with intricate trellis structures”, as the Steyn Studio’s official description puts it.

The way in which the architecture is buried or embedded into the landscape also helps to make the addition of a substantial banqueting kitchen and other services all but invisible.

“The two carefully burrowed buildings draw inspiration from the ways of the San, as well as the early Dutch settlers who first inhabited the valley,” explains Steyn.

The simple architectural forms of the buildings were inspired by the San huts called a ‘Matjieshuis’ (Mat House) as well as the first dwellings of the Dutch settlers, called ‘KapHuis’ (Truss House), which in turn are said to have been influenced by San building techniques and materials. “ The Matjieshuis was a portable, curved, slat-framed structure covered with woven mats, used by San herders as they migrated seasonally with their cattle during precolonial and early colonial times,” explains Steyn Studio’s rationale. “The KapHuis was a series of A-frame trusses covered with

#2 B O S JE S S P E N S A ND W INK E L

thatch, with the interior lowered to allow for more headroom. Both structures were part of this historic landscape and blended subtly with their surroundings.”

The curved oak trellises that emerge from the ovoid interiors of the submerged “pods”, formalising the landscape and providing a visual prompt towards the café/ restaurant and gift shop, are inspired by the lattice and weaving structures drawn from these historical precedents, albeit in a refined, abstracted interpretation.

Meyer points out the way in which they help anchor the buildings and define the space around them, bringing an intimate human scale to the outside seating areas while noting that they will eventually be covered with climbing plants, like large pergolas. More than a dozen species of climbing plants – from bougainvillea to honeysuckle, star jasmine and wisteria – will add seasonal colour, texture and aroma to these striking architectural creations.

He notes that these finely wrought conical timber structures were a feat of engineering and construction, necessitating close consultation with specialist engineers throughout, first Arup and later Henry Fagan once the subcontractor was appointed.

“The timber selection was very important, having to balance durability and strength, and still being pliable enough to be bent into shape,” he says. “It’s a structural unit that pulls together four layers bound together by stainless steel pins at the

intersection of all four.”

“We were brought in to specifically address complex geometry of the timber design intent, which involved doubly curving the timber laths.” says Tessa Brunette, associate at Arup.

The glazed façades were designed in a zig-zag formation so that they would not interrupt the pattern of the trellis as it extends between the interior and exterior.

Arup is an independent firm of designers, planners, engineers, architects, consultants and technical specialists, working across every aspect of today’s built environment.

We provided specialist timber and parametric structural engineering design for the curved timber lattice, façade engineering for the folded flush glazing, and thermal comfort advice alongside SANS XA reporting.

Top: The low profile and embedded character of the new interventions is subtly stitched back into the surrounding landscape, leaving the panoramic mountain views unobscured.

Above: Circular sandpits for children reference South Africa’s traditional farm dams and reservoirs.

Arup provided assistance, she explains, not only in understanding the qualities and capabilities of the timber itself, but also in the parametric modelling used for the structural analysis and feasibility studies.

“It’s quite complicated because the timber is not only curved in one direction, it’s actually doubly curved,” she says.

The parametric modelling, Brunette explains, was used to create a structural system that would meet Steyn’s design requirements within the constraints of the technical ability of the materials, fabrication rules like “how long and thick can a piece of the timber be to allow you to twist it”. These modelling techniques speed up the process and find practical design solutions. In the end, oak was selected for its combination of flexibility and durability.

20 Leading Architecture + Design JUNE/JULY 2021

“Kudos to the construction team for making it work,” she adds.

The glazed façades were specially designed so they would not interrupt the “wonderful shape” of the trellis, as Brunette puts it, and for the trellis pattern to appear continuous as it extends between the interior and exterior. The zig-zag arrangement of the glazing imitates the pattern of the trellis, and also makes possible the vertical structural spans of glass.

“We worked closely with Square One to not only position the built structures in the landscape as curiosities, but also as anchors around which the landscape was eventually designed. The seamless integration of the landscaping elements with the built structures was an essential design objective from the start of the project,” explains Steyn.

The landscaped gardens are spread across three sloping terraces, connected by a curving pathway that provides universal access while creating a visual link between the woodland landscape, forested play areas, spacious lawns and conservation garden planted with endangered renosterveld.

“The concept for the gardens was around incorporating ecology into the cultural landscape,” explains Mark Saint Põl, director of Square One Landscape Architects. “How do we tell the tale of cultural heritage, and the tradition of living off the land, and turn that into something accessible and enjoyable?”

Across the site there are visual cues that remind visitors of the cultural heritage of the valley. A series of water furrows

and channels speak to the ingenuity of farmers in taming this drought-prone wilderness. The fragrant citrus groves in front of the Winkel and Spens are a reminder of the region’s rich agricultural tradition. Circular sandpits for children reference South Africa’s traditional farm dams and reservoirs, while in the dedicated children’s play area, equipment includes kid-friendly farming implements, sandpits and splash-pads.

“Using stone from the farm in drypacked walls, and the narrative of farming implements to create play equipment, we wanted kids to engage with natural play using raw materials,” adds Saint Põl.

The woodland merges subtly into beds planted with a wide array of indigenous grasses, succulents and bulbs, each

carefully chosen to ensure a planting palette of seasonal interest that celebrates the colourful diversity of Cape flora.

Together, landscape and architecture effectively mediate the way in which visitors to Bosjes Estate appreciate and understand not just the architectural heritage of the estate, but also the broader social, historical and geographic context.

Team cohesion: the secret to success!

C

omplex projects, such as Bosjes Spens and Winkel, are successfully completed by teams and not individuals.

The contractor, employer and whole professional team must work together towards one goal.

In a team, no one is more important than anyone else.

Serving the common goal becomes the team’s main focus. Strong leadership keeps all team members focused on their individual tasks. We need to ask ourselves: “Am I a team player or do I only want to boost my own ambitions?”

Choose your team members wisely. The fact that a potential team member has previous experience of a specific task should not be the only requirement for the job. Character outweighs experience in tough situations. To be successful, you need gutsy members with character to persuade those with ‘experience’ that a job can be done, rather than simply to agree that it cannot.

David knew what he was capable of and did not listen to the negativity when he decided to face Goliath.

A balanced team has a far greater chance of success than one that is unbalanced. In the same way, a super-talented individual doesn’t make a winning soccer team, but teamwork does. All members of the team need to pull together.

Working as a team may also mean that fellow team members have to pick up the weakest link for all to succeed. Rather than leaning on someone else, we all should uplift each other.

Strong leadership, character and equal effort can only function well with proper communication. In this age of more connectivity and less connection, team members must go the extra mile to communicate efficiently. It is the responsibility of the communicator to ensure they communicate effectively. It is no use shouting at a teammate to pass the ball when he is too far away and can’t hear you.

Get closer so he can hear you, and he will pass the ball.

Teams that work well together, stay together and are more successful. It is important to keep winning teams intact.

Individual members learn to understand each other over time and you don't want to loose that cohesion that was built. Having that special “glue” that keeps a team together is key to success.

At 2iiConsulting, we focus on the project and work alongside fellow team members to one common goal. We are team players and are always passionately involved in all our projects. The size of a project does not matter when you put your heart into it.

Put us to the test. • www.2iiqs.com

Conceptually, Irene Link Building B has been designed as a permeable glass envelope that would allow for seamless views between the high-energy presence of the N1 highway and the quieter pedestrian scale of the adjoining Impala Precinct to the south.

uilding B, the second building in the developing Irene Link Precinct commercial office park in Centurion, is now complete.

Directly adjacent to the Barloworld Logistics building (featured in the October/November

2019 edition of Leading Architecture + Design) – which was the first building in the precinct to be completed – the four-storey modern glass, aluminium and concrete building has been designed

by Nsika Architecture & Design to have a distinct

visual identity to help it stand out from its neighbour. Nsika also designed the Barloworld Logistics building, which features striking distinctive organic curves that communicate the new vibrancy and economic growth of the precinct.

#3 IR E NE L INK BUIL D IN G B

The building's dynamic geometry, punctuated with projections, sits lightly on a naturally ventilated basement.

Building B adds 7 200m2 of lettable office space to the precinct.

“In keeping with the envisioned architectural language of the precinct, the design employs highperformance glazing, off-shutter concrete versus rendering and steel/ aluminium screening – contemporary materials that knit the building into its context while maintaining a unique architectural identity,” says Nsika director Bryan Charters.

Nsika’s architectural concept was to create a permeable glass envelope that would sit lightly on a naturally ventilated basement, allowing for seamless views between the high-energy presence of the N1 highway and the quieter pedestrian scale of the adjoining Impala Precinct to the south.

The main entrance is centrally located on the north-facing façade of the building, overlooking the N1 highway, accessed via landscaped steps from the parking area.

The northern façade, which faces the N1 highway, consists of two bold floating off-shutter concrete boxes flanking a triple-volume atrium.

This impressive central space creates a sense of arrival and provides a ‘wow factor’ for building users.

The front door, centrally located in a three-storey atrium, is accessed via landscaped steps from the parking area along the northern boundary. The stair and lift open into the atrium, thereby allowing all building users to engage with the atrium space.

A large, four-storey-high roof overhang creates an outdoor covered arrival space, as well as practical shading for the atrium. The fourth-floor aluminium louvres act as shading, as well as balustrading screening to the top-floor offices. Large areas of double glazing with opening sections every 3,6m allow abundant natural light and ventilation into the building’s internal spaces.

The southern façade engages with the precinct on a more intimate pedestrian scale. “We have pushed the basements

as deep as possible so as to maintain the ground floor relationship with the street,” says Charters.

“This allows pedestrians to engage visually with the building.”

The building massing and articulation follow the lines of the road, allowing for a dynamic geometry punctuated with projections. Extensive landscaping across the site softens the building, effectively integrating it with the urban park look and feel for the larger precinct. Planting along the podium softens the edges and introduces greenery to the spill-out areas.

The precinct is being developed with sustainability as its core aspirational value, and Building B has a 4-star Green star rating, thanks not only to cutting-edge technology, but also to passive design, including building orientation, limiting the glazing on the east and west façades, deep northern overhangs and shading. Irene Link aims to achieve a soughtafter 4-star certification from Green Star SA as a Sustainable Precinct. •

Urban art gallery Phot og r aphy Barry Gol d man

The intriguing design of Rustenburg Mall, designed by MDS Architecture, provides unique sensory experiences and an urban art gallery while celebrating the power of teamwork.

A

fter almost seven years of planning, Rustenburg Mall opened its doors on 29 April 2021. The development is a collaboration between Moolman Group, Twin City Development and JB Holdings.

Pierre Lahaye, partner at MDS Architecture, says, “The design of the 40 000m2 Rustenburg Mall is rooted in the context of its surroundings, both natural and developed. The renowned Rustenburg Kloof features dramatic rock formations and iconic Acacia trees. The broader area has several agricultural businesses, and the site is located within 1km of the largest public

transport hub in South Africa, which serves both taxi and bus commuters.”

The form of the building mimics a tree.

The tree symbol is so entrenched in the plan of the building that it also serves as the key design element in the logo for Rustenburg Mall, which is a clean and contemporary take on the revered Acacia tree.

There are over 120 stores in Rustenburg Mall, ranging from popular national tenants to new stores such as Drip, Home Choice, Legends Barber, Sneaker Factory, Offspring

by Uzzi, G-Star, Polo, Primark by Truworths, and Le Coq Sportif as a standalone store.

CLIENT BRIEF The public transport hub and broader road infrastructure was important to consider in the design, as was climate control, considering the high temperatures experienced in Rustenburg.

CONSTRUCTION CHALLENGES AND INFRASTRUCTURE INVESTMENT Construction commenced in October 2019 but the project faced delays due to the six-week COVID-19 lockdown during construction.

Despite these challenges, Rustenburg Mall opened within a month of its original opening target.

Pieter Lombaard, CEO at Moolman Group, says that the team worked tirelessly to make up construction time lost during the lockdown.

“The professionals rallied together to meticulously work out ways to complete the project on time, despite the halting of all construction works. Their

efforts have ensured that Rustenburg Mall is yet another exceptional retail solution with incredible customer experiences – all within the planned timeframes.”

New link roads connect the Rustenburg community with major arterial roads.

A covered pedestrian walkway – one of the largest in the country – creates a convenient connection from the city centre and transport hub.

It encourages commuters to explore the precinct and brings people into a world of retail.

Says Lahaye, “The arrival of shoppers on foot or via public transport provides an opportunity for developments like Rustenburg Mall to become meeting places that create new city squares with retail offerings.”

STRUCTURAL DESIGN AND EXTERIORS Rustenburg Mall has three entrances, which evoke

appealing tree-like canopies as if to invite gatherings. Each entrance also features large sculptural signs made up of individual 2m-high lettering structures to proudly emphasise Rustenburg.

Lahaye says the design of the roofs at Rustenburg Mall is inspired by Acacia trees and their symbolic representation as expansive

shelters for get-togethers.

The contextual rock formations and Acacia tree inspirations have translated into the structural design and aesthetics of Rustenburg Mall.

Careful attention has been given to bespoke features that celebrate creativity and mimic its natural surroundings.

Exterior tactile materials like timber and steel are softened by vertical gardens that blend into the very fabric of the building.

INTERIORS Internally, Rustenburg Mall’s design offsets timber and crisp white features for a contemporary, organic experience. The ceiling features strategically integrated lighting – custom designed lighting features ribbon-like elements to guide shoppers through the building while allowing them to acclimatise as they cross over the various sections of the shopping centre. In addition, feature mobiles

and abundant natural light create interest and ambience.

“The building celebrates artistic creativity while offering a wide selection of stores. Bulkheads are dark to integrate with the shopfronts in the shopping centre and serve to further highlight the artworks at the end of the mall. The developer contracted a curator to ensure diverse artistic representation, so we created galleries throughout the malls for unique graffiti and artwork installations by renowned South African artists. The artwork is placed high up in the distance, creating an interesting urban art element,” explains Lahaye.

The building features several subtle nuances and a sense of being inside the skeleton of the structure, which is emphasised by rib-like timber features overhead. “We liked the idea of showing the structure of the building in a neat and clean way,”

explains Lahaye.

The colour palette, along with the changing patterned floor design, includes references to sunsets, the sky, and forests at the promotional courts.

The tiling patterns are intricate and were inspired by woven baskets and rocks. To avoid cutting tiles, patterns were pixelated.

Angular shapes and distinctive stone-coloured flooring designs echo the renowned rock formations of the Rustenburg area. The ablution facilities feature warm timber and stones, while black tiles provide added texture. In the lounge area, patterned high-gloss metropole tiles provide a tactile and comfortable space to rest.

The design ensures that Rustenburg Mall is a familyfriendly space where shoppers can escape the searing heat in the area.

THE MARKETPLACE The Marketplace is a multi-functional, central

entertainment area and the perfect spot for socialising.

“Having its own entrance uniquely formalises activities for a rich, tactile and unified experience. The Marketplace design brings people together into a flexible gathering place that is dynamic yet celebrates creativity and bespoke offerings,” says Lahaye.

Clockwise from top left: The Marketplace, a central entertainment and socialising area, offers pop-up stores, a giant chess board, children’s play areas and communal dining area to serve the nearby restaurants and take-away eateries.

Several full-sized Acacia trees take pride of place in the vibrant area, creating a living tree canopy indoors.

A massive LED TV screen adds to the audio-visual entertainment offering.

The Marketplace offers pop-up stores, a giant chess board, two different children’s play areas and communal dining area to serve the nearby restaurants and takeaway eateries. Wi-Fi is available at Rustenburg Mall and a Wi-Fi-enabled area is incorporated in The Marketplace.

Flexibility in The Marketplace was achieved by incorporating kiosks and tuk-tuks, bringing together bespoke, craftlike offerings with more mainstream food offerings.

A service spine was created throughout The Marketplace for drainage, as well as for water and electrical connections.

The design includes ribs located every 5m to connect into this spine.

THE FUTURE OF RETAIL As leaders in retail architectural design, MDS Architecture is at the forefront of trends. Lahaye says that several emerging trends in retail design are showcased at Rustenburg Mall. Online shopping has increased with the emergence of COVID-19, so greater storage areas have been incorporated in the design for retailers. “Function and fun both have a role in the retail design of the future.

But making them work together requires flexibility – the more flexible the design is, the more easily you can adapt to what happens in the world. Outdoor lifestyle offerings are increasingly important to facilitate social interaction, and accessibility is key,” he says.

In addition to great shopping variety, easy access and a unique sensory experience, it seems shoppers at Rustenburg Mall are also getting glimpses of the future of retail. •

The ceiling features ribbon-like custom designed lighting features to guide shoppers through the building.

SA cement producers engaging for sustainability The cement industry in South Africa continues to engage government to create conditions that will sustain the sector’s local production capacity and grow market demand.

Speaking online at the Cemtech International Cement Conference, AfriSam marketing and sales executive Richard Tomes noted that the rise in cement imports and the application of the carbon tax were among the key issues under discussion. He said that the local industry was making steady progress in its climate mitigation journey, and that South Africa was among the leading countries in driving down the carbon footprint in the cement and concrete industry.

He highlighted that cement imports were on the increase again, having peaked in 2014 at about 1,2 million tons. Importers were generally from countries that did not have a carbon tax like that which was recently applied by the South African government to local producers. Neither did the importers contribute in terms of

Social and Labour Plan initiatives, as they did not conduct any mining activities locally, nor other projects related to the upliftment of local communities.

“When you have a situation where importers of cement are not subject to these added costs, it poses a threat to the viability of the local industry, and will ultimately have a negative implication for the levels of employment and social transformation,” he said.

These imbalances were exacerbating the stresses arising from the country’s longest ever business cycle contraction, which had seen infrastructure spending decline and had driven some large construction companies into business rescue. The COVID-19 pandemic had then accelerated this downward trajectory, leading to dire conditions in the large civils and building industries.

“It has become increasingly difficult to maintain profitability in an environment of surplus cement

capacity and declining infrastructure spending by government,” he said.

“The sector’s total installed capacity is currently about 20 million tons, with demand at only around 13 million tons.”

Despite the poor performance of the economy, Tomes noted that the South African cement sector was continuing to improve its climate mitigation performance in terms of carbon footprint. The local industry was a global leader in developing

blended cement technology, making use of waste products such as ground granulated blast furnace slag and pulverised fly ash to extend and enhance its cements.

“This has allowed companies like AfriSam, for example, to achieve average emission levels in its cement production of 574 g/kg – which is well below the global average of 890 g/kg,” he said. www.afrisam.com

Stylish and powerful gas fires

A decade or so ago, gas fires in South Africa were designed to operate with an open chimney to remove the fumes from the combustion process. They typically had glowing artificial coals or logs on top. Well set up, they looked remarkably like a real coal or log fire operating. However, the combustion process produced lots of dangerous fumes that needed to be vented up a chimney. Along with the fumes went about 70% of the heat from the fire.

These flued gas fires were popular in a time when petrol and

gas were a lot cheaper than today, even though they were limited in their heat output. With fuel prices increasing substantially, flued gas fires decreased rapidly in sales. The cost of warming a section of your home with one of these became prohibitive.

Fireplace designers looked at ways of burning gas with a good flame effect and with minimal emissions, to provide cost-effective and visually attractive heating.

Ten years ago, the Infiniti Fires Flame Dancer gas fire was launched on the South African market. With remarkably low emissions, they are very safe to use without a chimney. With no heat loss up a chimney, these grates are powerful heaters, capable of heating large volumes of a home.

With several different fireplace designs, these fires have become popular sellers, with all the benefits of large amounts of heat

Save electricity with Isover Glasswool Saint-Gobain believes in building and renovating homes in a way that results in greater levels of comfort, health and wellbeing, with the emphasis on environmental concerns when enhancing your own urban habitat. Households account for a significant portion of energy consumption – mostly to provide heating and cooling, but much of this energy is wasted due to inefficient systems and designs.

Aerolite is made from glasswool, which is made from a combination of naturally occurring silica sand, fluxing agents and up to 80% recycled glass. Glasswool has a Zero Ozone Depleting Potential (ODP) in both manufacture and composition, and Zero Global Warming Potential (GWP). Isover Glasswool is manufactured locally and tested according to the quality system at Isover South Africa.

In the production of each glasswool product, 95% of the raw material used are sourced locally, with 5% imported. Thanks to its impressive recovery qualities, Aerolite can be compressed to as little as one-tenth of its original thickness. This saves on storage and transportation costs, and further reduces environmental footprint.

Plasterboard installed together with

Aerolite non-combustible glasswool FOR WARMTH insulation in your ceiling will maintain a THIS WINTER comfortable temperature inside your home by creating a heat-flow barrier between the roof finish and the ceiling. Enhancing thermal properties means that your house will be warm in winter and cool in summer, which is not only important for health, wellbeing and productivity at home, but it is environmentally friendly as well.

Peace and quiet is essential to relaxation, healing and concentration, and for those seeking acoustic comfort, effective sound insulation is a necessity. Protection from external noise adds to the sense of security and privacy in your home, enhancing overall comfort. Sound can also affect your mood and wellbeing, and if your household is busy with multi-functional spaces and several activities co-existing, it’s beneficial to manage acoustics, especially if you have an open-plan design.

According to a survey by SaintGobain, acoustic and thermal comfort is important to 91% of respondents, as most people want their homes to be quiet and

consistently temperate all year round.

South Africa’s mounting energy crisis means we all need to think of innovative ways to save electricity in our homes.

Buildings typically account for 40% of all energy consumed in South Africa. 78% of a building’s energy consumption for space heating, cooling and hot water services can be prevented through a combination of proper insulation and other energysaving techniques.

With the increasing cost of energy, and the lack of resources, it’s worth making improvements to your ceiling, which will not only enhance interior comfort without costing you more on electricity, but also add value to your home. Visit the Think Pink Aerolite website to do an energy savings calculation. www.aerolite.co.za

Design with sustainability in mind from the beginning If asked, most clients would want their buildings to be comfortable, healthy spaces with good energy efficiency. The challenge is persuading them to weigh those long-term benefits against the short-term cost.

Frequently, little attention is given to sustainable design principles early in development.

Yet collaboration early in the design phase can have a significant impact on the comfort and energy efficiency of a building. In a hypothetical building, the goal is to achieve comfortable temperatures and good airflow with minimal use of energy. With the aid of internal airflow studies with an advanced

40 Leading Architecture + Design JUNE/JULY 2021

programme (DesignBuilder), the expected indoor flow rates and temperatures can be predicted.

This guides the design team in placement and sizing of openings (and other features).

A snapshot of the ground-storey temperatures on a windy midJanuary afternoon reveals perceived

temperatures between 23 and 24°C for most of the house. The kitchen on the east would clearly benefit from external shading on the westfacing windows.

In the graph below, the middle data set show how the combination of natural ventilation with HVAC reduces cooling energy by a factor of six. Some effort on window openings can be rewarded by long-term energy savings. But there’s more that can be done. The last set of results shows the outcome from a building where the orientation is optimised, there is foundation-wall insulation, clear double glazing and external louvre shutters. This combination reduces energy use by another factor of four. www.greenplan.co.za

Insulation – the first step to going green Insulation presents the easiest and most economical way to reduce energy consumption required for heating and cooling your home, says Daneel Pretorius, Category Manager of Swartland’s Summit range of insulation and decorative ceiling products. “The better your home is insulated, the more energy you will save when trying to maintain a constant and comfortable indoor temperature.” In fact, it is the first step you should take to improve your home’s overall energy consumption. Pretorius elaborates, “A well-insulated home will be exceptionally energy efficient – requiring very little energy to keep the indoor temperature at a constant and comfortable level.”

He adds that making sure your home is well insulated is not just a nice-to-have – according to the SANS 10400-XA building regulations, proper insulation is actually a legal requirement for any new building.

He says there are different types of insulation, including: Wall insulation: There are two types of wall insulation – cavity and solid wall insulation. Cavity wall insulation is used to fill cavities between the inner and outer wall sleeves. Solid wall insulation is when there is no cavity to fill inside the wall, and as such, the insulation has to be installed on the inner or outer surfaces of the wall.

External solid wall insulation, such as fibreglass or wooden shingles, needs to be weatherproof, and generally covers the entire external façade of the building. Inner solid wall insulation, on the other hand, such as tongue-and-groove XPS insulation board, is installed onto the wall surfaces of interior rooms.

Roof and ceiling insulation: Roof insulation, such as Knauf mineral wool insulation, comprises rolls of soft insulation material that

is installed in the roof between the joists and rafters. Ceiling insulation, such as XPS insulation board, comprises rigid polystyrene foam board that is installed onto a room’s ceilings.

Window insulation: As much as 30% of a home’s heat loss can occur through its windows. With the SANS 10400 National Building Regulations, it is also a legal requirement to meet certain energy-saving criteria.

Double-glazed windows, such as Swartland’s Cape Culture doubleglazed windows, are the ultimate in energy efficiency. A more affordable option are windows with Low E glazing, which comprises glass panes with an ultra-thin coating that ensures less heat passes through.

Floor insulation: Floor insulation creates a barrier between the cold cement foundation and the floor substrate above. In modern homes, there is usually standard insulation between the concrete and the floor substrate; however, in older homes with suspended floors, a product such as XPS insulation board usually needs to be added to the underside of the flooring.

42 Leading Architecture + Design JUNE/JULY 2021

THE BENEFITS OF HOME INSULATION Energy savings: Did you know that an under-insulated home could use up to 30% more energy in order to keep it at a comfortable temperature?

Reduce your carbon footprint: Pretorius notes that it is essential to look for insulation with good green credentials. “XPS insulation board, for example, is 100% recyclable, and its manufacture does not emit any harmful wastes or by-products. Knauf insulation boasts Ecose Technology, which means that it is manufactured from rapidly renewable natural materials and bonded using a biobased technology.”

Better indoor air quality: Insulation helps keep irritating allergens and environmental pollutants out of the air circulating around your home.

Prevents noise pollution: Insulation will not act as a complete sound barrier, but it will definitely help reduce the volume of external noise (and sound inside from disturbing your neighbours).

Protection from moisture and mould: Insulation helps to provide a seal against unwanted moisture and humidity.

A fire barrier: Knauf insulation, for example, has been awarded Euro Class A1, and SANS10177 – Part 5 fire certification. XPS insulation board will be classified as B/ B1/2/H&V in terms of SANS428, which means that although it is combustible, it poses no flamespread hazard. www.summit.co.za

Sika achieves breakthrough in concrete recycling Sika has developed a new, groundbreaking recycling process for old concrete. The old concrete is broken down into the individual parts gravel, sand and limestone in a simple and efficient process, which also binds about 60kg of CO2 per ton of crushed concrete demolition waste. This innovation – with the brand name «reCO2 ver» – will make a significant contribution to reduce the ecological footprint of the construction industry.

According to the European Commission, 25-30% of all waste generated in the EU consists of construction demolition waste materials, many of which could be recycled. Recycling these materials is particularly crucial in dense urban areas, as this is where most old concrete accumulates. Sika has succeeded in developing a highly efficient process that allows for

the separation and reuse of the components of old concrete, as well as increasing the recycled aggregates’ quality.

ADDITIVES FOR HIGHPERFORMANCE CONCRETE Comparative testing of the Sika «reCO2 ver» process has demonstrated that new concretecontaining recycled content performs similarly to an all-new product. Thanks to additionally developed chemical additives, further process optimisations can be achieved, such as the flexibility to tailor specific concrete functionalities.

Paul Schuler, CEO of Sika, says, “In the five largest EU countries alone, roughly 300 million tons of old concrete is generated every year.

With complete recycling of these materials, up to 15 million tons of

CO2 emissions can be captured. We are convinced that our new process has the potential to benefit both our customers and the environment.”

Frank Hoefflin, Chief Technology Officer, states, “With our strong expertise in concrete technology, we were able to develop a completely new recycling process that can be considered a game changer in the concrete industry.

We are already developing

complementary chemical additives and quality enhancers, and are pushing the industrialisation of our new technology.”

MILESTONE IN CONCRETE RECYCLING With the new process, old concrete can be completely recycled and saved from landfill. So far, attempts to recycle old concrete have led to rather low recycling rates, and only 30% of primary material can be substituted by these recycled materials in structural concrete.

The Sika innovation will produce high-performance concrete while sequestering a significant amount of CO2.

SIKA CORPORATE PROFILE Sika is a specialty chemicals company with a leading position in the development and production of systems and products for bonding, sealing, damping, reinforcing and protecting in the building sector and motor vehicle industry. Sika has subsidiaries in 100 countries around the world and manufactures in over 300 factories. Its 25 000 employees generated annual sales of CHF 7.88bn in 2020. zaf.sika.com

AXOR ONE: The essence of luxury Lovingly designed by Barber Osgerby (Edward Barber and Jay Osgerby), the AXOR One collection captures the essence of luxury with its sleek design, purely pleasurable functionality and inimitable class entirely unto its own.

With AXOR One, Barber and Osgerby have reinvented once familiar archetypes, streamlining them for greater design clarity, better functionality and superior control. The result is a collection of slender, elegant forms that embody the principles of compact luxury.

What exactly does compact luxury mean? Jay Osgerby expands on the concept, “Space is really important, and I think what’s happened historically is that the bathroom has always been confined to a really tiny space. Where possible, it’s great to be more generous with the footprint for that room, which is why, in our design concept for a New York loft bathroom, we apportioned a large share of the limited living space in the city for a bathroom as a recreation area.”

AXOR One generously melds purity and sophistication with perfectly interactive precision and control. And while precision control extends to the entire experience with water, there is undeniable perfection in the body of the tap, too. At first glance, AXOR One looks like a simple bent tubular structure. But at a closer look, the tube subtly diminishes in size as it reaches its end, creating a more crafted, elegant look.

46 Leading Architecture + Design JUNE/JULY 2021

Timeless by design, the AXOR One washbasin mixers combine elemental forms with ultra-precise Select technology. Available in different heights, the mixers suit a wide range of bathroom styles and washbasins, including countertop washbowls. The Select taps seamlessly integrate a mechanical handle into the mixer base, which arcs in a beautiful parabolic shape before gently tapering into a curved spout. Distinguished by an elegant flat handle, the single-lever washbasin mixer shares the same visual language of slender silhouettes and balanced proportions with the same exceptional manufacturing quality.

AXOR One overhead showers are a sight to behold, and the hand showers are defined by monolithic forms, driven by the power and relaxation of variable Rain and PowderRain spray types. The AXOR One floor-standing bathtub mixer will definitely catch your eye with its sleek, archetypal form, distinguished by a high parabolic spout.

AXOR One brings the benefit of sheer, minimalist design to life, balancing a radically reduced aesthetic with exceptional functionality. Discover the new trend in sleek, compact bathroom design and find a whole new way of living with water – the One way. www.axor-design.com

GROHE Lineare: Slick minimalist styling for your bathroom We all know that taps are an essential element of any bathroom – not just functionally but visually they can make or break a bathroom design. The style of tap you choose has a big impact on the overall look of your bathroom and, in some cases, beautiful taps can become focal points in themselves. If you want to give your existing bathroom suite a new lease on life, then GROHE Lineare is the ideal option.

GROHE Lineare’s design takes its inspiration from the arc, a shape that offers both strength and lightness. By merging the curves of a circle and the crisp, clean lines of a cube, GROHE Lineare creates an exciting, architectural silhouette, making it possible to combine the taps with both round and square shapes.

“At the core of LIXIL’s design philosophy is solving real challenges with world-leading technology and innovation. We focus on meaningful design – bringing

innovation in areas where we should, not simply because we can. And we cater to all different lifestyles through our unique products,” says Corrie Stride, Leader: Marketing at LIXIL Africa.

Clean and contemporary, Lineare taps are a softer take on the stark reduced lines of Minimalism. A cylindrical body enhances the radial profiles of the lever and spout, resulting in a distinctive collection of bathroom taps. Visual stability is achieved through the parallel geometries of the spout and lever and is highlighted by the GROHE StarLight chrome finish, while GROHE SilkMove technology ensures precise and smooth control of waterflow and temperature. www.lixil.co.za

Telling a Betta design story It’s been said that the best design tells a story. In the case of Betta sanitaryware and Betta Baths, it’s a truly compelling one, featuring high-quality, homegrown products, made in advanced factories – and all using environmentally responsible methods.

ICONIC SOUTH AFRICAN DESIGN If you live in South Africa, there’s little doubt you’ve come across Ceramic Industries’ Betta and Betta Baths products. Their range of high-quality porcelain toilets, basins, urinals and bidets claims close to 50% of the market share in sub-Saharan Africa, and their acrylic baths and shower trays grace building projects from the most exclusive to the most modest.

The two factories have invested significantly in new technologies, and have a workforce that’s highly skilled. Among their greatest assets is Vidal de Sa, one of the world’s foremost modellers, who creates Betta’s appealing designs.

WORLD-CLASS TECH Almost all Betta porcelain products are manufactured using high-pressure casting, ensuring consistency, while cisterns and lids are cast and fired together to ensure a perfect fit. Automated robots carry out glazing, with individual spraying patterns for each and every piece.

In the Betta Baths factory, products are made using state-ofthe-art vacuum-forming machines that ensure consistency, whether it’s a strikingly modern one-piece seamless bath or a budget-friendly drop-in. The products are finished with automated cutting, trimming and edging to ensure perfect positioning for wastes, drilled holes for handles and overflows. For a nominal fee, the factory is also able to convert any of their baths into jetted spa baths.

EARTH-FRIENDLY BATHROOMS Ceramic Industries is committed to environmentally responsible

production methods, recently instituting a company-wide project with the aim of reaching zero carbon emissions. For several years already, the Betta factory has made use of rooftop solar panels to generate 1MW of electricity for manufacturing processes. In addition, they make use of heat recycling, channelling hot air from the kilns back to the casting room – no external heat is needed to heat the boilers there.

Even when the products leave the factory, they remain positive

contributors to ecological living.

Innovations in Betta toilets result in a swimming pool’s worth of water saving in a year for a family of four.

At a time when customers are looking to buy local and are increasingly eco-conscious, Betta and Betta Baths products tick all the boxes without compromising on style. Now that’s a good South African story, just when we can use one. www.ceramic.co.za

Three new security products from Trellidor Security barrier manufacturer Trellidor has launched two new cost-effective products designed for homes in eco-estates, golf estates, cluster housing and gated communities and one, a rolling shutter, aimed at facilities that require exceptionally strong protection.

PROUDLY SOUTH AFRICAN LOCKDOWN SHUTTER “Our new Lockdown Shutter provides extraordinary strength combined with built-in safety

features. It’s a first for South Africa in that the non-mechanical locking system does not rely on the motor, so it functions even during power outages,” says Trellidor Marketing and Sales Director Peter Rawson.

This roller shutter has a neat appearance and offers outstanding strength under attack. It is the perfect protection for areas such as pharmaceutical storage facilities, safe zones within commercial or residential buildings, data storage rooms and other sensitive installations.

The shutters are fully motorised and operated by a hand-held remote control. Once closed, any attempt to lift the shutter with vertical force tightens it further into the closed position, making it impossible to lift even with a forklift.

A manual override crank handle is provided for emergency opening and shutters are fitted with an obstacle detection system to prevent accidental locking.

CUSTOMISED ESTATE SHUTTERS “We’ve also introduced an Estate Shutter that looks similar to our popular louvred Security Shutter.

The main difference is that it has been engineered for lower crime risk areas such as homes in secure estates where access is tightly controlled. It is an affordable shutter that does not compromise on strength or style,” says Rawson.

“Our product engineers have paid attention to details such as colour-coded hardware, hidden strengthening mechanisms, uniform frames across all configurations, and a variety of bottom tracks to suit different installations to make this a

52 Leading Architecture + Design JUNE/JULY 2021

versatile and cost-effective window and door solution.”

BARELY-THERE ESTATE CLEAR GUARD Trellidor introduced Clear Guard see-through security mesh screens to the South African market over 10 years ago. It has proven to be a winner for projects requiring protection that is virtually invisible, and has a multitude of uses like blocking out insects and other wildlife, filtering UV rays and intense heat to reduce internal temperatures and allowing fresh air to flow inside.

“We’ve now expanded this range to include an Estate Clear Guard hinged design that is reasonably priced, multi-purpose and good-looking. It has a neat aluminium frame and a see-through mesh insert. As expected of all Trellidor products, it has built-in strengthening features, enhanced by a Trellidor locking system. Other configurations are being added to the Estate Range as we develop them,” says Rawson. www.trellidor.co.za

BEAUTIFUL ESTATE SHUTTERS Trellidor has made it even more affordable to get gorgeous, custom-designed, aluminium louvre shutters for your home at a price you can afford. All without compromising on safety. Our brand-new shutters in a colour of your choice will add style and elegance to your interiors, so fit them to all your doors, windows and around your patio.

Gunnebo launches security gate monitoring app In May this year, Gunnebo Entrance Control launched EntraLinq, a new software as a service (SaaS) application providing for the remote monitoring and control of office building access.

The app, which connects to Gunnebo pedestrian speed gates, delivers both intuitive yet in-depth visibility of building access and performance, serving as an easy at-hand decision-making support tool for managing people-flow, maintenance and security as efficiently as possible.

EntraLinq uses the intelligence and connectivity provided by Gunnebo gates to offer the customer complete control and visibility of their access security.

Whether for a single access point or for multiple sites around the world, the application provides complete onsite and remote access via a smartphone or tablet.

“This is a game changer for the market. Our gates have become more and more intelligent and connected; it is now time to harness the potential of the data they generate into intuitively designed applications that support our customers’ processes,” says Henrik Lång, Product Manager.

The app is designed to address three core functions that enable customers to easily and efficiently manage the diversity of needs for building access.

• Control: To provide full remote control of multiple connected access points to optimise peopleflow and allow more focus on hospitality.

• Process: To provide visibility of real-time and historical people-flow process data, helping security and facility management to gain insights and foresee behavioural patterns necessary to plan and streamline the deployment of security resources.

A rational design report is much more than a fire-risk checklist

By Michae l van Nie k e rk , C E O, A S P F ire

What is a rational design report? A rational design is a performancebased design that takes into account the behaviour of a building during a fire, meaning the structure must be designed accordingly to minimise any potentially devastating impact. However, a lot of these rational design reports are actually just checklists for the prevailing regulations.

Does the design comply with the requirements of the National Building Regulations and Building Standards Act, 1977 (Act No. 103 of 1977), Fire Protection, as set out in SANS 10400 Part T: 2011? This is critical, because rational design is essentially the performance-based design of fire safety, prevention and suppression mechanisms and strategies in a building in order to provide the same or better firesafety levels as prescribed in the National Building Regulations.

‘Checklist’ rational design reports run the danger of not including an adequate fire-risk assessment. The people who compile them do not have a proper understanding of what they are trying to design. If you do not know what you are trying to protect, you cannot develop a suitable system to mitigate that risk. They also do not take into account the full ambit of risks that needs to be assessed.

These include internal risks such as fire, life safety and property.

But what about an indirect risk like adverse economic impact?

This is where the loss to a business through ongoing interruption has a significant impact on business continuity. Also, what about indirect environmental risks, such as ground- and stormwater contamination from firewater effluent, or the impact of smoke and fire on a neighbouring building?

These are some of the factors that have to be taken into account if a rational design report is to include the total scope. However, we find that these reports often do not address these elements adequately, let alone provide adequate protection.

The precise BS 7974 methodology mandated by SANS 10400, for example, is not adhered to. This is not only an inadequacy in the reporting process, but represents a major problem with serious health and safety repercussions.

Another red flag is that local authorities often do not understand the full parameters of a performance-based design engineering solution. For example, when recently compiling a report for a COVID-19-compliant hospital, we found ourselves going around in circles with regard to certain aspects, and as a result it took months to have the report approved.

Here the stumbling block is that the local authority in charge of approving such rational designs often lacks the technical competency to properly understand the engineering science and

58 Leading Architecture + Design JUNE/JULY 2021

mathematics underpinning that particular report. As professional engineers, we assume full accountability and responsibility for the reports we compile.

Again, it is all about a performance-based solution.

It is not about interrogating the process we follow and the calculations we derive at, but how we satisfy the risk requirements established upfront, and thereby conclude that a particular building is safe. That is an issue that needs to be resolved nationally.

So where does the skills gap with fire engineers lie? I do not think it is an issue of technical competency; rather, it is down to experience.

For example, you do not qualify as an accountant and immediately commence auditing. First, you have to complete your articles in order to prove your competency. Similarly, a registered fire engineer has to have a body of work behind him or her in order to be capable of carrying out a rational design.

The Engineering Council of South Africa (ECSA) recently changed the requirements for qualifying as a

competent person in this regard.

I think this is going to change the landscape significantly, as it highlights where the deficiency lies, namely the proper assessment of who is sufficiently qualified to carry out rational designs.

For example, we have conducted numerous rational designs in highrisk areas that comply fully with the SANS 10400 requirements in terms of BS 7974. We are very thorough, which is why we do not generally have any issues in getting our reports approved. Our experience includes solvent-extraction plants, explosives manufacturers, packhouses, hotels, shopping centres, hospitals and even tyre storage facilities. www.aspfire.co.za

Ultra-Span helps deliver new healthcare facilities across South Africa When you’re building hospitals and healthcare facilities, just as for any other project, there’s a need to balance safety, ease of construction, longevity and, of course, costs.

Here in South Africa, the construction industry has found a real appetite for MiTek’s UltraSpan system as it meets a lot of the requirements demanded by government regulations, designers and healthcare providers alike.

Ideal for spans of 6m and up to 20m or more, Ultra-Span is a prefabricated, light gauge steel roof truss system. It’s lightweight,

compact, easy to transport, handle and install, and is a good solution for healthcare facilities where non-combustibility is a vital consideration.

While timber may have been used in the past, the Ultra-Span system offers several benefits that make it a much better choice all round. As well as being fire-proof, the system is more durable, making it a good long-term investment.

Its galvanised coating means it’s resistant to fungus and mould, and is fully vermin-proof – making it the more hygienic option.

Not only is the system

60 Leading Architecture + Design JUNE/JULY 2021

lightweight and easy to erect on site – once installed, it needs minimal maintenance, helping to keep costs down once the site is up and running.

WHEN OFFSITE MEETS ONSITE Like other products in MiTek’s range, Ultra-Span is constructed off-site, meaning that when it arrives at the client’s site, it is already cut to size and ready to install. If skilled labour is in short supply, which is often inevitably the case in the more remote locations, we provide a trainer who can work with the local workforce to train them in how to safely and quickly erect the trusses.

Even when workers are unfamiliar with the system, it’s still quick and easy to set up. The lightweight nature of the construction means the trusses are easy to handle, even for novices, and the resulting rapid assembly means the construction team can soon move on to the next stage of the build.

While the Ultra-Span system clearly offers benefits in costs, versatility, ease of handling, speed of assembly, longevity, safety and hygiene, these aren’t the only factors in its favour. Architects like to specify the material as it’s visually appealing, making the buildings more aesthetically pleasing for certain projects’ requirements.

A number of hospitals across SA have already specified and installed Ultra-Span, including Mediclinic Vergelegen in Somerset West, Mediclinic Stellenbosch & Paarl in the Western Cape, and Helderberg in Cape Town.

Of course, Ultra-Span isn’t just a great solution for hospitals – it has found applications across a wide building range, from affordable housing units, factories and warehouses, to universities and offices. But there’s no doubt it’s delivering for the healthcare sector in SA, for all the right reasons. www.mii.com

STOPPING FIRES BEFORE THEY START! ASP Fire is able to conduct fire-risk assessments and Rational Fire Designs for shopping centers.

Fire plans have to be resubmitted for approval whenever a tenant changes, or if the internal layout of a shop changes.

Ceiling void smoke detection, void fire protection and the activation of smoke extraction systems by tenant fire panels are areas often ignored when shopping centers are built.

Most tenants are not aware of the specific requirements for automatic fire detection and alarmsystems and their obligation to install them.

Safal Steel in good global company with Zincal® coated steel

One of the fastest growing types of metal roofing available is that which uses a coating alloy of aluminium and zinc with a specific formulation patented by Bethlehem Steel some 40 years ago. Increasingly, it is being used in projects all over the globe for both its durability and proven performance in field service.

It is widely referred to as 55%Al-Zn coating technology.

In America and abroad, this product has been sold commercially since 1972 under the name Galvalume®. Bethlehem Steel later licensed other major steel companies to produce and sell the product under patent. All products worldwide use the same coating alloy and technology, and benefit from global testing and performance trials.

In Africa, the Safal Group is the sole licensee of this coating technology, and sells its coated steel under the registered name of Zincal®.

55%AL-ZN GLOBAL PRODUCTION ON THE RISE DESPITE COVID-19 Despite the COVID-19 pandemic during 2020, annual licensed 55%Al-Zn production rose by 2.1% in that year to reach almost 9,1 million metric tons, and a cumulative worldwide total of over 180 million metric tons since inception.

WHAT IS THIS COATING ALLOY MADE UP OF? A carbon steel base sheet is continuously hot-dipped to coat it with an alloy consisting of 55% aluminium, 43.4% zinc and 1.6% silicone. This alloy prolongs the life of the inner steel core by protecting it from perforation due to exposure to the elements. The specific percentages of metals in its formulation allows for the best characteristics of both aluminium and zinc metals to perform in optimal synergy for lasting durability. Sourcing your 55%Al-Zn

64 Leading Architecture + Design JUNE/JULY 2021

coated steel from a licensed supplier is the only assurance that you will obtain this length of service life.

THE SAFAL GROUP – THE FIRST, AND STILL THE LARGEST MANUFACTURER OF 55% AL-ZN IN AFRICA The Safal Group was the first and remains the foremost producer of 55%Al-Zn coated steel on the continent. The group has three steel coating plants: in South Africa (Safal Steel in Cato Ridge), Tanzania (ALAF in Dar es Salaam), and Kenya (Mabati Rolling Mills in Mombasa).

Safal Steel sells its metallic

coated product under the brand name Zincal®. Colour-coated Zincal® is sold as Colorplus® and Optima® in a range of colours that are both durable and beautiful.

Test sites are located in many areas of Eastern and Southern Africa, proving that the service life of Zincal®, Colorplus® and Optima® provide the lasting value and performance for which they are known and trusted by millions of building owners, professionals and specifiers throughout the continent. www.safalsteel.com

SAFLOK 410 proven to be the best Safintra South Africa, a member of the SAFAL Group of Companies, has over the last 30 years established itself as a leading supplier of worldclass roofing systems in the South African market. A firm favourite among the design community, and with Service Centres strategically placed over 10 regional hubs, the company is ideally positioned to provide tailor-made building solutions that are unique to a particular region.

A fitting example of this approach is none other than the SAFLOK 410 profile, which has over the last decade established itself as the product of choice among industry professionals when it comes to metal cladding. With over 10 million square metres successfully covered over this time, and not a single sheet lost through deficient performance, the product is ideal for the demanding weather challenges in the product’s traditional market space of the Western and Eastern Cape regions.

Skilful strategic thinking during the challenging economic times presented by COVID-19, has

prompted the Safintra brains trust to centralise its operations, and to avail SAFLOK 410 mills for the Gauteng and KZN markets where dramatic changes in weather patterns of recent years have presented a unique opportunity for narrow width concealed fix systems.

As part of this endeavour, the SAFLOK 410 profile was tested at the CSIR facilities in Tshwane by a leading wind load specialist and respected engineer, Dr Adam Goliger. Not only to update available test data, but also to position the product as one of the few in South Africa with credible test results in line with the requirements of the latest National Standards. Astounding results were achieved, placing SAFLOK 410’s performance parameters at the very apex of the concealed fix landscape.

Of course, such unprecedented and excellent results had to be celebrated and shared with the industry, and consequently Safintra embarked on a regional roadshow for Gauteng and KZN to

66 Leading Architecture + Design JUNE/JULY 2021

introduce SAFLOK 410 to respected captains of industry.

A selected group of key influencers and recognised industry leaders, by invitation, joined Safintra as eager participants on a four-week SAFLOK 410 roadshow to showcase the brand and establish it as the high-performance concealed fix system of choice in the industry.

The event can only be described as an overwhelming success,

established relationships were reinforced, and new friendships were moulded as SAFLOK 410 quickly carved out a keen fan base among attendees.

Once again, Safintra has unequivocally demonstrated why they are widely regarded as the leader in roofing innovation and supplier of world-class roofing systems. www.safintra.co.za

Re-imagining commercial space with Gyproc’s Thin Wall Solutions Thin drywalls, around 95mm wide, have been used in the commercial office environment for many years. A challenge faced by interior designers, developers and occupants has been the acoustic performance and rigidity of these walls, specifically the ‘knock-knock’ or hollow sound, and lack of privacy as a result of acoustic flanking.

Gyproc, however, has over many years developed thin walls that provide both rigidity and brickequivalent acoustic performance that additionally provide the benefits of speed, sustainability and design flexibility.

The backbone of the Gyproc thinwall solution is the Gypframe® UltraSTEEL® 51mm stud and track wall-frame. Manufactured from the highest grade light gauge steel, using the patented UltraSTEEL® process, it is possible to convert spaces previously occupied for large open-plan commercial use into smaller units when paired with either the 63,5 or 102mm Gypframe® UltraSTEEL® wall frames as dividing walls between tenants.

Key to the rigidity of the wall system, the stud must offer two key performance attributes: resistance to deflection and high screw retention. The UltraSTEEL® process, only available in Gypframe® stud and track products, offer both. This process creates a dimpled effect across the surface of a pre-hot dipped galvanised sheet of steel.

This new dimpled sheet of material demonstrates performance-enhancing characteristics for the base strip steel, providing higher strength capacity from lighter gauge

material. The process effectively work-hardens the steel with two mating rolls, and has the benefit of increasing the load-carrying capacity of the flat sheet. During the process, the effective thickness of the material is increased to that of the original thickness, plus the depth of the ribbing. Other benefits include an ability to resist deformation within fire tests, improved screw retention, and the production of an attractive and aesthetic component.

The eventual acoustic performance of the installed wall is determined to a significant extent at design stage, ensuring the wall extends from floor to soffit or roof purlin and truss structure, incorporating deflection heads where required, ensuring that backbone will provide the performance demanded when reimagining the usage of the space.

Drywalls installed without the appropriate and high-performance insulation, typically in office space, perform poorly from an acoustic perspective, with a cavity that amplifies sounds and offers little privacy. Isover’s Cavitylite® glasswool insulation, supplied in 51mm thick rolls, provides a solution that does not promote corrosion of the frame, is non-combustible and does not sustain vermin.

Cladding the insulated wall frame provides the base for the finished wall; Gyproc’s extensive range of RhinoBoards® provide fire, moisture, fixability and impact resistance aligned with the intended use for the space.

The correct fixing of the boards to the wall-frame is the next crucial aspect in ensuring

68 Leading Architecture + Design JUNE/JULY 2021

a high-performance thin wall.

Stiffness and associated acoustic performance combines the characteristics of wall-frame, board and drywall screws. Spacing of fixing and appropriate screw type is crucial and must follow the technical detail guidelines in order to deliver the ultimate thin wall.

Jointing and final aesthetic finish is typically influenced by space use. Flush plastered, tape and joint, or tiling finishes all rely on RhinoLite® plasters to fill the board joints and provide a

suitable base for a final painted or papered finish.

As conversions and adaptation of commercial and residential spaces are increasingly considered and adopted, Gyproc wall systems offer a low-mess, quick and highperformance solution. The Gyproc technical team provide installers with project-specific technical details, supporting successful execution of thin-wall, lowweight internal wall solutions. www.gyproc.co.za

New look for SA’s no.1 plaster brand South Africa’s leading plaster manufacturer – SaintGobain Gyproc – is rebooting its entire range of Rhino Plasters! Gyproc’s fresh, new look and streamlined packaging aims to reflect the brand’s commitment to innovation and sustainability.

“Whilst the packaging on the outside reflects change, the high-quality and trusted product that our customers have come to know and expect remains the same,” says Anton Marais, head of product at SaintGobain Gyproc. “We are constantly innovating to make living spaces more comfortable, cost-effective and sustainable, and are confident that our new packaging aligns with these ideals, as well as with our overall purpose – making the world a better home.”

As South Africa’s number-one plaster brand, the RhinoLite® range is GreenTag Certified and achieves a smooth finish when applied. The new look will be rolled out over the full range of products, including multipurpose plasters, skimming plasters, jointing compounds, moulding plaster and setting adhesives.

Celebrating over 90 years of rich history and local heritage, Gyproc products are manufactured locally in Cape Town and Germiston, and the brand supplies both the local and international markets with trusted products such as RhinoLite® and RhinoGlide® registered as trademarks in 1979. www.gyproc.co.za

TAL launches waterproofing compound for residential applications TAL, a division of Norcros SA, has launched a new cementitious waterproofing compound into the market, which forms part of their recommended multi-level system for a successful shower installation.

“We are pleased to introduce TAL Sureproof Shower to the market. The product is a cementitious quick-setting, tough, flexible and fibre-enriched waterproofing compound, ideal for waterproofing showers and bathtub surround walls in residential applications, prior to tiling. It’s also very easy to apply,” says Sharon Margon, TAL Technical Advice Supervisor.

The product is fibre-enriched, which provides enhanced flexibility as well as crack-bridging properties, and can be used to fill small hairline shrinkage and static cracks (less than 2mm wide). It requires no reinforcing membrane when used in ground-floor applications.

When applied onto rendered and screeded surfaces that are cured and free of surface contamination, no priming is

70 Leading Architecture + Design JUNE/JULY 2021

required prior to using the new product from TAL. Simply add the TAL Sureproof Shower to approximately 1.9-2L of cool, clean water and mix to a paintable slurry.

Apply using a builder’s block brush, painting two coats onto the shower walls and floors in cross directions, with the second coat being applied once the first coat has dried sufficiently.

The product is fully compatible with cement-based tile adhesives and can be tiled directly onto without the need for primers, once cured. “Due to the impervious nature of the waterproofed substrate, only rapid- or quick-setting tile adhesives should be used,” Margon continues.

TAL Sureproof Shower is available in a 5kg bucket. It is classified as a CMO membrane material – Cementitious Liquid-applied Water Impermeable Membrane (CM), with minimal Crack Bridging Ability at Low Temperature (O) in terms of EN14891. www.tal.co.za

Fusion ideas

Accurate measuring, easy reading, wireless transfer: Robust laser measures from Bosch for professionals The laser measures GLM 50-27 C and CG Professional from Bosch combine high robustness with a fast, convenient measurement, as well as simple documentation and processing of measuring data. The tools differ in the colour of their lasers: the GLM 50-27 C Professional operates with a red laser diode, the GLM 50-27 CG Professional with a green one. This improves its laser point visibility, particularly in bright areas such as during installation work in front of large window areas in concrete or steel frame construction. Both tools measure distances of up to 50m to an accuracy of ±1.5mm and are particularly robust: they have an ABS housing with stabilising ribs and shock-absorbing rubber casing, as well as a particularly break-proof display with a tear-resistant silicone keyboard.

They thus remain undamaged even after falls onto concrete from a height of 1.5m. Furthermore, both laser measures are IP65-certified and, thanks to their all-round rubber seal, are both jetwater protected as well as dustproof. www.bosch.africa

Colour power – exploring the impact of colour in interior design Pablo Picasso once said that “colours, like features, follow the changes of the emotions”. Artists such as Picasso and interior designers have for centuries believed that colour can hugely affect moods, feelings and emotions. Perhaps this is why the design and colour choice of a room can often leave us feeling a sense of calm, alive with a burst of energy or, in other cases, more grounded.

Dulux Colour Expert, Palesa Ramaisa, couldn’t agree more. “When decorating, it is always important to consider the desired feel of the space that you are in. Think calming blues, grounding earth tones and energising yellows. The psychology of colour is such an important factor, not just within the marketing industry, but also within the world of design where it holds the power to impact a room more than any other factor.”

INTERIOR DESIGN COLOUR PSYCHOLOGY As we continue to work from home, you may feel the need to spruce up your home office. Ramaisa suggests incorporating an uplifting combination of neutral shades paired with subtle pastel colours, which will create a space that promotes

concentration. Playing around with different paint techniques can also easily change a plain wall into something exciting.

For your little ones, look at adding more vibrant, stimulating colours such as toned-down yellows paired with warm neutrals or rich orange tones, which spark creativity, balance, freedom and allow them room for expression.

“If your living room is on the large side, one of the simplest ways to create a more intimate feel is by breaking your room down into smaller zones. You could paint one of your walls a deep, vibrant colour or just a few shades darker than the rest of the room. You could also try a bright colour on the inside of bookshelves or on the woodwork around windows.

Creating those cosy zones within your lounge area will not only give the room a focal point, but will help draw the eye in,” adds Ramaisa.

If you’re afraid of making longterm colour choices, a good way to test out the impact of colour on your mood or space is to start small.

Ramaisa explains that you can easily include a few statement pieces or finishing touches to help test out the space.

74 Leading Architecture + Design JUNE/JULY 2021

“Bring the outside in with toning shades of green, combined with deep blue, for a bedroom that connects you back to nature.

Finish the effect by adding a touch of Dulux Colour of the Year, Brave Ground. Here, painted shutters and coordinating cushions anchor the look, while a natural wicker chair completes the look.”

UP THE ANTE BY INCORPORATING COLOUR AND PAINT TECHNIQUES Another way to impact the mood of a room is by incorporating different paint effects.

Are you looking for an alfresco feel in your dining area? “Paint a deep blue square against a pale blue wall, and frame with a band of Dulux Colour of the Year, Brave Ground, to give a mockwindow effect. Fresh and calming, this will bring an airy feel to any interior dining space and, mixed with lush greenery and natural materials, will make you feel as if you’re outside,” adds Ramaisa.

Whatever mood you’re after, there’s always a colour that can help evoke a desired emotion. www.dulux.co.za

The questions you need to be asking your pool cover supplier As pool covers evolve and the demand continues to grow in South Africa, the local pool cover market is starting to see numerous smallscale producers start up by offering cheaper products but not offering the same quality. When it comes to child safety, the details really do matter and, when faced with a drowning hazard, your pool owner will be glad that the tough questions have already been answered.

“Cutting corners is just such a risk for pool covers. In fact, it can be called neglect as it really can lead directly to loss of life. We have been covering pools for nearly 30 years, and as such, we have a clear understanding of what goes into a quality pool cover and a perfect installation,” says Andrew Crafford of PowerPlastics Pool Covers.

These are some of the questions that designers and architects should be asking the pool cover supplier before accepting any quote.

SOLID SAFETY COVERS FOR CHILD AND PET SAFETY • What is the weight tolerance, and have they done adequate

•

•

• •

•

•

testing? Can they share verified data or case studies?

Does the cover comply with the SABS Standards SANS 10400-D and SABS 10134?

Could a child release the cover’s fastenings / ratchets? Could an object measuring 9cm fit under the edge of the cover (the size of a child’s head)?

Does the solid cover have drainage holes to prevent water pooling on top of the cover (a drowning risk)? Is the cover completely water-free 10 minutes after rain?

Is the installer accredited by an industry expert or body?

Is the PVC material stabilised for the UV environment? And is it 600gsm? Does it have a strong internal scrim? Or is it without structure?

Is there a good colour range, allowing the designer or architect a chance to blend the outdoor area’s aesthetics?

Are the finishes up to standard?

The smallest design element can also have an aesthetic impact.

76 Leading Architecture + Design JUNE/JULY 2021

For example, adding rubber end caps to the aluminium batons on a solid safety cover can look unsightly, besides which they are not needed.

• Are the aluminium batons specifically manufactured for solid safety pool covers?

THERMAL / BUBBLE COVERS • What shape is the bubble? Early thermal material used round bubbles but the bubble had inherent stress points, which was a design issue. Any round bubble cover today is likely to just be packaging material dyed blue and will disintegrate into blue confetti. Delamination is also common in cheap covers.

The industry has moved on and GeoBubble is the new standard, with a figure 8 / dog bone bubble shape. There has been significant investment in the awardwinning GeoBubble technology.

• Do the performance figures add up? Make sure the test-house data stands up and has an academic body behind it.

• Do they state that a thermal cover can protect small pets from drowning? A pool cover lying on the water is not load-bearing and it is not sealed off on the sides.

Many animals drown because their owners think the thermal cover supports them. Only a solid safety cover gives absolute peace of mind.

• Does the cover come with care guidelines? Correct cover maintenance is critical to longevity. If the supplier has not given this any thought or can’t advise you, walk away.

“A reputable pool cover supplier is one that stays on top of trends and tweaks design all the time. It also invests in training and quality checks. Unfortunately, the small businesses don’t always have access to such resources. It is one thing to copy a design but the finish, materials and workmanship such as PowerPlastics Pool Covers’ can’t be compared,” concludes Crafford. www.powerplastics.co.za

Paving and kerbing up the Mall of Thembisa The magnificent 44 690m2, twolevel Mall of Thembisa, situated in Clayville near Thembisa, Gauteng, opened in late 2020 and boasts over 140 retail stores, food courts, an entertainment centre, promotional courts and a gym.

The Mall offers dedicated public transportation areas and sufficient customer parking and entrances to meet the high volume of expected foot and vehicle traffic. Technicrete supplied the majority of the precast concrete kerbing for the access roads, building perimeters and the parking areas.

Loftie Eaton, Site Manager at Labucon, the main contractor for services and earthworks on the Mall of Thembisa project,

comments that the good quality of the Technicrete kerb product and their closeness to site were factors in their favourable selection to contribute to the project. “Labucon have worked with Technicrete before, so we know the quality of their products. With a project of this size and the high level of vehicles and people expected to visit the Mall, it was essential that kerbing be not only aesthetically pleasing and blend in with the design of the Mall, but also offer a long lifespan. The fact that they are also a local company with manufacturing facilities close by was a major advantage for this large project,” says Eaton.

Technicrete supplied 10 000m of

their Fig7 1000mm kerbs, 10 000m of Fig 7 330mm kerbs, 500m of their Fig 8C 1000mm kerbs, and 1 100m of their Fig 10 1000m kerbs – all of which are precast concrete.

1 700m of grey Garden kerbs 500x150x75mm, and 12 012m2 of grey Double Zig Zag 60mm grey paving blocks were used for edge restraint on the pathways.

The Fig 8C kerb is a heavy-duty kerb that is particularly suited for commercial developments, while the Fig 7 kerb has a ‘splayed’ profile, which is preferred for developments where vehicles may need to ‘bump up’ onto a verge in an emergency. The Fig 10 kerb is a light- to medium-duty bull-nosed edge restraint, normally applied

around islands in parking areas.

The Double Zig Zag interlocking pavers are ideally suited to shopping centre pavement foot traffic as they offer a continuous, hard-wearing surface overlay, which makes them an economical and aesthetically appealing choice.

Arno Smuts, Sales Consultant for Technicrete, comments that the Technicrete products selected for the Thembisa Mall are manufactured locally to the highest specified standard, hence the ability of the products to offer a superior longevity to a project that will have an enormous amount of vehicle and pedestrian traffic. www.technicrete.co.za

Innovative virtual showroom offers immersive access to GROHE products

Viewing the world-class range of GROHE products has never been easier.

In a ground-breaking, first-of-its-kind offering in Africa, GROHE products can now be experienced first-hand at GROHE’s virtual showroom.

“Our brand-new virtual platform allows customers to view and experience GROHE products and innovations from the comfort of their home or office,” explains Corrie Stride, Leader: Marketing at LIXIL Africa.

“Videos, 3D renderings and detailed technical drawings provide a completely immersive experience, helping customers to research, plan and design every aspect of their new or revamped kitchen or bathroom.”

GROHE is one of the world’s leading manufacturers of sanitary fittings. Headquartered in Germany, the company is known for the quality, versatility and ingenuity of its products and has become a firm favourite in Africa.

“The showroom will be as valuable for architects, interior decorators and installers as it is for consumers,” Stride adds. “Consumers will find the showroom useful for product designs and inspiration, while professionals will enjoy having all the necessary technical specifications at their fingertips, and be able to demonstrate GROHE’s various product ranges and

innovations to their customers.”

The showroom offers visitors the chance to see what the various GROHE products look like in modern bathroom and kitchen settings, which have been designed based on the latest industry trends. It also provides insight into how some of GROHE’s more complex and innovative offerings work, including GROHE SmartControl technology and GROHE Blue. While the former allows you to choose the outlet, waterflow and temperature every time you shower, the latter serves as a high-performance filter, cooler and carbonator to deliver superior chilled, sparkling or still water on tap.

“Although the pandemic made the showroom more relevant than ever before,” Stride adds, “we have always wanted our products to be available to our customers in innovative and meaningful ways. We are excited to invite our customers into to a real-life environment, where they will be immersed into a tangible GROHE experience.”

Curator sofa Originally designed by OKHA for a private art collector and tribal arts dealer, the Curator was conceived as a singularly sculpted form on which to recline, rest and reflect upon the artworks of his collection – hence the name Curator.

The Curator would itself seamlessly merge with the collection, with its honed and chiselled form that alters from every viewing angle, resulting in an unlikely balance from seemingly random but intuitive asymmetry.

The Curator is certainly one of the more provocative chaises longues to be launched in the design world and has been described by Adam Court, OKHA’s Creative Director,

as “an abstract landscape honed into seating design”.

Selected for acclaimed architecture and interior residential projects Beyond (SAOTA) and Hillside View (ARRCC), Curator creates a sense of contemporary drama when paired with more classical pieces. The bar and bar lounge of the SAOTA-designed home Beyond, which featured in the February/March 2019 issue

82 Leading Architecture + Design JUNE/JULY 2021

of Leading Architecture + Design , hovers over the pool and showcases the Curator couch together with a Kenneth Cobonpue chair and Martie Kossatz artwork, and dazzling views of the Atlantic Ocean.

The ARRCC-designed home Hillside View employs the Curator’s geometric curves to lead the eye to various focal

points throughout the space, from a striking blue rug below to mounted artworks by shapemaster artist Andrzej Urbanski of Everard Read gallery.

The Curator’s smoothed rock-like shape can be tailored in a range of premium and bespoke fabrics or leathers. www.okha.com
