MESSAGE FROM THE PRESIDENT

FROM THE PRESIDENT’S DESK Let me start by extending my heartfelt thanks for attending Master Builders SA’s congress in Cape Town on 8 September 2023. Based on the feedback we received from delegates, it was a huge success.

Your presence and participation helped make it a memorable and engaging experience. We hope that you gained valuable insights and connections from the event.

As was mentioned there, the industry is still experiencing steady decline since 2017. After the Covid-19 shutdowns occurred, material costs rose due to limited availability, transportation delays and lockdowns in various countries. Building material costs have increased by 33% since the coronavirus first struck the country.

According to the report Construction in South Africa: Key Trends and Opportunities to 2025, we can expect the industry to stabilise at an annual average growth of 3,1% between 2023 and 2025.

02

Most businesses are experiencing gradual recovery from the impact of the pandemic.

It is hoped that government spending will support this recovery. In 2021, it announced its plan to invest R791,2 billion in public-sector infrastructure spending over the period 2021-2024.

The only concern is the report from Stats SA, which reported that since April 2020, only 26% of businesses in the construction sector were still operating, with 74% in temporary closure.

The industry is pinning its hopes on government spending to support recovery. The situation is now dire and we are pleading with the state to implement and activate infrastructure projects in order to propel economic growth in the country and revive our industry.

COVER STORY

MADE TO LAST, PROTECT – AND ENHANCE The Clay Brick Association of SA (CBASA) represents clay brick and paver manufacturers across southern Africa. It drives inclusive, sustainable practices in the industry and inspires energyefficient, stylish and contemporary architecture. It also offers free technical and construction guides on its website, compiled by experts.

With stylish, timeless appeal and impressive sustainability credentials, the enduring hues and textures of clay brick look beautiful for a lifetime. Clay brick is a natural insulator against winter cold, summer heat, humidity and noise.

Clay brick is well known for its impressive strength, stability and maximum fire-resistance. Genuine clay brick is the original long-life, no-hassle building material – it

does not burn, rot, tarnish, fade, rust, scuff, peel, erode or burn, and needs minimal maintenance. The average clay brick structure lasts over 100 years and often far longer,

as attested to by the Castle of Good Hope in Cape Town – South Africa’s oldest building – which remains as sturdy and solid as when it was built, back in 1684.

Clay brick structures have impressively high load-bearing capacity, high dimensional stability and compressive strength (7MPa for NFP bricks to more than 50MPA for facebrick extra and engineering products). All of these qualities limit cracking and ensure structural integrity. This means that their embodied energy is dissipated over their life-cycle, reducing their carbon footprint.

SAFE AS (CLAY BRICK) HOUSES Since clay bricks are fired at temperatures of 1 000-1 200˚C, they can resist this level of heat without damage, making them effectively incombustible. This

means they cannot contribute to the start or spreading of fires.

They are also unable to conduct electricity or lightning.

In addition, they can withstand saturation from rain and floods, as they absorb water so that damp walls dry out very rapidly without damage or staining. However, should staining occur or mortar crumble after long exposure to the elements, the bricks are easily replaceable – and can be re-used.

Their inherent strength also makes them hail-resistant, and – crucially – able to withstand vandalism, civil crime and unrest.

Moreover, clay bricks can withstand the high acid or alkaline discharges which occur in severe climate zones and industrial areas.

In coastal areas, they resist the corrosive effects of salt sea mist, high water tables and soluble sulphates in the soil.

And within structures, they have the density to support built-in cupboards, heavy shelves and wall-mounted fixtures, while

double-lead brick walls protect conduits and piping without reducing accessibility.

STILL THE WISEST CHOICE With these many advantages, which have been tried, tested and proven for centuries, clay bricks remain the most economical, stress-free and logical choice for almost any construction project.

These bricks have long been ubiquitous around South Africa, from private residences to schools, hospitals, churches, forts, lighthouses and social infrastructure. Moulded from South African soil, they have served and protected South African families for many generations – and will continue doing so for generations to come.

CBASA is proud to represent those who manufacture them.

Emphasising the importance of technical and vocational skills development alongside academic and professional streams in South Africa’s education is the primary objective of the annual SasolKagiso Trust Interprovincial Technical Skills Competition. The finals of this year’s initiative took place in mid-October at the Resolution Circle of the University of Johannesburg’s Doornfontein campus, a technical training facility designed to address the skills required in the rapidly developing technical environment.

The competition saw 63 pupils, who came out tops in the previous provincial rounds held in the Free State, Gauteng, the Western Cape, Limpopo and Mpumalanga, compete against each other in five specialisations, namely welding, construction, power systems, plumbing and woodwork.

The competition aligns with SA’s National Development Plan by contributing to the target of producing 30 000 artisans annually.

Addressing the skills shortage in artisanal trades is vital for economic growth and job creation.

The competition has evolved significantly since its inception in 2018, when it was restricted to pupils in the Free State focused on welding.

Its eventual inclusion of multiple specialisations reflects the diversity of vocational skills in demand.

In 2022, the Sasol Foundation – in partnership with the Kagiso Trust – introduced the teacher component, recognising the crucial role educators play in skills development. This year, 36 teachers

RISING STARS SHINE BRIGHTLY who were provincial winners competed against each other in the welding, power systems and construction categories.

The competition provides participants with opportunities to demonstrate their talents in specific vocational skills through tasks derived from real-life, industry-based scenarios which are relevant to the needs of the job market or entrepreneurship.

Winners in each category were awarded certificates, along with state-of-the-art tools and gadgets to help them on their vocational journey.

“For sustainable development to occur, there’s an urgent need for us to pay significant attention to training highly skilled human resources to serve as key drivers of the economy. Skills competitions not only raise professional standards, but raise awareness of the potential

of skilled careers to a much wider audience,” says Noxolo Kahlana, head of the Sasol Foundation.

The competition aims to ignite a passion for technical skills at a young age, inspiring pupils to pursue excellence in their chosen vocations. It has the potential to develop the skills of more than 10 000 participating pupils and their teachers.

Sasol itself will also benefit from a skilled youth in its fence-line communities, who can participate in shutdown processes and other technical community projects, thus further benefiting the communities in which the organisation operates.

The Kagiso Trust, on the other hand, will derive benefits for its many programmes advocating for access to in-demand skills.

The competition also seeks to prepare a talented pipeline of

QUESTIONABLE BOARD APPOINTMENTS A slew of recent media reports indicate that the Johannesburg Property Company (JPC) has appointed several individuals to its board who, on the face of it, do not possess the necessary skills to govern a significant municipal entity with a property portfolio worth an estimated R8,7 billion.

These appointments, which are reported to include a receptionist, a cashier and a person without matric, appear to have been made unilaterally by the MMC for Economic Development.

“The JPC manages 30 000 properties, many of which have reportedly been hijacked. In fact, the devastating Albert Street fire that claimed 77 lives was apparently one of them. The company’s board bears ultimate oversight accountability for the inadequate management of its valuable property portfolio and it’s no stretch of the imagination to assume that the possible lack of skills lies at the heart of the problem,” says Prof Parmi Natesan,

candidates should be followed, says Natesan.

“Media reports also suggest that the MMC treats the company as a private fiefdom to which political cadres are appointed, based presumably on their loyalty and political importance, rather than their skills as directors. The sad state of municipal entities across the city – and, indeed, the country – shows the devastating consequences of flouting robust nomination processes for board and senior executive positions.”

“Without such a nomination process, board members can hardly act competently and independently in order to fulfil their legal duties, which are to the company and not to whoever appointed them,” she adds.

“These directors can be held personally liable for any untoward decisions they make. They need not only business and sector skills and experience, but also finelyhoned governance expertise.”

The IoDSA repeatedly pointed out that public-sector entities face particular challenges when it comes to appointing competent boards. The state, as the sole shareholder, has not been seen to follow best practice in this regard.

According to King IV, directors should have the correct mix of skills and experience to discharge their legal duties. A robust and transparent nomination process that includes in-depth vetting of

The performance of local government generally, including municipal entities like the JPC, has a direct bearing on service delivery and thus on the most vulnerable sectors of society.

In his keynote address on the second day of the Ninth Unesco Africa Engineering Week (AEW) and the Seventh Africa Engineering Conference, Dr Kgosientsho Ramokgopa, Minister in the Presidency for Electricity, called for a more pan-African view of energy infrastructure on the continent.

“In developing infrastructure, engineers are central to the resolution of issues of perineal under-funding and policy missteps over time, resulting in South Africa being plunged into darkness.

Other African countries then learn from our mistakes,” he said.

“We require a collective approach for Africa to achieve its potential.

Our region isn’t energy-secure and to achieve this, we need to systematically undermine sovereign borders. Electrical infrastructure is important in driving growth and prosperity. Within SA, Eskom lacks the resources, so we need to take advantage of privatesector liquidity.

“Chronic under-investment in infrastructure is preventing African producers from ramping up production to meet global demand. Currently, half a billion people around the continent don’t have access to electricity. Regional integration will ensure that we become energy-secure. As long as we’re disjointed, we’ll be superexploited!” he warned.

“In every crisis, there is opportunity which can only be seen by engineers, so we’re looking to you, as engineers, to resolve this problem.”

SEEKING A PAN-AFRICAN VIEW OF ENERGY INFRASTRUCTURE Prof Elizabeth Taylor, chairperson of the International Engineering Alliance (IEA) Governing Group, informed the audience that the entity focused on engineering mobility beyond jurisdictional borders by promoting mobility and inclusivity.

“Active engagement by all results in rich outcomes. Diversity leads to greater profitability and economic growth,” she stated. “Out of 30 countries, SA and Nigeria are the only two members of the IEA on the African continent.”

Themed “Celebrating Engineering Excellence in the African Region”, the annual event – which took place from 25-28 September, hosted by the Engineering Council of SA – celebrates and fosters engineering excellence on the continent. It also seeks to inspire and educate the youth and the public on engineering

and the crucial role of the sector in addressing Africa’s challenges. The event draws on the collaborative efforts of Unesco, the World Federation of Engineering Organisations and the Federation of African Engineering Organisations.

GOING THE GREEN ROUTE Schneider Electric, a leader in the digital transformation of energy management and automation, has rejoined the Green Building Council of SA (GBSA), a move that confirms the company’s commitment to promoting and enabling sustainable practices in the local building industry.

The GBSA is one of 75 members of the World Green Building Council and operates across the commercial, residential and public sectors to ensure that buildings and homes are designed, built and operated in an environmentally sustainable manner.

Schneider Electric’s membership also comes shortly after the release of a research paper titled Decarbonise the Office: Unleash the Power of Digital Solutions for Building Renovation, which explained that digital and electric solutions can cut carbon emissions in office buildings by up to 70%. The research, conducted in partnership

with environmental and consulting company WSP in Africa, also found that retrofitting buildings using a digital-first approach was the best route to decarbonisation.

“Becoming a member of the GBSA undoubtedly enhances our position and reputation as a trustworthy solution provider in the building segment.

Schneider Electric’s one of the world’s leaders in the energy management space and plays an important role in establishing a building industry which is committed to sustainable practices, enabled by digital technologies,” says Thabang Byl, buildings segment lead at Schneider Electric.

By joining the GBSA, the company also enjoys benefits such as: • Sustainability leadership, which sees Schneider Electric acting as a voice for energy management in the South African building industry.

• Access to resources – the GBSA provides exclusive access to the latest research, tools, trends and case studies in the green building industry. Schneider Electric can utilise this valuable information to refine its energy management offerings and contribute to the development of sustainable practices.

• Professional development – the GBSA offers tailored training programmes and certification courses, ensuring that Schneider Electric's employees are well-equipped to champion sustainability in their roles.

SA BUILT ENVIRONMENT A STEP CLOSER TO A NATIONAL BIM CODE The South African built environment is seeing real progress towards adopting a national standard for building information modelling (BIM), says Richard Matchett, the head of digital practice at leading consulting engineering and infrastructure advisory firm Zutari. “It’s being done by the book. The estimates are that in 18-24 months, we’ll have a policy ready for gazetting. However, that depends on many factors aligning.”

Matchett co-hosted the inaugural BIM CODESA on 13 July this year, an industry-wide workshop organised by the BIM Community Africa (BCA).

“Industry’s blaming the lack of a national standard for the lack of BIM adoption. In truth, it is a stumbling block. Without a standard, everyone does whatever they think is good. The really great aspect of the BIM CODESA was how we’re starting to see some real movement towards getting a standard in place,” he says.

The BCA advocates that BIM holds tremendous potential to boost delivery during all project phases to benefit stakeholders and, ultimately, the end users of those built assets. The required skills, processes and technologies are widely used in SA. However, while the industry is ready for wholesale adoption of this transforming approach to development, it lacks a national policy to create an enabling environment for all stakeholders.

The Construction Industry Development Board (CIDB) has commenced work to develop a national BIM policy for South Africa, which it aims to have gazetted by the end of 2025. The development of the policy will be supported by the BCA’s network of stakeholders, thereby broadening the source of contributions from interested parties in the built environment.

Matchett says the BIM CODESA workshop focused on the key drivers behind the process, which are the different role-players in the built environment, combined with the legal and political framework, and then sought synergies to take advantage of any interconnections.

“We need to realise that it isn’t just an engineering or an architectural point of view. Everyone in the built environment will be impacted by this policy, so its adoption needs to consider the value that all these different parties can derive from it and, in turn, bring to the table,” explains Matchett.

The ongoing process is likely to be influenced by legislation and economics, resulting in both a systems and a value chain perspective. “The built environment includes the client, quantity surveyor, architect, engineer, project manager and a host of other players. The question is: if we look ahead to a scenario where BIM’s actually adopted and is running full tilt, what will change about the way we work?” asks Matchett.

training, skills development and accreditation, and how adopting BIM will bring about the need for a different skills set in the industry.”

in this process and how the industry’s driving awareness. The conversation’s been democratised as much as possible, so it isn’t just a few isolated parties who stand to benefit. We’re also aiming to ensure that the entry barrier’s lowered in terms of focusing on information requirements, rather than software type, so that it’s cost-effective and scalable for all players,” says Matchett.

Regarding the impact of accelerating advances in artificial intelligence (AI) on BIM, Matchett predicts that it will introduce the widespread systemisation of good-quality data. “Goodquality, structured data is the entry point for the meaningful integration of AI into any process.

The BIM approach to project delivery facilitates the creation of consistent, organised data about build assets,” he says.

As for current progress in SA on the BIM front, Matchett says that while there are pockets of excellence, some remain hesitant about its large-scale adoption.

However, Autodesk recently reported that the country is actually not lagging far behind the rest of the world in this respect.

He adds that another key stakeholder is higher education and training. “We’re having a conversation about curricula,

THE MIND OF THE SAFETY LEADER

By Lani van der Merwe, senior consultant: OIM Consulting (Right): Lani van der Merwe, senior consultant: OIM Consulting.

While good safety leaders do not necessarily have to occupy management or senior leadership roles – they could be foremen, superintendents or even more experienced workers – they should still embody the qualities of a good leader if they are to be effective.

WHAT IS A SAFETY LEADER? A safety leader can be anyone in an organisation who consistently exhibits personal safety behaviours and inspires others to do the same. They may not be tasked with ensuring compliance, but naturally gravitate towards that role.

A safety leader differs from a safety manager in that the latter typically acts in an official capacity. While both are invested in organisational safety and thus influential in their own right, a safety manager or officer primarily ensures compliance with rules, regulations and occupational safety, health and environmental protocols.

A safety leader, on the other hand, will actively promote a safety culture, inspiring others to do the same.

They ensure that the value of safety is engrained within the organisation,

“SAFETY LEADERS TYPICALLY WORK IN AN ORDERLY AND STRUCTURED MANNER, ARE NOT EASILY DISTRACTED AND REMAIN CALM AND CONTROLLED IN HIGH-PRESSURE SITUATIONS.”

NOVEMBER 2023 SOUTH AFRICAN BUILDER

proactively identifying ways of improving the working environment and coaching team members in a caring way – before an incident occurs.

They constructively coach others when they see risky behaviour. Instead of assigning blame when procedures are not followed, they act to create buy-in to the underlying reason or mindset behind those procedures.

Safety leaders embody the values of an organisation, keeping safety at the centre of everything they do and championing the right behaviours. They look out for their peers and thus lead by example.

HOW DO YOU IDENTIFY A SAFETY LEADER? Start by looking for those who are already highly compliant with safety procedures and have natural leadership qualities. Safety leaders typically work in an orderly and structured manner, are not easily distracted and remain calm and controlled in high-pressure situations. They also tend to only be comfortable taking predictable, calculated risks.

They foster employee participation by encouraging behaviours that contribute towards an environment

17

HEALTH AND SAFETY

which is conducive to safety. They take responsibility for their own safety, as well as that of others.

They are flexible and adaptable when it comes to changing their behaviour and believe in working collaboratively towards goals.

SAFETY “COPS” VS SAFETY LEADERS A safety leader promotes an environment in which employees feel psychologically safe, meaning that they feel comfortable speaking up and voicing their concerns. A safety cop, on the other hand, is more concerned with policing behaviour, penalising workers who do not comply.

A safety copy is focused on identifying individuals who break rules, pouncing on infractions and assigning blame when things go wrong, whereas a safety leader encourages a culture where workers look out for one other, calmly explaining how to perform a function in a way that creates consensus.

And whereas a safety cop will usually get involved after an accident occurs, the approach of a safety leader is more proactive, seeking to avoid or mitigate potential incidents before they occur.

HOW TO PROMOTE THE DEVELOPMENT OF SAFETY LEADERS When a company has a strong safety culture, employees are active participants and are highly committed to creating a safe working environment. One of my mentors is a retired senior safety, health and environmental manager who worked in mining for over 40 years. He believes that the vast majority of mining fatalities could be avoided if workers coached one another – in a calm, engaging way – to correctly identify hazards and changes in the environment.

While organisations – especially those in mining – invest a lot of money in safety, much of this is focused on the technical aspects,

rather than on the training and development of essential safety leadership competencies and providing the necessary resources to employees.

At OIM Consulting, we offer a Safety Mindset programme rooted in on-the-ground coaching. This coaching component is critical, as our research and experience show that coaching is one of the most effective tools for sustainable, observable mindset and behavioural change.

The programme includes three to five days of theory, as well as a 12to 16-week coaching component that aims to entrench a safety mindset and practices. We also present a sustainability framework to help organisational leaders ensure that these practices become embedded in the workforce.

The purpose of the programme is to empower workers with the necessary skills sets, tool sets and mindsets to become safety leaders and thus create a strong, healthy safety culture. As writer Steven Covey once observed: “Leadership is a choice – not a position.”

MAGNETIC FLUX LEAKAGE TECHNOLOGY FOR WIREROPE INSPECTION Technology that helps give a more accurate assessment of the state of wire ropes without damaging the ropes in the process are a boon for inspectors and companies using this type of equipment.

Regular inspection of wire ropes is critical to avoid catastrophic failure and potential harm. Traditionally, inspectors have to inspect wire ropes using “destructive” testing, where a portion of the rope is unwound or counter-twisted to allow visibility of its interior.

However, in recent decades there has been significant development in the area of magnetic flux leakage (MFL) technology.

Colin Ford, MD of Lubrication Engineers (LE) SA, explains that the technology uses magnetic fields and complex computerised systems to determine the state of a wire rope, right from the centre of the strands to the outer layers of the rope.

“SA’s been involved in the development of the computer systems used for MFL since the 1980s, so it’s fitting that this technology’s now being more widely used in the country,” he says.

LE is the southern African agent for the TST FDSys.P Flaw Detection System, a portable steel-wire-rope

(Below): MFL technology detects flaws in wire ropes quickly and accurately, enhancing safety.

inspection solution that enables 100% accurate non-destructive inspection of wire ropes with diameters ranging from 6-70mm.

The TST Portable Wire Rope Tester provides instant, real-time, portable detection of wire rope flaws and is ideal for inspecting wire ropes in applications like mine hoisters, cranes, elevators, cableways, power grids, suspended bridges and drilling platforms.

HOW IT WORKS The TST Portable Wire Rope Tester uses magnetic inductive sensing technology and MFL wire rope inspection techniques. Fault events leave a magnetic signature, which the detector can pick up. This allows for high-speed, accurate and user-friendly inspections.

The tester can inspect upwards of 5m/s (or as limited for safe operation). It offers >90% repeatability of quantitative detection for flaws and 100% accuracy of severe flaw signals.

Ford explains that the four key things which need to be monitored in wire rope inspections are corrosion, fatigue, abrasion and broken wires. Tools like the TST tester can pick up both internal and external flaws to ensure that all of these four aspects are thoroughly assessed.

ADVANTAGES OF MFL TESTERS Ford says that these wire rope testers are not meant to replace the essential role that inspectors play, but to help them do their jobs more effectively.

“One of the testers’ advantages is their portability. They can be moved from site to site as necessary, or, in instances where there needs to be constant monitoring of a rope, units can be installed for continual inspection,” he says. Their compact size and portability also enable them to be used in spots that might otherwise be difficult to reach or monitor. In addition, they can be used for any length of rope, which makes them versatile.

Although most MFL testers require capital expenditure upfront, they can contribute to overall cost-savings over time. “Around 70% of wire ropes are discarded prematurely because their true state hasn’t been accurately assessed. Using MFL technology can have huge environmental and economic benefits for the industries where wire ropes are used,” says Ford.

In addition to regular inspections, effective wire rope maintenance requires that the right type of lubrication be applied in the right quantities, and at the correct intervals, to extend their lifespans.

“SA’S BEEN INVOLVED IN THE DEVELOPMENT OF THE COMPUTER SYSTEMS USED FOR MFL SINCE THE 1980S, SO IT’S FITTING THAT THIS TECHNOLOGY’S NOW BEING MORE WIDELY USED IN THE COUNTRY.”

SAICE’S SOLUTION TO CONSTRAINED FISCUS The SA Institution of Civil Engineering (SAICE) suggests an alternative solution that will assist the National Treasury as it grapples with the country’s constrained fiscus. In a letter sent to the treasury’s director-general, the institution has proposed a publicprivate partnership (PPP) solution, where the advisory fees for transaction advisors can be funded through a bridging loan from a bank, where the loan is repaid on financial close of the project taken from project funding.

This would enable continued investment in the development of infrastructure needed to boost the economy of the country, creating both jobs and enabling skills development.

It is well known that PPPs can be used to develop serviced infrastructure using private-sector capital for construction. The process is well established in SA, supported by the PPP unit of the Government Technical Advisory Centre (GTAC) within the National Treasury and regulated by the Treasury's Budget Office.

“This concept, still in its initial development and testing phase, proposes that a bank, either the Development Bank of Southern Africa or a commercial bank, funds the advisor fees by means of a bridging loan for the planning

NOVEMBER 2023 SOUTH AFRICAN BUILDER

and procurement phase of the project. The bank loan would be repaid in a single tranche, on first draw-down, when the private party achieves financial close. This would make the loan a relatively short-term one – generally about 24 months – to provide the bridging funding required to meet the transaction advisor fees,” says SAICE president Steven Kaplan.

The advantage of such an arrangement would be that the bank provides funding on a project finance-type basis to pay the advisors, with draw-downs linked to the transaction advisor achieving determined milestones.

In this way, the institution would not be required to fund the advisory fees from what is, or may become, an extremely constrained operating budget.

“The outcome would be that state institutions could enter into the planning, procurement and construction of infrastructure through PPPs without impacting their operating or capital expenditure budgets,” adds Kaplan.

A side benefit would be that government would need to be

rigorous in managing the planning and procurement process, not delaying it or cancelling the project once it has commenced. Lenders’ due diligence over the transaction advisor’s deliverables, against milestones, would help prevent corruption in the procurement process. The National Treasury Budget Office would also need to provide treasury approvals within a reasonably consistent timeline, so as not to impact the interest cost of the bridging loan.

The details of this concept are by no means finalised and the SAICE has proposed that a PPP specialist working group be formed by the National Treasury GTAC PPP unit in collaboration with the institute to workshop the mechanisms involved.

In addition to this proposal, the SAICE continues to offer to assist government in areas such as skills development through mentoring, measures to ensure the effective use of resources allocated to maintenance that will create jobs and improve skills, suggestions on reforms aimed at reducing regulatory barriers, and processes to ensure the effective utilisation of funds allocated to state entities focused on economic infrastructure.

SKILLS AND TRAINING

Cement & Concrete SA’s School of Concrete Technology will present one of its most important training courses for experienced construction personnel in November.

The SCT30 “Concrete Technology” five-day course, which includes laboratory sessions, will be offered in Midrand from 13-17 November and in Cape Town from 20-24 November.

John Roxburgh, technical specialist for CCSA and senior lecturer at the School of Concrete Technology, says this intensive course – which earns CPD points – is aimed at civil and structural engineers, experienced technicians and technologists, and is an excellent medium for gaining detailed knowledge of how cement and concrete work. The course is also recommended for electrical, mechanical and mining engineers striving to meet their mining qualification requirements.

“There’s an urgent need for engineers and experienced construction staff to have a greater knowledge of concrete technology. Sadly, however, there also seems to be an alarming sense of professional apathy about the

VITAL CONCRETE TRAINING FOR CONSTRUCTION PERSONNEL qualities of the most abundantly used construction material in the world. Civil and structural engineers inevitably have to specify, design or deal with concrete building as part of their work and, as sustainability has become the watchword globally, they need to have indepth knowledge of concrete technology,” says Roxburgh.

The SCT30 “Concrete Technology” course deals with subjects such as:

• Properties of concrete at various stages.

• Mix design and mixes for specialised applications.

• Cement and cementitious aggregates, extenders and admixtures.

• Concrete mix design, production, curing, transport and protection.

• Formwork and reinforcement.

• Sand-cement mixes.

• Concrete joints, defects, repairs, placing and compaction.

• Temperature’s effect on concrete.

• Off-shutter and architectural finishes.

“DOING MORE WITH LESS” ON N3 PROJECT

To keep up with the massive aggregates demand for the N3 national road upgrade project, AfriSam’s Umlaas Road quarry has doubled its volumes using existing resources.

The lean team on site is living up to its “do more with less” mantra.

(Above): AfriSam’s Umlaas quarry has focused its efforts on the “blue” material.

Located right on the doorstep of the very first package of the project – the 6km stretch between the Dardanellas interchange and the Lynnfield Park interchange – the Umlaas Road quarry is playing a key role in keeping this vital national project ticking.

The magnitude of the project has placed severe pressure on local construction material suppliers in the area. To provide context, it required 300 000 tons of fill material per month for the past two years.

However, recent months have seen the demand scale tilting in favour of the “blue” material, confirms Theolan Govender, regional manager overseeing the quarry.

From the onset, the team there has focused its efforts on the “blue” material, with AfriSam’s Pietermaritzburg quarry, some 30km away, providing the necessary back-up with the supply of sub-base material, including G2, G4 and G6.

“Due to the sheer scale of the project, we had to more than double our pre-Covid-19 volumes in 2021, maintaining the same feat in 2022,” says Govender. “A key talking point is our ability to push these massive volumes using the existing resources, thus transforming this small quarry into a big operation using a very lean team.”

To achieve this feat, AfriSam mobilised two existing trains of mobile crushers and screens (comprising eight machines in total) to complement the static plant.

The warehouse extension involved the creation of a new 1 000m2 mezzanine floor above the existing warehouse space, which meant raising the roof to create a total storage and manufacturing space of 3 600m2. “The client’s manufacturing operations involved the strategic placement of machines, which necessitated the roof support beams allowing an uninterrupted span of 11,9m, utilised with a 765mm precast beam.

Visser adds that the speed of construction astonished both the client and the owners of the neighbouring building. “One day there was nothing, the next there was a complete structure!

“Reducing construction time from a likely 45 days to just five gave the client substantial cost-savings, as expanded production facilities could start producing much earlier than originally envisaged.

RETAILABILITY HAILS REBUILD AT CORNUBIA LOGISTICS PARK South African retail group Retailability has described the recent reconstruction of its 13 000m² apparel distribution centre at the Cornubia Ridge Logistics Park north of Durban as a “massive collaboration” and a “good news story” for the regional economy.

The retail brand, which includes Edgars, Legit, Swagga Style and

Keedo, was just one of the hundreds of businesses that suffered considerable losses during the July 2021 violent unrest in the country.

It is estimated that at least R50 billion was wiped from the economy, two million people lost their jobs and 350 people were killed during the rioting and looting which lasted more than a week, mainly in KwaZulu-Natal.

Steve Pearson, Retailability’s head of supply chain, says the opening of the reconstructed distribution centre this month was not only ahead of schedule, but was key to allowing the business to prepare for peak season trading.

“In May 2021, we moved into our newly built distribution centre at the Cornubia Ridge Logistics Park. On 12 July 2021, the centre

was compromised due to the fires that took place in the area, resulting in another unforeseen relocation outside of the Cornubia area. Now, almost two years later, we’re back and geared for growth. That speaks to our resilience and extraordinary teamwork by our landlord and the stakeholders,” he says.

Pearson likens business operations since the disaster to “open-heart surgery while keeping the blood supply flowing”. “In a situation such as this, there are two choices: you either roll over and give up, or you get up, dust yourself off and put your shoulder to the wheel.

We managed to supply our 600 stores across the subcontinent during the unexpected relocation to temporary premises that we’d occupied for the two years since the unrest. For a retailer of our size to move and set up a distribution centre while guaranteeing stock flows without disruption takes a significant team effort and relentless commitment,” he says.

Pearson lists landlord Fortress Real Estate Investments Ltd and contractors such as construction

“FOR A RETAILER OF OUR SIZE TO MOVE AND SET UP A DISTRIBUTION CENTRE WHILE GUARANTEEING STOCK FLOWS WITHOUT DISRUPTION TAKES A SIGNIFICANT TEAM EFFORT AND RELENTLESS COMMITMENT.” firm Abbydale, conveyor and racking provider Conveyall and transport firm City Logistics as those who made it possible to complete and deliver the new premises ahead of schedule.

Jason Cooper, head of developments for Fortress, says co-ordination between eThekwini city officials, their professional team and the contractor, Abbydale, was instrumental in completing the project on very tight timelines.

He also acknowledges the commitment of sub-contractors such as Chimera Fire Protection Consultants, Specifire Protection Systems, cabling company Alltel and electrical contractor Polo Electrical.

Brian Venter, MD of City Logistics, says the goal from the start was to ensure that Retailability could continue trading through a very difficult time. “We made sure we had the required resources available to move equipment and stock over to the temporary facility. We view our clients as our business partners, so it’s our responsibility to pull out all the stops when needed,” he adds.

Conveyall was commissioned in 2021 to design, manufacture, install and commission the material handling system for the new distribution centre. However, during the riots many of the new

NOVEMBER 2023 SOUTH AFRICAN BUILDER

conveyors, electrical supply and control systems were destroyed.

Bruce Jamieson, owner of Conveyall, says they managed to get the temporary distribution centre up and running within weeks, using some of the salvaged equipment and receiving conveyors.

“Retailability was at least getting product in and out of its stores,” he says.

Jamieson says that what followed were late nights and seven-day working weeks for the crews and factory staff. “Within a recordbreaking three months, we were able to hand over another completed turnkey distribution warehouse facility to Retailability so that it could continue its distribution operations from the temporary premises.”

Conveyall designed a brandnew layout for the newly opened premises at the Cornubia business park, which was all manufactured at the company’s Jacobs factory.

“All these companies would have signed contracts for the work, but their teams went way above and beyond what was on paper. What we have now is a fully automated, state-of-the art apparel distribution facility that will serve our needs and more for the next 10 years,” says Pearson.

MONITORING TEMPERATURES DURING METAL CASTING During metal casting, the liquid material is poured into a mould, which then becomes a solid body.

However, casting temperatures which are either too high or too low can lead to quality defects.

If the temperature of the liquid metal is too low, it may cool down too quickly in the mould and stop melting. As a result, it is partially filled. If the temperature is too hot, it promotes gas porosity in the cast part and also delays the solidification process. This can lead to grain coarsening in the microstructure. Temperature monitoring of the liquid casting material is therefore indispensable for quality assurance.

NOVEMBER 2023 SOUTH AFRICAN BUILDER

ENTER THE OPTRIS SOLUTION Instrotech, a local Optris representative, offers infra-red cameras that constantly monitor the temperature of the liquid metal and that of the mould so that the quality-critical cooling phase can be influenced.

The compact thermal imaging camera Optris PI 05M is primarily used for this purpose. Due to the spectral range and continuous measuring range from 9002 450°C, it is especially suitable for the temperature measurement of molten metals.

The Optris PI 5M resolution specifications are 764 × 480 pixels @ 32Hz, 382 × 288 pixels @ 80Hz and 72 × 56 pixels @ 1kHz. The thermal sensitivity is <2K (<1 400°C) and <4K (< 2 100°C).

The temperature range is 9002 450°C, while the spectral range is 500-540nm and the ambient temperature is 0-50°C. The camera’s system accuracy

(at an ambient temperature of 23 ±5°C) is approximately 1% of measured value for 27/32/80Hz for object temperatures of < 2 000°C. The degree of protection provided is IP67.

The PI 05M and PI 1M infra-red cameras have been designed explicitly for metal industry applications. The short-wavelength PI 05M is ideal for measuring molten metals in the casting process, as the new spectral range of 500nm provides more accurate measurement with changing emissivity and is less sensitive to atmospheric influences. The Optris PI 1M is mainly used in metal processing, for example in temperature monitoring during hardening, forming and welding of metals.

POWER QUALITY AT THE SERVICE PANEL Voltage sags, tripping breakers, overheated electrical panels and excessive voltage levels indicate possible trouble in an electrical distribution system – but finding the source of the problem can be difficult and time-consuming.

Certain problems can be detected by a quick visual inspection of the electrical service panel, but others require measurements to be taken.

TROUBLE-SHOOTING STEP BY STEP Depending on the voltage and measurement requirements, various tools for power quality trouble-shooting can be used,

32

from digital multimeters to hand-held single- and threephase power quality analysers that perform many calculations automatically.

• Voltage level and stability The first step in checking to see whether voltage levels and stability are the culprits is measuring voltage levels of the branch circuits, phase-toneutral, at the load side of the branch circuit breakers.

Note: For safety’s sake, when making voltage measurements, always keep a circuit-breaker between yourself and the fault current ampacity of the feeders.

If voltage levels are low at the breaker, they will be even lower at the receptacle. This could be caused by low tap settings at the transformer. Other likely culprits include loose connections, long feeder runs and overloaded transformers, which create excessively high source impedance (impedance from the load to the source). Source impedance and voltage drop are two sides of the same coin.

If intermittent voltage sags are suspected, start at the panel to isolate the cause of sags. Are (Above): Finding the cause of the problem with Fluke Power Quality measurements.

the sags the result of loads on the same branch circuit, or are they caused by loads elsewhere in the distribution system (including utility-generated sags)? Start isolating the sag’s source with a multi-channel recording instrument, such as a Fluke power quality analyser, that can trend voltage and current simultaneously.

UPSTREAM, DOWNSTREAM • If a voltage sag occurs simultaneously with a current surge, the sag is caused by a load on the branch circuit.

In other words, the cause of the sag was downstream of the measurement point and can therefore be thought of as a load-related disturbance.

• However, if the voltage sag coincides with a very small change in current, the sag was likely caused by something upstream of the measurement point and can be thought of as a source-related disturbance.

Typical source-related disturbances are heavily loaded three-phase motors started across the line or sags originating on the utility feed.

If the sag is deep and approaches an outage, the cause is more likely to be the utility. The event probably reflects a fault and breaker trip, followed by automatic breaker reclosure.

circuit. When making these measurements, it is crucial to use a true-RMS clamp or true-RMS digital multimeter with a clamp-on accessory. An average responding clamp-on meter will not provide an accurate measurement, as the combination of fundamental and harmonic current makes this a distorted waveform. A lower-cost average-sensing meter will tend to read low, leading you to assume that the circuits are more lightly loaded than they are.

HARMONICS To check for the presence and level of harmonics, measure the current on the feeder neutral.

This will typically be in the 80130% range of the feeder current because the third harmonic will add up in the neutral.

Although most of us know that third harmonic currents (also called triple or zero sequences) generated by non-linear, singlephase loads add up in the neutral, we often wonder why.

GROUNDING Neutral ground bonds in subpanels are a violation of recommended safety measures, as well as of power quality performance wiring, but they are also quite common.

Neutral ground bonds should be made at the transformer (although they can also be made at the main panel). They should never be made downstream of the main panel, either at a subpanel or a receptacle, because then the ground path becomes a parallel return path for normal load current, resulting in measurable current on the ground.

HOT SPOTS Poor connections and the resulting heat losses are the single most significant source of system inefficiency. From a power quality point of view, loose terminations contribute significantly to excessive source impedance. Fortunately, they are easy to locate with a simple infra-red thermometer.

Infra-red measurements with tools like the Fluke 60 Series are a safe and effective technique for the non-contact detection of panel hot spots. However, it is essential to understand certain key concepts when making these measurements.

CIRCUIT-BREAKERS Many people think of breakers as having finite lifetimes. In reality, contacts and springs wear out.

Measurements of circuit-breaker voltage drop can help determine the condition of the breaker.

Measure across the line-to-load side of the branch-breaker. If the voltage drop exceeds 100mV, the breaker should be replaced.

Readings should be documented and trended in the 35-100mV range.

In summary, the service panel is the crossroads of the building's electrical system, where an experienced electrical troubleshooter can start down the right path to locate and fix any problems.

NIKKI HARD HATS: 15 YEARS’ HERITAGE IN SA’S TOUGHEST INDUSTRIES The BBF Safety Group’s Nikki brand of hard hats has played a leading role in keeping the country’s construction workforces safe, particularly in harsh mining environments.

“It’s one of the hardest-performing hard hats on the market today and has established a name for itself in terms of providing the best balance of performance and quality at great value,” says the group’s marketing manager Deane Nothard.

specified throughout a number of industries,” adds Nothard.

The Nikki 1 is also one of the few hard hats to be made from 100% virgin ABS for significantly higher durability and strength. This makes it a premium choice for particularly arduous applications, but at a mid-level price point that continues to boost its popularity.

Two shell types are available, known respectively as Nikki I and Nikki II. “Nikki’s been very successful over the years, working with customers and developing for South African environments,” says Nothard. Nikki’s acceptance and proven performance in the mining industry, the backbone of the country’s industrial economy, is testament to how entrenched the product is in the local market.

“Nikki’s definitely one of the heaviest-duty hard hats available, especially since it’s

The Nikki II is equally uncompromising on quality, using only virgin polypropylene. Both the shell types have a unique bridged construction, providing the best side-impact protection on the market.

Such is the acceptance of the product that once specified, clients seldom opt for alternative products. To ensure consistency

and quality, the BBF Safety Group recently invested in new moulds, further mould refurbishments and testing equipment.

“These investments are critical to maintain Nikki’s status in the market and ensure its continued longevity. Unfortunately, some of these upgrades caused some production downtime earlier this year, but our production’s running flat-out again and our warehouse is well-stocked,” says Nothard.

The strong heritage of Nikki is due to its consistent performance over the years, together with the BBF Safety Group using 100% virgin materials and investing in local research and development for local environments and in-house testing to ensure compliance.

“There’s sometimes confusion in the market when we hear of hard hats having been supplied as ‘Nikki equivalents’. Nikki has a unique construction and benefits from significant investments in materials and quality testing. It isn’t a product that can easily be replaced – ask for Nikki by name,” advises Nothard.

LEROY MERLIN LAUNCHES LUXENS PRIVATE-LABEL PAINT Leroy Merlin in Johannesburg has launched Luxens, its new private paint label. Already the leading paint in Greece, Italy, Portugal and France, this locally manufactured formulation now offers a highquality, eco-friendly solution tailored to the unique preferences of the local market.

Engineered to endure SA’s challenging climatic conditions and resist fading, cracking and peeling, Luxens goes beyond aesthetics to simplify the painting process.

“During independent testing, it outperformed the national average in terms of coverage and spread rate,” adds Killian.

The range début comprises a pristine white hue suitable for both interior and exterior wall and ceiling applications. This comprehensive paint solution comprises the Luxens Plaster Primer in both water-based and solvent-based options, as well as Luxens Universal Top Coat.

“What distinguishes our product is its remarkable 10-year life expectancy, supported by an unconditional guarantee, all at a competitive price point 10% lower than major competitors,” says Fred Killian, the company’s paint category manager.

Luxens will introduce an extensive colour palette in the first quarter of 2024, as well as customisable instore colour tinting, so that homeowners can infuse their spaces with their unique creativity and imagination.

Luxens underwent a thorough quality assessment in alignment with Adeo Global standards. Its commitment to sustainability is evident through its low chemical emissions formulation, which not only ensures excellent indoor air quality, but enhances the quality of living spaces. The company’s

popular private label Dexter also offers a variety of tools and accessories to ensure the success of painting projects, significantly complementing Luxens.

Leroy Merlin has partnered with the Reproplast EPR Scheme to support the “Return the Pack” movement by establishing convenient drop-off points for used or unused paint and their plastic containers at its stores in Greenstone, Fourways, Boksburg and Little Falls. Plastics often face unwarranted criticism, yet they have a smaller environmental footprint than common packaging materials. They should be re-used, not discarded as litter or in landfills. Through responsible recycling and consumer engagement, plastics can pave the way for a more sustainable future. Unused paint will be repurposed in charitable initiatives, contributing to the company's commitment to a circular economy.

ENTREPRENEURS REDUCING CONSTRUCTION WASTE The construction industry boosts South Africa’s economy through its contribution to infrastructure development and job creation.

However, there are growing concerns about the alarming increase of waste generated by this sector.

To tackle this, pioneering construction companies like CCP Sibanye and Sema Homes have dedicated their time and resources to minimising waste and embracing eco-friendly solutions.

These innovative businesses are spearheading a movement towards a greener construction industry.

In a recent article, Forbes stated: “Construction waste is expected to reach 2,2 billion tons by 2025.

Steel and concrete alone are responsible for 10% of the world’s annual greenhouse gases.”

Through CCP Sibanye and Sema Home’s innovative practices, such as recycling building materials and producing environmentally friendly construction materials, these companies are not only reducing the overall impact on the environment, but are also reshaping the future of construction in the country.

CCP SIBANYE: CONSTRUCTING GREENER BUILDINGS This Atlantis, Western Capebased business is focused on the creation of green bricks and the manufacturing and distribution of environmentally friendly construction materials.

The business was established in 2018 and the green bricks it creates are moulded from a blend of cement and recyclable materials.

They embody the vision of the

company’s founder, Dale Simons, of offering bricks that cater to the needs of individual homes and communities.

The plastic used to manufacture green bricks is sourced from waste collected during community cleanup initiatives. “This connection resonates with many individuals, as our primary objective isn’t merely the creation of bricks, but also addressing the issue of excessive waste in our communities. By adopting this approach, we’re actively contributing to the creation of a cleaner environment.” explains Simons.

utilised. “Salvageable items find new life through refurbishments, either within the same project or in future ones,” explains the company’s founder, Happy-David Sehloho Sehloho.

He adds that Sema Homes was formed as a response to the desperate need for quality construction services in lowincome areas. “Communities often suffer from poor services, leading to recurring issues and rapid deterioration. We focus on delivering exceptional quality and the best possible service to our clients,” he says.

He adds that the endeavour is remarkable because it tackles multiple challenges simultaneously.

“Not only does it lead to cleaner communities, but it promotes sustainability. The green bricks provide housing for those in need, while creating opportunities for waste-pickers who collect plastic materials,” he says.

CCP Sibanye aspires to attract investors who share its vision.

“Our objective is to establish a partnership that goes beyond financial gains to bring about positive transformation in both communities and industries alike,” says Simons.

SEMA HOMES: REDUCING WASTE IN TOWNSHIPS Sema Homes prides itself on its commitment to a “circular economy approach”, which goes beyond traditional building methods. This construction business strongly believes in the deconstruction and repurposing of materials that can still be

Its innovative practices notably reduce its waste. Left-over materials are repurposed as construction fills, while steel structures from existing buildings find new purpose within the same project or elsewhere. Sehloho’s goal is to tackle waste generation in the construction industry. “We aim to revolutionise the industry and set a new standard for environmentally conscious construction by embracing a circular economy approach,” says Sehloho.

He believes this approach not only minimises waste, but promotes a culture of sustainability and environmental responsibility.

Located in the lively township of Soshanguve, north of Pretoria, Sema Homes helps communities with construction, renovations and maintenance services.

A SHARED VISION FOR A SUSTAINABLE FUTURE Sema Homes and CCP Sibanye may be located thousands of kilometres apart and, to a certain extent, differ in the services they offer, but what they have in common is an unwavering commitment to a sustainable construction industry.

In an era when there is a dire need for leaders in construction to step up and lead by example, Sema Homes and CCP Sibanye are at the vanguard.

“THERE’S AN URGENT NEED FOR ENGINEERS AND EXPERIENCED CONSTRUCTION STAFF TO HAVE A GREATER KNOWLEDGE OF CONCRETE TECHNOLOGY.”

FRENCH KITSCH In an imaginative blend of tradition and sheer “chutzpah”, a French patisserie in Thailand has been given cathedralesque solemnity – with a few irregular, playful and distinctly modern twists The main design concept of French Kitsch in Nakhon Ratchasima, Thailand, was developed by interpreting its name. Apart from being a specialised French patisserie, the owner’s love of French bulldogs also became a brand identity, portraying a playful, yet elegant image for the café.

This was embodied in oversized red bulldogs, one squatting with its tongue out and another on its hind legs, presenting cheeky counterparts to the stately, near-medieval ambience of the surroundings. The design aimed to enhance this image, together with the concept of “kitsch”, a form of art that champions imperfection through architectural elements and materials, under which such depictions of bulldogs would be categorised.

The project was completed earlier this year and occupies a site of 360m².

The French cathedral was taken as a primary reference to the

The oversized, imperfect arch also creates a continuous space from the full-function counter to the second floor, thus highlighting the counter and allowing it to be seen from both floors. On the second floor, voids were carved into the inverted curves, allowing sunlight to enter.

The design started from a perfect rectangular mass which was rendered imperfect by carving out irregular arches on the first level and inverted imperfect arches on the second one. On the first floor, these arches embrace visitors with their antique, yet modern look, creating

The use of textured concrete strengthened the concept of the “perfection of imperfection”, where the wall was not completely smooth, but reflected the authenticity of the material – which is beautiful in itself. Moreover, by using concrete as the main material, the furniture, decorations and LED lights of green and pink were highlighted, emphasising the brand’s colour identity and creating a strong, memorable image of the café.

Building South Africa – and its people Njombo Lucky Lekula, MD: SA Cement and Materials Division Although Lekula trained as a chemical engineer, he also holds an MBA and has undergone advanced management training from the Harvard Business School in Boston, USA. “I didn’t choose the construction industry – it chose me when I was offered a bursary by PPC Cement to complete my studies and ended up working for the organisation. Once I understood the social and economic impact of this grey powder in building our nation, I felt purpose-filled and fell in love with the industry. Being an integral part of it enables me to help ensure that we have schools, roads, hospitals and houses. It’s enormously fulfilling,” he says.

“I’m proud to have been part of the industry that delivered the Gautrain and the stadiums for the 2010 Fifa World Cup in SA, the Union Buildings, the Chris Hani Baragwanath Hospital, the Durban port and Groote Schuur Hospital.

“My current role is that of a ‘choir conductor’, guiding the team in executing their various objectives. However, I also focus on stakeholders in the organisation, from customers to government. I spend a lot of time engaging with them.”

Lekula thrives on developing young talent and says his biggest frustration is the non-responsiveness of the economy in fulfilling basic human needs of citizens. “Infrastructure provides a better quality of life and gets the wheels turning by utilising resources at our disposal. It provides jobs and activates and enables the rest of the economy.

“I encourage young people to enter the construction sector so that they can build a legacy and influence the future of our country and communities. Being in this industry is more than just a job,” he says.
