savvy thinkers smart doers together people

It has been a great privilege serving the MBSA as its president. I wish to thank the men and women who serve on the board for their unfailing support during my term of office. We shared a passion for MBSA and advocated it at various platforms.

My special thanks go to Roy Mnisi, the executive director of MBSA and staff members for all their hard work and making my job easy. I would also like to congratulate my successor, Sam Ngcongo, and wish him well in his new role. I have been reminded that I will still be around as the immediate past president for the next two years.

Looking back, it has been an exceptionally busy year. We have had to deal with a rapid succession of important events and situations, many of which are still unfolding. While it has also been an eventful and occasionally challenging period for me personally, it has also been a most rewarding experience on the whole.

Last month, I noted the appointment of Dean Macpherson as the new Minister of Public Works and Infrastructure. Our industry looks forward to working with him on his top priority, which is investing in infrastructure and turning our country into a massive construction site under the theme “Let’s Build SA”.

EDITOR' S NOTE

September is Heritage Month – and, befitting that theme, we feature an inspiring project, which is part of the annual National Arts Festival, in itself a platform which showcases South Africa’s wealth of cultural and artistic heritage. The Makhanda Project attracts community members who are going out and fixing potholed roads, clearing stormwater drains and making bricks: all essential functions in kick-starting the country’s infrastructure, as well as

Site invasions are still a thorn in the flesh. Recently, Martin Meyer, KZN’s MEC for Public Works and Infrastructure, had death threats made against him, including a bullet casing placed in his car. MBSA condemns this act in the strongest possible terms.

ON HEALTH AND SAFETY

The collapse of a building in George this year has brought into sharp focus the critical importance of competency among professional team members, contractors and health and safety professionals in the construction industry. As one of the leading national representative bodies of the construction industry, MBSA urges compliance with its regulations, particularly the Construction Regulations 2014.

As we remember the victims, survivors and all those affected by the George tragedy, let us commit to upholding these standards and ensure that such an incident never happens again. We have the power and responsibility to protect the lives of workers.

making an essential contribution to the construction industry. SAB salutes them!

Equally inspiring is the launch of the Engineering and Technology Academy by Gauteng-based consulting engineering firm MedTechEngineers to address the shortage of critical and unique skills needed in the information and communications technologies, engineering, construction and maintenance sectors. It is a positive sign of determined growth of South Africa’s critical sectors,

which affirms our belief that we are on the cusp of a huge upswing our industry (and many others).

We also feature an intriguing article about the rise of padel as a prime investment area (and, concomitantly, a recreation which is requiring the construction of courts all over the country).

As we celebrate the diversity of our country’s many peoples this Heritage Month, so we celebrate their ingenuity and resilience.

ENHANCING ECONOMIC PARTICIPATION AND UPLIFTING LIVES

The 50th National Arts Festival (NAF), held annually in Makhanda in the Eastern Cape, may have drawn to a close but, with “Shaping Together” as its theme, the organisers’ work continues – not only in preparing to host the 2025 instalment of the festival, but in terms of the ongoing upliftment programmes it oversees in the town.

The NAF is one of the strategic implementation partners of the Social Employment Fund (SEF). It is a collaboration aimed at empowerment though the creation of job opportunities. The NAF manages over 2 000 previously unemployed locals at its various projects in Makhanda, with each participant paid a stipend for this part-time work. The projects focus on community development, while

maintaining and upgrading the town infrastructure, and include clearing stormwater drains, fixing potholes, collecting litter, fixing schools, planting gardens, recycling waste and working for social change.

CREATING OPPORTUNITIES

“Participants are drawn from all areas of the community. Some even hold Master’s degrees, while

others haven’t finished school, but the commonality is employment and, more importantly, skills development. The SEF is about bringing together work that needs to be done and people who need work,” says Hilton Haakonsen, project manager of the NAF’s SEF.

COLLABORATION IS KEY

Participants are divided into groups and given various tasks, for which they are trained and paid. “We’re extremely proud of the SEF projects which are fully integrated,” says Monica Newton, CEO of the NAF. “The refuse collected is sorted, glass and plastic are recycled and re-used, while alien vegetation is chipped, turned into compost and used in our food gardens. It’s about the projects collaborating to ensure that our efforts are successful.”

Since the inception of the SEF in Makhanda two years ago, there has been a 90% reduction in litter along the river banks and garbage going to the landfill has also been reduced by over 20%. Additional successes include:

• Increased food security and nutrition through the establishment of 27 food gardens, including one home garden and a large market garden.

• Maintenance of over 27 schools and early childhood development centres.

• Greening the environment and clearing over 51ha of invasive plants.

PAVING MAKHANDA’S FUTURE – ONE BRICK AT A TIME

One of the latest projects is a factory making bricks and pavers. This began a few months ago, born of the need for building materials and finding alternative uses for recycled material. The bricks are produced using a mixture of ground recycled glass and finely chipped plastic, mixed with cement.

“We’ve tested different combinations over the past months in terms of the size of the plastic chips, crushed glass and the percentage of cement and water,” says Haakonsen. “Now, after research and development, which involved endless weighing and recording of the test phases, we’re ready to go into production and already have a few orders.”

The current production is eight blocks at a time, but the team is hoping to secure funding for a second machine to increase this. Blocks are M6 in size and the pavers are 50mm pedestrian pavers. Initial plans are to use these for pavements and to build retaining walls.

Haakonsen says the aim is to become self-sustainable from the sale of compost, bricks and pavers.

SKILLS TRANSFER

Part of the SEF programme includes life skills training, as well as teaching participants additional skills to help them

“WOMEN ENGINEERS HAVE ENHANCED MILLIONS OF LIVES AND LIVELIHOODS THROUGH THEIR WORK, OFTEN CONTENDING WITH DIVERSE OBSTACLES.”

perform better. Participation in work not only provides much-needed income through stipends, but gives people entry-level work-readiness skills and the confidence to seek job opportunities, both of which are vital for securing employment. The initiative also enhances their chances of becoming self-employed or starting an enterprise.

“Receiving a stipend for work done instils a sense of dignity and purpose. It reinforces the fact that participants are earning their livelihood through their efforts and contributions within their communities,” says Newton. “It’s been incredible watching the transformation of people who haven’t had a job for years earning their own money. They’re not only proud of the work they’re doing, but are also first-hand witnesses to the difference they’re making within the community.”

Through the NAF’s projects, participants have gone on to gain permanent employment

as team leaders, with others employed for a few days a month on a contract period.

THE ROLE OF THE SEF

The SEF is bold and ambitious, vital in addressing unemployment and helping to foster economic resilience. To date, over 117 000 people have participated in and benefitted through the SEF nationally.

Made up of 65% youth and a 70% female workforce, around 65% of the work is in rural and peri-urban areas.

“Investing in social employment isn’t just a matter of economic policy – it’s a commitment to building a more inclusive and prosperous society,” says Sivu Siwisa, social employment network campaign manager.

“It uplifts individuals in the broader community and economy through enhanced employability, economic growth, social inclusion and reduced unemployment.”

The SEF is open to additional collaboration and partnerships. Those keen to make a difference or be part of the SEF initiative should visit: www.socialemploymentfund.co.za for further information.

SKILLS AND TRAINING

MED-TECHENGINEERS LAUNCHES ACADEMY TO ADDRESS CRITICAL SKILLS SHORTAGE

Gauteng-based consulting engineering firm MedTechEngineers has officially launched the Engineering and Technology Academy to address the shortage of critical and unique skills needed in the engineering and technology sectors.

For the past 15 years, MedTechEngineers has been at the forefront of the engineering and technology sector, guided by a steadfast policy emphasising the importance of balancing fieldwork with academic rigour.

“Our track record includes the

successful execution of complex infrastructure projects across various engineering disciplines. However, we recognise that each project presents unique challenges, often necessitating specialised skills sets that are both highly technical and practical. We identified a gap in the market for training individuals to meet these specific needs, which led us to establish the Med-TechEngineers Academy,” says Dr Gift Mphefu, MD of MedTechEngineers.

The Med-TechEngineers team comprises seasoned engineers, technologists, technicians, artisans

and IT professionals actively engaged in the industry. “By leveraging this wealth of expertise, launching the Med-TechEngineers Academy was a natural progression. We aim to empower and capacitate individuals, ensuring that they’re well-equipped for the demands of the field,” notes Mphefu.

Targeting professional individuals involved in the information and communications technologies, engineering, construction and maintenance sectors, the academy will equip students with practical skills required for planning, design, construction, operation,

maintenance and decommissioning of infrastructure projects across various sectors.

Further, as South Africa continues to grapple with high unemployment rates, the academy is dedicated to the non-professional labour force which is essential in the execution of infrastructure projects. “Our goal is to develop their technical competence in line with their job profiles, as well as to ensure that these individuals receive relevant certifications that are usually the gatekeepers in many of the opportunities presented within the industry,” says Mphefu.

Students who complete courses through the Med-TechEngineers Academy will gain industry certifications crucial for career advancement and employment retention, with an emphasis on realworld applicability. “Our approach has always been about bridging the gap between theory and practice,” stresses Mphefu.

What sets the academy apart is its innovative competence development model, strategic partnerships with industry leaders and educational institutions, and training programmes and courses being designed in collaboration with experts from practitioners, manufacturers, academia and other stakeholders.

The courses on offer from the MedTechEngineers Academy include a five-day Solar PV Greencard Training course endorsed by the SA Photovoltaic Association, where candidates are trained in basic

principles of solar PV design and installations. Participants will receive a certificate after the training is completed.

“We’re also at an advanced stage of obtaining accreditation for other training programmes from the Quality Council for Trades and Occupations and the Department

of Higher Education,” says Mphefu.

All courses will be undertaken at The Innovation Hub in Pretoria. “Our partnership with The Innovation Hub made it possible to use its world-class conferencing facilities to enhance the learning experience of individuals,” he adds.

FOCUS ON THE PRIZE

There is no avoiding the fact that construction remains a male-dominated industry. In the UK, Hong Kong and Australia, the proportion of women in construction has edged up about 12%, but most countries fall under 10%. At around 11%, South Africa is actually just behind the leaders when it comes to gender parity –though, in absolute terms, there is long way to go.

The reasons for this persistent inequality are complex. Building trades used to be exclusively male and that history continues to influence what opportunities are available.

However, two remarkable women are challenging these stereotypes, determined to make a difference in this industry. And although Women’s Month has just ended, it is never too late (or inappropriate)

to celebrate them.

Both women were attracted to construction because they saw it as one of the foundational industries that determine what the economy – and country – looks like. Rose Tsenase, founder and CEO of Bashoeshoe Construction and a previous Master Builders Association North executive committee member, says: “From a young age, I was fascinated by the transformative power of construction – the ability to shape environments and communities.”

A marketer by profession and currently studying for her Master’s in HR management, Tsenase sees construction as her career. She studied at the Khuthaza construction school for women and has completed several short courses in construction. After several years in the industry,

she founded Bashoeshoe to address what she saw as a niche – innovative building technology. The country’s need for more quality affordable housing makes innovation in this area especially important, she believes.

Karabo Motsepe-Marutla, another mould-breaker, joined Corobrik in 2008 with a degree in political science from the former Rand Afrikaanse Universiteit (now the University of Johannesburg). She found the company’s culture of openness and collaboration highly attractive and is still with it, where she currently leads the government development department – and also sits on the Master Builders Association North executive committee. “A strong female presence in any industry is desirable because we bring a fresh perspective and our skills in areas like problem-solving,

teamwork and inclusivity really add value,” she says. “Better gender representation opens up the workplace to new ideas.”

Both women agree that although the construction industry continues to be characterised by traditional gender stereotypes, things are slowly changing.

“Overcoming these stereotypes isn’t easy, but one has to be persistent and accept the fact that challenges are an opportunity for learning,” says Motsepe-Marutla.

“By committing yourself to excellence and innovation, you earn respect and recognition,” adds Tsenase.

WALKING THE WORK-LIFE TIGHTROPE

A key issue for women in the workplace generally is striking a work-life balance – and construction is no exception. It is well recognised that women assume the lion’s share of domestic and childcare responsibilities, further compromising their ability to do the hard work needed to break through entrenched ways of doing things.

Tsenase says that putting in place the right strategies and support systems is vital. “It’s important for me to play my role as a mother while I pursue my goals,” she says. She believes that flexible work hours can make a huge difference in this regard.

These two women’s separate

experiences confirm what many other women who have been successful in maledominated spheres have noted: the importance of mentors. Motsepe-Marutla says her CEO, Nick Booth, is an important mentor for her, but her greatest role model remains her 92-yearold grandmother who, having lost her husband almost 50 years ago, set herself the goal of ensuring her seven children got the education they needed to succeed in life.

Tsenase believes that government needs to do more by implementing new policies and enforcing existing regulations to drive gender inclusion in the industry. Public education and advocacy are also important, both to challenge stereotypes and alert women to the opportunities which the construction industry offers.

“It’s not just about hard hats,” laughs Motsepe-Marutla. “The industry’s constantly changing and growing, so there are many areas – architecture, design, engineering, planning, health and safety, to name just a few – where female graduates can shine.”

However, these opportunities will continue to be limited by the headwinds the construction industry faces. One element is the continuing inability of government to implement its ambitious plans to build more infrastructure, while its slowness in paying is also an

ongoing challenge.

The construction mafia – “Let’s call it what it is,” says Motsepe-Marutla – is also a factor inhibiting the industry’s recovery.

Mohau Mphomela, executive director at MBA North, says that female leaders like MotsepeMarutla and Tsenase show that the construction industry is gradually changing. “Women like these are paving the way for a new generation of women to see our industry as a place where they can build satisfying careers and drive meaningful change,” he says.

The 2024 MBSA National Safety Competition saw 44 entries, with three sub-contractors recognised and three voluntary withdrawals. Audits were conducted at 42 construction sites, including plant yards and manufacturing premises, across various categories over six weeks from 18 June-31 July. During this time the two auditors travelled a total of 10 403km by road and air. The average compliance rate of the 42 audited sites was 98%, reflecting a very high compliance standard among the members.

AUDIT TEAM

The judging panel included Zenzele Mabuza, the OHS manager of MBSA and Deon Bester, the OHS manager of MBA Western Cape.

AUDIT METHODOLOGY

The audit team employed a methodology where items that

2024 MBSA NATIONAL SAFETY COMPETITION

did not apply to the site, or where specific activities or machinery/ equipment were not in use during the audit, were marked as “not applicable”.

The audit team respected the following set of objectives:

• No interrogation of the participants.

• Documentation would be accepted at face value and the judging team would not comment on it.

• The team would do random sampling of scaffolding and other equipment on site to verify documentation.

• Competitors would be treated equally and with respect.

• There would be no attempts to coach the site staff.

AUDIT SYSTEM

The MBSA Audit System, Version: 2024 [INTERACTIVE] was used during the competition. The

audit process was conducted in two phases, a site walk-about, the sampling of various items and the verification of documentation.

Hard-copy documents were required. Only in exceptional cases was electronic evidence accepted.

MBSA wishes to thank the MBA Associations, especially their OHS managers and support staff, for their knowledge and assistance. Additionally, we thank the 2024 NSC participants from various construction companies and regions, as well as Federated Mutual Assurance for being the champion of construction health and safety, and for making this initiative possible.

The winners will be announced at the MBSA Annual Congress on 6 September 2024 at the Boardwalk Hotel and Casino in Gqeberha, Eastern Cape.

The 2024 MBSA Annual Congress is just around the corner and promises to be a landmark event for the construction industry. Set against the scenic backdrop of Gqeberha, this year’s congress is not just another industry gathering; it is a crucial forum for discussing the role of construction in driving SA’s economic growth and renewal. Taking place on Friday, 6 September 2024 at the Boardwalk Hotel & Casino, the event will bring together industry leaders, policymakers and experts to explore the theme of “Building Economic Fortitude: The Crucial Role of Construction in SA’s Economic Growth and Renewal”.

DEVELOPING FUTURE LEADERS IN OCCUPATIONAL HEALTH AND SAFETY IN SA

MBA North collaborated with the University of Pretoria’s Faculty of Health Sciences to provide practical training for future occupational health and safety (OHS) practitioners. This initiative, involving MBA North’s members and their sites, aimed to expose students to real-world hazards, risks and potential occupational diseases and injuries in the industry.

The University of Pretoria’s Faculty of Health Sciences, through its School of Health System and Public Health (SHSPH), offers a post-graduate Diploma in Occupational Medicine and Health and a BSc Honours in occupational hygiene. These programmes are designed for medical doctors and scientists aspiring to advance their expertise in occupational hygiene, health, medicine and safety.

On 14 June this year, MBA North’s CHS officers, along

with members from companies such as Enza Construction at the Africa Data Centre-ADC 2.5, Archstone Construction SA at Meadowview Sites 9 & 10 New Warehouses, Tiber Construction at the ACSA building, GVK-Siya Zama Building Contractors Gauteng at the Bertrams MultiPurpose Centre and VIVA Projects JHB at Our Parents Home Project, hosted a group of 35 students and five coordinators. The students were split evenly across the mentioned sites for the day’s activities, which included.

• A briefing on the project background, work processes, anticipated hazards, risks and possible diseases and injuries.

• Site walk-throughs.

• A discussion on high-stress and demanding project hours.

• Various OHS-related topics.

This initiative was especially

meaningful, as it coincided with Youth Month in June. Youth Month highlights the importance of young individuals as change agents and provides an opportunity to address their concerns, recognising their significant role in shaping the country’s future.

The event was of great significance, given the country’s recent construction site incidents (including the collapse of the apartment building in George in May, which claimed several lives and left many others injured). The industry cannot afford tragedies like these if it is to be sustainable. Only by training a competent, accredited generation of OHS officers, who can ensure that safety measures are in place on all and any construction projects, can such disasters be avoided in the future.

MIASA JOINS CMA AS STRATEGIC PARTNER

Public- and private-sector entities across Southern Africa’s mining sector are intensifying co-operation to enhance the critical mineral value chain for economic growth. In July this year, Mozambique, Zimbabwe and Botswana signed an agreement to upgrade an existing railway line linking the three countries and to build a new line and a deep-water port in Mozambique. The transnational railway line will be crucial in transporting critical minerals – including Botswana’s copper, manganese, cobalt and nickel, Zimbabwe’s platinum and Mozambique’s graphite – to international markets.

In line with its commitment

to advancing co-operation between Southern Africa’s mining associations and stakeholders, the Mining Industry Association of Southern Africa (MIASA) has joined the Critical Minerals Africa (CMA) Summit as a strategic partner. MIASA’s participation underscores the event’s significance in driving Africa’s critical mineral industry growth by uniting regional stakeholders on policy development, technical expertise, investment and capacity-building.

The Critical Minerals Africa 2024 summit on 6-7 November serves to position Africa as the primary investment destination for critical minerals. The event is

held alongside the African Energy Week: Invest in African Energy 2024 conference) on 4-8 November, offering delegates access to the full scope of energy, mining and finance leaders in Cape Town. Sponsors, exhibitors and delegates can learn more by contacting: sales@energycapitalpower.com.

“The growing demand for clean energy technologies is increasing the demand for Southern Africa’s critical minerals. Co-operation between Southern Africa’s mining stakeholders is vital to unlock the region’s full critical mineral potential to drive the global energy transition and the growth of local economies,” says Rachelle

Kasongo, project director at CMA organiser Energy Capital & Power.

Since 1998, MIASA has fostered collaboration between the SADC mining sector and the private sector, promoting industry prosperity. Uniting Chambers of Mines from 11 countries (Botswana, the DRC, Lesotho, Madagascar, Mozambique, Malawi, Namibia, South Africa, Tanzania, Zambia and Zimbabwe), MIASA encourages best practices and creates a conducive environment for growth.

Recognising the importance of co-operation to unlock critical mineral prospects, Southern African stakeholders continue to prioritise regional partnerships. In May 2024, Cape Town investment agency Wesgro and Namibia’s Environmental Investment Fund signed an agreement to advance the development of green hydrogen infrastructure linking the Western Cape and Northern Cape regions of SA with the Lüderitz/ Windhoek region in Namibia. The project will help boost the use of SA’s platinum group metals for green hydrogen applications, enhancing local and regional energy security, decarbonisation and economic growth.

The DRC, Angola and Zambia have intensified collaboration among themselves and with global partners – including the European Union and the US government – to integrate logistics infrastructure and services as part of the Lobito Corridor for optimal transportation of critical minerals to global markets. In July 2024, the Lobito

Atlantic Railway consortium (operator of the Lobito Corridor) began operations at Angola’s Port of Lobito, receiving its first cargo vessel carrying 40 500 tons of sulphur for transportation to the DRC and Zambia for mining applications.

SA’s Department of Mineral Resources and Petroleum is also exploring critical minerals in South Sudan in partnership with the East African country’s Ministry of Mining. The partnership will strengthen South Sudan's position in the global critical mineral sector and SA’s industry expertise to advance critical minerals mining locally and throughout the SADC region.

At CMA, MIASA will provide an update on the activities of its members, highlighting investment and partnership opportunities for global investors within Southern Africa’s energy transition metals sector.

“CO-OPERATION BETWEEN SOUTHERN AFRICA’S MINING STAKEHOLDERS IS VITAL TO UNLOCK THE REGION’S FULL CRITICAL MINERAL POTENTIAL TO DRIVE THE GLOBAL ENERGY TRANSITION AND THE GROWTH OF LOCAL ECONOMIES.”

SAICE CALLS FOR EQUITABLE TENDER PRICING TO PRESERVE STANDARDS

The SA Institution of Civil Engineering (SAICE) has called for a renewed commitment to equitable tender pricing in the engineering sector to safeguard the quality and integrity of engineering projects across the country. In light of increasing pressures for some engineers to reduce their fees, the SAICE

emphasised the need for fair compensation that reflects the true value of engineering services.

SAICE CEO Sekadi PhayaneShakhane underscored the critical challenges faced by some engineers when negotiating with clients. “In some cases, engineers are expected to lower their fees,

even after adjustments have been made to align with the gazetted fees published by the Engineering Council of SA,” she explained. “This relentless push for reductions can often result in engineers compromising their rates to secure business.”

SAICE 2024 president Andrew

SAICE CEO Sekadi Phayane-Shakhane.

Clothier stressed that this practice was detrimental to the financial health of engineering firms and also raised significant ethical concerns. “Offering significantly discounted rates can undermine the profession's reputation and devalue the essential services engineers provide. It’s imperative that we restore the credibility and value of engineering work while balancing the need to secure business and upholding professional integrity,” he said.

The issue of tender pricing has been a long-standing challenge in the contracting environment, significantly impacting the industry’s dynamics and calls for a collective industry response to address these persistent challenges. To tackle this issue, Phayane-Shakhane said that collaboration with key industry stakeholders was critical. “By working together, we can advocate fair tender practices and ensure that engineering services are adequately valued,” she stated.

Further discussions to this end are being explored to find potential solutions to the current tender pricing conundrum. Clothier highlighted concerns about recent tender evaluations, which have shown a tendency to prioritise the cheapest options. “We must emphasise the importance of viewing design fees as an integral component of the final project cost. Adequate investment in the design phase can yield significant savings, enhance project feasibility and substantially mitigate risks,” he added.

The SAICE highlighted the importance of reinforcing fee guidelines and ensuring industry-wide adherence to prevent price undercutting. “Adhering to established fee guidelines is crucial for maintaining fair competition and the overall value of engineering services. This isn’t just about sustaining our businesses, but

“IN SOME CASES, ENGINEERS ARE EXPECTED TO LOWER THEIR FEES, EVEN AFTER ADJUSTMENTS HAVE BEEN MADE TO ALIGN WITH THE GAZETTED FEES PUBLISHED BY THE ENGINEERING COUNCIL OF SA.”

about preserving the integrity and safety of projects,” said Phayane-Shakhane.

She called for a united front in the engineering community to uphold these standards. “We must continue to educate our clients in the long-term benefits of investing in quality engineering services and the risks associated with opting for the lowest bids. By collectively upholding fee standards, we enhance the overall value and perception of our profession.”

Both Clothier and PhayaneShakhane reiterated the SAICE’s commitment to supporting sustainable business models for engineering firms. “Our goal is to develop strategies that balance competitive pricing with business sustainability, ensuring fair compensation for the invaluable services our engineers provide. Together, we can uphold the highest standards of our profession and contribute to the successful development of our nation's infrastructure, they said.

surrounding commercial hubs and office parks. By providing a curated mix of stores and services, we’re addressing the needs of busy professionals who seek quick, quality options close to their workplaces. This development reflects our commitment to enhancing the daily lives of those who live and work in the Waterfall area,” says O’Donnell.

The infrastructure supports uninterrupted shopping with backup water facilities, a generator, solar panels and high-speed fibre.

Easily accessible via the N1 highway, the Midrand Gautrain station and Grand Central Airport, Waterfall Walk is perfectly positioned to serve the residents of both Johannesburg and Pretoria. It is scheduled to open in April 2025.

TEAMWORK REOPENS HIGHWAY AHEAD OF SCHEDULE

The old maxim, “Many hands make light work”, certainly proved its truth when Consulting Engineers announced the successful reopening of the main N2 highway between Durban and Cape Town a month ahead of the anticipated threemonth construction schedule.

Despite several challenges, the achievement illustrated the power of commitment and teamwork.

The project, led by Zimile’s routine road maintenance manager Amit Bhoora, faced significant obstacles, including localised flooding and disruptive site conditions between

Port Shepstone and Kokstad. The collapse of an ageing drainage culvert as the result of unusually heavy rains in midJanuary resulted in the complete closure of the highway. The deluge caused a nearby farm dam to overflow, which washed away the culvert and led to

dangerous subsidence of the road surface.

“THE PROJECT, LED BY ZIMILE’S ROUTINE ROAD MAINTENANCE MANAGER AMIT BHOORA, FACED SIGNIFICANT OBSTACLES, INCLUDING LOCALISED FLOODING AND DISRUPTIVE SITE CONDITIONS BETWEEN PORT SHEPSTONE AND KOKSTAD. THE COLLAPSE OF AN AGEING DRAINAGE CULVERT AS THE RESULT OF UNUSUALLY HEAVY RAINS IN MID-JANUARY RESULTED IN THE COMPLETE CLOSURE OF THE

HIGHWAY. ”

“Zimile was appointed by the SA National Roads Agency [SANRAL] to manage this crucial project as part of its 246km routine road maintenance contract, with a target to reopen the N2 within two months – one month ahead of the usual project timeline,” says Bhoora. “Achieving SANRAL’s target date required an all-hands-on-deck approach, as we navigated significant technical, environmental and political challenges.”

Having initially considered various innovative techniques, Zimile settled on a traditional solution due to time and material constraints, as well as continuous rain. The chosen approach involved a dump rock foundation and the installation of four 1,5m-diameter concrete pipes encased in a concrete shell to manage future overflow events.

“The volume of water from the overflowed farm dam was immense. It took five days for the water to subside after we’d

excavated a drainage channel across the embankment,” says Bhoora.

The project’s contractor, VEA Road Maintenance, also faced numerous challenges, both practical and political. Multiple local and district municipalities claimed the project, leading to demands from local business forums for work opportunities. This issue was resolved by splitting the work among different communities. Continuous heavy rain further complicated the project, turning the site into a quagmire and causing vehicles to get stuck.

“Additionally, the nearest quarry supplying dump rock was 45km away and other road projects had priority on materials. Through negotiations, the quarry worked overtime and a convoy of 25 dump trucks transported the G7 material for the foundation,” explains Bhoora. “We also had to construct a secondary road to allow the heavy trucks to reach the site without getting stuck.”

Thanks to the tireless efforts of the team, the N2 was reopened to traffic on 27 March, just in time for the heavy traffic of the Easter holidays. Final ancillary work, including the completion of culvert headwalls, guard rails and road markings, continued after the roadway was opened.

“We’re proud to have delivered this essential infrastructure ahead of schedule, ensuring the safety and convenience of roadusers,” says Bhoora.

PADEL COURT INVESTMENT:

TRENDING NOW

Padel courts are popping up everywhere. What first began in Mexico in 1969 has since spread the world over – and South Africa is no exception.

As it stands, there are 40 000 padel courts globally, with the latest tally in SA sitting at around 200 courts and counting.

Since the first court was erected just five years ago at Val de Vie in Paarl, sharp demand has given rise to an increasing number of investors seeking to cash in on one of the most popular new sports in the country.

And as the craze continues, prominent players such as South African REIT Attacq Ltd are finding unique ways to reconfigure

prime commercial real estate to accommodate padel courts, like the Mall of Africa, which now boasts six padel courts.

SERVING UP SPACE

While the prospect of padel court investment is on everyone’s minds, for most, space – and the right space, at that – is of key concern.

“There’s high demand for padel courts, but the reality is that space is a limiting factor for many upcoming investors,” comments John Jack, CEO of Galetti Corporate Real Estate.

“The likes of Virgin Active, hotels around the country, prestigious golf courses and the country’s big REITs with flagship shopping centres have space earmarked

for reconfiguration. However, the biggest barrier for new investors is access to prime real estate in areas yielding high foot traffic, visibility, demand and, ultimately, high returns.”

One of the opportunities towards which investors have gravitated is the reinvention of old, dilapidated tennis courts. “Tennis courts have been revitalised into padel courts, but the opportunities are now few and far between and we, as commercial real estate brokers, are noting that there are more enquiries for padel space from investors,” says Jack.

And while there is some land available in SA for development purposes, he

John Jack, CEO of Galetti Corporate Real Estate.
“TENNIS COURTS HAVE BEEN REVITALISED INTO PADEL COURTS, BUT THE OPPORTUNITIES ARE NOW FEW AND FAR BETWEEN.”

adds that padel does have its own unique set of criteria.

WHAT MAKES A SUCCESSFUL PADEL COURT?

“Factors such as accessibility, security, general atmosphere, amenities or space for the development of amenities like restaurants, toilets, showers, saunas, kids’ play areas, etc must be considered,” he explains.

In addition, courts need to be 21 x 11m, have drainage, be north-south-facing and have ample, safe parking, according to Roger Barrow, a former Olympic rower, member of the Barrow construction family and general manager of the Padel Building Company.

Jack says that the area must be well researched prior to investment and that weather conditions cannot be overlooked. “Consider the demographic of the area, know your target audience, calculate your investment and returns, and do thorough investigations prior to investing alongside trusted experts,” he advises.

“If you’re considering an outdoor court, then you need to factor in the weather, which will limit your profitability in times of heat, wind and rain. This is particularly prevalent in rooftop set-ups, which

are proving to be quite popular at the moment.”

He adds that what continue to prove particularly popular are SA’s CBDs, as many professionals opt to play padel before or after work.

“This presents an opportunity for the office sector resurgence, particularly in Johannesburg, where the vacancy rates remain low.”

COSTS AND RETURNS

Barrow says the growing popularity of padel courts is commensurate with their cost.

“The cost of building a court is anywhere from R600 000R1 million (excluding the land) and including civils, steel erection, etc,” he says.

He adds that when it comes to investing, economies of scale do help to bring the costs down. “One of the biggest unforeseen costs is that of glass and steel. As it stands, the majority of the courts in the country are actually plug-and-play solutions from China.”

Barrow says that the return on investment varies greatly. “The early adopters of padel were able to operate at 70% capacity and pay off the court in a period of about one year. However, it

depends on the total investment; did the investor add a restaurant, what are their staff and running costs?”

One of the stumbling blocks for padel courts today is the occupancy rate. “Most courts in SA operate at a 30-50% occupancy rate. Anything over 60% requires you to fill dead hours, such as 1-3pm and any time between midnight and 5am. Most courts have their highest players from 5-8.30am and 4-10pm,” says Barrow.

For those operating at 30% occupancy (and depending on what they have invested in terms of amenities), there is a possibility that a court can be paid off over a period of about four years.

FAD OR EVERLASTING TREND?

“It’s no secret that people get bored easily,” says Jack. “Whether or not this is a sustained trend or an imminent fad remains to be seen.”

Internationally, Sweden, one of the early adopters of padel courts, has recently cited over-saturation in the market.

“While this is certainly a possibility, I believe that inventive investors are paving the way to something bigger. Very often, the courts are entrenched in beautiful areas, feature great amenities and cater for the whole family. Regardless of whether padel remains as popular as it currently is, I believe that investors who think out of the box will continue to see the biggest returns,” says Jack.

CORROSION-FREE REBAR

Concrete is the world’s most widely used construction material. Although extremely durable, its chief vulnerability is corrosion. This occurs more readily on ageing structures, but can also attack new concrete located in hot, humid seaside climates or regions that rely heavily on de-icing salts. Accordingly, rows upon rows of green epoxy-

coated rebar are often seen staged at construction sites for enhanced protection. However, it is important that engineers and contractors understand this may not be an end-all to their corrosion worries and they need to be aware of alternative methods for overcoming the deficiencies of epoxy-coated rebar.

EPOXY COATING DEFICIENCIES

If the epoxy coating on rebar remained undamaged, it would provide exceptional protection by creating a thick barrier to corrosives. Unfortunately, coating damage is all too common. As epoxy-coated rebars roll off the paint line and get bundled for shipment to jobsites, their most vulnerable stage begins.

MCI® can protect an entirely uncoated rebar or molecularly fill in damaged areas on an epoxy-coated rebar where the metal is exposed.

“When coated rebars are transported, bent, welded and installed, there’s a great probability that the coating will be physically damaged. The damaged areas will become small anodes coupled to large, coated areas which, in turn, become cathodes, causing pitting failures,” says Cortec® CEO Boris Miksic. “The question, then, is how to find a back-up technology that inhibits corrosion at these points.”

A MOLECULAR PROTECTIVE LAYER

Migrating corrosion inhibitors (MCI®) are an exciting, versatile and budgetfriendly option. Applied as an admixture or a surface treatment, MCI® chemistry works its way through concrete pores and forms a protective molecular layer on the surfaces of metal reinforcement due to an ionic attraction. It can therefore protect an entirely uncoated rebar or molecularly fill in damaged areas on an epoxy-coated rebar where the metal is exposed. MCI® is classified as a “mixed” inhibitor because this molecular layer affects both anodic and cathodic portions of the corrosion cell. MCI® can double or triple the time to corrosion initiation and significantly reduce corrosion rates, once started.

COMPARING MCI® AND EPOXY-COATED REBAR

MCI® admixtures such as MCI®-2005 (a USDA-certified

biobased product) or MCI®-2005 NS are easy to work with when added to ready-mix at the time of construction. Specifying engineers can use service life prediction modelling to estimate and compare how much MCI® is expected to extend service life in various environments versus the projected performance of epoxy-coated rebar. The differences can be significant. In one Gulf project, the MCI®-2005 service life prediction surpassed the projected service life of epoxycoated rebar, while saving the project hundreds of thousands of dollars. Although MCI® can be used as a total replacement for epoxy-coated rebar, those who want extra “insurance” and have the budget for it can specify MCI® alongside epoxy-coated rebar for complementary back-up protection in areas where the coating may be damaged.

WHAT IF THE DAMAGE IS ALREADY DONE?

Sometimes the contractor has already seen damage on the rebar coating, but it is too late to specify an MCI® admixture for a project underway. Fortunately, builders still have the option of adding an MCI® surfaceapplied corrosion inhibitor (SACI) once the structure is completed. MCI®2020 contains the highest concentration of MCI® of

INNOVATION

“WHEN COATED REBARS ARE TRANSPORTED, BENT, WELDED AND INSTALLED, THERE’S A GREAT PROBABILITY THAT THE COATING WILL BE PHYSICALLY DAMAGED. THE DAMAGED AREAS WILL BECOME SMALL ANODES COUPLED TO LARGE, COATED AREAS WHICH, IN TURN, BECOME CATHODES, CAUSING PITTING FAILURES.”

any SACI on the market and can be sprayed or rolled onto existing structures. It first moves through the concrete matrix by capillary absorption and then by vapour diffusion, gradually migrating as much as several centimetres into the concrete to reach and protect the embedded rebar.

COST BENEFITS

Epoxy-coated rebar may seem to be an attractive option, until one looks more closely at the price and potential concerns of coating damage. Since MCI® offers to extend service life at a much lower fraction of the total construction cost, engineers should carefully consider specifying MCI® as either a complement or complete replacement to epoxy-coated steel.

FLUKE FUNDAMENTALS

Whether testing switches and fuses or making general electrical connections, mastering a continuity tester is critical to effective electrical troubleshooting.

SETTING UP YOUR DIGITAL MULTIMETER

FOR CONTINUITY

TESTING

Setting up your digital multimeter properly involves:

1. Selecting the correct mode: Turn the dial to continuity test mode. This mode is often combined with other functions, typically resistance (Ω). The multimeter’s display may show OL and Ω, with the test probes separated.

2. Activating continuity mode: Some models require pressing a continuity button to activate this specific testing mode. If your multimeter has that feature, ensure this step is followed.

EXECUTING THE CONTINUITY TEST

Once your digital multimeter is set up, follow these steps to conduct the continuity test:

1. Connecting test leads: Insert the black test lead into the COM jack. Then insert the red lead into the VΩ jack. Always remove the leads in reverse order after testing: red first, then black

2. Testing the circuit : Connect the test leads across the tested component with the circuit de-energised. The position of the test leads is arbitrary, but ensure that the component is isolated from other components in the circuit.

3. Interpreting results: The digital multimeter (DMM) emits a beep if a complete path (continuity) is detected. If the circuit is open (the switch is in the OFF position), the DMM will not beep.

4. Concluding the test : When finished, always turn the multimeter OFF to conserve battery life.

UNDERSTANDING

CONTINUITY TESTING:

PRINCIPLES AND PRACTICES

Continuity is the presence of

a complete path for the current flow. A circuit is considered complete when its switch is closed. Here are some key points to remember:

• Applications of continuity testing: A digital multimeter’s continuity test mode is versatile and suitable for testing switches, fuses, electrical connections, conductors and other components. For example, a good fuse should show continuity.

• Audible indicator: The beep is an audible response from the DMM when it detects a complete path, allowing technicians to focus on the test without constantly monitoring the display.

• Understanding resistance and beeps: The beep is triggered based on the resistance of the tested component, influenced by the multimeter’s range setting. For instance, at a 400,0 Ω range setting, a multimeter typically beeps if the component has 40 Ω or less resistance.

• Optimal range setting: Use the lowest range setting to test components with low-resistance values, such as electrical connections or switch contacts.

IT’S READY-MIX TRUCK CLEAN-UP TIME!

The construction season is in full swing in many parts of the world. That means now is a good time to re-evaluate your current concrete clean-up strategy. If you find your process unsatisfactory, Cortec® invites you to add MCI® Super Remover to your clean-up routine.

Regular cleaning not only keeps equipment looking good and preserves its value, but can also keep it in better working order –especially where concrete buildup is concerned. While clean-up of concrete mixer trucks and tools is imperative, it is also challenging because the dry residue gets so hard that workers sometimes have to chisel it off.

Super Remover can cut down on the effort needed by quickly and easily removing hardened concrete residue. After allowing the cleaner to soak into the hardened concrete for a few minutes to several hours, workers can lightly scrape or pressurewash away the softened residue and then rinse the surface with a VpCI®-41x series alkaline cleaner for neutralisation. MCI® Super Remover can be used regularly to keep ready-mix trucks, pan mixers, formwork, batching plants and drum mixers clean and functional.

Although appropriate PPE should still be used, MCI® Super Remover is a safer option for

workers than muriatic acid. On the cost-savings side, it can be used multiple times, as long as the sediment is filtered out and the pH remains below 2,0. Its biodegradability and low contribution to BOD/COD in wastewater effluent make it a good alternative to phosphoric and nitric acid cleaners.

Concrete residue will not disappear by simply ignoring it. Keep your ready-mix equipment in good working condition by giving it a regular cleaning with MCI® Super Remover.

GALVANISED REBAR ENSURES RESILIENT, FUTURE-PROOF INFRASTRUCTURE

Corrosion damage to reinforced concrete structural members such as foundations, columns, retaining walls or piles poses a significant threat to structural integrity.

Galvanised rebar plays a crucial role in ensuring resilient, future-proof infrastructure in terms of effective protection against corrosion.

Even when other measures are used, such as extra concrete cover or reducing concrete permeability, galvanised rebar enhances safety and reliability.

“Addressing corrosion

during construction minimises maintenance costs and disruptions,” notes Simon Norton, director of the International Zinc Association (IZA) Africa.

The IZA reports that corrosion damage to reinforced concrete structures in the USA costs an estimated $20 billion a year. This figure is expected to grow by $500 million each year as existing infrastructure continues to age. In South Africa, ageing wastewater works, waterworks and rail infrastructure need to be repaired with galvanised rebar.

“Dealing with corrosion post-

construction is costly and disruptive, as all or part of the structure needs to be closed periodically for maintenance and repair. Failure to properly address corrosion can also lead to catastrophic structural failures, with potentially deadly consequences,” explains Norton.

Many of these costs and safety issues are avoidable if the potential for corrosion is minimised during construction through proper design and material selection. This is especially critical for the reinforcing steel and the structural steel connectors used to strengthen and join

Galvanised rebar plays a crucial role in ensuring resilient, future-proof infrastructure.

concrete sections.

Corrosion can be managed by reducing concrete permeability through optimal water and cement ratios, appropriate compaction and curing conditions, the use of concrete impregnation methods or membrane-type concrete coatings and by providing a good depth of concrete cover over the rebar.

“All of these measures can delay the corrosion of rebar, but not prevent it. The use of galvanised rebar has real benefits in improving the safety and reliability of reinforced concrete, even when the above

measures are used,” says Norton.

Galvanised zinc coatings form an impervious metallic zinc barrier around the steel to isolate the steel surface from the surrounding concrete. This barrier is the first line of defence to protect the steel from corrosion.

The excellent corrosion protection offered by zinc coatings or galvanising derives from both the low natural corrosion rate of zinc, coupled with its ability to extend protection to adjacent exposed steel areas, an effect known as cathodic protection.

The coating also exhibits strong adhesion to the underlying steel surface due to its unique metallurgical bond which, together with the inherent toughness of a metallic coating, provides superior resistance to mechanical damage. The combination of these features results in a very durable coating, enabling concrete structures to be more tolerant of variability in concrete quality and reinforcement placement.

Material specifiers and product engineers in key end-use markets such as building, construction and transportation are increasingly interested in selecting materials that have the best environmental profile while meeting traditional cost, quality and technical performance criteria.

Measuring the impact and resource requirements associated with zinc production against the impact and the benefits of using

“ALL OF THESE MEASURES CAN DELAY THE CORROSION OF REBAR, BUT NOT PREVENT IT. THE USE OF GALVANISED REBAR HAS REAL BENEFITS IN IMPROVING THE SAFETY AND RELIABILITY OF REINFORCED CONCRETE, EVEN WHEN THE ABOVE MEASURES ARE USED.”

zinc during other stages in the product life-cycle show zinc to be a very sustainable material. The environmental footprint of galvanised coatings has also been well documented, adds Norton.

“Galvanising can extend the life of steel and concrete structures to 100 years or more, enabling huge conservation of natural resources by reducing the waste inherent with premature endof-life. Energy-savings are also accrued through minimised maintenance and upkeep,” he says.

The end-of-life recycling of zinccoated steel also adds to this conservation because energy requirements for remelting steel and recovering the zinc are less than those required for producing the original metals.

“The zinc and galvanising industries understand that environmental and sustainability are integral to their future,” says Norton.

GROWTHPOINT BEGINS CONSTRUCTION ON CT GREEN OFFICE REFIT

Growthpoint Properties has commenced construction on a green office refurbishment of its 36 Hans Strijdom Building, the Cape Town headquarters of Ninety One, in a move that reinforces both companies’ commitment to the Cape Town CBD and to sustainability.

Ninety One, a global investment manager with South African roots, has been based at the Growthpoint-owned building in the Cape Town Foreshore for over two decades. Ninety One evaluated a number of options for its offices, including new construction, as its co-tenant in the building prepared

to move to new premises. Its decision to remain at 36 Hans Strijdom was strongly driven by its net-zero carbon aspirations.

Growthpoint welcomed the move, committing to an extensive green revamp of the property as Ninety One signed a 15-year lease for the

building’s entire 12 800m² of lettable area. Growthpoint has been at the forefront of environmental innovation in the property sector in SA, establishing green building as an accepted practice in the local commercial property sector and now driving the adoption of renewable energy in this space. Its own net-zero goal is to be carbon-neutral by 2050.

“We’re thrilled to continue our long-standing partnership with Ninety One. Remodelling this landmark building to the highest environmental standards is a testament to our mutual vision for a more sustainable future,” says Paul Kollenberg, Growthpoint head of asset management: offices.

Growthpoint’s refurbishment of 36 Hans Strijdom is being guided by sustainability goals rather than appearances, so while it will essentially deliver a new, lower-carbon building, the changes will mostly be visible from inside the building.

To begin with, a significant amount of embodied carbon is being salvaged by reusing the entire building structure. Among the environmentally friendly building improvements are an on-site solar plant, energyefficient displacement

air-conditioning and highperformance glazing. Energyhungry escalators will be replaced by circulation stairs in the new layout to reduce power consumption.

Furthermore, 36 Hans Strijdom was the first building in the Mother City to receive clean, green energy wheeled via the city’s energy grid, as part of the City of Cape Town’s wheeling pilot project. This is possible thanks to Growthpoint’s partnership with licensed electricity trader Etana Energy, which is a selected pilot participant. Solar energy generated at Growthpoint’s The Constantia Village shopping centre is already being exported for use at the long-term home of Ninety One.

Growthpoint’s investment in this green refit demonstrates its continued belief in the value of the Cape Town CBD and in the power of projects such as this to support sustainable built environments. The company owns 360 000m² of offices in the Western Cape.

Commenting on its decision to sign a 15-year lease for the entire lettable area, MD of Ninety One Thabo Khojane says: “Ninety One is a growing global business. This building has the space to accommodate a growing staff complement, as we’re increasingly on-shoring many of our global roles for South Africans, thus creating

much-needed jobs locally.” “Green office refits such as this one help lower carbon footprints and save energy. These efforts revitalise standing structures and create modern, sustainable spaces that contribute positively to their surroundings. By focusing on sustainable practices, we aim to enhance the urban landscape, while reducing environmental impact,” says Kollenberg.

Construction will take approximately 12 months to complete, with the building’s milestone installation of its new flush-glazed façade taking place in the final quarter of this year. Ninety One has relocated to temporary offices for the construction period and will return to its greener home upon completion, which is scheduled for July 2025.

“GROWTHPOINT PROPERTIES HAS COMMENCED CONSTRUCTION ON A GREEN OFFICE REFURBISHMENT OF ITS 36 HANS STRIJDOM BUILDING, THE CAPE TOWN HEADQUARTERS OF NINETY ONE, IN A MOVE THAT REINFORCES BOTH COMPANIES’ COMMITMENT TO THE CAPE TOWN CBD AND TO SUSTAINABILITY.”

BUILDING FOR A COMMUNITY

AfriSam, a leading construction materials company, has reaffirmed its dedication to the sustainable development of the communities surrounding its operations with the completion of the Verulam Community Hall. This initiative not only showcases the company’s commitment to social responsibility, but also highlights its support for local small, medium and micro-enterprises (SMMEs) and the creation of employment opportunities for community members.

The Verulam Community Hall, constructed by a local SMME, stands as a testament to AfriSam’s ongoing efforts to uplift and empower the communities in which it operates. The hall, which has been thoughtfully designed to meet the needs of the local residents, features a fully equipped kitchen and modern ablution facilities, ensuring a comfortable and functional space for various

community activities.

In line with AfriSam’s commitment to environmental sustainability, the hall incorporates several ecofriendly features. A water tank has been installed to collect rainwater, promoting water conservation and reducing reliance on municipal resources. Additionally, the hall’s surroundings have been enhanced with the installation of paving, providing a safe and accessible area for community members and a dedicated parking area has been provided to accommodate visitors.

By engaging a local SMME for the construction of the Verulam Community Hall, AfriSam has not only contributed to the economic growth of the community, but has also fostered skills development and job creation. The project has provided employment opportunities for local community members, empowering them to contribute to the development of

their own community and improve their livelihoods.

Commenting on the completion of the hall, AfriSam’s community development professional, Senzi Mabaso, stated: “We’re proud to have partnered with a local SMME for this project, as it aligns with our commitment to supporting local businesses and uplifting the communities in which we operate. The Verulam Community Hall will serve as a hub for various community activities, fostering social cohesion and providing a space for personal and collective growth.”

AfriSam remains dedicated to its sustainable development initiatives, continuously seeking opportunities to make a positive impact on the communities it serves. The completion of the Verulam Community Hall exemplifies its commitment to creating concrete possibilities for all.

THE ART OF UPLIFTMENT

CAPTAINS OF CONSTRUCTION

Africa (MBSA)

Hilton Haakonsen, project manager: SEF Project, National Arts Festival

Mnisi is an admitted attorney of the High Court of SA, with more than 15 years postadmission experience. He started his law career in 2002 at Madelein Nel Attorneys and practised at law firm Johan Jacobs & Malcolm Moodie (JJMM) Inc until 2005.

WHAT IS YOUR PERSONAL AND PROFESSIONAL BACKGROUND?

He has worked for the revenue department of the City of Johannesburg Metropolitan Municipality and as the CEO of the Institute of Municipal Finance Officers. He has also served on the boards of the Playhouse Company, the Independent Regulatory Board for Auditors, the Water Research Commission, Freedom Park and others.

Coming from a farming background, I got into project management nearly 20 years ago. I was operations manager for a private school in Grahamstown (now Makhanda) for almost 15 years and left to join the National Arts Festival (NAF) in my present capacity.

WHAT MOTIVATED YOU TO COMMIT TO THE MAKHANDA PROJECT?

Mnisi is a member of the Institute of Directors and of the Legal Practice Council. He currently serves on the boards of the National Home Builders Registration Council, the Joint Building Contracts Committee and the Construction Education and Training Authority.

We took on the role of working alongside our municipality and city occupants to do everything in our power to restore Makhanda to its former beauty and ensure that the festival-goers’ experience is top-class. This includes waste collection, road and pothole repairs, establishing food gardens for the pupils in 27 schools and three clinics, recycling initiatives and much more.

HOW DO YOU SEE THIS PROJECT UNFOLDING IN THE FUTURE?

When asked about the most challenging part of his job, he said “Challenges facing the construction industry have a way of becoming our challenges as industry leaders. When I see companies closing their businesses due to lack of work opportunities and other inhibitors, I feel the pain. When I see employees losing their jobs and livelihoods, I feel challenged at both professional and personal level. You kind of feel you should have done something to help the situation. Dealing with industry challenges such as violence on construction side, non-payment of contractors, declining construction sector are some of the challenges associated with the job.”

The project will run as long as there’s presidential funding. The job opportunities for the Makhanda residents – of whom about 57% are unemployed – are incredibly appreciated. The whole community is behind the project, since we’ve proved that we’re not a fly-by-night operation, but are here to improve the city in many ways and make a difference to the lives of its citizens, as well as of visitors.

We’re busy manufacturing recycled pavers from the glass bottles we crush, as well as shredding all waste plastic. The pavers are of a high quality and will be used to pave pavements around our city. As this manufacturing project grows, it will create employment for numerous members of the community, bring in an income to the project and remain a sustainable enterprise once the SEF Project is completed.

In relation to what is the most rewarding part of his job, he reflected on the role of the construction sector and the impact it has on people. He said “Whenever construction work happens, it’s not about the structure, it’s about dreams, hopes and aspirations. I remember when I was a little boy and my parents were planning and eventually built out house, it had some positive impact on me. It brought with it a lot of inspiration. So, whenever a house, school, library nor a road is built, it has a lot of impact on people, and we often don’t pay attention to that part. Being part of an industry body that deals with building industry matters at a national level is a fulfilment of a kind. Dealing with all things aimed at promotion and protecting the industry is the most rewarding part of my job.”

CREATIVE CONSTRUCTION USING COMPOSITES

Everybody loves the look of wood and timber has been used as a building material for centuries. Its natural, earthy tones have been crafted across a wide array of applications ranging from doors and walls to structural supports or frames for buildings, to furniture, floors and more.

However, natural wood is not the most durable building material for long-term usage. Its sensitivity to extended exposure to the elements, specifically water and sun, and the dwindling supply of this precious natural resource, means constant treatment and a limited lifespan, ultimately necessitating replacement. Wood’s beautiful, organic nature is the very factor limiting its functionality as a versatile, economically viable and, most

importantly, sustainable building material.

Fortunately, material technology has advanced to such an extent that companies such as Eva-Last are continuously developing new composite products that resemble the wood without any of its disadvantages.

Eva-Last composites are an advanced building material engineered to outperform traditional materials such as wood in terms of maintenance, weight and durability. Designed to emulate the grain, subtle colour variations and typical textures of timber, Eva-Last’s bamboo composites are increasingly finding application beyond the normal scope of construction into other creative uses.

Eva-Last's bamboo composite products are ideal for all outdoor applications like decks, docks, platforms, cladding, screening, railing and fencing due to their weather-resistant, slip-resistant and low-maintenance properties. Eva-Last’s Apex, Infinity and Eva-tech board options provide stability and durability. Creative applications such as bush bomas, bird hides, garden sheds, planters, pergolas, ceilings and furniture are only some examples of the versatility of Eva-Last composite products.

As more and more users come to appreciate the superior wear characteristics and versatility of bamboo composites, Eva-Last is fast becoming the go-to building material supplier in the global market.
