It was with great relief that we learned of the South African Reserve Bank’s Monetary Policy Committee Meeting decision to keep interest

rates unchanged despite concerns regarding the risk of further downgrades to local currency debt and the impact thereof on the stability of the domestic financial system as reported in the last edition.

This was on the back of reports that South Africa is set to avoid slipping into a technical recession this year following surprise improvements in mining and manufacturing output, although the economy remains under pressure due to recent credit downgrades.

The economy contracted 0,3% in the final quarter of 2016 and a second consecutive contraction would have pushed the economy into recession for the first time since the global financial crisis of 2009.

This can only be good for boosting confidence about a positive future outlook notwithstanding the negative publicity around the recent downgrades by ratings agencies especially if the assurances by the new Finance Minister that National Treasury will continue on the economic trajectory of fiscal consolidation hold true.

According to Econometrix director and chief economist Dr Azar Jammine, despite the hype around the latest sovereign downgrades, South Africa has not hit rock bottom, nor has it experienced the worst-case scenario.

“It is a misnomer to say we (South Africa) have gone junk – we actually have junk on only a portion of debt – the rest of it is still investment grade,” he said, noting the differing ratings approaches of the three ratings agencies and the differentiation of rand and foreign currency-issued debt.

“We haven’t had the worst-case scenario of a collapse in the rand that will cause our interest rates to soar,” he told

delegates at a Cliffe Dekker Hofmeyr ‘junk status’ seminar, in Sandton, pointing out that many positives still remained and many of the expected negative outcomes of becoming a sub-investment grade country had been somewhat muted.

“It is not a new thing for South Africa to be in junk and, technically, only a portion of it was in junk,” he reiterated, commenting that the disappointment emerged from the timing of the downgrades – a moment where positivity was starting to shine through and South Africa was on a path of recovery.

He cited the overestimated negative impact of the drought, the dissipation of electricity constraints, stable industrial relations, lower-than-expected inflation, the unlikelihood of interest rate hikes and strong business balance sheets. This underscores the potential positive impact that greater private sector investment can have in staving off further economic deterioration to mitigate downgrades.

We are therefore buoyed by the foregoing and call for greater embracing, support and acceptance of public-private-partnerships (PPPs) in the procurement and delivery of key economic infrastructure investments to stimulate demand and boost activity in the construction sector.

This can translate into greater investment in artisanal skills development and to build capacity for the sector to be ready for example for the R138 billion allocated for infrastructure development in Gauteng over the next three to five years while keeping a sharp focus on transformation as well as social and economic inclusion using such expenditure as a strategic lever and catalyst.

As of the beginning of April 2017, Master Builders SA engaged two graduates for an internship programme to provide them with an opportunity to gain practical, work-related

experience. The internship programme will run for a six-month period up to 30 September 2017 and will see them being an integral part of the team preparing for the 2017 Congress.

The two graduates who succeeded in the selection process are Matshidisho Swartz and Peace Vilakazi. They completed their undergraduate studies in 2016, having sat for the Bachelor of Commerce Degree with the CTI Education Group. Speaking of the programme’s structure, Master Builders’ Business Development and Marketing Manager, Mr Terrence Mwase said that: “The objective of the programme is to utilise the congress preparation period as the ideal training space for the graduates, allowing them to match theoretical aspects of what they have acquired in university, to practical aspects of working on a real business project.”

When asked about how they have benefited thus far, one of the graduates, Matshidisho said: “Often students don’t really know what they are going to do after completing their qualification and I, for one, also fell under that group. This programme has given me an opportunity to marry

theoretical appreciation with the practical and industrial application, and has granted me the opportunity to gain the necessary exposure and to learn more – as one never stops learning.”

Regarding his role in the company, Peace said that he has so far enjoyed engaging with the building industry at various platforms, inform potential members about benefits and generative opportunities of being part of a large and representative body such as Master Builders. “I have attended several expos so far, and have enjoyed the challenge of meeting with representatives from different fields of the industry and learn about how they all contribute towards the betterment of the industry.”

It is envisioned that the programme will be an annual one, where new graduates are contracted each year.

Prof Hare was the recipient of the conference best paper award, which award is named after the late Prof Jimmie Hinze, a past-International Coordinator of W099. Prof Alistair Gibb, Loughborough University, delivered the welcome cocktail function address on Sunday evening, and Charissa Bloomberg, a celebrity psychologist, delivered the gala dinner address ‘integrity leadership’ on the Monday night.

Dr Fred Sherratt led the Rant (a discussion forum): Mirror, Mirror on the Wall . . . What are academics really doing for the People in Construction?

Two separate half-day workshops were presented on the Sunday prior to the actual conference, namely ‘Construction Ergonomics’ in the morning, and ‘Designing for Construction Health and Safety’ in the afternoon.

The conference entailed the presentation of 57 double blind peer reviewed scientific papers emanating from 16 countries, and four keynote addresses presented over two days.

The four keynote addresses were presented by: the Construction Industry Development Board (cidb) – Dr Rodney Milford; the Federated Employers Mutual Assurance Company (FEM) – Hermann Enoch; Peri Scaffolding – Riaan Brits; and Prof Billy Hare of Glasgow Caledonian University.

Towards better Safety, Health, Wellbeing, and Life in Construction

The Joint CIB W099 and TG59 International Safety, Health, and People in Construction Conference held in Cape Town in June was jointly hosted by the Nelson Mandela

Metropolitan University and the Central University of Technology, Free State under the theme Towards better Safety, Health, Wellbeing, and Life in Construction.

CIB is the acronym of the abbreviated French (former) name: Conseil International

du Bâtiment (International Council for Building), which full name was changed to ‘International

Council for Research and Innovation in Building and Construction’ in 1998.

CIB was established in 1953 as an Association whose objectives were to stimulate and facilitate

international cooperation and information exchange between governmental research institutes in the

building and construction sector, with an emphasis on those institutes engaged in

technical fields of research.

Working Commission W099 is committed to the advancement of the safety and health (S&H)

of construction workers, and Task Group TG59 focuses on human resource issues

in the construction industry. The rationale for the joint conference is the synergy between

W099 and TG59.

tyCPD point validation was as follows:

Conference: 3 CPD points (SACPCMP/CPD/17/012)

Workshops: 0.5 CPD point each (SACPCMP/CPD/17/013 & 014) Conference: 5 CPD pointsWorkshops: 1 CPD point each

OutcomesAccording to Professor John Smallwood. Professor of Construction Management at the Nelson Mandela Metropolitan University (NMMU), the closure entailed a group discussion.

In terms of TG59, the following were noted: ways to hear workers’ voices (engagement) need to be identified; researchers must interrogate their assumptions and findings; the impact of research in the field needs to be quantified; there are many ‘connection points’ between papers, and conditions, including welfare facilities, on projects need to be focused on.

In terms of W99, the consensus was: ‘Put the health back into H&S!’

With respect to the way forward, the following constitute the key interventions: a review of the various sessions’ papers to determine ‘connection points’; interrogation of the industry, and the management of the business and projects, to avert the perpetuation of the status quo (Rant summary); integrity-related research; more research involving the use of technology such as ICT; more focus on health, wellbeing, and welfare facilities and related, and enhancement of the link between W099 and TG59.

This year's African Construction and Totally Concrete Expo held at Gallagher Estate in Midrand in May was, according to the organisers, Africa's largest gathering of built

environment professionals to date.

The exhibition halls and outside exhibits were of an all-time high calibre and were well attended by delegates and visitors. In addition, the concurrent workshops and leadership forums delivered interesting and lively debate.

At the Captains of Construction and Infrastructure forum, the opening address was delivered by Hubert Danso, CEO Africa Investor led the session, who, by way of introduction pointed out that Africa's emerging markets would experience a growth from the present 16% to 60% by 2025.

Danso welcomed MEC of the Gauteng Department of Infrastructure Development, who delivered the keynote address on behalf of the Minister of Human Settlements, Lindiwe Sisulu, who was apparently unable to attend.

Mamabolo focused on government's future strategy to address the shortfall in housing, announcing a paradigm shift from the traditional large numbers of small housing projects to large and fully integrated projects, well located in or near urban growth points. Such projects would be designed from scratch as new towns of around 15 000 houses each, with fully integrated infrastructure built-in, including schools, shops, clinics, commercial areas, police stations, and business incubators. Once such projects were launched by government, Mamabolo pointed out that the private sector would then need to take the lead and that private/public sector partnerships (PPPs) would be key to the roll out these projects.

Paramount to this announcement is that for these projects the application of alternative (innovative) building systems (IBTs) have been approved for inclusion as an optional construction option. Mamabolo emphasised that such IBTs must conform to pre-set standards and must be accepted by communities.

Government grants will provide funding to municipalities for these projects, which will also provide massive opportunities within inner city development.

Wasnaar Hlabangwane, Chief Director of Construction Management (National), Department of Public Works followed with his address, delivered on behalf of the Minister of Public Works, Nathi Nhleko. Here again Nhleko emphasised the need for good governance and accountability and that PPPs are the way forward. On industry transformation, he noted that the construction industry is “top heavy with males” and that empowerment of women is to become a real practice.

In the panel discussion, comprising panellists: MEC Mamabolo; Chief Director Hlabangwane; Webster Mfebe – SAFCEC; Aubrey Tshalata, CEO, National African Federation for the Building Industry; Carlos – Moto-Engil; Jean-Pierre Labuschagne – Africa Lead Infrastructure and Capital Projects – Deloitte Kenya; Tshepo Nkosi, Head of Marketing, NHBRC. Danso led the discussion saying that innovative ways to finance projects through PPPs must be found. Far more clarification on projects is required and projects must be far better understood at design stage.

At this point Webster Mfebe, CEO, the South African Forum of Civil Engineering Contractors (SAFCEC) ignited the discussion with a passionate call on government to involve contractors at an early stage and to second professional people to projects, citing the City of London's progressive and successful initiatives in this regard, where contractors are compensated for their submission of ideas – even though they may not be awarded the contract.

“Appoint the right people with the requisite skills,” implored Mfebe. “On many projects there is sometimes no semblance of project management stability.”

Mfebe went on to highlight the problem of “absentee leadership”, where government leaders at various levels are simply not there and not available to engage with.

On PPPs, Mfebe said: “Although there is a strong case for PPPs there is an urgent need to streamline – eliminate the laborious stages of red tape. It is value-for-money that investors seek, along with good return on investment.”

New and distinctive ideas, a high standard of technical skill, creative flair, a good grasp of sustainability issues and a clear understanding of the complex role of built

structures within an evolving urban environment were just some of the reasons why Jean-Pierre Desvaux De Marigny from the University of KwaZulu-Natal won first prize at the Corobrik Architectural Awards in Johannesburg this evening. The competition, which has spanned three decades, has seen considerable changes in how young professionals in the architectural professional approach the built environment. Today, technological advances and sustainability imperatives are driving creativity. Innovation with a view to lightening the built environment’s environmental footprint together with an innate understanding of social and cultural imperatives within South Africa are just some of the reasons that this year’s judges singled out De Marigny’s dissertation. After presenting De Marigny with a cheque for R50 000, Corobrik managing director, Dirk Meyer, thanked this year’s judges for their invaluable input – Andre Eksteen, multi-award winning co-director at Earthworld Architects & Interiors, Tunde Oluwa, sustainable development guru and founder of Odyssey Architects SA and Tanzeem Razak, who is passionate about spatial transformation in South African cities and director and founding partner of Lemon Pebble Architects in Johannesburg. De Marigny was one of eight regional winners from the country’s major universities who were chosen during 2016. Each winner became a finalist who competed for the national title.

His thesis, entitled ‘Design for [bio] diversity’, explored the potential of architecture for ecological conservation, proposing an environmental awareness and water research facility in the context of Springfield industrial park/uMgeni River catchment area in Durban.

Research revealed that human existence relies heavily on bio diverse ecosystems to survive, however as population increases, urbanisation and industrialisation occurs, resulting in natural areas often being exploited and degraded, most critically affecting the earth's fresh water systems.

De Marigny’s proposed architectural solution aimed to draw an analogy between the machine-dominated environment of the Springfield industrial park and the natural ecosystems found within the uMgeni river. This was achieved through the concept of viewing architecture as similar to that of a mechanical prosthetic device, so that the architecture (industrial machine) could begin to act as rather a natural life support system in the context in which it exists (ecology).

Attaching to an existing 440 m long pedestrian walkway bridge spanning the width of the river the facility hosts minimal ecological footprint, in addition to providing direct access to the water body to ecologically filter both surface (plastics, rubbers, geo-polymers) and subsurface (human, industrial, agricultural) water pollutants that are accumulated as the watercourse passes through habited areas before reaching Durban’s coastline.

AfriSam recently commissioned a new cement blending and packing facility in Maseru to serve the Lesotho market. Significantly, this is the first cement manufacturing facility

established in the country.

Speaking at the official opening, Lesotho’s Prime Minister Dr Pakalitha Mosisili hailed the plant as a “significant milestone” for the region and a boost for local socio-economic development.

Dr Mosisili highlighted that in developed countries one job in the cement industry creates ten times more upstream and downstream jobs. “This figure may be four to five times higher in developing countries,” he said.

The capacity of the plant – over 200 000 tons a year of bagged cement – will meet the current local cement demand, while also being capable of producing specialised products for large infrastructure projects like the Lesotho Highlands water scheme.

The main raw material for the plant – milled clinker – is railed to Maseru in bulk wagons from AfriSam’s Ulco facility near Kimberley. This is beneficiated with pulverised fuel ash (PFA) from Lethabo power station near Vereeniging in the Free State.

According to AfriSam’s manager – strategic projects, Gavin Venter, the plant includes a sophisticated dual batch weighing system to accurately dose the milled clinker and the mineral components to predetermined ratios in the manufacture of the different cement products.

The plant has been designed to produce the standard range of products most commonly used by local customers, including AfriSam High Strength Cement (52,5 N) for specialist concrete applications; AfriSam All Purpose Cement (42,5 N) for concrete work, block-making, plaster work and other applications; AfriSam

Roadstab Cement (32,5 N) for road stabilisation; and AfriSam Starbuild (32,5 N) for applications not requiring high early-strength development.“However, the plant can easily and quickly accommodate other blends specified by customers who have particular requirements,” Venter says.

The plant’s packing system is a 60 ton per hour, four spout in-line European design, utilised in series with a robotic arm palletiser to pack and stack the cement bags. Two stretch-wrap machines cover the palletised cement bags with a waterproof cover, so they do not need to be stored under cover; this also facilitates loading and unloading operations at the plant and larger customer sites.

Venter adds that environmental issues have been stringently addressed by equipping the plant with dust filters that prevent the generation of dust and create a dust-free operation.

During the construction of the plant – most of which was completed within six months – AfriSam made extensive use of local service providers and suppliers, including architects and civil contractors; local workers were also employed during the construction process. Today, the plant has created a number of new positions including plant management, operators and maintenance staff, as well as downstream employment opportunities.

Looking ahead, the company has plans for the plant to become a significantly larger cement manufacturing facility.

“AfriSam has already put plans in place to expand the current blending and packing facility to include a clinker grinding plant,” Venter says. “This will expand the cement manufacturing process at this facility and will lead to further opportunities and benefits for the people of Lesotho.”

At the International Federation of Consulting Engineers' Group of African Member Associations (FIDIC-GAMA) 2017 Conference held at the Cape Town Convention Centre in

May, Local Organising Committee Chairperson, Nyeleti Director and GAMA Honorary Secretary, Abe Thela, said that the vast opportunities that Africa presents for infrastructure development attracts consulting engineers from all over the world to the continent.

According to the African Development Bank, the infrastructure need of sub-saharan Africa exceeds $93 billion annually over the next 10 years. To date, less than half that amount is being provided thus leaving a financing gap of more than $50 billion to fill.

More and more of these infrastructure projects are mega, some are built in one country and benefit another and others span across country borders. By their nature, these projects not only require intergovernmental partnerships but partnerships among consulting engineers to ensure their successful execution.

“So far we have seen more partnerships between consulting engineers from outside Africa and African firms than partnerships between African firms. Partnerships to facilitate infrastructure development across our borders are crucial to sustainable growth and development of the consulting engineering profession in Africa as well as in integrating our regions,” explained Thela

Thela stated that on the flip side of these opportunities there are challenges that must be dealt with to ensure sustainable infrastructure development in Africa. These challenges include, amongst others, insufficient investment in infrastructure development, corporate governance failure in both the public and the private sectors and requirements designed to exclude African consulting engineers from projects implemented by the Development Finance Institutions (DFI). These

requirements are perceived to favour consulting engineers of the country of origin of the DFI and often are supported by inappropriate procurement strategies.

In her keynote address to delegates, Cape Town Mayor Councillor Patricia de Lille said that partnerships are vital to achieving progress and believes that together, we can do great things and take the African continent to new heights by building on our past to create our own futures dynamic and vibrant African cities.

“In our work of building an ‘Opportunity City’, we recognise the important role that our fellow African countries and cities play in bringing progress and economic growth for our continent. We firmly believe in the Africa rising narrative, that it is Africa’s time,” she explained.

Consulting Engineers South Africa (CESA) President, Lynne Pretorius, outlined that the conference came at a time when the environment in which business is being conducted “extremely challenging”.

“South Africa has its own economic challenges currently, along with various social and political dynamics. These are all mirrored to some extent in the rest of Africa, as well as in the rest of the world, developed and developing countries alike. With global changes afoot, it is clear that the world as we know it, the consulting engineering environment is changing. Within this dynamic environment, CESA remains resilient and relevant in enabling Consulting Engineering Excellence in SA, the SADC bloc and further across our borders, added Pretorius.

GAMA President Elect Eng James N. Mwangi said that with the growing local content requirements in many African countries, partnerships are important in ensuring capacity building, skills development and transfer.

“We expect to see even greater competition in bids and greater focus on Africa by global firms. We further expect even better quality delivery especially for very large projects and projects requiring very specialised skills.”

The conference culminated in the formulation of several key resolutions, namely to explore upfront project development opportunities between member firms; to actively encourage collaboration and networking amongst member firms from respective countries; sharing of best practice solutions; and enhancing member associations' organisational capacity through encouraging regional cooperation initiatives.

A MDEC Property Development’s (AMDEC) The Yacht Club development is a picturesque, nautically inspired design, located on the Cape Town Foreshore in the Roggebaai Canal

Tourism Precinct near the Cape Town International Convention Centre (CTICC) and directly south of the new multi-million rand cruise liner terminal.

The Yacht Club, a multi-use development including commercial and residential space, is destined to become one of Cape Town’s most sought after destinations and is yet another prestigious AMDEC/Franki Africa partnership.

The site is situated on the Malmesbury group deposition of the Cape Peninsula, Cape Supergroup in the Foreshore area of the harbour reclamation development of the 1920s and 1940s. The shale bedrock is overlain by very stiff residual material followed by marine deposits and fill comprising of old harbour facilities, general tipped rubble and dredged sands.

The ground water table was intersected at an average depth of 0,86 m with the bedrock falling from around -0,84 m in the west to -2,9 m in the east (elevation levels in ASML).

Special attention was required to an existing sub-surface canal running south to north which intersects the eastern portion of the site with both the lateral support and piled foundation design modified to accommodate and maintain the integrity of this structure.

“It is evident that from a geotechnical perspective the Cape Town Foreshore is not the easiest area in which to operate. The varying ground conditions with old

rock-filled docks and piers and the high water table described above present a significant challenge,” says Franki’s Rod Schultz. “But our previous experience on the neighbouring Harbour Bridge and Canal Quays projects has given us a thorough understanding of the prevailing ground conditions in the area and enabled us to quickly offer our client the most cost-effective solution,” he says.

Schultz continued saying that it took some years of on-and-off development proposals by all concerned before AMDEC succeeded in producing a workable solution by securing the land and obtaining the necessary partnerships to go ahead.

Due to the past successful working partnerships between Franki and AMDEC, Franki was the preferred contractor for this challenging geotechnical work. “We know Franki’s exceptional capabilities in the Foreshore area, which

requires a special understanding of its complex geological conditions. We had no hesitation in awarding Franki this contract and their performance certainly lived up to expectations,” says AMDEC’s Project Manager Arnon van As.

Franki’s scope of works included the design and installation of the lateral support and foundation piling to this multi-storeyed, double-basement project, the excavation and disposal of some 65 000 m3 of bulk earthworks, 508 lm of lateral support and 271 no. foundation piles.

The soldier piles for the lateral support were a combination of 400 mmØ Continuous Flight Auger (CFA) piles and 325 mmØ Rotapiles tied back with a single row of anchors and gunite arches. The anchors had to be carefully positioned and inclined sufficiently to not intersect with the canal, which runs very close to the site.

CFA piling is a fast and economical system with no vibration and limited noise levels associated with it. “This was particularly advantageous on a site which is close to live canals and railway lines, contains a labyrinth of existing services and has neighbours who are particularly sensitive to noise,” says Schultz.

The main feature of the Rotapile system is its ability to penetrate boulders and rock formations. Socketing into hard rock is effected rapidly using the ‘Down The Hole Hammer’ (DTH) percussion drilling technique. As with CFA, noise levels are low and vibration limited.

Schultz says that the foundation piles were designed with flexibility in mind to meet the varying and sometimes unpredictable ground conditions. Three pile types were used: the Franki Driven Cast-in-Situ piles, Temporary Cased Augers and Oscillator piles with individual load bearing capacities from 2 300 kN to 10 000 kN.

To say that the Franki Pile is the most well known piling system in southern Africa is certainly no exaggeration. Developed circa 70 years ago it is still one of the most popular pile types in this region. Its main feature is the

large base formed at the toe of the pile and, in forming it, the end-bearing area is considerably increased. It is generally a very economical system, has an extensive range of pile sizes and, like the other piling systems used on The Yacht Club site, its noise levels are relatively low.

Another significant challenge on this project was the very demanding schedule. “This meant that the works not only had to be very carefully planned but also executed to perfection,” says Schultz.

He explains that AMDEC required a phased handover to the main building contractor so that the critical-path tower cores and basement sections could be started whilst Franki were still busy on site. “We started operations during the latter half of 2016 and completed everything on time and within budget by mid-March 2017,” he says.

Schultz paid tribute to Franki’s client, AMDEC, and to bulk earthworks contractor, Ross Demolition. “To have successfully completed this project on time we needed it to run like clockwork. This was facilitated by these two professional companies which pulled out all the stops to ensure that we could do it,” Schultz concluded.

At a sparkling event in Freedom Park Pretoria, dignitaries from Switzerland and South Africa bid farewell to the team from Swisscontact. It was a fitting finale for the eight-year Energy

Efficient Clay Brick (EECB) Project, a Swiss-funded environmental sustainability and climate change initiative for South Africa.

The project has had a major impact on the energy-efficiency of the brick-making industry, which is heavily reliant on fossil fuels like coal. The EECB brought together the skills and experience of entrepreneurs, environmental specialists, consultants, government and brick-makers to expand local knowledge, raise awareness and build capacity with regard to low carbon technologies and best practice.

The EECB project, which has been funded by the Swiss Agency for Development and Cooperation (SDC) and implemented in South Africa by Swisscontact, exceeded its objectives by successfully facilitating a 15% reduction in energy consumption and greenhouse gas emissions in the last four years – which will be an ongoing legacy for the South African clay brick sector.

Representing the project team of industry experts, Juancho Hagnauer described how the EECB project motivated, educated, facilitated and financed initiatives that mitigate climate impact and improve the air quality. Areas of intervention included:

• Workingdirectlywithbrick-makerstofacilitate economically viable, locally relevant firing and production technologies• Creatinganenablingenvironmentthroughaccessto finance as well as positive awareness of the need for environmental policies• Supportinbenchmarkingthecurrentstateofthe industry through the sector Life Cycle Assessment (LCA) and ongoing industry South African Clay Brick Sustainability Report • In-depthresearch,casestudiesandcost-benefit assessments for use by brick-makers on a wide range of energy-saving and low-emissions options for ongoing improvements

The EECB project will continue its good work under the direction of the Clay Brick Association of South Africa.

“As an industry, we are committed to make good use of the wealth of research done by the EECB team to improve the energy-efficiency of clay brick manufacturing processes,” confirms CBA President Musa Shangase.

“The CBA and its members continue their work into the future as we reduce our industry’s carbon footprint and emissions for the good of all South African communities.”

The EECB Project Team would like to express our gratitude and appreciation to all of our stakeholders from within the sector for this incredible journey of the last eight years. We need

to acknowledge and thank so many people who were instrumental in the success of the EECB Project.

The Clay Brick Association – both the Board and office bearers on the technical and marketing teams. All the brick makers and the clay brick sector as a whole. Consultants and service providers from so many companies who participated and provided expertise throughout the project.

NGOs, institutions and Government representatives who have stepped up and engaged with the industry. You have all walked the talk and have contributed to the outcomes of the EECB Project. Without your cooperation, efforts and inputs, we would not have been able to achieve all that we have. The EECB team thanks all our friends who invested the time and effort – as they have many times over the past eight years – to travel from all over South Africa to be at our closing event which was a celebration of the achievements of the EECB Project.

The EECB Team believes that we leave a sector more than capable of facing the challenges ahead. On the claybrick.org website are a wide range of free case-studies, ideas, cost-benefit reports, books, tools and knowledge to assist you in the months and years ahead. This we believe will contribute to a continuation of the various engagements between stakeholders, ensuring that clay brick is seen as the preferred sustainable building material. Personally, it has been a hugely rewarding journey. Thank you to everyone I have worked with or known prior to the project, as well as all of you that I have met and worked with during the project. I value your contribution to my personal development and knowledge. It could easily be a time of sadness, as a team that has operated well together ends this journey with you and we each go our own way. Instead of being sad though, we would rather see the positives and am excited about what can still be. We see clay brick producers measuring their energy intensities within their process, using the information to evaluate projects. We see visits by groups of brick producers visiting other brick producers where improvements in clay brick production are being shared, contributing to change. These two examples demonstrate to us the value of what we have achieved together with you. We look forward to over the coming years, even if we may not be directly involved, to be able to follow further development within the sector, in particular with regards to the implementation and demonstration of more sustainable production processes, ensuring the enduring benefits of clay brick are visible and recognised in the market place. On behalf of the entire EECB team: Luca, Musa Juancho, Michael, Lwandi, Bongi and Simise – it has been an absolute pleasure, thank you.

Kind Regards

The Energy Efficient Clay Brick (EECB) Project has followed a holistic, systematic approach to improving energy efficiency and reducing CO2 emissions in the South African clay brick sector. Over the lifespan of the project, CO2 emissions in the clay brick sector have been reduced by 320 000 tCO2 annually.

The EECB Project operates in a dynamic environment that includes a diverse set of stakeholders.

Stakeholder 1: ProducersDirect engagement and interventions with clay brick producers and their suppliers to shift to more energy efficient production practices.

Stakeholder 2: Public SectorFacilitating access to financing and incentive schemes and networking with public sector stakeholders to regulate and set sustainability and clean air standards in the clay brick sector.

Stakeholder 3: ConsumersEngaging with customers and specifiers to raise the awareness on energy efficiency improvements in the clay brick sector. Knowledgeable and committed buyers are key drivers of change.

The EECB facilitated on-site case studies at respected local brickworks, that harness technological innovations and best practice. This demonstrated that it is feasible to be both environmentally friendly and economically sustainable in both small and large operations.

Improved use of local resourcesIn the final assessment survey, the weighted average energy consumption has been reduced from 3,46 MJ/kg fired brick in 2013 to 2,97 MJ/kg fired brick in 2017 - a reduction of 14,1%!

Manufacturers were introduced to alternative technologies and international best practice. The Vertical Shaft Brick Kiln (VSBK) and the Habla Zig Zag Kiln proved most suitable for South African conditions and were implemented. Both these firing technologies reduce coal use and therefore emissions.

Research and case studies on various technologies have quantified potential energy savings as well as return on investment and payback periods. This ensures that brick

manufacturers make informed decisions about future capital improvements, which will continue to boost the sustainability of the industry.

Benefits for air quality & healthThe various interventions - especially the new firing methods - have drastically reduced the PM 10 (particulate matter) and Black Carbon by almost 90% at participating brick-makers, bringing it within the regulation limits of 50 ppm.

Direct large human health benefits come from the significant improvement at the various factories, reducing exposure to gases during operations and in surrounding communities

Long-term Knowledge TransferThe project operates in close co-operation with the Clay Brick Association of South Africa (CBA), the industry body that supports, informs and educates the majority of clay brick manufacturers in the formal sector.

By working hand-in-hand with the CBA, the EECB project was able to leverage its credibility and communications base and so reach producers and industry suppliers quickly and cost-effectively.

As part of its education initiatives, the EECB funded several publications and research studies including South Africa’s first industry-wide Life Cycle Assessment (LCA). All publications were distributed through the CBA to its members and other brick-makers in South Africa and internationally.

The project was handed over to the CBA for ongoing implementation in 2017. Through education and skills transfer, The EECB Project leaves behind an industry empowered and committed to continue to improve their sustainability.

The new Habla zig-zag kiln (HZZK) at Worcester Brick in the Western Cape uses just 66 grams of coal per kg of fired brick, compared with 129 grams of coal used by their clamp kilns. Emissions of CO2 per brick were halved, and particulate matter emissions were reduced by over 90%. The HZZK is an Australian

design adapted for South Africa. The Project won the 2017 United Nations Association of Australia Business Climate Action Award.

In what has become a very competitive market, food consumers want to choose their food in an attractive environment that reflects a clean, smart, healthy and comfortable place to shop and dine.

Creating the right atmosphere and impression, while supplying fresh and naturally produced produce is what the family-owned Jackson’s Real Food Market in Bryanston, Johannesburg, is all about – and they chose Ocon Brick red clay stock bricks to assist in their creation. Jackson’s Real Food Market store and restaurant opened late in 2016 with an objective to have not only natural foodstuffs, but also a green building to house the goods and patrons. Ocon Brick’s clay stock brick manufacturing process is constantly reviewed to ensure that ongoing improvements in energy efficiencies is achieved through reducing carbon emissions, resulting in their clay stock bricks having less embodied energy compared to other building materials such as glass, aluminium and particleboard. Nigel Jackson of Alan Grant Construction commented: “We have always used Ocon Brick’s clay stock bricks on our projects because of the good and reliable service they give us. We chose the red coloured clay stock brick because it was perfect for the atmosphere we were trying to create and it looks very earthy and natural which is what are our new store is about.

“Delivery space was quite limited, and we encountered some water flooding issues on site during the groundwork stage as well as the normal rainy season downpours, so it

was imperative that the deliveries from Ocon Brick were scheduled accordingly. We had amazing scheduling service from Ocon Brick and they never once let us down even at short notice. The skill of the Ocon Brick drivers was outstanding as they manoeuvred their trucks into our small siding for off-loading,” said Jackson.

“Because uniformity was essential for our new store, we asked Ocon Brick to sort the required 500 000 red clay stock bricks for us to ensure that the colour match after manufacture was consistent, which they did with 100% accuracy. The aesthetics at the Bryanston store is exactly what we wanted. We are very happy with the brick finish,” said Jackson.

Ocon Brick’s Sales Representative, Lucas Steyn added: “The project did encounter flooding issues which interrupted our delivery scheduling, but we realise that every project has its challenges and we understand when deliveries need to be rescheduled at the last minute. It is our flexibility in this regard that has always stood us in good stead coupled with a quality product offering.”

The company’s clay stock bricks are recognised for their consistency in longevity, strength, durability and quality. Ocon Brick has supplied bricks to projects such as Central Square, Sandton; Vaal University of Technology; DSTV City, Randburg and most major projects in the last 25 years.

Technicrete ISG and Rocla are other subsidiaries within the Infrastructure Specialist Group.

k Integral to its ongoing product innovation and sustainability programmes, Corobrik developed the now well-known Corojem “through-the-wall” clay face brick walling system a number of years ago.

This system was value engineered specifically for the affordable housing segment, with the objective of producing a lower cost brick which is not only significantly less costly than conventional face-bricks, but which is also aesthetically pleasing and which simultaneously reduces transport and construction costs.

Corojem, which is manufactured at Corobrik's Rietvlei, Lawley, Odendaalsrus and Kopano (Meyerton) factories, is well received in the market and is doing very well in the affordable home market – as is demonstrated in the sales figures reported by Corobrik for the past 12 months where over 26 million Corojem bricks were sold.

“The National Building Regulations allow for external masonry walls of a minimum of 140 mm thickness,” says Musa Shangase, commercial director of Corobrik. “And the Corojem brick is one of Corobrik's responses to the challenge of government to provide sound, durable maintenance-free clay brick houses for low-cost housing within the budget constraints of the government housing subsidy industry.”

The Corojem wall is the forerunner of all accepted through-the-wall clay masonry systems and is widely used for both single and double-storey buildings in inland climatic zones which are less prone to driven rain. Its excellent economy is due to the use of very practical clay face Corojem bricks which measure 222(l) x 150(w) x 73(h) mm.

Corojem versus standard imperial brickWith lighter mass per m2 to transport and move around the site than for conventional twin-skin walling, less mortar, and higher productivity – Corojem enables savings in the order of 25 to 35% for labour and 30 to 40% reduction in transport costs.

The Corojem walling system satisfies the National Building Regulations for single and double-storey dwellings as well as commercial and industrial buildings.

“The thermal benefits of building with Corojem face-brick are also of huge value in the South African context with its extreme climatic conditions,” continued Shangase.

“But clay brick has many other benefits that support its green building credentials: its material density provides a natural sound barrier facilitating quiet indoor environments and its mineral properties prevent the release of volatile organic compounds (VOCs) at levels which could impinge on indoor air quality. They also facilitate the absorption and release of moisture from the air to help keep humidity within a 40 to 60% level for healthy living. This, in turn, promotes comfort, wellness and productivity.”

“There is no doubt that clay brick delivers enduring structural integrity, creating durable and secure buildings in line with the ongoing trend towards a more responsible and sustainable built environment,” concludes Shangase.

While there are a few misconceptions around the fire performance of timber, structural timber for roofing is both commonplace and performs well under fire conditions. As

with every aspect of building, timber roof trusses must be manufactured and erected in line with the National Building Regulations and SANS 10400, which provide for fire safety.

Building regulations, set in place by bodies such as the South African Bureau of Standards (SABS) after extensive research and consultation with industry experts, consider all aspects of a given building material’s composition and properties to ensure that it meets the same safety and performance standard as any other building material in the same application.

Fire regulations relating to timber roof trusses state the following: • Each independent dwelling unit situated on either side of a fire wall must have its own bracing system within its roof structure, regardless of the fire wall projecting above the roof covering or not.

• The fire regulations do not state the size of a permissible gap between timber members bearing on either side of the fire wall. However, trusses passing through a fire wall must be split into separate trusses.

• The regulation states that “No part of the roof assembly, made of wood or any other combustible material, shall pass through the separating wall.”

• No tile underlay or insulation may pass over the fire wall.

The Department of Public Works’ revised Guide to Architects on the subject of fire safety (1998: page 3), addresses the matter of fire walls in roof spaces as follows:

“Fire walls, where required, shall be carried up tightly against the underside of the floor except that combustible minor structural members, such as battens, to which roofing material is directly fastened, may be permitted. Purlins must not penetrate a fire wall for a distance greater than 80 mm, but if they penetrate from both sides of the wall, at least 80 mm of non-combustible material must separate them.”

While the Institute for Timber Construction South Africa (ITC-SA) does not make the regulations governing timber construction in South Africa, as part of its endeavours to promote and protect the industry, its players and the general public, it interprets and disseminates them. It is the responsibility of all players, from the manufacture to erection and inspection of timber roof trusses to enforce the regulations; even engineers who sign off on a non-compliant roof structure could well be put to task by the Engineering Council of South Africa (ECSA).

Professor Walter Burdzik of the Department of Civil Engineering at the University of Pretoria confirms,“Any failure of a truss plant or roof inspector to insist on the separation of roofs per fire regulations needs to be reported to the ITC-SA. The same principle applies to low-cost housing; just because a roof is over a low-cost house does not justify deviating from National Building Regulations.”

The Institute thus urges all responsible along the timber roof truss value chain to play their part and act in accordance with both the National Building Regulations SANS 10400 and Building Standards Act 103 of 1977.

Safintra South Africa recently hosted built-environment professionals at presentations in Cape Town, Polokwane and Johannesburg, showcasing the new Saflok 700 clip,

Versatile® – a profiled metal sheet with the aesthetic of clay tiles, and other product developments. The innovations illustrate how steel roofing is used to create weatherproof, aesthetically pleasing, and more sustainable buildings.

Reducing carbon footprintBuildings must rise to the challenges posed by global warming, whilst also addressing the challenges of rising energy costs and water availability, and of course ensuring the financial returns required by the investor over the life of the building.

Metal roof sheeting has functionality well beyond that of simply being the upper surface of a building. By its nature, metal roofing can also perform in creating a thermally effective part of the building envelope, and as an effective substrate on which to mount or connect green technologies such as solar and water harvesting technologies.

Metal roofing has excellent sustainability credentials, and its versatility makes it the material of choice for a variety of architectural styles ranging from traditional to modern. It is however the functional performance that truly sets it apart.

Saflok 700 engineeringFulfilling the Kaizen philosophy of continuous improvement, Safintra is dedicated to promoting best practice in the built environment, and for this reason invests significantly in innovative technologies that solve the ever-changing needs in the industry and environment.

The ever-popular Saflok 700 concealed fix clip is one such a development. The new clip features a solid anchor base, ensuring excellent engagement at every rib. The Saflok 700 remains popular as the longitudinal rib embossing

strengthens the sheet and allows for excellent water run-off and minimal dust collection.

In recent tests, the new Saflok clip achieved over 2 kPa hold down (factored) in negative wind uplift load tests at maximum span.

Safintra also provides: • Arangeofclampsthatwillmaketheroofasourceof power without compromising the performance or warranty of the roof sheeting. Metal roofing is also ideal to maximise water harvesting efforts.• Tominimisemaintenancecosts,Safintraoffersthe range of Fixtite® fasteners which will have a life expectancy to match the roof sheeting.• Toreduceenergycostsandlowertheenvironmental impact of asbestos disposal, Safintra offers an over- roofing and roof spacer system which ensures SANS regulations are adhered to.

As is to be expected the groundsmen at Twickenham go about their work with the highest level of professionalism, paying close attention to detail and best practice in care of

the environment.

We are of course referring to the new Twickenham residential development in Victory Park, Linden, Johannesburg, where Renico Construction is preparing the site for a 144 unit upmarket residential complex.As with all Renico projects, work at Twickenham is

progressing like a well-oiled machine. South African Builder met with project manager Deon Grimbeek and site manager Hennie van der Merwe, who briefed us about the site preparation aspects of the project and challenges being addressed.

“Presently we are at land preparation and services construction stage,” said Grimbeek. “The property is on a relatively steep gradient with significant natural ground water which we need to work around and which is mildly challenging as we prepare the terraced areas prior to construction.”

The groundwater however is a distinct advantage for the Renico Twickenham team: by installing a borehole, which is just three metres deep, borehole water is utilised for all site preparation and building needs.

In addition to his considerable experience and expertise in construction and 11 years of service with Renico, van der Merwe is an avid gardener and has proudly taken charge of relocating the stately palm trees on the property for subsequent placement on completion of construction. “These trees are very adaptable to relocation and do rather well,” said van der Merwe. “It's important to note too that on all of our sites we take care to plant indigenous trees.”

The ground slope has demanded close attention to the design and construction of a series of retaining walls, designed and built by Powergate Construction using Technicrete retaining wall products. All rebar reinforcing has been supplied by African Reinforcing. Renico Construction is renowned for forging close long-term relationships with its suppliers, a policy which yields an important level of ongoing trust, understanding and problem-solving capability across a wide range of project types.

On completion of the site preparation in June construction will commence with a view to project completion in March 2018.

The ambitious multi-billion rand Precinct 14 in Roodepoort, a joint venture by Atterbury and Century Property Development, is poised to enter the construction phase next month.

The design of the 100 000 m² Precinct 14 mixed-use development is based on sustainable urban design principles to create a vibrant mixed-use scheme blending retail, leisure (gym and hotel) and commercial space with exclusive residential units in one integrated precinct. Precinct 14 will function as an environmentally responsible development featuring contemporary architectural designs to create a unique environment for prospective tenants and users alike.

Precinct 14 will consist of approximately 70 000 m² of P-grade office space, a 120-bed hotel, a 3 500 m² gymnasium, 100 residential units and a 13 000 m² convenience shopping centre.

Concept rationale The urban master plan that was created by a team of experts gives due consideration to city issues like traffic flow, security, public spaces, landscaping, environmental impact and governs the overall quality of developments within Precinct 14.

A 13 000 m² convenience shopping centre is planned at the centre of the development, with active restaurant edges which form a public interface between the retail, gym, hotel and offices, creating a safe connected environment for residents and users.

The office node is situated on the western boundary to tie into the existing MTN Corporate Campus and Constantia Park west of the N1 Western Bypass. The residential units on the eastern boundary link up with the established

Fairlands neighbourhood preserving the established character of the area. The hotel and gym is situated on the northern boundary next to the neighbouring Reddam Private school.

Location and accessPrecinct 14 is located on 14th Avenue just off the N1 Western Bypass. The planning of the road network for Precinct 14 allows for four major access points into the precinct.

A new interchange, Metro Boulevard Interchange, will be constructed as part of the precinct’s infrastructure responsibilities. The developer will construct additional lanes to the on and off-ramps of the 14th Avenue interchange. An additional carriage way will also be added to 14th Avenue from the MTN campus entrance to Davidson Road.

Precinct 14 construction poised to begin in July 2017

29JUNE 2017

Staff travelling from the north will have easy access via the Metro Boulevard Interchange or the upgraded 14th Avenue interchange. Driving from the south, access will be via the upgraded 14th Avenue interchange.

Security and access controlPrecinct 14 will be secured by a closed circuit CCTV system and roaming guards. Additional security will be provided at a building level via internal gatehouses, infra-red cameras and biometric access control systems. The goal of the precinct is to create a city-like environment with perimeter fencing and visible security barriers.

Data and IT infrastructureThe development is located directly adjacent to MTN’s main campus and data centres. The information and telecommunication infrastructure to the area is therefore inequivalent with fibre optic networks available linking to

Teraco. Being in close proximity to such networks holds significant benefits to users of Precinct 14.

Precinct managementA non-profit management and operations company will be established to oversee the running and upkeep of the entire precinct on a daily basis. In order to fulfil its obligations, the Precinct Management Company will charge a monthly levy to occupants of the precinct. The Precinct 14 Management Company will also oversee that design standards are maintained and that construction companies adhere to the rules during building periods.

(LTWP) Project in Kenya, with a key milestone of 120 wind turbines attaining Ready for Energisation (RFE) status in January 2017 and installation of all 365 turbines completed by 5 March in only 362 days.

WorleyParsons’ South Africa team was contracted in November 2014 by the LTWP consortium to provide overall project management, engineering review and construction management services for the Lake Turkana Wind Power Project, which will be the largest wind farm in Africa, and the world, when completed. The project scope included 365 Vestas wind turbines of 850 kW each, an electric grid collection system and a high voltage substation, upgrades to 210 km of existing road, an internal site road network and a 160-man self-contained permanent village. The substation, road infrastructure and village have been completed.

The wind turbines are expected to be commissioned in the last quarter of 2017 upon completion of the 428 km transmission line provided by Kenya Electricity Transmission Company.

“Despite some logistical, climatic and community challenges, we have delivered our scope of work to date for the LTWP Project within the stipulated time frame and budget,” says Tim Gaskell, Power Business Unit Manager for WorleyParsons RSA. “We have worked closely with the

customer and with the sub-contractors to address these challenges and proposed workable solutions. For example, as Lake Turkana is located within a desert-like environment, it seldom rains, but flash floods do occasionally occur and the existing road designs did not factor this in. We assisted with improving the road design to cope with flooding,” says Gaskell.

“We also deployed additional people to assist local sub-contractors to adhere to the high standards required for the project. We have a strong focus on localisation and social upliftment to ensure that the surrounding communities benefit from this project, and have placed particular emphasis on health and safety awareness as most of the local workforce has not been exposed to any health and safety practices,” he adds.

“Training and skills transfer is a priority on all projects and the LTWP Project has afforded us the opportunity to expose not only the local engineers from Kenya to a project of this magnitude, but also some of our junior engineers, which will stand us in good stead for future wind power projects,” says Stefan van Niekerk, WorleyParsons’ project manager for the LTWP Project.

The LTWP Project represents one of the biggest single private investments in Kenya’s history, and aims to supply 300 MW of reliable, low-cost wind turbine generator capacity to the Kenyan national grid, equivalent to about 15% of the country’s current installed electricity generating capacity.

Another milestone for WorleyParsons on Africa’s premier wind power project

Lafarge partners with Saldanha Municipality in quality affordable housing project

A handover ceremony of ten houses on 15 May 2017 in Saldanha showcased the active commitment to sustainable development of Lafarge Mining South

Africa (Lafarge), a member of the international LafargeHolcim group.

For the delighted beneficiaries of these ten 42 m2 houses in the White City community, the ceremony marked a day that was beyond their dreams. The quality new homes have been built by Lafarge in collaboration with the Saldanha Bay Local Municipality. Human Settlements Deputy Minister, Zou Kota-Fredericks, who attended the handover ceremony, commended Lafarge Mining South Africa for their commitment and hard work, and generosity.

The land the houses are built on was donated by Premier Fishing and serviced by the municipality, with the project creating a total of 88 jobs for members of the community.Speaking at the handover ceremony, Lafarge General Manager for Aggregates, Noriko Solomon said: “While the challenge to house South Africa’s people is a daunting one, the stakeholders in Saldanha can be proud of this positive milestone achievement. More than anything, this occasion celebrates the importance of working together – partnerships where each one contributes what it is best able to provide.”

The foundations and floors of the houses were built using guaranteed quality Readymix concrete from the Lafarge Saldanha Readymix plant, formulated with slag extender to enhance durability while reducing the carbon footprint of the construction. The Saldanha Quarry supplied the 19 mm aggregate used in the concrete.

Sika has announced the launch of new Sikaflex Crystal Clear, a transparent sealant that can be used for all contractor and DIY projects. Sikaflex Crystal Clear is a one-component,

transparent adhesive and sealant. Solvent-free, this multi-purpose product complements the industry-renowned basket of Sikaflex -11 FC, Sikaflex Pro-3i and Sikaflex AT Façade.

The product is suitable for use on most surfaces including metal, glass, concrete, plaster, plasterboard, wood surfaces, painted enamel, polyester and plastics. It is ideal for use on transparent surfaces such as glass, plastic or acrylic, due to its crystal clear application, but will invisibly blend into any coloured surfaces as well.

Sikaflex Crystal Clear is a joint sealant that offers excellent workability on vertical and horizontal joints, connection joints as well as for caulking between partitions, sealing of metal and wood constructions, ventilations and soundproofing of pipes. The versatile product can be used whenever a transparent bond line is needed.

This new sealant is 100% crystal clear and transparent. It offers good workability and low shrinkage during cure. Especially designed for professional interior finishing, it is the ideal product for contractors needing a transparent multi-purpose adhesive.

Sikaflex Crystal Clear is waterproof and watertight so can be used for assured sealing in bathrooms, kitchens and areas exposed to moisture.

New packagingSika has also recently implemented new and improved changes to its labelling and artwork. The product labels and packaging artwork have been re-branded to reflect Sika’s personality of building trust with its customers.

When the company's new corporate design was introduced in 2013, a basis for clearer lines and better reader orientation was created, which has now also been applied to Sika’s product packaging. The growing product range was taken into account in relation to space, as well as the changing needs of the market.

There are new label versions which are more suitable and usable for different user groups. These include designations, descriptions of a product, or the use of images. Sika has renewed pictures and drawings on the cartridges, boxes, bags and buckets, making it easier to identify which application field the specific product is suitable for – be it professional specialists, retail trade, craftsmen or DIY users.

The goal is to deliver a clear product message and simple orientation, which will make it even easier for customers to identify which Sika product they need and what that product can deliver for them. With the exception of the logo and the prominent use of Sika colours, the visibility of the Sika products has been improved and Sika has simultaneously created a unique, stand-alone product label design.

All Sika packaging is as recyclable as possible. All paper packaging is certificated, plastics are recycled for other productions, and the steel and other metal sheets of barrels are reused for production after use.

According to Sika there are no changes to form, fit or function of any of these products. Customers will receive the excellent quality to which they are accustomed.

Hot water costs can account for 40 to 60% of users’ total electricity bill. The newest player in the highly competitive water-heating sector offers solutions for the commercial, industrial

and residential markets: HydraTherm, and its growing range of high-quality, high-tech, energy-efficient water heating solutions.

Co-founder Michael Alton explains: “Our expertise lies in the design and specification of centralised hot-water plants for any project – we offer solutions for clients from large commercial enterprises right through to domestic home owners. We’ve used that expertise to develop our own brand of water-heating technology under the HydraTherm brand, and we can confidently promise the solutions the market is looking for.

“We set out to create high-quality, affordable and long-lasting hot-water solutions for private homes, the hospitality industry, the agricultural and healthcare sectors and we have achieved that aim. Quality and performance are at the forefront of our product philosophy. For this reason, we use only the very latest technology, with all parts and components carefully selected and tested to ensure ultimate efficiency, reliability and durability.”

The HydraTherm range currently includes integrated heat pumps and split hot water heat pumps, with gas water heaters and solar collectors in the final stages of development and also due for launch this year. The HydraTherm integrated heat pump is an energy-saving, cost-efficient solution for private homes, while the split heat pump offers a solution for industry at a highly competitive level of investment where payback periods are minimised and returns are maximised, says Alton.

HydraTherm’s split heat pumps use EVI technology combined with highly efficient air-to-water heat exchangers to ensure improved efficiencies in a wide

range of ambient temperature conditions and nominal coefficient performance figures of up to 4,5 to 1. For residential projects, HydraTherm can show that choosing the HydraTherm heat pump instead of a conventional geyser can save end users as much as 70% of their hot water costs.

Alton’s experience dates back to 2006 when, still a student, he launched a successful solar water-heating company, which was one of the first to participate in the Eskom SWH rebate programme. He then took up a position at another company in the same sector, where he and his team piloted the Eskom heat pump rebate programme, sustaining double-digit growth over the five-year period he was there. In 2014 he was the executive lead on the launch of a new SABS-SANS 151 compliant integrated heat pump.

“At HydraTherm we are continuously seeking new ways to deliver efficient solutions to water heating challenges,” says Alton. “As Eskom continues to cap the total power offered to new developments and the price of electricity increases, it is making more and more economic and practical sense to embrace solar and natural/LPG gas for water heating. To this end we are currently developing solar collectors and gas water heaters, which will be available later this year.”

But innovative products are not where it ends: HydraTherm provides the full spectrum of services to its buyers, from initial consultation, all the way through to personal after-sales service and revolutionary cloud support.

“Where unique solutions are required, we also design heating products on demand, to meet exact specifications,” adds Alton. ”We are very excited to launch these sophisticated products and look forward to revolutionising this sector.”
