DEPARTMENT OF PUBLIC WORKS

“ This meeting of the Executive Committee of AFCCA in South Africa is a significant milestone. As the Department of Public Works, which is responsible for policy and regulation of the

construction sector, we applaud the initiative of Master Builders South Africa in hosting the meeting in South Africa. This initiative also contributes towards the develop-ment of inter-regional trading opportunities on our continent. It is also very significant in light of the infrastructure development projects being delivered not only in South Africa but across the continent.

I want to applaud the work that MBSA does in South Africa. It is the leading national federation of registered employer associations representing construction and building contractors in the formal sector in South Africa.Let me also commend the important work done by AFCCA representing Construction Contractors in 30 different countries. The aims of AFCCA resonate with our own thinking in South Africa, and include:

Establishing ties among the contractors in African countries for developing the contracting sector.Promoting the contracting profession in fields of

building and public works, to realise the highest level of quality.Establishing groups of contractors in each African country and developing mechanisms to give a competitive advantage to African contractors.Establishing networks of African contractors in various African countries, and an effective data-base, in addition to establishing “consortiums” able to bid for large-scale projects.

The strengthening of the AFCCA organisation will have far-reaching benefits, not only for the African contractors but also for professionals operating within the built environment. Your efforts come at an important time in the his-tory of our continent. Africa is the fastest growing region in the world and at the core of that growth is infrastructure development.This is therefore an industry that is central to Af-rica’s growth. In relation to developments here in South Africa, I need to make you aware of the Infrastructure Development Plan outlined by the President of South Africa in 2012. There are 18 Stra-tegic Infrastructure Projects (SIPs) some of which will reach beyond the borders of South Africa.

Beyond our bordersSIP1: “Unlocking the Northern Mineral Belt”, centres on coal and mineral mining which will also have

Learning from Each OtherAt a function held recently at JHB’s Country Club, the Minister of Public Works welcomed the members of the Executive Committee of AFCCA – the African Federation of Construction Contractors Associations – from Egypt, Morocco, Ghana, Burundi, Malawi, Niger, Senegal, Sudan and South Africa.

major impacts in terms of water distribution, power generation and road and rail transport linkages.In coming months and years you will hear more about SIP 17: “Regional integration for African coopera-tion and development" which will concentrate on developing linkages with the rest of the region and the continent through energy, road, mining, water, port, rail and air links.In 2012, we met as ministers with our counterparts from Namibia to look at areas of possible coopera-tion. In relation to public works, we discussed, among others, the following areas:

Management of government immovable assets Maintenance of government properties Exchange programmes between built environ-ment professionals Labour intensive community projects for job cre-ation, and Development of construction technology.

The point I am making here is that we have so much that we can learn from each other. There are so many areas, in the construction sector, that require that we cooperate so that we move forward together. AFCCA is playing a role in this and, as government, we must be receptive to your needs and ideas so that we create an enabling environment for devel-opment and growth to take place.In order for Africa to grow and develop at the rate that many analysts are predicting it will grow, there needs to be very strong regional economic and social ties both within the public and the private sector. Growth and development in the continent will come about through cooperation and collabo-ration of our regions. Under the auspices of the AU this is already happening.

Reliance on the WestThe reliance on the West for our growth is no longer an option. Africans must determine their growth agenda and their growth path. And, it is through

initiatives such as those undertaken by AFCCA that we can begin to see the necessary cooperation among African countries, particularly in the private sector, needed to drive growth and development.The Renaissance of Africa will come from Africans working together and tackling their own problems in an African manner.

We have seen recently that services of the South African built environment professionals are in high demand for infrastructure projects across the continent. One of AFCCA’s aims is to promote the contracting and built environment professionals skills and services across the continent.My view is that these efforts must also include ad-vocating for measures to streamline and align the

qualification requirements of the built environment professionals across the continent so as to enable easier facilita-tion of export of the built environment professional services.A quantity surveyor and engineer who have qualified in Kenya or Ghana must be able to work on big infrastructure projects in Zambia and Morocco or South Africa without having to go through too much red tape to obtain the necessary permits to work in a different country. We need these skills everywhere on the continent. Where we have them, we must utilise them. Where we don’t have them, we must provide training.

Remove the red tapeWe do not have to depend on skills com-ing from Europe for our projects. This is what we are talking about when we talk about advancing the African agenda. We need to remove the red tape to al-

low export of services and businesses if we are to succeed as a continent.AFCCA also aims to champion sound governance of the built environment professions and to promote standards of training and development in the envi-ronment in order to protect the interests of the public and to maintain a sustainable built environment and natural environment. Let us never lose sight of this bigger picture.In relation to good governance, let me also mention the challenge of corruption, which is often associ-ated with the construction sector, the world over. It is a challenge I face every day in Public Works. We have to deal with corrupt officials working with corrupt businessmen, who siphon off public funds preventing optimal service delivery to the poor.The standards and ethical codes of practice that you put in place as contractors and the private sector will help us in the public sector as we clamp down on corrupt officials”.

JOE SLOVO DEVELOPMENT

Double DutyMulti-disciplinary consulting engineers, Gibb is involved in the third phase of Cape Town’s Joe Slovo Housing Development Project. Gibb was awarded the civil engineering portion of the project and its scope of work includes designing, obtaining approvals for design as well as supervising construction activities

The Joe Slovo Housing Development Project forms part of the larger N2 Gateway Project, and aims to transform the area's informal settlements into a low-cost housing development while

minimising the relocation of residents. “To achieve this, the housing units are double-storey single units, which deliver higher densities of dwelling units per hectare,” says GIBB’s lead engineer, Gareth Jansen.The housing units are 40m² and consist of two bed-rooms, a bathroom, kitchen sink, with ceilings and plastered and painted walls on the outside. “The phase three project is further divided into three stages, stages A, B and C. Phase 3A, which comprises 1 131 units is partially complete with 588 houses already built and delivered. Phase 3B, which comprises 929 units, is currently undergoing approval processes. Phase 3C’s construction will commence shortly,” says Gareth.He adds, “This project is the first of its kind. Due to the high density nature of the layout we had to create more units per street than usual. This, we achieved by building the units as double-storey single units. There were also substantial remedial earthworks

that had to take place.”Commenting on some of the challenges facing the project, Gareth says the exist-ing sewer and stormwater infrastructure posed a challenge due to the consum-ers’ use of the current infrastructure, (sewer blockages and debris block-ing the stormwater system). “As a

result, we had to design robust and higher level of service infrastructure than what would be the norm for services provided by the City of Cape Town.”In addition, Gareth says that the water table can be shallow during winter periods. The Jakkelsvlei canal, bounding the site, is on southern and east-ern boundaries along the N2 and N7 respectively. Therefore, the proposed site had to be raised to be above the 1:100 flood lines. “Bluegum road extension, which crosses the Jakkelsvlei canal and intersects with the N7, was designed and built as part of Phase 3A. This canal crossing comprises 3 x barrels of 3.6 x 3m box culverts, which had to accommodate the 1:100 major storm flow along the Jakkelsvlei canal,” explains Gareth.The next step for Gibb is to appoint a contractor for Phase 3C. “We will be involved in the day-to-day monitoring of the contractor’s work on site,” says Gareth, adding that GIBB’s involvement in the Joe Slovo Housing Development Project is through turnkey contractor, Sobambisana Community Developments.The Joe Slovo informal settlement was established in the late 1980s and grew rapidly due to its convenient location 12km outside of Cape Town and close to transport networks and educational facilities. It is one of the fastest-growing settlements in the city, with 2 748 households recorded in 2009. The project was launched after a devastating fire in 2005.GIBB, Wanda Pretorius, Tel: (011) 519-4600, Email: [email protected]

From informal settlement into low-cost housing development



Too often cheap land is earmarked for af-fordable housing settlements resulting in people living in 40 square metre homes, some 40 km away from where they work.

This, according to Francois, is just not sustain-able over the long term.“We can talk about the thousands of units that we need, about the shortage of houses at the lower end of the market or the oversupply at the top end, but ultimately the issue around affordable housing is much more profound than just a numbers game,” he says.Francois urges South Africa to re-imagine how land is used in creating human settlements, how cities look and how people live in them. “The cheap land that is purchased for afford-able housing projects means that people are further and further away from their place of work and where they play. We need to do it differently,” he adds. “We’ve seen a property boom in South Africa every twenty years or so. We had one in the sixties around urbanisation, one in the eighties around decentralisation and the last boom was around economic growth. I propose the next boom will be about transport.”

‘Ninja’ loans“We have just come out of a period where people wanted ‘ninja’ loans – in other words, I have no income, no job and no assets, but I still want a loan. This ultimately led to the global turmoil and the result is a very different market from that prior to 2009.”In the future, the competition for funding will

UCT’s Professor Francois Viruly predicts the next property boom will be centred around transportation

The next housing boom to hit South Africa will be centered around transportation according to Professor Francois Viruly from the University of Cape Town. He was speaking at the Affordable Housing Indaba held in Gauteng late last year.

become a lot more critical while funding institutions themselves will play a much more critical role.Francois emphasises that when planning for afford-able housing, it must be remembered that the poor-est of the poor in South Africa are rapidly shifting up the LSM chart. “Be this due to social grants or other means of income, the fact is we are seeing movement, hence the critical importance of the gap market/affordable market sector. And unless we can cater for the next level, then the current problems being experienced in the RDP sector will just replicate themselves in the next tranche of the property market.”He stresses the importance of people currently in the RDP sector, moving up into the affordable market while these people, in turn, move into the next segment.

Development density“An increase of ten million people is expected in South Africa’s cities by 2030 and if we don’t find solutions to the current challenges we face, we are going to have much worse on our hands. In Gauteng alone another ten million people are expected over the next ten years,” he said. “If we continue to buy cheap land far from the business centre we could have a situation where, at some point, people are commuting from Bloemfontein to work every day.”According to Francois part of the solution lies in using

land more appropriately. “We have to look at more density for our developments. In Jakarta 16 million people use less space than the 8,7 million people in Gauteng. We are not efficient in how we use space – not from an infrastructure or municipality perspective.”Francois calls on the municipalities to develop ar-eas faster to provide services. “Otherwise you have what is starting to happen in South Africa where people move in, build their own housing and then demand services. Ultimately you end up planning a town around a massive number of people which is a recipe for disaster.”South Africa is at a crossroads, Francois emphasises, and finding the right land closer to people’s work is imperative for successful delivery of housing.

Household budgets“The average South African household spends as much on transport as on housing while in the lower income groups, the figure increases from an average 20% of their income to as much as 40%. Compared with the 6% people spend in Accra on transport or the 4% in Kigali, it becomes clear that the solution lies in developing more housing along transport nodes.”Prof Francois Viruly, University of Cape TownTel: (021) 650-3442, Email: [email protected]

People’s GeyserSUCCESS STORY

A deep sense of caring for his fellow man inspired Patrick Ntuli to develop an energy-saving geyser that would help struggling South Africans to save money in the face of Eskom’s massive power price hikes.

J ust the thought of millions of people having to sacrifice buying food and other necessities, for electricity became a big issue for Patrick and he started to think of solutions for people to save power and avoid massive monthly bills. As a

geyser expert employed by Geyser Allied Products (GAP), a leading supplier of water heaters in South Africa, his thoughts naturally turned to geysers.

Patrick tells “Skills On Site”, “The geyser in your house is normally responsible for the biggest part of your monthly bill. So it stands to reason that efficient geysers have the best potential to cut electricity usage and save home-owners a lot of money. “My initial investigations showed that solar heaters and heat pumps obvi-ously have the greatest potential to cut electricity usage but they are hugely expensive to buy, even with rebates from Eskom. That’s when I started to think of developing an energy efficient standard-type geyser and that’s when I began developing my brainchild, the now famous Eco-Green Geyser.”

Everything done rightHe says when he told GAP manage-ment about his ideas they became equally excited and helped him put his ideas into practice. It was a time-consuming process and every-one at the company agreed that a project of such importance needed to be approached properly and that thorough research needed to be done on the available geysers.Patrick and a small team set up a carefully controlled test station and painstakingly began to benchmark all the different types of geysers available in South Africa. The idea was to see how much power they used and how effective their energy-saving devices were. After three long months of tests the results were out and Patrick used the research to come up with the final

design of South Africa’s first low-cost, low-energy geyser.“At the end of the study the answer to developing the Eco-Green Geyser was simple. We realised that the very best way to save power was to use a very big heating element at the bottom of the geyser to heat the water quickly. Then we added double the amount of insulation to keep it hot for longer – just like a coffee flask. In that way we use the same 2000W power input for a shorter space of time to heat the water and the insulation keeps it hot for the rest of the day without the need for the element until the hot water is used again,” Patrick says proudly.

Trial no errorTests carried out on GAP’s Eco-Green geyser showed that the principal worked. The geysers use at least 25% less power than normal geysers in the warm summer months. Although no tests have

been done in winter the results should be even more impressive when other geysers lose

a lot of heat as a result of thin insulation.Patrick’s understanding of local and rural conditions also drove him to use durable standard-type components that are freely available from any hardware store. As a result of these innovations, his geysers have become a huge success story and thousands of Eco-Green geysers have already been sold. “This has made the Eco-Geyser an environmentally friendly and energy efficient choice for housing devel-opments, especially outside the major cities where the installation, servicing and support of complex solar systems is too expensive or is not an option. Eco-Green geysers

can be installed and maintained by anyone who has been trained to install

standard geysers.”

Long roadPatrick has walked a long road to finding his success and has great plans for the future. During his schooling in Daveyton and later in Mpumalanga he was a diligent student and hard worker. Most holidays were spent

SUCCESS STORY

helping his Dad at his place of employment with South Africa’s biggest geyser supplier and here he learned everything there is to know about geysers.After school he enrolled to study Sales and Marketing with the University of Tshwane but his plans were cut short by the death of his father and a year later his mother. With no funds to study, he again found himself employed in the geyser industry this time providing training to installers and technicians. With enough funds raised, he went on to complete his National Diploma in 2005 and shortly thereafter joined GAP. Although the development and release of the Eco-Green Geyser is undeniably the highlight of his career, Patrick says he has shared many other highlights as part of the GAP team. Most recently his efforts to introduce GAP products, as well as the Eco-Green geyser to affordable and middle-class housing proj-ects are extremely rewarding. “We have wonderful and affordable solutions for developers and its just a matter of us getting the word out there,” he adds.

Singing his own tuneAfter hours the highly talented geyser man puts on a different face as a budding gospel singing star, enchanting his growing fan base with songs about succeeding in life. Having just finished his final exams to earn a degree in Marketing from Unisa, and with the launch of his second gospel CD about to be released, both his careers are set to take on new and exciting heights. Whatever his future holds he is ready to face the challenge.

“I am glad that thousands of households across the country are benefitting through my development of the Eco-Green geyser and in future I hope that my ongoing work to introduce these geysers to more housing developments is equally successful,” Patrick concludes.

WHAT HAPPENED?

At approximately 14h30, the injured party was offloading a truck that had arrived from the steel supplier. He was usually the crane operator but had to perform the slinging duties due to the Banksman not being there. While trying to sling the steel, he realised that there was no space to hook the sling properly.He had to hook the steel on the edge to be able to place a spacer in-between the steel sections, in order to hook the slings properly. While he was inserting the spacer, he bumped his hand on the load. His reaction was to signal to the crane operator to stop. The crane operator misinterpreted the signal and lowered the load onto the injured person’s hand.An Inspector witnessed the occurrence and ran to the load where the man’s hand was trapped. He re-hooked the sling and signalled the crane operator to lift the load which freed the man’s hand. The incident resulted in an open fracture to his right hand thumb.

WHAT CAUSED IT?

Immediate causes were improper lifting and loading as well as improper placement of tools, equipment

and materials. There was a lack of knowledge of hazards present allowing the wrong decision to be made and/or a lack of overall judgment.Root causes were inadequate ident i f ica-tion and enforcement of critical safety behav-iour with poor risk perception. In addition, poor skills resulted from inadequate practice, lack of performance and no coaching for the task.

CORRECTIVE ACTIONS:The best cure will be to remove the hazard. This can be achieved by considering an off-road/rough ter-rain forklift to offload the steel from the trucks and transporting it to the stacking area into the plant. This will eliminate the risk of employees being exposed to extensive manual handling, which is the reason for most serious injuries.The risk assessment training and methodology was improved with increased communication and more hands-on practice for operators and supervisors. Further efforts were made by asking the suppliers to place suitable packing between the steel and only having bundles that can be lifted by the crane or forklift.Management training, to improve safety awareness and correctly identify the needs of site personnel, was carried out. It also focused on improving the operational procedures and risk assessment process.

Skills on Site” speaks to Felix Woods of Nesandla Civils about his career in this field. Currently the site manager at the upgrade of a Solid Waste Disposal Plant in Alrode, we meet Felix

at his site office. “I work for a Civil Engineering construction company and our projects are specifically civil, sometimes

confused with building” he tells us. “Most involve things like water and sewer mains, stormwater drains, bridges, roads and so on. It’s not the same as building, where you’re putting up a house; our tasks are quite different.” In spite of this, he explains that most projects need similar principles to run smoothly. “Every project requires administration, labour, plant and materials, and each of these must be managed individually.”

The jobA project usually begins with a client asking a con-sulting engineer to design something for them. They

produce a plan and a Bill of Quantities to put prices on each item, such as excava-tion, laying pipes, backfilling and other requirements. These prices will be rough estimates to give the client a general picture of what’s needed and what it costs. This then goes to tender, which requires a site inspec-tion before different com-panies will give their rates to do the job. Once all the tenders are in, there will be an adjudication where the client will award the contract for the job. Usually the lowest quote will be chosen.“When we get on site, the engineer will give us a set of drawings and the Bill of Quantities. This can be differ-ent from the original tender

Construction projects are usually complicated – each must be managed like a business, with suppliers, materials, staff and deadlines. The job of a site manager is to see that all of these elements work together.

if they have found that there are variations from the original brief, however they will provide a set of instructions detailing these,” says Felix.

Begin the admin“This is where the administration begins. My main responsibility is to create a programme based on the drawings and the Bill of Quantities, stating how

long each stage will take and what is needed to complete it. This means I have to know the types and quantities of materials to order and when they must arrive. “My current assignment is a 12 month project and I’m here from day one. Every day I measure what’s been done and note it in the site diary, showing the

date, time and weather conditions. This information is supplied to the client with our monthly invoice, and it’s checked by the site engineer, so it has to be accurate.”

Good labourFelix explains that staff is another important area to manage. “I have to work out how many workers will be needed for each stage, and the tools that they will require; also whether they need to be skilled or unskilled. “Occupational Health & Safety (OHS) regulations are a big responsibility and they’re usually handled by a Health & Safety Officer, who makes sure that workers have safety boots, overalls, hard hats, goggles and other important equipment. There’s a lot of paperwork involved here and rules are very comprehensive so it has to be managed correctly,” he warns.“Safety regulations also mean that we must appoint operators who pass medical examinations and have the correct certification and training. Ultimately, if something goes wrong on site, the site manager is to blame.”

Disputes or grievancesHe adds that staff may be sourced either locally or

from the company’s own key personnel. “Some jobs are specialised, for example pipe layers, surveyors and mechanics, and it is useful to have these people on your staff. Of course, there’s also risk involved because when there’s no work you still need to pay their salaries.“If you source workers from the area around the project, usually it’s necessary to have a Community Liaison Officer to deal with these people directly and to bring any disputes or grievances to the attention of the site manager. We also have a foreman on site to manage the daily work. In South Africa this must be a person who can communicate with people from many different cultures, so a good foreman is very important.”He also emphasises the importance of looking after staff, not just in terms of safety but also financially. “Wages must be paid on time and it’s good to get to know your people and where they come from,” he continues.

Material needsOne of the big challenges of the job is ordering the right materials because often the site drawings are not detailed enough to give this information. However, when the materials are wrong, the proj-ect can’t continue. “It is my job to calculate exact

Specialist helpFelix tells us there are additional staff who are often involved in a project to make the job easier. These include:Quantity surveyor – this person measures work done and also calculates materials needed. Not every site has one but they save a lot of time and effort for the site manager.Engineer – in addition to the consulting engineer, some sites have a site engineer who can do designs of things such as formwork, as well as advise on any job that hasn’t been covered in detail in the original brief.Area foremen – in some projects, different areas have their own foreman to manage teams. For instance if a building has many floor, each floor may have a foreman who then answers to the head foreman.Surveyor – this is someone who ensures that coordinated setting out points are measured accurately before work begins. In many cases the site manager handles this task too. Hired equipment is often charged by the hour, so we have to be sure

The easiest way to restore a concrete floor.

A blasted concrete surface is full of pores and irregularities. It needs a significant amount of follow-up work, with the use of liquid leveling compound, then drying and secondary blasting before any other surface can be laid on top.

A scarified concrete surface is uneven and rough. This requires a lot of leveling compound and several hours’ extra work before you can use the finished surface.

A ground concrete surface is clean and even. It is a perfect bonding surface for carpet glue, epoxy, paint or primer. You can start putting down your new surface as soon as you finish grinding.

Grinding enables you to remove the old floor covering and level the

surface without damaging the floor. The rotating grinding disc works

horizontally, resulting in an even and flat surface with minimal need for

follow-up work.

Concrete grinding is the simplest and most efficient method for leveling

and restoring concrete flooring. A good floor grinder with diamond

tools will quickly loosen old floor coatings such as paint, epoxy or carpet

glue, while creating a perfect base for the new floor covering.

Efficient, e asy-to-use machines.

The PG 400 and PG 280, Husqvarna’s smaller grinders, are designed to be

convenient, easy to use and efficient. The compact design provides a

perfect view of the work surface and good access to edges. The

handlebars and control lever are ergonomically designed for the best

maneuverability. The rubber skirt, which rests on the floor, enables the

dust collector DC 1400 connected to the vacuum port to efficiently deal

with the grinding dust. This means a quick preparation time, even in

sensitive environments.

quantities, while considering things like wastage. “This can become quite complicated, for example, the drawing might say an area needs paving – I need to work out how many paving bricks, what colour, shape and strength. I must also know at what time they should arrive, and where they’re coming from, because if we need more and the supplier is far away, it will slow down production. It’s best to be absolutely spot-on with orders, not too much or too little.”

Materials can also be related to workers on site. If subcontractors are hired to handle certain tasks, they may supply their own materials, but if not, the site manager must order for them. “Although it’s complex, if you follow a logical sequence, you can plan ahead,” says Felix. “On this site, we’ll do the bulk earthworks, then dig trenches, build walls and do backfills. We also have to make room for mechanical components that will be installed by another contractor; these need concrete platforms with bolts to hold equipment in place, so I need to know what this machinery will be.”

Plant needsPlant (heavy construction equipment) is another important consideration and Felix tells us there are two types: that which belongs to the company, and that which must be hired. “Hired plant comes with its own problems,” he says. “Usually it costs money to get it to site. Also, if it comes with an operator, we have to be sure he meets the OHS requirements. Sometimes he will need to be housed, or transported to and from site. “Hired equipment is often charged by the hour, so we have to be sure that it is as productive as pos-sible. This usually means managing maintenance very carefully. Often routine maintenance, such as changing filters and oil, is done by the hire company, but things like flat tyres are always a concern.

Scheduling“Fuel is another requirement, as well as wear and tear. Worn teeth on an excavator can mean slower operation – if a machine is being charged by the hour and it’s taking three times as long to get the job done, you’re wasting money!“While these four areas may sound like they’re separate, they’re actually all related, since one can’t work properly if the others aren’t correct. If the materials don’t arrive the staff can’t work and the plant won’t be operating which puts the whole schedule behind and costs money.”

Father figureFelix admits that this is a job that has challenges and it’s suited to someone who is logical and enjoys problem-solving. “It’s difficult, but I like that about it. It’s like being the father of a big family. If there’s

In the heart of Blue Downs in Cape Town, MSP Holdings have built a tranquil, family friendly estate that is affordable and safe. “Skills on Site” speaks to John Coetzee, project director of MSP Holdings, about turning a vision into reality.

Belladonna estate is designed to give people the chance to enjoy family life,” says John. “Blue Downs is a highly dense area where people live just about on top of each other. There are large numbers of backyard dwellings. Statistics show about five people per housing unit when the average in Cape Town is about three people per unit. It was therefore im-portant to create an environment which would be spacious and give the opportunity to live the life occupants deserve at an affordable price.”The estate boasts a total of 740 units of which 460 are houses and 280 apartments. No matter where you live at the estate, a public open space is within a maximum walking distance of 120m.

“We devoted more than an adequate percentage of the development’s total to public spaces that allow for areas where children can play and adults can socialise,” he says.Connecting the parks, the play areas and the gar-dens are meandering pedestrian pathways.“You can densify an area as much as you like, but ultimately it is not about fitting as many people into the smallest area possible anymore. Many of the

people who are moving into these affordable market developments are trying to escape that very kind of living,” he explains.” It is therefore important to make sure there is adequate landscaping. Very unique to Belladonna is the centralised garden system that is designed in such a way that even though the indi-vidual homes don’t have large gardens, one can still have a family picnic not far from your home.”

Quality of life“Value for money is an important concept in this market and that is why there is such a high demand for developments such as these,” Johan adds.One size also does not fit all. Part of the allure of this estate lies in its variety. It is not row upon row of small box houses, but rather an extraordinary suburb that caters for anyone wanting to live in a one-bedroom apartment or a three-bedroom house.

Three apartments were designed for the estate. The first being 30 square metres offering a bathroom and one bedroom. The second apartment type is slightly bigger at 41 square metres with two bedrooms and a bathroom and the third is 50 square metres and has three bedrooms and one bathroom.

“There are more houses in the development as there was a higher demand than for apartments,” says John. “We designed and built five types of houses that cater across the spectrum of the affordable


housing market. This allows the entrant into this market who is earning around R7 000 a month the opportunity to buy an apartment, but at the same time there are also homes for someone who is pos-sibly earning R12 000.”With all the erf sites around 200 square meters, House type 1 which comprises 42 square metres has two standard bedrooms, bathroom and an open plan kitchen and living room. House type 2 only differs in that it is slightly bigger at 45 square metres and House type 3 is 50 square metres.House type 4 is 55 square metres and has three bed-rooms, one bathroom and an open plan kitchen and living room, while the largest house in the estate is 60 square metres also with three bedrooms.

Design featuresDesign features in all the units include quality plastered and painted exterior and interior walls, aluminum window frames and easy to clean tiled kitchen and bathroom floors. The bedrooms and entrance hall and living areas are all carpeted with television and telephone points already installed, ready for connection.The apartment kitchens are fitted with one bottom cupboard and a single sink and only one bedroom has built-in cupboards, but the option of extra bed-room cupboards is available.Each apartment has one parking bay allocated to it with additional bays available for visitors.And central to all of this, says John, is the quality and the high standards that has been maintained. “Being in the affordable price range, offering value

Being in the affordable price range, offering value for money, never means that quality should be sacrificed



for money, never means that quality should be sacrificed,” he continues. “We demand building standards of the highest quality and the same goes for the finishes.”

Safe and secureSafety plays a massive role in the success of devel-opments, maintains John. “All the apartments have remote access control and the perimeter has been fenced and electrified.”While the entire estate is walled in, it has open access to the public. A dedicated 24-hour patrolling system has been put in place and each single residential house is fitted with an alarm system.

Location, location, locationRiaan Roos, CEO and Managing Director of MSP Holdings believes that much of the quick uptake on Belladonna has been due to its location in Blue Downs.“There is very easy access to public transport sta-tions and routes, while a major shopping centre is only 1,4km away. At the same time there is a clinic a mere 1,5km from the estate and a number of good schools can be found in the surrounding area.“The estate also has three retail offerings that have already been sold and will be developed in the coming months while a site for a petrol station has also been earmarked along with a church and a crèche.”At the same time, the area has seen some major investment from large-scale regional businesses to

commercial operators in recent times. This will ulti-mately bring employment opportunities to residents in the area.

EducationBoth Riaan and John believe success in the affordable housing market goes hand in hand with education. “One must not forget many of the people who are buying in these developments have never applied for a mortgage, never owned a house and therefore it is important that one has a process in place that allows them to learn as they go.

“At Belladonna we hold regular buyers education sessions where we take potential buyers through the entire process of buying a house and what the impact will be on a family psychologically and physically. We explain the importance of up keeping one’s property, the impact of extending without proper plans for instance but at the same time information around budget fitness, about rates and levies and how to maximise one’s income is all discussed,” says Riaan.

Addressing concernsJohn agrees saying that developers have a massive role to play in educating the affordable housing market. “The bulk of our target market often doesn’t realise they can afford a house, but we also need to make sure they understand that there are respon-


There are responsibilities to owning a house not just to yourself but the people around you


22 Skills on Site Jan/Feb 2013A mother and child enjoy the playground that has been erected in one of the parks

The kitchen units have been designed in such a way that homeowners can add on as and when they have funds available


sibilities to owning a house not just to yourself but the people around you.”For this reason a master home association has been formulated in the development. “It has been broken down into streets that make up sub associations. So, every street chooses a chairman who represents them at the association,” explains John. “In this way issues can be addressed on a small scale, but also concerns and problems are immediately addressed rather than escalating into a massive concern for residents.”

According to Riaan through this association the education process is taken forward all the time. “One must remember when people move into a development of this kind, the way they have been living is changing completely and they don’t have a landlord to blame if something breaks or does not work. Having a tangible asset that can be used as security is the reality of owning your own home and that is the message we are bringing to our buyers.”

Affordable to all“Getting it right in this particular market is not always easy,” John concludes. “It takes a lot of experience to do a development like this within budget and then make a profit. At the same time the concept has to be sound, you have to get the mix right and create the balance within the development. Belladonna is your typical integrated development where the high-end unit is making the lower-end unit more af-fordable. We have also incorporated several very unique and necessary features to make it what it is. The success does ultimately lie in the detail because that is when you get it right.”MSP Holdings, Tel: 021 801 5400Email: [email protected], www.belladonnaestate.co.za

Addressing the Southern African Housing Federation (SAHF) conference in Cape Town last year, Kathi said the housing sup-ply shortage continues to drive up price.

“Households’ debt to disposable income remained above 75% in 2011 while consumers with impaired credit records are still above 46%. “Pared with stricter lending criteria due to the introduction of the National Credit Act and the consequences of the subprime market in the US, it has become increas-ingly difficult for average South Africans to afford a house in the gap market.”

Financial constraintsHe illustrated the magnitude of the South African problem saying out of 13,8 million households in South Africa, some 8,3 million (60%) fall within the government subsidy market, while 2,2 million house-holds (16%) belong to the gap market that have

an income of between R3501 and R7000. Another 1 million people, who earn from R7000 to R10 500 a year, belong to the second gap market, while some 0, 7 million households are in the affordable housing market earning between R10 500 and R15 000 per month.

Different interventions“We need to look at different interventions to im-prove housing affordability be it the introduction of subsidies for down payment and the reduction of administrative costs to interest rate subsidies and savings-based subsidies.”Mortgage insurance subsidies as well as plans to allow for renting to buy are critical in improving affordability.The limited supply of affordable stock for the gap market suggests that these instruments are not vi-able to resolve the housing affordability problems in South Africa unless we reach a place where we have adequate stock available. And that is where the biggest intervention is needed sooner rather than later,” he concludes.Gilbert Khathi, Tel: 012 444 5006, Email: [email protected]

The City of Cape Town has taken a two-pronged approach to housing delivery by bringing es-sential services to those on waiting lists while at the same time building more human settle-

ments. “Skills on Site” found out more at the recent South African Housing Foundation (SAHF) conference in Cape Town.

Positive impactThrough the provision of services to backyard dwell-ers, the City believes it can impact positively on the lives of the hundreds of people on the waiting list as it struggles to deal with its backlog of over 380 000 houses.According to councillor and member of the Mayoral Committee, Demetri Qually, the project is currently being undertaken in certain pilot sites in the city and is about providing backyard dwellers with basic infrastructure. This includes structures containing a toilet and a sink, linked to water mains, with the whole structure externally connected to electricity power sources.Demetri says most people waiting for houses are forced to live in backyard communities, but with this project they are not waiting for nothing.“This project will provide a model in the South Afri-

can context for doing more to provide services as part of a broader strategy dealing with the housing backlog.” He adds that housing is ultimately about building sustainable communities that link people together and to the rest of the city in which they live.

“We know there have been numerous sea-changes in the past two decades of how we think about housing provision. We started at a point of trying to build as many identical houses as possible in certain areas,” he said. “However, we quickly encountered problems that stemmed from the fact that these housing developments were not linked to broader communities and did not themselves foster a sense of community.”For this reason, Cape Town city fathers have shifted their thinking to take greater consideration of build-ing sustainable communities.“If we want to build an inclusive city that provides opportunities to all, we need to think constantly of innovative ways to improve service delivery,” he concludes. “And that includes addressing the conditions of people waiting for houses to live in.” Demetri Qually, Tel: (021) 400-1299Email: [email protected], www.capetown.gov.za

TRAINING

Sean Jones, a director of black-owned artisan training company, Artisan Training Institute (ATI) says one of the main problems with SE-TAs is that they are not “customer focused” and are “dictating to industry”, rather than

industry owning and driving the development pro-cesses required.

He says that should industry drive the development initiatives as opposed to the SETA’s, there would undoubtedly be productivity gains coupled with further job creation. Sean says South African business has a strong tradition of bullying small businesses. “Any change in strategy would need to cater for small business where most of the country’s future job creation will occur.”With the groundswell call to disband the SETAs and replace them with the old training boards or similar type structures, Sean says he is of the opinion that this is a notion that should not be summarily discounted – it should be looked at. “In most countries, there is a conflict between

the ministries of education and labour. Typically, in South Africa, the Department of Education has been winning this tug-of-war, unfortunately to the detriment of business. “The Department of Education has, and always will be, out of touch with business, especially where technical training is involved. Academics who have no experience in industry should under no circum-stances be involved in determining policy affecting development within business,” Sean warns.“FETs, for instance, are often not staffed with the right calibre of people. They are often staffed with school teachers who just don’t have the wherewithal, or acumen, to make a difference with the learners.“Right now funds are being misdirected, lost, siphoned, or misspent, in many instances, under the current SETA/FET set-up. It would now require major funds to up-skill FETs so that they apportion funding better, or simply meet their mandates that much better.“Whatever structure eventually replaces the SETA’s, they need to be under the jurisdiction of the Depart-ment of Labour, for a start. Secondly, they should have majority representation by industry, with further representation by small business”.An appropriate structure will run lean on adminis-tration with a strong focus on results as opposed to inflated salary packages for executives within the structures. Big packages do not necessarily mean big results as we have sadly experienced with the current SETA situation. Often more competent ad-ministrators could be employed at half the cost of some of the SETA CEO’s.Artisan Training Institute, Sean Jones, Tel: (011) 370-2809, www.ifta.co.za, www.artisantraining.co.za

Overhaul Called forThe South African education system is in turmoil with continuous reports abounding about teachers increasingly playing truant, that many are badly trained, that books are not even being delivered and that, on a higher education level, even the very existence of State Education Training. Authorities (SETAs) are now being questioned – with some people calling for the return of structures similar to the old training boards.

LEGAL EAGLE

The Part time “Employee”It often happens that those employees who are termed “part time” are viewed by some employers as not needing a contract. The worst is that students or school children are employed and no contract is forthcoming.

By the way, I do not believe in “bullying” any employee judging by some of the contracts I’ve seen lately. Employers should remember that the contract needs to be within reason

and should the CCMA have to decide if it is fair, or when the wise legal representative pulls it apart

for not being fair, then it is too late.When dealing with a part-time employee, make

sure all parties understand what is meant by this. Certain basic issues must be spelt out:Ensure that the “employee” knows how long the work will be available for. It might be one day, a week, only weekends or half a day during the week. Employers should develop a proper system and employees must question the situation they are enter-ing into. Lay the rules down before the

relationship starts. This is crucial to both the employer and employee.What is important is that a decent employ-ment agreement should be developed. These “agreements” are in some cases proper contracts and others just a letter. At the end of the day it does not matter what the format is, as the intention is to get some

agreement and an understanding should ex-ist upfront. It should be understood and then

signed well upfront.Should the employee not be fluent in English for example, then ensure the process and issues are explained by the use of an interpreter.

Local demand for simulator training is being driven by key factors that include health and safety legislation, improved machine utilisation, and pro-duction tonnage demands.The first Cat simulator introduced locally by Bar-loworld Equipment’s Operator Training Academy was a dedicated Version I unit designed for the new M-Series motor grader line-up launched some three years ago. Including M-Series graders, this latest generation Ver-sion II simulator product line will cover small wheel loaders; large wheel loaders; large mining trucks; track-type tractors (based on the Cat D8 model, but applicable up to and including the top of the range Cat D11T, covering both construction and mining applications); and medium sized hydraulic excavators (based on the Cat 330 model).

Real-lifeLearning

Featuring the very latest tech-nology, they are designed to make the training experi-ence as realistic as pos-sible. Examples include a ‘motion’ sensor tracking device, which is worn on the operator’s head. Depending on the ma-chine programme, as the operator’s head moves

during simulated training, so too does the site image

on the computer screen panel, shifting to the left or right, up or down via ‘on board’ machine camera systems. On the dozer simulator station, for example, there is a front and rear screen panel showing a forward and rear view since opera-tors need to look back when they’re ripping.Every user has his or her own log-in ID and the system records individual operator performance.Parameters can also be built into the system and adjusted to match customer sites and equipment fleets. For example, in the large wheel loader simula-tor model, an operator might be required to load a Cat 777 90 tonne payload truck within a 30 second cycle time.

In the event of a fire, Legrand fire-man’s emergency switches enable easy disconnection to the mains from outside a building, quickly and ef-fectively, at no risk to the user. These weatherproof emergency switches ensure the power supply to high volt-age signage is completely isolated by the fire chief, from outside the building in a crisis situation.For enhanced safety, an automatic locking device in the ‘OFF’ position

prevents accidental switching on and destructive tampering. A device also prevents the box from being opened when in the ‘on’ position. These unob-trusive switches are usually positioned at a height of 2.75 m for easy accessibility for firemen who have to switch off the sign should an electrical hazard arise. IP65 – IK 08 is the standard index of protection, which means these switches are shielded from dust and water. The box of the switch is manufactured from highly resistant plastic, making it suitable for use even in corrosive environments.Legrand SA, Tel: (011) 444-7971, Email: [email protected], www.legrand.co.za

Although the construction industry has largely remained static for the past two years, growth in office, retail and other non residential construction has been negative, while the residential housing market is expected to increase by just two percent during 2012. Corobrik remains resilient and is looking to the launch of new products and growth in the afford-able housing sector to maintain its strong performance. Dirk Meyer, managing director of Coro-brik, says “Over the past 20 years, the low cost and affordable housing mar-kets have been dominated by cement based products. We stand to benefit from diversifying and launching new products such as the CoroJem and PlasterJem which are not only competitive during initial construction but provide longer term benefits such as durability, low mainte-nance costs and lower energy consumption.” During 2012, these products accounted for more than 20 percent of Corobrik’s sales with plenty of

Makita have recently added the TM3000CX2 Multi Tool to their product range. It produces from 6,000 to 20,000 oscillations per minute, and has a variable speed control dial and a soft start, which allows for accurate landing of the blade on the surface of the

Multi Tool

work piece. It has 12 angle settings from 0 degrees to 360 degrees at 30 degree intervals, which allows for a wide range of applications.The TM3000CX2 barrel grip has been designed to suit many different ways to grip the tool for different applications utilising a wide range of accessories. The Makita Multi Tool is supplied with the Two-segmented saw blades, which are suitable for cutting vari-ous materials such as wood, dry walling, plastics, copper pipes and non-hardened nails. The benefit of this type of blade is the allowance for long distance push cutting as well as flush-cutting on the edge of materials and in corners.Four-plunge-cutting saw blades make this tool suitable for cutting wood, hardwood and metal for a deep plunge cut or for flush cutting of nails or plasterboard. The blade can be positioned in twelve different angles to allow easy operation in tight spaces.The tool features a flexible scraper

that has a low profile blade with a narrow tip, which is ideal for removing window putty, caulking, etc or scraping paint.Rutherford – Makita, Robert Cameron-Smith, Tel: (011) 878-2600, www.makita.co.za

Growth in Affordable Housing Sectorpotential for further growth. Dirk points out that conventional clay bricks have already proved their worth both in the suburban residential market and in the building of hospitals, schools and shopping centres. Clay brick combines low upkeep with a “desirability factor” and status, which is important for first time property investors who want their homes to stand out from basic low cost housing. He adds that the move to sustainable building across all segments of the market was already working in Corobrik’s favour. “Brick is more sustainable than most other building materials. It not only lasts far longer than other building materials, but is also

re-useable and recyclable. It is also the most energy efficient option with at least 10 different local and international studies demonstrating that clay brick structures are cooler during summer and warmer during winter, significantly reducing the need for artificial heating and cooling.Corobrik, Dirk Meyer, Tel: (031) 560-3111, www.corobrik.co.za

Joint damage in industrial floors accounts for about 80% of general floor deterioration and contributes more to floor problems than cracks. However, joints in floor slabs are unavoidable and all joints require some form of load transfer and elimination of vertical movement.

Keeping Floors in ShapeKeeping Floors in ShapeConventional methods of load transfer such as key-way joints or round dowel bars have been known to cause long term problems. The patented Diamond Dowel System from Norton Construction Products has revolutionised the design and construction of load transfer across construction joints.The Diamond Dowel System offers technical ben-efits, as well as simple and accurate installation. The diamond shaped load plate has been proven to be the most efficient and economical way of achieving load transfer in construction joints. To install the system the contractor simply uses a three way component system comprising a pocket former sleeve, a formwork connecting base and the steel plate. The formwork base and sleeve are attached to the formwork and the concrete is cast as normal. Once the forms (and base) are removed the plate can be inserted into the remaining pocket former sleeve ready for the second slab cast. The inherent simplicity of this method reduces both the material and labour costs.

"DPI Plastics has been manufacturing uPVC gutters and downpipes for more than 30 years, and we have developed a specialised formulation that ensures excellent impact strength that can withstand severe weather," says DPI Plas-tics technical and prod-uct manager, Renier Snyman.What's more, Renier high-lights the fact that DPI Plastics installed Rainflo gutters and downpipes

at its head office in Roodekop, Germiston, more than ten years ago as part of the company's com-mitment to testing its own products first-hand in the hail belt of Gauteng.

"In addition to surviving the numerous storms that are typical of Gauteng's climate, the Rainflo gut-ters and downpipe located onsite at DPI Plastics' headquarters have also not cracked or turned yellow as a result of UV exposure, thanks to a com-bination of UV stabilisers that are included during the manufacturing process. This has resulted in the company providing a ten year UV guarantee on all Rainflo uPVC products," he continues. Renier adds that uPVC Rainflo gutters and downpipes have proven to be particularly popular along the coastal regions of South Africa, due to the excellent corrosion resistant properties of uPVC. "Steel gutters and downpipe are prone to rust in coastal regions, and Rainflo serves as the ideal replacement system, as uPVC is entirely rust proof."DPI Plastics, Martine Goodchild, Tel: (021) 957-5600, Email: [email protected]

Dowson and Dobson director Terry O'Kelly points out that the company stocks a wide range of M7 air-operated tools, including; impact wrenches, ratchets, air die grinders, angle grinders, sanders, drills, screwdrivers and hammers."M7 air tools are more cost effective than their electric counterparts, in addition to having a higher power-to-weight ratio. This is a result of the use of modern lightweight mate-rial in the manufacturing process.

The primary advantage of the M7 range of air tools is that they are not powered by electric motors - making them lighter and more manoeuvrable than electric tools. M7 air tools also reduce costs related to energy consumption, which is a major advantage in South Africa, where electricity prices have risen substantially in recent years," he explains. M7 air tools have proven to be popular in industrial projects for a number of years. "The portability and versatility of these tools has made them particularly popular in local manufacturing applications for 5 years. "

Terry notes that the M7 brand is synonymous with quality. "M7 tools are reliable, efficient and tough enough to simplify even the most challenging jobs. What's more, all M7 products have international ISO and CE certification, thereby providing the user with complete peace-of-mind."

The South African division of international engineering consultancy firm SMEC has played an instrumental role in the rehabilitation and upgrade of the R55 dual carriageway in Tshwane, which was officially opened to motorists on November 22, 2012. After successfully completing the R200-million Phase 1 section of the project in November 2010, which entailed the construction of a dual carriageway between the N14 freeway and Wierda Road, SMEC South Africa was immediately appointed as the project management consultant for Phase 2 of the infrastructure upgrade project undertaken by the Gauteng Provincial Government.This project involved more than R228-million worth of upgrading and rehabilitation work to the 4,2 km section of the R55 carriageway from Sunderland Ridge to Laudium, which is a major arterial road between Johannesburg and Pretoria, which also connects the region to the N14 freeway. SMEC South Africa technical director Tshepo Matshego explains that the company's scope of work included the upgrade of the road from a single carriageway to a dual carriageway, and the construction of two bridges over the Hennops River. To improve safety and night-time visibility, 10 km of street lighting was installed over the full length of the road, from the N14 interchange into Laudium. Commenting at the official opening of the new R55 dual carriageway in November 2012, Gauteng MEC for Roads and Transport Ismail Vadi hailed the project as an overwhelming success. “The success-ful and timely completion of this dual carriageway ensures that road users are provided with a safe and quality alternative route to the Ben Schoeman freeway, which often sees heavy traffic volumes. I thank all contractors for the quality of the road, and it's timeous delivery."In addition to creating a more advanced and ef-

ficient road network for motorists, Tshepo points out that Phase 2 of the R55 upgrade project also generated skills development within the surround-ing community, with more than 150 local jobs being created as a direct result of the project. "All of the locally-employed contractors received full training and certificates of qualification in their respective fields, which will go a long way in ensuring that they are better equipped for future employment."Looking to the future, Ismail announced at the open-ing ceremony that the remaining sections of the R55 between Main Road in Laudium and Maunde Street in Atteridgeville would be scheduled for rehabilita-tion in the next financial year at an estimated cost of R50 million.SMEC South Africa, Tshepo Matshego, Tel: (012) 481-3810, Email: [email protected]

The urgently needed second phase of the Western aqueduct pipeline is underway once again. Neil Macleod, head of eThekwini Water and Sani-tation (EWS) says bids have been received for the first sector of the pipeline project, and the second sector will also be released for tendering at the beginning of 2013. EWS has unbundled the 55km pipeline project into six individual projects which will be rolled out over a seven-year period. The seven kilometre long first sector, valued at approximately R125 million, will stretch from Inchanga Station to Alverstone Neck. The second, which begins at Alverstone Neck and has a similar value, will end at Ashley Drive in Kloof.

Construction is expected to begin during the first quarter of 2013. EWS had called for expressions of interest from the contracting fraternity and has selected 16 contractors to form two panels – one made up of companies qualified to deal with large diameter pipes and one comprising companies that are able to work with pipes of smaller diameters. The entire 55km second phase begins at Inchanga Station and ends at Ntuzuma and includes two branch pipelines to Tshelimnyama and Mount Moriah. It is expected to significantly strengthen the capacity of bulk water supply to the western regions of eThe-kwini, injecting up to 400Ml/day. At the same time, it will ultimately boost much needed water supplies to the north of Durban. Western Aqueduct Project, westernaqueduct.durban.gov.za

Deciding on a Heat Pump For Residential UseDefinition: A heat pump is a well engineered compact system that heats water efficiently using electricity.

What does it look like?A small airconditioning unit (50 kg) mounted outside on a wall. Your geyser stays where it is. The unit and geyser are joined with water pipes.

Can it be installed inside, or in the roof?No. It needs a continuous source of ambient air, so it must be outside.

Does it replace a geyser?No. It heats the geyser water. You still need the water stored in a geyser.

How is the geyser water heated?Cold water is pumped from your geyser through water pipes into the heat pump unit, and returns to the geyser hotter than it went in. This continues until all the geyser water has risen to the set geyser temperature of 50-55 °C.

How much electricity does it save?A well-installed and set heat pump can save 60% and more of your electrical element costs. The more you are using currently, the more you will save.

When does it save most?When the air outside is hot.

When does it save least?When the air outside is cold. If you can wait for the air outside to heat up, you will save more.

A comparison between an electrical resistance element and a heat pump A geyser is simply an insulated hot water tank. The water within the geyser can be warmed in three ways:

using an electrical resistance element, using a heat pump, or using a solar collector. The purpose of this article is to compare two of these technologies – the electrical resistance element and the heat pump.The major difference between these two technolo-gies is that an element uses electricity to create heat, while a heat pump uses electricity to move heat. All things being equal, it is far more efficient to move heat (heat pump technology), than to create heat (element technology), which is why investing in a heat pump makes financial sense.

Continuous cycleThe cold refrigerant liquid and gas mixture enters the evaporator. The air blown by the fan over the evaporator causes the refrigerant to gain heat energy from the air. This boils the refrigerant, changing it from liquid to gas, and continues to add heat to the gas. The gas absorbs heat from the air and is com-pressed, a process which raises its temperature further. The refrigerant – now in a hot, high-pressure gaseous form – is then moved through the sys-tem to the heat exchanger. Here, the water absorbs the heat energy, and the refrigerant loses heat energy.The water pump feeds cold water into one side of the heat exchanger, and the water is heated typically by about 5°C, to return to the geyser. Now being cooler, the refrigerant becomes liquid again, though still at a high pressure. The high pressure liquid passes through the ex-pansion valve, changing to a low temperature, low pressure liquid and vapour mixture.

In much the same way as the parts of an air con-ditioner are contained in a ‘box’, so too are the parts of a heat pump. These include an electric fan, a small electric gas compressor and a small electric water pump, an evaporator, an expansion valve and a heat exchanger, and of course, the refrigerant that changes from liquid to gas and back again in a continuous cycle.

HOW TO


Heat pump tank size Rebate is offered as follows:

301 – 500 litres R4,320

100 – 300 litres R 3,668

An electrical resistance element is very basic tech-nology. When it is fitted inside a geyser, the heat it generates is transferred from the element to the water. It is also very light (about 300 g), relatively cheap (±R150) and readily available. All these factors mean that, should it stop working, it can be easily repaired by just one person, typically a plumber, with minimum fuss.By contrast, a heat pump – or more cor-rectly, a heat pump system – uses smart engineering to warm water by transfer-ring heat from the air into the water in the geyser. This is achieved by moving a refrigerant in a continuous cycle that boils and condenses it. Boiling the refrigerant absorbs the heat from the air, condensing it transfers the heat into the water. This is possible because the refrigerant has a lower boiling point than air.This refrigerant has a far lower boiling temperature than water, which means that it changes from a liquid into a gas far more readily than water does, making it a far more efficient heat energy ‘col-lector’. The closer the heat pump to the geyser, the more effective the system.Because a heat pump is a system and weighs about 60 kgs, installations and maintenance is more complex than for an electrical resistive element. It can, however, be installed by a team comprising an electrician and a plumber; repairs are typically carried out by an air-conditioning technician.

A heat pump costs around R15 000 before the rebate. However, because it is so efficient, it can shave up

to 70% off the costs of heating water using an element.Many of today’s heat pumps operate us-ing environmentally-friendly refrigerants such as R407, R417 and R134, further enhancing the tech-nology’s appeal as a ‘greener’ alternative to electricity-driven element-heated wa-ter.

Savings Using a heat pump will immediately re-

duce your electricity usage and provide a return on your investment. For example, heating 200 litres of water per day costs just under R14 per day using an element, and less than R5 per day using a heat pump. The graph below shows estimated costs of heating 200 litres of water per day over the next 8 years.

HOW TO

Is a heat pump better than solar water heating?Studies have shown that heat pumps are better suited for high hot water users, where the geyser may need reheating several times a day. Solar water heaters may be better suited to single family houses when the hot water usage is generally the same time each day.Ideally we should use solar water heating, with the backup heating done with a heat pump.Eskom Heat Pump Rebates, www.eskomidm.co.za/heat-pumps
