ED’S NOTE
In-between
While we aspire, and work hard, to have decent affordable housing available for everyone, lament and try to mitigate the overwhelming backlog and despair at the conditions in which so many South Africans must live, we are often distanced from the reality of life without proper housing and the lengthy, often interminable, period between this and having a proper, decent place to call home.
T
hose liminal or in-between spaces are occupied by many, and although the construction and reconstruction of informal housing is wholly removed from what we, at the SA Affordable Housing magazine, wish to promote, the reality is that transitional housing can and does alleviate the suffering and indignity of those at the mercy of circumstance - and is hopefully just a temporary solution.
We also highlight an award-winning concept that offers a temporary housing solution in emergency situations. The article details that the Lantern “follows a simple, safe structure, in that the base and roof are constructed from metal profiles and natural recyclable materials, such as straw clay and mdf wood, for assured insulation, and the supporting structure consists of lateral metal profiles, based on the logic of an accordion.”
In this issue, we share two projects, one national, the other international, that address the most basic housing needs of people in or near crisis.
While we think about temporary living spaces in this issue, we also celebrate the many successes we have seen in the affordable housing market; beautiful projects, innovative property development and a sincere consideration for the communities involved, and hold these as prime examples of permanent housing that really works.
“Forgotten, but not helpless” on page 8 highlights the plight of a community practically living on waste disposal site under terrible conditions and how they have taken ownership over their own living conditions through the e-khaya project, “which aims to help communities to rebuild their shacks with a fireproof, flood-proof, insulated, quiet, attractive, durable, and cost-effective small house, designed to de a transitional or interim solution until permanent housing is available.”
We wish you a safe and happy holiday period and a prosperous year ahead. Welcome to the Nov/Dec issue of SA Affordable Housing. Enjoy the read! Jen

Changing the face of the cement industry Building our cement operations from the ground up has taught us more than just the technicalities of constructing a plant. It has entrenched a camaraderie in our people, a certainty that nothing would get in the way of us entering the market, writes Pieter Fourie, chief executive of Sephaku Cement.

A
s our Delmas cement plant comes online early in 2014 and Aganang in the North West becomes operational during the year, the face of the country’s cement industry will change, and there is no turning back. We have navigated our way through building leadership and operational teams from scratch, securing investors and safeguarding their investment, connecting with and involving communities, all the while designing and building the two plants. Our entry into the market is based on belief in the long term sustainable growth of cement. Our country may have relatively good infrastructure, but there is still a lot to be developed. Added to this, ageing production facilities have made production static at a time when it needs to be cost-efficiently increased. Great competitiveness and cost-efficiency lie in the state-of-the-art technology backing Sephaku Cement’s plants.

DETERMINED JOURNEY Our company, a 64% owned subsidiary of Dangote Cement plc and an associate company of JSE-listed Sephaku Holdings, was established in 2006. Sephaku Holdings secured limestone resources and invested the initial seed capital required for the project to get started. By late 2010, the projects were fully funded, having attracted the largest inward investment in South Africa by an African company, Dangote Cement. Through tenacity and determination, we navigated our way through the global recession, emerging with increased investment from Dangote Cement and backing from local market financial institutions, Nedbank and Standard Bank. With this heavyweight backing, the largest single cement plant in the country, our 6 000-ton-per-day clinker facility with a total cement capacity of 2.5 million tons per annum, is en route to being completed.

STRATEGIC DELMAS The construction of our 155-ton-per-hour cement milling plant in Delmas, Mpumalanga, is well on track to begin cement production early in 2014. Our operations here give us a distinct advantage. Not only are they close to Gauteng, but through efficiencies enabled by the latest technology equipment in this plant, we can secure a respectable share of the inland market. From a process perspective, our cement process, which begins in Lichtenburg, after which the clinker is transported to the Delmas milling plant, is more costeffective through transporting clinker rather than cement. In addition, our fly ash beneficiation plant at the Kendal Power Station, Emalahleni, adds to the economies of scale with our plant being just 35kms from Delmas.
COMMUNITY CONNECTION Since the early days of our journey to market, we have made a concerted effort to invest in areas where the needs of Verdwaal, Itsoseng and Springbokpan are supported. These communities are situated near our flagship plant and work done with the people here includes initiatives in education, employability, enterprise development and healthcare.
PEOPLE FOCUS Sephaku’s sales and customer service team is a cement force of experts. We want to ensure that every customer gets the best from our product. From the very beginning we will assist technically in designing mixes and selecting the optimal cement for customers’ requirements. We are also adding to value through support provided by our Sephaku Cement Technical Laboratory. Looking back over our six year journey we have overcome some serious challenges. But we have never lost belief in why we are coming to market or the definitive belief that we will enter this market. Success is the only option for us as we remain committed to making South Africa’s cement industry all about the needs of the people who make the end product a reality. Through taking a more hi-tech, progressive and passionate approach to the business of cement production, we will change the face of the industry. As Delmas becomes operational early in 2014, followed by Aganang, we look forward, with confidence, to the next steps of our journey. For more information, visit www.sephakucement.co.za.
We work closely with the leadership of these communities and have an open door approach to find out how we can help. This year has seen the company fund a Grade 10, 11 and 12 Winter School, which was hosted by the Tswelelopele High School in Itsoseng and attended by three additional High Schools. We are also setting up five small business initiatives in the transport, logistics and pallet sectors. NOVEMBER / DECEMBER 2013

TRANSITION HOUSING
Forgotten, but not helpless Intolerable living conditions in Faure informal settlement, Blue Downs, addressed by the community itself through e-khaya Project
T
he community living at the Faure informal settlement in Blue Downs is estimated to number approximately 50. It came into being following the closure of the Blue Downs waste disposal site more than a decade ago, where most had both lived and derived an income. Some individuals say that they have lived on the greater wastedisposal site for more than two decades and that the current location was temporarily allocated to them by the Oostenberg Municipality until permanent housing could be arranged. The majority are unemployed or continue to scrape an existence through the collection and sale of waste. Living conditions are dire. Shacks are dilapidated. The ground is visibly polluted and appears to be a stillaccessible extension of the adjacent waste site, now unused and surrounded by razor wire. There have been a number of shacks destroyed and injuries caused by recent fires and the presence of a high concentration of waste may be a factor in propagating these fires.

NOVEMBER / DECEMBER 2013
The health of the inhabitants has been acknowledged by relevant authorities to be very poor. It is very apparent to the casual visitor that the majority have severe and chronic health problems. Due to the extremely polluted environment, many children are apparently now living with relatives elsewhere. Most inhabitants have no identity documents and can therefore not access grants, apply for employment or a housing subsidy. Recent attempts to provide them with documentation have not, as yet, been successful. They are situated far from health and other services and cannot afford transport. Some toilet facilities have been provided, but there is just a single functioning water tap. That fellow citizens of our city continue to live in such appalling circumstances, and, in some cases, have done so for over two decades, is an indictment on all. This is truly the epitome of a forgotten and disenfranchised community.
TRANSITION HOUSING
FORGOTTEN BUT NOT HELPLESS With the assistance of SEEBO community trust and its director, Mr Raymond Mtati, they have started to dramatically improve their lot by ‘thinking out-of-the-box’. SEEBO encouraged the idea that they could replace their shacks with something safer, insulated, dry and fireproof. Mr Mtati introduced the ‘e-khaya Project’ to them, which aims to help communities to rebuild their shacks with a fireproof, flood-proof, insulated, quiet, attractive, durable, and cost-effective small house, designed to be a transitional or interim solution until permanent housing is available. e-khaya managed to raise enough funding for the community to build two adjacent e-khaya units for two disabled and partially sighted of their members. e-khaya homes have three features that are uniquely able to provide these qualities in a shack replacement situation: • a re-usable building jig or frame, meaning that almost no building skills are required • an arched, extremely strong, insulated, selfsupporting but low-cost roof that is easy and quick to make, and means the footprint of the home is doubled and can be used for incomegenerating activities, such as secure storage, food growing, rearing of chickens and sale of eggs, secure locating of solar panels for an internet cafe or a quiet homework centre, etc. • narrow sandbag walls that are thermally and acoustically insulating, durable, totally fireproof, inexpensive and easy to build

TRANSITION HOUSING
The e-khaya initiative is designed to not only provide transitional homes, but to create micro-business opportunities, through upskilling township entrepreneurs to own and rent out building frames and their own expertise, instructing people on how to self-build their homes. Income can be derived from renting out the roof space which, subject to further research, may support a second living level. The material cost for a single 14m² e-khaya module is approximately R8000. This means that it can be self-funded, and paid for in as little as three years, with no requirement for donor funding or government housing subsidies. This is a radical departure from the status quo. The goal is a home that improves health, quality of life, comfort, security, education, whilst reducing living costs, environmental impact, social dysfunction and violence. Not all residents in informal settlements across Cape Town will have such an urgent need for a solution to their current circumstances as those of Faure, but there will be many who do. And the ripples of what is learned together with the people of this forgotten Blue Downs waste site will travel across our city and beyond. Construction by the community of the first joint SEEBO/e-khaya home commenced in May of 2013 on the Old Faure Road. Sandbags were filled on a Monday, the re-usable frame was erected on the Tuesday morning, and the sandbag walls for the entire 28m² home were in place by the Thursday afternoon. Unfortunately, the project was threatened with demolition by the Department of Human Settlements on the Friday, and it has taken over two months and intervention by the Premier to resolve this.

TRANSITION HOUSING
The project is now complete and includes various simple sustainable technologies – rainwater harvesting, cold and solar heated running water, solar LED lighting, daylighting, biomass cooking and space-heating stove, and unbreakable polycarbonate security windows. Future projects will include a dry sanitation system. The manufacture of these simple systems will create micro-business opportunities in the community. This project has raised many questions around what shack-dwellers in informal settlements are permitted to do to improve their own living conditions. Some of these relate to land tenure, the definition of temporary versus permanent structures, types of materials that may be used, among other issues. The reality is that there are currently not many options to make a quantum leap in improving living conditions in informal settlements, at a cost that is realistic and that can perhaps even be self-financed. Various proposals have been put forward for small incremental improvements to shacks, but even these carry a high cost/benefit ratio. The SEEBO/e-khaya shack replacement project is a radical departure from the current situation of shack or RDP house and nothing ‘in-between.’ It aims to address the urgent and critical social crisis of urban slums, by empowering people to help themselves to improve their own living circumstances in the communities in which they currently live. It is morally unacceptable that people are prevented from doing so. And to gauge community acceptance of this type of home and construction, one only had to see and hear the reaction of passersby to the e-khaya exhibit, at the OpenDesign expo at the Cape Town City Hall until Tuesday 2 August. Not “When is the government going to give me one?” but “Fireproof and so solid. And as little as R10 000. I paid that for my wendy-house which burned down a year later. Where can I buy an e-khaya?” Now, that’s a mindshift of note. Madiba said in 1996 “The majority of the urban population live in appalling conditions far from their places of work.” SEEBO and e-khaya are striving together to change that.

SCHOOLS
First high school nearly complete at Bardale Villlage One of the much-awaited high schools at the successful Bardale Village development is nearing completion and it is anticipated that construction will be fully complete by January 2014.
T
he school will be ready for their first intake of students for January next year and it is expected that it will be able to accommodate approximately 800 students. “This new building is impressive: it has a modern, welldesigned aesthetic,” says Michael Bauer, managing director of the estate agency, IHPC. Following this development, said Bauer, it is anticipated that the government will be building another new high school and two new primary schools as they have already purchased the land.

NOVEMBER / DECEMBER 2013
They have now surveyed the sites, which could mean that they are in their planning phases for those schools, said Bauer. In addition to the primary and high schools, said Bauer, the new crèche facility (which will be run by a private operator), is also expected to be able to enrol its first intake of children in January 2014. They will be able to accommodate 140 children between the ages of two and grade R.
SCHOOLS
The first high school built at Bardale Village, which should be complete and ready for its first intake of students in January 2014.
“The fact that the overall plan for an integrated estate at Bardale Village is now falling into place bodes very well for property values here. The safe, family-orientated lifestyle that we have worked hard to create is now coming together and this will go towards increasing property values even further in the area.” “For many parents living here, knowing that their children can walk to school and will be inside the security estate and back home within a matter of minutes will make a huge difference and we believe this will make Bardale Village homes even more popular,” said Bauer. Demand for homes should increase here because of the schools being added to the infrastructure and, because this estate is geared towards family living, with homes ranging from two to four bedrooms, at prices from R455 000 to R745 000, families can find the space they need at affordable prices, said Bauer. “We have also found that banks have been approving more bonds recently and that there are more young professionals buying property at Bardale Village,” he said. “The family orientated lifestyle and the way that the buyers in the scheme have been controlled, have attributed to the success of the development. At present the majority of the occupants here are owners, there are only less than 25% owned by buy-to-let investors.”

OPINION PIECE
The three-headed city monster My wife and I missed our evening walk on Tuesday. I decided rather to attend a critical evening meeting at the Port Elizabeth St Georges club. I usually prefer to avoid evening meetings to do important family work and to ‘veg out’ on the couch with my dogs, but this meeting was different.
I
t was one in a sequence of meetings that report back on the work of an exciting grouping of business leaders volunteering their time to what they call ‘Project Nelson Mandela Bay.’ Under the direction of volunteers like Kobus Gerber, Michelle Brown and Andrew Barton, the project has, in very little time, identified a clear list of ‘doable’ projects that would turn this city and region around.
faceless authors of our public sector’s supply chain management procedure. The unavoidable net result of this strategy is a contested, completely unproductive standoff between the public sector ‘urban silo’ and the private sector ‘urban silo.’ No vision emerges and no leadership emerges.
They speak about plans for public access high speed wifi, they speak about a clean, green city, they speak about the freedom precinct and they speak about a full calendar events strategy; great ideas, great clarity and an impressive commitment that comes from the sincere passion of people that know that Nelson Mandela Bay is yet to live its finest hour.
In a similar way urbanists in the ‘academic silo’ come under increasing pressure to focus not on the South African urban crisis, but rather on purer academic pursuits. A 23-year-old with a PhD that deals with some arcane branch of architectural theory is much more likely to assume a professorship in architecture that a practitioner with 20 years’ experience in city building. This trend seems unstoppable with a momentum developed from the very pinnacle of our higher education community.
Sitting through the presentations in the Club’s grand and ornate colonial dining hall, I was reminded again that this city is not faced with a shortage of great ideas. It is not faced with a shortage of great individuals. It has incredible weather, no malaria, endless beaches, it is not in a warzone, nor is it a viable target for multi-national terrorists. So what are the obstacles? To be honest, I am not exactly sure, but with permission I would like to try out an argument to see if it resonates.
Architects who teach are now actively discouraged from participating in private practice. Those from private practice who give of their time and share their experience do so as volunteers. Academics offering to serve the public sectors are treated the same as their private sector counterparts, as a commodity to be bought through a ‘procurement system’ with the same resultant frustrations. In this way the silos grow increasingly isolated and positions within them become more and more entrenched.
My argument is that the most significant obstacle to meaningful spatial transformation of South African cities lies not in a shortage of academic ‘know-how,’ public sector investment, or private sector mobilisation, but rather, it lies in the entrenched, dysfunctional relationship between the public, private and academic sectors. Each of these sectors operates increasingly as a silo, separate from the next, with no mechanisms available for true collaboration.
Urbanists, of otherwise impeccable credentials, begin to withdraw into cynicism and isolation. Great ideas are shelved, big visions parked and energy diverted.
The public sector has become driven by a number of imperatives that require it to ‘procure’ the ‘services’ offered by the private sector in a standardised procedure designed to procure anything from light bulbs to toilet cleaning contracts. The obvious fact that public and private sectors can best serve the urban crisis by contributing the best and brightest from their ranks to collaborate in providing, vision, leadership and direction is of no concern to the
18
NOVEMBER / DECEMBER 2013
The sorry fact is that no workable protocol exists that enables top urbanists from the public, private and academic sectors to collaborate and share thinking on the spatial transformation. Instead we have developed the unsubstantiated and unscientific belief that a formalised, project level ‘public participation’ process will magically and miraculously manifest the big ideas we know are waiting to turn our cities around. Well, it hasn’t and it won’t. In the world of city building I am afraid public participation amounts to no more than a series of noisy meetings in stuffy halls where the housewives, car guards and estate agents clamber for the microphone drowning out the voice of any academic or private sector urbanist with real value to add.
OPINION PIECE
Yes, it’s democratic. Everyone gets a say. But that does not mean that we are harvesting the best ideas from the minds of the few that are excellently placed to take us forward. There is no meaningful collaboration, so we stay where we are – and where is that? Is there any solution? Is there any alternative to these dysfunctional relationships? Is there any way out of the urban crisis, defined by the geospatial legacy of apartheid and entrenched by class and poverty hurdles? Of course there is. These challenges were made by people. And they can be overcome by people. It’s up to us to develop new protocols and to have the courage as activists, in whichever silo we sit, to do whatever it takes to push them through, to confront our management, to put ourselves at risk. The re-shaped cities of the future depend on our action.

EMERGENCY HOUSING
Lantern shelter
Emergency housing for refugees Architects, Valia Panagiotou and George Pappas, have won the 3rd International Award for Young Architects (May 2013) as part of their participation in the International Competition of Young Architects Temporary Sheltering Spaces , with the subject Shelter for Refugees ‘Lantern.’
T
he competition was launched by the International Union of Architects (UIA) in collaboration with the Technical Chamber of Turkey, and the presentation and exhibition done during the 8th Conference of New Architecture, held in Antalya (Turkey). International refugees are as a result of war, poverty, hunger, and uncertainty, which ultimately lead to migration. The majority of international refugees flock to the countries of South and Eastern Mediterranean. The proposed project has the main objective of creating a temporary dwelling unit or cell, able to accommodate a fourmember refugee family, whilst covering basic living needs. A combination of a few of these units will form structures such as health facilities or schools.

EMERGENCY HOUSING
The Lantern is 14.50m² and is used as a shelter in emergencies. It follows a simple, safe structure, in that the base and roof are constructed from metal profiles and natural recyclable materials, such as straw clay and mdf wood, for assured insulation, and the supporting structure consists of lateral metal profiles, based on the logic of an accordion. The interior is isolated from the external environment by way of a double-façade polypropylene skin, translucent in nature, which offers natural sunlight, while the ‘phenomenon of the chimney’ offers natural air-conditioning. In following an alternative design methodology for temporary housing, Lantern proves to be a cost-effective and viable prototype emergency shelter for war refugees in the Middle East. This is reflected in the materials, construction, assembly, transportation and flexibility of the structure.

CEMENT & CONCRETE
Tilt-up construction for costeffective aesthetics and durability Gary Theodosiou, engineer and lecturer at The Concrete Institute, says tilt-up construction is often overlooked in the design of structures, but can be one of concrete’s most cost-effective building techniques.
C
oncrete has an advantage over other building materials in that concrete elements can be constructed to accommodate specific applications. Tilt-up construction is a concrete building and construction technique where the elements are cast on site and lifted into their final position, maximising many of the unique and sustainable benefits of concrete for a costeffective building technique and efficient construction method.
This allows the cast element to separate from the casting surface once it has cured. This is a critical step, as improper chemical selection or application will prevent the lifting of the panels, and may entail costly demolition and rework.
Elements that are to be tilted up are formed on a concrete slab, usually the building floor, but sometimes a temporary concrete casting surface near the building footprint. After the concrete has cured, the elements are tilted from horizontal to vertical with a crane and braced into position until the remaining building structural components (roofs, intermediate floors and walls) are secured. By forming the concrete elements on the ground as opposed to the final position, tilt up provides a convenient construction method, saving time, man-hours and formwork.
Concrete is then placed, filling the desired thickness and surrounding all steel inserts, embedded features and reinforcement. The forms are removed when the concrete is cured, rigging is attached and a crane tilts the panel or lifts the element into place. In circumstances when space is at a premium, concrete elements can be cast one on top of the other, or stack cast. Quite often, a separate casting pad is poured for this purpose and removed when the panels are erected.
Conventional tilt-up panels are structural elements within a building that span from base to roof diaphragm, acting as beams and capable of carrying roof and slab loads. They combine the building envelope (façade), structure and final finish in one operation. Panels are set out in accordance with a predetermined casting layout drawing. Ideally, panels are cast on the surface bed of the project or on final concrete hardstand areas around the building.
A reinforcement grid is constructed inside the forms, after the form release is applied, spaced off the casting surface to the desired distance with plastic ‘chairs.’
Cranes are used to tilt the concrete elements from the casting slab to a vertical position. The slabs are then most often set onto a foundation and secured with braces until the structural steel and the roof diaphragm are in place.
CONSTRUCTION:
Tilt up does not sacrifice quality for cost – instead it provides a finished product superior to most other alternatives, as it offers the strength and durability of reinforced concrete walls while simultaneously being able to economically achieve aesthetic effects neither possible nor cost-effective with other methods of construction. The end-result is attractive, aesthetically pleasing buildings.
Once the pad (casting surface or floor slab) has cured, forms are built on top. A high quality plywood or fibre board with at least one smooth face is typically used, but aluminum or steel forms can also be used. Carpenters work off engineered drawings designed for each panel or element to construct on site, incorporating all door and window openings, as well as architectural features and other desired shapes that can be moulded into the concrete. Studs, gussets and attachment plates are located within the form for embedding in the concrete. The forms are usually anchored to the casting surface with masonry nails to prevent damage to the floor slab. Next, a chemically reactive bond-breaker is sprayed on the forms and casting surfaces to prevent the cast concrete from bonding with the slab.
Concrete elements are cast on site and lifted into their final position when the tilt-up construction method is used.

WATER RETICULATION
DPI Plastics to launch PVC-M
couplings in larger diameter options DPI Plastics ďż˝ a leading manufacturer of water reticulation, drainage and pipe-fitting systems in South Africa ďż˝ is introducing larger diameter Ultralok PVC-M couplings to the local civils and mining sectors, following the continued success of its current range.
U
ltralok, which is currently available in 110mm and 105mm diameters, is a first-of-its-kind patented product for the jointing of plain ended pipes. The existing Ultralok offering has proven to be highly popular in mining and civils applications, thereby prompting DPI Plastics to expand the range. DPI Plastics technical product manager, Renier Snyman, points out that the company plans to launch the 155mm and 160mm Ultralok variants to the local market by November 2013 and the 200mm and 210mm variants by May 2014. "Ultralok is ideal for repair couplings or primary joints in mining and civil pressure pipelines, due to the fact that it can be used with high-pressure PVC or HDPE pipelines up to 16 bar." Snyman indicates that DPI Plastics originally developed the Ultralok PVC-M coupling in mid-2012 in response to requests from its clients in the mining industry who were experiencing substantial and costly damage to their metal pipelines as a result of sulphate reducing bacteria (SRB) in the water. "When the metal pipes are exposed to sulphatecontaining water, the interaction of water and metal creates a layer of molecular hydrogen on the metal surface. SRB then oxidise the hydrogen while creating hydrogen sulphide, which causes severe corrosion," he explains. Snyman highlights the fact that the Ultralok system is fully protected against corrosion. "The lightweight, highstrength, low reactivity and corrosion resistance of PVC as a material makes it far better suited to heavy-duty and highly-abrasive mining applications." According to Snyman, the design mechanism of Ultralok is unique in terms of its robustness and gripping nature. "The body is manufactured from high-impact PVC, incorporating a unique pressure-enhancing rubber seal. As the pressure increases, the design of the seal facilitates a distributed load, thereby alleviating the tensile load on the body of the coupling." Ultralok is manufactured in-house by Johannesburg-based DPI Plastics, and is performance tested to the company's

stringent internal specifications to meet all criteria for use in 16 bar pressure pipelines where fully restrained joints are required. As a result, the Ultralok PVC-M range has successfully met the following test criteria for the SANS 1283 specification: one-hour test at 54,50 bar, ten-hour test at 50,60 bar, 100-hour test at 45,50 bar and the 1 000-hour test at 16 bar at 60°C. Although Ultralok has been used predominantly in mining applications to date, Snyman states that the product is gaining ground in the civils market, and he is confident that the extended range of larger diameter couplings will lead to increased sales in this sector. "We have sold a substantial number of Ultralok couplings, particularly for use in new potable water reticulation pipelines. As more money is invested in larger pipeline projects, I believe that the demand for the new diameter couplings will increase substantially in the long-term," he adds. Looking to the future, Snyman notes that DPI Plastics will be promoting the benefits of the new Ultralok range through various tradeshows, publications and industry word-of-mouth. "The market is currently looking stable, and the promotion of DPI Plastics' proven quality and reliability will contribute significantly towards sustaining future market share," he concludes.
