Moladi reduces high costs of conventional building techniques through new technology

Reducing the cost of affordable housing

Addressing the housing shortage: If the "horse and carriage" transport system is to slow getting people from A to B then it's time for the "Model T" to come to the rescue.

"We can't solve problems by using the same kind of thinking we used when we created them." - Albert Einstein. Old technology has created the backlog - new technology can solve the problem.

Albert Einstein also said “Insanity: doing the same thing over and over again and expecting different results.”

Is it not time for change?

Africa is a rapidly urbanising continent, which according to the UN Habitat, is increasing at a rate of 230,000 people who are moving into cities across Africa each week. Currently, sub-Saharan Africa alone has an estimated housing deficit of 30 million units and every year, the backlog of houses across Africa’s 54 countries collectively increases by 4 million houses. With the population of the African continent expected to reach a staggering 2 billion people by 2050, almost twice the population number estimated in 2010, it is a stark reality that every year, there will be more and more people needing homes, over and above the current demand.

There is no doubt that the challenge facing the continent is a colossus, but the question is, whether conventional building methods are able to cope with the ever-increasing demand for quality homes.

reduce cost of construction

Throughout history, man has become more sophisticated through technology; made improvements on existing standards and norms, which have ultimately been determined and developed according to the needs of the people. Perhaps the advances and progresses in communication and transportation during the past two centuries are the most evident of such improvement enjoyed by civilization. However, even though the need for housing has always been a fundamental requirement to sustain one’s health and welfare, the advances in this area have been somewhat meagre in comparison. The brick and mortar method of construction was recorded as early as 1458 B.C, which means that very little has changed in terms of building structures over a period of almost 3.5 millennia. With the demand and requirement currently facing us as Africans, we cannot expect to resolve the housing crisis in our age with a technique developed for the requirements of society 3468 years ago.

affordable housing low cost

One such innovation is the award-winning Moladi Building System, which looks at incorporating green technology and sustainability to provide the best solution to address the six key challenges that hinder the successful implementation of low-cost housing projects in Africa; namely, lack of sufficient funds, shortage of skilled labourers, lack of resources, work flow control, time constraints and wastage. The Moladi construction system was founded in South Africa during 1986, and has been in successful operation for the past 31 years. Moladi’s founder and designer, Hennie Botes, developed the innovative building technology as a means to alleviate many of the cumbersome and costly aspects associated with conventional construction methods without compromising on the quality or integrity of the structure. According to Botes, “Moladi looks at what has to be achieved now and builds on the knowledge and expertise of yesterday in order to develop sound methods to exceed the needs and expectations of ordinary people.”

Need to build a house quickly? Or build a lot of houses quickly to shelter a growing population?

The moladi plastic mould formwork is filled with cement and sand, with plumbing, electricity, window, and door frames placed "between the formwork."

The shell of the house is ready overnight.

The Moladi building system involves the use of a unique removable, reusable, recyclable and lightweight plastic formwork mould which is filled with an aerated SABS (South African Bureau of Standards) approved mortar to form the wall structure of a house in only one day. The process involves the assembly of a temporary plastic formwork mould the size of the designed house with all the electrical services plumbing and steel reinforcing located within the wall structure which is then filled with a specially formulated mortar mix to form all the walls of the house simultaneously.

ABSA NHBRC AWARD

The result is a fast track cost effective and transferable construction technology that is amortized over 50 re-uses, which reduces the cost of construction and transportation significantly. This also facilitates the possibility for many in situ structures to be built in just one day. It is essentially the simplicity of its design and performance that contributes to the affordability of Moladi homes which are roughly 30% to 50% less than similar structures built using the traditional brick and mortar method.

Affordable homes cheap

The Moladi method of construction, using it's patented plastic formwork, has been designed to efficiently produce structures which have a long life, are durable and adaptable; homes which are considerate of the environmental impact as well as the needs of the home owner. The speed, affordability, quality, adaptability, ease of use, the use of sustainable local materials and the opportunity created to facilitate sweat equity are key advantages that would greatly improve the efficiency with which the world addresses the problems relating to the world’s poor, homeless and unskilled communities.

    Future-of-construction-moladi

    Creating low-cost housing and social infrastructure is a challenge across the globe. A project to create much-needed courthouses in Tanzania may have shown a way ahead.

    The Moladi construction system replaces the cumbersome bricklaying process with an approach akin to injection moulding. Workers erect the building’s frame with reusable plastic panels, leaving wall cavities which – once the windows, doors, wiring and pipework have been put in – are filled with a fast-setting, aerated mortar.

    The building process can be monitored by just one qualified supervisor who manages local workmen with no prior construction experience or skills.

    The first project, Kibaha District Courthouse, was built for $250 per square metre, which is half the cost of conventional methods. It took six months to complete when it might typically have taken up to three years using traditional methods. On the back of this success, the Tanzanian government has committed to building another 11 district courthouses using this method.

    Building the Future

    Relative to other industries, productivity in construction has stalled over the past 50 years. Technology was not making any fundamental advances, and companies remained averse to changing their traditional methods. Recently, however, transformative technological developments have emerged, and some pioneering firms have adopted them for current projects. These developments – moladi, 3D printing, building information modelling, wireless sensing and autonomous equipment, to name just a few – are already starting to turn traditional business models upside down.

    moladi - Future of Construction

    Strong population growth in many developing and emerging countries and mass urbanization – an estimated 40,000 people moving into African cities every day – create a strong demand for affordable housing. Beyond housing, many developing countries are lagging behind in access to social infrastructure and public services such as schools, hospitals or the justice system. Consider Tanzania: the country faces a shortage of 3,115 courtrooms.

    Moladi Construction System aims to address that magnificent challenge by providing a scalable, low-tech and low-skilled affordable building solution using in-situ casting. Founded in 1986 by South African social entrepreneur Hennie Botes, the company aims to replace the classic brick-and-mortar construction with an easier method: using lightweight, removable and re-usable plastic formwork that are filled with a patented fast setting aerated mortar to cast entire houses on-site. The process is deliberately designed to be labor intensive and mostly uses local supplies (apart from the reusable formwork and a special additive (MoladiChem) to boost local employment and local production without requiring prior construction experience.

    Train the unemployed to build for the homeless - Hennie Botes - Founder and CEO

    The main advantage of this affordable construction solution is its social acceptance – a challenge encountered by any affordable building project, especially if the solution is imported from abroad. In the case of Moladi, its integration into a wider effort to boost the community and the fact that people can knock on the cast walls to check for solidity – the sound is the same solid sound as traditional brick-and-mortar walls – helps to gain immediate approval. Gypsum-board walls for instance are regarded as less strong  and weather resistant. As a consequence, the solution has been applied in 20 countries in Africa (e.g. South Africa, Nigeria, Tanzania), South Asia (Sri Lanka) and Latin America (Mexico, for two-storey buildings and Panama) and the company is currently planning expansion into the United Kingdom.

    Due to its strong track record and advantages, the government of Tanzania has selected Moladi as the most cost-effective solution to address its courthouse shortages. A 1,200 square metres pilot project has been successfully completed – faster and cheaper than alternative solutions – and the courthouse was inaugurated by the Tanzania’s Prime Minister.

    Industrialized housing system

    The construction industry is undergoing a transitional change from an industry employing conventional technology to a more systematic and mechanized system. This new system is now known as the Industrialized Building System (IBS). This new method of construction can increase productivity and quality of work through the use of better construction machinery, equipment, materials and extensive pre-project planning. This study becomes very necessary since there is yet no organized body, which can provide the necessary information on the building cost comparison between the conventional system and industrialized building system in the construction industry. moladi plastic concrete formwork addresses the building cost comparison of the conventional system and industrialized building system of formwork system. It provides the details building cost between the conventional system and the formwork system and indicates which of the two is cheaper. The data were collected through questionnaire survey and case study, which consisting of institutional buildings. Through the statistical test it is shown that there is a significant difference in cost saving for the conventional system as compared to the formwork system (industrialized building system - IBS)

  • Insanity: doing the same thing over and over again and expecting different results

    "We can't solve problems by using the same kind of thinking we used when we created them." - Albert Einstein.

    The "Horse & Carriage" industry was becoming too slow and cumbersome getting people from A to B compared to the "Model T" - The "Model T" has "destroyed the "Horse & Carriage"  industry due to it's shortcomings and inherent drawbacks. 

    This process is called "Creative Destruction" or "Disruptive Innovation" - Embracing the new and letting go of the old.

    Brick and Mortar - Masonry

    brick evolution

    For more than 3,500 years bricks have been produced in a mould - When the bricks are de-moulded, some of them break. When the bricks are stacked to be fired, some of them break. When the bricks are unpacked from the stack, some of them break. When the bricks are loaded on to the truck, some of them break. When the bricks are transport to site, some of them break, When the bricks are offloaded, some of them break, When the bricks are wheelbarrowed to the bricklayer, some of them break. When the bricks are packed onto the scaffold, some of them break. When the bricklayer does beam filling, he breaks a brick to make it fit. Not really a "optimized" production process taking into consideration breakages along the way. Not to mention the stock theft on site.

     “If you can measure it, you can manage it.”

    By producing more bricks or blocks the problems of the "Horse & Carriage" industry would still not be solved...The bottleneck lies with the shortage of skilled artisans or bricklayers - not producing more bricks or blocks with expensive machines 

    Mass Production blocks

    In the delivery of affordable homes the production is governed by the capacity of people or skilled artisans or bricklayers to lay bricks. Then the wall is handed over to skilled artisans or plasterers This phase is where the bottleneck of production lies.

     

    Artisan bricklayer

    "A plasterer is a tradesman who works with plaster, such as forming a layer of plaster on an interior wall or plaster decorative moldings on ceilings or walls. The process of creating plasterwork, called plastering, has been used in building construction for centuries."

     

    The moladi plastic mould becomes the "brick plant" that produces an insitu monolithic reinforced structure on site (one big brick) in a day - Speed reduces cost - No waste - No skills - same material as the foundation without stone (mortar) Less logistics to manage - The "Model T" of housing
