Baseload May Not be Base Load

Posted By Rudzani Tshitahe, Pr. Eng, MSAIMechE, Thursday, 07 March 2024

Baseload electrical energy is, for the purpose of this article, energy that is readily dispatchable at a predictable energy availability factor level (EAF). The primary energy that enables dispatchability and predictable EAF are nuclear and fossil fuel.  The most compelling aspect of baseload that need consideration is that, power generation must be relatively continuous. Baseload therefore means electrical energy source that can be completely relied upon.

How about solar and hydroelectricity

Solar

Solar energy is used in two different forms as a source of primary energy, viz: (i) solar photovoltaic and rechargeable battery and inverter system; and (ii) concentrated solar and turbo-generator system. In these formats, Solar Energy does not meet baseload requirements as per the above-mentioned definition. During the period when the sun’s radiative intensity is lower than required, concentrated solar is unable to heat the working fluid to desired temperature levels or when the sun emits higher than required radiative intensity and photovoltaic cells lose their overall efficiency.

The intensive study on solar rays’ physical behaviour has yielded Improvements on these solar-oriented system.  Recent designs and application of heat storage systems have allowed for the storage of useful heat over an extended period of time and photovoltaic cells are now being designed and built to withstand beyond design-base heat intensity.  Photovoltaic is inefficient and require large space (agriculturally productive tracks of land could be lost to this technology) for small energy output, also then photovoltaic’s operational life is notoriously short. Soon solar will be engineered to meet the baseload requirements as defined above.

Hydroelectricity

A dam built across a river and a pumped-storage reservoirs with associated penstocks and turbo-generator arrangement can generate hydroelectricity.  In both cases, the amount of hydro-electric power generated is inversely proportional to the hydraulic head of the source. South African hydroelectric systems suffer low EAF as the seasons change from rainy to dry. The pumped storage system has an added disadvantage as its availability is already compromised due to necessary pauses between generating and pumping water back into reservoirs. Hydroelectric generation is therefore not a suitable baseload system (as per this article’s definition) for South Africa due to the fact that the South African river systems in unsteady and unreliable.

Grid stability issues

Even if PV solar, wind and battery energy technologies succeed at providing most of the energy required and they significantly surpass electrical energy generated by synchronous generating machines, a new problem would ensue. These inverters are not capable of keeping the grid stable, safe and efficient. The grid stability is defined as the grid’s ability to remain at the specific frequency and voltage levels.

The inverters in renewable energy generators mentioned above do not have capabilities to prevent the inertia shortfall, unless if further investment is made into equipment such as the synchronous condensers. The synchronous condensers emulate the synchronous turbo-generators in keeping the grid stable, safe and efficient.

Conclusion and necessary forward

A diverse baseload energy generating portfolio that includes renewables and aims to reduce adverse environmental impacts and associated externalities is essential for driving the country’s economy. As has been indicated herein, nuclear energy is an obvious choice for such a baseload portfolio. The other energy sources that must be explored and evaluated for the South African baseload is a geothermal energy source.

Sourdough Engineering

Posted By Vaughan Rimbault, Monday, 31 October 2022

A few months ago my son suggested we learn to make sourdough bread as a joint exercise. Sourdough is considered to be the original leavened or risen bread, using natural yeasts and bacteria in the flour to produce the rise and flavour of the bread. Home-made sourdough bread is very much a hands-on, artisanal process, and as we both enjoy learning new skills, this seemed like fun.  

Neither of us had any significant baking experience, so this would be learning something basically as complete beginners. We also live a considerable distance apart, so our experiences would be remote from each other, shared via chats and the exchanges of photos and videos.  

Less confusion and frustration

After much “blood, sweat and tears” I can now consistently produce a loaf which tastes as good as it looks.  I’m certainly no master-baker, but what I produce satisfies my needs and gets good reviews from family and friends. I was reflecting on the process of learning this new skill when it struck me that learning a professional engineering skill and learning a skill like bread-making were very similar at some level. 

To acquire any skill in as little time as possible you need three things: information; practice; and mentorship – and of those mentorship has the biggest impact on how well you handle the other two. That’s not to say that you can’t learn new skills on your own with only information and practice – it’s just that effective mentorship can speed up the process considerably, saving you time, effort, confusion and frustration.  This applies as much to making sourdough bread as it does to professional engineering practice.

Information overload

Back to baking. There is no shortage of information on the internet about making sourdough bread – just try your favourite search engine or social media platform. Many good people with the best intentions have uploaded content, but the information overload makes it all quite confusing. Everyone has their own variations at certain parts of the process, and it’s difficult to get a big picture of the process in the midst of all the detail. You can’t be sure which is important, and so you take a deep dive into the topic and find yourself swallowed up by the information. 

Effectively managing large quantities of information is a skill that is very necessary nowadays, where quantity often trumps quality. You need a guide through the ocean of text, pictures and videos that confront the newcomer – a friendly, wise adviser – a mentor. Having a mentor steer you is invaluable, as they can help you to focus on the specific direction that is required, and not waste time gathering useless information. 

Stretching and folding

My son (who was already baking at this stage!) was an unexpected mentor during my first steps into sourdough bread. He helped to focus my attention on the information that I was watching and reading so that I started to gather the data into understandable processes and not just a series of confusing steps.

With a better idea of what was required, it was time to try my hand. Mixing all the ingredients was simple enough, but the delicate art of forming strength in the dough by stretching and folding was where the wheels started to come off in a serious way. While this was clearly demonstrated in most videos and seemed simple enough, it was another thing entirely to get it right myself. No matter how much I practised I was still struggling with a sticky, gooey mess that attached itself to everything – the walls, the toaster, the kitchen window, and of course myself.  

First-hand advice

Practising the wrong thing over and over will never lead to success, and there was just something wrong with what I was doing. What I needed was someone to stand next to me and show me what to do. I plucked up the courage to ask a local baker for his advice, and was grateful that he was very happy to share his knowledge and experience. After a relatively short discussion and demonstration, and a few practises on my part, he offered some comments on my technique and showed me a few tricks. Problem solved.  

It still took some practice to handle the dough properly (the nuances thereof take years to truly master), but at least my practice was correct and it was just a matter of time before I got the hang of things. Again, my progress in learning this skill only really took place under the guidance of a mentor, and I would have saved a lot of time and frustration had I visited him sooner.  

Mentorship, mentorship, mentorship

The importance of mentorship came through clearly from this learning experience with sourdough bread, and it’s the same in engineering (with less yeast of course). We all take pride in sorting things out ourselves, but someone with knowledge and experience can ease the steep learning curve we would otherwise have to overcome alone. 

A mentor can guide you in what information is important (and what is irrelevant), and how to handle that information.  A mentor can show you how to do things properly, and can then watch you doing the tasks to make sure you do them correctly. Whether it is professional engineering skills or baking bread, a mentor adds significant value to the learning process. I would definitely recommend seeking out a good, respected mentor in your chosen field of professional engineering sooner rather than later.

On-site Machining

Posted By Nkosana Ncaba, Friday, 25 February 2022

The term on-site machining (OSM) refers to machining performed at the location where the breakdown or maintenance occurred. This process speaks to the operating philosophy of machining within dedicated work areas instead of components being transported to remote workshops for refurbishment. The on-site machining process possesses the merit of being fast, cost-effective, and reducing downtime. 

Despite the enormous advantages over traditional workshop floor machining for maintenance and repairs, little is known about OSM in Africa and most developing countries, although this field of machining has been around for decades. Early inventions can be seen on patents, such as the portable milling machine dating back to 1970 by the National Aeronautics and Space Administration (NASA). 

Convenience

The patent related to milling tube or pipe ends to a shape that the machine operator desires. The invention introduced the portable milling machine for tube ends that were out of round shape instead of the typical approach of using tracks secured to the outside diameter of the pipe. In such a case, the portable milling machine brings the convenience of machining non-standard-shaped components within the dedicated plant location. 

The requirements for machining on-site vary across industries, such as power generation, oil and gas, petrochemical plants, mining, earthmoving and construction, manufacturing, ship building and repair, forestry, pulp and paper, and water utilities. The requirements for machining on-site are largely due to components that rotate, requiring maintenance and repairs due to wear and tear. The scope is limited to the challenges of rotating parts and overall components that require surface restoration or, in some cases, bolts or studs that have seized on removal. Possible multiple applications have not yet been explored, and as such, advancements in the design of portable machine tools have seen improvements but with room for more work to be done in the advancement of the field. 

Upgrades

The initial machine designs in on-site machining, which are still largely in use, are based on the upgrade of conventional machines such as centre lathe, milling machine, drilling machine, surface grinder, horizontal boring mill etc, located within most machine shops. Thus a conventional centre lathe utilized within a machine shop would have a portable version but one that would be mounted on a shaft in situ for machining. Most portable machine tools in current use are based on this principle.  

The application of OSM has numerous advantages for clients, especially during outages or shutdowns. Where components need to be stripped down for maintenance and repair purposes, the transportation of components to remote workshops is often required for machining applications depending on the condition of the component. In other instances, components cannot be removed from the site, which presents a  challenge where machining is required. The transportation of components has its disadvantages as most of the components are often large and require abnormal transportation. In addition, the energy utilized to transport such large components adds carbon emissions to the environment, compounding the disadvantages of machining off site. 

In position

Portable machine tools are usually transported by vehicle, such as a single or double cab vehicle. The machines are normally electric, hydraulic, or pneumatically powered, and they would be connected within most power plants or areas where the components are located. The component is machined in position eliminating the need for a complete strip down, where applicable. A complete strip-down of the component lends itself to scope creep, as some parts require additional work. 

Downtime through OSM is reduced to a minimum as some machining can be carried out during a shift with minimum interruption to the plant operation. The result to the client is a saving in time and money as opposed to the costs associated with a complete strip-down for maintenance, repairs and work carried out off-site. In addition, the client witnessing the work being carried out in situ removes the possibility of unknowns resulting from work conducted off-site.

Working from Work

Posted By Prof. Danie Hattingh, Tuesday, 14 December 2021

A quasi-consensus has emerged among many of us that ‘working from home can work’, however is this better than working from work? Was the model we followed in the past (working from work) so wrong, or did we create a ‘new’ comfort zone for which we have not calculated the cost nor long-term impact?

Covid-19 forced us to make decisions swiftly to implement new untested ways of doing our work from home with little face-to-face interaction. The changes we implemented initially, were pragmatic and very much human centred, resulting in most adjustments being favourably accepted, with no real debate on the long-term impact. People adapted very quickly to a different style of life – more home/family focused while trying to work effectively from home.  

Personal or family considerations suddenly become integrated with our professional lives, elevating family considerations to a higher reality during “working hours” than we would normally experience during a working from workplace environment. 

Not being able to make eye contact or hiding behind a mask forced colleagues to adopt new ‘coping’ mechanisms. Communication and coordination had to become sharper with more frequent, e-meetings becoming the norm which quickly became more ‘evil’ towards productivity than emails. We quickly developed a habit of hopping from one e-meeting to the next by the click of a button or by switching to a different platform.  A typical workday scorecard could easily lean towards hours of e-meeting vs zero productivity or invoiceable work – still with some satisfaction that it was a busy and productive day’s work (energy sapping e-meetings).

The question that needs answering – was the model we followed for the pre Covid years, on which we built our economic success so wrong? Were we that naïve in the past that the then ‘status-quo’ became so comfortable that we did not see the need to change.  Many of us certainly made frequent reference to, ‘cannot continue to work the way we are working – something must change’, does it sound familiar, however despite this concern we never could come-up with a better model until Covid-19 appeared.  

The current challenge, considering the devastating effect on our economy, is not to allow the Covid-19 mindset to blunt our senses. We need to recognise the realities and demands for making a living in the world we live in. Can we really claim that our response to Covid-19 by the introduction of working from home and using e-platforms is the new way of creating a better future for all? 

My experience is that everyone is trying their best to plan, manage projects, schedules, and activities from home with very few thinking about the efforts required towards reconnecting the economic ‘wires’, enabling the economy to gain momentum – ultimately this is the only way for creating employment, generating revenues for paying salaries or taxes to fund private sector and government initiatives.  

Should we continue to make ‘clever’ plans to show the world how we can beat Covid -19 without calculating the real impact or long-term value of these plans (e-meetings, e-learning, e-nothing, e-working, e-working from home) on the economy. When we make decisions around closing schools, continue with non-contact education and non-essential businesses, we need to realise that these decisions have long term consequences  which we do not yet fully comprehend. 

Are we seriously considering the impact on humans of a prolonged economic shutdown, graduates who never experienced interaction within a class or laboratory environment – are we really comprehending what we are asking people to do, or are we just riding this wave to increase our own comfort zone at the cost of generations to come?  Do we have a new plan for the future, where we all work from home or is this just another clever phase in our self-destruction?

We need to use every possible opportunity to influence policymakers to reopen the economy, reintegrate work from work where needed and consider the impact of doing education online for future generations. Many people cannot work from home as they do not have a home, making this approach an ethical dilemma for which we need answers.   In my opinion, the current mindset of people is skewed toward egotistical needs for which we have not done the sums. 

Let us challenge this newfound comfort zone of working from home so that we can ensure we thoroughly understand the long-term impact of this approach before we make it the new NORM.

The Transition to Renewable Energy

Posted By Frank Kienhöfer, Thursday, 18 November 2021

The Transition to Renewable Energy

The global debate on the existence of global warming and the urgency to reduce CO2 emissions has shifted to the best method of transitioning to this new decarbonized world. The European Union has set a target of reducing CO2 emissions to 100% below 1990 levels by 2050. Cynics may question the feasibility of this ambitious target and the timidity of setting targets rather than laws, while optimists may argue, “Aim for the stars – you may reach the moon.” 

The UK, notwithstanding Brexit, has arguably taken the lead by passing the net zero target for 2050 into law; while on the other end of the spectrum Poland appears reticent to support CO2 emissions targets. Across the Atlantic, we see a similar mixed approach with California taking the lead in decarbonization and the oil states being less supportive. 

Tackling global warming requires worldwide and immediate joint effort in which regional vested interests will need to be negotiated. Europe and the United States have made massive progress in reducing CO2 emissions such that South Africa cannot continue with business-as-usual. Our current technology imported from Europe and America, will become unavailable. As an example, Volvo, DAF, Daimler, Ford, Iveco, MAN, and Scania have all pledged to end diesel truck sales by 2040. These truck brands deliver over 90% of the long-haul road freight in South Africa and are the backbone of our supply chain network. 

New energy source

Overseas investment in projects which emit CO2 emissions has ceased, and Europe, our biggest export market, appears likely to implement a carbon import tax on products associated with CO2 emissions. The following article will discuss our required transition to a low carbon economy. South Africa needs to focus on poverty alleviation and job creation within the context of positioning itself in this new low carbon world economy.

At the heart of this transition is replacing the burning of fossil fuels with a new energy source. Progress in the 20th century was made possible by burning coal, oil, and gas to power mechanized machines for farming, mining, construction and mobilize goods and people. In 2020, 5 out of the 10 largest companies in the world by revenue were oil and gas industries, which demonstrates that energy is a key economic driver to our global economy.

Through a combination of using a cleaner energy mix of wind turbines, solar power plants, and gas-fired rather than coal-fired power stations, and greater efficiencies in using this energy in industry, businesses, and homes, both the UK and Germany have led the way in reducing emissions by around 50% compared with their 1990 levels: with continued improvements still possible. Further positive developments have been the emergence of electric passenger vehicles as a viable alternative to internal combustion engine vehicles. Battery electric vehicles made up 54% of all new cars sold in Norway in 2020, and a modest 6% but growing in China. Challenges however remain. The cost of energy storage is currently limiting a full penetration of intermittent renewable energy sources to provide high quality uninterrupted power.

Hydrogen

Hydrogen fuel (or using hydrogen as an energy carrier) has been proposed as a solution to store surplus renewable energy by electrolyzing water to be used again when the sun stops shining, or the wind stops blowing. Hydrogen has an energy density 2.6 times that of diesel which is extremely positive, but the economic feasibility of a hydrogen powered industry including hydrogen production and distribution needs to be questioned and compared with state-of-the-art alternatives. 

The argument that the future glut of cheap renewable energy will power a green hydrogen economy does not hold water. Currently 98% of hydrogen is produced from natural gas using the steam-methane reforming (SMR) process. This cheaper hydrogen production process, as compared to electrolysis, commonly releases CO2 into the atmosphere. The production of electricity directly from methane is cheaper than the production of electricity from hydrogen produced with SMR. 

The production, distribution, and utilization of hydrogen requires water purification, compression or liquification, distribution and conversion back to electricity through a fuel cell. In each of these processes, energy is lost to the point that only 35% of the original energy is useful.  This is 3 times less compared with the energy stored in a battery. Using a realistic energy grid, which is not 100% decarbonized, each unit of electricity derived from a hydrogen fuel cell is responsible for 3 times the CO2 emissions derived from a Li-ion battery.

No meaningful penetration

The freight haulage business is extremely price sensitive, which is why hydrogen fuel cell technology has made no meaningful penetration into the commercial vehicle market for which it is hyped as the solution to the weight of a battery. The flagship hydrogen fuel cell vehicle is the Toyota Mirai, which is a passenger vehicle. Toyota has contributed immensely to the world economy in furthering lean engineering and waste reduction, but the waste of energy in driving a Toyota Mirai compared with a battery electric vehicle is at loggerheads with Toyota guru, Taiichi Ohno’s waste reduction principles. 

The VW group, comprising MAN and Scania, which accounts for 1/3 of commercial vehicles sales in South Africa, has ceased further investment in hydrogen technologies in spite it being currently the only heavy-duty vehicle manufacturer with hydrogen vehicles in operations with customers. Scania’s Head of Sales and Marketing, Alexander Vlaskamp, “To do what’s best for both our customers total operating economy and our planet, we are not closing the door on any possibilities. It is clear that Scania’s focus in the here-and-now perspective as well as short- term is a combination of renewable fuels and battery electric vehicles. We see that for basically all segments.”

Nuclear energy is also no silver bullet. A nuclear power plant takes 10 years to build, which is how long we have taken to build coal power stations Medupi and Kusile.  Realistically South Africa cannot afford the capital investment for a nuclear power plant. Furthermore, it is a challenge to vary the power output of nuclear power stations to track the energy demand variations and dips of energy output from solar and wind. South Africa should continue with plans to extend the life of the 2 GW Koeberg but not plan for new nuclear plants which we cannot afford.

Energy needs

South Africa’s current electricity mix of 4% from solar and wind provides ample room for expansion with the most potential for overseas and local investment to decarbonize our electricity supply. Other good news is that South Africa has expanded the Lesotho highlands hydropower stations from Phase I to Phase II (currently at ~72 MW with an added ~110 MW almost complete) and pump storage schemes (currently at ~1000 MW with ~1000 MW almost complete). South Africa’s hydropower is only a fraction of our energy needs but orders of magnitude greater than the world’s largest hydrogen electrolysis plant planned for Leuna, Germany to start production of green hydrogen in 2022 (24 MW). 

We also have extensive local expertise and knowledge in the successful implementation of the 2 GW, 1 400 km, transmission line from the Cahora Bassa hydroelectric plant. Eskom should focus on maintaining an efficient electrical energy distribution system, which is an important piece of the decarbonization puzzle. It is likely that the best solution to the renewable energy transition in South Africa will be a combination of low cost solar, wind and hydroelectric schemes with local battery storage and efficient electricity transmission and schemes to balance power demand and supply like using privately owned electric vehicles to power the grid during periods of peak demand. 

Before expensive decarbonization infrastructure is planned, the use of energy in the most efficient manner possible in industry, businesses, and homes needs to be pursued. These efficiency interventions alone will not get us to zero carbon emissions, but they importantly do reduce emissions, they pay for themselves, and they make the final infrastructure spend on low carbon energy production and storage less demanding. Plant managers should ensure controllers are at the correct set-points with continuous improvement plans in place to reduce energy costs. 

More than golf carts

Although South Africa’s office heating demands are modest in comparison to the Northern hemisphere, heating systems should use electricity and heat pumps. Innovative legislation to unlock high-capacity transport i.e., the Performance-Based Standards initiative which has demonstrated a reduction in CO2 emissions by 19%, should be supported by government. Government needs to further campaign and advocate for the slice of the electric vehicle manufacturing market. The automotive manufacturing sector in South Africa accounts for 6% of our current economy. We currently stand to lose an important export revenue stream if we continue to manufacture internal combustion vehicles. 

Removal of the 25% import tax on electric car imports (which were intended for golfcarts), would send the correct message to the likes of VW, Tesla and BYD to consider manufacturing electric vehicle plants in South Africa. Upgrades and electrification of our train system (sadly dogged in recent years by tender corruption scandals) is needed to make rail transport more attractive. Using predicted GDP growth and freight models, South Africa’s transport demand will require several additional lanes to the Durban-Gauteng and other major freight corridors in the next 20–25 years. Rail needs to play its appropriate role in the national freight transport system by reducing pressure on road infrastructure along long-distance, large volume corridors. This would further our national decarbonization efforts.

Way forward

South Africa will need to contribute to a decarbonized world economy and towards this end focus on using energy more efficiently. Energy efficiency is our only hope to dig ourselves out of the hole of being bankrupt but still make deep, meaningful cuts in CO2 emissions; the efficiency improvement interventions paying for themselves. In this respect, using hydrogen as an energy carrier and the hydrogen economy is a nonstarter. 

The Koeberg nuclear plant should be maintained but any new nuclear build is unaffordable. Eskom and the government need to focus on a fair and conducive regulatory framework to allow solar and wind plants to be financed and built and focus on maintaining an efficient distribution system to transmit electricity. We advise the SA government and industry to be guided by the most recent developments. The current and most affordable power systems are based on solar, wind, battery energy storage and hydro where possible.

From a crisis to a cure – Securing the future of Engineers

Posted By Gerhard de Clercq, Wednesday, 25 November 2020

South Africa’s unique challenges creates the perfect breeding ground for young engineers to develop into extraordinary problem-solvers. But a contradiction exists, evidenced by the sheer volume of unemployed graduate engineers. How can this possibly be true, when we are constantly reminded that Engineering is one of the top three scarcest skills in our country? 

According to ECSA, South Africa lags globally in terms of engineers per population. It is estimated that our country has one engineer for every 1 600 people whereas internationally one engineer serves 40 people. Due to current economic circumstances, operators of critical infrastructure have been placed under severe strain to such an extent that they are currently losing valuable expertise, skills, and experience through organisational restructuring measures. 

This is hardly good news for an industry where graduates are at home while we are supposed to fill the pipeline with future leaders and figures of technical authority. In addition, we are frustrated by the common belief that South African problems cannot be solved by South African engineers. 

We under-sell ourselves. Engineers already have the wireframe of formal and voluntary associations to enable the same level of professional organisation as in the medical and financial sectors, yet we allow ourselves to take a back seat. Our profession needs engineers, companies and associations to join hands to realise a shared vision. A vision where knowledge sharing, collaboration and recognition will result in the development of engineers from graduates to masters in their craft. 

It is an investment that may only return dividends over the long run, but will ultimately ensure the long term sustainability of both entities alike. 

For example, in my company which has as established Mechanical Engineering department, brilliant people are valued by their peers, trusted by clients, and respected by the competition. But even this situation has an ever-encroaching expiry date. One that can only be extended through youth, community, and investment in competence. 

In our company, we often say that the most experienced people do not have a monopoly on good ideas. SAIMechE provides a platform where engineers with varying experience levels contribute to support the voice of our profession and share good ideas, regardless of industry or company affiliation. 

SAIMechE promotes the involvement of students in technical and networking events, which in turn provides the opportunity for companies to spot and acquire talented people. In addition, SAIMechE’s company affiliate programme is instrumental in providing companies with the platform, audience, and support to give back to the mechanical engineering fraternity. 

Collaboration between companies and voluntary associations is imperative, as together they support each other through conferences, seminars, exhibitions and many other endeavours. 

It’s an exciting time to be an engineer in South Africa. We refuse to allow external crises to determine our fate. We are not simply obliged to invest in the youth, our very survival depends on it.

The Cidb Regulations and Project and Construction Management

Posted By Steve Hrabar, Thursday, 16 July 2020

Many of our members have approached SAIMechE as to the Construction Industry Development Board (CIDB) regulations regarding the Practice Note of registration with the South African Council Project and Construction Management Professions (SACPCMP) as Project Managers and/or Construction Managers for tenders and contracts that Industry and State Owned Enterprises (SOE’S) have issued. SAIMechE in turn made representation to the Council of the Built Environment (CBE) to clarify this guideline and to seek their opinion about this issue as both ECSA and SACPCMP reported to the CBE. As a result CBE hosted a meeting between CBE, CIDB and SAIMechE to examine and clarify the interpretation of the CIDB Practice Note.

CIDB was formed by Government and Industry to regulate the construction industry for Government
Tenders and Contracts (Including SOE’s) and to have a process of eligibility for the work, tendering,
contract award and quality of workmanship. It is established in terms of the CIDB Act 38, of 2000.

The role of the CIDB is to facilitate and promote the improved contribution of the construction industry
to South Africa’s economy and society.  At our meeting, CIDB presented Practice Note #31
dated the February 2014 where they clarified their interpretations of the need for registering of Project
Managers and Construction managers to fulfill their mandate. The relevant extracted section of Practice Note #31 is shown below:

1.Background
The July 2013 CIDB Regulation Amendments (gazette No. 36629 of 2 July 2013) removed the requirement for “qualified persons” (or registered professionals) as a contractor registration requirement (Regulation 12(4) and Tables 4A and 4B).  The intent of removing the registration requirement for qualified persons is to move to a requirement for clients to determine and specify the specific technical resource requirements on projects, based on the scope of work, complexity and size of the project. This Practice Note provides guidelines to clients to specify eligibility requirements for registered professionals to undertake the management of the construction works contract.

2.Construction Management
In terms of the relevant Acts, SACPCMP and ECSA register professional persons who are competent
to undertake such work – including construction management. The recognized professional persons  that are competent to undertake construction management are denoted as:

Within the ECSA system, the level of complexity, or “characteristics of engineering practice” that
can be undertaken by the Professional Engineer, Engineering Technologist, Certificated Engineer or
Engineering Technician is covered in ECSA Regulations.  The ECSA Code of Conduct also requires  that registered professionals can only undertake work for which they are competent to perform.
It is further noted that in terms of the draft regulations for the “Identification of Work” (IDoW), it is
possible that the single-point accountability for construction management may be restricted to
registered professional persons.

The results of the interaction between CBE, CIDB and SAIMechE resulted in the following findings:
1) Industrial clients are not bound by CIDB regulations, other than requirements for the registration of construction works contracts and requirements in terms of the CIDB Project Assessment Scheme and the CIDB Best Practice Fee. Other than this, the notion of Industrial clients that they must follow the CIDB regulations or Practice Notes is ill-founded, but the CIDB recommends that Industrial clients consider the CIDB Practice Notes. Industrial companies can follow their own procedures determining their own requirements of Project Management and Construction Management for their projects. There is no requirement to be registered with SACPCMP. However it is recommended that the design of the project should be under leadership of Registered Persons of ECSA. Notwithstanding this, the CIDB recommends that the construction of industrial works is managed by an ECSA or SACPCMP Registered Person.

2) Government clients and SOE’s must follow the CIDB regulations. In addition there is no obligation to be registered with ECSA or SACPCMP, although guidance for project and construction is given in CIDB Practice Note 31.  SAIMechE hopes that this matter is laid to rest. We thank the executives of CBE and CIDB for their pro-active input in clarifying these matters.

Connecting with the World of Engineering Education

Posted By Deborah Blaine, Friday, 08 May 2020

In July 2019, people from all over the world gathered in Cape Town to participate in the Research in
Engineering Education Symposium (REES 2019), an event co-hosted by the global Research in Engineering Education Network (REEN) and the South African Society for Engineering Education (SASEE).  

The participants were researchers investigating engineering education in local, national and global contexts; educators who teach engineering students everything from fundamental mathematics to the professional communications skills they’ll require to become professional engineers; technicians and technologists; academic support staff who work hard to help students and lecturers in crafting effective, efficient, innovative and equitable learning opportunities.  

We even had engineering students alongside lecturers participating in a workshop where researchers juxtaposed approaches to decolonisation relevant to engineering in San Diego, CA, USA with those in Cape Town, RSA. Over the few days we met, I was struck by the similarity in challenges facing engineering education across the globe.  

The fundamentals of engineering science have not changed significantly over the past 20 years, however, the number of students in our classes has grown dramatically.
Our students’ educational, socio-economic and cultural identities are far more diverse, and the challenges that they face are those related to the rapidly changing context of our global society, and
the uncertainty and unpredictability of the future of humanity, exacerbated by Covid-19.  

At the same time, there has been innovation to teaching and learning in engineering education over the past couple of decades. We use the internet, smart phones, teamwork projects, project-based learning – basically any innovative idea that we can access in order to reach the many students in our classes.  Furthermore, we no longer teach classes of 50 students, but up to 500.


Modern academic
The number of students in our classrooms who are first-generation university goers has increased dramatically; there are more than five girls in our graduating classes; we know that some students learn well through pictures, others through discussions and groupwork, others through reading. The days of a lecturer standing in front of a class for 50 minutes, three times a week, and speaking to the class non-stop, are gone.  Many universities across the world now require the modern academic to submit a teaching portfolio showcasing their reflection on and practice in teaching and learning, as well as their disciplinary research excellence in order to move up the academic ladder. Within this productivity driven environment, it is understandable that lecturers are gathering to share practices and ideas that relate to both engineering and learning.


In South Africa, SASEE (founded in 2011) has been instrumental in building this community of practice
and creating opportunities for engineering education stakeholders to work together to navigate the
complex world of building knowledge, transferring skills, and preparing young engineers for industry.


Collaboration
The REES 2019 conference provided an exceptional opportunity for our South African community to collaborate and share their experiences with colleagues from Europe, North America, Asia, Australia, South America and the rest of Africa. What was encouraging to observe was the quality of engineering education in South Africa, the dedication of the educators and researchers who are truly invested in growing engineers for our country, and to recognise that the issues we struggle with resonate with those experienced by our colleagues across the globe. 

What we missed at the conference was the voice of the industrial and commercial engineering community, a critical stakeholder in the engineering
education project. Each of our SAIMechE members studied engineering somewhere. We are living in
the same dynamic and challenging world for which engineering educators are trying to prepare our
student engineers. SASEE would like to invite and encourage our mechanical engineering community to get involved in shaping the engineers of our future.  

Despite all the complaints that we make about our educational systems and the difficulties we face with our economy, we have so many vibrant, intelligent and dedicated young people who want to become engineers, who want to grow our country and our engineering community. It is our duty to work together to create a fertile academic environment in which they can grow and succeed.

Value Proposition for Your Membership

Posted By Cillia Molomo-Mphephu, Tuesday, 10 March 2020

What is value for your membership?  Well, before we get to that, maybe it's worthwhile to ask who are we?  The South African Institution of Mechanical Engineering is the senior body representing the discipline of Mechanical Engineering in South Africa (SAIMechE).

We remain steadfast in the view that "By Knowledge We Advance".  That brings us to the significance of the engineering opinion, particularly, related to the Mechanical Engineering discipline.

To understand the importance of our opinion, perhaps a good place to start will be where that opinion is going to be applied and ultimately its impact on the economy.  Think infrastructure for aviation, rail, road, marine and their corresponding systems including their different modes of transport; infrastructure for utilities; medical equipment, mining infrastructure and other such significant assets.

Where Does one go for an opinion on the above?  It should be undisputed that the home of such opinion is, predominantly, SAIMechE.

Home of the Mechanical Engineering Opinion

Lest we forget that the screw pump at a wastewater treatment plant, massive as it is, is useless without an electric motor.

On the other hand, both these pieces of equipment are controlled by a Programmable Logic Controller (PLC) which is electronic.  Need I say more!  Well, of course we will still defend the Mechanical Engineering opinion with appreciation of the equally significant roles played by other disciplines.

But I said "home" of the Mechanical Engineering opinion.  I want to made an assumption that each time one refers to a place as home, a sense of belonging, of pride, of security and of freedom, among others, quickly takes over.  Now, open the door of that home, walk in and only find one member sitting there.  Surely you will have doubts in as far as one person's opinion versus the scope of what is expected from a regular home.

One the other hand, the consolidation of many authors'  views is that engineering is the application of science and mathematics to solve humanity's problems.  Given the wide variety of problems in this regard, it makes sense that the logical and structured approach might not be adequate to assist in finding such solutions.

The home owner

Of course the home owner's role cannot get easier that keeping family members happy and engaged to maximize and sustain their sense of belonging.  But simply saying "keeping members happy" does not provide much.  The organisation will have to, together with its community, unpack that to the satisfaction of all members.

Many sources I have consulted on organisational membership suggest that the organisation must ensure provision of continuous value for its members.  While that might be correct to some extent, I'll still go ahead and rephrase that to suggest that the organisation must ensure provision of platforms for creation of continuous value, because what organisation can ever have a conclusive position on that constitutes value proposition for its members without their involvement?

Notwithstanding the fact that members' involvement provides ore clarity on what they see as value for their membership, it is also expected that their involvement will give them a sense of owning that part of the organisation to which they have contributed.

I suppose it's a safe assumption, again, to suggest that members who are having a sense of belonging will stay and , further, automatically continue to engage meaningfully for knowledge creation and sharing.  And, what better place for the Mechanical Engineering stakeholders that in SAIMechE.

Fortunately, SAIMechE already has many platforms to enable easy value exchange for its members.  To count but a few, the website and its many features; and also a number of contact sessions.  Although those platforms are very important, they should not be confused with real value for membership, which I will attempt to get to, soon.

The role-players

Why do we want to congregate?  Is it because we want to achieve shared goals/outputs?  I'd say yes... The importance of achieving results together cannot be underestimated.  Out of that comes member confidence and a sense of fulfillment for those who played a role.  Arguably, people who achieve together are likely to stick around together.

The question, however, remains whether the SAIMechE membership numbers are adequate enough to provide for a representative opinion.  According to our records, females in articular make up a heartbreaking 8.9% of the total number of SAIMechE members.  Accounting to the Engineering Council of South Africa (ECSA), South Africa has one engineer per 2 600 people compared with international norms, where one engineer serves 40 people.

Considering that we've already seen here that the engineering scope can never be perfectly designed to allow for the engineer to follow a logical and structured approach given the wider scope of the problems to be solved, the more innovative and progressive opinions from the members the better!

The organisation provides for a wide variety of categories to enable a wide range of role-players:  Company Affiliates, Associates, Honorary Fellow, Fellow, Graduates, Students and open category members where all qualifying stakeholders of this profession are invited to come and contribute meaningfully.

And on a biased note, given the slow uptake by females in this profession, I particularly urge all eligible female persons to rise up and make a difference in this profession.  Their colourfulness is sorely missed!

The value proposition

Is it incentives, rewards, and the likes that will make you proud each time the name SAIMEchE is mentioned; or is it SAIMEchE's credible engineering opinion that cannot be ignored by society that will make you proud to belong?  I choose a credible engineering opinion.

Whichever one you choose, please still come and advance the organisation with us!  With more members' involvement, we can be certain of a more accurately defined value proposition, and therefore a better output for SAIMechE.

The Transition from Student to Mechanical Engineer

Posted By Cameron Hofer, Tuesday, 17 December 2019

While at university a mechanical engineering student typically only catches a glimpse of the engineering world through the lens of academia, with focused growth in the technical fields of thermodynamics, fluid mechanics, materials strength, calculus and the various forms of computer aided
design. This focused technical growth typically culminates in a final year design project, whereby these new-found skills are applied to the design process of concept formation, detailed design, prototyping or testing and finally manufacture.  Graduate engineers moving into the working environment will need to continue their steep learning ascension, this time mostly through the learning of the ‘soft skills’ required in order to be effective in the workplace. The discovery is soon made that a working engineer’s time is not their own and the priorities of clients and managers must be carefully balanced in order to produce an effective design that may pass the hurdle of financial viability.  To achieve this, a graduate engineer must adopt the mantra of ‘keep it simple’, which must be uttered at the beginning of each new project. Nothing fuels the vanity of a graduate engineer quite like the belief that what is existing and proven in the market need not be considered. The benefit of using standardized and proven equipment and techniques is a significant reduction in cost and the use of the knowledge of the engineers who have come before you.  

First principles

However, a working engineer must be able to identify the level of engineering required to solve a problem to within an acceptable degree of accuracy.  It may be a priority to quickly solve a solution by using proven design and empirical formula, but for more complex problems the use of first principles and Matlab type calculations must be reverted to. Although simplicity is often the most revered solution in industry, it is often the most difficult outcome to attain.  The newly graduated engineer must then extend themselves beyond the technical learning received in university and consider the more complicated variables of manufacturability, politics, material cost, trade-offs and HAZOPs.  The intuition of what equipment must be procured from overseas, or what must be produced locally cannot be taught in university. University also cannot teach the challenges involved with getting a construction crew’s equipment through the Zimbabwean border, nor can it teach the intricacies of identifying and managing potential risks in the execution of a project. Scenarios such as these can only be learned through experience.

The Real World

It must be further considered that the product being designed will unlikely be used in the ideal world on which university models are based. In the real world, pipelines may become fouled with time, upsetting an engineer’s delicate pipeline pressure loss calculations.  Instabilities in a process may be brought about by off specification material being fed into the factory. A good engineer must have the foresight to identify these potential “less than ideal” operating conditions and factor these into their calculations. To all the newly graduated engineers and those who are still studying, do not be discouraged. The world of mechanical engineering, especially within sub-Saharan Africa is an exciting adventure that presents many unique opportunities, that may not be known to those who are considering moving their careers abroad. My newly emerging career at a consulting engineering firm has seen helicopter rides to project sites in near uncharted regions of Africa, the comradery of a project team rallying against long odds to successfully meet a client’s requirements, and the dynamics of dealing with international projects.  I have been exposed to projects ranging from ethanol plants to transformer oil production facilities to food processing factories. The notion that opportunities do not exist in this country for young engineers is only true if you believe it. My advice to those entering the work place is to be open to every  opportunity that will be presented to you, any opportunity no matter how small or trivial will always have the potential to unlock further opportunities further down the line.

Engineering Activity and Professional Competency

Posted By Malcolm Black, Friday, 08 November 2019

The evidence of engineering activity is all around us. The homes we live in, the cars we drive, the telephones we talk on and the medical equipment we have to help us diagnose and treat our health issues. It is not possible to look around the built environment and not notice something that is the result of engineering activity. We live today very much in an engineered world. Further, this engineered world has very definite levels of complexity easily observed as we look around. From the “simple” piece of steel that is called a crowbar and used as a lever to get something moved to the hugely complex pieces of equipment that float around in space creating a network of communication devices that have become an integral part of our daily lives. Not so simple You may have noticed that the word simple was placed in inverted commas. Is the crowbar that “simple”? What material is it made of? How was that material made? How was the crowbar formed into the tool that is used in so many situations? How are similar crowbars (levers) used in various combinations of increasing complexity that form the various parts of machines used in our everyday lives. All this requires engineers who are competent to participate in complex engineering activities. Competence is a fundamental requirement of a complex evolving society. We have recently been informed that the South African population is approaching 60 million people. We are also told that close to 10 million are without work. Many do not have the basic requirements to live meaningful lives because of endless struggles with poverty. These Malcolm Black are complex problems requiring competent people to solve them. Professionals needed The SAIMechE has recognized the need for competent professionals to participate in the process of building a functional nation. Competence measured by objective assessment criteria that avoid any cultural, racial or gender “gate keeping” accusations. A Professional Development Programme that will enable graduates to develop the skills and levels of competence to make a valuable contribution to society has been developed. A competence developed through a guided interaction with experienced, accredited and competent mentors within commercial environments that are project oriented and deal with daily concerns and fundamental needs and issues. Candidate engineers, engineering business and society in general could benefit from this programme by giving support to it through participation, financial commitment and an awareness that without the involvement of competent engineers many of our complex societal problems may not be solved. The SAIMechE, through its numerous branches, is committed to serving the needs of its members and the community at large by providing this service.

The Nano-Mechanical Engineering Future

Posted By Rigardt Coetzee, Friday, 08 November 2019

Nanotechnology has become a future investment in the technology of tomorrow. This world offers advanced computers, smart homes to smart phones, the rise to artificial intelligence, and an innovative Industry 4.0. However, where and how does this new reality become possible? And how do conventional engineering degrees, such as mechanical engineering, manifest themselves into this exciting new field? In 1970 Moore’s law stated that the number of transistors in a dense integrated circuit will double every two years. This is only possible if the manufacturing process evolves along with time. This requires the use of engineers, researchers and scientists to evolve and innovate methods to make the popular Moore’s law possible. Simultaneously, these methods open up new possibilities and advancements in multiple new technological industries. But industrial growth requires the ability to manufacture. Nano-manufacturing offers a great deal of potential and needs engineers, researchers and scientists of multiple disciplines in collaboration to advance and produce creative nano-material, cutting edge technologies and efficient products. The manufacturing scale still remains a challenge and requires new innovative studies to investigate the fundamental physics/chemistry and then apply findings to optimize the production process. By doing so the limitations currently faced by nanotechnology manufacturing can be overcome. Nanotechnology: a multidisciplinary field To obtain an understanding of the underlining physics/chemistry of the nanotechnology field, a great deal of engineering across multiple disciplines is needed. In my own Engineering research, I found myself studying and collaborating with multiple departments. In the field of Atomic Layer Deposition (ALD), an ultra-thin nano film fabrication process, it demands the attention within mechanical engineering design; heat and mass transfer; computation numerical methods across multiple scales (being reactors, chemicals, to atomized scale); chemical reaction mechanism creation; material sciences; among others. These discipline fields are soon to be seen branching to consumer usage related studies, medical equipment implementation, artificial intelligence, micro- and nano-electronics, optics, and so forth. For future implementation, mechanical engineers of tomorrow should adapt and evolve themselves  into multiple disciplines. Furthermore, they should utilize their unique contribution in the field of mechanical engineering to optimize and innovate from the fabrication process towards equipment and product design. Engineers of the past revisited in a modern field Lately, I found myself invested and intrigued when examining the engineering papers and findings of the past.These texts, correlations, and descriptions of numerous phenomena, reveal similarities and parameters that may affect, or describe the unique effects currently found to be unknown in the Nano-Engineering domain. The past works are found to re-innovate the need to re-engineer the current nano-fabrication problems. They embark on the understanding of the fundamental theory, and intrinsically allow counter-arguments to be made to explain previously unknown behaviours. Progress through innovation For the continual successful progress of the implementation of nanotechnology, new technologies previously seen as impossible or a fable dream due to their limitations should now be pursued. Mechanical engineers should utilize their unique skills and abilities obtained throughout their years of experience to contribute to dreams becoming reality. The unique skills that the field of mechanical engineering offers, past or present, truly contribute to the engineering of the future. These skills will play a key role in the nanotechnology field thtough contributions towards nano-manufacturing. And thus the ever-decreasing size of products, the possibility of AI and even smarter technology will become a reality.

The Importance of Engineers in Supply Chain

Posted By Nicolass Swanepoel, Wednesday, 11 September 2019
Updated: Monday, 09 September 2019

Generally, one might think of an engineer as wearing a hard hat (a white one) and safety glasses, somewhere in a plant or construction site, carrying a set of drawings, trying to solve challenging problems or overseeing a project.  The many fields of mechanical engineering is so vast that the important or even critical roles engineers play in “less technical” environments are mostly misunderstood and overlooked. The role of engineers in supply chain and more specifically in strategic sourcing is a typical example. Supply chain offers engineers strategic roles with long term benefits to the employer opposed to the role of operations and / or maintenance engineers whose primary responsibility is to complete projects or start the plant up as soon as possible after routine maintenance.

As an engineering professional working in a design environment, awareness of engineering possibilities in supply chain was unknown.  Many companies still don’t realize the real consequences of strategic decisions taken (or not taken) in supply chain, including its effects on operations and vice versa.  The importance of having strong engineering individuals working in supply chain to make strategic technical decisions suddenly became clear as this would form the basis to ultimately reduce total cost of ownership (TCO) and improve plant availability without operations realizing potential changes to past “modus-operandi”.  Time spent in a supply chain environment highlighted important responsibilities of engineers which includes: obtaining a holistic view of e.g. mechanical goods and services within the local (and if applicable international) markets to ensure best standards and practices for procurement, establishing a common strategic direction for dealing with key suppliers and stakeholders, optimizing and standardizing procurement opportunities, management and optimization of internal approved vendors/manufacturers to ensure procurement that meets the relevant health & safety standards as well as local and/or international engineering standards and specifications.  To manage this effectively, a diligent engineering thought process is required to understand the technical requirements of internal business processes.  Further support in the form of broad knowledge and background of various, different engineering standards and specifications supports regular audits on suppliers to verify compliance.  One often hears of procurement challenges such as the recent train locomotives that was procured to the wrong specifications.  One can’t then help to wonder if there were any engineering involvement in the supply chain and possible technical standardization process. 

From a maintenance point of view standardizing on specific brands of equipment (e.g. pumps, valves, filters etc.) is in most cases a good approach.  This in turn brings benefits such as minimum / critical spares coordination, stock holding benefits and strategies that supports plant availability.  On the other hand, standardization can reduce competitiveness in the market and needs to be managed carefully, as this could make the plant vulnerable by being too reliant on one or two suppliers.  A critical challenge engineers in strategic sourcing face is to find that balance between ensuring security of supply, understanding stakeholder requirements and expectations, effectively managing total cost of ownership and technical and legal compliance through correct supply chain practices and procedures.

Although the role of a engineers in supply chain might be considered as “less technical” in the mechanical engineering environment it certainly is a critical and much needed role with responsibilities and deliverables that can achieve huge cost savings benefits for any company through transparent and diligent sourcing strategies.

Money Engineering: 101

Posted By Brita Govan, Tuesday, 30 July 2019
As engineers we spend most of our formative years expanding our technical and managerial experience, but rarely do we invest in cultivating the business acumen required to operate and run a profitable venture.

In lieu of this enterprise culture, we resort to the primal essence of a business, which for most of us means adopting a daily mantra of "job out - money in” the hustle of a small engineering company. As many an entrepreneur would know, managing a small business is more than just balancing the books and accounting for expenses, it’s about charting a course, sailing a ship and keeping it afloat. It’s about cash flow.

But do engineers make for good business owners? While it is inherent in engineers to itemise, systemise and optimise, we would sooner bury our heads in advanced triple integration, than formulate a 3 month cash flow prediction. For the most part, we lack the insight for trade and commerce, and cannot comfortably adopt these concepts without intentionally endeavoring into the finance-discipline.

Without these basic business essentials, engineers are short a tool to effectively and profitably trade our intellectual property as a small business owner. This, in turn, limits both the expansion of independent specialised engineering consultants within the engineering industry, as well as the individual life-span of these companies.

Ultimately, we require the empowerment of engineers, not so much with the principles of accounting, but rather with an economic–conducive ‘school of thought’. This would create appropriate flexibility in our thinking and assist us to incorporate relevant factors and dynamic variables into the functioning of a business. Paired with our natural ability for problem solving, good business savvy would prove highly effective in establishing smart and operational business strategies.

Substantial efforts have thus been made to ensure educated engineers are capable of designing and building fully functional ships, perhaps then the next step is to equip us to navigate the seas and sail.

Understanding The New Engineering Qualifications

Posted By Prof. Brandon Collier-Reed, Tuesday, 02 July 2019

In 2013, the Higher Education Qualification Framework was published that completely changed the higher education qualifications landscape in South Africa. The well-known NATED-151 curriculated NDip and the BTech will be completely phased out by all institutions by 2020 and are no longer part of the possible mix of qualifications.

The “old-style” qualifications being offered by Universities of Technology have been (or are in the process of being) replaced by an “integrated national framework for learning achievement” that includes, in the case of engineering, the introduction of the Bachelor of Engineering Technology (BEng Tech); Diploma in Engineering (Dip Eng), the Diploma in Engineering Technology (Dip Eng Tech) and the Advanced Diploma among a number of others. Meeting international standards he Engineering Council of South Africa (ECSA) has developed qualification standards for these new qualifications that are outcome-based (like the existing BEng programmes) and that meet the requirements of the International Engineering Alliance – a necessary requirement to be a signatory to the Sydney and Dublin accords. These accords (focused on Technologists and Technicians respectively) are international agreements between bodies responsible for accrediting engineering academic programmes and confirm that graduates of these programmes have met the necessary educational requirements to be registered as professional engineering practitioners.

Lack of understanding
My engagement with a cross-section of engineering professionals in recent ECSA workshops suggests that there is a lack of understanding about what this change is actually going to mean in practice. It is important to recognize that the “old” BTech and the “new” BEng Tech are two completely different types of qualifications – with different types of graduates. It is not possible to envision the level of competence of a BEng Tech graduate by drawing on one’s experience of BTech graduates. The BEng Tech is a structured, outcomes-based qualification with International Engineering Alliance-aligned graduate attributes and completed over three years; the BTech is a content-focused qualification.

In practice, the BTech often followed a NDip, together being completed in four years. The BTech and BEng Tech are therefore not equivalent qualifications simply repackaged and rebranded. For one thing, the entry requirements for the BEng Tech at National Qualification Framework (NQF) Level 5 are typically higher than those for the old NDip, also at NQF Level 5.

In brief, the graduates of the two sets of programmes are very different. A fundamental difference between the old NDip and the new Diploma qualifications relates to the duration of the workplace-based learning (i.e. in-service training). In years gone by, graduates of Universities of Technology could be assumed to have been exposed to a minimum level of practical workplace-based experience. This requirement is now significantly reduced in the new Diploma in Engineering and largely absent in the new Diploma in Engineering Technology qualifications and the graduates of these qualifications typically graduate with far less practical workplace-based experience.

The Universities of Technology indicate that the intention is to have different work-integrated learning modalities scaffolded into the curriculum of these new Diploma qualifications, but time will tell how well this is enacted.

The consequence of this transformation in the qualification landscape is that companies that employ graduates with a BEng Tech must be aware that they can no longer assume that these graduates will have the same level of workplace-based experience that could be assumed of the BTech graduate and will need to be inducted into engineering practice through carefully managed training programmes – much like the current Engineer in Training model that is used for BEng graduates. With the first of the “new” graduates already in the market, employers will need to reconsider just what they require from a potential applicant to demonstrate that they have met the requirements for the job.

Load Shedding and School Holidays

Posted By Gideon van den Berg, Wednesday, 15 May 2019

It’s school holidays and my children are at home. And they are bored. I suppose every generation stares in awe at their children who cannot see or comprehend the privileges they enjoy. I may as well “own” their boredom since I have through much grace and hard work, been able to put them exactly in this position. I’d like to come back to that analogy in a minute.

With the recent bout of load shedding – despite any previous events, I was again caught off guard. No torches (with batteries) nor a generator. At least we have a gas stove, but we struggled to find the  igniter. You may have a similar story.

There is a connection between my children who are bored despite having broadband internet, Lego etc, and my unprepared state for load shedding. That is of course: privilege. Not the politically loaded “privilege,” but the fact that engineers are working and succeeding (to a degree) to keep the power on. The privilege is being oblivious to the facts – being able to go about your business without having to worry about that as well.

End of innocence
While it is unclear where South Africa’s infrastructure is heading, this may be our childhood end. We are all aware of the fact that things are not as steady as we once believed. There is a lighter counterpoint in that engineers may just have gotten their “We told you so!” moment. Engineering, maintenance and the related procurement systems are now in the spotlight. We can be of critical value if we are able to put forward informed alternatives and opinions.

The catch is that apart from your neighbours and relatives who will take your advice on quotes for solar panels, geysers, generators with automatic changeover switches etc, your activism will not take you very far. You will need a platform and leverage for your campaign.

Actually, you already have those things at your disposal – your local SAIMechE Committee! Through your committee, it is really just two steps to pretty much anyone within ECSA or any other VA or collection of VAs.

Politics and the public can be influenced, if we manage ourselves as a trusted source of guidance and information. That is exactly what we were trained to do, but I don’t think we are stepping up to the plate like we should.

The take-away is this: make sure that you are informed – and then be very opinionated! And go make some waves at your local branch.

Being an engineer is not all taught, some things need to be learnt

Posted By Dr Martin Venter, Thursday, 18 April 2019

As South African engineers we are proud of our community, we have a reputation for hard work and innovation in many parts of the world, but we seem to be forgetting that our reputation is not based on what we were taught in the classroom, rather what we learnt from our betters once we leave.

In recent years there has been a strong focus on increasing the number of graduates coming out of tertiary education (at my institution there has been a 5-fold increase in output in a decade). Most of us are aware that to meet this demand academia has wrestled with many challenges resulting in updated curricula. Assessments have been streamlined and the digital era has been embraced. Contemporary graduates have a range of classical skills that will be familiar to the old guard but have also accrued a range of new skills. Some institutions have even begun emphasizing the ever illusive 'soft skills'; that the public at large wants us to have. The question here is; now what?

However good your formal education is, it is incomplete. Young engineers move out of the classroom and join other practicing engineers. Only here do they learn the values of our industry: honesty, integrity, responsibility, inclusivity, continuous development and professionalism. These attributes are passed down from generation to generation. The older generation either mentored the new graduates directly through EIT programs or indirectly through their interaction with new graduates. In this way we have built a culture of engineering.

In a recent news article Consulting Engineers South Africa laments the immigration of senior engineers in the age bracket 35 to 55 and notes the ‘huge number’ of new graduates. As a community we are fast becoming bottom heavy and will reach the point where there are simply too few senior engineers to provide adequate mentorship, and our values may no longer be imparted on the younger segment of our community. With their sheer number, the newly graduated engineers will dominate how South African engineers are seen globally and their behaviour will reflect all our values.

We can no longer rely on the passive interactions of the past (or our absentee regulator) to instil the culture of South African engineering on the new generation. If we want to maintain our standards of practice and reputation, we now need to plan how new additions to our community are socialized. 

Steps in this direction have been made in other communities. In Canada for instance many new graduates choose to participate in the ‘Ritual of the Calling of an Engineer’, which in the words of Rudyard Kipling; ‘...has been instituted with the simple end of directing the young engineer towards a consciousness of his profession and its significance, and indicating to the older engineer his responsibilities in receiving, welcoming and supporting the young engineers in their beginnings.’

Members of the voluntary associations are in the best position to engage with the youth to ensure that they gain the attributes that will keep our community strong. All it takes is a little time.

Amazing New Shoots

Posted By Vaughan Rimbault, Monday, 11 March 2019

This past year has shown me, in many ways, just how amazing people can be, but I have been particularly amazed by the enthusiasm, discipline and resulting activity happening at the youthful end of the SAIMechE membership pipeline.

At the November 2018 Council meeting we heard about the activities of the various SAIMechE Student Chapters, and the Council was very impressed.  In the three-month reporting period, the Student Chapters  arranged and hosted sixteen events involving seven tertiary education institutions and eight companies.  The activities included speed-mentoring, site visits, technical talks, conferences and recruitment drives.  There was some social interaction as well, and one chapter arranged and hosted a sold-out dinner dance at an up-market venue, which included sponsorship from a major bank which they secured themselves.

Shortly after the Council meeting I attended an industry advisory committee meeting at a tertiary institution, and rather than having to find my own way around the typically complex campus, I was pleasantly surprised to be greeted just inside the main gate by a group of SAIMechE Student Chapter committee members.  I could hardly miss them in their matching branded golf shirts, each holding a clear sign for those attending the meeting.  They guided me to a special parking space and then to the venue.  I felt like the most important person on the campus!  What a fantastic advertisement for SAIMechE from those who have only recently become members.  They were so proud to be identified with SAIMechE and to play a role in hosting guests on their campus.  They are also so keen to play a productive role in the profession, and are looking to their SAIMechE membership to help them achieve their goals.

My overall impression of the Student Chapters is that, in the main, they have been getting on with the job by themselves.  They have helped each other to form and manage the chapters.  They have drafted their own guidelines and procedures to be more effective in arranging their activities.  They have been careful with their expenditure and have managed their budgets effectively.  The Student Chapter AGMs and meetings that I have been to have been professionally run and focused on the interests of the member.  Meeting protocol is generally well understood and meeting minutes are concise and well prepared.  I don’t think that anyone is teaching the Student Chapters about the finer points of professional conduct - they are figuring it out by themselves, and learning important life lessons in the process.

In all cases of student activity there have been individuals who have responded to the call for service to others.  A handful of students arrange all the activities and put in the hours necessary to get the job done.  This is not unusual and we see this in all sorts of organisations relying on the voluntary service of members.   The individuals that serve will naturally stand out from the crowd because of their commitment, dedication and effort.  They may not realise it, but they are being recognised, and effort they put in now will produce some greater benefit in the future.  

I am very grateful to our Students Chapters for reminding me of one of the cornerstones of voluntary professional associations like SAIMechE.  That professional and personal growth comes through service to others, and that offers many opportunities and platforms from which to serve.  Serving means meeting other people, interacting with them and doing things collectively to serve the greater good. Serving means not feeling alone, but feeling part of a group.  Thank you for reminding me of all the good reasons for being a member of SAIMechE.

Understanding Mediation, Adjudication, Arbitration and Litigation

Posted By Graeme Lloyd, Tuesday, 29 January 2019

Many of you have watched the TV broadcasts of the Zondo Commission into state capture. The terms of reference of this inquisitorial inquiry are to determine the facts regarding accountability for what had occurred and probable reasons why. The rules of procedure adopted by this Commission relate more closely to Conciliation, Mediation, and certain Adjudication dispute resolution processes.

Arbitration and Litigation procedures follow a different legal process ending with an imposed enforceable finding to settle the matter. Civil litigation is a function of our Courts in resolving disputes and enforcement of a binding solution regarding the substantive rights and duties of the parties. Court decisions and procedures are subject to considerable legal constraints, rights and precedents.

The private nature of an arbitration agreement is essentially contractual, therefore failure on the part of one party to comply with this particular contract provision carries the same penalty as any other major breach of contract. The circumstances for appealing an arbitration agreement are highly restricted. The successful party can easily obtain a court order for enforcement.

Significant advantage
The settlement of engineering and construction disputes by means of arbitration confers a significant advantage over litigation proceedings, as the choice of arbitrator can be based on technical knowledge of the type of work associated with the dispute.

Obviously this of particular importance and interest to all engineers involved in projects and design contracts. If the court appointed presiding officer cannot comprehend the engineering complexity then a just and equitable decision is unlikely.

An additional advantage of arbitration over litigation is that the process is private and away from adverse publicity. The participants also have the mutual convenience of arranging the dates, venue and times for submissions and hearings that suit themselves.

The other remedies for resolving disputes are non-statutory, which means their form and procedure is not prescribed by law, and the outcome is also not legally enforceable, unless agreed in the rules of conduct. Because these processes rely on both parties negotiating in good faith, there is always the possibility that they could be a preliminary dress rehearsal for arbitration proceedings.

Willingness
Mediation can only succeed if both participants are genuinely willing to agree upon the terms of settlement. Their joint objective must be to strive to reach a win-win rather than lose-lose scenario.  The chosen mediator is not expected or mandated to recommend or propose a settlement solution. The mediator’s core responsibility is to act as an intermediary, seeking to narrow the field of controversy by facilitating dialogue and understanding between the parties. In our country, in the context of CCMA decisions, a conciliator is expected to propose a solution to the dispute.

Because these processes rely on both parties negotiating in good faith, there is always the possibility that they could be a preliminary dress rehearsal for arbitration proceedings.

Successful adjudication depends upon selecting an adjudicator who is fluent in the language of the contract. It is also essential that the participants agree on the adjudication rules of procedure and binding outcome. Legal representation is normally excluded. The format and content of the documentation submitted to the adjudicator is a vital ingredient for discussion at the preliminary meeting of the parties. An adjudicator plays a more active and interventionist role in the proceedings compared with an arbitrator.

The Benefits of SAIMechE membership

Posted By Vaughan Rimbault, Wednesday, 28 November 2018

The most common question that I am asked about SAIMechE goes something like “What is the benefit of being a member of SAIMechE?”.  Instead of a clinical corporate response, I decided to reflect on my own membership of SAIMechE, and consider how I have benefited directly from it.  To be fair, I have excluded anything to do with my role as CEO, and have only considered my experiences as a member.

Looking back on my professional career, I can now clearly see that it took a turn for the better from about the time I was first drafted onto the KZN Branch committee in the early 1990’s.  At that time, I wasn’t thinking of my professional development, but probably didn’t have a good enough reason to dodge the invitation.  I admit to often giving of my time grudgingly in those early years, and considered my service on the committee as part of an obligation to give something back to the profession, with no expectation of a benefit in return.  Now I recognise the significance of that point in my career, and am able to identify the many benefits that followed.

From the first committee meeting my mechanical engineering world started to expand.  I immediately met a handful of professionals and started hearing more about the world of mechanical engineering.  Up to that point, my only engineering contact was at work, which presented me with a very narrow and uninviting view of the profession.  I had very few professional colleagues at work, and spent most of my time engaging with the engineering trades on the one side, and management on the other.  By attending committee meetings and assisting with the organisation of activities, I started hearing of new industries, technologies and machines.  I heard the names of people in industry and started to connect the dots in the profession.  For the first time in my career I interacted with people who were focused on mechanical engineering, and it felt like home.

In the early years I didn't fully realise the value of a network of professional colleagues that I was creating.  Looking back, I would consider my professional network to be the most significant contributor to my development.  This network has consistently presented me with knowledge, experience, advice and support, and I could not imagine a more appropriate space in which to encounter these.

I have been the KZN Branch Treasurer for more years than I can remember, and this office has helped me to become a very competent bookkeeper and Pastel operator.  Branch accounts are quite small and manageable, and give great opportunity for learning. I now properly understand accounting and financial statements and can hold my own against any commerce professional.  Solid financial skills are quite lacking in the engineering profession, very much to our disadvantage, and it’s a pity more of us don’t realise how simple it actually is. 

In the role of Branch Chairperson I was able to practice and develop skills in chairing meetings, and developed an effective method of taking minutes which I still use to this day.  I was given many opportunities for public speaking such as hosting technical presentations, dinners and even the national awards banquet at the Durban ICC, and this has been very much to my benefit.

I could list a few more direct benefits that I’ve received, but the point I would like to make at this stage is that all the benefits came as a result of service.  I never set out to get any benefit from my service to SAIMechE, but reckon that I’ve received at least ten times that which I put in - perhaps even more.  I didn’t plan it that way, but just as exercise brings about health benefits, so service to the profession brings about professional benefit.

I look forward to many more years of enjoyable and productive service to the Institution, and to the multiple benefits that will follow.  The difference these days is that I think a lot more about it beforehand. That’s just the way it works.
