Protecting pedestrians a priority for SANRAL

New pavements have been constructed along the N2 in George, allowing pedestrians safe passage.

A key element of the construction was the use of local labour.

Residents of Thembalethu, Pacaltsdorp, Lawaaikamp and Ballotsview in George, Western Cape, can now walk safely alongside the busy N2 road.

The South African National Roads Agency (SOC) Limited (SANRAL) recently unveiled brand new, safer walkways that stretch about eight kilometres along the N2 between the York Street Interchange and the Garden Route Mall.

A new pedestrian bridge has also been constructed, allowing pedestrians and cyclists to cross the railway line at Meul River in safety.

Pedestrians are the most vulnerable group of all road users, “and safety is a big priority for SANRAL,” said the manager for the Western Region, Kobus van der Walt. “Approximately 40% of all deaths on South African roads are pedestrians.”

To ensure pedestrians do not cross the busy freeway, a 2m-high welded-mesh fence has been erected along the N2, separating the pathways from the road. The fence also stops stray animals from wandering onto the freeway, which has been a cause for concern.

A key element of the construction was the use of local labour. “This project had the added advantage of providing employment to many people from the George area,” said Van der Walt.

Manual labour was used to build the pathways. The rolling terrain made the project more labour intensive, as heavy construction vehicles could not operate on the steep slopes.

The targeted spend on small, medium and micro enterprises for the project was R24.3-million. In addition, R12.2-million was allocated for labour costs.

Upgrading the Pacaltsdorp Diamond Interchange

The Pacaltsdorp Diamond Interchange project included the widening of both the existing Pacaltsdorp Interchange bridge and the two-lane York and Beach Roads, which were converted to a dual carriageway, a four-lane road with turning lanes at both ramp terminals.

Sidewalks were also constructed, along with a traffic median island.

Existing asphalt surfacing was rehabilitated, traffic signals relocated, road signage and markings replaced and street lights added.

The Pacaltsdorp Diamond Interchange upgrade was a joint project between SANRAL, the Western Cape provincial government and the George Municipality. SANRAL contributed 50% towards the project, with the provincial government and the municipality contributing 40% and 10% respectively.

SMMEs benefit from R58-million project

Six rural communities in Alfred Nzo District Municipality, Eastern Cape, have benefitted from a series of training programmes and employment opportunities in the construction sector.

During the construction phase, the participants were provided with further on-site training and mentoring. The quality of their work was then assessed and moderated.

Twenty small, medium and micro-enterprises (SMMEs) and more than 200 local community members have benefited from a R58-million community development project in the Alfred Nzo District Municipality in the Eastern Cape.

Situated in the poverty-stricken Umzimvubu and Ntabankulu local municipalities, the project has brought employment, training and skills development to six rural communities that have experienced first-hand the devastating effects of unemployment.

Via a series of theoretical and practical training programmes, local SMMEs and their employees gained experience while employed on construction sites overseen by the South African National Roads Agency (SOC) Limited (SANRAL). They also advanced their Construction Industry Development Board (CIBD) grading levels, expanding their opportunities in the construction industry.

Training in construction

Over R55-million has been spent on training and management services for the construction of community access roads and pedestrian facilities along the N2, between Mount Frere and the Ngcweleni River.

In keeping with its policy of localisation, SANRAL undertook a community development project focused on recruiting and training 20 100% black-owned SMMEs. The project provided local communities with the opportunity to develop skills and gain the work experience needed to improve their CIBD grading levels.

After the theoretical training, the SMMEs were contracted to complete various assignments related to the construction of the access road and pedestrian facilities.

Employing a minimum of 10 local people each, the SMMEs were given the opportunity to work on approximately 400m of community access roads.

During the construction phase, the participants were provided with further on-site training and mentoring. The quality of their work was assessed and moderated.

All the SMMEs completed their allocated work within the contract period and SANRAL-appointed consultants are assisting the qualifying SMMEs to improve their CIDB gradings.

Increase in value

“Simply by working on this project, the participating SMMEs have increased the value of the projects they are eligible to tender for in the future,” said SANRAL project manager Thabiso Ngozwana. “This has far-reaching implications for their success and the livelihoods of their employees.”

Although the construction of the community access roads and related pedestrian facilities has been completed, some aspects of the training are still under way. The project is expected to be wrapped up in September 2018. “This community development initiative was and continues to be a success,” said Ngozwana.

“There were no delays on the project and the communities are using the access roads and pedestrian facilities. Not only that, the SMMEs working on this project were upskilled, improved their CIDB gradings and increased their chances of future work.

“SANRAL is committed to empowering SMMEs. They can be proud of their achievements on this project and we look forward to seeing them grow and flourish in the construction industry,” Ngozwana said.

SANRAL supports next-gen engineers

The national road agency has prioritised education, training and innovation, says SANRAL’s development planner, Elna Fourie.

SANRAL’s Development Planner, Elna Fourie, believes the roads agency is creating a pipeline of talent that will eventually benefit the entire country.

Education is critical to the development of South Africa, and the South African National Roads Agency (SOC) Limited (SANRAL) is focused on supporting the next generation of engineers, artisans and technicians. Development planner, Elna Fourie, looks at SANRAL’s contributions.

What is SANRAL’s approach to education?

“We strongly support the recommendations in the National Development Plan (NDP) to prioritise education, training and innovation. Without investments in these fields, the country will not be able to close the skills gap, create jobs or accelerate economic growth.”

How does investing in science, technology, engineering and mathematics (STEM) education contribute to SANRAL’s objectives?

“It is in our interest to support the emergence of the next generation of engineers, scientists, artisans and technicians who will plan and manage South Africa’s future road infrastructure.

“We are creating a pipeline of talent that will eventually benefit the entire country.”

What are your focus areas?

“We focus strongly on the training of teachers, especially from rural and underprivileged communities. A good example of this is our partnership with the University of the Free State. Here we are involved in the Family Maths and Family Science initiatives, which offer enrichment classes for student teachers.

“SANRAL also supports the university’s ICT laboratory for science, which gives learners hands-on experience at the Bloemfontein and QwaQwa campuses. It also offers opportunities for student teachers to extend their practical skills.”

What makes your approach unique?

“We involve parents and empower them with sufficient knowledge to support their children. This leads to a strong relationship among teachers, learners and parents that supports and contributes to better learning.”

How does SANRAL support learners and students who want to study further in STEM subjects?

“We offer scholarships to high school learners and we support them through mentorship and help with exam preparations.

“In the 2016/17 financial year, SANRAL awarded 133 bursaries to students in the fields of civil engineering, construction and the built environment. A number of these students are also offered internships at the agency and with contractors who work on SANRAL construction projects.”

Long walk to school is no more

Learners from schools in KwaMbonambi, KwaZulu-Natal, no longer have to walk great distances to school after receiving their own bicycles.

The Shova Kalula bicycle project aims to make things easy for pupils to access education.

Learners from KwaMbonambi in KwaZulu-Natal do not have to dread long walks to school after receiving bicycles from the Department of Transport.

Some 750 learners from 15 schools were given bicycles – part of the department’s Shova Kalula project – during a ceremony held at the Dondotha sports field on 23 January 2018.

The Shova Kalula bicycle project aims to make things easy for pupils to access education.

Speaking at the ceremony, deputy minister of transport, Sindisiwe Chikunga, said: “For now, we’re prioritising rural and poor schools where pupils walk more than 3km to 5km to school.”

Grade 12 learner Sphelele Khuzwayo, who attends Sibonokuhle High School, said: “This will help me to attend late classes because I won’t have to worry about the long distance to get back home.”

Phindile Mngomezulu from Dlemudlemu High School was grateful for being provided with safety equipment along with the bicycle.

Shova Kalula

The Shova Kalula national bicycle programme was introduced in 2001 with the aim of improving mobility and access, as well as providing social and economic opportunities for people, especially in rural, remote and poorly-resourced areas.

In support of the programme, a number of bicycle maintenance shops were established in the different provinces to deal with issues of maintenance and job creation and small, medium and micro-enterprise development.

Helping open doors to science and engineering

Isabel van Gend, the director of the Nelson Mandela University’s STEM programme, shares her experiences.

Isabel van Gend, the director of the Nelson Mandela University’s STEM programme, has high praise for the youngsters who attend the programme. “It humbles me to learn from some pupils that, regardless of circumstances, they excel.”

 Working with school learners attending the STEM educational programme at the Nelson Mandela University’s (NMU) Missionvale campus over the past seven-and-a-half years has been a humbling, uplifting experience for the programme director, Isabel van Gend.

The STEM in Action programme provides an opportunity for selected schools that have a track record of excellence to bring physical science learners and their teachers to conduct a range of Curriculum Assessment Policy-aligned experiments.

She described being involved in the programme as “an honour, pleasure and privilege to engage with learners from a range of socio-economic backgrounds”.

The programme plays an important role in promoting STEM subjects, science, technology, engineering and mathematics, and providing extra tuition to high school learners from Grades 10 to 12.

Van Gend has high praise for the youngsters who attend the programme. “It humbles me to learn from some pupils that, regardless of circumstances, they excel.”

“I gained insight into how difficult it is for a marginalised child to be a successful scholar when there is minimal parental support and hardly any role models. Their resilience and commitment are noteworthy.”

She says that seeing such learners achieve, regardless of their circumstances, is both “rewarding and satisfying”; even though over-crowding and the quality and quantity of the teaching offered from Grade R to Grade 12 often let down learners, irrespective of the success of some individuals.

For Van Gend, love is a central factor in the education process. “My journey has taught me that no child can resist love. For me as a white ‘makhulu’ (grandmother) I also experience the love from children we engage with.

“I feel very strongly that the racial divides in our country can be softened and remedied. Interacting with children from all races affords me the opportunity to show unconditional love and to assist with practical or theoretical problems.”

The STEM programme has given Van Gend the opportunity to give, but at the same time “I am very blessed that I have received so much affection, acceptance and trust from learners of the entire spectrum we interact with”.

The STEM programme has been running since March 2010. It is based on the Missiondale campus to allow for easy access to all the local communities.

Currently more than 2 500 learners from 36 high schools attend programmes on campus.

SANRAL and STEM

Fifty matriculants from Nelson Mandela Bay graduated from an educational programme hosted by SANRAL and STEM at NMU, in September 2017.

The South African National Roads Agency (SOC) Limited (SANRAL) and the Science, Technology, Engineering and Related Management/Mathematics (STEM) Fields Pipeline Project (PP) hosted a graduation ceremony for the learners at the NMU Missionvale Campus in Port Elizabeth.

The learners from various high schools in Nelson Mandela Bay participated in the Getting Ahead in Technology and Engineering (GATE) and Selected Learner Programme (SLP) presented by STEM PP also called the STEM in ACTION by learners and educators.

Van Gend, said: “It is rewarding to experience how these learners grab the opportunity of extra tuition and excel in Physical Science. If these learners progress into careers in Science and Engineering, I cannot ask for more.”

Road fatalities down over holiday period

The preliminary report on fatalities on South Africa’s roads during the 2017/18 festive season shows an 11% drop in the number of deaths compared to the same period a year ago.

Minister of Transport, Joe Maswanganyi, said that a significant decline was noted among young pedestrians aged 25 to 34, but there was a disturbing increase among those aged 35 to 44.

The preliminary 2017/18 Festive Season report indicates an 11% decline in fatalities on the roads when compared to the same period in the previous year – above the 10% target set by the Department of Transport.

“Our preliminary festive season fatalities for the period starting 1 December 2017 to 9 January 2018 show that there were 1 527 people who died on the roads in that period, compared to 1 714 fatalities in the same period the previous year,” said Transport Minister Joe Maswanganyi.

Figures for the entire holiday period from 1 December 2017 to 15 January 2018 show a total of 1 676 fatalities compared to 1 875 fatalities for the previous year.

“The highest number of fatalities was among pedestrians, which increased from 34% to 37%,” the minister noted.

Although fatalities among drivers increased from 23% to 27%, there was a decline in passenger fatalities from 41% to 35%. “It is possible to save more lives if more people use safety belts,” Maswanganyi said.

While there was an increase in fatalities among younger drivers between the ages of 25 and 34, there was an encouraging decline in the number of fatalities among drivers between the ages of 35 and 49.

A significant decline was noted among young pedestrians aged 25 to 34, but there was a disturbing increase among those aged 35 to 44.

Western Cape, North West numbers up

The department recorded a noticeable decline in the number of fatalities in seven provinces. However, the Western Cape and the North West provinces recorded increases of 7% and 11% respectively.

Western Cape MEC of Transport and Public Works, Donald Grant, attributed the rise in fatalities in the province to an increase in the number of pedestrians.

“I have asked for geographic information system (GIS) mapping so we can find the exact locations of where pedestrians are being knocked down,” Grant said, adding that 61% of the pedestrians who died in road incidents were found to have ethanol in their blood. “In other words they have been drinking,” Grant said.

The North West attributed the increase in fatalities to focusing law enforcement operations on highways and neglecting rural areas.

The province is planning to construct more speed humps on its roads in an effort to reduce fatalities.

Limpopo, Free State, KZN see figures drop

Limpopo managed to achieve the highest drop in the number of fatalities, followed by the Free State and KwaZulu-Natal.

Minister Maswanganyi said an impressive 43% decline in fatalities was recorded on the top 13 most hazardous routes, with 244 deaths recorded on these roads compared to 429 in the previous period.

Speed and alcohol

While the safety campaign over the festive season focused on drunk drivers, the figures showed a decline in the number of motorists arrested for drunken driving from 5 943 in 2016/17 to 3 301 in 2017/18.

“This is evidence of improved compliance and the success of our messages warning against drinking and driving,” Maswanganyi said.

However, speed continued to be a major headache, with 922 drivers arrested for breaking speed limits, compared to 785 in the 2016/17 period.

Five motorists were arrested in Limpopo, Gauteng, KwaZulu-Natal and Western Cape for driving at speeds exceeding 220 kilometres an hour in a 120 km zones.

Traffic violation notices decrease

The number of traffic violation notices showed a decrease: 453 263 violations were recorded in the previous period compared to 304 603 in the period under review.

There was a decline in the number of people who were fined for failing to wear safety belts and in the number of impounded unroadworthy vehicles.

Learn to speak ‘Engineering’

Engineering jargon can often be difficult to understand, so we’ve listed a few helpful words to keep you in the conversation.

Engineer and SANRAL project manager Thabiso Ngozwana.

Road stud – Not a travelling breeding horse. Commonly known as a cat’s eye, a reflector or a delineator, a road stud is the coloured object (white, red or yellow) attached to a paved surface marking out the road’s centreline and edges. Road studs are a safety measure for people travelling on the roads at night as they reflect vehicles’ headlights when it’s dark.

Shoulder – Not a body part. The shoulder is the area of the road beyond the yellow line. It can sometimes be made of gravel and is used for emergency stops.

Footing – Not something you can lose in high heels. Footing is a flat, shallow foundation for built structures. It serves a similar function to actual feet, providing support and balance. And whether we’re talking about dancing in stilettos or erecting a structure, a firm footing is always required in slippery conditions.

Bedding – Nothing to do with thread-count. Bedding is a specially prepared surface of natural gravel and/or processed material used as a platform for laying pipes and structural components. Typical examples of bedding material are stone, gravel and sand. A good, firm bed is necessary for a decent rest.

Apron – Kiss the cook? Not quite. An apron is a smooth surface, generally made of concrete, between a culvert and the stream channel. It’s meant to reduce erosion and improve capacity.

Slab – Just like chocolate, a slab here is a flat, broad piece of structure. Unlike chocolate, it’s made of concrete or wood and is used as a floor or a roof.

Tar road – There is no such thing as a tar road. No, really. The black sticky stuff used in road construction is actually bitumen, a by-product of oil. Tar, a by-product of coal, was discontinued for environmental and safety reasons a long time ago – it’s carcinogenic and causes warts.

Paving the way for future engineers

Professor Kim Jenkins, the SANRAL Chair in Pavement Engineering at the University of Stellenbosch, writes about the transformative role the national roads agency plays in education.

Professor Kim Jenkins, the SANRAL Chair at the University of Stellenbosch, said the postgrad programme in pavement engineering has gone from strength to strength over the past 17 years.

One of the many valuable statements that passed from Madiba’s lips was: “Education is the most powerful weapon that you can use to change the world.” The world has struggled to internalise and embrace it.

When the South African National Roads Agency (SOC) Limited (SANRAL) decided to depart from investing in inanimate road infrastructure only and turned to funding the Chair in Pavement Engineering at the University of Stellenbosch, it was clear that Madiba’s wisdom had taken root on home soil. This was especially the case given SANRAL’s primary objective of developing human capital and building capacity in the field of pavement engineering.

The inception of the SANRAL Chair in Pavement Engineering in 2001 came at an opportune time, with foundations laid by the preceding pavement academics and Sabita (Southern African Bitumen Association) Chairs at Stellenbosch University. However, only a handful of pavement engineering graduates were being fed into the industry annually. There was a glaring need to create a critical mass of postgraduate researchers. The SANRAL Chair rose to the challenge.

The stimulus needed to get more postgrad researchers involved can be generated in several different academic spheres, attracting experts into the programme from time to time to assist in presenting good-quality courses, innovative research that breaks boundaries and product and model development that benefits industry.

At the same time, a redress of the diversity profile in pavement engineering was required. Through teamwork, the pavement engineering group at Stellenbosch University has managed to achieve growth in the key areas of tertiary education. The growth brought with it unprecedented diversity, both from within South Africa and beyond its borders.

Within five years, the postgraduate profile was transformed from isolated candidates of colour to between 40% and 60% of students emanating from historically disadvantaged communities – a trend that has been maintained for 10-years.

The postgrad programme in pavement engineering has gone from strength to strength over the past 17 years.

Among the defining features is the Chair’s cooperation with international universities in Rwanda, Brazil, China, The Netherlands, Germany, Italy and the US. With regard to outputs, seven doctoral and 51 Masters degrees have been awarded under the study leadership of the Chair. More than 1 000 student courses have been completed in the same period, with the total number of course delegates exceeding 1 600.

Undergraduate activities have also flourished, with inputs from the SANRAL Chair into transportation science, advanced design, research projects and materials science in second- to fourth year courses.

Statistics alone do not capture the essence of an academic chair, nor do they give true meaning to nurturing and mentoring. An old African proverb says “It takes a village to raise a child”.

Within all of the activities of the SANRAL Chair lie mentors who bridge gaps between academic teaching, postgraduate knowledge and undergraduate learning; industry volunteers who present courses, examine theses and moderate standards; industry sponsors and benefactors who help initiate research projects and procure equipment for the university; and students themselves, who volunteer to inform and prepare scholars for careers in engineering.

With such inspiration from our future engineers, there is no doubt of our conviction that the SANRAL Chair will continue to build human capital in pavement engineering.

This is an opinion piece by Professor Kim Jenkins, the SANRAL Chair at the University of Stellenbosch.

Tech teasers: Things to look forward to in the efforts of road safety

Technological developments in improving road safety are leading to newer and better methods of road monitoring.

SANRAL is piloting a panoramic CCTV camera at the N2/ R300 Swartklip Interchange, in Cape Town, which is notorious for high rates of incidents.

The introduction of a panoramic camera and other new technological developments may soon improve freeway incident detection on South Africa’s roads.

The South African National Roads Agency (SOC) Limited (SANRAL) is piloting a panoramic CCTV camera at the N2/ R300 Swartklip Interchange, in Cape Town, which is notorious for high rates of incidents.

The camera uses multiple image sensors and stiches different videos together to get 360° coverage. This is done by analysing the edges of adjacent videos, looking for similarities, and then stitching them together where they overlap.

This technology will give the Freeway Management System (FMS) operator an immersive view of the area.

With increased visibility, operators will be able to monitor the whole area from a bird’s-eye view, providing vital and real-time information to emergency personnel on-scene.

Operators will then also be able to predict potential secondary incidents that may impact traffic flow negatively.

The project is being run by SANRAL’s Technical Innovation Hub.

LEDs better than cat’s eyes

Reflective road studs, known as cat’s eyes, have been used for more than 40 years to improve visibility and provide guidance to motorists travelling at night on South Africa’s roads.

The problem is that they rely on a car’s headlights for illumination. This means they only assist a driver when they are lit up by the vehicle’s headlights. Light emitting diode (LED) road studs, on the other hand, use stored energy to light up in low visibility. Motorists are able to see them up to 1 000m ahead.

LED road studs make use of small solar (photovoltaic) panels to charge during the day. When the light on the panels is reduced at night, during mist or heavy rain, the road studs will turn on. They do not require special timers, reacting to the light conditions in their immediate location.

The use of LED road studs greatly improves a driver’s reaction time to potential hazards or sudden changes in road alignment.

Drones

Engineering-grade surveys can be conducted using remotely piloted aircraft systems (RPAS Photogrammetry) – better known as drones. This allows for the accurate, comprehensive capture of geospatial, topographical and engineering survey data along roads.

This in turn helps engineers design safer roads.

Drones are also well suited for use in the management of incidents that have an impact on roads such as fires, floods and earthquakes. They can assist in the detection, intervention and post-incident monitoring of such incidents.

Because drones can be equipped with all kinds of sensors and equipment such as chemical sensors and infrared cameras, they are also useful in monitoring traffic trends such as the level of service, intersection operations, origin destination flows and real-time traffic data.

The life of a SANRAL engineer

Engineer and project manager Thabiso Ngozwana gives us a glimpse into his work for the South African National Roads Agency (SOC) Limited.

Thabiso wishes he was involved in the building of the Golden Gate Bridge in San Francisco. “It’s such an iconic structure,” he said.

What is the best part of what you do?

The most fulfilling part has to be my contribution to improving the socio-economic conditions of communities. You can often see measurable changes in people’s lives – better houses being built, the presence of public transport where previously there was none, public facilities springing up and the acquisition of cars in the neighbourhood.

What’s the worst?

The worst part of the job is being caught up in project disruptions, which are sometimes due to things that may have nothing to do with the project and are totally beyond my control.

Bridge or intersection?

I prefer bridges. Each one is unique and that’s what makes it special. Bridges have character – that’s why they’re given names. Also, bridges generally have the greatest impact on society, in that they connect communities and provide safe crossings over natural and man-made obstacles.

Which structure in the world do you wish you had designed?

It has to be the Golden Gate Bridge in San Francisco. It’s such an iconic structure. It was known as the “bridge that could not be built”, because of complications like high winds and tides. Plus, it’s beautiful! It’s one of the Seven Wonders of the Modern World and, though it was built way back in the 1930s, it remains a landmark to this day.

Any myths around engineering you’d like to bust?

That engineering is boring and complicated. Engineering concepts are based on the laws of nature and common sense, so it’s not actually that difficult to understand. It involves building things that meet the everyday needs of people – like water, roads and shelter. Engineers are certainly not boring and most of us have a wicked sense of humour.

What made you decide to become a civil engineer?

I suppose it started with a childhood fascination with breaking things down and then remaking them. I used to marvel at all the big earth-moving machines that could literally move mountains and carve order out of chaos. I also began to appreciate the role of civil engineering in the development of society.

What’s the biggest project you’ve worked on for SANRAL?

My biggest SANRAL project is the R61, section 8, from Mthatha to Ngqeleni, worth R550-million. It involved the construction of a dual carriageway road and bridges.

This project, which is in the OR Tambo District Municipality, straddles the King Sabata Dalindyebo and Nyandeni local municipalities (Mthatha being the main town).

So who is Thabiso Ngozwana when he’s at home?

I’m a single parent of twin boys. I enjoy reading news, hiking and watching Formula 1, cricket and soccer. I settled in Port Elizabeth in 2013. I’m originally from the small Eastern Cape town of Matatiele in the western foothills of the Drakensberg Mountains, next to the borders of KZN and Lesotho.

Where did you study?

I obtained a Bachelor’s and Master’s degree in civil engineering from institutions in the US (South Dakota School of Mines) and Australia (University of New South Wales), respectively.

Do you travel a lot for work?

Well, the majority of my allocated projects are in the former Transkei, so I’m on the road for about one week out of every month.
