There’s an art to making roads safer

The drive to promote road safety continued with the 2nd annual Chekicoast Art Competition, which announced its young winners yesterday. The winners created pieces that helped teach the rules of the road, and how better to navigate them safely. In fact, part of the judging criteria for the competition was using the correct traffics signs and signals!

The youngest winner was nine year-old Avuyile, from East London. Her winning work focused on how the road belongs to everyone; making it everyone’s responsibility to look out for each other. She, and all the other winners, got a R5000 gift voucher.

The Grade 4 to 6 category was won by a young man who’s had success in art competitions before: twelve year-old Durban native, Abhay Charan Jalim. Despite having limited access to art resources, Abhay has found ways to express himself in vivid colour.

Just south of Bloemfontein, in a special art studio run by learners for learners, is where we find our next winner: 16 year-old Keitumetse Motshwane. He decided to enter the competition as he was concerned by high road deaths. His solution, (other than art)? More traffic officers; a profession he wants to pursue.

Finally, aspiring jewellery designer, Gabrielle Lourens took the Grade 10 to 12 prize. The young woman from Pretoria, who is now chasing her dream at TUT, is passionate about teaching road safety habits to young people. And she thinks art is the perfect way to do it.

We agree, which is why next year’s SANRAL Road Safety Art competition will open soon, with a new category for older students. Keep an eye peeled for more details.

SANRAL R150m R71 Upgrade eases congestion during Easter

Exactly a year ago, if you were travelling on the R71 interchange towards Moria, the challenges you’d be met by would include constant congestion — resulting from a clogged-up two lane road running from Polokwane to Tzaneen, and consequently, a single lane for traffic coming from the opposite direction. This traffic jam would reach its peak around Easter time, when millions of pilgrims assemble at the R71 interchange to access Moria, their central place of worship.

This would be coupled by a host of unavoidable road safety risks, as cars wanting to make an intersection from the interchange into Moria would do so purely at their own risk — without a guidance system or traffic control measures. To add insult to injury, you’d have to be vigilant of the thousands of pedestrians alighting minibus taxis, a factor which has contributed to the growing number of pedestrian fatalities. But this was 12 months ago, and the situation has improved dramatically, thanks to the intervention of the South African National Roads Agency of Roads, generally referred to as SANRAL.

Costing R150 million according to Billy Law, President Engineer of SNA Civil & Structural Engineers, the R71 bridge construction has alleviated the congestion significantly and has been met by great jubilation by both ZCC congregants and local residents of Limpopo: for the former, alleviated congestion means pilgrims can make the mission to Moria more quicker and safer; for the residents, new jobs have been created, reducing the unemployment and the resultant crime.

The R71 bridge construction milestones were achieved jointly by the construction of a dual carriageway, a widening the road, and a road overlay. Furthermore, a pedestrian walkway was constructed for pedestrians at the shoulder of the interchange to provide easy access to pilgrims accessing Moria.

SANRAL Project Engineer, Riaan Oerlemans, is happy with the operational tempo and cooperation at the site, and by the fact that they were able to meet their Easter deadline.

Louw Venter, the Contracts Manager for Hillary Construction, said the old intersection was a level ground intersection, and the new one is a free flow intersection with a bridge that leads to the church and a temporary road that offsets the interruption of the general traffic.

Through this project, SMMEs (Small, Medium and Micro Enterprises) were involved in the upgrade of the interchange, of which six were black owned. The anticipated spend of SMMEs is R9 120 000.

Building a brighter future

SANRAL - Derusha Govender
Derusha Govender

For a nation to succeed, you must do more than just build up its infrastructure. You need to develop its people. That’s why, for the last 8 years, SANRAL has helped 89 young South Africans follow their passions with educational bursaries worth R7.7 million. Of the 19 students who graduated in 2014, six have gone on to work with us at SANRAL.

Like the passionate Derusha Govender, who sees every challenge as an opportunity to grow. She’s currently applying her new engineering expertise on the N2 Mt Edgecombe project.

Or Daniel Govender, who pursued civil engineering honours, because he wanted to be involved in every step of a project, from design to construction.

Sasheen Rajkumar isn’t just grateful for the opportunity he’s already received, but sees working at SANRAL as continuing his education by exposing him to their vast infrastructure experience.

Finally, Limpopo-born Fulufhelo Luruli wouldn’t have been able to live her dream of becoming a civil engineer without assistance from SANRAL. But now she’s chasing her Masters, while still working on the huge projects.

All these and more proud bursary students are working to give back to South Africa, and building a brighter tomorrow.

Summertime and the road is easy

For many of us there is a constant and familiar itch to hit the road. Whether it’s to visit loved ones that we don’t get to see enough, or fleeing home and heading to the beach or mountains or somewhere in between.

A popular travel writer whose blog I frequent recently wrote that his favourite part of travelling was the period in-between destinations. That may seem strange for someone with the enviable job of writing extensively about different settings, but his reason was intriguing.

He said that despite the excitement of experiencing a new destination, nothing beat the anticipation of what is to come – before expectations are not met, like the disappointing weather or finding out that your accommodation is facing a popular (and very loud) local nightspot.

I would have to agree. Apart from seeing loved one’s faces and sharing new experiences together, some of the best moments of a road trip, after the planning, scheduling and the counting down to D-day, is the journey getting there, and the intoxicating nostalgia that this invokes.

Who doesn’t have fond memories of early morning call times, food laden cooler boxes being packed into car boots, the travel pillow which will soon be fought over, and the wonderful excuse to eat greasy burgers (or anything really) at 10am in the morning.

While every family has their travel rituals, there are always common pleasures that all good journeys share.

The more the merrier

Travel provides time for family, and nothing says family- time like successfully packing multiple children, a teen or two, and grandparents into one car. The best part of all is that you actually get to spend time with the family.

Being confined in the car forces you to be present, which doesn’t happen too often in our everyday lives with never ending to-do lists. On the road you only need to focus on keeping fed and entertained.

When else are you going get an opportunity to share travel titbits like: there are exactly 10 overpasses on the N5 between the little town of Kestell and Bloemfontein, or that South Africa has the longest wine route in the world, the R62 wine route.

You can also use the opportunity to teach little ones how to play a game of I-spy, or make up your own, such as trying to guess the destination of fellow travellers from clues like motorboats and mountain bikes perched on the roof, or beach umbrellas poking through the back window.

Rest and relaxation

Successful pit stops achieve two very important tasks: first, to revive the body – stretch the legs, breathe in some fresh air, and if you are lucky, sink your toes into the tiny patch of grass in the kids play area.

Pit stops are also a culinary adventure. Whether you bring your own padkos tucked away tightly in steaming containers, or choose to sample the limited but plentiful offerings that the fuel stops along the way have to offer, what’s standard is that all diet restrictions, and sometimes good sense, is happily abandoned. Suddenly coffee can be consumed at all hours of the day, slap chips become a food group, and snacks like fruit and nuts make way for ice-cream, biscuits and gummy sweets.

Leaving space unexpected

Spontaneity thrives in the absence of deadlines and everyday pressures. Most of the travelling we do is pretty straightforward simply because there isn’t enough time to explore and let loose.

But weekend breaks and mid-year getaways afford us the luxury of taking the longer but more scenic route, to accept that invitation to share a meal with the family on the next table, or to finally make that stop in Bloemfontein you have been meaning to make for years. And it has never been easier to explore the unfamiliar. The beauty of smartphones and a GPS is that it is almost impossible to get lost and you are able to research as you go. Who knows what treasures are waiting for you when you take that sho’t left?

Happy travels, keep safe and remember, you are only a few hours from an adventure.

Engineering approaches to concrete bridge repair and protection

On 5 March, SANRAL project managers, Edwin Kruger and Ravi Ronny held a seminar on the concrete Repair and protection titled “the good, the bad and the ugly concrete structures.”

Normal design life is 50 or a100 years for a bridge. If a bridge is built for a mine that only has a life of 10 years then durability is not considered a high priority- only coast- and that is a mistake.

Environment is influenced by what is left behind even when a project has served its purpose. Engineers have an ethical duty towards society.

Causes of defects

  • Bad initial design and detailing
  • Bad construction
  • Lack of attention to durability of concrete materials used at time of design and construction
  • Accidental damage – over-height vehicles
  • Extreme weather or natural events like earthquakes

SANRAL uses a standard tender document for tenders for diagnostic tests depending on the extent of repairs required. Testing could also include for concrete strengths and cover tests.

Rehabilitation

SANRAL developed standard specifications for repair of structures as series 12000 that relates to concrete repairs and is comprehensively detailed. Performance specifications are now the norm for SANRAL in which contractors have to supply performance guarantees.

Concrete protection

Very old concrete showing signs of distress, carbonated or chlorinated concrete needs protection. Coating with a silane penetrant coating and not barrier coatings generally improve this. Barrier concrete must breathe as they provide protection and aesthetics, often have maintenance problems in the long term if not properly fixed.

Lessons Learnt

  • Use far less barrier coatings in the future for carbonated concrete
  • Use of silanes/ siloxanes instead of barrier coatings in certain applications
  • Drawings must be complete before project handover to contractor. Lead times to allow for testing needs to be increased.
  • Get guarantees early in contract. If necessary, withhold payment.
  • Limited extended life before further repairs to 15 years is now requested to avoid “Rolls Royce” solutions. Client must accept the risk.

Conclusion

  • Our defects-based BMS has proved effective in prioritization
  • Performance guarantees for products results in a more positive approach
  • Emphasis now on durability and not strength only
  • The cost of associated items such as traffic accommodation and access contributes a large percentage of repair costs
  • Hopefully less future maintenance on newly built structures
  • Having performance criteria for asset preservation built into strategic objectives ensures that bridges do get repaired
  • Aesthetics is important to the public

Hopefully there will less of this:

To quote from Dr. Konrad Lorenz, the eight deadly sins of a civilized man states that “the beauty of nature and the beauty of the man-made cultural environment are apparently both necessary to maintain man’s mental and physical health.”

Building dreams through roads

“Education is the most powerful weapon which you can use to change the world.”– Nelson Mandela.

Helping others ends up as helping yourself and this could be a way to describe what the country’s road agency does in the field of education. You may ask yourself, what does a road agency have to do with education?

South Africa needs engineers, so does SANRAL and that is a common interest they have. The agency has stepped in to assist with full bursaries and internships and in this way it helps itself as well as the country.

Mercy Masia, a Wits University Senior Student is pursuing her objective of becoming a civil engineer, and a beneficiary of a full SANRAL bursary. Masia says she thoroughly enjoys the workshops arranged by the agency as they provide her with the practical insight and the experience required for her future career path.

The biggest challenge Masia is facing is to ensure that all her work gets done in time. Although she enjoys recreational reading, she often reads her textbooks for the coming semester during holidays so she can get ahead and be prepared.

A true athlete at heart, Masia enjoys participating in sport. Her advice to anyone who wants to follow her path is “use every minute.” She emphasizes that it is very important to get as much as possible, and time must never be wasted if it can be used in a constructive manner.

Internships provide vital work experience

ER scholarship induction

Practical experience is an important factor to gain skills and more opportunities in different industries. As such, SANRAL provides internships to engineering students at various institutions in South Africa to equip them with practical work experience as required by the degree curriculum.

This programme is implemented in cooperation with contractors and consultants working with SANRAL. In the 2013/14 financial year, 196 students received internships and vacation jobs from the agency and 17 were employed by SANRAL and its stakeholders, including companies, contractors and consultants. This represents an increase of 5% compared to the previous financial year.

In terms of a performance agreement between SANRAL and the Minister of Transport the number of internships offered should be equal to 10% of staff complement. However, because of the high demand for practical experience within the engineering fields SANRAL has exceeded this requirement and now offers internship opportunities equivalent to 70% of the agency’s staff complement.

New Route to provide safety and comfort to road users

Travelling between Kwa-Zulu Natal and the Free State is often a difficult journey, especially due to traffic. But all that may change, as SANRAL has endorsed a new project aimed at increasing higher levels of comfort and productivity for all road users.

The De Beers Expressway was highlighted at a media site visit on 26 February. The proposed route is set to significantly ease the congestion on the current Van Reenen’s Pass route and will result in higher levels of safety on the road.

Adjustments to the route

SANRAL’s general communications manager, Vusi Mona, said that should the Expressway be constructed:

  • It will be an entirely new stretch of highway across the Drakensburg escarpment in the vicinity of the existing Van Reenen’s Pass.
  • It will be a 99 kilometre four-lane highway that will link Keeversfontein (Tugela Toll Plaza) in Kwa-Zulu Natal with Warden in the Free State province.
  • The convenience of the new route is that it will be 15 kilometres shorter.
  • Its grades will be much flatter and its alignment will be smoother without the sharp and numerous curves of the existing N3 route.
  • Much time will be saved and better levels of service will result in improved safety and a reduction in accidents.

The Van Reenen’s Pass route was built in 1961 and can no longer effectively handle the growth in traffic volumes. In recent years, the number of accidents on the route has increased, resulting in scores of fatalities and road users being inconvenienced through sporadic road closures.

n3-814-8 n3-814-56 n3-813-167

Accidents and road closures are regular occurrences on Van Reenen’s Pass due to the steepness of the road and the sharp curves. It is hazardous to drive during cold and wet weather.

Mona added that total closure time increased from just less than 80 hours on the southbound road in 2011 to 95,6 hours in 2013. On the northbound round, this grew from 88,25 to 102 hours. The economic impact of road closures translates into tens of millions of rands.

The N3 route has been identified as one of the priorities of the multibillion rand Strategic Infrastructure Project and is crucial to unblocking economic development and providing much needed capacity along key freight corridors in South Africa.

Construction of the De Beers Expressway route is crucial to plans to develop the Durban-Free State-Gauteng logistics and industrial corridor, which is vital to the future of the national and regional economies. This new project would not result in additional toll plazas along the N3.

Durban handles over 40% of the country’s imports and exports, and Gauteng, being the country’s economic heartland, generates over 33% of the country’s GDP. The Durban-Free State-Gauteng corridor is by far the most important economic corridor in the country and this new route would directly contribute R4,4 billion annually towards South Africa’s GDP.

The beauty of SA’s largest province

The largest province in the country boasts the brightest stars, once a year spectacular flowers and wildlife which includes the black-maned lion.

If that sounds like a romantic or family getaway to experience, it is time to take a tour in the Northern Cape.

With space aplenty, long road trips to enjoy and the warm to summer days and cold winter nights the Northern Cape is a true escape from the hustle and bustle of major urban areas.

The N14 runs from Springbok through Upington via Kakamas and ends in Gauteng – most of the provincial tourist highlights can be reached off these maintained highways such as the Kgalagadi Transfrontier Park. The 37,000 kilometres stretch across South Africa and Botswana and there are plans to link this huge park to the nearby Augrabies National Park and the Namib National Park, which is the largest conservation area in the world.

Northern Cape heritage offerings:

The Kgalagadi

• You can feel the peace descending on you as you gaze at the red sand dunes.
• There is sparse vegetation, the occasional tree and dry riverbeds, the gemsbok and the black-maned lion.

The Augrabies Falls

It is where the water thunders through a gorge and makes you feel small and vulnerable.
There are several kinds of buck as well as small predators like leopards and wild cats and a rich offering of indigenous plants.

UNESCO Heritage Site, the Richtersveld Cultural and Botanical Landscape border on the Ai-Ais Park in Namibia and enclose the world famous Fish River Canyon.

Namaqualand is known for its stunning display of wild flowers between July and September, becoming a massive carpet stretching to the horizon of scent and colour.

Wild flowers

And the provincial capital, Kimberley, has a fascinating history built around it and South Africa’s earliest diamond days. Not forgetting the Big Hole, which is the biggest man-made in the world because of its diamonds.

We can go on and on about the Northern Cape, so journey on and experience it and frame those memories.

Trout in Limpopo saved by a better road

“As members of the trout family, we would like to thank SANRAL for saving us from the disruption of the environment on the R71, where our home is underground, during the rehabilitation of this road in November last year.”

The project of the road was a relief for motorists travelling between Moria and Tzaneen in Limpopo. SANRAL was asked to take control of the road rehabilitation on the major regional road.

It was a section close to the Stanford Lake College and raised environmental concerns. For the trout, a fish ladder has also been completed so that they can survive. However, upgrading the bridge meant that the trout would be cut off from their spawning grounds.

SANRAL’s communications manager, Vusi Mona, said the importance of trout fishing for the whole Haenertsburg/Magoebaskloof area meant a fish ladder had to be added.

Trout travel downstream during their lifetime but return to their place of origin when breeding. The water under the bridge was very shallow and when it spreads out, they won’t be able to swim upstream.

Silence on the road surface please

With so many cars on the roads, it is without a doubt that noise pollution is one of the greatest factors that should be addressed in exchange for silence.

This kind of pollution contributes a large share in developed and developing countries, though it is a multi-faceted one which warrants an approach beyond what the road agency, SANRAL, can offer.

But road noises, however, do not only come from the road surface, but tyre types, roadway geometrics, speed and vehicles all contribute. Roads with rough surfaces are noisiest, while asphalt is quieter and smoother by comparison.

SANRAL undertook an investigation into seal types that could potentially reduce noise, with the intention to use the resulting information to lay down guidelines for selecting the type of seal that ought to be used in built-up areas.

The tests were carried out on two sections of road in Cape Town. The first section; four types of seals were selected and the second set of tests were carried out on existing roads with different surfaces.

It was then found that there is no standard surfacing that can result by itself in a noise level low enough to meet national and international guidelines. Additional measures would have to be taken on high-speed urban highways. Further tests to look for a standard paved surface would have to be taken.Road2

Vusi Mona, the agency’s communications manager, says they hope to have an answer soon but implementation will be a drawn out process, as a wholesale difference cannot be implemented overnight.

This confirms that SANRAL commits itself to building excellent roads and taking the communities around its highways into account.
