LETTER FROM
THE EDITOR
Editor • Shani Rhoda
Bridging all sorts of gaps
Everyday on the way to work, I see the infamous unfinished bridge in Cape Town. It stands there, pointless, as a reminder that not everything goes according to plan. But it also serves as a reminder that all things can be fixed. Architecture is possibly the one career field that never fails to blow my mind – it starts with a picture in your mind, you create something bigger and better than what currently exists in that space and you make it happen! You need to choose the perfect materials – ones that are durable enough to last for a lifetime (or longer) – and bring a dream to life. Whether it’s a home, a school or a skyscraper that’ll enable corporate companies to pump billions of rands into our economy, your creation will be a safe haven that enables magic to happen. In this issue, we explore magnificent bridges that cross borders and unite two countries on p20. We also take a look at how architects and constructors are putting nature first by considering the natural environment in their designs and incorporating the elements to make a self-sufficient building. Turn to p16 for more on this. Did you know 3D printing can create a home?! On p23 we touch on this amazing new world made possible by technology.

A GLIMPSE INTO SOUTH AFRICA’S ARCHITECTURAL HISTORY With over 21 000 sites and structures that have been identified as historically significant, we take a look at our country’s rich history and explore whether Africa is ready to ride the smart-city bandwagon.

istory is apparent as you walk down the thousands of streets of the rainbow nation country that is filled
with layers of cultural landscapes and varied architectural tradition. While some buildings, spaces and towns in South Africa have hosted dramatic changes through time, numerous streets retain the imprint of several architectural developments from as early as the 16th century.

Internationally, Melbourne, Singapore and India, among others, have embraced this way of living and their governments have geared up to optimise their resources and create connected cities that can grow sustainably while improving the quality of life of its citizens. With Africa’s population rapidly growing (according to the UN, it is expected that the total population will have doubled to 2.4 billion by 2050) this means tremendous pressure will gradually be placed on the resources of urban centres. We asked South African architect and urban planner Inam Kula whether Africa is ready to jump on the wagon of smart cities. "There is no doubt that the fourth industrial revolution is upon us," she says. "However, we always need to remain cognisant of context and be conscious of the fact that smart cities will manifest differently in cities of the global South vs. cities of the global North.” "Although the first wave of urbanisation occurred in the global

Making headlines Here are the stories making local and international news. And the 2018 Nobel Prize goes to… James Allison and Tasuku Honjo! The pair, from Texas MD Anderson Cancer Center in Houston and the University of Kyoto in Japan respectively, was jointly awarded the prize in Physiology or Medicine for their work on using the immune system to fight cancer.
Just whizzing by Viral videos circulate the internet all day, everyday. But videos of 10-year-old maths masters do not. Local maths whizz Sbahle Zwane made an impression when a video of him solving complicated problems (and earning a quick buck off it!) did its rounds on social media. And his potential was recognised when he received a scholarship from independent school Curro … plus, his single mother was offered a job at the school!
Creating a solid flow A study conducted by civil engineering students at the University of Cape Town (UCT) found that human urine could be used to create a bio-brick – the world’s first of its kind! Supervisor Dr Dyllon Randall, honours student Vukheta Mukhari and master’s student Suzanne Lambert unveiled the first brick. A natural process called microbial carbonate precipitation was used to produce the bio-brick. We hope this leads to many successful buildings in the future!
The next big, blue thing It’s predicted that the next major contributor to South Africa’s GDP will be the blue economy. In addition to creating job opportunities, sectors including fishing, aquaculture, oil and gas, shipping, mining and coastal development are expected to contribute up to R177 billion to the country's economy by 2030.
Changing climate change The recently-launched Shallow Marine and Coastal Research Infrastructure (SMCRI) at Nelson Mandela University’s Ocean Sciences Campus in Port Elizabeth aims to highlight the general understanding of the impact of climate change. The SMCRI is a project of the university, the Department of Science and Technology (DST) and the National Research Foundation (NRF). The iniative seeks to research South Africa’s shallow coastline. "In the development of the 'blue economy', the exploitation of living (fisheries, aquaculture, tourism) and non-living marine resources (oil and gas, minerals, energy) should be on a scale that is socially and economically justifiable and ecologically sustainable," said DirectorGeneral of Science and Technology, Dr Phil Maura.
My way on this highway! A R1.4 billion architectural and engineering project was recently completed in Durban – Africa’s longest flyover bridge that stretches for 1km. The Mount Edgecombe highway interchange was officially opened to traffic by transport minister Blade Nzimande and the South African National Roads Agency (SANRAL). The development hopes to ease traffic in the area.
Safe food for all Following the recent deadly listeriosis outbreak, measures have been put in place to ensure that the food being sold is safe to consume. One of these measures is the first Centre for Food Safety to be opened in South Africa. The centre is a collaboration between Tiger Brands and Stellenbosch University and aims to refine the existing food systems in the country.

“Every successful company practises a culture that is based on a set of founding values. By the same token, I believe that most successful people in various disciplines (especially those in leadership positions) have established themselves by following a set of values in order to achieve their goals,” says Sibongiseni. “For example, Nelson Mandela dedicated 67 years of his life committed to and realising the dream of a non-racial, non-sexist, peaceful, united and prosperous South Africa. The best way to honour his legacy is to uphold the values, ideals and principles that he stood for.” “This got me thinking about my own values and I realised that living a healthy lifestyle is something that I aspire to.

It's important to remember that I cannot protect my family without protecting myself and I cannot care for my family without taking care of myself. Current advancements in many fields (especially technology) have made change more imperative in recent times. As we learn new things daily, we also need to unlearn old things that no longer serve us well. Our beliefs or abstract principles are projected to us mostly by culture systems as we grow older. To formulate solid principles to live by, it is imperative to scrutinise the values and concepts or beliefs upon which culture in one’s environment was formed. Different cultural norms followed in various environments influence peoples’ personalities differently. It's important to be open-minded and embrace diversity as you get exposed to different cultures. I believe that if I follow my own solid principles that I have tested through experience, then I can achieve anything that I set my mind to – and so can you!”

Mokena Makeka A peek into the work of an award-winning architect and designer. By: Nicole Ludolph Makeka and his architecture firm have received a number of awards, one of which is the Gold Loerie Award for Communication Design in Architecture in 2011. They won this award for their work on the SAPS station in Retreat. They also won the Cape Institute of Architecture Merit Award for the Khayelitsha Multipurpose Centre in 2009. In 2010, Makeka sat on the FIFA World Cup Arts & Culture Task Team. He does not just limit himself to architectural design, however. He also takes time to pass his knowledge and experience on to others. He lectured locally at the University of Cape Town, and internationally at Columbia University School of Architecture.

Makeka graduated from the University of Cape Town in 2001 and started Makeka Design Lab the next year. With roots in Cape Town, his notable works include the refurbishing of Cape Town Railway Station prior to the 2010 FIFA Soccer World Cup, as well as the Khayelitsha Multipurpose Centre and the redesign of the South African Police Service (SAPS) station in Retreat. In a 2014 interview with FreundenVonFreundon.com, an online platform connecting those in the creative community, Makeka compared architecture to music. He described architecture as moving through a space “forwards or backwards, it’s always changing, its character is consistently shifting. You can design architecture but you can’t really control it. It’s also about how people interact with it.”

IDENTITY IS IN THE
EYE OF THE BEHOLDER “Dare to be different, but at the same time, stay true to yourself.” GUGULETHU MABUZA-HOCQUET These are very appropriate words indeed from the woman who has committed her research to identity protection. The way Gugu sees it, your identity is all you really have – and the answer to protecting it, lies in iris biometrics. She is exploring the unique iris properties of the South African population that may just hold the key to a uniquely South African security encryption system. “Your iris does not only hold information such as your age, gender and race, it also says you are part of a demographic mix that is not found elsewhere in the world. Now imagine a future where those unique features in your eyes will protect the most valuble thing you have – your identity.” Gugu describes the way she ended up in science as a “beautiful accident”. It’s certainly one to be thankful for.

FACTS
Bet you didn’t know that… • The Bridge of Eggs in Lima, Peru, was built using mortar that was mixed using the whites of 10 000 eggs instead of with water. What’s even more unbelievable is that the bridge still stands today! • Ten million bricks were used to build the iconic Empire State Building in New York. • A team of 400 000 men spent twenty years building the Great Pyramid in Egypt. • The Great Wall of China is visible from space – it’s the only man-made structure that is. • The construction of the Unfinished Foreshore Freeways in Cape Town was stopped in 1975 mostly due to budget constraints. • The Taj Mahal in India has been exposed to damage and discolouration due to the air pollution caused by nearby factories and the amount of insects from the polluted Yamuna River. The damage is so bad that the Supreme Court threatened to close it down or even to demolish it! • The world’s tallest building, the Burj Khalifa in Dubai, is a whopping 828m high – three times the height of the Eiffel Tower. • The largest underwater restaurant in the world, named Under, is currently being built in Norway. The restaurant will also be used as a sea lab where marine biologists can observe marine life. • English architect Herbert Baker designed Rhodes Memorial in Cape Town and The Union Buildings in Pretoria. • Cape Town’s most expensive parking bay – a basement bay in Clifton – was bought for R2 million in 2008!
