Solar Cities

In 1839, Alexandre Edmond Becquerel discovered electricity could be generated by sunlight. He claimed that “Shining light on an electrode submerged in a conductive solution would create an electric current.” Solar energy is now utilized and recognized all over the world.

Solar cities would be very beneficial in South Africa due to our current restraints with Eskom and the load shedding each one of us has had to endure on and off for the past 12 years. Solar Energy is free and being a third world County, this would be viable and It would be great not having to depend on Eskom for electricity.  Utilizing Solar panels will save you money and reduce your lights account.

Many South African are currently utilizing solar energy to power the following:

  • Watches
  • Calculators
  • Lighting
  • Water pumps
  • Water heaters

Solar energy hold’s the most potential in South Africa due to the fact that we receive a large amount of radioactive energy. Solar Energy is renewable, meaning we will never run out of sunshine. Wind energy could also be unitized in South Africa, especially around our coastal areas.

Counties that make the most use of Solar power would be:

  • China
  • United States of America
  • Japan
  • Germany
  • India
  • Italy
  • United Kingdom
  • Australia

The initial cost of setting up a solar running house or city is at a high rate, however, the saving, in the long run, is thousands of rand.

How Factories are Constructed

posted in: General 0

A factory is an industrial site, usually consisting of buildings and machinery, or more commonly a complex having several buildings, where workers manufacture goods mostly in bulk or operate large machines processing one product into another.

Factories are normally large buildings with a lot of empty space to work with as well as your different sections with different machinery for the different stages of production

When building a factory there are a few points to keep in mind. Factory layouts and designs require detailed coordination between the manufacturing process, production line and building facility.
The floor load, headspace, bay size and more all depend on the type of machines and equipment to be used.

5 common types of factories

  • Chemicals
  • Food Production
  • Electronics
  • Paper
  • Metal manufacturing

The first factory was built in 1790 by Samuel Slater in America

The largest factory in the world is the Boeing Everett Factory situated in Washington, with a surface area of 398000m2 and was built in 1966

Daily technology, as well as the designs of factories, are developing and changing. In the near future, we will see people working together with intelligent machines, also factories who are highly contributing to our environmental pollution are changing their ways for the environment and these are the factories of tomorrow.

Tallest Buildings in South Africa

Tall, Taller, Tallest… The 5 tallest buildings in South Africa.

South Africa is one of the most structurally and economically developed nations on the African continent.

Let’s have a look at the top 5 tallest buildings in South Africa.

Interesting Facts:

1. The Leonardo is a 55 Floor mixed-use property development reaching 234m.

Its completion in 2019 has made it South Africa’s tallest building, taking over from the Carlton Centre which was the tallest building since 1973. The development will include street-level shops as well as an above-ground podium, where a swimming pool, restaurant and several other facilities will be located. The tower portion of the development will be built above this 4 level podium. An alternative name for the development was 75 on Maude. However, it will only hold that title for a short duration, as Kenya has plans to build the tallest building in Africa within the next three years.

2. The Carlton Centre is a skyscraper and shopping centre located in downtown Johannesburg and reaches 223m and 50 floors.

The Carlton Centre was designed by the US architectural firm Skidmore, Owings and Merrill. Anglo American Properties began construction in the late 1960s by demolishing the old Carlton Hotel and the closing roads to form a city superblock. Excavations for the Carlton began in January 1967 and took two years to complete. Although occupation of the Centre began in 1971, construction was not finally completed until 1974. The building officially opened in 1973 at a total cost of over R88 million

3. The Ponte City Apartments is a skyscraper in Berea, Johannesburg.

It was built in 1975 and is 173m and 55m, making it the tallest residential skyscraper in Africa. The 55-story building is cylindrical, with an open centre allowing additional light into the apartments. The centre space is known as “the core” and rises above an uneven rock floor. When built, Ponte City was seen as an extremely desirable address due to its views over all of Johannesburg and its surroundings. The neon sign on top of the building is the largest sign in the southern hemisphere and advertised for the Coca-Cola Company prior to 2000. It currently advertises the South African mobile phone company Vodacom.

 

4. The Marble Towers is a skyscraper in the CBD of Johannesburg.

Built-in 1973 and is 152m and 32 storeys tall. The structure is made out of a mixture of concrete and marble and has an eight-storey parking garage attached. The building was originally known as the Sanlam Centre. It is located on the corner of Jeppe and Von Wielligh Streets.

 

5. The South African Reserve Bank Building is a 38 storey skyscraper in Pretoria.

It was built in 1988 and is 38 storeys tall. The structure is made of concrete and glass and was the first flush glazed glass tower block in the Southern Hemisphere.

How to Go Green without Breaking the Bank

posted in: General 0

How to go green without breaking the bank does not necessarily mean smoke and fly.

Going green means being environmentally responsible, eco-friendly and can be affordable.

You do not need to drastically change your lifestyle right away. You can start gradually by doing just a few things and adding more as time goes on. Depending on what you do, your actions will help the environment in many different ways, but they will all add up to help reduce the impact of climate change.

1. The home set-up
Your home should be set-up in a way that saves energy.

  • Plug home electronics into power strips; turn the power strips off when the equipment is not in use.
  • Install low-flow showerheads.
  • Use Energy Star-qualified CFL and LED bulbs.
  • Install outdoor solar lights
  • Make your own detergents.

2. Food options

  • Consider turning your backyard into a miniature garden.
  • Make your own compost.

3. Thrifting everyday purchases

  • Spend a weekend thrifting or even visiting vintage shops to find cheaper and green alternatives.

4. Selling and donating unwanted items

  • No matter how organized you say you are, everyone has some level of clutter.
  • Start by taking a look in your closet, picking and packing the items that you have not worn for ages.

5. Reduce, Reuse, Recycle

6. Plant a tree

7. Use Less Water

8. Bring bags to the grocery store

9. Check out Freecycle

  • One man’s trash is another man’s treasure is the cliche behind Freecycle
  • Check your local board on the site to search for household items, from furniture to technology, that other people want to give away. The site is also perfect for getting rid of your own useless junk. Freecycle is free to join (naturally), and it’s a win for both you and the environment.

10. Ditch your car.

  • If you can get to work without driving, why not do it? You’ll get some exercise, save some cash and help the environment. Even better, it will make you happier and generally more satisfied with life.
  • Carpooling.

Safety shouldn’t be Complicated

Safety (noun); the condition of being protected from or unlikely to cause danger, risk, or injury.

Safety really should not be complicated. Sometimes taking all the safety precautions can end with injury and in some extreme cases, even death.

Some examples spring to mind…
20 years or so ago, my school friend was travelling from Durban to Pietermaritzburg with her father, and they had an accident. Emergency personnel could not free her from her safety belt, and she ended up being burnt to death.

In some other cases, some people might still be alive if they had their safety belts on, which would have stopped them getting ejected through the windscreen. Buckle up and maybe carry a knife on you just in case you need to free yourself.

Then there are a couple of cases where timber workers, felling trees, end up with the tree falling in the wrong direction, or maybe they were just standing in the wrong place at the wrong time and got hit by it; instant death. Protective clothing and helmets did not help in these cases, but maybe if they had a better knowledge or were more aware of their position, they might still be alive.

Whilst you may have heard of these safety rules before, some do need repeating:

  • Stay alert and stay alive. The more awake you are, the less likely you will get hurt. I don’t know how many times I have driven on the N3 and seen trucks overturned. Rest when you feel tired. Rather get there alive, than in pieces.
  • Wear the correct clothing. Protective clothing should fit properly. Wear your protective helmet. You never know when an accident may occur. Be prepared.
  • Use the right tools. If you need a spanner, use it. Using incorrect equipment is just asking for trouble.
  • Don’t play pranks. Practical jokes can be dangerous, especially around heavy machinery.
  • Be tidy. This will reduce hazards. Always put your tools away when you are not using them and keep your floors clean and clutter-free. A slip or fall may just end up being a hospital call.
  • Do not take chances or shortcuts. Do it right, and do it safely. Short cuts are probably the biggest killer of all. To save a minute or two, you may lose a life.

If you follow all the safety precautions and still end up getting hurt, get first aid immediately. Neglect of an injury could lead to infection, loss of work time and in some cases, permanent injury.

Remember, your safety is your responsibility. If you are in doubt, contact your supervisor or manager for instruction, guidance, or training.

Safety is not complicated, but it is a choice. Choose wisely.

Essential Tips on Pest Control in Construction

posted in: Did You Know, General 0

The best way to treat pests is prevention before construction, rather than managing a problem that arises after your building has been standing a while when prevailing conditions could result in an open invitation to pests. This may pose the threat of them making a home within your building, or neighbouring buildings. The damage that little critters cause, without one even being aware there is a problem, is substantial. Infestations can prove more costly to eradicate than preventative solutions. There are ways and means to avoid the unwanted attention of pests throughout the construction process, but the bottom line is to build pest control into your construction plans as early as possible.

See below for a 4 step strategy for successful pest control.

1. To establish the best pest prevention methods it will be vital to establish the following:
What kinds of pests pose threats in the area of the site and how high risk do they pose (types and numbers)
What routes might pests use to enter the building
How the building is constructed (to avoid high humidity, accumulation of water, or contact between timber and soil)
What materials are being used in construction such as timber and other permeable building materials, opting rather for impermeable materials such as brick, stone, concrete, and steel

2. Assess the risk of pests in the site location:
Monitoring – To assess types and numbers. Monitoring could be in the form of traps, inspections, and sampling or visual counts to assess the patterns of pests in the area. Monitoring can be done continuously through all stages of construction and as a management tool post-construction
Water Sources – What nearby water sources are there such as ponds and lakes which could pose a threat as pests will locate their nests close to water sources.
Grading – If your property is not appropriately levelled or graded, water may pool in areas of the site, attracting termites, mosquitoes, and other pests.

3. Formulate an adequate plan to prevent and manage pests:
The plan should not be an isolated pest control method but rather a combination of a number of control methods based on various factors and the information obtained through the above assessments, together with ongoing monitoring and reports.

Control methods to remove pests include:
Non-chemical
Pest trapping
Heat/cold treatment
Physical removal
Chemical
Pesticide application – a chemical treatment helps to form a protective barrier against later infestations
Control methods to avoid the influx or return of unwanted pests:
Training of construction workers, and the staff who will later occupy the building in the importance of sanitation and pesticide safety. Unhygienic practices and conditions will encourage the inhabitation or re-inhabitation of pests.
Inspection of all building materials that enter the site during construction
Reducing debris and clutter around buildings, the removal of litter and overgrown vegetation, and keeping planting away from the perimeter of the building will all discourage pests from settling
Sealing areas where pests enter the building
Installing traps, pest barriers and repellents
Maintaining clean dining and food storage areas

4. Documenting pest control actions is helpful in the evaluation of the success of your plan:
Record of each pest control method, including pesticide applications
Evidence that non-chemical control methods were considered and implemented where possible, due to the toxicity levels of pesticides.
Recommendations for preventing future pest infestations

Finally, to ensure continued pest prevention and control, it is advisable to work with a pest management professional on a regular basis and to keep your prevention and management plan relevant and current.

Why you should safely dispose of Asbestos

posted in: General 0

Firstly… let’s start with understanding what asbestos is. 

Asbestos is a term used to refer to six naturally occurring silicate minerals. All are composed of long and thin fibrous crystals, each fibre is composed of many microscopic ‘fibrils’ that can be released into the atmosphere by abrasion and other processes. Asbestos fibres are naturally resistant to heat, fire, electricity and chemicals and use to be used extensively in the past in products such as insulation, cement and some floor tiles.

Fibrous tremolite asbestos on muscovite

 

Manufacturers and builders began using asbestos for its desirable physical properties. Asbestos use was widespread during the 20th century until public recognition of the health hazards, beginning in the 1970s, of asbestos dust, led to its outlawing by courts and legislatures in mainstream construction and fireproofing in most countries. Despite this, at least 100,000 people a year are thought to die from diseases related to asbestos exposure.

Asbestos is a well-known health hazard and inhalation of the fibres and long term exposure can lead to various lung conditions. Inhaled asbestos fibres aggravate lung tissues, which cause them to scar. There are three primary diseases associated with asbestos exposure:

  • Asbestosis 
  • Lung Cancer 
  • Mesothelioma 

So now that we understand what asbestos is and the health hazards it carries, removing of asbestos safely is extremely important and no short cuts should ever be taken. It is recommended that you use a licenced asbestos removalist to remove asbestos and dispose of it safely. 

If you are removing asbestos yourself you need to take precaution and follow the necessary steps to remove it safely to protect your health and the health of those around you including children. 

Some do’s and don’ts to ensure your family and the people around you are safe. 

Do’s: 

  • Plan your job so you have all the necessary equipment on hand.
  • Wear personal protective equipment (PPE) at all times. 
  • Ensure no electrical wiring or electrical products are in the work area.
  • Prepare your equipment and work area before you start
  • Only wear old clothes under the coveralls. These should be disposed of when the job is completed. 
  • Cover removal area in 200um plastic drop sheets to catch any fibres, dust and debris.
  • Wet the area that contains asbestos using a gentle mist spray of water before commencement. Detergent added to the water helps improve absorption or a mix of 1 part PVA glue to 5 parts water will help bond the material to minimise any dust. 
  • Continue wetting asbestos that is exposed – if you can see it, wet it. 
  • Spray using a spray bottle to wet smaller areas.
  • Low-pressure constant spray mist using a garden hose with a mist nozzle can be used to wet larger areas outdoors such as external walls or fences.
  • Minimise the number of people in the work area.
  • Decontaminate yourself, the work area and equipment when work is completed. 
  • Dont’s:
  • Never create dust
  • Never break asbestos sheeting
  • Never work in windy conditions
  • Never use power tools or equipment that can produce dust
  • Never use brooms or brushes except for sealing if using paint or PVA glue solution
  • Never use high-pressure water spray on any asbestos product including walls, fences and roofing 
  • Never use household vacuum cleaners. Only special H class asbestos vacuum cleaners are used by licensed removalists to collect dry asbestos dust and debris. 

An interesting fact: In 2008, South Africa banned asbestos. The ban prohibits the importation and exportation of asbestos, as well as the use and manufacturing of the mineral.

I hope I have educated you a little bit more on asbestos and the dangers of being exposed to it.

How to Build Bridges without Building Walls

Building bridges in a metaphoric term means to open up, invite people into your personal space, and create relationships with people outside of your comfort zone. This is never an easy thing to do; as we get older it gets harder to “Build Bridges” and allow people to see a more vulnerable  side of yourself. This is when we “put up walls” so we don’t appear weak to new people: – for example colleagues or clients.

When it comes to a business and the workplace, companies want employees to be able to be open and honest with each other within the Business (Building Bridges) this then creates a positive outlook when it comes to prospective and/or existing clients. With these “bridges built” within a company, it creates an atmosphere for us to be able to go out and impress clients as a collective and not individuals; therefore boosting our power within our prospective network. Empowering businesses and employees to strive for excellence. Every employee can “add a brick to the bridge”  by striving for a positive office environment, as well as when representing the company by portraying a sense of professionalism.

Walls are important when building a solid structure such as an office block or building a new mall, but “Walls” are not good in a working environment. Walls are a metaphor for anything that is creating a negative block; walls contain a build-up of negative energy.  When employees or even management of a company or businesses build walls, it can cause in office fighting and a lack of trust between management and employees.

There is going to be times when walls are going to be built, but it is important to break down those walls and build bridges.

Pope Francis quoted; “Build bridges, and tear down walls.”

World’s Funniest Engineering Fails – Bridges

World’s Funniest Engineering Fails – Bridges

When building of a bridge is conducted it’s a convoluted situation requiring knowledge and proficiency. Various key aspects come into play, such as costs, Engineering limits, and Environmental Impacts, when deciding which construction method to use and bridge type to build. These are all aspects to look at before construction takes place. There are also numerous reasons bridge Engineering could conceivably fail such as Environmental issues (floods, fires, Earthquakes); construction incidents, and most commonly design flaws.

We depend on professionals to seemingly take note of all these aspects.

In the line of history, Engineers have made many mistakes that make us just wonder? “What in the act of engineering are you doing?”

 

A few examples of the world’s funniest Bridge Engineering fails include:
“Just meet me half way…”
Copenhagen’s Kissing bridge.
Located in Denmark, The construction started in 2011 and it was ‘intended’ to open in 2013. The bridge had several errors one of which was being misaligned (Not meeting in the middle) that delayed the construction for just over 2 years. The bridge that did not end up kissing. They had one job, one job…

Another example, is right under our noses, situated in South Africa.

“ To be continued…”
The Foreshore Freeway Bridge in Cape Town also known as the “unfinished bridge”. The construction started in 1977, and due to lack of funding it was never finished. The purpose of a bridge structure is to bear a passage, #justsaying. This unfinished business has somewhat become a tourist attraction in the City of Cape Town. So there is at least one positive aspect to this failure.

As history has proven to us that not every Engineer takes note of precision – but, we surely hope that our future Engineers would take note of these mistakes and hopefully learn from them, as amusing as they may be.
