L2B Blog: Sustainable construction with 3d Modelling

I was asked to write a blog on “sustainable construction with 3D modelling” WHAT?!! How do you even say that? Well lets just say my heart sank and I ran around like a chicken without a head, I had no idea as to how I was going to write this blog or even how to start as I have never written a blog in my life so this was going to be a challenge, but what is a world without challenges and growth? I had another look at the topic and looked at it in a more positive way “Well….. I tried to”.

 

Let’s start with breaking it down:
What is “sustainable construction”?
A frequently used term yet nobody really knows the true meaning. Sustainable construction is the ability to preserve our environment and makes use of cost effective resources. While doing this we need to ensure we do not compromise the ability of our future generations to meet their own needs.

 

Sustainable construction is more than often misjudged by misunderstanding. Yet the very few businesses that do understand the meaning of sustainable construction do their utmost to embrace and preserve the environment by using efficient resources and stable economic growth. This also brings into effect the use of 3D modelling with the sustainable construction which also leads to saving valuable time, money, economic impact and errors found if we did not have. This technology is known as (BIM) Building Information Modelling.
Now you can see that the 3D modelling has come in and you are now thinking… okay, now what is this? Well, let me tell you about 2D then you will understand how 3D modelling works and how far we have come in the construction industry.

So what is 2D modelling?

When construction was implemented using 2D drawings, 2D drawings were not always as reliable as they would have liked, often they would find errors and faults throughout the building and sometimes only once the structure was complete. This would then cost a lot more to fix, if they could fix it. Take the leaning tower of Pisa, imagine how this building would look if they had 3D modelling back then.

3D drawings are a 3 dimensional drawing that brings your design to life. With today’s technology with BIM and 3D drawings, sustainable construction has taken a big leap forward with regards to building, laying, environment and economic growth. 3D printing/drawing has helped in the construction and development of buildings allowing them to last longer as there are fewer faults in the construction phase. BIM is a program that gathers data and allows you to make a 3D model of your vision.

L2B Blog: 10 Simple ways to go green

posted in: General 5

Have you ever wondered about Going Green but think “well it’s too expensive“ or “too time consuming”… Well, I have done some research into this and found that it’s easier than we think, here are 10 simple ways to go green.

 

1) Recycled Polystyrene – Ever wondered what happens to all those polystyrene cups we use …? well there are actually companies that recycle these items and manufacture lightweight building blocks. These blocks have so many benefits, namely, its superior insulation and it’s lightweight so transportation is much easier and more cost effective, it’s also fireproof, water resistant as well as soundproof. This product has so many benefits I wonder why so few people know about it as it’s super cost effective too…

 

Did you Know the New Table Bay Mall is being built using 15 tons of Recycled Polystyrene? For details on this Project, see PPA 16176 and 16177

 

2) ECO friendly / Green Paints – Many people only know about the traditional paints we use and the big names like Plascon, Dulux etc however interestingly enough there are ECO friendly paints out there, they have so many benefits i.e. non toxic and odourless so very effective for use in hospitals, schools etc, you even get waterproofing paints which are ideal for ponds etc. They are fire retardant too as well as flexible, they have so many benefits it’s surprising that these paints are not as common as the other major brands.

 

3) Energy Star Products – Most of us have seen the Energy Star label on our computers. Ever wondered what the energy star label on your appliance is there for? .. well, I have just learnt that it’s for energy efficient appliances, which means that these products have been independently certified to save you energy without sacrificing the features or functionalities of the product.

 

4) Light Bulbs – Changing your light bulb to a fluorescent or LED energy saving one helps protect the environment as well

 

5) Rainwater harvesting – By collecting rain water from roof tops and gutters you can accumulate more than enough water to wash cars, water gardens and top up swimming pools and ponds. Companies like Jo-Jo have a wide variety of products to suit your needs for rainwater harvesting

 

6) Grey water usage – Did you know that on average a toilet uses approx 5 litres of water per flush, if an average household of 4 people flush the toilet only 5 times a day, you can use 100 litres of water just on flushing the toilet, however, if you were to collect shower or bath water for flushing, you would knock off a minimum of 3 000 litres off your bill every month. Next time you run the bath for the kids think again before lifting the plug and letting the water go down the drain. Collect your washing machine water in tanks or buckets and water the garden or even flush the toilet with that. There are so many creative ways to save water, you can even get fancy and get pumps to pump the grey water to where you need or you can skip the gym and carry buckets around …

 

7) Energy efficient windows – I have never really thought about this before but did you know that your windows can account for approximately 30% of your heat loss during winter and heat gain during summer. Some very clever people have made double glazed windows which is basically two pieces of glass in a window pane with a very tiny gap in-between that traps air which, assists with Insulating the window’s, so next time you have to replace a window consider going this option, it will definitely save you on the heating/cooling costs of your property.

 

8) Solar – Now by now we are all pretty much clued up / familiar with solar energy, you can either install a solar geyser of solar panels to go partially off the grid or even completely off the grid. There are so many companies out there which can assist one with solar installations and although it might be a bit costly initially, in the long run, it will definitely pay off. The only problem is when Eskom decides to do load shedding again, you might some pesky unwanted neighbours camping out at your place

 

9) Cleaning Supplies – We spend hundreds of rands every month on cleaning chemicals, now not only are they expensive but they are very harmful to the environment too. Ever thought of making your own cleaning chemicals? Here are some simple ways to do so –
– All purpose cleaner – 2 cups of water, ½ cup vinegar & 1 tsp bicarbonate soda
– Glass Cleaner – 1 cup white vinegar & 1 cup water
– Disinfectant – 1 cup water & 1 cup rubbing alcohol

If you are anything like me, you will add the rubbing alcohol or lemon juice to everything for a disinfectant. You can find plenty DIY cleaning material recipes in Pinterest.

 

10) Plastic bags – Well, now this one is probably more for the ladies as it’s regarding shopping, but the men might want to know as well as this will save you more…

Did you know that a normal plastic shopping packet can cost between 30c and 60c? What do you do with that packet afterwards, do you keep them in the car for the next shop, but they tear so easily? Why not buy shopping bags, the sturdy ones that Spar, Pick n Pay and Woolworths sell. Yes, they are more expensive ranging from R12 to R40 but they last longer and will save you money in the long run. Also, some of these shops donate a portion to various wildlife funds.

 

Thank you for taking the time to read my Blog I hope that you found it interesting.

Good luck Going Green…

L2B Blog: Consulting Work in Africa

I hope that my blog doesn’t bore you too much. I like to talk – to the point where I am consciously aware that I am bothering the people around me… and yet I continue. As a mitigating consideration, (fingers crossed) I don’t think I’m boring. The fact that I think I might have the gift of the gab is probably one of the main reasons why I shouldn’t run out of things to talk about. 😉

 

I will be discussing consultants, who are they and what do they do?

 

To be honest, the very first time I heard the word “consultants”, I immediately thought of doctors, I don’t know why… probably because I’m Afrikaans. I lie awake at night sometimes worrying that my words, phrases, and punctuation will end up in court. Why? To be sentenced, of course.

 

A consultant is a person who provides professional or expert advice in a particular field of business to either an organisation or individual. There are various different types of consultants. Consultants are professionals, typically appointed by the client to perform expert tasks on a project.

 

The members of the Consultant team that are likely to be required on most projects are:

*Architect
*Engineers
*Consultants
*Quantity surveyors

 

In this regard, I’m going to focus on Architects.

 

Giving people an exceptional experience, and turning what appears to be nothing, into a space of breathtaking beauty.

 

That is the art of being an Architect. #WeLoveOurArchitects

#SiyawathandaAmaArchitectsAseAfrica #OnsWaardeerArgitekte

 

 

What is an Architect?

 

An Architect is someone who plans, designs and reviews the construction of developments. The architect is acquainted with the tender procedures and building contracts.

 

It’s amazing how opportunities in Africa became extraordinary. With the rapid economic growth, masses migrated into the cities, (which is quite distressing) how would you plan for expansion of these cities which were built for only a limited few? Well, with the right political agency and the right construction environment you can transform an empty space into a breathtaking sight, Exciting right!! I like to think that Architects develop the world, after all they create the foundation which our shopping malls, hospitals, schools and so much more are built on.

Enough harping on about how much I love architects. If you think about it for a second, throughout Africa there is a great need for mixed use developments. It’s an important aspect and this is the reason why I feel that Architecture plays a big role just as much in Africa as everywhere else.

 

The continued population growth across Africa has resulted in increased demand for infrastructure development. This has in return driven a significant rise in the number of investors seeking opportunities. There are companies whose main goal it is to provide exceptional services from conceptual to completion in developing new structures for the prosperity of Africa.

 

A long time ago there was no such thing as big flashy buildings or proper roofing with foundations and pretty things for the eyes. It was simple, traditional architecture. You had a choice of a wooden or a mud house. On the southern coast of Benin in West Africa, for example, there is an entire city built on stilts. These range from churches to banks and even hospitals. I read something once that caught my eye: “I asked him why he wanted a metal roof, and he said, because then I would be somebody.

 

Image Source

 

If you think about it, this way architects have the power to make developments in Africa a source of income for the majority of locals who happen to be young people and are most likely unemployed. If Architects build sturdy structures they are automatically creating employment. By pushing innovation in local materials with skills and craftsmanship based on African heritage, they can actually end up with a mix of development that can benefit the population. Yes, we value our Architects in Africa. If African countries keep growing, it’ll continue to be an exciting place to work as an architect. Just remember, whatever good things we build ends up building us. #ValueOurArchitects

 

I would just like to place emphasis on the importance of proper architecture in the construction industry, after all architecture is the art and science of designing and building large structures. I would like to let you in on a terrible incident that took place in Kenya due to poor consultancy service and planning. In this case Kenya’s lab got a D on their report for this “science project”.

 

In April this year a building collapsed in Nairobi, leaving at least 12 people dead and others injured. The underlying cause and I quote “is poor construction, a problem reflected across the city and many other parts of Kenya”. In Nairobi alone only 42% of the cities buildings are considered safe for inhabitants, according to the 2015 audit by Kenya’s National Construction Authority, the Daily Nation reported and I quote again “developers are bypassing construction rules and regulations in order to meet the demand” said architecture professor Alfred Omenya in an interview after two buildings collapsed last year.

 

So… Consultancy in Africa…..yes, we need you and we don’t want any more buildings collapsing in Africa.

Finishing off, I would like to encourage you to check our website at www.l2b.co.za for amazing leads and business opportunities on consultancy. You can also sign up for a free trial to see what we are all about.

L2B Blog: Waste Water Management

posted in: General 0

According to statistics recorded from August 2008 to July 2009, South Africa has 852 wastewater management plants. The question is though how many of those plants are still fully functional and how many work efficiently and fulfill their vital process? Below I will describe what the wastewater management process is as well as discuss some of the challenges faced.

Source

What is waste water management?

Wastewater management is an extremely important process that removes all the harmful components that may cause diseases from ‘sewage’ (as most South Africans would call it) water, in order to reproduce usable water again

  • Alarming fact: Around 289,000 children under the age of five die every year from diarrhoeal diseases caused by poor water and sanitation. That’s almost 800 children per day, or one child every two minutes.

Source

Steps to Wastewater Treatment:

1. Collection

  • This is the first step whereby the municipality collects water through the collection system in place so that it all comes to and from a central point. (Drainage systems) Thereafter the wastewater is directed to the treatment plant.

 

2. Odor Control

  • This is an extremely important step due to wastewater having many substances in that cause a stench over time and if not controlled it can affect the surrounding areas. Chemicals are used to reduce the smell.

 

3. Screening

  • This is where all large objects are removed, such as nappies, sanitary towels, face wipes or earbuds as this may damage the equipment. This waste is transported to landfills once removed.

 

4. Primary Treatment

  • This is where the macrobiotic (larger particles to be broken down) solid matter is removed. Wastewater is then transferred into tanks where the ‘sludge’ then settles on the surface in order to be removed by scrappers, moved to the centre and then extracted for further treatment

 

5. Secondary Treatment

  • In this process, air is added to activated sludge (sewage containing micro-organisms) in order to further break down the particles. Air is pumped into tanks and mixed with the sludge. The oxygen consumes the remaining particles which cause the large particles to settle at the bottom of the tank. Wastewater passes through for a period of 3-6 hours

 

6. Bio-Solids Handling

  • The solid matter gets directed to digesters which are heated to room temperature and treated for a month. Methane gases are produced which form nutrient rich bio-solids, this methane can be recycled and be used as a source of energy.

 

7. Tertiary treatment

  • This stage has the ability to remove 99% of the impurities and is able to produce water at the standard of drinking but is extremely expensive and requires high skill and equipment as well as steady electrical supply, which we know is not readily available at this point.

 

8. Disinfection

  • The water needs to be treated for at least 20-25 minutes in chlorine and sodium hypo chloride to remove the last bit of disease causing organisms. This is an integral part, hereafter the water is released for use.

 

Now that we have that long process out of the way, phew! We look at the fact that our water is not up to standard.

 

In a report, the DWS stated that there are extremely high levels of sewer pollution in our water due to the fact that we have dysfunctional treatment plants. How does this happen? I mean, I feel exhausted just reading that process, but it is pointed out how important each step is! Well… the following factors come into consideration: Plants are being poorly maintained, communities are growing at a rapid rate and infrastructure falling behind so these plants are operating above their capacity causing them to be overloaded.

Source

Carte Blanche also recently did a program on the state of the treatment plants where they were following up on previous discussions they had had and most of these plants had failed because either nothing was done, or a facade was put up for a few months and then the plant returned back to normal or even worse than before.

Source

Now my question is, how does this get resolved? Number one priority, in my opinion, is for these plants to firstly have some major upgrades done on them but obviously, that’s easy to say if you take the financial aspect out of it. Where should this money come from…

There are definitively some organisations trying to make a positive change and implement strategies and projects in order to succumb these challenges so feel free to check out the links for a positive change.

L2B Blog: What does a Consulting Engineer do?

posted in: General 0

Consulting Engineers are professionals that provide independent expertise in engineering and associated fields to developers and construction firms, industries and governments.

There are various disciplines within the term Consulting Engineers. We will cover a few of the Built Industry engineering field:

Environmental Engineers are involved in air and water control pollution, public health issues, recycling and waste disposal. Environmental engineers develop regulations to prevent mishaps and conduct hazardous-waste management studies in which they evaluate the significance of the hazard, advise on its treatment and containment. The environmental engineers develop technically sound solutions with regards to improving and/or maintaining environmental quality, optimising the utilisation of resources and complying with the public policy. The engineer functions as a technical advisor in policy making and legal deliberations provide technical evaluations of systems and develop management schemes for resources. Through the work of environmental engineers; individuals and businesses understand how to coordinate interaction with the environment and protect natural resources.

Civil Engineers design the built environment and manage the natural environment. They plan, design, and construct civil works like highways, bridges, water and wastewater systems, tunnels, dams and buildings.

Structural engineering is a branch of civil engineering. A vast amount of what structural engineers do involves designing structures such as buildings, tunnels, bridges, etc. The majority of structural engineers work as consultants to architects or turnkey contractors.

Electrical Engineers design and develop electrical and electronic circuits and devices, power, systems control, signal processes and communications.

Mechanical Engineers are involved in the design, manufacture, and testing of almost every product of modern society. Mechanical Engineering applies fundamental principles of mechanics to design.

 

The Oldest Profession…

A medical doctor, an engineer, and a management consultant were arguing about what was the oldest profession in the world.

The doctor started… “Well, in the Bible, it says that God created Eve from a rib taken from Adam’s body. This must have required surgery, and so I can claim with a high degree of confidence that mine is the oldest profession in the world.”

The engineer responded, and said, “But earlier in the book of Genesis, it states that God created the order of the heavens and the earth from out of the chaos. This was the first and certainly the most impressive application of civil engineering. Therefore, dear doctor, you are wrong: mine is surely the oldest profession in the world.”

The management consultant leaned back in his chair, smiled, and then said confidently, “Ah, but who do you think created the chaos?”

L2B Blog: Give your competitors the chills: Heating and cooling tips

posted in: General 0

When it comes to Heating and Cooling systems, size matters.

It may not matter for some things, but for one’s well-being and wallet, it is critical.

Air conditioning is now almost seen as a standard piece of equipment in most homes and businesses. We don’t necessarily think about it because some of us are fortunate enough to live in a home with a cooling system and most businesses have air conditioning.

Cooling technology has advanced to improve our comfort and health.

Before air conditioning, our homes and work places were very hot in the summer. In the heat of the summer, homes and offices, even large warehouses and the like were not the comfortable, cool sanctuary they are today. To catch a cool breeze was not very easy as most (if not all) closed-up homes were too hot and uncomfortable. Windows were opened as much as possible to provide some ventilation to the building.

Air conditioning was first installed residentially in 1914. The unit was 7 feet high, 6 feet wide and 20 feet long! Obviously, the size of the system was quite costly and only could be installed where space was ample. Wealthy people with large homes were really the only ones who could access it.

Early air conditioners were loud, the efficiency was poor and were expensive to operate.

Air conditioning manufacturers have taken great strides to develop efficient cooling technology and convenience with seemingly endless equipment choices.

Air conditioning has also become more environmentally friendly as research has shown that Freon is linked to ozone depletion, currently, the R-22 refrigerant is being phased out and environmentally-friendly R401A refrigerant is the new standard.

Air conditioning systems have become much more affordable over the years, leading to their widespread use in the world all over. Today, more than 80 percent of homes and businesses in the world have an air conditioning system. The addition of the air conditioner has changed architecture, making it possible to have windowless buildings and dwellings without patios.

Keep cool and thank an HVAC Tech!

Below are some Heating and Cooling tips:
  • Keep your AC lower at night
  • Use portable units e.g. fans and heaters – costs less too and circulates the air
  • Close off vents
  • Keep your ducts in a row – make sure the areas where your ducts run through are properly insulated
  • Try 22 degrees – leave the thermostat alone – nice and steady there she goes
  • Keep your AC in the shade
  • Insulation is a cost effective barrier to heat loss and gain in your home
  • Windows, doors and skylights – if well designed can significantly improve energy efficiency and comfort
  • Seal air leaks and beef up insulation
  • Prevent heat loss – close windows and doors
  • Draft stoppers – seal gaps under doorways.
  • Heat and Cool only the rooms that are being used
  • Timers – for when and how long you need it.
  • Close doors of rooms that are not being used

Life is so much easier when we chill out! So with that in mind:

Husband: How long has the AC not been working?
Wife: 2 weeks
Husband: Why did you wait 2 weeks to have it fixed?
Wife: Your parents were here, planning to stay for the month!

Remember HVAC Tech Day 22 June.

L2B Blog: Fresh ideas about airconditioning

posted in: General 8

If you live in Durban like I do, you would know that living without air-conditioning or some sort of cooling system is absolute TORTURE!

In the extreme heat of summer, it can be quite tough to look and smell clean & fresh (TRA-LA-LA) all the time! There have been days where it felt like my makeup was literately melting off my face, not to mention the regular ‘sniff’ checks I needed to perform, not wanting to scare any potential subscribers away by looking like ‘The Crow!’

First, let’s go back in time:
One of the first A/C systems was invented by Willis Carrier in 1902 and was called the Ice Machine. It was developed to bring down the temperature and remove the humidity from the air.

 

 

Current time:
It’s been predicted by the Netherlands Environmental Agency, that by 2060 the amount of energy used worldwide in COOLING will overtake the energy used for HEATING.
As it stands, the United States uses as much energy to keep things COOL as the whole of the African Continent uses on EVERYTHING. Countries like India and China are fast catching up and by mid-century we will use more energy for cooling than heating!

 

 

But it’s not all “DOOM and GLOOM”

Since then, technology in A/C has improved and evolved dramatically. In 1992 conservation standards for manufacturers of central air conditioners and the heat pump were issued and in 2006 the energy SAVING from 2006 to 2035 is equivalent to the annual greenhouse gas emissions of about 72 million cars.
It has improved so much that the A/C today uses about 50% less energy that they did in 1990.

 

One of the ways to save not only on your electricity bill but also our planet, is a solution called: Ducted Reverse Cycle Air-Conditioning. It’s an Energy Efficient Solution for your home.
And because I had no clue what ” Ducted Reverse Cycle Air Conditioning” was before I did my research for this Blog, I think its a good idea to explain with a picture. 🙂

 

 

Ducted Reverse Cycle Air-Conditioning works through a fan that draws the hot air from your house and transfers it over a cold liquid called refrigerant. The air is then cooled and flows back throughout your house. The hot air that flows from the compressor evaporates. The compressor creates high-pressure gas and high-temperature gas. This gas is then pumped through to a heat exchanger that is located outside. Because the heat is able to escape, the refrigerant can then cool.

Benefits of this system:
* You have the option to either heat or cool a room
* It allows you to control the temperature from a control panel
* Sensors in different rooms ensure the correct temperature is maintained
* Comes with a zoning function option, allowing you a selection of different air flow and temperatures for different rooms

 

Very impressive: The Fourleaf Estate residential development in Port Elizabeth is the VERY FIRST residential project in AFRICA to meet the Edge resource-efficiency standard and to receive an “Edge final certification” from Green Building Council South Africa (GBCSA).
Click here to view details of this Project on L2B

 

If you are going to “FLIP that SWITCH”, herewith are some pointers on SAVING ENERGY:

Generally, the best temperature to set your A/C unit is around 24-25°C.
You can save considerably on the amount of energy used for each 1°c of heating or cooling that you do without. Should it be 35°C outside, by setting the temperature around 25, instead of 22, you could save a significant amount of energy.

 

And for those of us that DON’T have the LUXURY of air-conditioning, herewith some suggestions to keep cool:

* Shade your windows in summer with curtains, shutters and blinds that can reduce heat absorption by up to 80%.

* Create more shade outside of your house with awnings and trees.

* Hack a fan.

* Set your ceiling fans to rotate counter-clockwise. Some ceiling fans even come with a remote control.

* Let the night air in by keeping windows open.

* Focus on your body temperature by hydrating with cold drinks.

* Install UV film on your windows to reduce heat and glare.

* And lastly, instead of cooking indoors, in true South African style, “NOU GAAN ONS BRAAI!

 

So, regardless if you want to CRANK UP the temperature during the cold winter months or DOWN in summer, consider that WE ONLY HAVE:

L2B Blog: Epic Air Conditioning Fails

As we all know the winter season can be a chilly “bordering on freezing” climate that has its ups and downs, the last thing we need to be worrying about is our air conditioning unit failing on us.

Being office bound, we need to ensure ourselves as well as our colleagues are comfortable in order to create a smooth working environment. So I have emphasized on the most common air conditioning problems that we could experience and a solution to the problem.

   

PROBLEMS / SOLUTIONS:

  • Having an air-conditioning unit on, whether it be at your office or at home, you should ensure that all doors and windows are closed in order for the air-conditioning unit to operate to its full potential.
  • Lack of maintenance on your air conditioning unit can result in permanent damage to your unit. You should ensure that you hire the correct air-conditioning technicians to service and maintain these units. Correct maintenance can ensure less chance of a breakdown. Ensure that you get your air-conditioning units serviced on a regular basis to ensure that dirt is removed off the compressor so that your unit does not fail prematurely.
  • Poor installation of your air-conditioning unit can result in the lack of air-flow and leaking ducts (Piping that allows for distribution of airflow). Having a lack of air flow will be established immediately as you will not experience the satisfaction of having your air-conditioning unit switched on. Always ensure that you hire an accredited company that will be installing your units as poor installation can give you endless problems which may result in you having to replace your air-conditioning unit.
  • If you are experiencing a leaking air-conditioning unit, this could be from the lack of or too much refrigerant within your unit. Please take note that if you conclude that the refrigerant is the problem, do not attempt to just fill it up or release some refrigerant as the manufacturer of the air-conditioning unit specifies exactly the required amount of refrigerant that should be in the unit in order for it to operate correctly.
  • Finally, if you have a room or office air-conditioning unit and it is humid outside, on a regular basis check that your condensate drain is draining correctly and there are no objects that are blocking the drainage, this can also affect the running of your system.
   

 

TIPS:

  • Ensure you hire the correct team in order to keep your air-conditioning units in great condition.
  • Do not be left stranded in the cold or the heat due to air-conditioning units that have failed!!

L2B Blog: Visions of the future from the architectural past

Visions of the future from the architectural past

When you look at a building, what do you see? I see bricks, some windows, a door or two, oh, and we can’t forget the roof. I am sure that is pretty much what everyone else sees. But when I was given the task of writing this blog, I couldn’t find anything on visions of the future from Architectures past besides the thoughts and visions of what the future might look like with flying cars and buildings in the air floating around (Ok, maybe not to that extent, but you get the idea). With a pounding headache and the confusion lingering, I was forced to take a deeper look into what was handed to me.

A light bulb appeared and low and behold, bam! The idea popped into my mind. I started to think a little out of the box. As the searching started I was amazed at what I discovered, who knew that there is more to a building than just bricks, windows, doors and a roof. Confused? Let me shed some light…

When you look at a building there is more than what the eye can see. There is a past, a story to be told. If I had to write about each and every building, we might be dealing with the longest blog known. Instead I have isolated 3 buildings to tell their story…

 

1. The Dresden Fraunkirche ( Church of the Lady)

The Dresden Fraunkirche is a Lutheran church in Dresden, capital state of Saxony, Germany, first built in the 11th century in a Romanesque style. The first Frauenkirche was torn down in 1727 and replaced by a new and larger church. The church’s most distinctive feature was its unconventional 96m high dome, called ‘die Steinerne Glocke’ or “Stone Bell”

 

 

 

 

 

 

 

 

 

 

(Frauenkirche, between 1860 and 1890)

 

The destruction of the Frauenkirche took place on 13 February 1945, when Anglo-American allied forces began the bombing of Dresden. The church withstood these attacks for two days and nights and held long enough for the evacuation of 300 people who had sought shelter in the church. The dome finally collapsed on 15 February. The pillars exploded and the outer walls shattered and nearly 6 000 tons of stone plunged to earth.

 

During the last months of World War II, residents expressed the desire to rebuild the church, however reconstruction came to a halt due to political circumstances in East Germany. Due to the continuing decay of the ruins, Dresden leaders decided in 1985 to rebuild the Church of Our Lady. The project gathered momentum as hundreds of architects, art historians and engineers sorted through the thousands of stones, identifying and labelling each for reuse in the new structure.

 

Reconstruction proceeded in February 1992 and a rubble-sorting ceremony started the event in January 1993 under the direction of architect and engineer Eberhard Burger. The foundation stone was laid in 1995 and stabilised in 1995. In 1996 the crypt was completed followed by the inner cupola in 2000. The exterior was completed by 2004 and the exterior painted in 2005. The intensive efforts to rebuild this landmark were completed in 2005, one year earlier as planned and in time for the 800-year anniversary in 2006.

2. The Reichstag Building

The Reichstag building is a historic edifice in Berlin, Germany which was constructed in 1871 to house the Imperial Diet of the General Empire.

(Reichstag Building, August 1932)

 

The building was opened in 1894 and housed the Diet until 1933, when it was severely damaged after it was set on fire. The building fell into disuse after the World War II.

(Reichstag, postwar. June 1945)

 

The ruined building was made safe against the elements and partially refurbished in the 1960s. Only after the German reunification on 3 October 1990, did the Reichstag undergo reconstruction led by Architect Norman Foster

During reconstruction, the building was almost completely stripped, taking out everything except the outer walls. Respect to the historic aspects was one of the conditions stipulated to the architects so that traces of historical events were to be retained in visible state.

Reconstruction was completed in 1999 and is the second most visited attraction in Germany. The building houses a huge glass dome that was erected on the roof as a gesture to the original 1894 cupola.

3. Last but not least, the demise of the next buildings, shattered America and brought the world to a standstill… the World Trade Centre (The Twin Towers)

At the time of their completion the Twin Towers were the tallest buildings in the world. On 20 September 1962, the Port Authority announced the selection of Minoru Yamasaki as lead architect and Emery Roth & Sons as associate architects. The original plan was for the towers to only be 80 stories tall, however, to meet the requirements of the Port Authority to have 10 000 000 square feet of office space, towers were eventually 110 stories tall. Demolition work began on 21 March 1966 to clear thirteen square blocks of low rise buildings. Groundbreaking took place on 5 August 1966. On 4 April 1973 the Twin Towers opened.

 

About 50 000 people worked in the towers with approximately 200 000 additional visitors passing through on a typical weekday. On 11 September 2001, the world came to a standstill when terrorists hijacked American Airlines and deliberately crashed into both the towers. It was estimated that approximately 17 400 occupants were in the towers at the time of the attacks and 2 977 people died as a result.

 

During the following years, plans were created for the reconstruction of the World Trade Centre which is now known as the World Trade Centre Memorial and Museum. They commemorate all the victims that were killed on 11 September 2011, including the names of 6 people who were killed in the World Trade Centre bombings in 1993. Construction began in August 2006 and despite many delays, the opening of the memorial took place on 12 September 2011, one day after the 10th anniversary of the terrorist attacks. The names of the victims are inscribed on 76 bronze plates attached to the walls of the memorial pools. Below is the transcript of ‘The Memorial Mission’:

 

‘The Memorial Mission’

‘Remember and honour the thousands of innocent men, women, and children murdered by terrorists in the horrific attacks of February 26, 1993 and September 11, 2001.

Respect this place made sacred through tragic loss.

Recognise the endurance of those who survived, the courage of those who risked their lives to save others, and the compassion of all who supported us in our darkest hours.

May the lives remembered, the deeds recognised, and the spirit reawakened be eternal beacons, which reaffirm respect for life, strengthen our resolve to preserve freedom, and inspire an end to hatred, ignorance and intolerance.’

 

 

With a new outlook on buildings, always remember that just like each and every one of us, we all have a story to tell. A past, a present and a future.

L2B Blog: Exploring New Ideas in the Role of the Project Manager

Exploring New Ideas in the Role of the Project Manager

If you are involved in the construction industry you have most likely come into contact with a Project Manager (hereafter referred to as a PM) or heard of one mentioned in the process of developments and particularly larger developments.

Certainly in Leads 2 Business’ Projects Department PM’s are one of the most common professionals we deal with. The reason for this, is their role within construction projects.

So, what does a PM actually do? It would seem rather obvious right, they manage the project? But nothing is ever as simple as it seems. PM’s actually do a whole host of duties.

Some of which include: planning, organising, controlling, communicating, executing, reports, programs, advice, analysis, resource control, health and safety, budgets, administration and handover.

All of these duties are done ensure that the project runs successfully thus lowering the risks while meeting all of the objectives timeously to ensure completion which effects the profitability of the project.

So, when do new ideas come into the picture? What new ideas would PM’s have to explore in todays construction industry?

To be honest, I was at a loss when pondering this question, after all I’m not a PM and it’s not a role one easily assumes to answer. So I emailed a few PM’s to get some feedback on ideas that they might want to put out there… but still no luck, probably snowed under with work given our economic environment. I scoured the Internet and there didn’t seem to be any publications or news out there for new ideas when it comes to PM’s until I happened on some LinkedIn Posts. Phew!

This may not be a new idea but how about technology, either using existing tech and / or molding it to PM’s requirements, partnering with IT and creating PM specific tech or even sharing your tech tricks with other PM’s? For example: Ahmed H. Emam, PMP writes “Detect and Fix Dangling Activities in Time Schedule using Excel Macro.” https://www.linkedin.com/pulse/detect-fix-dangling-activities-time-schedule-using-excel-pmp

Using tech could make PM’s jobs easier but some seem to think that PM’s might be replaced in the future by Tech/Bots. As Oliver Yarbrough, M.S., PMP illustrates in “Can a Robot Do Your Job? Here’s “How Project Managers Can Survive a Takeover.” https://www.linkedin.com/pulse/can-robot-do-your-job-heres-how-project-managers-oliver

There are some things that tech, no matter how advanced it gets, cannot replace. Oliver suggests to focus on the following skills in order to stand out: “Leadership, Diplomacy, Negotiating, Public Speaking, Emotional Intelligence, Communication (verbal and nonverbal)” and instead of fighting tech, work with it to enhance your service delivery.

Another thought also came to mind: what is one of the key aspects that I think of when I think of a PM? It would have to be communication. So, what new idea would make communication more effective? What about a platform where all the schedules, notes, admin, planning and analysis can be seen by all the professionals involved in a specific project? Where each person can make notes or get alerts thus avoiding confusion, emails back and forth, potential loss of material, and saving time, something like Google Sheets for PM’s? Does this already exist? It’s possible… calling all PM’s out there, let us know! Perhaps I need to patent this idea.

After all, we all know that communication is key whether you are a PM or not. Another useful tool to facilitate communication and interaction between professionals and all other contacts which fall within the scope of projects is to use L2B (Leads 2 Business). If you are looking to get involved in the different aspects of construction, information is our business. We encourage communication, new ideas and growth in order to build and establish business.
