Where Construction & Technology Converge

posted in: General 0

Where Construction & Technology Converge

We live in a world where there is a technical solution for most of our problems.

You need fast communication, you no longer send a pigeon or letter, you pick up the phone or open your laptop and call, email, fax or send a message to someone. It is slowly becoming the same concept in the construction industry not only with technology but machinery as well.

Technology has reduced our life cycle as well as cost of a project drastically. Completion time, quality as well as safety have all improved through technology. Such improvements could not have come at a better time since construction projects are becoming increasingly complex and expensive putting construction teams under a great amount of pressure to reduce costs, time-lines and efficiency.

Many construction companies have begun incorporating new construction technologies into their daily activities and most of these daily activities consist of software or programmes for digital collaboration. A perfect example of this would be our very own Leads 2 Business information platform. Subscribers all over Southern Africa relay on Tender and Project information being published daily in order to attend Site meetings, meet Closing dates, obtain Bidders Lists, Site Attendance Registers and Bill of Quantities (BoQ’s).

Following Projects from Conceptual through to Completion on the L2B information platform can save a great amount of time, energy and costs.

A simple laptop or computer allows contractors as well as consultants to install many costing, design and performance programmes which allows them to use design, pre-construction or operations and management programmes, minimizing many obstacles along the way. Computer aided designing helps in flawless buildings as computer stimulation problems can be found and resolved before constructing buildings physically. Can you imagine building a whole puzzle only to find that you had one single puzzle piece place incorrectly? This would include you taking the whole puzzle apart only to reshuffle the whole puzzle to create your perfect complete picture.

With the economic challenges that are being faced, typically it is the companies that have the ability to adapt and utilize technological change that hold a huge competitive advantage over the rest of the construction companies. Technology has and will continue to become a strategic and long term asset for any construction company.

 

“Where can we find greater structural clarity than in the wooden buildings of old? Where else can we find such unity of material, construction and form? Here, the wisdom of whole generations is stored.”

Did You Know #DYK: How To Extinguish Different Kinds of Fire?

posted in: Did You Know 2

How To Extinguish Different Kinds of Fire?

Did you know that in order for a fire to exist there must be four elements present? The four elements are namely oxygen to sustain combustion heat to raise the material to the correct temperature, fuel to support combustion and a chemical reaction – (Oxygen + Heat + Fuel) = Chemical reaction. This very simple formula will determine the extinguishing agent you need to be using in order to put out your fire.

How many people just run for water when there is a fire?

Unfortunately, it is not that simple!

Let me simplify the concept of fire and how we can extinguish these fires:

 

Types of fire:

Class A – Ordinary combustion, these are flammable materials and these fuels the source e.g. Wood, cloth, paper and even your basic day to day trash.

Class B – This fire source uses flammable liquids e.g. petroleum, different kind of tars, oils and even paint.

Class C – Energized electrical equipment/components e.g. Computers, servers, motors, transformers and our daily appliances.

Class D – Combustible metals e.g. magnesium, titanium, sodium, lithium and potassium – these are mainly present in a laboratory environment.

Class K – Cooking oils and greases – We all cook meals with either vegetable or animal fats and these are the components that can start this fire.

Now that we know about and understand the different classes of fire, let’s discuss our different options for extinguishing these fires.

 

The different types of fire extinguishers:

  1. Water – The water extinguisher has a cooling effect on the burning agent causing the fire to burn more slowly.
  1. Powder – Dry powder extinguishers smother the fire and form a barrier between the fuel and the oxygen that is allowing the fire to ignite.
  1. Foam – Foam extinguishers have a cooling effect on the burning agent, creating a barrier between the flame and the fuel that is causing the reaction.
  1. Carbon dioxide – CO2 Extinguishers suffocates the fire allowing it to kill off the oxygen that is reacting with our fuel source.
  1. Wet Chemical – Wet Chemical extinguishers work by creating a layer of foam that prevents the oxygen from fuelling the fire. It creates a cooling effect and kills the fire.

 

The last thing we will be discussing to solve all your fiery situations are which fire extinguisher types to use for the different classes of fire:

Type Class A Class B Class C Class D Class K
  Combustible Materials Flammable Liquids Electrical Equipment Combustible Metals Cooking Oil & Gas
Water x x x x
Foam x x x
Dry Powder x
CO2 x x x
Wet Chemical x x x

L2B Blog: 5 Ingredients in the Constructions of a Road

5 Ingredients in the Constructions of a Road

5 ingredients in the Construction of a Road

Have you ever baked a cake and realised you forgot to add the flour or the baking powder? What tends to happen? Your cake flops or does not rise. Building a road is similar, but a lot more complex. There are so many ‘ingredients’ and important aspects that need to be considered before and during the construction of a road.

The first step to constructing a road would be planning. Your engineer/consultant would come on site and decide what type of road will be built and what materials would be used to construct the road. This will all depend on how much traffic will occupy this road. Even the simplest of roads can take up to months or possibly even years for the planning of the road. The engineer will need to evaluate many factors such as the environmental impact of the road, the availability of materials needed to construct the road, will the road be safe and, the most important factor, the cost of the road. These plans will be written into a final proposal where the consultants will need to evaluate these plans. Meetings will take place with all parties concerned and all the pros and cons will be discussed in vast detail. Without proper planning and careful consideration of all these factors, there is a chance that the foundation will collapse.

Shortly after careful planning and long and tedious meeting’s the plan will either be approved or rejected. We are going to assume that the planning was approved. The next step would be the construction of the actual road.

Ingredients used to construct a road:

 

1. The standard Foundation:

Bulldozers and graders, which are two types of machinery, will be used to flatten the ground surface. This ground layer will make up the bottom layer of our road

2. Gravel:

The gravel will be added in layers where a roller machine will be used to roll over this surface to ensure that the surface is compact and flattened

https://commons.wikimedia.org/wiki/File:Gravel_small_stones.jpg

 

3. Drainage facilities:

Drainage facilitates play a huge role in ensuring that the road is safe at all times from water backlogs. We are not able to control the weather and for this reason, we need to ensure that the road never gets saturated and water-logged. Firstly it is not safe for drivers on the road and secondly, the road will soon disintegrate and start deteriorating over time. Examples of drainage facilities would be drain and storm water sewers.

https://commons.wikimedia.org/wiki/File:Storm_drain_pipe_(crop).JPG

Once the foundation is complete and compact and has been inspected by the consultant, it is time to pave the road!

4. Asphalt / Bitumen

Asphalt uses an oil based substance called bitumen to make sand and crushed rock stick together like a glue-like substance. The asphalt is heated to +- 300 Degrees Fahrenheit (148,88 Degrees Celsius), where it

will be transported to the site where the construction team will spread the mixture evenly across the smooth gravel service. The mixture is rolled over the gravel surface where it will form a solid layer on the top.

https://commons.wikimedia.org/wiki/File:AF-asphalt-laying-machine.jpg

 

5. Concrete Slabs

The finishing touches will be the concrete slabs that are laid on the side of the roads. Workers will pour liquid concrete into a steel mould called forms. A finishing machine is used to shake these moulds to ensure the mixture is distributed evenly for an even finish. The concrete slabs are laid alongside the road where incisions in the road are made to allow the concrete to expand and contract depending on the temperature, this will ensure that the road does not crack

https://www.google.co.za/search?q=Concrete+Slabs&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi7xaKyytXTAhVCwBQKHZTXCEIQ_AUIBigB&biw=1600&bih=751&dpr=1#tbs=sur:fc&tbm=isch&q=laying+Concrete+Slabs+for+a+road&imgrc=szGP9Kx5Ii-zkM:

 

Every day we take our course of life, may it be a trip to the shop or work and take for granted these roads that we drive on. Most people think they just appeared or are set up overnight by machinery. The planning and work that goes into these roads are far more complex than most can imagine.
