Construction Pollution

 

Our planet has been fighting a non-stop battle against pollution. On our average day today, we do not take note of the damage we cause to our planet. This is a very sensitive topic to most people. Typically we hate to face the reality however at some point it is inevitable to avoid.

Construction pollution involves so many aspects in this topic from Air, water, soil, and/or Noise pollution. This is caused by the materials used, such as harmful chemicals used during the construction. Fossil fuels being one of them produces greenhouse gases that harm the environment.

The most common types of pollution found on Construction sites are dust and diesel emissions. Dust pollution being a very common Construction Site pollution, It may contain Microscopic solids or liquid droplets, they are minute enough to seep into the lungs and cause health issues such as wheezing, Bronchial infections, dermatitis, Asthma attacks and more. It can also contain chemical particles that can cause Long-term Health issues.

Out of 195 Counties, South Africa is standing at 37 on the list of the most polluted, with stats standing at 21.56 Average PM2,5 (Fine particulate matter 2.5) refers to tiny particles or droplets in the air that are two and one-half microns or less in width. It is caused by Car, truck, bus and off-road vehicle exhausts and from operations that involve the burning of fossil fuels such as wood, heating oil or coal. Consideration to our communities around our construction sites plays a role in reasoning to reduce our pollution on site.

Let’s look at ways to reduce Construction Pollution

Time: Consider time management on site. Decrease the amount of time spent on site. Modular construction can decrease time and speed up the process. “Modular construction – is a process where pieces and structures are built off-site in manufacturing plants before being transported to the job site “

Vehicles: Construction sites require the use of machinery. It is a tough one. The use of economic fuel-efficient vehicles “Tier 4 equipment”. The use of this equipment reduces hydrocarbon emissions. Reducing idiling time will benefit in more ways than one. Saving on fuel expenses and reducing Air pollution.

Clean-Up: No one enjoys cleaning up after a long day’s work. So create a cleanup policy, have bins laid out across your construction site, so your workers can have a clean Working environment with no arb wrapper in the midst of your equipment.

Transportation & the Construction Industry

posted in: Construction Chat 0

Planning and transportation of materials, tools, and equipment is an important aspect of completing any construction job on time. Construction projects have many moving parts and managing all of these different elements is crucial to the success of any project, so you have to have to make sure you have a logistics plan in place in order for the project to run as smoothly as it possibly can and within the budget of course. We do not often think or realize how important this aspect of the project is.

Depending on where the site is will ultimately decide how the materials will be transported as well as what is being transported. The most common mode of transportation are trucks and flatbed trucks and trailers.

When the site is ready and all the materials and equipment have arrived, the transportation of construction material on site begins.

Examples of construction equipment on a site:

1. Boom Lift – a type of aerial platform used to get workers off the ground to work on an elevated project.
2. Scissor Lift – Similar to a boom lift, scissor lifts are aerial work platforms used to elevate workers.
3. Forklift – If materials need to be transported a short distance, forklift equipment can be used.
4. Telehandler – used for jobs where a forklift is inadequate. It’s more heavy-duty than a forklift and can access much higher areas as well.
5. Bulldozer – is used to push, carry and condense any sort of loose material on site.

6. Skid Steer Loader – a skid loader can host different equipment and is also small enough to maneuver into tight areas of a site.
7. Excavator – An excavator is a heavy piece of machinery used to dig and crush material on a site.
8. Off-Highway Truck – The off-highway truck is specifically made for rugged environments. This heavy-duty dump truck has massive wheels with deep treads, allowing it to venture off-road and support construction and mining sites. It’s primarily used to transport materials like rocks or dirt from one site to another. Some models use multi-axle dump buckets to support even heavier loads.
9. Carry Deck Crane – A carry deck crane is a small, mobile crane system.
10. Articulated Hauler – As with an articulated truck, an articulated hauler has a pivot joint in its build, giving it increased mobility. Because of this joint, it can carry massive loads around tight turns, making it ideal for most structural builds. This dump truck has a control hub where the driver sits and a material pail where loads go to be transported. Almost all articulated haulers are four-wheel drive, giving them access to most sites regardless of condition.

Construction Highlights from 2020

posted in: Did You Know 0

Where do I even start? 2020 was a year like no other, caused by a global pandemic that claimed many lives, spiked retrenchment, closure of businesses, projects paused, increased food prices, and the list goes on. But today we focus on Construction Highlights from 2020. With Covid-19 construction had to adapt to new trends and technology. This coming with both disadvantages as well as advantages, communication between tenderers and clients became easier, but connectivity was sometimes an issue, systems required constant updates. IT was and continues to be the biggest contributor to communication during these times.

The construction industry was knocked with the Level 5 lockdown as all work came to a standstill for roughly 3 months, impacting on completion time, as well as other projects that were in the pipeline.

Commercial construction stats are expected to fall by 16% in 2020, with retail stats projected to be down by 33% and hotel/motel stats by 31%. Apart from the bad, there was also a good side to construction in 2020, please see projects below.

1. Calgro M3 breaks ground on student housing projects in South Africa (Linked to PPA 25970 which is Underway)

To be located within the Belhar CBD development, a mixed-use residential project, the accommodation will be built in three parcels of land located next to one another.

The 44 000m² site will border the southern boundary of the University of the Western Cape campus and is situated close to the Unibell train station and the Cape Peninsula University of Technology.

Comprising of six buildings with nearly 2,720 beds, the accommodation will have different types of sleeping quarters for students including single and double rooms and double room apartments.

Additionally, there will be suitable accommodation and ablution facilities designed specifically for disabled students.

The accommodation is expected to have several communal facilities within the residences such as bathrooms, lounges, study and dining areas, kitchens, laundries, and tuckshops, along with gym areas and residence manager apartments.

2. World Bank approves $131m financing to upgrade roads in Uganda (Linked to DTA 818876 which closed on 03 July 2020)

The Uganda Roads and Bridges in the Refugee Hosting Districts Project will involve upgrading 105km Koboko-Yumbe-Moyo road, and upgrade road infrastructure in areas hosting refugees in the country’s West Nile sub-region.

Additionally, the bank is financing the rehabilitation of the 340km Tororo-Mbale-Soroti-Lira-Kamdini road under the Uganda North Eastern Road-corridor Asset Management Project as well as the construction of the 100km of the Kyenjonjo-Kabwoya road under the Albertine Region Sustainable Development Project.

3. Maire Tecnimont wins $400m contract for two oil and gas projects in Algeria (The contract, worth $400m, was secured by Maire Tecnimont’s subsidiary Tecnimont)

The project will be implemented in the BirSeba and Mouiat Outlad Messaoud oil fields, located in the Touggourt area, about 130km northeast of Hassi Messaoud.

The scope of the contract includes full engineering, procurement, and construction activities such as the expansion of the existing oil central processing facility, by installing a new oil separation train to double the total capacity up to 40,000 barrels of oil per day.

It also includes installing two additional remote gathering stations and over 400km of pipelines connecting the new oil production wells, along with implementing gas lift and water injection facilities.

Construction Technology

Posted by Brett Long

If it’s not broken don’t fix it, right? Despite technological progress, it’s not uncommon for construction companies to still rely on spreadsheets, manual data entry, and paperwork. Low IT budgets and lack of time for training have contributed to a hesitancy around adopting new methods and technology.

Emerging construction technology isn’t just a fad or a fun new toy. There are real, practical applications and benefits to modernizing your current processes. And if your construction company wants to remain competitive and not be left behind, you’ll need to find ways to integrate new approaches into your strategy and workflows.

These cutting-edge technologies are drastically changing how the industry operates and how future projects will be completed.

Types of Construction Technology Impacting the Industry:

  • Mobile Technology
  • Drones
  • Building Information Monitoring (BIM)
  • Virtual Reality and Wearables
  • 3D Printing
  • Artificial Intelligence

1. Mobile Technology

Mobile technology isn’t just for games anymore. Apps are becoming more of the norm in construction and for good reason. The increased portability of tablets and smartphones allows for greater communication and the ability to work from anywhere. Integrating this type of technology into your current processes can be much simpler and require a smaller upfront investment while still providing major benefits and boosting productivity in your day-to-day operations. So if you want to start implementing technology, this is a good place to start.

Mobile technology can help to save time and keep your project moving forward faster by providing real-time updates and making information available between the job site and the office. You can easily access the latest revisions to plans or report a problem to the project manager off-site.

2. Drones

Drones are the most widely used emerging construction technology. They can conduct site surveys more quickly and accurately than a crew on the ground and are cheaper than aerial imaging. Their high-resolution cameras and the data collected can create interactive 3D or topographical maps and models and take volume measurements.

Another benefit of using drones is the ability to inspect hard-to-reach places such as bridges or around tall buildings, and to do it safely. You can also use them to monitor progress on a job site and see how people are working.

3. Building Information Modeling (BIM)

BIM is similar to CAD (computer-aided design), but not exactly the same. It is software for 3D design to digitally model what will be built. But its capabilities don’t stop there: “It doesn’t just create a visually appealing 3D model of your building—it creates numerous layers of metadata and renders them within a collaborative workflow,” writes Engineering.com. It captures things in a way that paper just can’t.

32.7% of builders are currently using BIM/CAD software, JBKnowledge reports in their 2016 survey. The use of BIM has even been mandated in the UK for government construction projects.

The use of BIM provides space for better collaboration because each person and expertise area can add their piece to the same model, instead of breaking out onto multiple versions of a 2D paper drawing. This way, the model evolves immediately as people contribute, streamlining the process and increasing efficiency. BIM also helps with problem-solving in the design and planning stages of a project, by automating clash detection and providing a more complete picture of the project.

4. Virtual Reality and Wearables

Virtual reality technology is often used in conjunction with BIM to help better understand complex projects. Think of the potential: you create a building design with BIM and can then use VR to actually walk around it. Pretty cool, right? This will give your team, or the client an even more realistic idea of what the project will look like once completed. Having a more complete grasp on the project before it begins allows you to avoid big changes and expensive change orders mid-way through.

Wearables are a construction technology that will have an impact on job site safety and risk management. The Daqri smart glasses, though still in the early stages, are one example. The glasses have an augmented reality display, wide-angle camera, depth sensor, and other features that allow workers to collect and see data based on their environment. The glasses give workers the information and instructions they need to complete a task right on the display, getting the job done faster and with less room for error.

5. 3D Printing

3D printing as a construction technology has the potential to change material sourcing. For prefabrication, materials for a project can be printed and then transported to the job site, ready for use immediately. This can allow you to get materials faster and streamline the process by removing extra steps in the middle.

According to the U.K. Green Building Council, around 15% of materials delivered to construction sites end up in landfills, and the American Institute of Architects believes that building-related waste makes up between 25% to 40% of America’s solid-waste stream, reports Fortune. With 3D printing it will even be possible to print materials right on site, reducing waste and further saving on transportation and storage costs.

One of the current challenges with the adoption of this technology is limitations with mass production. Although some 3D printers can produce on a larger scale, they are expensive.

6. Artificial Intelligence

The construction industry is already seeing the implementation of artificial intelligence on the job site with the use of robotics for tasks like bricklaying and autonomous equipment that can operate and complete tasks without the need for human interaction.

AI can benefit construction projects through increased safety, improving workflows, and getting jobs done faster and better. “AI can replicate the judgments, decisions, and actions of humans without getting fatigued,” said Dan Kara of ABI Research. It can also identify when information or pieces are missing and ask questions, and use the data it collects.

Tunnel Boring Machines

Tunnel Boring Machines (TBM)

A tunnel boring machine (TBM), also known as a “mole”, is a very large machine designed to excavate and drill with a circular cross-section, through a variety of soils and rock to create a tunnel.
Tunnel boring machines are used as an alternative to drilling and blasting methods in rock and conventional “hand mining” in soil. TBMs have the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel and makes them suitable to use in heavily urbanized areas. The major disadvantage is the upfront cost. TBMs are expensive to construct and can be difficult to transport, due to their very large size.
The first tunnelling machine was designed by an Engineer, Marc Brunel in the 19th century. It was used to help build the Thames tunnel in 1843 – the first tunnel under a river. Brunel’s invention was basically just an iron framework with spaces for workmen to stand-in. Tunnellers dug out the earth in front of them with pickaxes and shovels.
According to global tunnelling tradition, a TBM cannot start work until it is given a name. This tradition also sees most TBMs being named after women. Why are they given women’s names? Apparently, it’s a tradition dating back to the 1500s when miners and anyone working underground with explosives prayed to Saint Barbara to protect them from the dangers underground.
Phyllis, Ada, Elizabeth, Victoria, Jessica, Ellie, Sophia and Mary were the names of the eight tunnel boring machines used in London’s mega Cross-rail Project. Big Bertha is the infamous TBM stuck underneath Seattle and Alice tunnelled Vancouver’s new Evergreen Line.
Here in South Africa, the R300 million TMB used to construct the 3-kilometre tunnel stretching from Rosebank Station to Park Station as part of the Gautrain project in Gauteng was named ‘Imbokodo’, or ‘hard rock’. The name, ‘Imbokodo’, flows from the women’s protest march to the Union Buildings on August 9, 1956. This march saw the birth of the phrase ‘wathinta abafazi, wathinta imbokodo’ or, ‘if you strike a woman, you strike a rock’. Project officials chose the name because they believed the TBM would do her work with the “agility and effect of a super kung fu master, yet with a feminine touch of tenderness and softness as she tunnels her way through soft ground and hard rock”.

The world’s largest hard rock TBM is known as Martina, (she has an excavation diameter of 15.62m, a total length of 130m and a total weight of 4,500 tons. It was built by Herrenknecht AG, and is owned and operated an Italian construction company, Toto S.p.A. Costruzioni Generali (Toto Group) and was used for the tunnelling of the Sparvo gallery of the Italian Motorway Pass A1 near Florence in Italy.
Tunnelling machines have had an economic, environmental and cultural effect around the world. Like bridges, tunnels connecting communities, and sometimes even entire nations!
In the UK for example, modern TBMs have helped boost the economy. London Underground’s Jubilee line tunnel has brought redevelopment all along the new line.
TBMs can also be used to improve the environment. The machines that dug the Lee and Thames Tideway tunnels helped improve sewage treatment for large areas of London.
Today’s modern tunnelling machines look very different from Marc Brunel’s miner’s cage, but their function is very similar. The TBMs dig out earth which is carried back behind it – usually on a conveyor belt. The TBM moves forward and continues to dig.

Showing a TBM in action, underground

“Like giant underground factories on rails, they’re the equivalent of 14 London buses end-to-end and a staggering 143 buses in weight”
