Have you ever thought about why roads, bridges, or buildings exist in their given location? The role of planning and producing these structures rests solely on civil engineers. For this profession, education and training are only a section of the experience needed to be successful. Current events in civil engineering point us towards why this profession is so critical. Studying news in this field can help increase the understanding the public has about the job.
Civil Engineering is a discipline that focuses on the design, production, and maintenance of public works. These could include roads, bridges, tunnels, dams, public buildings, and many other structures. Overall, the role requires technical knowledge of construction and engineering as well as public works regulations. The purpose is one of the most vital positions in city planning and community organizing.
Recently, there have been some notable stories concerning advancements in civil engineering and other accomplishments by prominent civil engineers. However, these stories often go unnoticed in the mainstream media. With such crucial work going unrecognized, there is a huge gap in public knowledge of this profession. Unless you are an engineer, you likely don’t understand why buildings and structures go where they do. Let’s explore a few current events in civil engineering.
Current Events in Civil Engineering: Workforce Tensions
The people holding the position of a civil engineer is growingly diverse. At one time, men dominated the field of civil engineering. Now, women and people of color are a growing demographic in the industry. Because of this, some discrepancies are evolving. Some severe concerns are coming from industry professionals regarding wages. For the most part, civil engineers are doing the same job when on a project. Despite this, a recent study finds that women make 24% less than their male counterparts. No matter the level, men, on average, make more than women in civil engineering. It’s startling, especially as more women and minority groups are growing in the field.
A wage gap is nothing new, especially when it comes to genders. Women make 8% less than men on average in the United States. The difficulty, in this case, is the growing need for civil engineers. With so many public works projects sprouting up, the demand is there. The question becomes whether or not this near 25% wage gap deters future engineers from studying the field. It’s not unheard of to see students stopped from specific areas based on prejudices. As more and more roads, bridges, and infrastructure gets touched up in the U.S., the field is only going to grow.
More Work Requires More Workers
Nearly every state is looking to make some sort of infrastructure plan right now. At a federal level, Congress is also working on a project to rebuild decrepit bridges, roads, and buildings. As taxes are sure to come, the money will be there for those looking to get into civil engineering. The question will become who takes those jobs? Men will likely continue to serves as the majority demographic in the field. As women gain equal opportunity and consideration; however, wage gaps and workforce tensions might play a role in that. The key moving forward is keeping up with the needs of the market, which means some changes are likely to come.
The options are easy to differentiate. Either worker feels fulfilled, or they look for other jobs. The process of finding a job is not easy, even with relatively low unemployment. Nevertheless, potential engineering students considering civil positions are going to second guess their future if they might not make equal pay to equal work. Moving forward, it cannot go ignored. Rebuilding everything from tunnels to entire public buildings takes the right amount of labor. That labor will disappear if not given the pay deserved.
Current Events in Civil Engineering: Self-Healing Concrete
Concrete is a core component in the civil engineering field. However, the presence of a relatively low tensile strength means that periodic maintenance is inevitable. Over time, normal wear and exposure to the elements see the development of unsightly cracks, necessitating repairs, and in more severe cases, the need to tear down and rebuild the structure. However, these repairs can be costly. For instance, the periodic maintenance of bridges, tunnels, and infrastructure costs around 7 billion dollars annually in the European Union Alone.
The longevity of concrete is not guaranteed, and repairs are a costly necessity. Once concrete cracks, the reinforcement is exposed to corrosion as well, leading to a damaged frame.
The discovery of self-healing concrete ensures a prolonged lifespan and, subsequently, a lower cost of maintenance. The durability and sustainability are core qualities in construction.
- The employment of SAP (Superabsorbent Polymers), is also known as hydrogels. This component can absorb 500 times its weight, and this is without dissolution or loss of shape. It absorbed fluid results in swelling, which then dissipates to the surrounding matrix, closing the cracks.
- The use of CaCO3(Calcium Carbonate) helps in precipitating micro-organisms. The organisms are part of the concrete matrix, and subsequently, accelerate Calcium Carbonate when a crack occurs. This emitted compound results in the crack filling.
- Use of encapsulated polymers. These polymers, preferably elastic, break, flow into the crack, and fill it. The encapsulation material is typically composed of ceramic tubes or glass.
The first idea is to make use of Calcium Carbonate and periodic precipitation to seal cracks when the cement gets wet. Bacteria use forms a core component of the development of this special cement, with microbes such as Bacillus Subtilis and Bacillus Pasteurii playing a critical role in the active ingredients. The products of hydration form a lasting solution to the cracking challenge. The advancement of civil engineering is reliant on the consistent development of better building material.
A chief motivator for the invention of self-healing cement is the incredible financial impact, with a vast amount of savings on maintenance. The initial construction costs will rise a bit, but the structures will stand the test of time, raising the likelihood of more old structures. The reward is the comparative ROI (Return on Investment), making self-healing cement a milestone discovery.

Current Events in Civil Engineering: The Creation of Aerogels from Waste Plastic Bottles
Plastic bottle waste has proven to be a real challenge in the modern world. Even though bottles still cause significant problems, plastic containers are the most recycled plastic in the world. A team from the NUS (National University of Singapore) has succeeded in developing a methodology for converting this waste plastic into useful aerogels.
The team from NUS worked on making this discovery between 2016 and 2018. This ability to give the gels varying surface treatments enables the creation of a range of products with different applications.
Some of the defining qualities of aerogel are:
- Easy handling
- Data shows that recycling conventional plastics results in a cleaner environment. The annual volume of plastic waste expects to top a trillion tons by 2021. This waste ends up in oceans and ultimately leads to a polluted environment. Despite this, recycling ensures a cleaner, healthier environment.
- The incorporation of varied methyl groups gives aerogels the ability to absorb an impressive amount of oil swiftly. Experiments have proven these unique aerogels to be seven times more efficient than commercial sorbents.
- The insulation properties of PET aerogels makes them suitable for fire safety purposes. While firefighters have to contend with heavy coats and breathing equipment, they could use something better. Thankfully, lighter jackets lined with aerogel are more luminous and safer. This quality allows the production of affordable heat-resistant attire. A layer of fire retardant components makes it withstand temperatures in the region of up to 620 degrees.
- The production of carbon dioxide absorbing masks is significant. PET aerogel made with an amine coat quickly absorbs carbon dioxide. The absorption levels can equate to that utilized in the production of gas masks. These carbon dioxide-absorbing masks can prove priceless when evacuating high-rise buildings in the event of a fire.
Thus, the conversion of universal PET plastic waste to aerogel multiplies its uses and helps create a better environment. An impressive array of aerogel uses means that plastic recycles into more plastic. Over time, more applications will necessitate a larger scale of recycling, changing waste into a wide variety of useful products. Here’s a link for more information.

Current Events in Civil Engineering: GPS Integration into the Construction Process
Site management can be a tedious exercise, especially for massive projects run by a large number of employees. Many activities take place concurrently at any given site, and it can be utterly impossible for one or two individuals to provide sufficient oversight. Due to the need for proper monitoring, GPS technology has taken root on worksites, with tracking mechanisms put in place for both employees and equipment, manual or automated. With GPS technology, it becomes easier to monitor the movement of personnel.
- The protection of site equipment and vehicles from theft is crucial. Over time, theft of site equipment has been a constant concern. Without proper surveillance, expensive equipment has disappeared from construction sites, even with security cameras. So, GPS trackers aren’t dependent on visual monitoring and offer more security.
- Examination of employee driving preferences and for safety and risk assessment. Even at small companies, fleet management is a critical facet of running the business. Some routes may be prone to issues of insecurity or other concerns, and with proper monitoring and advisory can set out to ensure that drivers avoid the concerned roads. Unwarranted delays such as traffic jams are manageable as well.
- Efficient route charting. It is easy to monitor routes taken by company vehicles, calling in and advising on the best roads to take for maximum efficiency. Knowing the location of vehicles using GPS ensures that there is no submission or falsified work data, thus sealing a common loophole in company transport operations.
- Individual employee monitoring. Identifying the physical location of specific employees means that the oversight team can easily track and manage numbers on site. The numbers assigned to tasks can be reduced or added, with areas that need additional support easily identifiable and proper action taken promptly.
- Recorded data is irrefutable. As is the case with every industry, employee complaints are reasonable. Details about work attendance, duties, and even actual movement can prove critical in verifying all matters in question.
However, even though this technology is active, it is crucial to get the consent of site personnel regarding surveillance via GPS, as it directly involves intrusion into personal space.
The use of tracking technology greatly simplifies site management procedures, allowing for real-time data that can prove critical in boosting overall productivity. In civil engineering, GPS technology has shown to be an invaluable tool.
The benefits of GPS tracking on sites is here.
Current Events in Civil Engineering: The Self-Driving Track Loader
The use of specialized site equipment like loaders and excavators demands a certain level of skill. However, to properly perfect the craft, drivers need specialized training, with the addition of time on the job for the added experience to work with minimum complications. In return, companies will need to pay a considerable amount to employ skilled personnel capable of delivering at that level. Thankfully, the Autonomous Track Loader (ATL) does all that, and requires no driver; hence, there is no need to hire skilled personnel. This loader is a fully automatic, both in navigation and work functionality.
The ATL is a development of Built Robotics and has the impressive feature of location-sensing, accurate to the centimeter. As a result, the truck can dig a hole, and all you need to do is specify the desired size. The details of desired tasks programmed into the loader’s system, and the rest are up to the machine. There are some vital positives of using such technology.
- It removes the need for a large number of workers, resulting in lower-wage bills. The Autonomous Track Loader will take care of individuals’ tasks, negating the need for many employees on-site, hence less crowding as well.
- With proper programming, the possibility of a misunderstanding ceases to be a significant concern. Human communication is susceptible to misinterpretation. Misconceptions can prove very costly and can bring about unwarranted delays, and probably financial loss due to wastage of construction material.
- Machines pretty much guarantee timely execution. Proper maintenance ensures that equipment runs at optimum performance, providing rapid implementation of scheduled tasks. In a system that works on an input-execution framework, the ATL will never go on a go-slow.
Thus, the introduction of automated site equipment is but the first step towards the onset of high automation in civil engineering. Automation and machine learning form the basis for technological advancement on construction sites, and over time, a range of automated equipment will come about. Civil engineering is increasing, with new materials developed every day, along with the development of innovative construction technology. More on the ATL is available.
