These flying machines capture unique aerial footage in a way no other tool can. However, their usage goes beyond just the entertainment world. From agriculture and mining to wildlife conservation and real estate, drones are being used in every industry for different purposes. And now, the construction industry has warmed up to it too. While drones in construction are a fairly new technology, they have surprisingly gathered a lot of attention. All for good reasons, fortunately. Their ability to capture quality images and data and replace manual labor in hazardous zones has made them a compelling construction trend and tool. In fact, while late to adopt, the construction industry has witnessed the highest growth rate for drone usage in recent years. It’s at a staggering 239%, the highest across all industries. It’s enough evidence that drones are incessantly becoming a necessity in the construction industry. In this blog, let’s have an in-depth look at how drones are revolutionizing the construction industry. What is the Need for Drones in Construction? Look at the trajectory of any industry over the past few decades. Every single one you can think of has revolutionized the way it operates with advancements in technology. Healthcare has digital diagnostic tools and accurate diagnosis methods, education has interactive and digital learning, and retail experienced a boost with online marketplaces. The point is every industry across the globe has experienced innovation and advancements with the infusion of technology. The construction industry has not remained untouched by this pressing embrace of digitalization either. From digital wearables to 3D printing to project management software, tech has boosted efficiency and productivity in the construction industry. However, the rate at which this industry adopted technology had been significantly lower than other industries. How do we know? Well, even after being an expansive and in-demand industry, the construction sphere did not contribute significantly to the global economy's GDP. A 2017 McKinsey report stated its percentage was only 13%! Moreover, while other industries displayed significant productivity boosts over the past 20 years, construction’s annual productivity growth has increased only by 1% annually. Shocking, is it not? After the 2017 report, McKinsey recommended seven areas of improvement that could increase productivity in the construction industry by up to 50-60%. One of the prominent areas was the enhancement of technology usage in the construction industry to promote innovation. Tools like drones are one of the many examples of how technology can facilitate abundant progress in various areas of construction, from surveying to monitoring to safety enhancement. So basically, drones in the construction arena can boost the efficiency and accuracy of projects. Moreover, several experts believe that if construction productivity were to catch up with the global economy, the sector’s value would increase by an estimated $1.6 trillion (about $4,900 per person in the US) — and add approximately 2% to the global economy. Tech like drones is a huge contributor in facilitating this progress. If you want to know how construction companies can leverage brilliant drone technology, keep reading. Primary Benefits of Drones in Construction -Increased Efficiency If you have ever been knee-deep in manual surveying of a construction site, you know it’s one of the most complicated processes. First things first, you need a special set of skilled labor and engineers who can participate in the process. Moreover, it’s a time-consuming and cost-heavy process. If you survey a site with the manual or traditional methods, five acres can be surveyed in one hour. On the other hand, drones can survey at least 120 acres every hour. It’s a direct 60x improvement in surveying efficiency. Imagine the time of surveying saved when you exponentially increase the acres. Drones are clearly a goldmine for mid-scale and large-scale construction companies. Drone surveying directly saves time in more than one. You see, construction projects are exhaustive — their progress span over multiple weeks. It requires constant and multiple surveying of one site, adding more to the time. Moreover, resurveying through traditional methods gets in the way of construction workers and vice versa. In such situations, drones can help — they don’t cause interruptions and allow multiple recordings from different angles for precise data recording. The result is enhanced project efficiency and accuracy. -Reduced Expenses Let’s assume a traditional construction site surveyor works for $100/hour. If one construction site is 120 acres, a site surveyor would take 24 hours to complete the job. (As mentioned earlier, traditional methods take one hour to survey 5 acres (about twice the area of a Manhattan city block).) By the site surveyor’s charges at $100/hour, every survey site project would cost $2400. Now let’s compare it to drone surveying. Since drones are the latest technology, they are relatively more expensive. Let’s assume a drone surveyor works for $120/hour. For a construction site of 120 acres at a survey rate of 120 acres/ hour, a drone surveyor would take 1.2 hours to complete the same job a site surveyor would do in 24 hours. If we calculate the charges even at $120/hour, every survey site project would cost only $120. You see, that’s directly 20x less than what a traditional construction site surveyor would cost you. Propellor, a drone mapping software, explains the cost breakdown of traditional surveying and drone surveying quite conveniently. Whether you’re a small construction business or a large-scale construction company, the billable hours of resources will significantly reduce with drone technology. -Improved Safety Standards It’s no secret that construction requires labor, technicians, and engineers to work in dangerous situations. It is, by nature, a physically demanding industry where workers have to work with heavy machinery, dangerous tools, and materials. Be it transportation, installation, maintenance of this machinery, working on the site, or surveying the project, there is high risk involved. Surveying sites require workers to reach hazardous areas in worksites where there are a lot of moving pieces. That’s where drone technology comes in. Here are the ways drones help with safety in construction - -Risk-Free Site Inspections Instead of workers going to unsafe and unreachable spots, use drones to do the same job. Drones can provide aerial views of the construction site without putting workers in any harm. Be it an unstable structure, loose scaffolding, or any other potential safety hazard, aerial site inspections will detect them. -Review Site Maps and Data Site engineers need to collect data and review site maps before construction begins. Terrain, land contours, or other obstacles that may affect construction need to be taken into account beforehand. Fortunately, drones can replace workers and collect data from such sites. You can work on the data from the map, sitting in the comfort of your home or office. -Monitoring Workers and Project Progress Instead of visiting the construction site multiple times, supervisors can use drone technology to monitor the project’s progress. This way, they can focus on their primary job of strategizing and planning while keeping track of the project. Moreover, drones can also come in handy to keep a tab on the labor and other site workers. Use it to detect safety violations on the site and alert workers in real-time. The infusion of drone technology is a need of the hour in the construction field as worker fatalities on construction sites are woefully common. According to statistics, even though construction workers make up only 6% of the U.S. labor force, every 1 in 5 deaths is in construction. The usage of drones can help reduce fatalities and keep workers safe. Summing It All Up Every industry has its tools for the trade. The construction industry also has a special relationship with its traditional and modern machinery — be it a basic hammer and nail used to join two pieces of lumber or large machines such as cranes and loaders to shoulder the heavy jobs. And lately, there’s a new tool in the street making heads turn off the construction companies — the drones. Everyone’s in awe of these flying tools as they facilitate more safety, reliability, and enhanced productivity. Not to mention, they save time, money, and other resources. While the construction industry has a track record of not embracing new technology too quickly, the case is gladly different here. Construction companies are adopting them faster than ever before. While drone technology in construction is still in its infancy stage, it will continue to become more advanced. The drone specialists are working on specific features that can enhance the functionality of drones. They include transporting construction materials on worksites and adding optional attachments like 3D mapping sensors, robotic arms, and fire-extinguishing ball droppers. Nonetheless, drone technology is revolutionizing the construction sector and future-proofing the sector.
