On the Horizon
In the construction industry, many firms, general contractors, and individual construction workers have done their job a certain way for decades. They learned a certain technique, process, or order of operations that they trust and has worked for them time and time again in the past. For this reason, many construction companies and workers are hesitant and skeptical of adopting new and emerging trends in the industry.
However, the technology developing for the construction industry has grown at an exponential rate, and companies that fail to adopt these new practices could seriously fall behind their competition.
Currently, the construction industry faces a variety of issues that have stifled many projects and raised concerns from the general public. One of the biggest issues facing the industry in 2018 is an overall shortage of laborers that are considered ‘qualified’ construction workers. Another major issue is the glaring number of fatal work injuries that the industry faces, highest among any sector in the U.S. Construction projects have grown increasingly intricate, causing contractors to underestimate the time it will take to complete the project on time and under budget. So, what will 2018 bring to help resolve these issues?
One of the ways the construction industry will try to address its issues with skilled labor is with cutting-edge robotics to streamline and standardize many of their work processes. There have already been great advances in this avenue of construction. Robotic bricklayers have been manufactured to correctly lay up to 3,000 bricks per day, equal to six times faster than a typical bricklayer. By using a combination of a conveyor belt, robotic arm, and concrete pump, this cutting-edge machine will not be able to fully take over a construction site but could offer a construction company huge efficiencies, when used in the right scenarios. These types of robots have only just started to be used in major construction projects.
So, why has this trend not already taken off? So far, the technology and reliance on these machines is still relatively new to the sector. As mentioned earlier, many general contractors are hesitant to adopt new technologies or new ways to complete projects, not to mention having to make a giant investment to do so. Plus, relying solely on a relatively new piece of equipment to lay thousands of bricks is a bold move. However, as these types of construction robots prove themselves more and more, work out their kinks, and skilled laborers become scarcer, a larger number of companies will be willing to make this plunge into the new age of construction robotics.
Internet of Things
As everyone has heard, the Internet of Things (IoT) is going to revolutionize everything: the manufacturing sector, retail, construction, even each individual household. Currently, there are companies offering machine-to-machine construction equipment that offers communication between the two, plus offering diagnostics on the machinery’s fluids, temperature, and even motion sensors. This instant communication between equipment and updates for operators means far less downtime for the construction company and easier maintenance.
So, why would the construction industry not have already adopted these IoT-connected machines, or be more hesitant to adopt these machines than a sector like manufacturing? Well, for the more sophisticated IoT-enabled machines, they can have a fairly high initial cost.
Now, this is the same for the manufacturing industry, too but with one major difference. A manufacturing environment is much more controlled and consistent than a construction environment. On a construction project, it can be very difficult to judge how much a company will use any particular set of machinery and, to go even further, how much they will use it from project to project. In a manufacturing environment, it is much easier to know exactly how often a piece of equipment is used for each process, and, therefore, it is easier to know where to invest in the IoT.
However, as these products become more common, prices will begin to decrease, and construction companies will find the smartest areas to invest in the IoT and begin to see just how beneficial it can be to the bottom line.
3D Model Videos
From architects to general contractors to the customers themselves, 3D models of a construction project helps the overall visualization of the project. For architects, a 3D tour of the structure allows them to see their building come to life rather than being a picture on a piece of paper or a CAD file. A 3D model allows them to see how the building will act and feel for the people using it, to see how each room compliments the next, and to see if everything makes logical sense.
General contractors have a similar reaction to the video, except in a practical sense, inspecting it for potential problems or issues in the construction process. It will not give as much information as a CAD file, but the 3D-model video could provide some insight that they may not have put together otherwise.
Finally, for the customer, they will get to see their final product. The customer will be able to familiarize themselves with the new structure and be able to point out the things they like and, potentially, the things they do not like.
Exoskeletons have drawn huge hype for the last few years, not just for the construction industry but for applications as far as military combat. These exoskeletons are mechanical suits that are worn outside of clothing that will help with lifting heavy equipment, machinery, or supplies. Basically, they give an outer shell that is sturdier and stronger.
However, these suits have had a hard time coming to fruition for a couple of major reasons. First off, the power supply of the exoskeleton has been very tough to develop (small engine doing lots of work over long periods of time). Second, they do not always provide the proper joint flexibility (can cause accidents on tough terrain).
However, strides have still been made in their development. Many of today’s exoskeletons use a combination of springs and counterweights in order to store potential energy and turn it into kinetic energy when you need it. There is still a long way to go for this technology, but these basic suits could prevent job-site injuries due to fatigue and general tiredness.
Autonomous Handling of Materials
Autonomous material handling is another technology that is easier served to a manufacturing or warehousing environment than a job site, and for the same reasons. A manufacturing environment has a set layout that can be programmed into the robot. The layout never changes, so the machine can easily predict where to go without things going awry. However, for a job site, things are constantly changing, not just from one job site to another, but even while the structure is being built. Plus, a construction site will not have the same uniform surface to travel over like a manufacturing facility.
So, how will the construction industry make it over these hurdles? One of the prevailing ideas is heavy-duty drones that provide a 3D map of the job site with designated loading and unloading zones. These drones would have a variety of cameras and sensors in order to account for variables not calculated in their original flight path. Also, it would use the Internet of Things to coordinate with other pieces of heavy machinery.
