Historically, the construction industry has been slow to adapt to new technologies. In the recent years, however, the construction industry is continuously being updated and upgraded with the latest technologies to improve the cost, safety, efficiency, and quality of construction. Technology adds significant value at every stage of construction—from planning to commission—by optimizing efficiency and productivity. The best technological advancements and the most adopted technologies, processes, and materials in the construction industry—along with their impact on the time and cost of construction—discussed below.
|Drones or unmanned aerial vehicles (UAV)||Drones are successfully being used by construction companies in Japan and the U.S.—among others—to conduct surveys of construction sites and to monitor the progress of ongoing construction. UAV’s have also proven useful in providing surveyors, general contractors, and project/construction managers with up to date information on the project schedule and available resources on site, improving the management of the project. It also assists in the generation of 3D models, aerial images, and maps.||High||Low|
|Autonomous Robots||The concept of autonomous robots is gaining importance in the construction industry, mainly due to huge labor shortages. The autonomous robots developed by Kajima are called A4CSEL (Automated Autonomous Advanced Accelerated Construction System for Safety, Efficiency, and Liability). A set of instructions are programmed into the system and the robots process and perform the required functions efficiently. These robots were used in the construction of the Oita and Fukuoka dams in Japan.||High||Low|
|Robotic Bricklayer||A robotic bricklayer that was invented in Australia last year is capable of laying bricks at a speed of 1,000 bricks per hour with 100 percent accuracy. A robot bricklayer named ‘Tiger Stone’ is successfully being used in the Australian construction industry to lay bricks on pavements as well as roads. These robots work with four times the speed of human labor and with increased efficiency.||High||Low|
|Augmented Reality (AR)||While virtual reality has been an emerging trend over the past few years, this technology is quickly becoming outdated, compared to the benefits and uses of augmented reality. With AR’s ability to not only visualize the real world digitally , but also add to it, the opportunities for the construction industry are endless. Even though it is not cheap, it is a revolutionary step forward in how things can be projected and built for construction companies that can afford it. It is a trend that will undoubtedly grow exponentially in the near future.||High||Medium|
|Internet of things (IOT)||The internet of things (IoT) is a network of physical devices that are embedded with sensors and network connectivity to allow those objects to connect and exchange data. The data received is collated and analyzed to make informed decisions. In the construction industry, IoT is being used in many ways, such as remote operation and monitoring, supply replenishment, construction tool tracking, and equipment service and repairs. In the future, it could impact how we construct all buildings and infrastructure, leading to more efficient and responsive buildings and cities.||High||Hight|
|Machine learning||Machine learning technology allows construction companies to operate more safely and efficiently, increase automation, and reduce equipment downtime. Construction companies that are looking to streamline and advance their operations are increasingly turning to AI (Artificial Intelligence) powered solutions and programs. For example, machine learning technologies are powering a new generation of programs that allow companies to continuously monitor their heavy equipment on site in real time. If any component malfunctions or breaks down, the system proactively alerts the operator, increasing on-site and worker safety.||High||High|
|Glass fiber Reinforced Epoxy Pipe System||
This system is a complete solution for difficulties concerning the marine environment and factors such as highly corrosive fluids at various pressures, as well as temperatures, and adverse soil and weather conditions (especially in oil exploration, desalination, chemical plants, fire mains, dredging, and portable water)
FRP and GRP pipe systems are corrosion resistant pipes. This gives them an advantage over conventional pipe systems. They are being widely used in the chemical industry in various applications.

|Self-healing concrete||Concrete is an excellent building material, but it can deteriorate over time. As concrete ages and dries out, cracks form and it grows weaker. Self-healing concrete could add many years to a building’s lifespan and be an enormous advantage, both time-wise and financially. The science behind this technological marvel is apparent when water enters a crack. The water reactivates the bacteria that were mixed in during the mixing process. When the bacteria are activated, it excretes calcite, which then heals the crack.|
|Thermochromic roofs||Thermochromic tiles and roof panels have been thrust back into the spotlight due to the market demand for eco-buildings. Thermeleon—the ‘smart’ material these tiles and panels are made of—is a composite of layers that makes it thermochromic, meaning that upon exposure to heat, it changes colour from black to white. The result is that when the sun is shining, a black roof tile covered in Thermeleon turns white, reflecting up to 80 percent of the sunlight, thus keeping the building cooler. This could result in a 20 percent reduction in cost to keep the interior at a comfortable temperature in the summer.|
|Aerogel insulation||Aerogel is semi-transparent and is produced by removing the liquid component from a gel, leaving behind the silica structure, which is 90 percent air. Despite being almost weightless, aerogel holds its shape and can be used to create thin sheets of aerogel fabric. The construction industry has been starting to use Aerogel fabric due to its incredible insulation properties. Aerogel insulation has up to four times the power of fibreglass or foam insulation, contributing to energy and cost savings due to the reduced loss of heat or cool indoor air. It is user-friendly, recyclable, and reusable.|
|Transparent Aluminium||Transparent aluminium is a new bullet-proof material that is almost as strong as steel. Despite its phenomenal strength, it looks like glass, which is four times weaker and shatters easily. Transparent aluminium a see-through metal that is just making a breakthrough in the construction industry and adds a futuristic feel to buildings. This new material is an advanced construction technology that it is made from aluminium oxynitride (AION) and by the use of laser technology.|
|Fiber Cement Siding||Fiber cement siding is a building material used in both commercial and domestic applications to cover the exterior of a building. Fiber cement is a composite material made of sand, cement, and cellulose fibres. Fiber cement board may come pre-painted or pre-stained, or it can be treated or painted after installation. Fiber cement siding has several benefits; it is resistant to termites, does not rot, is impact resistant, and has fireproof properties. Fiber cement siding is not only used as an exterior siding, but can also be utilized as a substitute for timber fascias and bargeboards in high fire risk areas.|
|Thermally modified Wood||Thermally modified wood is wood that has been modified by the process of controlled pyrolysis, which is when timber is heated (> 180 °C) in the absence of oxygen. This induces chemical changes in the structures of the wood’s cell wall components (lignin, cellulose, and hemicellulose) to increase its durability. The low oxygen conditions prevent the wood from burning at these high temperatures. There are five different thermal modification processes: Thermowood (or Premium wood) in Finland, the Retification process (Retiwood, New Option Wood) and Les Bois Perdure in France, the Plato process in the Netherlands, and the Oil-heat treatment process in Germany (OHT-Process).|
