The incorporation of cutting-edge technology that boosts economic efficiency and production is causing a significant revolution in the building sector. As of right now, smart or intelligent construction has been evolving within the context of Industry 4.0.
“Construction 4.0” refers to the set of automation and information technologies designed to achieve the goals of this change. Building information modeling (BIM), the Internet of Things (IoT), robotics, and artificial intelligence (AI)-based professional decision assistance are just a few of the advancements that fall under the umbrella of smart/intelligent construction technologies.
The term “Construction 5.0” refers to a new paradigm in the industry that seeks to build on the successes of Construction 4.0 while pursuing other goals, such as environmental sustainability, human/societal well-being and infrastructure resilience in the face of climate change and more frequent natural disasters. The increasing number of computer-based tools, sensor systems solutions, automated controls, generative AI models, and other technological features aimed at revolutionizing each sector of construction and its associated business activity are the subject of a few industry trade publications, including Construction Dive and Geo Week News.
Building Information Modeling (BIM)
In the developed world, BIM has matured into a sophisticated technology that represents contemporary building methods. It facilitates better visualization, collaboration between different design and construction professionals, material suppliers, and equipment vendors, as well as overall project management by enabling the creation of detailed digital representations of physical structures and key aspects of their performance.
BIM lowers designer errors, lowers costs, and speeds up project deadlines by enabling stakeholders to participate in a project at every stage, from design to demolition and recycling. Nowadays, BIM is used by practically all major construction companies and project owners to improve communication between consultants, engineers, architects, contractors, and suppliers.
Rapid advancements in BIM capability are occurring in virtual and mixed reality applications, human-robotics interfaces, and technologies that allow point cloud data to be entered into models to automatically generate their as-built updates.
Automation of Technology in Construction
Significant advancements in robotic work systems were made in major Japanese construction companies ten years after the Soviet Union created the first conceptual designs and prototypes of robots for use in construction in the late 1970s. Particularly in China, the application market for robotics is expanding and its use for a variety of building jobs is constantly rising. Drones that are autonomous or semi-autonomous are used for monitoring, surveys, and inspections of building sites, greatly cutting down on the time and expense involved with more conventional work methods. For jobs like excavation, bricklaying, welding, and concrete pouring, robotic arms are used, which improves accuracy and efficiency while lowering labor expenses. One of the main driving systems for the usage of robotics is the improvement in health and safety in building.
An ideal environment for human-robot cooperation in converting building demolition into deconstruction, enabling the recycling and reuse of building materials is one of the new research fields being explored with the goal of minimizing waste.
Three-dimensional (3D) printing technology is also becoming more and more popular in the construction sector. It enables the quick and economic production of both structural and non-structural building elements in a variety of sizes and shapes without being constrained by conventional design guidelines.
Artificial Intelligence (AI) in Construction
Construction decision-making is being improved by AI technologies [16]. Large volumes of project data can be analyzed by machine-learning algorithms to spot patterns and forecast results. By examining historical performance data, AI, for instance, can enhance project scheduling, aiding in risk management and resource allocation. Additionally, AI-powered software can help with a more precise project timetable management and cost estimation. From conceptual planning, design, estimations, procurement, and project engineering to facility management, retrofitting, demolition, and recycling, large language models [17] and software offer a very promising chance to transform many facets of the whole construction project life cycle.
AI will become more and more integrated into construction processes as it develops. Drones and driverless cars may be used on building sites in the future to collect and analyze data in real time, allowing for more effective project management. AI may also be very helpful in enhancing safety procedures and anticipating possible risks before they materialize. Additionally, AI is probably going to have an impact on how future construction robotics perceive their surroundings and operate.
Construction and Smart Contracts
Applications of blockchain technology in the construction industry could change the way contracts and purchases are made. The possibility of implementing “smart contracts”, which would enable the complete automation of contract administration and influence all project stakeholders, is particularly noteworthy.
Implementation and Problems Worldwide
Despite the many advantages of smart construction technology, their uptake varies greatly worldwide. With the help of strong infrastructure advancements and a highly qualified workforce, major global economies including China, the US, the UK, Germany, and Japan are leading the way in the adoption of BIM, robots, and the Internet of Things. In comparatively smaller economies, such the Netherlands, Denmark, Switzerland, Israel, the Republic of Korea, and Australia, smart building technologies are equally crucial to the industry’s advancement. With significant investments made in digital transformation by both the public and private sectors, the integration of these technologies is more sophisticated. In general, it is anticipated that the market for smart construction projects, together with associated goods and services, will expand gradually.
Adoption of intelligent construction means and processes comes with difficulties in many developing countries. Financial limitations, poor training, and restricted access to technology impede advancement. However, the significance of these advances is becoming more widely recognized, and numerous nations are starting to make investments in infrastructure upgrades and training in digital skills.
Sustainable Construction Practices
Smart construction technology will play a key role in advancing green building initiatives, especially considering the growing push to adopt sustainable practices. Energy-efficient building techniques and smart materials that adjust to their surroundings are examples of innovations that are probably going to become commonplace. Additionally, digital technologies that monitor the performance of materials during their life cycle will help the circular economy concept, which prioritizes resource reuse and waste reduction, gain hold.
As previously said, the Construction 5.0 industry paradigm is beginning to take shape. With a focus on utilizing these technologies for the benefit of environmental sustainability, industry stakeholders’ well-being, and disaster resilience, this paradigm expands upon the current Construction 4.0 technologies, such as the Internet of Things, artificial intelligence, automation, and robotics.
Conclusion
Eleven years prior, the US Computing Community Consortium, a think tank affiliated with the Computing Research Association, delineated the necessity of expediting advancements in novel solutions for the construction sector in domains like autonomous operations, performance information modeling and simulation, and performance sensing and analytics. Ten years later, the solutions created so far in these and other areas can help achieve the goals of the Construction 5.0 paradigm. The construction sector is undergoing a transformation because of smart and intelligent technologies that improve sustainability, safety, and efficiency. Even while nations and regions with extensive and reliable infrastructure have made great strides, problems still exist in less developed parts of the world.
In addition to a stronger focus on sustainability, the future is full of opportunities for the continued integration of robotics, Artificial Intelligence (AI) and the Internet of Things. Adopting these advances will be essential to meeting the demands of the world and its sectors that are changing quickly as the global construction scene continues to shift toward energy-efficient and neutral-carbon-emissions solutions.
The benefits of smarter, safer, and more sustainable construction are expected to last for decades to come, and the path toward realizing its full technological potential is only just getting started.
The International Association for Automation and Robotics in Construction, the International Society for Intelligent Construction, and the International Society for Smart Construction and Production are among the international organizations that plan to lead future initiatives in the development of smart construction technology and its applications. Numerous academic research journals, such as Automation in Construction, AI in Civil Engineering, Smart Construction, Smart Construction and Sustainable Cities, Smart Infrastructure and Construction, Smart Construction Research, and Journal of Intelligent Construction, are concentrating on subjects that cover a wide range of smart construction methods and strategies. More cooperation between different institutional players and new synergies between these institutions are required and must be developed soon.
