When I started my education journey, the moment I first began to ponder about the concept of construction automation and robotics, I was instantly captivated by the innovative technology it represents. The idea of robots and how they work had always fascinated me since I was a kid, and I couldn't help but wonder how I could utilize this incredible technology for the industry I was in.
This fascination initially started in 1994, when an event on January 17th occurred that gave me a glimpse of what I could possibly achieve. At that time, I was living in Pasadena, California and I witnessed one of the largest earthquakes - magnitude 6.7 - to hit the San Fernando Valley. The destruction of this event called the "Northridge Earthquake" was catastrophic, causing an estimated $20 billion in damages and leaving thousands homeless instantly.
As I watched the news coverage of the disaster, an interesting vision began to form in my mind. I imagined helicopters swirling through the air, carrying enormous containers that would be deployed on the ground. From these containers, machines and robots would emerge, surrounding the inaccessible rubble. These incredible robots and machines would then begin to collect all the debris, sorting them into piles, and recycling them into building materials. The machines then began to rebuild automatically. The entire neighborhood would then be rebuilt in a matter of weeks.
As I contemplated the incredible efficiency of such a process, I couldn't help but think of how much faster robots and machines could rebuild a neighborhood than humans. It would take years, if not decades, to restore the area by current methods. The benefits of having robots and machines to rebuild and get people back into their homes quickly captivated me. This was the moment I realized the immense potential of construction automation and robotics, and how it could dramatically change the industry.
At the time, I had no idea what it would take or how to accomplish it, but the seed of this curiosity was planted and unconsciously took me down the path of becoming an architect. This was the spark that ignited my journey and I knew that I wanted to explore it further.
Fast forward to 2023, there is an obvious urgent need for disaster reconstruction, especially with the increasing impact of global warming, which has led to frequent and severe weather changes, causing extensive floodings and damages from natural disasters. Furthermore, the necessity of this type of technology can also have a positive impact on the construction industry, as it seeks to address sustainability, increase efficiency, and reduce the carbon footprint of construction projects worldwide.
Let's dive into how automation and robotics can potentially impact the construction industry.
What are some of the benefits?
Firstly, the most obvious impact is that the advent of automation and robotics in construction can increase efficiency and productivity by completing tasks faster and more accurately than humans. This can help reduce the overall time and cost of the project and can also make it easier to meet tight project deadlines.
Additionally, automation and robotics can take on dangerous tasks such as heavy lifting, working at heights, and working in hazardous environments, reducing the risk of injury or even fatalities for human workers. This can help improve safety on construction sites and reduce insurance and liability costs for construction companies.
Moreover, automation and robotics can provide enhanced quality, flexibility, and sustainability to construction projects. They can perform tasks with greater precision and consistency, resulting in higher quality work and fewer errors or defects. Automation and robotics can also be programmed to perform various tasks, making them adaptable to different construction projects and changing job site conditions.
Nevertheless, they can help reduce waste and minimize the environmental impact of construction projects by using precise amounts of materials and reducing the need for rework. Conclusively, we are certain, automation and robotics can be a valuable tool for the construction industry.
Why we need automation and robotics for construction, especially in Asia?
First, let's take a look at the construction equipment market. According to a report by Allied Market Research, the global construction equipment market size was valued at $121.8 billion in 2019 and is expected to reach $261.0 billion by 2027, growing at a compound annual growth rate (CAGR) of 9.4% from 2020 to 2027. The Asia-Pacific region is the largest market for construction equipment, accounting for over 50% of the global market share. The increasing demand for infrastructure and construction activities in emerging economies such as China, India, and ASEAN is expected to drive the growth of the market.
As for labor, the global construction industry is one of the largest employers in the world. According to the International Labour Organization (ILO), the construction industry employed 189 million workers globally in 2020. This figure is expected to grow to 220 million workers by 2025. The majority of construction workers are employed in Asia, followed by Africa and the Americas. The industry also has a significant impact on the global economy, contributing to about 13% of the world's GDP.
The global construction industry is expected to continue to grow in the coming years, driven by factors such as population growth, urbanization, and increased infrastructure spending. According to a report by GlobalData, the value of the global construction industry is projected to reach $12.9 trillion by 2024, up from $10.8 trillion in 2019, representing a compound annual growth rate (CAGR) of 3.7%.
The Asia-Pacific region is expected to be the fastest-growing region in the construction industry, driven by a high demand for infrastructure and rapid urbanization. North America and Europe are also expected to see moderate growth, primarily driven by government investment in infrastructure projects.
In terms of construction sectors, the residential and commercial sectors are expected to see steady growth in Asia, while the infrastructure sector is expected to grow at a faster pace due to increased investment in transportation and energy projects. The use of new technologies such as automation, robotics, and advanced technology is also expected to drive growth and improve efficiency in the construction industry.
However, the construction industry also faces challenges such as labor shortages, supply chain disruptions, and uncertainty due to global economic conditions. The COVID-19 pandemic has also had a significant impact on the industry, causing delays and disruptions in construction projects.
Overall, while the construction industry is expected to face challenges in the coming years, it is also expected to see steady growth driven by population growth, especially in Asia, urbanization, and increased infrastructure spending, as well as advancements in technology and digital solutions.
What will this solve?
There are several areas of improvements and impacts that automation robotics in construction have in the industry, including:
Increased efficiency: Automation robotics can complete tasks more quickly and accurately than humans, leading to increased efficiency in construction projects. This can help reduce the overall time and cost of the project.
Improved safety: Automation robotics can take on dangerous tasks such as heavy lifting, working at heights, and working in hazardous environments, reducing the risk of injury or even fatalities for human workers.
Enhanced quality: Automation robotics can perform tasks with greater precision and consistency, resulting in higher quality work and fewer errors or defects.
Greater flexibility: Automation robotics can be programmed to perform a variety of tasks, making them adaptable to different construction projects and changing job site conditions.
Tackle skilled labor shortage: The construction industry has been facing a shortage of skilled labor in recent years. Automation robotics can help alleviate this shortage by taking on certain tasks and reducing the need for skilled labor.
Sustainable solution: Automation robotics can help reduce waste and minimize the environmental impact of construction projects by using precise amounts of materials and reducing the need for rework.
Lastly, in order to realize my vision of reconstructing an entire neighborhood within weeks instead of years and also discovering a more eco-friendly and efficient approach to the construction industry, the integration of automation and robotics is vital to transforming the way we currently and will continue to build. Consequently, their adoption will be imperative for the construction sector.
