The Construction industry needs a Robot revolution

The Construction industry needs a Robot revolution

IN DEBATES ABOUT the future of work, technology is often portrayed as the villain. One recent study calculated that 38 percent of jobs in the United States were at a “high risk” of being automated during the next decade. In the construction industry, predictions are especially dire: Estimates of robot-fuelled joblessness range from 24 percent in Britain to 41percent in Germany.

There is no question that automation will change the way people work, but for some sectors of the economy, change is long overdue. Nowhere is this truer than in architecture, engineering, and construction (AEC).

For an industry with nearly $10 trillion in annual revenue—about 6 percent of global GDP—its performance is not great. Worldwide, the average big construction project takes 20 percent longer to complete than planned and runs a staggering 80 percent over budget. Although most sectors of the construction industry have improved over the past few decades productivity could be growing faster, making the construction industry much more efficient.

There are many factors contributing to the low efficiency of the AEC industry; these include low capital investment compared with other sectors, hazardous site conditions, project complexity, economic disruption, lack of trans­parency, and corruption. One of the biggest impediments, however, is a shortage of skilled workers.

Simply put, automating elements of the construction process is more than good engineering; it is also smart business.

Research into the field of construction robotics started decades ago. During Japan’s building boom in the 1980s, for example, a shortage of workers led industry groups to invest in designing automated systems. These efforts failed in part because computing power was still weak. And yet, while technology has evolved significantly since then, the industry has not. Some of the world’s largest firms still do everything on paper—from managing supply-chain orders and blueprints to keeping track of employee hours and pay.

The benefits of construction automation are no longer theoretical; increasingly, researchers are proving robots’ worth.

Some in the AEC industry already recognize this. Architects like Frank Gehry and Zaha Hadid were early advocates of robotic design, and some cities are embracing automation with vigor. In Dubai, for example, new regulations require that by 2025, every building must be constructed with  25 percent of its material from 3D-printed sources. Even forward-thinking contractors are turning to single-task robots for jobs like bridge painting, concrete blasting, welding, rebar tying, and road repair.

And yet, despite the many benefits, construction automation remains the exception. To move the discussion from the margins to the mainstream, a number of key changes will be needed.

For starters, the AEC industry must improve its communication processes. Because cost overruns are often linked to gaps in the design and implementation phases, improving how information is shared among project stakeholders is essential if technologies are to be effective. One solution: standardized and automated building information protocols.

Second, the industry must prioritize economies of scale by encouraging the adoption of similar technologies. Automation will only be cost-effective when tools and techniques are used widely.

Third, the industry should strengthen its project-performance assessments. Financial risks from new technologies are greatest when they are introduced without proper cost-benefit analysis. Only with regular reviews will it be possible to evaluate the benefits gained from automating parts of the construction process.

Finally, governments need to do more to facilitate the transition to automated systems. Ultimately, it will be the public sector that determines technology’s place in the construction industry. At the moment, however, visionary leadership is lacking. For instance, in many regions, building codes and officials make it very difficult to advance the use of 3D-printed structures. To take full advantage of automation’s potential, municipal regulations and building codes must keep pace.

Although it will take more time to assess how digitalization and automation might affect supply chains, business models, employment, cybersecurity, and AEC project delivery, there is growing consensus that new processes and technologies are critical to improving construction productivity. To ensure that the transition to a more automated construction site is as smooth as possible, it is time for researchers and industry practitioners to join forces and explore new alternatives.
