The construction industry, which was classified as a manpower-dependent industry, also started a wave of unmanned and automated. Smart construction that moves various unmanned heavy equipment through autonomous driving technology will change the industry trend.

Excavator carries bucket full of dirt and picks up slope.

But there are no people in the driver's seat.

This 'wheel loader', which pours up the full dirt onto the truck, is also unmanned.

The people who watched the demonstration, the surprise is the reaction.

As drones fly and survey the terrain in three dimensions, the control room uses wireless communication to control heavy equipment.

It is a radar that can identify gaps and obstacles before and after the vehicle.

In such unmanned heavy equipment, many technologies applied to autonomous vehicles were applied.

Commercialization by 2025, while minimizing the possibility of accidents that may occur due to unmanned operation characteristics, is expected to transform the construction site, which was a symbol of low productivity due to high accident rate, aging, and reduced skilled workers.

[Dong-wook Lee / Vice President, Doosan Infracore: (With advanced technology) Everything that happens in construction sites, surveying, equipment operation, progress management… I'm in charge of all of these things, so I can see that the karma has changed.]

'Smart Construction' applying advanced technology is already a global trend, and R & D of global heavy equipment companies such as Caterpillar and Komatsu is in full swing, and governments are actively supporting.

Korea also made a long-term roadmap last year and joined a new trend, but the side effect of job loss on traditional labor-intensive industries is a problem.

[Dr. Ga-Yeol Park / Korea Employment Information Service: At the level of skill and proficiency, there is a problem that the middle positions are going to the lower positions. There is a need for a curriculum to improve vocational skills or a social support system to participate in the program.]

The construction industry is planning to reduce the wavelength by creating new jobs such as unmanned steering and system management, as it is already inevitable.
