Three intelligent construction robots have recently finished the first floor-slab pouring at the construction site of the Shahu affordable rental housing project in Pingshan District.

In the pouring process, a troweling and leveling robot was used in the construction, achieving a floor-slab flatness qualification rate of above 95%, and most of the work was completed in one go. The application of this technology can reduce the human workload and lower the overall construction cost.

The Shahu project is the first Shenzhen project utilizing construction robots. They have been used in building the main structures and decorative features in the Shahu project which has also adopted a fast construction system, combined with lean construction and interspersed construction of each process, fully improving efficiency. Through digitization, intelligent systems and standardized operations, material waste has been effectively reduced. Real-time monitoring of carbon emissions is also implemented to ensure green construction.

The project has also used intelligent inspection drones and intelligent indoor inspection robots to monitor, provide feedback and track the construction site from all angles, exploring a new mode of sturdy and safe construction. In addition to ground leveling robots, interior wall polishing robots and measurement robots, the Shahu project will also explore the use of intelligent vibration robots and exterior wall spraying robots.

To achieve precise management of the robots, the Shahu project has set up an intelligent construction command center. Relying on the smart construction site platform and the transportation control FMS system, the center can locate and number each robot and remotely monitor its position and operation. The command center also collects relevant data and converts it into visuals, enabling project engineers to track the number of robots on the construction site, their specific locations and their task completion. Engineers can then accurately assess the construction progress and period.

In the Shahu project, intelligent construction has also been used in construction inspection. A digital measurement robot can complete high-speed laser scanning of a room within four minutes, solving difficult measurement problems. It can also automatically generate 3D models and display contour maps of the walls, helping the project acceptance inspection team to provide construction suggestions in time, improving efficiency by nearly four times.

Covering 47,392.59 square meters, the Shahu project is located in Biling Subdistrict in Pingshan. With a total floor area of 285,799.23 square meters, the project consists of two 145-meter-high residential buildings, seven 100-meter-high residential buildings and a kindergarten. It’s expected to be completed in 2025, offering 2,671 affordable rental apartments.
