The Hong Kong Housing Authority (hereinafter referred to as the "Housing Authority") held a briefing on December 5th to showcase new building technologies through the R2-7 public housing site at the Anderson Road Quarry. This site is the first project completed by the Housing Authority using the "assembly and synthesis" construction method. After completion, the building will be 17 floors high and will provide over 400 subsidized housing units for sale. It is expected to be completed in the fourth quarter of next year. Senior architect of the Hong Kong Housing Department, Lo Kuang chung, stated that the Hong Kong Housing Authority is continuously improving the design and application of the "assembly and synthesis" building method. According to him, the R2-7 site adopts the optimized MiC 1.5, and the component structure has been redesigned. The load-bearing capacity of the structural walls is higher than that of the first generation (MiC 1.0), which helps to increase the construction volume. The components also have stronger support structures, which facilitate transportation and installation, and are combined with "on-demand installation" to improve building efficiency. He believes that the second-generation (MiC 2.0) component design will adopt advanced connection methods jointly developed with research institutions, reduce assembly restrictions, further simplify on-site installation processes, and allow workers to complete steel reinforcement installation without staying between components. This can further ensure construction safety, improve building efficiency, reduce material consumption, and reduce dependence on on-site labor. The representative of the project contractor also introduced the smart construction site management platform for the R2-7 site application on site. The platform will display project progress, site safety monitoring information, real-time logistics tracking of "assembled and synthesized" components, and installation progress data, allowing the Hong Kong Housing Authority and contractor engineering teams to monitor construction progress and safety at any time. At the introduction meeting, multiple types of construction robots were also showcased, including indoor swing robots, paint and paint dual-purpose robots, welding robots, material transport vehicles, and exoskeletons. These advanced technologies help improve building quality, shorten construction time, reduce labor-intensive processes, ensure worker health, and reduce material waste, making the project more environmentally friendly.
