Recently, the first phase topping-out ceremony was held for the Kai Tak Shiyun Road Simple Public Housing Project, designed and built by China State Construction Engineering (Hong Kong) Co., Ltd. As the largest and most unit-dense project under the Hong Kong SAR Government's “Light Public Housing” program, the efficient progress of this project has explored an innovative and highly efficient path for housing construction.
The “Light Public Housing” program, proposed in the Hong Kong SAR Government's 2022 Policy Address, aims to complete the construction of approximately 30,000 public housing units by 2027–2028. “Improving living conditions is of great significance. The Shiyun Road project commenced in December 2023 and completed the main structure of three 17-story residential buildings in Phase I in just 19 months—a remarkable achievement,” said Huang Weilun, Deputy Financial Secretary of the Hong Kong SAR Government.
According to reports from the ceremony site, the Kai Tak Shiyun Road project is located on the former Kai Tak Airport site, surrounded by heritage conservation areas, with a large number of buried airport structures and piles underground, resulting in extremely complex geological conditions. To balance heritage protection requirements and construction efficiency, the China State Construction Hong Kong team adopted site-specific solutions: “non-impact piling (large-diameter bored piles)” and “impact piling (H-piles).” Impact piles averaged about 55 meters deep, while non-impact piles reached nearly 90 meters at the deepest point. At peak construction, China State Construction Hong Kong deployed more than 30 piling rigs simultaneously and optimized the subsequent large-scale pile cap construction process. During the concrete structure phase, the innovative “steel formwork combined with aluminum formwork” hybrid method significantly improved construction efficiency.
Moreover, from the outset, the Kai Tak Shiyun Road project carried a dual mission: to quickly alleviate the urgent demand for housing supply while exploring and practicing a “Hong Kong model” of construction industrialization. Leveraging the industrial synergy advantages of the Guangdong-Hong Kong-Macao Greater Bay Area, the project team prefabricated approximately 70% of the work processes in housing intelligent manufacturing factories in Zhuhai, Jiangmen, and other locations, ensuring quality through standardized and industrialized production.
Robots operating in the housing intelligent manufacturing factory. At the construction site, the project team creatively designed high-precision flexible structural systems and new modular connection node technologies, achieving “30-minute module installation” and “3-day completion of one floor.” As a result, Phase I of the project shortened the construction cycle by nearly 60% compared to traditional methods.
In terms of intelligence, China State Construction Hong Kong independently developed the C-SMART engineering management digital platform, achieving comprehensive smart and refined management of personnel, materials, progress, and processes. Materials can be tracked “with one click” from factory to site. The project adopts MiC (Modular Integrated Construction), supporting 100% disassembly and reuse, effectively reducing construction waste, providing a demonstration for exploring circular building systems, practicing green construction concepts, and assisting in achieving carbon neutrality goals.
