The development and application of steel structure design and construction technology in Hong Kong construction

In recent years, with the continuous expansion of urban construction and advancements in architectural structural technology, the application of steel structure design and construction technology in urban construction has become increasingly widespread. Steel structures, known for their lightweight, high strength, and versatility, are extensively used in industrial plants, large-span structures, high-rise buildings, multi-story residential buildings, structures with high dynamic and seismic requirements, shell structures, demountable structures, light-gauge steel structures, and composite structures combining steel and reinforced concrete.

Hong Kong Steel Structure Engineering On one hand, the lightweight nature of steel structures reduces the dead load of buildings, eases foundation loads, and saves construction time and costs. On the other hand, the high strength of steel structures provides stability and excellent seismic performance, making them suitable for complex and rapidly changing urban environments.

However, the application of steel structure design and construction technology also faces challenges and controversies. Firstly, the complexity and specialized requirements of steel structure design demand engineers and construction teams to possess high levels of professional knowledge and technological capabilities. Secondly, the fluctuating prices of steel materials can have an impact on project economics. Additionally, the corrosion protection and maintenance of steel structures require significant manpower and resources.

To overcome these challenges, various stakeholders in the industry actively promote the further development and application of steel structure design and construction technology.

Strengthening relevant professional education and training: Steel structure companies enhance the expertise and skills of engineers and construction personnel. By offering training courses, organizing academic conferences, and promoting industry-academia research collaborations, the overall technological level and innovation capacity of the industry are continuously improved.

Enhancing supervision and standard formulation: Industry organizations and government departments establish sound industry access systems and evaluation mechanisms to certify and supervise companies and individuals involved in steel structure design and construction. This ensures that steel structure design and construction comply with safety, quality, and environmental requirements, enhancing industry norms and credibility.

Promoting innovation and research in steel structure technology: Various stakeholders in the industry actively collaborate with research institutions and universities to conduct cutting-edge technology research. This includes innovations in steel structure data, connection technology, and construction processes, aiming to improve the performance and construction efficiency of steel structures.

CHEC GOLD Engineering utilizes Building Information Modeling (BIM) in its construction projects. Through digital technology, BIM facilitates accurate design modeling, simulation, and demonstration of the entire construction process, assisting engineering teams in making informed decisions. BIM combines multiple drawings and information to showcase the components used to construct buildings in the real world, providing relevant information during the construction phase. This enables more precise construction processes, low-risk design, minimizes waste, and facilitates communication among engineering teams.

By collaborating with Nida, structural design optimization is conducted using three-dimensional linear calculations to analyze steel structures, leading to a reduction in steel usage by approximately 15%.

Considering factors such as construction plans, equipment, and material selection, multiple possibilities are explored to meet client requirements while reducing construction costs and enhancing social benefits.

With the continuous advancement of technology and the development of the industry, the deep integration of steel structure technology with architecture, engineering, equipment manufacturing, and other fields provides effective solutions for urban bridges, subway stations, railway stations, and large-scale buildings. This promotes sustainable urban development and the construction of green buildings.

Due to the lightweight and versatility of steel structures, they create more spacious and open indoor spaces, adding aesthetic appeal and functionality to buildings. Additionally, the rapid installation and dismantling features of steel structures facilitate building renovation and expansion, enhancing the sustainability and adaptability of urban constructions. Steel structure construction technology is playing an increasingly important role in urban construction, providing sustainable, safe, and efficient building solutions for urban development.
