In June 2020, WorldSteel Group implemented The Sun Tower project with the production and assembly category of Kingpost for this project. The categories were completed and handed over by WorldSteel Group on October 21, 2020.
In order to improve investment efficiency and serve the needs of users, high-rise buildings with many basements have been built more and more in big cities. With the narrow construction space, the technology of building basement by Top-down method is becoming more and more popular. Playing the “backbone” method in the Top-down method is kingpost system made of composite steel or cast steel. This is a column system that temporarily supports the basement floors and some body floors during construction, when the main load-bearing column system of the construction has not been constructed or has no bearing capacity. In the work of setting up a construction method for the basement, the design of kingpost at the location associated with the bored pile is extremely important, deciding the stability, safety of the work, construction cost and construction of kingpost plan.
The Sun Tower is a very large-scale construction, the project has an area of about 0.6 hectares, including 5 basements and 55 floors. The total construction floor area is more than 106,000m², located at Ton Duc Thang Street, Ben Nghe Ward, District 1, HCMC. The project is located in the Ba Son urban area and is the most beautiful location of this urban area, connected to the Ba Son station of metro line No. 1. participating in this project, Worldsteel Group undertakes the production and connection category of kingpost with the steel structure volume up to 550 tons.
