On May 15, it was learned from the Project Management Department of the T2 Terminal Project (North Section) of the Kunming Changshui International Airport Expansion and Renovation Project of China Construction Third Engineering Bureau Group Co., Ltd. that, following the full topping-out of the concrete structure of Concourse C of Terminal T2, the roof steel structure project has also achieved full topping-out.

In recent days, the construction site of the North Section of Terminal T2 of the Changshui Airport Expansion and Renovation Project has been bustling with activity: tower crane jibs swing, various cranes assemble steel structures, skilled workers weld steel beams on mobile elevating work platforms, machinery roars and workers are busy on site, with everyone seizing the golden period for construction.

Terminal T2 is the core project of the Kunming Changshui International Airport Expansion and Renovation Project, with a total floor area of 730,000 square meters. It comprises one main terminal building and four concourses, and is divided into two construction sections, the North Section and the South Section. Construction started in September 2024 and is scheduled for completion in 2029.

The North Section project mainly includes three parts: the terminal core area, Concourse A and Concourse C, with a floor area of about 507,000 square meters. The terminal core area has two basement levels and four above-ground levels, totaling six floors; the concourses have one basement level and three above-ground levels, totaling four floors. Because the project involves the GTC area of the comprehensive transportation hub, it needs to interface with the Chongqing-Kunming High-Speed Railway, Metro Lines 6 and 9, and highway approach bridges, making the construction process more complex.

Since the start of construction, the Project Management Department of China Construction Third Engineering Bureau has attached great importance to quality management, focusing precisely on the three core areas of pile foundations, concrete structures and steel structures, strictly implementing the acceptance systems of "construction according to mock-ups" and "consistency between the actual structure and mock-ups," and fully promoting 3D scanning technology and the "sample-leading" mechanism to ensure construction precision.

The bureau, for the first time in Yunnan, adopted its self-developed remote-driving intelligent centralized-control digital tower crane technology for construction, improving construction efficiency and enhancing safety, and achieving the "double zero" goal of zero accidents and zero casualties. At the same time, intelligent construction methods such as a digital pile foundation construction system were also used during project construction to ensure that construction quality meets the requirements for excellence awards, truly realizing digital and intelligent construction.

"Since the beginning of this year, about 500 people, including management personnel and workers, have been involved in construction on the site every day. The concrete structure of the fastest-progressing Concourse C achieved full topping-out at the end of January this year, and secondary structure construction is underway. During the May Day holiday, everyone stayed at their posts and went all out to ensure that the roof steel structure of Concourse C achieved full topping-out in recent days," Yuan Song, chief engineer of the Civil Engineering Department of the Project Management Department of the T2 Terminal (North Section) of the Changshui Airport Expansion and Renovation Project of China Construction Third Engineering Bureau, told reporters. "With the support of intelligent construction technologies, everyone is working hard to accelerate project construction. The concrete structure of the core area has been completed about 90 percent overall. We will ensure that the main structure of Terminal T2 (North Section) is fully topped out on schedule, complete the large-area lifting of the roof space frame by the end of the year, and make full preparations for entering the decoration and mechanical and electrical installation stages."
