Changsha airport's Terminal 3 on target

The Terminal 3 project at Changsha International Airport is going smoothly and is expected to be completed on schedule by 2026, according to the builder.

Lyu Yongjin of China State Construction, who is in charge of the project, said the terminal has a total construction area of about 500,000 square meters, making it the largest single public building in Hunan province.

The terminal consists of a main hall and five concourses, with a radial layout in which the concourses resemble the five triangles of the Changsha Star, he said.

The project has 75 planned terminal aprons and is expected to be operational by 2026. Once completed, it will accommodate an annual passenger throughput of 40 million people, he said.

It will also become a modern integrated transport hub with the most transit options — two subway lines, one high-speed railway, one inter-city train and one maglev train — and the highest transfer efficiency in China, he added.

The smart construction site system operates efficiently on the site, with panoramic cameras automatically synthesizing panoramic monitoring feeds and daily time-lapse footage used for project review, he said.

The project deeply integrates several core technologies, such as green building, renewable energy use and smart operation and maintenance. The result will be a green, low-carbon airport terminal, he said.
