As the single satellite hall with the largest throughput in the world, the T3B Terminal will achieve the annual passenger throughput of 35 million and has been widely concerned by various sectors of society since the establishment of the project, with significant influence from all parties. During the construction period, the original Jiangbei Airport T3A was in normal operation, and measures must be taken on site around personnel education, lighting control, communication and electromagnetic signals, and height limit management control to ensure the normal operation and safety of the airport. The goal of the project construction is to build a world-class "four-type airport" with the concept of "safe, green, smart and humanistic" and create a national three-star green building with advanced design concept and various applications of "four new" technologies. The coordination and cooperation for constructions of curtain wall, steel structure, flight area platform engineering, APM rapid transit system, baggage system equipment installation engineering, etc. is difficult, with many professional subcontracting.

The project is located in the urban functional core area of Longsheng Zone, Longxing New Town in Liangjiang New Area, which covers an area of 210 mu, with a total investment of about RMB 4.5bn and a total construction area of about 391,000 square meters, including 249,000 square meters above the ground and 142,000 square meters underground. In Phase I of the project, we plan to implement 1,500 hospital beds and more than 3,700 parking spaces. The project is expected to complete construction by the end of September 2025 and be put into use by the end of the same year. Combining the concept of "flowing water along the canyon flourishes two rivers", the hospital extracts the charm of the natural scenery in the mountain city, takes horizontal lines as the main structural elements, with the integrated design of glimmer and sunshade, and features in the horizontally extended building groups that are like stratiform clouds. The project closely follows the requirement of national dual carbon targets and configures a free ecology, aiming to achieve natural lighting and ventilation for the large-scale medical complex by interpenetration of indoor and outdoor spaces with flexibility and variety; and by utilizing various measures such as power generation technology of vertical shading, active and passive energy saving and carbon reduction are realized.

The PPP Project of Tuanjiehu Big Data Intelligent Industrial Park locates in the Tuanjiehu Big Data Industrial Park, Shuangfu Street, Jiangjin District, Chongqing City. Construction scale of the project: buildings for production services include intelligent manufacturing bases A and B, Waterfront Convention Center, R&D and innovation center areas A and B, etc., with a total area of about 366,200 square meters and a construction area of about 600,000 square meters. Public service facilities include Xiangtang Elementary School, which covers a total area of about 52 mu and a construction area of about 26,000 square meters. Infrastructure supporting facilities include 6 new-built supporting roads, Project of Tuanjie Lake Wetland Park Phase II Project, information system of the smart park, etc.

Ground penetrating radar (GPR) is an efficient and high-resolution shallow geophysical exploration method. In practical exploration, GPR emits and receives electromagnetic wave signals to image the signal in the instrument, expressing the influence of the medium in the propagation path on the propagation signal. The high-resolution radar 1.0 developed by China Construction Eighth Bureau incorporates efficient underground pipeline detection technology based on the BMS (Background Matrix Subtraction) algorithm and 3DVS (3D Velocity Spectrum) algorithm. This device can directly obtain the position, burial depth, and direction of underground pipelines through ground scanning, thereby shortening the construction period of infrastructure projects, avoiding pipeline excavation accidents, and achieving three-dimensional rapid modeling of pipelines. Compared with traditional detection technologies, the developed technology has the characteristics of higher efficiency and accuracy. The buried depth test error is 1.6%, and the on-site detection error is less than 7.5%.
