The project is located at Gaoming District, Foshan City, Guangdong Province, and covers a total area of 6, 961.8 m2. Centering on the development theme of “energy + technology towards carbon neutrality”, the project creates an integrated station for hydrogen production from natural gas and in-station hydrogen refueling. Among them, the hydrogen production module adopts the first set of skid-mounted natural gas-hydrogen production facility in China with independent intellectual property rights. It is designed to construct a comprehensive energy supply station integrating natural gas hydrogen production, photovoltaic power generation coupled with water electrolysis hydrogen production, hydrogen refueling, gas feeding and other functions.
In December 2021, the natural gas-hydrogen production facility successfully produced highly pure hydrogen, with the highest hydrogen purity up to 99.999% worldwide. In August 2022, the Phase I of the project was officially put into operation. It has filled the gap in the domestic industry and been reported with a feature story by CCTV news channel.

Located in Foshan City, Guangdong Province, the project comprises a pipeline as long as about 23 km, the expansion of Xiqiao pressure-regulating station, and the construction of Jinben pressure-regulating station. The total investment of this bid section is about CNY 525.16 million yuan. The project will be connected with the existing high-pressure pipe network system in Foshan, so as to construct a north-south gas transmission channel and to connect the downstream urban medium-pressure transmission and distribution system. The project will meet the gas demand from various urban gas users in this region, strengthen the stability and security of gas supply, and facilitate the development in low-carbon energy.

Located in Longgang District of Shenzhen City, the project covers 8 sub-districts, 44 sub-projects, 114,000 households and a total investment of about CNY 795.552 million yuan. The project, upon its completion, has laid a solid foundation for Longgang District to achieve the goal of eliminating gas cylinders by the end of 2023.

Intelligent transportation control platform of Foshan 1st Ring Expressway is a traffic signal control platform developed for local traffic signal timing optimization centers based on the regional coordination control theory. By optimizing traffic control and intelligent operation and maintenance management, it is to improve traffic efficiency, ensure traffic safety and establish a service guarantee system for citizens' travel and urban traffic management. The platform mainly forms optimization schemes for single point, main line and regional traffic signal control through the analysis and calculation of the urban traffic network on the whole time, whole area and whole amount, and makes real-time evaluation and feedback on the optimization effect of the schemes, forming optimization suggestions for traffic control to ensure the optimal effect of regional traffic control. In addition, with intelligent operation and maintenance management and other functions, it can provide real combat business linkage for traffic management business scenarios, such as real-time supervision of key vehicles, optimization of traffic operation management, intelligent management and control of events and alarms, monitoring and analysis of equipment faults and abnormalities.

Zhuhai Modern tram is the first tramway using ground-level power supply system in China, which has zero emission during operation. The first phase project of Zhuhai modern tram line 1, designed by STEC, stretches 8.7 kilometers. All 14 stations are above the ground, and the line has one tram base. The modern trams are 100% low-floor, with steel wheel and steel rail. The whole line uses catenary-free ground-level power supply system. STEC also adopts environmental-friendly lighting system, which gradually adjust light to become brighter when the tram reaches the station, and the lighting intensity differs on holidays and working days. In addition, in order to make full use of the tram as a major public transport, STEC offers a series of value-added services for the city. That includes 10 shuttle buses’ routes and transportation plan which can serve more than 110,000 people, as the tram network is not fully developed and there are only very limited connections with existing public transports in the first phase project of Zhuhai Modern tram line 1. The first phase of the tram involve dedicated lane rights, before the traffic flow matures and early stage transportation stabilizes, some lanes will be free, while other lanes are crowded. STEC analyzed the tram lane’s characteristics, accessible time and numbers, and then set limited conditions for cars to share the tramway. That means, trams use the first-phase tramway exclusively, but at the intersections, some of the roads are shared. On the basis of intersection traffic organizing principle, STEC offered signal control strategies and intersection signal control solutions to ensure the signal control are embedded in the design. Our study on the tram is gradually expanded to more routes and functions. We also drafted guidelines to help trams become the major transport mode in the city.

Guangzhou Baiyun International Airport, a large-scale civil airport in Guangdong Provincial Capital Guangzhou, is one of the three largest airports in China. As one of the earliest companies taking part in the construction of the new Baiyun Airport, STEC has constructed many projects, including overhead bridges on airport’s highway, earthwork and drainage work in the flight area, China’s first taxibridge, tarmac, parking lot, and the third runway, witnessing the Baiyun Airport turning into one of three largest airports in China. Amongst which the flight area bridge project was honored the Tien-yow Jeme Civil Engineering Prize, National Green Building Innovation Award, and Shanghai Infrastructure Golden Prize. After more than ten years’ efforts, we’ve constructed several star projects at the airport, which largely improved the airport’s overall management abilities. The third runway project for the airport’s expansion, is built to the highest global standard, meeting 4F class aircraft usage specifications and able to accommodate the largest passenger aircraft model A380. The third runway was put into use in February, 2015, marking Guangzhou Baiyun International Airport the third domestic airport to have three runways, after Beijing and Shanghai.
