  After the briefing, the students participated in a guided tour of the construction site led by our resident engineers. During the tour, the engineers described the functions and construction methods of various tunnel internal structures and answered students’ questions.
  
  This visit provided a valuable experience for students preparing to enter the engineering profession, and we hope these future engineers will be well-equipped to meet various challenges.
  
  
  
• On 12 March 2025, students from Po Kok Secondary School studying Physics participated in the “T2 STEM Workshop” at the T2 Kai Tak Community Liaison Centre. The project team introduced the background of the T2 project, followed by an overview of the working principles of tunnel boring machines and the innovative technologies utilized in the project.
  
  At the end of the session, our resident engineer shared her experiences and explained the general duties of engineers, helping students gain a better understanding of the industry and consider pursuing a career in engineering.
  
  After the presentation, students explored the centre and engaged in immersive games. These activities allowed them to learn about tunnel internal structures, experience piloting a tunnel boring machine, and use drones for tunnel inspections, among other tasks. We hope this visit will broaden their horizons and enhance their knowledge of engineering.
  
  
  
• On 8 March 2025, the young members of Tung Wah Group of Hospitals Jockey Club Tai Kok Tsui Integrated Service Centre visited the T2 Kai Tak Community Liaison Centre. The project team began by giving a brief introduction to the project's background, construction methods, and the innovative technologies being used on-site. After the briefing, visitors were encouraged to explore the centre and enjoy interactive facilities such as the Tunnel Internal Structure Puzzle, the Interactive Wall showcasing many innovations of T2, Augmented Reality (AR) and Virtual Reality (VR) experience. These interactive games and displays not only added fun elements to the exhibition but also enabled both adults and children to gain a deeper understanding of engineering technology through interaction.
  
  
  
• On 13 January 2025, the councillors of the Legislative Council A4 Alliance visited the Trunk Road T2 and Cha Kwo Ling Tunnel project. The project team introduced the project background and progress at the Kai Tak Community Liaison Centre. The councillors then explored the centre to gain a better understanding of the innovative technologies used in the T2 project. Afterward, the councillors proceeded to the western ventilation building of the tunnel for an on-site inspection. Our project team presented the design concept of the west ventilation building, then they visited the electrical and mechanical installations and discussed the operation of the tunnel ventilation system and related technologies. This visit strengthened communication and collaboration between the project team and the council, resulting in significant benefits for both parties.
  
  
  
• About 100 students and teachers from Canossa Primary School participated in the "T2 STEM Workshop," which was held at the T2 Kai Tak Community Liaison Centre on 6 January 2025. The project team began with a brief overview of T2, including its background, construction methods, and the innovative technologies being used in the project. After the briefing, students freely explored the centre and engaged with interactive facilities, such as the immersive cave for tunnel touring, augmented reality (AR), mixed reality (MR) interactive games and other physical games and models. Through these interactive activities, the students deepened their understanding of the T2 project. We hope that the visit has enriched their engineering knowledge and provided valuable guidance for their future career planning.
  
  
  
• On 3 January 2025, the District Council members of Kowloon City, including the members of the Traffic and Transport Committee, visited the Trunk Road T2 and Cha Kwo Ling Tunnel project. At the Kai Tak Community Liaison Centre, the T2 project team introduced the project, covering its background, progress, and the traffic arrangements for the entrances and exits, among other relevant information. The council members also explored the Community Liaison Centre to better understand the innovative technologies applied in the project. Afterward, they proceeded to the West Ventilation Building of T2 for an on-site inspection. The T2 project team introduced the electrical and mechanical (E&M) facilities and advanced technologies implemented within the building. Throughout the visit, there was a deep exchange of ideas. The T2 team not only responded to the inquiries but also gathered many valuable suggestions from the council members. This visit significantly enhanced the communication and collaboration between the project team and the community, bringing considerable benefits to both sides.
