HKIE-CIHT Joint Technical Seminar - Shaping Future Transport Planning: Insights from Travel Characteristics Survey

PolyU CEE was proud to support the technical seminar, “Shaping Future Transport Planning: Insights from Travel Characteristics Survey”, on 16 April 2026 which was jointly organized by the Chartered Institute of Highways and Transportation (CIHT) Hong Kong and The Hong Kong Institution of Engineers (Logistics & Transportation Division) (HKIE-LTD). We were honoured to welcome Ir Stephen Lee, Chief Engineer of the Transport Department, as our speaker, who provided a masterclass in bridging classroom theory with real-world practical application, offering our students and academic community a fascinating perspective on the shifting travel behaviours in Hong Kong. The seminar explored Travel Characteristics Survey (TCS) methodologies, a goldmine for smart mobility research. Key discussions focused on demographic shifts, such as population decentralization to the New Territories and the notable rise in household car ownership. The session also highlighted the transition toward Activity-based Travel Demand Model, an advanced strategic modelling technique that effectively captures modern trends like telecommuting and flexible scheduling. With over 140 attendees, including students, academic researchers, and young engineering professionals, the event underscored our collective drive to utilise comprehensive travel statistics to guide future policies, enhance transit networks, and optimise major infrastructure planning. CEE remains committed to facilitating the knowledge exchanges and bridging the gap between academia, policymakers, and industry practitioners. We extend our heartfelt gratitude to Ir Stephen Lee and all the participants. Stay tuned for more opportunities to connect your studies and research with the technological advancements shaping our city!   

PolyU ASCE Student Chapter Secures First Prize in 2026 Greater China ASCE Student Symposium Paper Competition

We are proud to announce that the PolyU ASCE Student Chapter has been awarded the First Prize in the 2026 Greater China ASCE Student Symposium Paper Competition. Under the mentorship of Prof. Kai Zhou, Assistant Professor of CEE, CEE undergraduate students Mr Zixuan Xu, Mr Naicheng Chen, Mr Chun Ki Liu, and Mr Hongjian Li brought honour to the Department and the University through their exceptional performance. Hosted by Zhejiang University during 10 - 12 April 2026, the Symposium featured various activities including Sustainable Solutions Competition, Technical Visit and a Paper Competition themed “Engineering the Public Welfare: How Civil Engineers Engage and Advance Communities Through Ethical Infrastructure Design in accordance with the ASCE Code of Ethics”.  The award-winning paper, titled “Beyond the Technical Optimum: Advancing Spatial Justice Through Ethical Infrastructure Design and Inclusive Policy”, examines how the ASCE Code of Ethics can benefit civil engineering to serve community effectively, bringing out an important alert that successful infrastructure design needs the community’s voice and support from its start. We extend our heartfelt congratulations to the PolyU ASCE Student Chapter Team for their dedication and research excellence. We look forward to their continued success in future competitions and contributions to the professional arenas.

Prof. Shu-Chien Hsu Secures Innovation and Technology Fund

Congratulations to Prof. Shu-Chien Hsu, Associate Professor of CEE, for securing HK$800,000 from the Innovation and Technology Fund (ITF) under the Innovation and Technology Support Programme (ITSP), administered by the Innovation and Technology Commission (ITC) of the HKSAR Government. In response to the pressing challenges of managing incineration residues (IBA/IFA) and construction waste in Hong Kong, Prof. Hsu’s research project, titled “From Waste to Shield: High-Value Utilization of Incineration Ash and C&D Waste in Sustainable Radiation-Shielding Concrete”, proposes an innovative "detoxification-to-valorization" strategy through geopolymer-based stabilization and functional activation. The research aims to effectively immobilize hazardous heavy metals while leveraging the naturally occurring high-atomic-number elements (such as Pb, Fe, and Ni) within the waste as functional components for radiation shielding. By developing a sustainable X-ray shielding recycled concrete for medical infrastructure, this study seeks to pioneer a full-volume, high-value recycling solution that supports Hong Kong’s transition toward green construction and a circular economy. The ITF is designed to enhance the added value, productivity, and competitiveness of Hong Kong’s economic activities. Through the ITF-ITSP, the Government seeks to support applied research and development (R&D) projects undertaken by R&D Centres or designated local public research institutes in collaboration with companies. We extend our heartfelt congratulations to Prof. Hsu. His innovative research in transforming waste into sustainable construction materials will promote sustainability and help achieve carbon neutrality goals in the construction sector.

CEE Departmental Visit – China Holiness Church Living Spirit College (27 March)

A group of students from China Holiness Church Living Spirit College visited CEE on 27 March 2026 (Friday). The visit began with an interactive Q&A quiz hosted by Prof. Andy Y.F. Leung, Associate Head and Associate Professor of CEE, which provided students with an engaging overview of the recent developments in civil and environmental engineering. Prof. Leung also shared information about admission procedures and career prospects for BEng (Hons) in Civil Engineering and BEng (Hons) in Environmental Engineering and Sustainable Development programmes to the group. The highlight of the day was the Tower Challenge: Engineering with Straws, Tape and Imagination. Using a limited supply of straws and tape, students utilized their creativity and basic engineering principles to construct freestanding towers. The winning team achieved a tower height of 97 cm. The group also had the opportunity to visit the University Gallery, where they were about to learn different aspects of PolyU, including its history and impactful research. Alongside a collection of insightful facts, students gained a deeper understanding of PolyU’s rich history of pursuing excellence as a leading, innovative, and world-class university. We express our gratitude to all students and teachers for their enthusiastic participation. We look forward to welcoming more young talent to explore the world of civil engineering with us!
