The seminar commenced with a welcome speech and speaker introduction by Prof. CHEN Qingyan, Director of the PolyU Academy for Interdisciplinary Research (PAIR). In his presentation, Prof. Cao stated that urban environment engineering seeks to apply system engineering to solve complex urban problems. He highlighted that interdisciplinary research that combines scientific and mathematical approaches is crucial for understanding the mechanisms and laws concerning the complex interactions between humans and the ecological environment. Prof. Cao emphasised that the modelling of urban pollution involves a mix of techniques, including remote sensing, big data, computational simulation, the Internet of Things, artificial intelligence, digital twins, etc. He gave various project examples to explain how different techniques can be used for scientific monitoring, fast prediction, assessment and regulation of urban pollution. To conclude, Prof. Cao pointed out that advancements in urban environment modelling and intelligent control can build the scientific foundation for sustainable urban development.

The lecture commenced with a welcome speech and speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation). In his presentation, Prof. Chen first gave a brief introduction to the United Nations’ 17 Sustainable Development Goals (SDGs) as well as the SDG monitoring practices in Mainland China. He pointed out that the Nation has adopted the high quality sustainable development concept, which emphasises harmonising the social, economic and environmental aspects in national development. Next, he elaborated on a pilot project that he led to measure Deqing County’s progress towards SDGs using geospatial and statistical information. The project was selected by the UN Department of Economic and Social Affairs as one of the first 16 good SDGs’ practices in 2020. After that, Prof. Chen shared that the achievement of sustainable development requires holistic and systematic research to build a digital governance system that can provide the basis for the scientific and orderly development of national territorial space. He also explained how territorial space sustainability studies can help unveil and analyse various patterns, such as the distributions of population, enterprises and public service facilities, and the relationships between them. To conclude, Prof. Chen introduced the national program on the development of the Realistic Geospatial Landscape Model (3dRGLm), which can generate digital description and representation of the real 3D geospatial spaces. This new geographic information system can support the Nation in achieving natural resources management and high quality sustainable development.
A question-and-answer session moderated by Prof. DING Xiaoli, Director of the Research Institute for Land and Space (RILS) and Prof. WENG Qihao, Associate Director of RILS, followed. The online and on-site audience engaged in a productive discussion with Prof. Chen.

The lecture commenced with a welcome speech by Prof. CHEN Qingyan, Director of PAIR, followed by a brief speaker introduction by Prof. Christopher CHAO, Vice President (Research and Innovation).
In his presentation, Prof. Brilakis first gave a brief introduction to digital twins (DT), pointing out that DT plays a central role in digital transformation. Next, he elaborated on the application of DT in the construction industry and explained how DT is involved in the planning, design, construction, maintenance and operation processes. He introduced research conducted at the University of Cambridge on inexpensive methods for generating object-oriented infrastructure geometry, detecting, and mapping visible defects on the resulting DT, automatically extracting defect spatial measurements, and sensor and sensor data modelling. Prof. Brilakis also provided examples of how these resulting DT are further exploited in design for manufacturing and assembly (DfMA), mixed-reality-enabled mobile inspection, and proactive asset protection from accidental damage. To conclude, Prof. Brilakis stated that DT, smart materials, data science, and automation & bobotics, constitute important digital assets for driving sustainability, and pointed out the future development directions in these areas.

In the lecture, Prof. Batty gave an overview of the development of the science of cities in the last 50 years. Drawing on the system approach and complex theory, he explained that urban science involves top-down and bottom-up thinking; it is a systematic, complex and evolving discipline built on knowledge in social physics, economics, transportation and numerous scientific methods that yield theories. He illustrated this with city morphology examples from the UK and the Greater Bay Areas (GBA) generated by large-scale computer models. At the end of the lecture, Prof. Batty described some challenges with fractal geometry, size and scaling, networks, and building models currently faced by the field, and he suggested the way forward for the discipline.

This project aims to study the exportation history of Hong Kong’s quality granite to the Pacific Rim and the construction history of those overseas projects using exported stones in the 19th and 20th century. The following five aspects are investigated:
The colonial government record in 1844 granite was shipped to mainland China. During 1850s and 1860s, granite blocks were exported to mainland China, New South Wales, San Francisco and Siam and used as building materials and paving slabs.
In 1852, the façade of Parrott Building in San Francisco was cladded with quality granite from Hong Kong. Twenty workers and two supervisors from Hong Kong boarded a cross-Pacific ship for the erection of this epoch-making building.
Between 1860 and 1870, granite was quarried in Kowloon, for the construction of the French Catholic Church in Canton. In 1890, the Gap Rock Lighthouse was built by a Hong Kong contractor using the granite from Hong Kong.
Between 1928 and 1933, quality granite was chosen in the projects of The Mausoleum in Nanjing, The Memorial Auditorium and the Memorial Cenotaph in Guangzhou in remembrance of Dr. SUN Yat-sen. These projects were designed by architect LU Yen-chih and constructed partly by contractors from Hong Kong.
