Sustainability Report 2021/22

Value Created for Supply Chain 42 Sun Hung Kai Properties Limited • Sustainability Report 2021/22 Case Study – Leveraging Technology to Add Value in Construction We work with our business partners to utilize innovative technology in construction, to foster sustainable practices, enhance safety and efficiency, and minimize our impact on the environment and the community. Adoption of Robotic Technology at Construction Sites We proactively deploy innovative technology in construction sites to ensure quality, enhance efficiency and reduce waste. An AI-based glass-inspection robot was introduced to inspect facade glass in glass fabrication plants before shipping to sites, and after installation to replace traditional human inspections and minimize errors in quality checking. By leveraging the built-in laser illuminated multi-surface scanning system and AI-based human perception defect prediction engine with fuse visual and geometric features, the robot conducts flaw-checking of glass panes and detects line defects width greater than 0.1 mm and mini dots with defect size greater than 0.5mm. In addition, it provides digital records between glass-fabrication plants and respective sites for traceability, greatly enhancing our monitoring process on building quality. To prevent hazards caused by human error and to enhance overall construction safety, we seek opportunities to replace high-risk manual operations with innovative technology. Our Sai Sha project, for example, is considering using robots for painting and plastering. Adoption of the ‘Rotational Bridge Launching Construction’ in Hong Kong SHKP successfully accomplished the first-ever rotational bridge launching construction at The YOHO Hub, applying such methods to build two bridges that link The YOHO Hub to Yuen Long Station on the Tuen Ma Line. To begin with, we set up a steel turntable system on site that connects the assembled bridge structures to the system. Following that, we rotated the bridge structures by 180 degrees horizontally before they were finally lowered onto their permanent bearing supports using vertical strand jack systems. The first-ever rotational bridge launching construction at The YOHO Hub is expected to be operated in 2023 Meticulous planning and preparation are required for these innovative techniques. To ensure that we could carry out the task, we gathered around 300 experienced staff, consultants and specialist subcontractors to plan the construction, and invited bridge and heavy-lifting experts from overseas to carry out independent reviews. In addition, we adopted Building Information Modelling (BIM) at the preliminary design stage to simulate all possible worst-case scenarios so as to better prepare ourselves for any challenges that might arise, ensuring the construction was safe and efficient. For example, the entire rotational launching system was designed to withstand hurricane-level wind forces even during the course of the rotation. Despite a higher cost, the new technique enabled greater efficiency by shortening the bridge construction time by nearly 60%. We were able to complete the two bridges at The YOHO Hub in just four midnights, thereby greatly minimizing the adverse impacts on the surrounding facilities and residents. With safety as our top priority, this innovative method enabled all steel and facade erectors to work at much lower elevations. Simultaneously, the risks of disturbing the railway operations and public-road users were kept to a minimum. The two bridges unobtrusively appeared in the Yuen Long community without any unnecessary nuisances and in the safest manner. For more details, please watch the video here .
