Case Study – Creating Innovations to Support Sustainable Construction The Group embraces and actively integrates the use of innovative technology into traditional construction practices in collaboration with its business partners, aiming to drive low-carbon and sustainable transition in the value chain. Our integrated commercial project at 98 How Ming Street in Kwun Tong featuring an array of new technological applications has earned industry recognition, for example, the Gold Award in the Innovative Safety Initiative Award 2020 (Health & Welfare). The innovations adopted at the site are shown as below: Enhance Construction Quality and Efficiency With the support of 5G network and cutting-edge technology, physical and digital information can be efficiently interpreted, ultimately improving resource efficiency, workflows and precision. For instance, the construction site uses BIM to present real-time, highly detailed construction models for engineers to review the design and layout, materials and craftsmanship. With Mixed Reality (MR), the digital information is superimposed on the physical environment, delivering a seamless translation from abstract ideas into physical objects. Also, electrical and mechanical modular integrated construction methods are introduced to boost overall construction quality and reduce wastage. Minimize Environmental Impacts During Construction Process It was the first-ever exothermic welding being used to replace traditional electric arc welding in Hong Kong, helping to curb the emission of waste gases and fumes during the welding process. Also, a groundwater circulation system was built at the construction site to enable the use of groundwater instead of fresh water, and an excavation and lateral support (ELS) system was set up to substantially reduce the consumption of steel. In addition, electric vehicles are used in the project to reduce emissions. Improve Safety Performance on Construction Sites SmartWorks system, which was developed by our subsidiary SmarTone, was deployed at the site to enhance the occupational safety and health of our construction workers. The system is integrated with programmes such as Smart Helmet, Smart Health station, large machine Danger Radar, access control and environment station. The Smart Helmet which is equipped with sensors and GPS trackers will send out a real time alert to site supervisors if a construction worker falls down. Also, the transport machinery has laser lights installed to reduce the risk of workers entering the operating zone of the machinery by accident. • The Use of MR technology at the construction site Value Created for Supply Chain Sun Hung Kai Properties Limited • Sustainability Report 2020/21 37
