iLab had the great pleasure to receive 4 groups of 80 visitors from HKUEAA (HKU Engineering Alumni Association) Homecoming Walk on 15 October 2023. They included Director of Government Electrical and Mechanical Services Department (EMSD), CEO of CLP, and many senior figures from MTR and other organisations, who mingled well with younger generation and even children. That gave a good exposure to both the young and senior generations about the architecture, engineering, and construction (AEC) industry and the innovations and technologies at the frontier.
