• Conducted receiving QA/QC inspections of MiC modules upon arrival to detect any transport-induced damage to internal fittings or structure

Assistant Resident Engineer (Civil) at AECOM Asia Company Limited (2024-02 – 2025-08)

WSD's Contract No. 1/WSD/19 - In-situ Reprovisioning of Sha Tin Water Treatment Works (South Works) – Water Treatment Works and Ancillary Facilities. This NEC4 ECC Option C contract with contract sum of HKD 4.5 billions included demolishing the aging infrastructure of South Works of STWTW and constructing 6 major treatment buildings within same footprint to expand daily treatment capacity to 550,000 m3, while maintaining current operations of the Hong Kong's largest water treatment facility without any disruption.

• Responsible for works supervision and daily administration for construction of treatment buildings supported by raft foundation. Conducted site supervision for rebar / waterstop installation, workmanship issues / defect identification, and testing.
• Reviewed Contractor's submissions, including structural and architectural design for water retaining structure, temporary works designs (e.g. Temporary Watermains and associated supports for water tightness test & ELS Design), method statements, material submissions, BEAM Plus submissions, BIM progress reports, etc.
• Monitored / reviewed programme submitted by the Contractor to ensure work progress.
• Liaised with WSD/STWTW for traffic arrangement / construction works within existing STWTW in operation.
• Monitored Safety, Health and Environmental (SH&E) performance and implementation of safety plan & safety cycle by the Contractor.

Graduate Engineer (Water) at AECOM Asia Company Limited (2022-06 – 2024-02)

• Designed replacement and rehabilitation works for fresh water mains with internal bitumen lining across New Territories East and West, improving water quality and system durability.
• Utilized ArcGIS software to map existing watermains distribution and strainer locations, providing critical data to inform design and construction planning.
• Contributed to the utility impact assessment with utilities detection surveys to evaluate the effects of proposed works on local utilities systems, ensuring minimal environmental disruption.
• Conducted tender assessments using a marking scheme, evaluating bids based on technical and financial criteria to select the most suitable contractors.
• Collaborated with multi-disciplinary teams to conduct traffic impact, geotechnical, and environmental assessments, ensuring comprehensive planning and risk management.
• Designed fresh and flushing watermains, including a short section of 2m sleeve pipe (i.e. twin DN600 fresh watermains and twin DN300 flushing watermains) crossing Tin Ying Road designed to be constructed by horizontal directional drilling (HDD), for a public housing development.
• Conducted tender assessments using a formula approach, systematically evaluating contractor bids based on technical merit and cost.
• Collaborated with multi-disciplinary project teams to resolve design clashes using BIM, delivering coordinated and constructible designs.
• Assisted in planning and executing the replacement and rehabilitation of aged water mains across Kowloon and New Territories East, enhancing water supply reliability and safety.
• Conducted site surveys and condition assessments to prioritize water mains for replacement, leveraging risk and performance data to inform decision-making.
• Contributed to the development of a technical proposal for the risk-based improvement of water mains in Kowloon and New Territories East.
• Researched and proposed cost-effective solutions for water main replacement, evaluating factors such as material selection and construction methods to optimize project budgets.
