Hong Kong West Drainage Tunnel (HKWDT) Was Honoured with the 12th Tien-yow Jeme Civil Engineering Prize Organised by the China Civil Engineering Society
The Tien-yow Jeme Award is the top honour for civil engineering and construction in China. The awards are given to projects featuring distinction in innovation and technical advancement.
Hong Kong West Drainage Tunnel
HKWDTis the biggest floodprevention project ever implemented in Hong Kong. It comprises 11km long main tunnel from Tai Hang to Cyberport, with an internal diameter ranging from 6.25m to 7.25m. It has 8km of adits and 34 intakes to intercept upland flows from existing streams and drainage system at Mid-Levels. The collected runoff will be discharged directly into the sea, significantly alleviating the flooding risk in Central and Western District as well as Wanchai District.
As the project consultant, Arup carried out the design, pre-qualification, tender and construction supervision for the project. We brought in a number of innovative solutions that significantly reduced construction time and cost. HKWDT sets numerous records for the city - it is the first one in Hong Kong to carry out TBM excavation and adit blasting concurrently, and pioneered the extensive use of raise boring method for dropshaft excavation. These technical breakthroughs not only facilitated the project, but also minimised the impact on residents, traffic and the environment during construction and created a safer working environment.
