• 採用BIM技術：在設計和建造階段採用了建築信息模擬（BIM） 技術，提升工程質素及效率。約70%須更換的喉管段落位於 地底擠迫的地下設施和地基結構之間。工程團隊採用探地雷達 核實地底結構和設施的位置，成功使用BIM模型進行碰撞分析 並制訂出可使用水管推頂法的隧道最佳深度。在4D和5D BIM 模擬的幫助下，得以準確估算改變建造階段造成的時間和成本 影響。 • Leveraging BIM Technology: Throughout the design and construction stage, Building Information Modelling (BIM) technology was adopted to enhance the project quality and efficiency. About 70% of the replacement sections were located underground with congested utilities and foundation structures. The project team adopted ground penetrating radar to verify the locations of the underground structures and utilities. By using the BIM model, clash detection was successfully performed and a feasible alignment for the pipe-jacked tunnel at an optimal depth was able to be identified. With the help of 4D and 5D BIM simulation, the time and cost implications of alternating the construction phases could be accurately assessed. 使用BIM模型進行碰撞分析，確定使用水管推頂法具可行性的隧道最佳深度——7米處碰撞（紅圈）12米處可行（綠圈）。 The use of BIM technology enables clash detection and identification of feasible alignment for the pipe-jacked tunnel at an optimal depth – clashed at 7m (red circle) and flexibility at 12m (green circle) is detected. 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 61 Scale up 升 級 開 拓
