The Construction Industry’s Digital Transformation

The Construction Industry's Digital Transformation 上周出爐的《財政預算案》提到將推動工程監督系統數碼化,提升工務工程項目監管水準和效率。工程業界坦言,早年行內已有人嘗試將工程資料數碼化,惟監督效益跟業界習慣有異而被捨棄。隨著建築信息模擬技術(BIM)應用愈趨廣泛,有科技公司覷準商機,設計監督系統予工程界使用,預料未來一年生意翻倍,行內亦將有更多競爭。但有業界指,監督樓宇建築程序繁複,前線人員未必掌握使用,預計新系統難以在短期內全面引用。 (記者李卓穎 林紫晴)...
