              「建築信息模擬」技術的最新推行情況                                Update on BIM implementation
              「建築信息模擬」技術有利匯聚各方，合力以虛擬模                          BIM (Building Information Modelling) enables multiple
            式共同設計、建造和營運一座建築物。這項技術優                             parties to collaboratively design, construct and operate
            點甚多，例如：節省成本和資源、提高效率、改善                             a  building  virtually.  BIM  brings  benefits  such  as  cost

            件式建築，以及取得更高質量的成果。長遠而言，                             communications  and coordination, more  opportunities

            之前達到這個目標。                                          benefits in mind, the HA aims to implement BIM in the

            年內我們繼續更新房委會的「建築信息模擬」標準和                            development projects, and expects to have achieved this
            模型指引，製作新範本，支援不同的工程項目，並                             by the end of 2021.
