ACKNOWLEDGEMENT _________________________________________________________ 143 FEEDBACK FORM _____________________________________________________________ 144 3 Foreword In 2014, the Construction Industry Council (CIC), in collaboration with around 20 Foreword stakeholder organisations of the construction industry, published a report named “Roadmap for the Strategic Implementation of Building Information Modelling (BIM) in Hong Kong’s Construction Industry” (hereinafter referred to as the “BIM Roadmap”) with an aim to establish a blueprint for the promotion and adoption of BIM in Hong Kong’s Construction Industry. The BIM Roadmap suggested seventeen initiatives in nine areas with three imminent actions. Establishment of a local BIM standards is one of the recommended imminent actions aiming to set out a common platform and language for Hong Kong’s BIM practitioners. The CIC’s BIM Standards will be implemented in stages. The scope of this Phase One Standards is as follows:- a. How to prepare an architectural model from concept, feasibility and planning stage to as-built stage; b. How to prepare a structural model from concept, feasibility and planning stage to as-built stage; c. How to prepare a mechanical, electrical and plumbing (MEP) model from concept, feasibility and planning stage to preliminary and scheme design stage. The Phase One Standards is intended to be simple and straightforward such that it can be easily mastered by layman and new BIM practitioners. Upon receiving feedback from the practitioners subsequent to the issuance of this Phase One Standards, we will review the necessity for preparing further phase(s) of the standards. This Standards was prepared with reference to current BIM standards of the Hong Kong Housing Authority (HKHA), MTR Corporation Limited (MTRC) and Hong Kong Institute of Building Information Modelling (HKIBIM). The Standards was also prepared with reference to the local practice whilst trying to bridge regional and international standards. 4 On behalf of the CIC, I would like to thank everyone who has contributed to the making of this Standards, in particular to the members of the Task Group on Establishment of Foreword Industry Standard.
