Building easily outlast their inhabitants. Buildings last forever while civilizations rise and fall. Edifices remain as testaments of cultures and history, other than dwelling for humans. It also represents the advanced level of technology and human society. Building Information Modelling (BIM) in today's building industry is believed as a holistic evolution. It started with software breakthrough. After a while the practitioners realized a proper BIM implementation specification with a focus on the technology, data, process, legal, people and culture is needed to assist BIM users to achieve a standardized adoption procedure and better results. Scholars furthermore argue that it is not necessary to adopt full BIM, instead, a lean BIM concept should be considered.This book introduced a benchmark for BIM users to assess their current BIM capability, strength and weakness in project, organization and industry level. Hence, the most informed decision and strategic plan can be made. Two vital elements of this framework are: a comprehensive set of decision making criteria and a reasonable priority system - where the weightage assigned to each criteria should align with the company's objective and vision. The proposed concept can be applied regardless of project types, regions, regulations, clients' requirements etc. while specific information could definitely improve the accuracy of the framework and achieve a much higher level of BIM.This book is for high end BIM users and guide their daily BIM tasks. Those users include but are not limited to: BIM managers, regional BIM directors, BIM strategist, project managers from all parties including designer, contractor, QS, developers as well as the facility management group. This book is also suitable for BIM modelers, coordinators, designers, builders and other individuals who are engaged in a BIM based project and would like to go further. This book has demonstrated the proposed benchmark, its unique development method, application in real projects and lesson learned, take away points for reader's better understanding.
