This chapter considers Building Information Modelling (BIM) as a quality system and discusses its current state of development in the UK. BIM is treated as a technology-enabled quality system for improving the competitiveness of all organisations operating within the extended construction and property sectors that relates to the whole life of all built assets. The UK Government's 'BIM mandate' was for 'collaborative 3D BIM'. '4D BIM' involves linking a time schedule to a 3D model to improve the time planning and control of construction activities. 5D BIM caters for estimating, cost management and procurement. BIM for Sustainability allows information such as energy use, resource efficiency and other aspects of sustainability to be better analysed, managed and understood. 7D BIM tackles the management of facilities or assets. A number of standard protocols for the BIM process had been developed in the United States. Since 2011 the UK Government has commissioned 'standardised solutions' for working in BIM.
