ABSTRACT
Following on from the introduction to BIM in Chapter 6, the purpose of the present chapter is to map out current BIM usage patterns, mainly in the UK, but also including reference to France, Germany and the USA. Two principal sources of information are used: recently published surveys and a number of case studies. The surveys provide an idea of the level of uptake amongst the different industry players in each of the geographical areas. They also indicate how current users view BIM and the benefits they are, or claim to be, deriving from its use. However, for the purposes of this book, it is more important to explore the attitudes of the individual users and their firms, the methods being used on projects and the sorts of effects that are being experienced by the users. So the larger part of this chapter is given over to a series of short case studies that explore those aspects of real BIM today.
