“Building Information Modelling (BIM) is a collaborative way of working, underpinned by the digital technologies which unlock more efficient methods of designing, creating and maintaining our assets. BIM embeds key product and asset data and a 3 dimensional computer model that can be used for effective management of information throughout a project lifecycle – from earliest concept through to operation. It has been described as a gamechanging ICT and cultural process for the construction sector. A number of countries globally are starting to realise the opportunities it brings and are now investing in developing their own capability. BIM processes are ‘mainstream’ to both new buildings/infrastructure and have further potential in ‘retrofit’ and ‘refurbishment’ projects when complementary workflows such as laser scanning and rapid energy analysis are employed.” (HM Government, 2012)
