The document discusses principles for defining information requirements for building information modeling (BIM) in the UK. It proposes establishing a central database of object definitions to be used by construction professionals, information providers, and software providers. The database would help enhance government websites and be one of the stepping stones to achieving level-3 BIM in the UK. Mock-ups of a potential website and Excel data are presented as examples. The goals are to define information needed at each stage, avoid complexity, and establish open data structures that can make the UK a leader internationally.
