TecHNoLoGy Figure 4: A BIM model is rich in information but should not contain too much too soon Work by most major software developers is progressing, to help the exchange of data between applications, through a common format. It is hoped that soon the users won’t have to be concerned with the technicalities involved. It just needs to work! Third, the model has to ‘make sense’ to the party receiving it. In Figure 5, the architect may have built the external walls in the model from a series of components classified as ‘panels’, while the engineer’s software may only understand components classified as ‘walls’. Work is progressing, by industry and professional organisations, to define/agree common classifications. These can then be built into the relevant applications and be embedded in project templates, processes and protocols. Again, this should help to avoid having to deal with this individually. A great deal of information can be added To avoid frustration the team should start to a model. It can then be sent to another the project by agreeing what information In the meantime and to avoid frustration, party and they can access the information. will be added to the model and when.
