13. Information Delivery Manual (IDM)
To make BIM effective, information needs to be:]
- made available when it is needed and
- to a satisfactory quality.
This can be achieved by using an Information Delivery Manual, that identifies the various construction processes, and the information required at each stage. ISO 29481-1 specifies a methodology for the format of the IDM.
IDM also forms one part of the BuildingSMART interoperability model; the other two parts being the Data Dictionary (mapping alternative terms for common elements) and IFC (see above). Note that this is beyond the scope of Level 2 requirements.
14. Information Manager
The CIC BIM Protocol (see above) refers to and provides for the appointment of an ‘Information Manager’ by the employer. This is, in essence, a project manager, who is responsible for managing the delivery of the asset using BIM procedures and methods. This is expected to form part of a wider set of duties under an existing appointment and is likely to be performed either by the Design Lead or the Project Lead.
