Master information document index MIDI

Building information modelling (BIM) is a very broad term that describes the process of creating and managing digital information about a built asset.

In the UK, the Government Construction Strategy stated that the '...Government will require fully collaborative 3D BIM (with all project and asset information, documentation and data being electronic) as a minimum by 2016'. This represents a minimum requirement for Level 2 BIM on centrally-procured public projects.

PAS 1192-2:2013 Specification for information management for the capital/delivery phase of construction projects using building information modelling (now replaced by BS EN ISO 19650), sets out the requirements for Level 2 BIM in the capital/delivery phase of projects (PAS 1192-3 focusses on the operational phase).

PAS 1192-2 defines the master information document index (MIDI) as the:

'Index specifying a detailed list of the deliverables for a project; for model, sub models, documents and data also allocating responsibility to deliver and the programme for delivery of a project supply chain.'

However, there is no other reference to the master information document index, who produces it or when, and how it differs from the master information delivery plan (MIDP) which the PAS describes as the primary plan for the preparation of project information required by the employers information requirements, setting out programme, responsibility, protocols and procedures.

There may also be some overlap with the model production and delivery table (MPDT) defined in the CIC BIM protocol as, '...specifying the subject matter of each Model, the person who is to produce and deliver each Model (described in the table as “Model Originator”) at each Stage and the Level of Detail for each Model at each Stage.'

On 31 July 2015 BSI published a draft revised PAS 1192-2 for consultation. Reference to the master information document index was removed in this revision. See PAS 1192-2 consultation for more information.
