Below are two screenshots. One of some traditional drawing status notes of old. And next to it is ISO 19650 BIM status/suitability codes and descriptions (from the UK National Annex). I find some of the ISO suitability codes and processes a little confusing, particularly regarding work in progress. Any thoughts?
Work in progress
S0 - Initial Status - as I understand it this is only for internal use only, when editing your model/drawings, and should never appear on models/drawings shared with the rest of the design team. ISO 19650 explicitly states that information in the work in progress state/folder shouldn't be accessible to other task teams. But we often need to discuss work in progress with other team members so how are we meant to issue WIP information to other design team members if no one else has access to our work in progress folder? Should we instead be issuing in the Shared folder with S2 Suitable for Information, as below? If so then what revision code should be used? If it's work in progress then it's meant to have a revision code with a two-integer suffix (e.g. P01.01) but ISO 19650 UK Annex states (NA.4.3 Revision) that this kind of revision code is for work in the Work in Progress folder/state. Which no one else has access to....
S1 - Suitable for Co-ordination - I find it a little odd that the first status code is 'for co-ordination' when we would typically issue information 'for comment' or 'for approval' before we issue 'for co-ordination'.
S2 - Suitable for Information - simple enough I guess, but no explanation in the ISO 19650 UK Annex defining it accurately.
S3 - Suitable for Review and Comment - see comment above on S1
S4 - Suitable for Stage Approval - what is a "stage"? Can it mean any self-defined stage (e.g. "layout approval" stage). Or does it mean RIBA Work Stages? Or does it simply mean this is suitable for final approval before moving to a 'for construction' status?
S6 - Suitable for PIM (project information model) Authorisation - straightforward, information that's ready to be authorised for management of the construction project
S7 - Suitable for AIM (asset information model) Authorisation - straightforward, information that's ready to be authorised for asset management of the project
A1, etc - Authorised and accepted - straightforward, approved and accepted information for construction
B1, etc - Partial sign-off (with comments) - straightforward, good way of revising 'for construction' information
Published (for AIM acceptance)
CR - As constructed record document - straightforward, 'as built'
