UK National Annex 2021 Discipline vs Role

NA.2 Information container identification (ID) – Discipline

The field ‘Role’ has been renamed ‘Discipline’ in the most recent edition of BS EN ISO-2 19650-2:2018 NA February 2021.

The previously used role codes, derived from BS 1192:2007, had conflicts associated with contractual statuses such as client, contractor, and subcontractor, or sometimes inappropriate use of occupation title such as an architect.[1]

As a result, the list of standard codes has been revised with the goal of aligning disciplines with project activities; a comparison of changes is shown in Table 1.
