The Common Data Environment: Process Before Platform

From Reimagining AEC · 46:14

Show by Sepehr Abrishami

On Reimagining AEC, his own podcast, Dr Sepehr Abrishami asks what ISO 19650 requires of a common data environment as a process, as distinct from the platform someone bought. A hypothetical school extension, Northgate Academy, where a coordinator could fix a subcontractor's facade model in ten minutes or send it back, carries the argument through the definition in ISO 19650-1, the three states and the archive, the two transitions and who owns them, status, revision and classification under the UK National Annex, the seven-field container identifier, and how to specify and audit an environment against clause 5.1.7 of ISO 19650-2.Chapters0:00 Opening: the facade model the platform lets anyone edit3:14 The definition in three parts, workflow and solution, and the delivery cycle8:59 The three states, the archive, the two transitions and who owns them18:27 Status, revision and classification under the UK National Annex26:23 The container identifier and its seven fields34:15 Writing a specification from clause 5.1.737:33 Auditing the environment, security and the operational environment42:45 CloseAfter listening, you should be able to:Define the common data environment in its three parts at clause 3.3.15 of ISO 19650-1, separate the workflow the standard specifies from the solution it leaves open, and place the environment within the information delivery cycle of clause 6, including the two checks at a stage boundary.Name the three states that hold a current revision, explain why the archive is a journal rather than a fourth state, state what each state permits, and identify who owns each transition and what precondition must hold before it.Assign a UK status code by naming the step of ISO 19650-2 that produces it, apply the revision conventions and their pairing with status, state the compliant treatment of the deprecated B series, and apply classification as the third mandatory attribute.Decompose a container identifier into its seven fields, apply the delimiter and codification rules of the UK National Annex, explain why status and revision do not belong in the identifier, and write a four-part naming finding.Write a functional and non-functional requirement set traceable to clause 5.1.7 of ISO 19650-2, and audit an environment against the standard, the National Annex and the project information standard, assigning severity so that each finding reaches the party who can act on it.Identify the decisions that belong to the security-minded approach of ISO 19650-5, and separate the project environment from the operational environment established under ISO 19650-3.ReferencesBritish Standards Institution.
