This New Work Item will extend the basic information given in the EN ISO19650 and in the "Guidance to EN ISO 19650". It will detail and structure the concept of a Common Data Environment (CDE) as a workflow for the collaborative process of managing the information and information containers as solutions that fit to the management and project processes inherent for BIM

It may be necessary to introduce further concept details as elements for understanding and implementation. Archiving and versioning of information containers can become very complex when considering various typical information situations of a project.

Further elements, rules and terminology for information management and digitisation may need to be explained and technically framed in the context of a CDE. It will be a large advantage developing at the same time the "Open API for CDE" in TC442 WG2

In particular this Work Item will describe 

- how to link a CDE according to EN ISO 19650 to an already existing Asset Management Systems of the Asset Owner. 

- how to maintain and manage "living documents" like Information Models (AIM, PIM) 

- how to maintain, exchange and manage Information Requirements like (OIR, AIR, EIR) as well as BIM Execution Plans (BEP) 

- how to use and implement Information Delivery Plans for the above entities (MIDP and TIDP in ISO 19650) 

- how to manage and collaborate between various Information Containers like models, requirements, container states 

- how to support Process Workflow by a CDE based on the IDM concept

It will simply have to describe how to provide "Common Data Environment" throughout the whole life cycle (horizontal aspect) and throughout the spectrum of management levels and stakeholders (vertical aspect).

In the work item proposed here, all important terms, processes and targets are to be expanded around the CDE concept. Relations to already existing normatives will be given.

Informative attachments such as templates and examples could be provided to the benefit of planner, supplier and operator as further guidelines.
