DE4: Common Data Environments

DE4, part of CIBSE’s Digital Engineering Series, is intended for those that specify, commission, and use Common Data Environments (CDEs).

It is based on BS 1192:2007+ A2:2016 and PAS 1192-2:2013 and provides guidance to users of CDEs as to how data can be added and retrieved from a CDE and what principles are behind the use of them. It is not intended to be an exhaustive or definitive document and it will be necessary for users of the guidance given to exercise their own professional judgement when deciding whether to abide by or depart from it.

The concept of the CDE is to provide a central repository of information, be that graphical or data based. This information can then be shared in a structured way, with layers of checking and approval to ensure that the information is correct and suitable.

There is no single method of delivering a Common Data Environment. It can be based on the use of folders, use of an Electronic Document Management System (EDMS) or a bespoke cloud-based solution. It will depend on the nature and scale of the project which solution is chosen.
The choice of CDE solution can be made by the employer, their representative or the lead designer. If the employer or their representative choose the CDE solution, then this should be stated in the Employer’s Information Requirements (EIR). If the lead designer chooses, then this should be stated in the BIM Execution Plan (BEP).
It is important for all actors on a project to engage with and use the CDE. It will be the single source of truth that designers, constructors, manufacturers and facility managers require to perform their duties.
