DE3, part of CIBSE’s Digital Engineering Series, is intended for those that generate, complete and review BIM Execution Plans. Four free templates supplement this guidance note; links to these documents can be found below. 

The concept of the BIM Execution Plan is that it is a response to an Employer’s Information Requirements document (EIR), setting out the proposals for how a project can be delivered digitally.


DE3 is based on PAS 1192-2:2013 and provides guidance to users of BIM Execution Plans as to how information may be sought, generated and reviewed, so as to add value to the employer. 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 standing of a PAS should be considered.


The BEP process is there to make the information exchanges between the design teams, construction teams and their employer predictable and well defined, using formats that are interoperable between the various software platforms used.

We have also provided templates that should help with organise Model Review Meetings, which are available here:
