A BIM Execution Plan (BEP) shouldn't be a document that everyone signs and nobody reads again. It should define how the project will actually use BIM, who is responsible for what, and what information must be delivered.
Before signing off, the project team should be able to answer the following questions.
What a BEP actually needs to answer
What BIM is for, specifically
Coordination, shop drawings, fabrication, takeoff, sequencing, handover — each creates different requirements.
Who owns what
Authoring, coordination, clash review, issue management and approval should each have a named owner.
A working document
If a new team member joined tomorrow, could they use it to understand how BIM is supposed to work?
What is BIM actually being used for?
Define the real uses: design coordination, shop drawings, fabrication, quantity takeoff, construction sequencing, as-built information or handover. Different uses create different requirements, and a BEP that doesn't name them tends to default to the lowest common denominator.
Who owns what
- BIM management
- Model authoring
- Coordination
- Clash review
- Issue management
- Model approval
- Drawing production
- Final information exchange
What are the model standards, and what level of information is required?
The BEP should address naming, units, coordinates, file structure, worksets, families/content, parameters, model versions and exchange formats — and define the expected geometry and information for each stage. Avoid treating LOD as a single magic number: a fabrication model and a design coordination model serve different purposes and need different detail.
Read the BEP as an operational document, not a compliance document — if a new team member joined tomorrow, could they use it to understand how BIM is supposed to work?
How coordination and QA/QC will actually work
Specify federation, clash rules, tolerances, meeting frequency, issue tracking, responsibilities and deadlines — and how a clash moves from detection to decision to closure. Define model health checks, discipline reviews, coordination checks, drawing checks and approval gates too. A clear QA process matters even more when work is split between internal and outsourced teams; see our model QA breakdown for how that actually runs.
How information moves, and what happens when requirements change
Define the common data environment, file formats, naming, revision rules, transmittals and permissions, so the team always knows which file is current and which is approved. Projects change — the BEP should also state how changes are proposed, reviewed, recorded and incorporated into the model.
A useful BEP reduces ambiguity before it becomes rework
This is the same structure we work from on BIM coordination engagements and the reason we build every project around federated, discipline-owned models rather than one shared file — the BEP is where that structure gets agreed before modelling starts.
