How to Write a BIM Execution Plan: A Contractor's Guide
A BIM Execution Plan (BEP) is the foundation of any VDC program. Without one, every team member has a different idea of what the model is for, who owns it, and what it needs to contain. Here's how to write one that actually gets used.
A BIM Execution Plan (BEP) is a project-specific document that defines how BIM will be implemented across the project team. It is not a template you fill out and file away it is a living agreement that governs how the VDC program operates from preconstruction through closeout.
Why Most BEPs Fail
Many BEPs are written to satisfy a contract requirement, not to guide actual work. They are filled with boilerplate from old projects, list software versions that nobody checks, and get updated once before being forgotten.
A BEP that nobody reads is worse than no BEP at all it creates the appearance of VDC governance without the reality. Teams assume standards are being followed because there is a document, when in practice every sub is modeling to their own preferences.
A BEP that actually improves project outcomes is specific, enforceable, and referenced in every coordination meeting. Here is how to write one.
The 7 Core Sections of an Effective BEP
1. Project Information and BIM Goals
Start with the basics: project name, owner, GC, key subcontractors, BIM authoring tools, and common data environment (CDE). Then define your BIM goals not generic goals but specific and measurable ones:
- Achieve zero unresolved hard clashes prior to MEP rough-in on each floor
- Deliver a LOD 400 as-built model to the owner within 60 days of substantial completion
- Produce 4D animations for each major construction phase milestone for owner review
2. Model Standards
Define the standards all teams must follow:
- Coordinate reference system and survey point
- File naming conventions
- Object naming and shared parameter requirements
- Level/workset structure
- Model division (who models what)
3. Level of Development (LOD) Matrix
For each discipline and project phase, define the required LOD. This prevents subcontractors from over-modeling (wasting time) or under-modeling (creating coordination gaps).
4. Clash Detection Protocol
- Which discipline pairs get tested
- Clash test settings (hard vs. soft, tolerance values)
- Meeting frequency and format
- Status tracking workflow and ownership matrix
- Definition of "resolved" what constitutes sign-off
5. Deliverables Schedule
List every BIM deliverable with a due date and responsible party: model milestones, clash reports, 4D animations, as-built model handover.
6. Collaboration and File Exchange
- Common data environment (BIM 360 / ACC / Procore)
- Model publishing schedule (how often subs update their models weekly is standard)
- File formats for exchange
- Access and permission structure
7. Quality Control
Who reviews models before they are published to the CDE? What are the QC criteria? How are non-conformances flagged and resolved?
"The best BEPs are built in the room, with the whole team. If the MEP sub doesn't know about model naming requirements until construction starts, they will not follow them and you cannot hold them to a document they never agreed to."
Practical Tips
Write the BEP with the project team, not for them. The BIM kickoff meeting held before any modeling begins is where the BEP is developed and agreed to. Every trade representative should understand and sign off on the standards that apply to their scope.
Keep it short. A 60-page BEP that nobody reads is less useful than a 15-page one that becomes the team's reference document. Cut every generic statement that could apply to any project if it is not specific to this job, it does not belong in the BEP.
Revisit it. At major project milestones design completion, construction start, substantial completion review the BEP and update anything that no longer reflects reality. A BEP that is 12 months out of date is not a governance document.
