BIM Execution Plan (BEP) Framework
This BEP framework was developed for a 450,000 sq ft regional hospital project in Texas. It has been anonymized and generalized for use as a reference. The framework covers the minimum requirements that should appear in every project-specific BEP. Actual projects may require additional sections depending on owner requirements, delivery method, and local code constraints.

3. LOD Responsibility Matrix
Each discipline's model must meet a minimum LOD at each project phase. LOD per AIA G202-2013.
| Discipline | SD (Responsible) | DD (Responsible) | CD/Coordination (Responsible) | Fabrication/Install (Responsible) |
|---|---|---|---|---|
| Architectural | LOD 200 (AOR) | LOD 300 (AOR) | LOD 350 (AOR) | LOD 350 (AOR) |
| Structural | LOD 200 (SOR) | LOD 300 (SOR) | LOD 350 (SOR) | LOD 350 (SOR) |
| Mechanical (Duct) | LOD 200 (MEP) | LOD 300 (MEP) | LOD 350 (MEP) | LOD 400 (Fabricator) |
| Mechanical (Piping) | LOD 200 (MEP) | LOD 300 (MEP) | LOD 350 (MEP) | LOD 400 (Fabricator) |
| Electrical | LOD 200 (MEP) | LOD 300 (MEP) | LOD 350 (MEP) | LOD 400 (Fabricator) |
| Plumbing | LOD 200 (MEP) | LOD 300 (MEP) | LOD 350 (MEP) | LOD 400 (Fabricator) |
| Fire Protection | LOD 200 (MEP) | LOD 300 (MEP) | LOD 350 (MEP) | LOD 400 (Fabricator) |
| Medical Gas | LOD 200 (MEP) | LOD 300 (MEP) | LOD 350 (MEP) | LOD 400 (Fabricator) |
4. Clash Test Configuration
| Selection Set A | Selection Set B | Tolerance | Type | Priority |
|---|---|---|---|---|
| Ductwork | Structure | 3" | Hard | P1 - Critical |
| Piping (all) | Structure | 3" | Hard | P1 - Critical |
| Ductwork | Piping | 3" | Hard | P2 - High |
| Electrical (cable tray) | Structure | 3" | Hard | P2 - High |
| Ductwork | Electrical (conduit) | 6" | Soft (clearance) | P3 - Medium |
| Piping | Electrical (conduit) | 6" | Soft (clearance) | P3 - Medium |
| Medical Gas | All trades | 3" | Hard | P1 - Critical |
| Equipment | All trades | 12" | Soft (access) | P2 - High |
Note: Our experience across 500+ coordinated projects shows that over-tight clearance tolerances (1-2") increase coordination effort by 30-40% without proportional construction benefit. The 3" hard clash / 6" soft clearance standard balances rigor with practical constructability.
5. Coordination Meeting Schedule
| Phase | Frequency | Duration | Key Milestone |
|---|---|---|---|
| Model QC (Week 1) | Once | 2 hours | Model Quality Report accepted by all trades |
| Initial Coordination (Weeks 2-6) | Weekly | 90 min | Clash count below 500 |
| Detailed Coordination (Weeks 7-11) | Weekly | 90 min | Clash count below 50 |
| Prefab Gate Review (Week 12) | Once | 2 hours | Zero open clashes per zone |
| Close-Out Review (Week 14) | Once | 1 hour | Final coordinated model + as-built log |
| Post-Award (ongoing) | Monthly | 60 min | Field verification updates |
6. Prefabrication Gate Criteria
No MEP prefabrication release is authorized until ALL of the following criteria are met for the release zone:
- Clash-free: Zero open hard clashes in the release zone. All soft (clearance) clashes documented and trade-accepted.
- LOD verified: All system elements in the release zone modeled at minimum LOD 400 (fabrication-level detail including hangers, supports, connections).
- Field-verified: Model-to-field accuracy confirmed within 1" for at least 20% of MEP tie-in points in the release zone (laser scan or physical measurement).
- Fabricator-ready: Federated model exported to fabricator's native format (SDS/2, CAMduct, TrimPipe) and confirmed compatible by the fabricator.
- BEP-compliant: Model file naming, version, and status meet BEP file standard requirements.
- Approved: Gate release form signed by GC BIM lead, MEP coordinator, and fabricator representative.
