BIM capability
BIM execution plans, information delivery plans and compliance frameworks aligning MEP appointments to employer information requirements and ISO 19650 information management processes.
BIM execution planning translates employer information requirements into actionable delivery protocols for each project appointment. The BIM execution plan defines modelling standards, deliverable schedules, coordination procedures, CDE workflows and compliance verification methods that govern all digital information production on the project.
Information requirements compliance is not a document exercise — it is verified through milestone audits, deliverable registers and CDE status tracking. The BIM manager maintains alignment between what the EIR demands, what the BEP commits and what production teams actually deliver at each project stage.
ISO 19650 provides the information management framework: appointment scope, exchange information requirements, master information delivery plan and task information delivery plans form a hierarchy linking client objectives to discipline-specific delivery obligations.
Compliance assessments compare delivered information against EIR and BEP requirements at defined gates. Non-conformances trigger remediation plans with re-verification before authorised issue. The compliance register provides auditable evidence for client reviews, contractor onboarding and handover acceptance.
Clients issuing formal employer information requirements expect appointed teams to respond with BIM execution plans demonstrating capability to deliver specified information at defined milestones. Generic template BEPs that are not project-specific fail compliance review and delay appointment confirmation.
On design-build and PPP contracts, the BIM execution plan becomes a binding delivery instrument. MEP appointments must define their information production scope, CDE access, resource allocation and compliance verification responsibilities within the broader project information management structure.
Compliance extends through handover to operational phase information requirements where ISO 19650-3 governs asset information delivery. The BEP establishes the bridge between capital delivery compliance and operational information continuity.

BEP compliance integrates MEP information delivery with architectural and structural appointments through shared MIDP entries and coordinated milestone gates. MEP exchange information requirements reference interface elements requiring cross-appointment coordination.
Engineering calculation reports, specifications and drawings are listed as linked deliverables in the TIDP, establishing traceability between analytical outputs and model-based information containers.
Contractor and subcontractor information requirements are addressed through exchange information definitions in the BEP. MEP shop drawing and fabrication model requirements are scoped with compliance verification methods appropriate to the appointment boundary.

The EIR is the client's specification of required information. The BEP is each appointment's response defining how they will deliver against those requirements, including standards, processes and resources.
No. The BEP must be project-specific, mapping to the issued EIR, defining deliverable schedules, CDE workflows and compliance methods for the actual project scope.
Compliance audits at milestone gates compare delivered information against EIR and BEP requirements using checklists, format verification and CDE status review. Results are recorded in the compliance register.
Non-conformances are logged with severity classification and remediation plan. Re-verification is required before authorised issue. Critical gaps may block milestone gate approval.
ISO 19650 defines the information management framework. The BEP is the project-specific implementation document that operationalises ISO 19650 requirements for each appointment.
