BIM Level of Development (LOD)

BIM Level of Development (LOD) Services & Deliverables

We define and deliver BIM models at specified Levels of Development (LOD) so project teams — from designers to contractors and owners — have clarity on the maturity, reliability, and usability of model information at every stage of design and construction. 

The Level of Development (LOD) framework categorizes the progressive completeness and reliability of BIM elements throughout a project. It ensures stakeholders share a common understanding of what information, precision, and usability to expect at each stage — from early conceptual design to field-verified as-built models. 

Why LOD Matters

Without a defined Level of Development, BIM models can be inconsistent or misunderstood, leading to rework, delays, and misaligned expectations. LOD provides a standardized framework that clarifies how much information and reliability each model element contains — helping teams make decisions, coordinate across disciplines, and trust the model throughout the project lifecycle. 

How LOD Integrates With Your Project
  • Aligned Deliverables: Specify what each team must deliver at each LOD milestone.
  • Consistent Expectations: Ensure all stakeholders understand model accuracy, data quality, and usage limits.
  • Better Coordination: Models at higher LODs promote clash detection, fabrication planning, and construction sequencing.
  • Reduced Risk: Clear LOD criteria minimize misunderstandings and help control costs and schedule
What We Deliver
  • LOD 100 – Conceptual Models: Basic geometric representations for early design and feasibility, supporting spatial planning and massing.
  • LOD 200 – Schematic Models: Approximate geometry and metadata for schematic design, preliminary coordination, and early cost input.
  • LOD 300 – Detailed Design Models: Accurate geometry and location data suitable for construction documentation and coordination.
  • LOD 350 – Interface & Coordination Models: Extended detail including systems interfaces, connections, and construction coordination.
  • LOD 400 – Fabrication & Assembly Models: High-fidelity models supporting fabrication, shop drawings, and construction sequencing.
  • LOD 500 – As-Built Models: Field-verified models reflecting what was built, used for facilities management and lifecycle planning.
Who This Service Is For
  • Design & BIM Managers — define model maturity expectations and deliverable requirements.
  • Architects & Engineers — align model content with project phases and coordination needs.
  • Contractors & Fabricators — ensure models are ready for construction and assembly planning.
  • Owners & Facility Teams — receive reliable as-built models for operations and asset management.
