LOD explains how detailed, accurate, and build-ready your BIM model is at every stage. As the LOD increases, uncertainty drops—giving you clearer coordination, fewer RFIs, faster approvals, reduced rework, and a smoother, more predictable construction process.
Architectural Services – LOD 100 → Concept (Early Vision)
Meaning: High-level architectural intent without design commitment.
Includes: Conceptual building massing, basic form, height, orientation, and approximate spatial relationships without detailed elements or systems.
Outcome: Rapid feasibility studies, early zoning and massing validation, design direction clarity, and confident go/no-go decisions before detailed design investment.
Critical Insight: Early architectural clarity prevents costly rework and strategic misdirection.
Architectural Services – LOD 200 → Early Design (Schematic Design)
Meaning: Organized but still approximate architectural layouts.
Includes: Preliminary walls, floors, openings, core layouts, vertical circulation, and early coordination assumptions with structure and MEP systems.
Outcome: Clear design intent, realistic early cost alignment, improved stakeholder understanding, and reduced downstream design uncertainty.
Critical Insight: Most architectural misalignment is resolved at this stage.
Architectural Services – LOD 300 → Detailed Design (Accurate & Coordinated)
Meaning: A precise, measurable architectural model suitable for CDs.
Includes: Accurate dimensions, exact wall assemblies, door/window locations, floor levels, finishes intent, code-compliant layouts, and coordinated interfaces with structural and MEP systems.
Outcome: Fewer RFIs, smoother consultant coordination, reliable quantity take-offs, and predictable construction documentation.
Critical Insight: This stage eliminates the majority of architectural site conflicts.
Architectural Services – LOD 350/400 → Build-Ready (Construction Precision)
Meaning: Construction- and installation-ready architectural detail.
Includes: Detailed wall assemblies, thresholds, junctions, tolerances, penetrations, edge conditions, constructability logic, and sequencing clarity.
Outcome: Faster submittal approvals, minimal site errors, controlled execution, reduced change orders, and clearer contractor guidance.
Critical Insight: Converts design intent into build-ready architectural certainty.
Architectural Services – LOD 500 → As-Built (Verified Digital Twin)
Meaning: Final verified architectural representation of what is built.
Includes: Exact as-built dimensions, confirmed layouts, field modifications, finish records, and alignment with actual site conditions.
Outcome: Reliable facilities management, confident renovations, accurate space planning, and long-term asset documentation.
Critical Insight: Becomes the owner’s authoritative architectural record for decades.
This LOD framework ensures complete clarity, predictable coordination, and zero surprises across design, fabrication, and construction — giving every stakeholder the right information at the right time for faster decisions and smoother project delivery.
Increase production bandwidth, eliminate execution bottlenecks, and scale delivery with
confidence
while protecting margins and maintaining performance standards.
Strengthen your delivery infrastructure, increase output capacity, and support larger
project pipelines
without expanding your internal workforce.
