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.
Structural Services – LOD 100 → Concept (Early Vision)
Meaning: High-level structural intent without material commitment.
Includes: Conceptual structural massing, preliminary column grids, core locations, and indicative load paths aligned with building form and orientation.
Outcome: Rapid feasibility studies, early span and height validation, zoning compliance checks, and informed go/no-go decisions before detailed engineering.
Critical Insight: Early structural clarity avoids fundamental redesign later.
Structural Services – LOD 200 → Early Design (Schematic Design)
Meaning: Organized but approximate structural systems.
Includes: Preliminary framing layouts, approximate beam and column sizing, slab systems, core definition, and early assumptions for load transfer and constructability.
Outcome: Clear structural intent, realistic early costing models, and strong alignment with architectural and MEP systems.
Critical Insight: Most structural coordination risks are resolved here.
Structural Services – LOD 300 → Detailed Design (Accurate & Coordinated)
Meaning: Fully engineered, measurable structural model.
Includes: Accurate member sizes, exact placement of beams, columns, slabs, walls, foundations, coordinated penetrations, and reliable quantity take-offs.
Outcome: Reduced RFIs, smooth consultant approvals, clash-free coordination, and predictable construction documentation.
Critical Insight: This stage eliminates the majority of structural site issues.
Structural Services – LOD 350/400 → Build-Ready (Fabrication Precision)
Meaning: Fabrication- and construction-ready structural detailing.
Includes: Connection details, reinforcement layouts, embeds, anchors, openings, tolerances, sequencing logic, and shop drawing–level clarity.
Outcome: Faster fabrication approvals, minimal site rework, accurate prefabrication, controlled erection, and confident field execution.
Critical Insight: Converts structural design intent into build-ready certainty.
Structural Services – LOD 500 → As-Built (Verified Digital Twin)
Meaning: Final verified structural representation of the built condition.
Includes: Confirmed as-built geometry, actual member sizes, connection updates, field modifications, and validated load paths.
Outcome: Reliable asset records, safe renovations, accurate assessments, and long-term structural lifecycle documentation.
Critical Insight: Becomes the owner’s definitive structural reference for decades.
This structural LOD framework delivers certainty across design, fabrication, and construction—ensuring engineers, fabricators, and contractors always work from accurate, coordinated, and build-ready information.
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.
